Intravenous initial bolus during prophylactic norepinephrine infusion to prevent spinal hypotension for cesarean delivery: A randomized controlled, dose-finding trial. J Clin Anesth 2024; 97:111562. [PMID: 39047530 DOI: 10.1016/j.jclinane.2024.111562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 07/01/2024] [Accepted: 07/18/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND Previous studies have shown that a 0.05 μg/kg/min of norepinephrine infusion in combination with an initial bolus reduces the incidence of spinal hypotension during cesarean delivery. The initial norepinephrine bolus influences the incidence of spinal hypotension during continuous norepinephrine infusion; however, the ideal initial bolus dose for 0.05 μg/kg/min of continuous infusion remains unknown. METHODS This randomized, controlled, dose-finding study randomly allocated 120 parturients scheduled for elective cesarean delivery to receive initial bolus doses of 0, 0.05, 0.10, and 0.15 μg/kg of norepinephrine, followed by continuous infusion at a rate of 0.05 μg/kg/min. The primary outcome was the dose-response relationship of the initial norepinephrine bolus in preventing the incidence of spinal hypotension. Spinal hypotension was defined as systolic blood pressure (SBP) decreased to <80% of the baseline value or to an absolute value of <90 mmHg from intrathecal injection to delivery, and severe spinal hypotension was defined as SBP decreased to <60% of the baseline value. The secondary outcomes included the incidence of nausea and/or vomiting, hypertension, and bradycardia, as well as the Apgar scores and results of the umbilical arterial blood gas analysis. The effective dose (ED) 90 and ED95 were estimated using probit regression. RESULTS The per-protocol analysis included 117 patients. The incidence of spinal hypotension varied significantly among the groups: Group 0 (51.7%), Group 0.05 (44.8%), Group 0.10 (23.3%), and Group 0.15 (6.9%). The ED90 and ED95 values were 0.150 μg/kg (95% confidence interval [CI], 0.114-0.241 μg/kg) and 0.187 μg/kg (95% CI, 0.141-0.313 μg/kg), respectively. However, the ED95 value fell outside the dose range examined in this study. The incidence of severe spinal hypotension differed significantly (P = 0.02) among Groups 0 (17.2%), 0.05 (10.3%), 0.10 (3.3%), and 0.15 (0.0%); however, the incidence of hypertension and bradycardia did not. The incidence of nausea and/or vomiting decreased with an increase in the initial bolus dose (P = 0.03). The fetal outcomes were comparable among the groups. CONCLUSIONS An initial bolus of 0.150 μg/kg of norepinephrine may be the optimal dose for preventing spinal hypotension during cesarean delivery with a continuous infusion rate of 0.05 μg/kg/min, and does not significantly increase the incidence of hypertension but substantially reduces the risk of nausea and/or vomiting.

PLoS One 2024; 19:e0305913. [PMID: 38917195 PMCID: PMC11198823 DOI: 10.1371/journal.pone.0305913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 05/31/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND The aim of this study was to evaluate the impact of intravenous palonosetron compared to ondansetron on hypotension induced by spinal anesthesia in women undergoing cesarean section. METHODS Fifty-four women scheduled for elective cesarean section were, randomly allocated to ondansetron group (n = 27) or palonosetron group (n = 27). Ten minutes prior to the administration of spinal anesthesia, participants received an intravenous injection of either ondansetron or palonosetron. A prophylactic phenylephrine infusion was initiated immediately following the intrathecal administration of bupivacaine and fentanyl. The infusion rate was titrated to maintain adequate blood pressure until the time of fetal delivery. The primary outcome was total dose of phenylephrine administered. The secondary outcomes were nausea or vomiting, the need for rescue antiemetics, hypotension, bradycardia, and shivering. Complete response rate, defined as the absence of postoperative nausea and vomiting and no need for additional antiemetics, were assessed for up to 24 hours post-surgery. RESULTS No significant differences were observed in the total dose of phenylephrine used between the ondansetron and palonosetron groups (387.5 μg [interquartile range, 291.3-507.8 μg versus 428.0 μg [interquartile range, 305.0-507.0 μg], P = 0.42). Complete response rates also showed no significant differences between the groups both within two hours post-spinal anesthesia (88.9% in the ondansetron group versus 100% in the palonosetron group; P = 0.24) and at 24 hours post-surgery (81.5% in the ondansetron group versus 88.8% in the palonosetron group; P = 0.7). In addition, there was no difference in other secondary outcomes. CONCLUSION Prophylactic administration of palonosetron did not demonstrate a superior effect over ondansetron in mitigating hemodynamic changes or reducing phenylephrine requirements in patients undergoing spinal anesthesia with bupivacaine and fentanyl for cesarean section.

Abstract
STUDY OBJECTIVE During cesarean section, hypotension is a frequent side effect of spinal anesthesia. As a sitting or lateral position is required for spinal anesthesia performance, which of these two positions is more likely to cause intraoperative nausea, vomiting, and hypotension is still unknown. This meta-analysis compared the effects of these two positions on maternal hemodynamics and intraoperative nausea and vomiting. DESIGN Systematic review and meta-analysis. SETTING Operating room. PATIENTS This study included 803 patients from 12 randomized controlled trials (RCTs). INTERVENTIONS Neuraxial anesthesia in sitting position vs. lateral position. MEASUREMENTS We chose RCTs comparing the effects of spinal anesthesia in the sitting and lateral positions on maternal hemodynamics by thoroughly searching PubMed, Embase, the Cochrane Library, and the Web of Science for articles published from database inception until October 31, 2022. The Cochrane Handbook was used to assess the methodological quality of each RCT; the results were analyzed using RevMan 5.4 software; and the Egger test was used to assess publication bias. MAIN RESULTS 12 randomised controlled trials with 803 participants were ultimately included in the final analysis. No significant differences were observed between the two positions in terms of the incidence of hypotension(RR, 0.82; 95% CI, 0.58-1.16; P = 0.26; I2 = 66%), lowest systolic blood pressure(MD, -0.81; 95% CI, -7.38-5.75; P = 0.81; I2 = 86%), the dose of ephedrine(MD, -1.19; 95% CI, -4.91-2.52; P = 0.53; I2 = 83%), and number of parturients requiring ephedrine(RR, 0.97; 95% CI, 0.64-1.46; P = 0.88; I2 = 74%). For the incidence of intraoperative nausea and vomiting, there was no statistical difference between the two positions. CONCLUSION Parturients undergoing elective cesarean section under spinal anesthesia in the sitting or lateral position experienced similar incidence of hypotension, and there were no significant differences between these two positions in terms of the amount of ephedrine administered or the number of patients needing ephedrine. In both positions, the frequency of nausea and vomiting was comparable. The ideal position for anesthesia can be chosen based on the preferences and individual circumstances of the parturient and anesthesiologist.

Abstract
Cesarean sections are commonly performed under spinal anesthesia, which can lead to hypotension, adversely affecting maternal and fetal outcomes. Hypotension following spinal anesthesia is generally defined as a blood pressure of 80-90% below the baseline value. Various strategies have been implemented to reduce the incidence of spinal anesthesia-induced hypotension. The administration of vasopressors is a crucial method for preventing and treating hypotension. In the past decade, phenylephrine, a primarily alpha-adrenergic agonist, has been the preferred vasopressor for cesarean sections. Recently, norepinephrine, a potent alpha-agonist with modest beta-agonist activity, has gained popularity owing to its advantages over phenylephrine. Vasopressors can be administered via a bolus or continuous infusion. Although administering boluses alone is simpler in a clinical setting, continuous prophylactic infusion initiated immediately after spinal anesthesia is more effective in reducing the incidence of hypotension. Tailoring the infusion dose based on the patient's body weight and adjusting the rate in response to blood pressure changes, in addition to using a prophylactic or rescue bolus, helps reduce blood pressure variability during cesarean sections under spinal anesthesia until neonatal delivery.

