Ni L, Yao S, Wu Y, Ni J, Wang Q, Mei Z, Yu J. Epidural dexmedetomidine or esketamine versus fentanyl to decrease ropivacaine use for labor analgesia: A randomized non-inferiority study. Heliyon 2024; 10:e30218. [PMID: 38707421 PMCID: PMC11066411 DOI: 10.1016/j.heliyon.2024.e30218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/18/2024] [Accepted: 04/22/2024] [Indexed: 05/07/2024] Open
Abstract
Background Epidural nonopioid adjuvants also reduce local anesthetic use. We aimed to test the hypothesis that, compared with the present standard fentanyl, the hourly consumption of local anesthetic was at least as good when dexmedetomidine or esketamine was combined with local anesthetic for patient-controlled epidural analgesia (PCEA). Methods A total of 120 laboring nulliparous subjects requiring labor analgesia were recruited for the final statistical analysis. Subjects were randomized to receive 0.075 % ropivacaine added with one of three equivalent adjuvants: 0.4 μg/mL fentanyl, 0.4 μg/mL dexmedetomidine, or 1.0 mg/mL esketamine. The primary outcome was hourly ropivacaine consumption. Compared with the fentanyl group, a 20 % difference in hourly local anesthetic consumption between the dexmedetomidine and esketamine groups was considered a clinical difference (non-inferiority margin). Results The hourly ropivacaine consumption of the fentanyl group was 12.4 (95 % confidence interval CI 11.2 to 13.6) ml/h, so the prespecified non-inferiority limit was 2.5 ml/h. The hourly ropivacaine consumption of the fentanyl group was not inferior to that of the dexmedetomidine group (12.4 ml/h vs. 11.9 ml/h, risk difference, 0.5; 95 % confidence interval CI, -1.0 to 2.0, meeting criteria for non-inferiority). However, the hourly ropivacaine consumption of the esketamine group was 14.3 ml/h, and that of the fentanyl group was 12.4 ml/h (risk difference, 1.9, 95 % CI, 0.2 to 3.6), failing to confirm non-inferiority with a non-inferiority margin of 20 %. The incidence of pruritus was highest in the fentanyl group, whereas the occurrence of mild dizziness was highest in the esketamine group. Conclusions In setting of the conditions of this study, epidural dexmedetomidine was non-inferior compared with epidural fentanyl in combination with ropivacaine for PCEA during labor. Meanwhile, we failed to establish the non-inferiority of epidural esketamine compared with epidural fentanyl in combination with ropivacaine for labor analgesia.

Perioper Med (Lond) 2024; 13:7. [PMID: 38355657 PMCID: PMC10868062 DOI: 10.1186/s13741-024-00363-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 01/31/2024] [Indexed: 02/16/2024] Open
Abstract
BACKGROUND This study was performed to analyze the clinical effect of different concentrations of ropivacaine in the labor analgesia of the dural puncture epidural (DPE) technique for obese puerperae. METHODS One hundred and fifty first-term obese women who received vaginal delivery and required labor analgesia in our hospital were selected prospectively for this study, and divided into groups A, B, and C. The three groups of puerpera were given epidurals with different concentrations of ropivacaine (0.075%, 0.10%, and 0.125%) with sufentanil (0.5 μg/ml) for the labor analgesia regimen. The visual analog scale (VAS), Ramsay scale, and Bromage scale of puerperae before analgesia and at different time points after anesthesia, and analgesic onset time, analgesia time, first PCEA time, PCEA pressing time, ropivacaine consumption, labor time, maternal blood pressure and heart rate, maternal adverse reactions, blood gas analysis in the neonatal umbilical artery, and Apgar score were observed. RESULTS The analgesia onset time, PCEA pressing time, and ropivacaine consumption in group C were lower and the analgesia time and the first PCEA time were longer than those in groups A and B. At T1-T3 and T5, VAS scores of group A were higher than those in groups B and C, Ramsay score of group A was lower than that of groups B and C at T2-T3, and Bromage score of group C at any time point was higher than other two groups. The time of the second stage of labor in groups B and C was longer than that in group A, which in group C was longer than that in group B. Compared with groups A and C, the blood pressure and heart rate of puerperae in group B were closer to normal values. Three different concentrations of ropivacaine had no significant effect on the umbilical artery blood gas analysis indices and Apgar scores at 1st minute and 5th minute in neonates. The incidence of maternal adverse reactions in group C was lower than those in groups A and B. CONCLUSION 0.1% ropivacaine combined with 0.5 μg/ml sufentanil through DPE technique has good analgesic efficacy and few adverse effects in obese puerperae.

Abstract
BACKGROUND Data on the efficacy and incidence of adverse effects associated with dexmedetomidine (DEX) as a local anesthetic adjuvant for patient-controlled epidural analgesia (PCEA) are inconclusive. This meta-analysis assessed the efficacy and risks of DEX for PCEA using opioids as a reference. METHODS Two researchers independently searched PubMed, Embase, Cochrane Library, and China Biology Medicine for randomized controlled trials comparing DEX and opioids as local anesthetic adjuvants in PCEA. RESULTS In total, 636 patients from seven studies were included in this meta-analysis. Postoperative patients who received DEX had lower visual analog scale (VAS) scores than those who received opioids at 4-8 h (mean difference [MD]: 0.61, 95% CI [0.45, 0.76], P < 0.001, I2 = 0%), 12 h (MD: 0.85, 95% CI [0.61, 1.09], P < 0.001, I2 = 0%), 24 h (MD: 0.59, 95% CI [0.06, 1.12], P = 0.030, I2 = 82%), and 48 h (MD: 0.54, 95% CI [0.05, 1.02], P = 0.030, I2 = 91%). Additionally, patients who received DEX had a lower incidence of itching (odds ratio [OR]: 2.86, 95% CI [1.18, 6.95], P = 0.020, I2 = 0%) and nausea and vomiting (OR: 6.83, 95% CI [3.63, 12.84], P < 0.001, I2 = 24%). In labor analgesia, no significant differences in neonatal (pH and PaO2 of cord blood, fetal heart rate) or maternal outcomes (duration of labor stage, mode of delivery) were found between the DEX and opioid groups. CONCLUSIONS Compared with opioids, using DEX as a local anesthetic adjuvant in PCEA improved postoperative analgesia and reduced the incidence of itching and nausea and vomiting without increasing the incidence of adverse events.