Am J Obstet Gynecol 2024:S0002-9378(24)00447-2. [PMID: 38521233 DOI: 10.1016/j.ajog.2024.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 03/03/2024] [Accepted: 03/13/2024] [Indexed: 03/25/2024]
Abstract
BACKGROUND Contemporary guidance for preoperative feeding allows solids up to 6 hours and clear fluids up to 2 hours before anesthesia. Clinical trial evidence to support this approach for cesarean delivery is lacking. Many medical practitioners continue to follow conservative policies of no intake from midnight to the time of surgery, especially in pregnant women. OBJECTIVE This study aimed to evaluate the pragmatic approach of permitting free access to water up to the call to dispatch to the operating theater vs fasting from midnight in preoperative oral intake restriction for planned cesarean delivery under spinal anesthesia on perioperative vomiting and maternal satisfaction. STUDY DESIGN A randomized controlled trial was conducted in the obstetrical unit of the University of Malaya Medical Centre from October 2020 to May 2022. A total of 504 participants scheduled for planned cesarean delivery were randomized: 252 undergoing preoperative free access to water up to the call to dispatch to the operating theater (intervention group) and 252 undergoing fasting from midnight (fasting arm). The primary outcomes were perioperative vomiting and maternal satisfaction. Analyses were performed using t test, Mann-Whitney U test, and chi-square test, as appropriate. RESULTS Of note, 9 of 252 patients (3.6%) in the intervention group and 24 of 252 patients (9.5%) in the control group had vomiting at up to 6 hours after completion of cesarean delivery (relative risk, 0.38; 95% confidence interval, 0.18-0.79; P=.007), and the maternal satisfaction scores (0-10 visual numerical rating scale) were 9 (interquartile range, 8-10) in the intervention group and 5 (interquartile range, 3-7) in the control group (P<.001). Assessed before dispatch to the operating theater, feeling of thirst was reported by 69 of 252 patients (27.4%) in the intervention group and 134 of 252 patients (53.2%) in the control group (relative risk, 0.52; 95% confidence interval, 0.41-0.65; P<.001), capillary glucose levels were 4.8±0.7 mmol/L in the intervention group and 4.9±0.8 mmol/L in the control group (P=.048), and preoperative intravenous fluid hydration was commenced in 49 of 252 patients (19.4%) in the intervention group and 76 of 252 patients (30.2%) in the control group (relative risk, 0.65; 95% confidence interval, 0.47-0.88; P=.005). In the operating theater, ketone was detected in the catheterized urine in 38 of 252 patients (15.1%) in the intervention group and 78 of 252 patients (31.0%) in the control group (relative risk, 0.49; 95% confidence interval, 0.25-0.59; P<.001), and the numbers of doses of vasopressors needed to correct hypotension were 2.3±1.7 in the intervention group and 2.7±2.2 in the control (P=.009). The recommendation rates for preoperative oral intake regimen to a friend were 95.2% (240/252) in the intervention group and 39.7% (100/252) in the control group (relative risk, 2.40; 95% confidence interval, 2.06-2.80; P<.001), in favor of free access to water. Other assessed maternal and neonatal outcomes were not different. CONCLUSION Compared with fasting, free access to water in planned cesarean delivery reduced perioperative vomiting and was strongly favored by women. In addition, several pre- and intraoperative secondary outcomes were improved. However, postcesarean delivery recovery and neonatal outcomes were not different.

Prophylactic intravenous norepinephrine for the prevention of hypotension during spinal anesthesia for elective cesarean section: a systematic review and dose-response meta-analysis of randomized controlled trials. Front Pharmacol 2023; 14:1247214. [PMID: 37795034 PMCID: PMC10546307 DOI: 10.3389/fphar.2023.1247214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 09/04/2023] [Indexed: 10/06/2023] Open
Abstract
Introduction: In this study, we aimed to evaluate the potential dose-response relationship between prophylactic norepinephrine (NE) infusion rates and the risks of hypotension during cesarean section following spinal anesthesia. Methods: Randomized controlled trials with two or more NE doses for post-spinal hypotension prophylaxis during cesarean section were systematically searched in the MEDLINE, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and US Clinical Trials Registry databases until 31 July 2022. The primary outcome was the relative risk of maternal hypotension with different NE regimens (infusion rates or bolus doses). Secondary outcomes included the relative risks of maternal and fetal adverse events with different NE regimens. Results: Ten studies with 1,144 parturients were included for final analysis using restricted cubic splines and random-effects dose-response meta-analysis models. A significant dose-response relationship existed between NE infusion rates and the relative risks of maternal hypotension. Every 0.01 μg/kg/min increment in the NE infusion rate was associated with a 14% decrease in the incidence of post-spinal hypotension. ED50 and ED95 of NE infusion rates for post-spinal hypotension prophylaxis were estimated to be 0.046 (95% CI from 0.032 to 0.085) and 0.2 (95% CI from 0.14 to 0.37) μg/kg/min, respectively. However, a higher NE infusion rate was associated with a higher incidence of maternal hypertension. Conclusion: An increased NE infusion rate was associated with a decreased incidence of post-spinal hypotension but an increased incidence of hypertension. Therefore, 0.07 μg/kg/min was recommended as the initial NE infusion rate for clinical practice, as it was associated with the lowest risk of physician intervention for unstable hemodynamics after spinal anesthesia for cesarean delivery.

Abstract
OBJECTIVE Postoperative nausea and vomiting are regarded as a serious concern after thyroidectomy. Electroacupuncture shows the potential to reduce general anesthesia-related side effects. The aim of this study was to evaluate the efficacy of electroacupuncture in preventing postoperative nausea and vomiting that commonly occurs in patients after thyroidectomy. METHODS This study was a prospective randomized controlled trial with a two-arm, patient blind structure. Sixty-four participants were randomly assigned to the acupuncture (n = 35) or control (n = 29) group. Patients in the acupuncture group received electroacupuncture and intradermal press needles. The primary endpoint was the incidence and severity of postoperative nausea and vomiting, and secondary endpoints were the length of hospital stay, pain severity, and postoperative in-hospital morbidity. RESULTS The total incidence of postoperative nausea and vomiting was 40.6% (26/64). There was no difference in the incidence between the control (10/29, 34.5%) and acupuncture (16/35, 45.7%) groups (p = 0.362). The severity of postoperative nausea and vomiting was not different between the groups (p = 0.842). Length of hospitalization and postoperative complications were not different between the groups. CONCLUSION In this randomized controlled trial, electroacupuncture treatment after thyroidectomy is safe and comparable to conventional anti-emetic therapy.

Abstract
BACKGROUND Current guidelines recommend prophylactic vasopressor administration during spinal anesthesia for cesarean delivery to maintain intraoperative blood pressure above 90% of the baseline value. We sought to determine the optimum baseline mean arterial pressure (MAP) reading to guide the management of spinal hypotension. METHODS We performed a secondary analysis of data collected from normotensive patients presenting for elective cesarean delivery in a tertiary care institution from October 2018 to August 2020. We compared the magnitude of hypotension in patients who reported nausea versus those who did not, using a case-control design. Baseline MAPs at last office visit, morning of surgery, or operating room (pre-spinal) were determined. We calculated the duration and degree of hypotension using the area under the curve (AUC) when the MAP of the respective patient was below 90% of each baseline. RESULTS The patients who experienced nausea (n=45) had longer and more profound periods of hypotension than those who did not develop nausea (n=240). A comparison of AUC using MAP baseline at the last office visit or on the morning of surgery showed a statistically significant between-group difference, P=0.02, and P=0.005, respectively, and no significant between-group difference when 90% of the MAP baseline in the operating room was used. CONCLUSIONS Patients had the highest preoperative MAP in the operating room and the AUC was similar for those with and without nausea when the pre-spinal MAP baseline was used. Therefore, maintaining higher intraoperative blood pressure using individual pre-spinal MAP as baseline should reduce intraoperative maternal nausea.

Predictive Efficacy of the Perfusion Index for Hypotension following Spinal Anesthesia in Parturient Undergoing Elective Cesarean Section: A Systematic Review and Meta-Analysis. Diagnostics (Basel) 2023; 13:2584. [PMID: 37568947 PMCID: PMC10417716 DOI: 10.3390/diagnostics13152584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/01/2023] [Accepted: 08/02/2023] [Indexed: 08/13/2023] Open
Abstract
This meta-analysis assessed the predictive efficacy of perfusion index for hypotension following spinal anesthesia (SA) in parturients undergoing elective cesarean section (CS). Electronic databases, including Google Scholar, EMBASE, Cochrane Library, and MEDLINE, were searched from inception to June 2023. The primary outcome was the diagnostic accuracy of the perfusion index in predicting the probability of perioperative hypotension following SA. The review included 12 studies involving 2009 patients, published between 2017 and 2023. The pooled sensitivity and specificity were 0.81 (95% confidence interval (CI) = 0.72-0.87) and 0.75 (95% CI = 0.67-0.82), respectively. Additionally, the pooled area under the curve (AUC) was calculated as 0.84 (95% CI = 0.81-0.87), suggesting a moderate to good accuracy of the diagnostic test. Using Fagan's nomogram plot, the positive likelihood ratio (LR) and negative LR were found to be 3 and 0.26, respectively. The results demonstrated that the perfusion index exhibited an acceptable level of accuracy in predicting perioperative hypotension after spinal anesthesia in parturients undergoing elective CS. These findings highlight the potential value of incorporating a perfusion index as a useful tool for clinicians to integrate into routine clinical practice, which necessitates further large-scale studies for verification.

Preoperative Oral Carbohydrate (CHO) Supplementation Is Beneficial for Clinical and Biochemical Outcomes in Patients Undergoing Elective Cesarean Delivery under Spinal Anaesthesia-A Randomized Controlled Trial. J Clin Med 2023; 12:4978. [PMID: 37568381 PMCID: PMC10419905 DOI: 10.3390/jcm12154978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/25/2023] [Accepted: 07/27/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND Preoperative fasting and surgery cause metabolic stress, insulin resistance with ketosis, and postoperative nausea and vomiting (PONV). Oral carbohydrate loading strategy (CHO) improves outcomes in labor and general surgery. We aimed to compare the effectiveness of CHO with standard fasting in patients undergoing elective cesarean delivery (CD) under spinal anesthesia. METHODS A single-center, parallel, prospective randomized controlled trial (RCT) was conducted in a tertiary university obstetrics department at Pomeranian Medical University in Szczecin, Poland. Patients were randomly assigned (1:1 ratio) to the CHO group (oral carbohydrate 2 h before elective CD, n = 75) or the SF group (control-standard fasting, n = 73). The main outcome measures were incidence and severity of PONV at 6 and 24 h after CD, time to the first peristalsis, time to first bowel movement, and biochemical parameters indicating ketosis in mothers and their children. RESULTS A total of 148 adult females with singleton pregnancies undergoing elective CD under spinal anesthesia (ASA I and II) were included in the final analysis. At 24 h after CD, 8.0% from the CHO group vs. 20.55% reported three or more episodes of vomiting or dry retching as compared to patients in the SF group (p = 0.041). Preoperative CHO supplementation decreased preoperative feelings of hunger (p < 0.001) and thirst (p < 0.001). Laboratory results in the CHO group showed higher plasma pH (p = 0.001) and glucose (p < 0.001), lower F2-isoprostane in plasma (p = 0.049) and urine (p = 0.018), lower urine F2-isoprostane/creatinine ratio (p = 0.045) than in the SF group. HOMA-IR (p < 0.001) and lactate (p < 0.001) were higher in the CHO group than in the control group. CONCLUSIONS There was no significant difference in the incidence or severity of early PONV at 6 h. The incidence of vomiting or dry retching at 24 h after cesarean delivery was lower in the CHO group as compared to standard starvation, but the combined results of PONV frequency and severity on the Wengritzky scale did not differ between the two study groups. Preoperative CHO supplementation decreased preoperative feelings of hunger and thirst, enhancing the comfort of pregnant women. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT04069806.

Abstract
BACKGROUND AND OBJECTIVES Close monitoring of patients in the first 2 hours after cesarean delivery (CD) is crucial. Delays in shifting of the post-CD patients led to a chaotic environment in the postoperative ward, suboptimal monitoring, and inadequate nursing care. Our aim was to increase the percentage of post-CD patients shifted from transfer trolley to bed within 10 minutes of arrival in the postoperative ward from a baseline of 64% to 100%, and to maintain that rate for more than 3 weeks. METHODS A quality improvement team including physicians, nurses, and workers was constituted. Problem analysis revealed lack of communication among the caregivers as the main cause of delay. The percentage of post-CD patients shifted from trolley to bed within 10 minutes of being wheeled into the postoperative ward out of the total number of post-CD patients transferred from the operation theater to the postoperative ward was taken as the outcome indicator for the project. Multiple Plan-Do-Study-Act cycles based on the Point of Care Quality Improvement methodology were undertaken to achieve the target. Main interventions were: 1) written information of patient being transferred to operation theater for CD sent to the postoperative ward; 2) stationing of a duty doctor in the postoperative ward; and 3) keeping a buffer of 1 vacant bed in the postoperative ward. The data were plotted weekly as a dynamic time series chart and signals of change were observed. RESULTS Eighty-three percent (172 out of 206) of women were shifted in time by 3 weeks. After Plan-Do-Study-Act 4, the percentages kept improving leading to a median shift from 85.6% to 100% after 10 weeks post-initiation of the project. Sustainment was confirmed by continuing observations for 6 more weeks to ensure that the changed protocol was assimilated in the system. We found that all women were shifted within 10 minutes of their arrival in postoperative ward from trolley to bed. CONCLUSION Providing high-quality care to patients must be a priority for all health care providers. High-quality care is timely, efficient, evidence based, and patient-centric. Delays in transfer of postoperative patients to the monitoring area can be detrimental. The point of Care Quality Improvement methodology is useful and effective in solving complex problems by understanding and fixing the various contributory factors one by one. Reorganization of processes and available manpower without any extra investment in terms of infrastructure and resources is pivotal for long term success of a quality improvement project.

Abstract
Context The type of anesthesia in cesarean section can affect the mother and baby. This study aimed to determine the comparative effect of intrathecal hyperbaric bupivacaine vs. hyperbaric ropivacaine on maternal and neonatal outcomes after cesarean section. Evidence Acquisition PubMed, Web of Science, Embase, Google Scholar, IranDoc, MagIran, and Scopus databases were searched from 1 September 2022 to 1 November 2022. Eighteen clinical trials with 1542 patients were included in the analysis. Results There was no statistically significant difference in hypotension, bradycardia, and Apgar score between the 2 groups (P > 0.05). The risk of nausea (relative risk (RR), 1.526; 95% CI, 1.175 - 1.981; P = 0.001) and vomiting (RR, 1.542; 95% CI, 1.048 - 2.268; P = 0.02) caused by bupivacaine was 0.53% and 0.54% higher than that of ropivacaine. The incidence of shivering (RR, 2.24; 95% CI, 1.480 - 3.39; P = 0.00) was 2.24 times higher in the bupivacaine group than in the ropivacaine group. The average onset time of sensory block (standardized mean difference (SMD), -0.550; 95% CI, -1.054 to -0.045; P = 0.032) and motor block (SMD, -0.812; 95% CI, -1.254 to -0.371; P = 0.000) was significantly lower in the bupivacaine group than in the ropivacaine group. Conclusions Despite the fact that ropivacaine and bupivacaine are effective in cesarean section, ropivacaine is more favorable because of less hemodynamic changes, less duration of sensory and motor block, and fewer side effects, which are effective in patient recovery.

Abstract
PURPOSE OF REVIEW Postoperative/postdischarge nausea and vomiting (PONV/PDNV) remain relevant issues in perioperative care. Especially in ambulatory surgery, PONV can prevent discharge or lead to unplanned readmission. RECENT FINDINGS The evidence for the management of PONV is now quite good but is still inadequately implemented. A universal, multimodal rather than risk-adapted approach for PONV prophylaxis is now recommended. The evidence on PDNV is insufficient. SUMMARY PDNV management is based primarily on consequent prophylaxis and therapy of PONV.

Abstract
BACKGROUND Norepinephrine is effective in preventing spinal hypotension during cesarean birth; however, an optimal regimen has not been determined. We hypothesized that an initial bolus of norepinephrine improves efficacy of spinal hypotension prophylaxis beyond continuous norepinephrine alone. METHODS In this double-blind, controlled study, 120 patients scheduled for cesarean birth under spinal anesthesia were randomly allocated to receive a norepinephrine bolus at 0.05 or 0.10 μg/kg, followed by norepinephrine infusion at a rate of 0.05 μg·kg -1 ·min -1 . The primary outcome was the frequency of spinal hypotension during cesarean birth. The doses of the rescue drug (phenylephrine), frequency of nausea or vomiting, duration of hypotension, frequency of intraoperative hypertension, frequency of bradycardia, and fetal outcomes were also compared. RESULTS One-hundred-fifteen patients were included in the analysis. Compared with the 0.05 μg/kg group, the frequency of spinal hypotension was lower in the 0.10 μg/kg group (20.7% vs 45.6%; odds ratio [OR], 0.31; 95% confidence interval (CI), 0.14-0.71; P = .004). Fewer rescue doses of phenylephrine (0 [0,0] vs 0 [0,80]; 95% CI for the difference, 0 (0-0); P = .006) were required, and the frequency of nausea or vomiting was lower (5.2% vs 17.5%; OR, 0.26; 95% CI, 0.07-0.99; P = .04) in the 0.10 μg/kg group. The duration of hypotension was shorter in the 0.10 μg/kg group than that in the 0.05 μg/kg group (0 [0,0] vs 0 [0,2]; 95% CI for the difference, 0 [0-0]; P = .006). The incidence of intraoperative hypertension, frequency of bradycardia, and fetal outcomes were comparable between the 2 groups. CONCLUSIONS With a fixed-rate norepinephrine infusion of 0.05 μg·kg -1 ·min -1 , the 0.10 μg/kg initial bolus was more effective in reducing the incidence of spinal hypotension compared with the 0.05 μg/kg initial bolus.

Abstract
Background The study aimed to investigate whether prophylactic use of glycopyrrolate decreases the vasopressor requirements to prevent hypotension following spinal anesthesia during non-elective cesarean section. Method In this double-blind randomized clinical trial, 258 patients undergoing non-elective cesarean section were randomly assigned (1:1) to receive intravenous 0.2 mg glycopyrrolate or normal saline (placebo) before spinal anesthesia. The primary outcome was phenylephrine equivalent needed intraoperatively. Secondary outcomes included incidences of maternal hypotension, reactive hypertension, bradycardia, need for atropine, tachycardia, intraoperative nausea/vomiting, shivering, pruritus, dry mouth, dizziness; neonatal APGAR score at 1 min and 5 min, neonatal resuscitation needed, NICU admission and neonatal death. Results Three patients withdrew from the study due to failed spinal anesthesia. 128 patients in the glycopyrrolate group and 127 patients in the placebo group were analyzed. The mean phenylephrine equivalent needed was 1108.96 μg in the glycopyrrolate group and 1103.64 μg in the placebo group (mean difference, 5.32 μg [95% CI − 67.97 to 78.62]; P = 0.88). Hypotension occurred in 38 patients (30%) in the glycopyrrolate group as compared with 49 patients (39%) in the placebo group (P = 0.13). Tachycardia was reported in 70% of the participants in the glycopyrrolate group and 57% of those in the placebo group (P = 0.04). No statistically significant difference was noted in hypotensive episodes > 1, reactive hypertension, bradycardia, need for atropine, nausea, vomiting, shivering, and dry mouth between the two groups. Neonatal outcomes were similar in the two groups. Conclusion Prophylactic use of glycopyrrolate does not decrease the requirements of vasopressor to prevent hypotension in non-elective cesarean section under spinal anesthesia.