Abstract
OBJECTIVES To summarize and appraise the use of dexmedetomidine in epidural labor analgesia, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS We conducted the literature search about the RCTs of epidural labor analgesia with or without dexmedetomidine from inception until November 1, 2022, in the following databases: PubMed, Cochrane Library, and Embase. The primary outcome was visual analog scale (VAS) within 2 hours after epidural intubation. The secondary outcomes included the duration of the first and second labor stages, Apgar score, umbilical blood pH, dosage of analgesics, and side effects. RESULTS Eight RCTs including 846 parturients were included. The VAS score of the dexmedetomidine group was significantly lower than that of the control group at the time of 15 minutes (mean difference [MD] -1.41, 95% confidence interval [CI] -2.23, -0.59), 30 minutes (MD -1.02, 95% CI -1.70, -0.33), 60 minutes (MD -0.90, 95% CI -1.36, -0.44), and 90 minutes (MD -0.70, 95% CI -1.16, -0.23). The incidence of pruritus in the dexmedetomidine group was lower than that of the control group (MD 0.28, 95% CI 0.11, 0.74), but the incidence of maternal bradycardia was higher (MD 6.41, 95% CI 1.64, 25.04). There were no significant difference in other outcomes. DISCUSSION Dexmedetomidine combined with local anesthetic for epidural labor analgesia can improve the VAS score of parturients. Except for the increased incidence of maternal bradycardia, it seems to be safe for the parturients and fetuses.

Abstract
Background Dexmedetomidine, a potent and highly selective α2-adrenoreceptor agonist, has become a popular adjuvant to local anesthetics. This study was designed to investigate the effect of dexmedetomidine with ropivacaine for femoral nerve block on postoperative analgesia after total knee arthroplasty. Methods Forty-six patients after total knee arthroplasty received ultrasound-guided femoral nerve block with either 0.3% ropivacaine alone (group R) or 0.3% ropivacaine with 0.5 μg/kg dexmedetomidine (group RD). Total 24-h sufentanil consumption, visual analogue scale (VAS) pain scores, frequency of patient-controlled analgesia (PCA) pressed, Ramsay sedation score, the incidence of bradycardia and hypotension, and incidence of postoperative nausea and vomiting (PONV) were recorded. Results Compared to group R, the total 24-h sufentanil consumption was significantly reduced (110.76 ± 11.56 vs. 99.09 ± 13.31; P<0.05), the VAS scores were lower at 10 and 12 h postoperatively [3(2-3) vs. 2(1-2) and 3(2-3) vs. 2(1-3), respectively; P<0.05], the frequency of PCA pressed was lower at 8-12 and 12-16-h time intervals [(5(3-6) vs. 2(1-3) and 4(3-4) vs. 2(1-3), respectively; P<0.05]. However, there were no differences in Ramsay's sedation score and the incidence of PONV. Also, no patient experienced bradycardia and hypotension. Conclusions 0.5 μg/kg dexmedetomidine with 0.3% ropivacaine for femoral nerve block significantly decreased the total 24-h sufentanil consumption, prolonged and enhanced the analgesic efficacy of ropivacaine, without clinically relevant cardiovascular depression or over-sedation in patients undergoing total knee arthroplasty.

A randomized double-blinded study assessing the dose-response of ropivacaine with dexmedetomidine for maintenance of labor with epidural analgesia in nulliparous parturients. Front Pharmacol 2023; 14:1205301. [PMID: 37637415 PMCID: PMC10448189 DOI: 10.3389/fphar.2023.1205301] [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: 04/13/2023] [Accepted: 07/31/2023] [Indexed: 08/29/2023] Open
Abstract
Background: The combination of ropivacaine and dexmedetomidine has been used as an epidural analgesic for inducing labor. However, there is limited data regarding the administration of epidural analgesia for labor maintenance, hence, this study aimed to determine the optimum concentration through dose-response curves of ropivacaine plus dexmedetomidine, which could be used along with the Programmed Intermittent Epidural Bolus (PIEB) technique. Methods: One hundred parturients were randomized into 4 groups who were administered four different doses of ropivacaine (dexmedetomidine at 0.4 μg mL-1): 0.04%, 0.06%, 0.08%, and 0.1%. The primary outcome that was determined included the proportion of patients experiencing breakthrough pain during their 1st stage of labor. Breakthrough pain was described as a visual analog scale [VAS] score of >30 mm, requiring supplemental epidural analgesia after the administration of at least one patient-controlled bolus. The effective concentration of analgesia that was used for labor maintenance in 50% (EC50) and 90% (EC90) of patients were calculated with the help of probit regression. Secondary outcomes included epidural block characteristics, side effects, neonatal outcomes, and patient satisfaction. Results: The results indicated that the proportion of patients without breakthrough pain was 45% (10/22), 55% (12/22), 67% (16/24), and 87% (20/23) for 0.04%, 0.06%, 0.08%, and 0.10% doses of the analgesic that were administered, respectively. The EC50 value was 0.051% (95% confidence interval [CI], 0.011%-0.065%) while the EC90 value was recorded to be 0.117% (95% CI, 0.094%-0.212%). Side effects were similar among groups. Conclusion: A ropivacaine dose of 0.117% can be used as epidural analgesia for maintaining the 1st stage of labor when it was combined with dexmedetomidine (0.4 μg mL-1) and the PIEB technique.

Low-dose intranasal dexmedetomidine premedication improves epidural labor analgesia onset and reduces procedural pain on epidural puncture: a prospective randomized double-blind clinical study. BMC Anesthesiol 2023; 23:185. [PMID: 37254106 DOI: 10.1186/s12871-023-02146-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 05/18/2023] [Indexed: 06/01/2023] Open
Abstract
BACKGROUND Epidural labor analgesia is a safe and effective method of pain management during labor with the drawbacks of delayed onset and maternal distress during epidural puncture. This study aimed to determine whether pretreatment with intranasal low-dose dexmedetomidine effectively shortens the onset of analgesia and reduces procedural pain. METHODS In this prospective, randomized double-blind trial, nulliparous patients were randomly assigned to either the intranasal dexmedetomidine group or the control group. The intranasal dexmedetomidine group received 0.5 μg/kg dexmedetomidine intranasally, and the control group received an equal volume of normal saline intranasally. Both groups were maintained with a programmed intermittent epidural bolus. The primary outcome was the onset time of analgesia and scores of pain related to the epidural puncture. RESULTS Seventy-nine patients were enrolled, and 60 completed the study and were included in the analysis. The time to achieve adequate analgesia was significantly shorter in the intranasal dexmedetomidine group than in the control group (hazard ratio = 2.069; 95% CI, 2.187 to 3.606; P = 0.010). The visual analogue scale pain scores during epidural puncture in the intranasal dexmedetomidine group were also significantly lower than those in the control group (2.0 (1.8-2.5) vs. 3.5 (3.3-4.5), P ≤ 0.001, Table 2). Pretreatment with intranasal dexmedetomidine before epidural labor analgesia was associated with improved visual analogue scale pain scores and Ramsay scores, less consumption of analgesics and higher maternal satisfaction (P < 0.05). No differences were observed for labor and neonatal outcomes or the incidence of adverse effects between the two groups. CONCLUSIONS Pretreatment with intranasal dexmedetomidine before epidural labor analgesia yielded a faster onset of analgesia and decreased epidural puncture pain without increasing adverse effects. Pretreatment with intranasal dexmedetomidine may be a useful adjunct for the initiation of epidural analgesia, and further investigation should be encouraged to determine its utility more fully.