Abstract
BACKGROUND Intraoperative nausea and vomiting (IONV) is a common symptom during cesarean section (CS) delivery causing significant discomfort to patients. Combined spinal and epidural anesthesia (CSEA) can provide both intraoperative anesthesia and postoperative analgesia. During CSEA, it is reasonable to administer local anesthetics to the epidural space before patient complaints to compensate for the diminished effect of spinal anesthesia. Therefore, we hypothesized that intraoperative epidural administration of 2% mepivacaine would reduce the incidence of IONV. METHODS Patients who were scheduled for elective CS were randomly allocated to 2 groups. Patients and all clinical staff except for an attending anesthesiologist were blinded to the allocation. After the epidural catheter was inserted at the T11-12 or T12-L1 interspace, spinal anesthesia was performed at the L2-3 or L3-4 interspace to intrathecally administer 10 mg of 0.5% hyperbaric bupivacaine. Twenty min after spinal anesthesia, either 5 mL of 2% mepivacaine (group M) or saline (group S) was administered through an epidural catheter. Vasopressors were administered prophylactically to keep both the systolic blood pressure ≥ 80 % of the baseline value with the absolute value ≥ 90 mm Hg and the mean blood pressure ≥ 60 mm Hg. The primary endpoint was the incidence of IONV. The secondary endpoints were degree of nausea, the degree and incidence of pain, and Bromage score. RESULTS Ninety patients were randomized, and 3 patients were excluded from the final analysis. There was no significant difference in the incidence of IONV between the groups (58% in group M and 61% in group S, respectively, P = .82). In contrast, the incidence and degree of intraoperative pain in group M were significantly lower compared to group S. In addition, the incidence of rescue epidural administration of fentanyl (18% vs 47%) or mepivacaine (2.3% vs 25%) for intraoperative pain was lower in group M compared to group S. CONCLUSIONS Our results indicate that epidural administration of 2% mepivacaine 20 minutes after spinal anesthesia does not reduce the incidence of IONV in CS under CSEA. However, intraoperative epidural administration of 2% mepivacaine was found to improve intraoperative pain.

[PMID: 36620101 PMCID: PMC9813993 DOI: 10.4103/aer.aer_86_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 09/10/2022] [Accepted: 09/16/2022] [Indexed: 12/13/2022] Open
Abstract
Background Nausea and vomiting (NV) seen during and after lower segment cesarean section (LSCS) are due to increased intragastric pressure, hypotension, stretching the peritoneum (exteriorization of the uterus), excessive surgical manipulation and visceral stimulation, using opioids, using uterotonic agents, and the patient's mental status. Ondansetron and granisetron intravenous (i.v.) are useful for avoiding bradycardia and hypotension. Objectives The objective of this study is to study the effectiveness of granisetron versus ondansetron to control NV during LSCS under subarachnoid block. Materials and Methods Eighty patients undergoing elective cesarean section under spinal anesthesia by intrathecal bupivacaine were randomly divided into two groups (40 pregnant females of the American Society of Anesthesiologists physical status Classes I and II in each Group). Group 1 received granisetron 40 mg.kg-1 i.v. stat after clamping the cord and Group 2 given i.v. ondansetron 8 mg stat after clamping the cord. NV were observed at the "early postoperative period (0-3 h)" and "late postoperative period (4-24 h)." Statistical Analysis Used Student's t-test and Chi-square test were used to find out the statistical significance, P < 0.05 was considered statistically significant. Results The mean age was 29.3 years with 4.15 standard deviation (SD) and 28.3 years with 4.41 SD in Groups 1 and 2, respectively. The mean duration of surgery was 53.1 min with 6.67 min SD and 57.7 min with 10.26 SD in Groups 1 and 2, respectively. In the "early postoperative period," NV observed in 7.5% and 10.0% participants in Groups 1 and 2, respectively (P > 0.05), and in "late postoperative period," NV observed in 0.0% and 22.5% participants in Groups 1 and 2, respectively (P < 0.05). Conclusion Granisetron reduces the severity of spinal-induced hypotension, need for rescue vasopressor, and incidence of nausea.

[PMID: 35607304 PMCID: PMC9124121 DOI: 10.1155/2022/1681803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 04/19/2022] [Accepted: 04/20/2022] [Indexed: 11/17/2022]
Abstract
Objective. To evaluate the anesthetic effect and safety of dexmedetomidine in cesarean section. Methods. The Cochrane Library, EMBASE, and PubMed databases (established until September 2020) were searched by computer. Two authors independently screened and extracted literature related to the application of dexmedetomidine in the cesarean section according to inclusion and exclusion criteria. The control group received either subarachnoid block (lumbar anesthesia) or combined lumbar anesthesia and epidural anesthesia (combined lumbar epidural anesthesia) with bupivacaine or combined bupivacaine and fentanyl. The observation group was additionally given dexmedetomidine based on the control group, to analyze the anesthetic effect and safety of dexmedetomidine in cesarean section. Results. A total of 580 cesarean delivery women were included in 8 studies, and the results showed that the peak time of sensory block in the observation group was shorter than that in the control group (standard mean
; 95% confidence interval: -0.48, -0.08;
), sensory block lasted longer than that in the control group (standard mean
; 95% confidence interval: 1.21, 1.78;
), the sedation rate was higher than that in the control group, the onset of the first postoperative pain was significantly delayed compared with that in the control group, and the incidence of postoperative pain, nausea and vomiting, postoperative chills, and fever was lower than that in the control group (
). Conclusion. Dexmedetomidine combined with lumbar anesthesia or combined lumbar epidural anesthesia for women in cesarean section has more clinical benefits and better safety.

Metoclopramide and Propofol to Prevent Nausea and Vomiting during Cesarean Section under Spinal Anesthesia: A Randomized, Placebo-Controlled, Double-Blind Trial. J Clin Med 2021; 11:jcm11010110. [PMID: 35011852 PMCID: PMC8745529 DOI: 10.3390/jcm11010110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/20/2021] [Accepted: 12/24/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Intra-operative nausea, vomiting and retching (NVR) are frequently associated with subarachnoid anesthesia (SA) in women undergoing cesarean section (CS). In this study performed in women undergoing CS under SA with a risk factor control strategy, we compared saline (placebo), propofol, metoclopramide and both drugs to prevent NVR. Methods: We recorded NVR events in 110 women undergoing CS who were randomized after umbilical cord clamping to receive saline (S; n = 27), metoclopramide 10 mg (M; n = 28), propofol 1 mg/kg/h (P; n = 27) or both drugs (PM; n = 28). Results: The proportion of women with intra-operative nausea was: S: 17/27 (63%); P: 15/27 (56%); M: 13/28 (46%); PM: 6/28 (21%) (p = 0.012, Cramér’s V = 0.31 (large effect). The proportion of women with intra-operative vomiting/retching was: S: 9/27 (33%); M: 7/27 (25%); P: 3/28 (11%); PM 2/28 (7%) (p = 0.049, Cramér’s V = 0.26 (medium effect). Post-hoc multiple comparisons revealed a significant reduction in NVR episodes and NRS scores between the PM group and control. Sedation scores did not differ among groups. Conclusion: In women undergoing CS under SA with a risk factor control strategy, combined propofol and metoclopramide reduce nausea and vomiting.

Abstract
PURPOSE We conducted an updated systematic review and meta-analysis on maternal outcomes associated with uterine exteriorization compared with in situ repair in women undergoing Cesarean delivery. METHODS We searched for randomized controlled trials comparing uterine exteriorization with in situ repair during Cesarean delivery. Primary outcomes were intraoperative nausea and vomiting (IONV) and perioperative decrease in hemoglobin concentration. Secondary outcomes were postoperative nausea and vomiting (PONV), estimated blood loss, fever, endometritis, wound infection, intraoperative and postoperative pain, postoperative analgesic use, duration of surgery and hospital stay, and time to return of bowel function. RESULTS Twenty studies with 20,909 parturients were included. Exteriorization was associated with higher risk of IONV (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.66 to 2.63; I2 = 0%), with no difference in perioperative hemoglobin concentration decrease (mean difference, - 0.06 g·dL-1; 95% CI, - 0.20 to 0.08; I2 = 97%) compared with in situ repair. There were no significant differences in estimated blood loss, transfusion requirement, PONV, duration of surgery, duration of hospital stay, time to return of bowel function, fever, endometritis, or wound infection. Postoperative pain (incidence of pain graded > 5/10) at six hours (OR, 1.64; 95% CI, 1.31 to 2.03; I2 = 0%) was higher with exteriorization, but there was no difference in need for rescue analgesia (OR, 2.48; 95% CI, 0.89 to 6.90; I2 = 94%) or pain scores at 24 hr compared with in situ repair. CONCLUSIONS In this updated systematic review and meta-analysis, uterine exteriorization was associated with an increased risk of IONV but no significant change in perioperative hemoglobin decrease compared with in situ repair.

Abstract
BACKGROUND Intraoperative nausea and vomiting are common intraoperative events by which parturient feel discomfort and disturbed after spinal anesthesia. METHODS Hospital-based cross-sectional study was conducted on mothers who underwent cesarean section with spinal anesthesia. Descriptive analysis and chi-square test were employed. Bivariable and multivariable logistic regressions were used to measure the association of factors with the outcome variable intraoperative nausea and vomiting. A p-value of ≤0.05 was used to decide statistical significance for multivariable logistic regression. RESULT A total of 246 parturients were participated in this study. The incidence of intraoperative nausea and vomiting was 40.2%. According to multivariable logistic regression, age greater than 30 years (AOR, 6.26; 95%CI, 2.2-17.78; p-value 0.001), primiparous (AOR, 3.72; 95%CI, 1.35-10.24; p-value, 0.011), having motion sickness (AOR, 7.1; 95%CI, 2.75-18.33; p-value 0.001), emergency cesarean sectin (AOR, 9.85; 95%CI, 3.19-30.38; p-value 0.001), oxygen suplimentation (AOR, 0.021; 95%CI, 0.005-0.08; p-value 0.0001) and uterotonic agent (AOR, 2.99; 95%CI 1.24-7.22; p-value 0.015) had statistically significant association with intraoperative nausea and vomiting. CONCLUSION In our study, the overall incidence of intraoperative nausea and vomiting after spinal anesthesia was 40.2%. Parturients with age greater than 30 years, having motion sickness, didn't get intraoperative supplemental oxygen, oxytocin used for the uterotonic purpose, emergency surgery, and primiparous were at increased risk of intraoperative nausea and vomiting.