Evaluation of the Relationship between Baseline Autonomic Tone and Haemodynamic Effects of Dexmedetomidine. Pharmaceuticals (Basel) 2023; 16:ph16030354. [PMID: 36986456 PMCID: PMC10052810 DOI: 10.3390/ph16030354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 02/21/2023] [Accepted: 02/22/2023] [Indexed: 03/03/2023] Open
Abstract
Dexmedetomidine, a central α-2 agonist, is used for procedural sedation and for conscious sedation influences on heart rate and blood pressure. Authors verified whether it is possible to predict bradycardia and hypotension with the use of heart rate variability (HRV) analysis for an autonomic nervous system (ANS) activity assessment. The study included adult patients of both sexes with an ASA score of I or II scheduled for ophthalmic surgery to be performed under sedation. The loading dose of dexmedetomidine was followed by a 15 min infusion of the maintenance dose. The frequency domain heart rate variability parameters from the 5-min Holter electrocardiogram recordings before dexmedetomidine administration were used for the analysis. The statistical analysis also included pre-drug heart rate and blood pressure as well as patient age and sex. The data from 62 patients were analysed. There was no relationship between the decrease in heart rate (42% of cases) and initial HRV parameters, haemodynamic parameters or sex and age of patients. In multivariate analysis, the only risk factor for a decrease in mean arterial pressure (MAP) > 15% from the pre-drug value (39% of cases) was the systolic blood pressure before dexmedetomidine administration as well as for a >15% decrease in MAP sustained at more than one consecutive time point (27% of cases). The initial condition of the ANS did not correlate with the incidence of bradycardia or hypotension; HRV analysis was not helpful in predicting the abovementioned side effects of dexmedetomidine.

Abstract
Introduction: Dexmedetomidine is a potent, highly selective α-2 adrenoceptor agonist with sedative, analgesic, anxiolytic, and opioid-sparing properties. A large number of dexmedetomidine-related publications have sprung out in the last 2 decades. However, no bibliometric analysis for clinical research on dexmedetomidine has been published to analyze hot spots, trends, and frontiers in this field. Methods: The clinical articles and reviews related to dexmedetomidine, published from 2002 to 2021 in the Web of Science Core Collection, were retrieved on 19 May 2022, using relevant search terms. VOSviewer and CiteSpace were used to conduct this bibliometric study. Results: The results showed that a total of 2,299 publications were retrieved from 656 academic journals with 48,549 co-cited references by 2,335 institutions from 65 countries/regions. The United States had the most publications among all the countries (n = 870, 37.8%) and the Harvard University contributed the most among all institutions (n = 57, 2.48%). The most productive academic journal on dexmedetomidine was Pediatric Anesthesia and the first co-cited journal was Anesthesiology. Mika Scheinin is the most productive author and Pratik P Pandharipande is the most co-cited author. Co-cited reference analysis and keyword analysis illustrated hot spots in the dexmedetomidine field including pharmacokinetics and pharmacodynamics, intensive care unit sedation and outcome, pain management and nerve block, and premedication and use in children. The effect of dexmedetomidine sedation on the outcomes of critically ill patients, the analgesic effect of dexmedetomidine, and its organ protective property are the frontiers in future research. Conclusion: This bibliometric analysis provided us with concise information about the development trend and provided an important reference for researchers to guide future research.

[PMID: 37057296 PMCID: PMC10089781 DOI: 10.1155/2023/2358888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 01/30/2023] [Accepted: 03/03/2023] [Indexed: 04/15/2023] Open
Abstract
Objective To explore the efficacy and safety of different doses of dexmedetomidine (DEX) for epidural labor analgesia (ELA). Methods From June 2021 to June 2022, 147 parturients who underwent ELA in our hospital were selected and divided into low- (0.5 μg/kg DEX), medium- (0.75 μg/kg DEX), and high-dose (1.0 μg/kg DEX) groups (n = 49 for each) according to the random number table method. The analgesic effect was assessed using the Ramsay sedation score and Visual Analogue Scale (VAS), and the labor duration, mean arterial pressure (MAP), and heart rate (HR) before and after analgesia, vaginal bleeding within 2 h postpartum, and delivery outcomes (the cesarean section conversion rate and the neonatal Apgar score) were statistically analyzed. Furthermore, the incidence of adverse reactions was calculated, and maternal satisfaction with delivery was investigated. Results After analgesia, the the Ramsay and labor duration were higher in the high-dose group than those in the low- and medium-dose groups, and the VAS scores was lowerin the high-dose group than those in the low- and medium-dose groups(P < 0.05), while no difference was identified among the three groups in terms of the cesarean section conversion rate and the neonatal Apgar score (P > 0.05). The high-dose group had the greatest fluctuations in MAP and HR levels before and after analgesia than the other two groups, with a higher incidence of adverse reactions (P < 0.05). Finally, the survey of delivery satisfaction showed no significant difference in delivery satisfaction among the three groups (P > 0.05). Conclusion DEX has excellent performance in ELA, which can effectively relieve the pain of puerperae and shorten the labor process. Among them, low-dose DEX has higher safety and is recommended as the first choice. Trial Registrations. This trial is registered with ML2021073.

Abstract
INTRODUCTION Pain management for older patients with hip fractures is challenging. This study aimed to investigate the effect of ultrasound-guided fascia iliac compartment block (UGFICB) using different doses of nalbuphine in combination with ropivacaine on preoperative analgesia in older patients with hip fractures. METHODS In this multicenter randomized controlled trial, 280 elderly patients with hip fracture were randomly allocated into four UGFICB groups (n = 70 in each group): a ropivacaine group (30 mL 0.1% ropivacaine + 0.9% normal saline) and three ropivacaine plus nalbuphine groups (5, 10, and 20 mg nalbuphine, respectively). The primary outcomes were the duration of analgesia at rest and on passive movement. Secondary outcomes included sensory block area, side effects, and vital signs. The doses of rescue analgesia with parecoxib sodium were also analyzed. RESULTS The addition of nalbuphine dose-dependently increased the duration of analgesia at rest and on passive movement (P < 0.05) and expanded the area of sensory block (P < 0.05). Compared with the ropivacaine group, the pain scores at rest and on movement at 6 and 8 h after the block were lower in three ropivacaine plus nalbuphine groups (P < 0.05), without between-group differences at 2, 4, and 12 h. The four groups had comparable side effects (nausea and vomiting) and vital signs (P > 0.05). CONCLUSIONS UGFICB with 5, 10, and 20 mg nalbuphine added to ropivacaine prolonged the analgesia duration, increased sensory block area, reduced pain, and decreased the doses of rescue parecoxib sodium for older patients after hip fracture, without obvious side effects. Among these three doses, nalbuphine 20 mg in combination with ropivacaine provided the longest duration of analgesia and the largest sensory block area.

Analgesic Effects, Birth Process, and Prognosis of Pregnant Women in Normal Labor by Epidural Analgesia Using Sufentanil in Combination with Ropivacaine: A Retrospective Cohort Study. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:1228006. [PMID: 36072747 PMCID: PMC9444351 DOI: 10.1155/2022/1228006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/28/2022] [Accepted: 08/08/2022] [Indexed: 11/17/2022]
Abstract
Objective. The objective is to evaluate the analgesic, labor, and prognostic effects of patient-controlled epidural analgesia (PCEA) versus sufentanil in conjunction with ropivacaine in normal labor. Methods. Sixty pregnant women who had a normal delivery at our hospital between February 2019 and April 2021 were included. Pregnant women were arbitrarily assigned to a control group and a research group. Pregnant women in the control group received lidocaine analgesia and PCEA with sufentanil combined with ropivacaine in the research group. Satisfaction with care, fetal umbilical artery blood flow, VAS score, labor and bleeding, neonatal Apgar score and incidence of adverse events were analyzed. Results. First, we made a comparison of satisfactory performance of nursing care. The satisfaction rate of the research group was 100.00%, compared to 83.33% for the control group. Nursing satisfaction was higher in the research group, and the difference was statistically significant (
). Following analgesia, PI, RI, and S/D values of umbilical artery blood flow were lower in the research group than those in the control group, but the difference was not statistically significant (
). The VAS scores at 10 min, 20 min, and 30 min were found to be lower in the research group than in the control group after analgesia, and the difference was statistically significant (
). Bleeding was significantly lower in the research group for all stages of labor, and the difference was statistically significant (
). Apgar scores at 1 minute, 5 minutes, and 10 minutes postpartum were greater in the research group than in the control group, and the difference was statistically significant (
). As a final note, the incidence of pruritus, hypotension, respiratory depression, nausea, and vomiting was found to be lower in the research group than in the control group, and the difference was statistically significant (
). Conclusion. PCEA with sufentanil coupled with ropivacaine was used to perform labor analgesia. With significant reduction in maternal pain and assurance of labor, ropivacaine combined with sufentanil epidural labor analgesia did not reduce fetal umbilical artery blood flow without extended labor. It could not affect the labor process or the safety of the fetus, which is safe for the mother and fetus.

Abstract
In order to provide corresponding anesthesia methods of hepatobiliary diseases and obtain better clinical effect, the hemodynamics and clinical efficacy are evaluated by using different doses of dexamethasone (DEX) during the operation. 97 patients undergoing general anesthesia for hepatobiliary surgery in our hospital from April 2020 to August 2021 are analyzed retrospectively. All patients are divided into G1 (n = 24), G2 (n = 24), G3 (n = 24), and control group (n = 25) according to the random number table method. The G1, G2, and G3 groups are injected with DEX 1.0 ug/kg, DEX 0.8 ug/kg, and DEX 0.5 ug/kg by intravenous infusion pump before induction of general anesthesia, and the control group is injected with 0.9%Nacl solution 10 mL. Intraoperative anesthesia time, postoperative eye opening time, and extubation time of all groups are observed, and the incidences of postoperative adverse reactions are compared. The experimental results show that during general anesthesia in the liver and gallbladder surgery, the patients with high dose of DEX can better maintain the intraoperative hemodynamic parameters, and effectively restrain the postoperative stress reaction.

Abstract
INTRODUCTION Sufentanil is used with ropivacaine in labor pain management but it can have respiratory depression. Dexmedetomidine is effective to maintain hemodynamic stability in parturient women and allow awake intubation. However, dexmedetomidine is suggested only in patients with major cardiovascular disease that mandates stable hemodynamics (Reference ID: 3987541-USFDA). The objective of the study was to compare different doses of ropivacaine either with sufentanil or with dexmedetomidine for epidural anesthesia regarding labor pain management. METHODS Parturient women have received 0.125% ropivacaine with 0.5-μg/mL sufentanil (SR1 cohort, n = 115), or 0.08% ropivacaine with 0.5-μg/mL sufentanil (SR2 cohort, n = 109), or 0.125% ropivacaine with 0.5-μg/mL dexmedetomidine (DR1 cohort, n = 124), or 0.08% ropivacaine with 0.5-μg/mL dexmedetomidine (DR2 cohort, n = 135) for epidural anesthesia during vaginal delivery or cesarean section. RESULTS At 2-h postpartum, the visual analog scale score of parturient women of the DR2 cohort was fewer than that of parturient women of the SR1 (p < 0.0001, q = 4.162) and the SR2 (p < 0.0001, q = 7.568) cohorts and statistically the same as that of parturient women of the DR1 cohort (p < 0.0001, q = 3.087). Bradycardia and itching were reported in parturient women of the DR2 and the DR1 cohorts while nausea, vomiting, and urinary retention at 6 h were reported in parturient women of the SR1 and the SR2 cohorts. In the DR2 cohort, there were fewer numbers of parturient women with bradycardia (4 vs. 19, p < 0.0001, q = 6.613) and hypotension (2% vs. 1%) than those in the DR1 cohort. The child born by women of the DR2 cohort had high partial arterial pressure of oxygen than those born by women of the DR1 (p < 0.0001, q = 18.663), the SR1 (p < 0.0001, q = 29.366), and the SR2 (p < 0.0001, q = 24.039) cohorts. DISCUSSION/CONCLUSION Epidural 0.08% ropivacaine with 0.5-μg/mL dexmedetomidine is an effective and safe anesthetic regimen for hypertensive parturient women and their newborns. LEVEL OF EVIDENCE III. Technical Efficacy Stage: 4.