Abstract
BACKGROUND Nausea and vomiting are distressing symptoms which are experienced commonly during caesarean section under regional anaesthesia and in the postoperative period. OBJECTIVES: To assess the efficacy of pharmacological and non-pharmacological interventions versus placebo or no intervention given prophylactically to prevent nausea and vomiting in women undergoing regional anaesthesia for caesarean section. SEARCH METHODS For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (16 April 2020), and reference lists of retrieved studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) of studies and conference abstracts, and excluded quasi-RCTs and cross-over studies. DATA COLLECTION AND ANALYSIS Review authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. Our primary outcomes are intraoperative and postoperative nausea and vomiting. Data entry was checked. Two review authors independently assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS Eighty-four studies (involving 10,990 women) met our inclusion criteria. Sixty-nine studies, involving 8928 women, contributed data. Most studies involved women undergoing elective caesarean section. Many studies were small with unclear risk of bias and sometimes few events. The overall certainty of the evidence assessed using GRADE was moderate to very low. 5-HT3 antagonists: We found intraoperative nausea may be reduced by 5-HT3 antagonists (average risk ratio (aRR) 0.55, 95% confidence interval (CI) 0.42 to 0.71, 12 studies, 1419 women, low-certainty evidence). There may be a reduction in intraoperative vomiting but the evidence is very uncertain (aRR 0.46, 95% CI 0.29 to 0.73, 11 studies, 1414 women, very low-certainty evidence). There is probably a reduction in postoperative nausea (aRR 0.40, 95% CI 0.30 to 0.54, 10 studies, 1340 women, moderate-certainty evidence), and these drugs may show a reduction in postoperative vomiting (aRR 0.47, 95% CI 0.31 to 0.69, 10 studies, 1450 women, low-certainty evidence). Dopamine antagonists: We found dopamine antagonists may reduce intraoperative nausea but the evidence is very uncertain (aRR 0.38, 95% CI 0.27 to 0.52, 15 studies, 1180 women, very low-certainty evidence). Dopamine antagonists may reduce intraoperative vomiting (aRR 0.41, 95% CI 0.28 to 0.60, 12 studies, 942 women, low-certainty evidence) and postoperative nausea (aRR 0.61, 95% CI 0.48 to 0.79, 7 studies, 601 women, low-certainty evidence). We are uncertain if dopamine antagonists reduce postoperative vomiting (aRR 0.63, 95% CI 0.44 to 0.92, 9 studies, 860 women, very low-certainty evidence). Corticosteroids (steroids): We are uncertain if intraoperative nausea is reduced by corticosteroids (aRR 0.56, 95% CI 0.37 to 0.83, 6 studies, 609 women, very low-certainty evidence) similarly for intraoperative vomiting (aRR 0.52, 95% CI 0.31 to 0.87, 6 studies, 609 women, very low-certainty evidence). Corticosteroids probably reduce postoperative nausea (aRR 0.59, 95% CI 0.49 to 0.73, 6 studies, 733 women, moderate-certainty evidence), and may reduce postoperative vomiting (aRR 0.68, 95% CI 0.49 to 0.95, 7 studies, 793 women, low-certainty evidence). Antihistamines: Antihistamines may have little to no effect on intraoperative nausea (RR 0.99, 95% CI 0.47 to 2.11, 1 study, 149 women, very low-certainty evidence) or intraoperative vomiting (no events in the one study of 149 women). Antihistamines may reduce postoperative nausea (aRR 0.44, 95% CI 0.30 to 0.64, 4 studies, 514 women, low-certainty evidence), however, we are uncertain whether antihistamines reduce postoperative vomiting (average RR 0.48, 95% CI 0.29 to 0.81, 3 studies, 333 women, very low-certainty evidence). Anticholinergics: Anticholinergics may reduce intraoperative nausea (aRR 0.67, 95% CI 0.51 to 0.87, 4 studies, 453 women, low-certainty evidence) but may have little to no effect on intraoperative vomiting (aRR 0.79, 95% CI 0.40 to 1.54, 4 studies; 453 women, very low-certainty evidence). No studies looked at anticholinergics in postoperative nausea, but they may reduce postoperative vomiting (aRR 0.55, 95% CI 0.41 to 0.74, 1 study, 161 women, low-certainty evidence). Sedatives: We found that sedatives probably reduce intraoperative nausea (aRR 0.65, 95% CI 0.51 to 0.82, 8 studies, 593 women, moderate-certainty evidence) and intraoperative vomiting (aRR 0.35, 95% CI 0.24 to 0.52, 8 studies, 593 women, moderate-certainty evidence). However, we are uncertain whether sedatives reduce postoperative nausea (aRR 0.25, 95% CI 0.09 to 0.71, 2 studies, 145 women, very low-certainty evidence) and they may reduce postoperative vomiting (aRR 0.09, 95% CI 0.03 to 0.28, 2 studies, 145 women, low-certainty evidence). Opioid antagonists: There were no studies assessing intraoperative nausea or vomiting. Opioid antagonists may result in little or no difference to the number of women having postoperative nausea (aRR 0.75, 95% CI 0.39 to 1.45, 1 study, 120 women, low-certainty evidence) or postoperative vomiting (aRR 1.25, 95% CI 0.35 to 4.43, 1 study, 120 women, low-certainty evidence). Acupressure: It is uncertain whether acupressure/acupuncture reduces intraoperative nausea (aRR 0.55, 95% CI 0.41 to 0.74, 9 studies, 1221 women, very low-certainty evidence). Acupressure may reduce intraoperative vomiting (aRR 0.52, 95% CI 0.33 to 0.80, 9 studies, 1221 women, low-certainty evidence) but it is uncertain whether it reduces postoperative nausea (aRR 0.46, 95% CI 0.27 to 0.75, 7 studies, 1069 women, very low-certainty evidence) or postoperative vomiting (aRR 0.52, 95% CI 0.34 to 0.79, 7 studies, 1069 women, very low-certainty evidence). Ginger: It is uncertain whether ginger makes any difference to the number of women having intraoperative nausea (aRR 0.66, 95% CI 0.36 to 1.21, 2 studies, 331 women, very low-certainty evidence), intraoperative vomiting (aRR 0.62, 95% CI 0.38 to 1.00, 2 studies, 331 women, very low-certainty evidence), postoperative nausea (aRR 0.63, 95% CI 0.22 to 1.77, 1 study, 92 women, very low-certainty evidence) and postoperative vomiting (aRR 0.20, 95% CI 0.02 to 1.65, 1 study, 92 women, very low-certainty evidence). Few studies assessed our secondary outcomes including adverse effects or women's views. AUTHORS' CONCLUSIONS This review indicates that 5-HT3 antagonists, dopamine antagonists, corticosteroids, sedatives and acupressure probably or possibly have efficacy in reducing nausea and vomiting in women undergoing regional anaesthesia for caesarean section. However the certainty of evidence varied widely and was generally low. Future research is needed to assess side effects of treatment, women's views and to compare the efficacy of combinations of different medications.

Abstract
OBJECTIVE To investigate whether continuous infusion of propofol at a subhypnotic dose prevents nausea and vomiting following carboprost administration at cesarean delivery. METHODS A prospective, randomized, double-blind, placebo-controlled trial conducted at West China Second University Hospital, from June 28, 2017 to January 30, 2018. Pregnant women were randomly allocated to propofol or saline infusion immediately before receiving carboprost at cesarean delivery under combined spinal-epidural (CSE) anesthesia. Propofol was given at an infusion rate of 1.0 mg/kg/h following a loading dose of 0.3 mg/kg. Primary outcome was incidence of intraoperative nausea and vomiting (IONV). Potential sedative effect of propofol infusion was assessed using Modified Observer's Assessment of Alertness and Sedation (MOAA/S) scoring and continuous Bispectral Index (BIS) monitoring. RESULTS The incidence of IONV was lower in patients who received propofol compared with saline (46.7% vs 76.7%, OR 0.27; 95% CI, 0.092-0.78, P = 0.016 for nausea; 26.7% vs 53.3%, OR 0.50; 95% CI, 0.25-0.95, P = 0.032 for retching; 10.0% vs 50.0%, OR 0.11; 95% CI, 0.03-0.44, P < 0.001 for vomiting). There were no differences in MOAA/S scoring or BIS between the two groups. CONCLUSION A subhypnotic dose of propofol reduces the incidence of nausea and vomiting following carboprost administration at cesarean delivery under CSE anesthesia, without measurable effect on patients' consciousness or alertness.