Analgesic Effects of Dexmedetomidine Combined with Spinal and Epidural Anesthesia Nursing on Prostate Hyperplasia Patients after Transurethral Resection of Prostate by Intelligent Algorithm-Based Magnetic Resonance Imaging. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:4243244. [PMID: 35637847 PMCID: PMC9148224 DOI: 10.1155/2022/4243244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/13/2022] [Accepted: 04/23/2022] [Indexed: 11/17/2022]
Abstract
To analyze the investigation of the application effects of different doses of dexmedetomidine (Dex) with combined spinal and epidural anesthesia nursing on analgesia after transurethral resection of prostate (TURP) by intelligent algorithm-based magnetic resonance imaging (MRI), MRI imaging segmentation model of mask regions with convolutional neural network (Mask R-CNN) features was proposed in the research. Besides, the segmentation effects of Mask R-CNN, U-net, and V-net algorithms were compared and analyzed. Meanwhile, a total of 184 patients receiving TURP were selected as the research objects, and they were divided into A, B, C, and D groups based on random number table method, each group including 46 cases. Patients in each group were offered different doses of Dex, and visual analogue scale (VAS) and Ramsay scores of different follow-up visit time, use of other analgesics, the incidence of postoperative cystospasm, and nursing satisfaction of patients in four groups were compared. The results demonstrated that Dice similarity coefficient (DSC) value, specificity, and positive predictive value of Mask R-CNN algorithm were
, 98.61%, and 69.57%, respectively, all of which were higher than those of U-net and V-net algorithms. Pain VAS scores and the incidence of cystospasm at different time periods of groups B and C were both significantly lower than those of group D (
). Ramsay scores of groups B and C at 8 hours, 12 hours, 24 hours, and 48 hours after the operation were all remarkably higher than those in group D (
). Besides, nursing satisfaction of groups B and C was obviously superior to that in group D, and the difference demonstrated statistical meaning (
). The differences revealed that Dex showed excellent analgesic and sedative effects and could effectively reduce the incidence of complications after TURP, including cystospasm and nausea. In addition, it helped improve nursing satisfaction and patient prognosis.

Abstract
Objective The present study is designed to study the analgesic and sedative effect of different doses of dexmedetomidine combined with butorphanol in continuous analgesia after a cesarean section. Methods A total of 60 puerperae undergoing a cesarean section recruited from a single center were divided into three groups according to the postoperative continuous analgesia protocol: control group (100 mL of normal saline containing 10 µg/kg fentanyl and 0.25 mg of palonosetron, 2 mL/h for continuous analgesia for 48 h), DB1 group (100 mL of normal saline containing 1.0 µg/kg dexmedetomidine, 4 mg of butorphanol, 10 µg/kg fentanyl, and 0.25 mg of palonosetron, 2 mL/h for continuous analgesia for 48 h), and DB2 group (100 mL normal saline containing 2.0 µg/kg dexmedetomidine, 4 mg of butorphanol, 10 µg/kg fentanyl, and 0.25 mg of palonosetron, 2 mL/h for continuous analgesia for 48 h). We compared the blood pressure, heart rate, oxygen saturation, VAS score, Ramsay score, and adverse reactions of puerperae among the three groups after surgery. Results The baseline data all have no significant difference in the three groups (p > 0.05). Compared with those in the control group, the systolic blood pressure, diastolic blood pressure, heart rate, and VAS score of the puerperae in the DB1 group and DB2 group were significantly decreased at 6, 24, and 48 h (P < 0.05), while the Ramsay scores of the puerperae in DB1 group and DB2 group were significantly increased at 6, 24, and 48 h (p < 0.05). At the same time, the systolic blood pressure, diastolic blood pressure, heart rate, and VAS score of the puerperae in the DB2 group were significantly lower than those in the DB1 group (P < 0.05), while the Ramsay scores of the puerperae in DB2 group were significantly higher than those in the DB1 group (P < 0.05). Also, there is no significant difference in oxygen saturation and adverse reactions of puerperae among the three groups after surgery (p > 0.05). Conclusion Dexmedetomidine combined with butorphanol can improve the analgesic and sedative effects in continuous analgesia after a cesarean section, and the analgesic and sedative effects of dexmedetomidine in the high-dose group are better than those in the low-dose group.

Abstract
Neuraxial labor analgesia is considered the gold standard technique for analgesia. Ideally, a good neuraxial technique uses dilute local anesthetic solutions to produce effective pain relief with no or minimal motor impairment. Adjuvant drugs that are co-administered with the local anesthetic either epidurally or intrathecally are useful in achieving this goal. The current review focuses on the effectivity and side-effect profile of various commonly used or tested adjuvants.

[PMID: 35284494 PMCID: PMC8913499 DOI: 10.3389/fsurg.2022.842776] [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: 12/24/2021] [Accepted: 01/24/2022] [Indexed: 11/21/2022] Open
Abstract
Background To explore the effect of dexmedetomidine (Dex)-assisted intravenous anesthesia on gastrointestinal motility in patients with colon cancer (CC) after open colectomy. Methods A total of 102 patients with CC, undergoing open colectomy in our hospital from January 2018 to January 2020, were selected and randomly divided into an observation group (n = 51) and a control group (n = 51). The patients in the control group received a routine combination of intravenous and inhalation anesthesia (CIIA), while those in the observation group received a Dex-assisted CIIA. The systolic blood pressure (SBP), the diastolic blood pressure (DBP), heart rate (HR), and the mean arterial pressure (MAP) were compared at different time points between the two groups. In addition, the intraoperative general conditions, the dosage of anesthetics, and the recovery of gastrointestinal functions were also compared between the two groups. Moreover, before operation and at 24 h after operation, the levels of serum gastrin (GAS) and plasma motilin (MTL) were detected by radioimmunoassay, and the level of plasma cholecystokinin (CCK) was detected by an enzyme-linked immunosorbent assay. The incidence of gastrointestinal complications was recorded in both groups. Results At T1-T3, the HR, SBP, DBP, and MAP levels were lower in both groups than those at T0. In addition, they were also lower in the observation group than those in the control group, showing significant differences (p < 0.05). The dosage of propofol and remifentanil in the observation group was lower than that in the control group, and there was a significant difference (p < 0.05). In the observation group, the postoperative first exhaust time, first defecation time, first ambulation time, and first feeding time were all earlier than those in the control group with significant differences (p < 0.05). After the operation, the observation group had higher levels of GAS and MTL but a lower level of CCK than the control group, and the differences were significant (p < 0.05). The incidence rate of gastrointestinal complications in the observation group (7.04%) was lower than that in the control group (19.61%), and there was a significant difference (χ2 = 4.346, p < 0.05). Conclusions Dex-assisted intravenous anesthesia can facilitate the recovery of gastrointestinal motility, can regulate the levels of gastrointestinal hormones, and can stabilize the levels of hemodynamic indexes in patients with CC after open colectomy.