Abstract
AIM To measure the changes in cerebral oxygenation indices by near infrared time-resolved spectroscopy and the cerebral blood flow simultaneously after spinal anesthesia for cesarean section. METHODS This prospective observational study was conducted for 25 pregnant women scheduled for elective cesarean section under spinal anesthesia. During a period of 15 min after spinal anesthesia, cerebral oxygenation (ScO2 ), and the total cerebral hemoglobin concentration (tHb) were measured using near infrared time-resolved spectroscopy and mean cerebral blood flow velocity (Vm) was measured using transcranial Doppler ultrasonography. Next, in the women who had nausea during the observed period, we compared these values when nausea was detected with those when it was not. RESULTS Mean arterial pressure (MAP) decreased to around 60 mmHg (by 25% compared to the control) 6 min after spinal anesthesia. Compared to the control, ScO2 decreased by about 3% after 6 min and then gradually increased. The tHb, which reflects cerebral blood volume started to decrease just after spinal anesthesia and this continued until 12 min (the decrease was about 12%). Vm decreased by about 7%. In the 14 women who had nausea, MAP, Vm, and ScO2 values when nausea was detected were significantly lower than when it was not. CONCLUSION The changes in cerebral hemodynamics may be small after spinal anesthesia in ordinary cesarean section compared to the reduction of systemic arterial blood pressure. There might be greater decreases in cerebral blood flow and oxygenation when nausea occurred in the pregnant women who experienced it after spinal anesthesia.

Abstract
Nausea and vomiting are some of the most common complaints of patients after any anesthesia, which is often associated with postoperative pain. The double-blind clinical trial study aimed to compare the prophylactic effect of dexamethasone and dexmedetomidine and their combination in reducing postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy. One hundred sixty-two patients undergoing laparoscopic cholecystectomy were enrolled in the study. In the first group of patients, 25 mg of dexmedetomidine were administered slowly. In comparison, the patients in the second group received dexamethasone (4 ml/2 mg) with 0.1 mg/kg of normal saline solution. The third group received a combination of dexmedetomidine and dexamethasone. Hemodynamic changes were recorded during surgery and after surgery, and the patients were admitted to recovery. Nausea and vomiting scores were recorded 2 and 4 hours after surgery. Blood pressure and heart rate were lower in the dexmedetomidine group at all times (P<0.05). Two hours after surgery, the dexamethasone and dexmedetomidine combination group had less vomiting (P=0.012). The incidence of nausea 2 and 4 hours after surgery was lower in the dexamethasone and dexmedetomidine combination group (P<0.05). Blood pressure and heart rate were lower in the dexmedetomidine group at all times. The dexmedetomidine and dexamethasone combination decreased postoperative nausea and vomiting in patients. Therefore, we recommend using a dexmedetomidine and dexamethasone combination for reducing postoperative nausea and vomiting.

Effects of colloid preload on the incidence of hypotension in spinal anesthesia for cesarean section: a systematic review and meta-analysis. Chin Med J (Engl) 2021; 134:1043-1051. [PMID: 33883404 PMCID: PMC8116017 DOI: 10.1097/cm9.0000000000001477] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/29/2022] Open
Abstract
Background: Hypotension is a common complication caused by spinal anesthesia (SA), which may have adverse impacts on the condition of the parturient and fetus. Liquid infusion was found to be relatively effective for reducing the incidence of hypotension. However, the question of whether colloid preload can optimize hemodynamic variables in the cesarean section remains controversial. This study aims to determine the effects of colloid preload on the incidence of hypotension induced by SA in elective cesarean section. Methods: Related keywords were searched on PubMed, EMBASE, and Cochrane Library from inception dates to May 2020. Studies included were evaluated for eligibility and quality. The primary outcome was the intra-operative incidence of hypotension and severe hypotension. The secondary outcomes included the lowest intra-operative systolic blood pressure, the maximal intra-operative heart rate, the intra-operative needs of ephedrine and phenylephrine, the incidence of maternal nausea and/or vomiting, and neonatal outcomes (umbilical artery pH and Apgar scores). Apart from the above, RevMan 5.3 was used for the data analysis. Results: Altogether nine randomized controlled trials were included in the meta-analysis. There were no significant differences in the incidence of intra-operative hypotension, severe hypotension, or neonatal outcomes between the colloid preload group and control group, except for the umbilical artery pH. Conclusion: This meta-analysis suggests that colloid preload does not significantly reduce the incidence of hypotension associated with SA in elective cesarean section.

Implications of Continuous Noninvasive Finger Cuff Arterial Pressure Device Use during Cesarean Delivery for Goal-Directed Fluid Therapy Preload Optimization: A Randomized Controlled Trial. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6685584. [PMID: 33855080 PMCID: PMC8019625 DOI: 10.1155/2021/6685584] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 03/12/2021] [Accepted: 03/18/2021] [Indexed: 11/17/2022]
Abstract
Background Although fixed-volume conventional fluid preloading protocol fails to attenuate postspinal hypotension during cesarean delivery, the effect of goal-directed fluid therapy (GDFT) remains less explored. Continuous noninvasive finger cuff arterial pressure monitoring using devices such as the ClearSight System can provide the noninvasive stroke volume value, enabling clinicians to perform GDFT before spinal anesthesia; however, the efficacy of GDFT requires further elucidation. Method In total, 71 consecutive full-term pregnant women were randomly divided into a control group (n = 34) and a GDFT group (n = 37). Before spinal anesthesia, the control group received a fixed dose (1000 mL) of crystalloid fluid, but the GDFT group received repeated 3 mL/kg body weight of crystalloid fluid challenges within 3 minutes with a 1-minute interval between each fluid challenge based on the stroke volume incremental changes obtained using the ClearSight System (targeting a stroke volume increase of ≥5% after a fluid challenge). The primary outcome was the incidence of postspinal hypotension. The secondary outcomes were total fluid volume, vasopressor dosage, hemodynamic parameter changes, maternal adverse effects, and neonatal profiles. Result Women in the GDFT group received more fluid than did those in the control group (1132 ± 108 vs. 1247 ± 202 mL; p = 0.0044), but the incidence of postspinal hypotension (79.4% vs. 73.0%,; p = 0.5864) and norepinephrine dose (12.5 ± 10.6 vs. 15.1 ± 12.8 mcg, respectively; p = 0.3512) was comparable between the two groups. Fewer women in the GDFT group experienced nausea (61.76% vs. 35.14%; p = 0.0332). Neonatal outcomes (Apgar score and umbilical blood analysis) were comparable and typical in both groups. Conclusion ClearSight-guided GDFT did not ameliorate postspinal hypotension but may reduce nausea. This trial is registered with NCT03013140.

Abstract
BACKGROUND Maternal hypotension is the most frequent complication of spinal anesthesia for cesarean delivery, and intravenous fluid preloading is a preventive measure. We aimed to assess the efficacy of colloids versus crystalloids for preloading to reduce the incidence of spinal anesthesia-induced hypotension and vasopressor requirement in healthy parturients during elective cesarean delivery. METHODS We searched the Cochrane Library, MEDLINE and EMBASE to identify all studies published to June, 2019, through OVID and PubMed. We included randomized controlled trials, comparing colloid preloading with crystalloid preloading in women having spinal anesthesia for cesarean delivery. Primary outcomes were the incidence of hypotension and vasopressor requirement. Secondary outcomes included nausea and/or vomiting, neonatal Apgar score, neonatal umbilical blood pH. We used standardized mean differences for expressing continuous outcomes and risk ratios for dichotomous outcomes. Random-effect model was performed to estimate the pooled risk ratios and standardized mean differences. RESULTS Thirty-three randomized controlled trials contributed data for this meta-analysis. Fewer women experienced hypotension in the colloid group compared with the crystalloid group (risk ratio: 0.72, 95% confidence interval: 0.63-0.82; 2566 women, 32 studies; P < .00001). The total ephedrine dose required was significantly lower with colloid preloading (standardized mean difference: -0.37, 95% CI: -0.64 to -0.09; 1472 women, 19 studies; P = .009). Colloid preloading was also associated with fewer phenylephrine requirement compared with crystalloid preloading (standardized mean difference: -0.54, 95% CI: -0.82 to -0.25; 169 women; P = .0002). The incidence of nausea and/or vomiting was significantly reduced with colloid preloading (risk ratio: 0.72, 95% CI: 0.55-0.95; 1601 women, 20 studies; P = .02). However, the incidence of 1-minute Apgar score < 7, umbilical artery pH < 7.2 and umbilical vein pH < 7.2 were not statistically different between groups. CONCLUSIONS Colloid preloading is superior to crystalloid preloading in reducing the incidence of hypotension induced by spinal anesthesia and vasopressor requirement in the healthy parturients undergoing elective cesarean delivery.The PROSPERO registration number: CRD42018096402.

Abstract
INTRODUCTION Adequate pain control is a mainstay in enhanced recovery after surgery (ERAS) protocols. ERAS protocols are widely accepted in colorectal and gynecologic surgeries and are increasingly implemented in the obstetric setting. Multimodal analgesia incorporating non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen is a mainstay of ERAS protocols for cesarean delivery, but little research has focused on the choice of NSAIDs or timing of initiation in women undergoing cesarean delivery. At our institution, patients undergoing cesarean delivery receive a standardized multimodal analgesic regimen consisting of neuraxial morphine with NSAIDs and acetaminophen. Our initial protocol involved starting the oral analgesics in the recovery room. There was variability in whether these medications were given in a timely manner or withheld in the setting of postoperative nausea and vomiting. We modified this protocol and performed a retrospective analysis to assess the impact of this change on postoperative opioid rescue requirements in women undergoing cesarean delivery under neuraxial anesthesia. METHODS This retrospective analysis included patients who underwent cesarean deliveries from 1 July 2014 to 22 August 2017. With the initial analgesic protocol, patients received neuraxial morphine, followed by naproxen 500 mg PO Q12 hours and acetaminophen 650-975 mg PO Q6 hours initiated in the recovery room. After protocol revision in January 2016, the same neuraxial morphine dose was used in addition to acetaminophen 975 mg PR at the start of the case and ketorolac 15-30 mg IV at the end of the case. Postoperatively, patients received acetaminophen PO 975 mg Q6 hours, ketorolac IV 15 mg Q6 hours for 3 doses, transitioning to ibuprofen 600 mg Q6 hours. Fentanyl, oxycodone, and intravenous hydromorphone were given for breakthrough pain with both protocols. The primary outcome of the study is the need for rescue opioid analgesia. Secondary outcomes are total opioid usage, time to first rescue opioid, maximum reported pain scores, and need for rescue antiemetics. Univariate and multivariate analyses were performed controlling for variables significantly different between the two cohorts. RESULTS 3250 patients were included in our analysis (1574 in the old protocol and 1676 in the new protocol). There was no significant difference in patient demographics or intraoperative characteristics between the two cohorts except for more primiparous women (25% vs. 17%), more Pfannenstiel incision (98% vs. 96%), and less repeat cesarean deliveries (40% vs. 44%) in the new protocol cohort. Need for rescue opioids was reduced with the new protocol at 2, 24, and 48 h [(36.46% vs. 75.73%, p < .0001), (74.28% vs 91.99%, p < .0001), (87.53% vs 95.49% p < .0001), respectively]. Among those who received opioids, opioid consumption over 48 h was reduced (median [IQR]: 55 [30, 95] vs. 40 [20, 70] mg oxycodone equivalents) after protocol revision (GMR 0.75, 95% CI 0.7, 0.80, p < .0001). The time to first rescue opioid medication was significantly longer in the new protocol compared to the old protocol (175 [79, 1057] min vs 51 [28, 104] min, p < .001). CONCLUSION There was a significant decrease in the need for and the dose of rescue opioid medications with the new protocol. This highlights the importance of optimizing the choice of agents, as well as route and timing of administration of the components of the postoperative multimodal analgesic regimen.

Abstract
Purpose Carboprost may induce adverse reactions when used to treat postpartum hemorrhage. We aimed to explore the effects of intravenous infusion of low-dose remifentanil to prevent such reactions. Methods We enrolled parturient patients scheduled for elective cesarean section. Anesthesiologist administered combined spinal epidurals at the L3/4 interspace, with 0.5% hyperbaric bupivacaine subarachnoid space injections (1.5–2.5 ml). We randomly divided parturient patients, administered carboprost during surgery, into the remifentanil group (group R) and the control group (group C). Patients in group R received an intravenous target-controlled infusion of remifentanil (target effect-site concentration, 1.5 ng/ml) simultaneously with a carboprost tromethamine injection (250 µg). Patients in group C received a normal saline infusion with carboprost. We recorded and analyzed the incidence of carboprost-related adverse reactions (vomiting, nausea, chest congestion, flushing, hypertension, tachycardia, cough, and shivering), and assessed patient comfort using a numerical rating scale ([NRS], on which 0 was very uncomfortable and 10 was very comfortable). Results After applying inclusion and exclusion criteria, we conducted statistical analysis of the data from 70 women. The incidence of vomiting was significantly lower in group R than in group C (14.3 vs. 51.4%, p < 0.01); and the incidence of nausea, chest congestion, facial flushing, and hypertension were significantly lower in group R than in group C (all p < 0.01). Furthermore, the patients’ comfort scores were significantly higher in group R than in group C (8.0 ± 1.8 vs. 3.6 ± 2.1, p < 0.01). Conclusion Our results demonstrate that an intravenous low-dose remifentanil infusion can effectively prevent carboprost-related adverse reactions during cesarean delivery under combined spinal and epidural anesthesia. Clinical Trial Registration We pre-registered this study at http://www.chictr.org.cn/showproj.aspx?proj=27707 (ChiCTR1800016292).

Abstract
BACKGROUND Intrathecal morphine (ITM) is a widely used technique for postcaesarean section analgesia but entails a high risk of postoperative nausea and vomiting (PONV). The transversus abdominis plane (TAP) block is an alternative. OBJECTIVE We tested the hypothesis that a TAP block including clonidine reduces the incidence of PONV after caesarean section when compared with ITM. DESIGN A randomised, controlled, double-blinded study. SETTING Geneva University Hospitals, Switzerland, from October 2013 to February 2017. PATIENTS A total of 182 patients undergoing elective caesarean section were studied. Reasons for noninclusion were complicated pregnancy, contraindication to spinal anaesthesia or TAP block, extreme weight or height, allergy to any medication or previous median abdominal incision. INTERVENTIONS Patients were allocated randomly to one of two groups (quadruple blinded): 100 μg of morphine added to the spinal local anaesthetic or a bilateral TAP block with 20 ml of ropivacaine 0.375% + 75 μg of clonidine on each side. MAIN OUTCOME MEASURES The primary outcome measure was the total number of patients presenting with PONV at 24 h. Secondary aims were to compare other adverse effects (pruritus, respiratory depression, hypotension, bradycardia, sedation), analgesic efficacy and the quality of postoperative recovery. RESULTS At 24 h, there was no significant difference between ITM and TAP groups in the total number of patients presenting with PONV: 17/92 patients (18.5%, 95% confidence interval 11.1 to 27.9) and 27/88 patients (30.7%, 95% confidence interval 21.3 to 41.4) in TAP and ITM groups, respectively (P = 0.065). Pain scores at 6 h and cumulative morphine consumption at 24 h were lower in the ITM group (P < 0.0001 for morphine consumption at 24 h). The incidence of hypotension was higher in the TAP group (54.3 vs. 29.2%, P = 0.0006). Maternal satisfaction was high and not different between groups. CONCLUSION A TAP block with clonidine and local anaesthetic does not reduce significantly the incidence of PONV compared with ITM. We confirm the superiority of ITM on acute postcaesarean section analgesia compared with a TAP block, even with clonidine as an adjunct. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT01931215.

Abstract
Intraoperative and postoperative nausea and vomiting (IONV and PONV) afflict up to 80% of parturients undergoing cesarean delivery with neuraxial anesthesia. Preventing nausea and emesis is a top priority for women undergoing cesarean delivery and is included in the quality of recovery measures and enhanced recovery after cesarean delivery protocols. The majority of known perioperative emetic triggers can be avoided or mitigated by optimizing anesthetic and surgical management. IONV may arise from spinal anesthesia-induced hypotension, intraoperative pain, and medications such as uterotonics and antibiotics. Furthermore, uterine exteriorization and peritoneal irrigation increase IONV risk. Conversely, preventing PONV mainly focuses on optimizing analgesia through an opioid-sparing, multimodal strategy. In addition, combination prophylactic antiemetic therapy should be instituted in this high-risk population to further reduce the risk of IONV and PONV.

Abstract
Nausea is a mental sensation of unease and discomfort before vomiting. Vomiting refers to the return of the contents of the upper gastrointestinal tract to the mouth caused by contractions of chest and abdomen muscles. Postoperative nausea and vomiting is an unpleasant experience with high treatment costs. Therefore, this study aimed to compare the effects of haloperidol, metoclopramide, dexmedetomidine, and ginger on postoperative nausea and vomiting after laparoscopy. This double-blind clinical trial was performed on all laparoscopy candidates at Valiasr hospital, Arak, Iran. The patients were randomly divided into four groups (haloperidol, metoclopramide, dexmedetomidine and ginger), and all patients underwent general anesthesia using fentanyl, midazolam, atracurium, and propofol. After intubation, tube fixation, and stable hemodynamic conditions, the patients received four ginger capsules with a hint of lemon. A group of patients received 25 μg of dexmedetomidine. In the Plasil group, 10 mg of metoclopramide was given 30 minutes before the completion of surgery. In addition, 0.5 cc of haloperidol (5 mg) was administered to a group of patients. Heart rate, blood pressure, and oxygen saturation were recorded from the beginning of surgery, every 15 minutes until the end of the surgery. Furthermore, the occurrence of nausea and vomiting was recorded during recovery, 2 and 4 hours after surgery. Data were then analyzed using the SPSS software v.23. Eighty-eight patients were enrolled in the study. The youngest and the oldest were 30 years and 70 years old, respectively, and the mean age was 48.02 ± 9.31 years. Moreover, the number of women in the four groups was higher than that of men. Blood pressure in the dexmedetomidine group was lower than the other four groups (P <0.05). The lowest heart rate was observed in the haloperidol group, while the highest heart rate was seen in the plasil group (P <0.05). The occurrence of vomiting and nausea was not significantly different between the four groups (P <0.05). Our results showed no significant difference in postoperative nausea and vomiting between the four drugs. Due to the hemodynamic changes induced by each drug, it is best to use these drugs based on the patient's condition. Ginger is also a herbal remedy that has fewer side effects, and this drug can be a good option for patients when there is no contraindication.

Abstract
The number of caesarean sections performed worldwide is increasing, and with it, the need for the optimal analgesia strategies. Deficient postoperative analgesia increases the need for opioids, delays recovery, and is associated with chronic pain and postpartum depression. It is essential to find good postoperative pain control strategies that facilitate early mobility, early recovery, and early hospital discharge with minimal side effects on the mother and infant. Multimodal analgesia based on neuroaxial anaesthesia with morphine in combination with non-opioids such as non-steroidal anti-inflammatory drugs and paracetamol, gives the best post-caesarean analgesia outcome, and allows anaesthesiologists to reserve opioids, corticoids, gabapentin, magnesium or ketamine for situations where neuroaxial anaesthesia cannot be performed, for high-risk patients, or when pain is difficult to control. Peripheral nerve block techniques can also be added, such as transverse abdominis plane block, erector spinae block, or continuous wound infiltration.