Abstract
The study focused on the application value of ultrasound images processed by restoration algorithm in evaluating the effect of dexmedetomidine in preventing neurological disorder in patients undergoing sevoflurane anesthesia. 90 patients undergoing tonsillectomy anesthesia were randomly divided into normal saline group, propofol group, and dexmedetomidine group. The ultrasound images were processed by restoration algorithm, and during the postoperative recovery period, ultrasound images were used to evaluate. The results showed that the original ultrasonic image was fuzzy and contained interference noise, and that the image optimized by restoration algorithm was clear, without excess noise, and the image quality was significantly improved. In the dexmedetomidine group, the extubation time was 10.6 ± 2.3 minutes, the recovery time was 8.4 ± 2.2 minutes, the average pain score during the recovery period was 2.6 ± 0.7, and the average agitation score was 7.2 ± 2.4. Of 30 patients, there were 13 cases with vertigo and 1 case with nausea and vomiting. The vascular ultrasound imaging showed that, in the dexmedetomidine group, the peak systolic velocities (PSV) of the bilateral vertebral arteries during the recovery period were 67.7 ± 14.3 and 67.9 ± 15.2 cm/s, respectively; the end-diastolic velocities (EDV) of the bilateral vertebral arteries were 27.8 ± 6.7 and 24.69 ± 5.9 cm/s, respectively; the PSV in bilateral internal carotid artery systolic peak velocities were 67.2 ± 13.9 and 67.8 ± 12.7 cm/s, respectively; the EDV in bilateral internal carotid arteries were 27.7 ± 5.3 and 26.9 ± 4.9 cm/s, respectively; bilateral vertebral artery resistance indexes (RIs) were 0.6 ± 0.02 and 0.71 ± 0.08, respectively; the bilateral internal carotid artery RIs were 0.57 ± 0.04 and 0.58 ± 0.06, respectively, all better than the normal saline group (12.1 ± 2.5 minutes, 10.1 ± 2.3 minutes, 3.9 ± 0.6, 10.6 ± 3.7, 15 cases, 11 cases, 81.5 ± 13.6, 80.7 ± 11.6 cm/s, 29.3 ± 6.8, 28.9 ± 6.7 cm/s, 74.3 ± 10.2, 73.9 ± 12.5 cm/s, 29.1 ± 4.3, 29 ± 4.5 cm/s, 0.84 ± 0.06, 0.83 ± 0.05, 0.8 ± 0.04, and 0.81 ± 0.05) and the propofol group (11.4 ± 2.1 minutes, 9.0 ± 2.1 minutes, 3.4 ± 0.8, 8.5 ± 2.3, 12 cases, 9 cases, 72.5 ± 12.9, 73.4 ± 11.8 cm/s, 28.6 ± 5.4, 26.5 ± 5.1 cm/s, 72.1 ± 11.4, 73.5 ± 10.6 cm/s, 28.8 ± 5.6, 27.3 ± 4.7 cm/s, 0.78 ± 0.07, 0.82 ± 0.06, 0.76 ± 0.03, and 0.78 ± 0.05), and the differences were statistically significant (P < 0.05). In conclusion, ultrasound images processed by restoration algorithm have high image quality and high resolution. The dexmedetomidine can prevent neurological disorder in patients with sevoflurane anesthesia and is suggested in postoperative rehabilitation.

Abstract
ABSTRACT Percutaneous endoscopic lumbar discectomy causes less damage to the paravertebral musculature, with preservation of bone structure and rapid recovery. This innovation allows the surgery to be performed on an outpatient basis, due to the faster recovery time. The anesthesia traditionally performed was general anesthesia, and then conscious sedation. The prone position has always been a major challenge for anesthesiologists. In order to avoid any type of respiratory depression, and based on our own experience with obstetric analgesia, we propose to perform an analgesic spinal anesthesia, a technique not yet found for this type of surgery in the world literature.

Effect of Epidural Dexmedetomidine as an Adjuvant to Local Anesthetics for Labor Analgesia: A Meta-Analysis of Randomized Controlled Trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:4886970. [PMID: 34745286 PMCID: PMC8568549 DOI: 10.1155/2021/4886970] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Accepted: 10/16/2021] [Indexed: 12/15/2022]
Abstract
Background This study aims to determine the analgesic effect and safety of dexmedetomidine as an adjuvant to epidural local anesthetics during labor. Methods Randomized controlled trials comparing epidural blocks with or without dexmedetomidine for labor analgesia were comprehensively searched. Review manager 5.4 was used to analyze the extracted data. Results Compared with placebo and opioids, dexmedetomidine relieved labor pain of 15 min (P=0.002), 30 min (P=0.01), and 120 min (P=0.02) after block and at the moment of fetal disengagement (P=0.0002), decreased mean arterial pressure of 120 min (P=0.01), heart rate of 30 min (P=0.003), 60 min (P < 0.00001), and 120 min (P < 0.00001) after block, blood loss (P=0.02), and the incidence of nausea/vomiting (P=0.006), and increased the incidence of maternal bradycardia (P=0.04). However, sensitivity analysis only found that the incidence of nausea/vomiting was significantly different. Compared with placebo, dexmedetomidine relieved labor pain of 30 min after block (P < 0.00001) and did not increase the incidences of side effects, but only two studies were enrolled. Compared with opioids, dexmedetomidine decreased the incidence of nausea/vomiting (P=0.002), increased the incidence of maternal bradycardia (P=0.04), and had a similar effect on labor pain relief; however, sensitivity analysis found that significant difference existed only at the incidence of nausea/vomiting. Other outcomes from meta-analysis or subgroup analysis were not different. Conclusions Epidural dexmedetomidine has the potential to offer a better analgesic effect than placebo, similar labor pain control to opioids, and has no definite adverse effects on the parturient or fetus, but more high-quality studies are needed to confirm these conclusions.

Abstract
BACKGROUND Whether epidural administered sufentanil combined with low-concentration ropivacaine affected labor progress as well as maternal and neonatal outcomes still remained unknown. The aim of this study was to assess the impact of epidural sufentanil plus ropivacaine on maternal and neonatal outcomes. METHODS This is a retrospective cohort study. Data of singleton full-term pregnancy women who received epidural labor analgesia for vaginal delivery from May 2018 to June 2020 were collected. Parturients were divided into two groups (the R group and the SR group) according to different medication regimens for epidural labor analgesia. The implementation of epidural analgesia during labor was performed with 0.167 % ropivacaine in the R group and 0.1 % ropivacaine in combination with 0.5 µg/ml sufentanil in the SR group. The primary outcome of our study included the duration of labor progress and the incidence of maternal fever, postpartum hemorrhage, fetal distress and neonatal Apgar scores less than 7 at 1 and 5 min. The secondary outcome included the incidence of episiotomy, instrumental delivery, caesarean section and grade III meconium-stained amniotic fluid. RESULTS There were a total 3778 deliveries during the study period, 1994 and 1784 parturients were included in the R group and in the SR group, respectively. The length of the first stage of labor was remarkably shorter in the R group in comparison to the SR group (548.0 ± 273.0 vs. 570.9 ± 273.0, P = 0.013). No significant difference was found in the incidence of maternal fever, postpartum hemorrhage, fetal distress and in the neonatal Apgar scores less than 7 at 1 and 5 min between two groups. Other Maternal outcomes were comparable in the R group and the SR group. CONCLUSIONS 0.5 µg/ml sufentanil plus 0.1 % ropivacaine for epidural labor analgesia prolonged the duration of the first stage of labor, but did not have additional impact on maternal and neonatal outcomes compared with the sole 0.167 % ropivacaine.

Abstract
Purpose of Review This article provides an update of recent practice trends in neuraxial labor analgesia. It reviews available evidence regarding management of labor pain in obstetric patients with COVID-19, serious adverse events in obstetric anesthesia to help inform risk/benefit decisions, and increasingly popular neuraxial labor analgesia techniques and adjuvants. State-of-the-art modes of epidural drug delivery are also discussed. Recent Findings There has recently been a focus on several considerations specific to obstetric anesthesia, such as anesthetic management of obstetric patients with COVID-19, platelet thresholds for the safe performance of neuraxial analgesia in obstetric patients with thrombocytopenia, and drug delivery modes for initiation and maintenance of neuraxial labor analgesia. Summary Neuraxial labor analgesia (via standard epidural, dural puncture epidural, and combined spinal epidural techniques) is the most effective therapy to alleviate the pain of childbirth. SARS-CoV-2 infection is not, in and of itself, a contraindication to neuraxial labor analgesia or cesarean delivery anesthesia. Early initiation of neuraxial labor analgesia in patients with COVID-19 is recommended if not otherwise contraindicated, as it may reduce the need for general anesthesia should emergency cesarean delivery become necessary. Consensus regarding platelet thresholds for safe initiation of neuraxial procedures has historically been lacking. Recent studies have concluded that the risk of spinal epidural hematoma formation after neuraxial procedures is likely low at or above an imprecise range of platelet count of 70–75,000 × 106/L. Thrombocytopenia has been reported in obstetric patients with COVID-19, but severe thrombocytopenia precluding initiation of neuraxial anesthesia is extremely rare. High neuraxial blockade has emerged as one of the most common serious complications of neuraxial analgesia and anesthesia in obstetric patients. Growing awareness of factors that contribute to failed conversion of epidural labor analgesia to cesarean delivery anesthesia may help avoid the risks associated with performance of repeat neuraxial techniques and induction of general anesthesia after failed epidural blockade. Dural puncture techniques to alleviate the pain of childbirth continue to become more popular, as do adjuvant drugs to enhance or prolong neuraxial analgesia. Novel techniques for epidural drug delivery have become more widely disseminated.

Abstract
OBJECTIVE To investigate the application value of ropivacaine combined with sufentanil for epidural labor analgesia in painless labor. METHODS A total of 157 cases of pregnant female received painless labor in our hospital from January 2019 to December 2020 were randomly divided into observation group (n=81 cases) and control group (n=76 cases). The subjects in the observation group received 0.1% ropivacaine combined with sufentanil (0.25 μg/ml) 10 ml and added into the painless delivery pump, and the control group received 0.1% ropivacaine 10 ml into the painless delivery pump. The analgesic effect, lactation function, delivery outcomes and the labor course of the two groups were compared. RESULTS In the active stage of labor, the time of first labor process was shorter compared with the control group, those in the observation group were more active than the control group (P<0.05). The lactation initiation time of the observation group was shorter than that of the control group, and the effective rate of lactation was higher than that of the control group (P<0.05). The Visual analogue scale (VAS) score at 5 min, 30 min, 60 min, and 90 min after analgesia were improved in the observation group, the analgesic effect of ropivacaine combined with sufentanil for epidural labor analgesia was prior to ropivacaine alone. There were significant differences in the rates of conversion to cesarean section and usage rate of forceps between the two groups (P<0.05), while there had no significant differences in lateral episiotomy rate and Apgar scores at 1 and 5 min after birth between the two groups (P>0.05). CONCLUSION Ropivacaine combined with sufentanil for epidural labor analgesia in painless labor can effectively relieve labor pain, improve lactation function, active the first stage of labor, shorten the time of labor, reduce the incidence of cesarean section and ensure the safety of mother and infant.

Abstract
PURPOSE Epidural analgesia in the latent phase of the first stage of labor has been recognized and accepted by anesthesiologists worldwide. However, there is no unified consensus on the exact dosage of sufentanil with the combination of ropivacaine in the induction of epidural analgesia in the early first stage of labor. In this sequential dose-finding study, the 90% effective dose (ED90) of sufentanil for epidural administration in the early first stage of labor was estimated to minimize the adverse effects of using higher doses. METHODS Forty parturients with cervical dilatation of 2 to 4 cm who requested epidural analgesia were enrolled in this study. Parturients received 15 mL of a combination of ropivacaine 13 mg and the test dose of sufentanil. The initial dose of sufentanil in epidural administration was 1 μg, and the dose of sufentanil for the next parturient was based on the response of the preceding participant as per a biased coin up-and-down design. The primary outcome was the dose of sufentanil that resulted in successful epidural administration by maintaining the parturients' visual analog scale scores at ≤30 mm in the first 15, 30, and 45 minutes of induction. The ED90 and 95% CIs were estimated using isotonic regression methods and bootstrapping. FINDINGS The estimated ED90 of sufentanil in epidural administration in the early first stage of labor was 1.91 μg (95% CI, 1.82-2.35 μg) in this sequential dose-finding study. IMPLICATIONS Sufentanil at a dosage of 2 μg is recommended for the administration of epidural analgesia in parturients in the early first stage of labor. ChiCTR.org.cn identifier: 1900021683.