Abstract
Spinal hypotension is a common and clinically important problem during caesarean section. Current consensus recommendations for resource-rich settings suggest the use of a titrated phenylephrine infusion, in combination with fluid coloading, for prevention of maternal hypotension. In resource-limited settings, where syringe drivers are unavailable, these recommendations advise the addition of 500 μg phenylephrine to the first 1 l of intravenous fluid given after initiation of spinal anaesthesia, with additional vasopressor boluses as required. This prospective, alternating intervention study compared the use of a conventional phenylephrine rescue bolus strategy for prevention of hypotension, defined as systolic arterial pressure < 90 mmHg, with a phenylephrine infusion given according to the consensus recommendation. We studied 300 women having elective caesarean section. There were 77 (51%) women who developed hypotension in the bolus group vs. 55 (37%) in the phenylephrine infusion group (p = 0.011). This represented a 29% reduction in hypotension, with a number needed to treat of 6.8. The six highest systolic arterial pressure readings occurred in the phenylephrine infusion group (range 166-188 mmHg), and there were four instances of bradycardia (heart rate < 50 beats.min-1 ) with preserved systolic arterial pressure in each group. There were no adverse clinical sequelae, and no differences in neonatal Apgar scores in either group. The consensus recommendation for phenylephrine and fluid co-administration in resource-limited settings appears effective in preventing maternal hypotension, but at the cost of sporadic systolic hypertension.

Abstract
BACKGROUND This Enhanced Recovery After Surgery Guideline for postoperative care in cesarean delivery will provide best practice, evidenced-based recommendations for postoperative care with primarily a maternal focus. OBJECTIVE The pathway process for scheduled and unscheduled cesarean delivery for this Enhanced Recovery After Surgery cesarean delivery guideline will consider time from completion of cesarean delivery until maternal hospital discharge. STUDY DESIGN The literature search (1966-2017) used Embase and PubMed to search medical subject headings that included "Cesarean Section," "Cesarean Delivery," "Cesarean Section Delivery," and all postoperative Enhanced Recovery After Surgery items. Study selection allowed titles and abstracts to be screened by individual reviewers to identify potentially relevant articles. Metaanalyses, systematic reviews, randomized controlled studies, nonrandomized controlled studies, reviews, and case series were considered for each individual topic. Quality assessment and data analyses evaluated the quality of evidence, and recommendations were evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system as used and described in previous Enhanced Recovery After Surgery Guidelines. RESULTS The Enhanced Recovery After Surgery cesarean delivery guideline/pathway has created a pathway for postoperative care. Specifics include sham feeding, nausea and vomiting prevention, postoperative analgesia, nutritional care, glucose control, thromboembolism prophylaxis, early mobilization, urinary drainage, and discharge counseling. A number of elements of postoperative care of women who undergo cesarean delivery are recommended, based on the evidence. CONCLUSION As the Enhanced Recovery After Surgery cesarean delivery pathway (elements/processes) are studied, implemented, audited, evaluated, and optimized by the maternity care teams, there will be an opportunity for focused and optimized areas of care and recommendations to be further enhanced.

Abstract
Objective Although opioids may induce nausea and vomiting, they possess sedative effects and can reduce intraoperative nausea and vomiting (IONV). This study assessed the effect of adding fentanyl to midazolam on sedation levels and IONV during cesarean section under spinal anesthesia. Methods Eighty parturients scheduled for elective cesarean section were enrolled in the study. Following fetal delivery, patients were administered 0.05 mg/kg of midazolam plus 0.03 mL/kg of normal saline (M group) or 0.05 mg/kg of midazolam plus 1.5 μg/kg of fentanyl (MF group). The primary outcome was the incidence of IONV. The secondary outcomes were incidence of postoperative nausea and vomiting (PONV), intraoperative sedation level, and five-point patient satisfaction score (PSS). Results The IONV incidence was significantly lower in the MF group compared with the M group (5% [2/40] vs. 25% [10/40]). The PONV incidence did not differ significantly between the groups. The intraoperative sedation level tended to be deeper in the MF group. The 5-point PSS was significantly higher in the MF group. There was a strong correlation between the sedation level and IONV incidence. Conclusions Adding fentanyl to midazolam is effective for sedation and to prevent IONV in women who are undergoing cesarean section under spinal anesthesia.

Abstract
Objective Obstetric patients who receive combined spinal-epidural (CSE) anaesthesia for elective caesarean section (CS) frequently experience intraoperative nausea and vomiting (N&V). Prophylactic therapy with antiemetic agents can have multiple adverse effects to the mother and baby. We designed a randomised clinical trial to evaluate the efficacy of electrical P6 stimulation for prophylactic N&V treatment for scheduled elective CS performed under CSE anaesthesia. Methods Following the Institutional Review Board approval and informed consent, a total of 180 patients were randomly allocated into three groups: (1) P6 stimulation (via a peripheral nerve stimulator), (2) intravenous (IV) antiemetics (metoclopramide and ondansetron), and (3) control (no IV antiemetic medications and no P6 stimulation), with 60 parturients in each group. Results Significantly fewer patients experienced intraoperative N&V in the P6 group (nausea 36.7% and vomiting 13.3%) and IV antiemetic group (nausea 23.3% and vomiting 16.7%) than those in the control group (nausea 73.3% and vomiting 45%; p<0.001). In addition, significantly fewer patients required rescue antiemetic medications in the P6 group (35%) and the IV antiemetic group (31.7%) than those in the control group (73.3%; p<0.001). There was no significant difference in the overall anaesthetic care satisfaction reported between the three study groups. Conclusion Our data suggest that P6 stimulation is as simple and as effective as our routine prophylactic IV antiemetic treatment for prevention of N&V during CS performed under CSE anaesthesia that could be of great interest to patients and obstetric anaesthesiologists who prefer treatments with fewer potential side effects.

The Analgesic Efficacy of Transverse Abdominis Plane Block versus Epidural Block after Caesarean Delivery: Which One Is Effective? TAP Block? Epidural Block? Pain Res Manag 2018; 2018:3562701. [PMID: 30416635 PMCID: PMC6207903 DOI: 10.1155/2018/3562701] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Revised: 09/15/2018] [Accepted: 10/08/2018] [Indexed: 11/18/2022]
Abstract
Introduction and Objective TAP block has gained popularity to provide postoperative analgesia after abdominal surgery but its advantage over epidural analgesia is disputed. For lower abdominal surgeries, epidural analgesia has been the gold standard and time-tested technique for providing postoperative analgesia, but contraindications for the same would warrant need for other equally good analgesic techniques. The objective of this study is to compare the analgesic efficacy of both the techniques. Materials and Methods Eighty patients in the ASA I-II risk group, undergone an elective C-section, were randomly assigned to the study. In the TAP group, before the C-section, a single-dose spinal anaesthesia was performed by administering 3 ml of 0.5% hyperbaric bupivacaine to the patients when they were in the sitting position. After the C-section, an ultrasound-guided bilateral TAP block was performed in these patients in the recovery room for postoperative analgesia. In the single-dose EPI group, the patients received 16 cc of isobaric bupivacaine, 3 mg of morphine, and 50 mcg of fentanyl, making a total volume of 20 cc and being administered to the epidural space. Results A higher level of patient satisfaction was observed in the EPI group (p=0.003). The amount (mg) of total analgesics received by the patients in the first 24 hours of the postoperative period was statistically significantly higher (p=0.021) in the TAP group compared to the EPI group. The visual analogue scale (VAS) scores of the EPI group were significantly lower compared to that of the TAP group (p < 0.001). Conclusion The epidural anaesthesia is still the golden standard to achieve a postcaesarean analgesia. Epidural anaesthesia is a considerably effective method in controlling the postoperative pain. We are of the opinion that epidural anaesthesia should be preferred in the first place to achieve a successful postcaesarean analgesia as it provides more effective pain control.

Abstract
PURPOSE Nausea and vomiting are common, undesirable symptoms during cesarean section. We conducted this study to assess the antiemetic properties of propofol for the prevention and immediate treatment of post-delivery nausea and vomiting during cesarean section under combined spinal-epidural anesthesia. METHODS Eighty women undergoing elective cesarean delivery under combined spinal-epidural anesthesia were randomized to receive either propofol at a plasma concentration of 1000 ng/mL or normal saline immediately after clamping of the umbilical cord. The incidence of post-delivery nausea and vomiting, patients requiring rescue antiemetic, bispectral index, sedation score, and the incidence of hypotension were assessed intraoperatively. Satisfaction and neonatal behavioral neurological assessments were evaluated postoperatively. RESULTS The incidence of nausea was significantly lower in the propofol group compared to the placebo group (25% versus 60%, P < 0.001). The incidence of retching and vomiting showed no significant difference between the two groups. Propofol 20 mg as a rescue antiemetic was significantly effective in both the groups. Satisfaction level of patients and obstetricians in the propofol group was higher than in the placebo group. There was no statistical difference in the incidence of hypotension between the two groups both pre- and post-delivery. There was no difference in postoperative neonatal behavioral neurological assessment between groups. CONCLUSION Propofol at a plasma concentration of 1000 ng/mL significantly reduced the incidence of post-delivery nausea compared to placebo, but had no effect on reducing retching or vomiting episodes during cesarean section.