INTRODUCTION Intrapartum fever occurs frequently during labor. The purpose of this study was to investigate the effects of epidural dexmedetomidine on maternal temperature, pain score and adverse effects during labor analgesia. METHODS A total of 600 full-term primiparous parturients were randomly divided into two groups. The dexmedetomidine group (Group Dex, n = 300) received 0.1% ropivacaine with 0.5 µg/mL dexmedetomidine for epidural analgesia during labor, while the control group (Group C, n = 300) received 0.1% ropivacaine alone. The maternal temperature, visual analogue scale (VAS) and Ramsay sedation score (RSS) were recorded, and the systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were monitored. Side effects, if any, were also recorded. RESULTS The incidence of intrapartum fever was lower in Group Dex than in Group C (4.1% vs. 8.7%, χ2 = 5.07, P = 0.024). VAS values from the time of 3 cm cervical dilatation to 10 cm cervical dilatation were also lower in Group Dex than in Group C (1.0 ± 0.9 vs. 1.3 ± 0.7, t = 3.62, P < 0.001; 2.8 ± 0.8 vs. 3.3 ± 0.8, t = 8.09, P < 0.001; 3.1 ± 0.9 vs. 3.3 ± 0.8, t = 3.88, P < 0.001; 3.6 ± 0.8 vs. 4.1 ± 1.0, t = 5.86, P < 0.001, respectively). HR from the time of 3 cm cervical dilatation to 10 cm cervical dilatation was lower during labor in Group Dex than in Group C (80.0 ± 4.3 vs. 83.1 ± 5.4 beats/min, t = 7.58, P < 0.001; 81.1 ± 4.0 vs. 83.7 ± 5.5 beats/min, t = 6.48, P < 0.001; 78.9 ± 5.4 vs. 81.5 ± 6.3 beats/min, t = 5.41, P < 0.001; 83.1 ± 5.3 vs. 84.8 ± 5.6 beats/min, t = 3.75, P < 0.001, respectively), while SBP and DBP were similar between the two groups. The incidence of adverse events during labor was also similar between the two groups. CONCLUSION The present study showed that dexmedetomidine could reduce the incidence of intrapartum fever and relieve pain during labor without increasing adverse events.

Abstract
Objective The optimal concentration of ropivacaine as epidural labor analgesia combined with sufentanil has not been established. This study aimed to determine the median effective concentration (EC50) of epidural ropivacaine for labor analgesia in healthy term pregnancy when co-administered with sufentanil as an adjuvant or alone. Patients and Methods Sixty healthy parturients scheduled for epidural labor analgesia were enrolled in the study. They were divided into a saline group (Group C) and an epidural sufentanil (0.5 µg/mL) group (Group S). The initial concentration of ropivacaine was set at 0.125%, which was then varied by 0.01% using the up-and-down sequential allocation method. The hemodynamics were continuously monitored during delivery. A visual analog scale was used to evaluate the degree of pain. The Ramsay sedation score, duration of the labor stages, the onset of epidural analgesia, and adverse effects were recorded. Neonatal outcomes were evaluated using the Apgar scores and umbilical artery blood gas analysis. Results The EC50 of ropivacaine was 0.085% (95% CI, 0.079–0.090%) in Group S and 0.109% (95% CI, 0.105–0.112%) in Group C. The EC95 of ropivacaine was 0.096% (95% CI, 0.090–0.118%) in Group S, and 0.116% (95% CI, 0.113–0.127%) in Group C. The difference between the groups was statistically significant (p < 0.001). The stable hemodynamics, satisfactory analgesia, and good neonatal outcomes were comparable in both groups (P > 0.05). Conclusion The EC50 of ropivacaine was reduced by 22% when co-administered with sufentanil for epidural labor analgesia in primipara. (www.chictr.org.cn; registration number: ChiCTR2000039547).

Abstract
OBJECTIVE α2‑agonists and opioids have been used as intrathecal adjuvants to local anesthetics for several years, but the effect of intrathecal dexmedetomidine (Dex) or sufentanil combined with epidural ropivacaine in labor analgesia is not fully understood. METHODS A total of 108 parturient women receiving combined spinal-epidural labor analgesia were randomly divided into three groups. Group C received l mL saline (0.9%) intrathecally, Group D received 5 µg Dex intrathecally, and Group S received 5 µg sufentanil intrathecally. All parturient women then received 0.1% epidural ropivacaine and 0.2 µg/mL sufentanil for patient-controlled epidural analgesia with standard settings. The visual analog scale score, onset time, duration of intrathecal injection, local anesthetic requirements, and side effects were recorded. RESULTS The labor analgesia effects in Groups D and S were better than those in Group C. Groups D and S displayed significantly shorter onset times, longer durations of intrathecal injection, and reduced local anesthetic requirements compared with Group C. The incidence of shivering and pruritus in Group D was lower than that in Group S. CONCLUSION Intrathecal administration of 5 µg Dex could improve epidural labor analgesia effects.This randomized controlled clinical trial was registered with the Chinese Clinical Registry Center (ChiCTR-1800014943, http://www.chictr.org.cn/).

Abstract
Background Recently, one of the problems in developing countries is pregnant women who insist on cesarean section for fear of painful vaginal delivery. There are various methods to reduce labor pain, including medical and non-medical methods. Neuraxial analgesia is classified as one of the best ways to reduce labor pain. Epidural analgesia is a classic and popular procedure to decrease labor pain. Nevertheless, other methods, such as spinal or combined spinal-epidural analgesia, is more effective compared with the epidural. Objectives In this study, we investigated a single intrathecal versus epidural injection in pregnant women during childbirth. Methods In our research, after obtaining informed consent, the patients were randomly assigned to two equal groups: epidural and spinal. Each group contained 50 parturient women in advanced labor. In the epidural group, 2.5 mL isobaric bupivacaine 0.5%, sufentanil (0.2 mcg/mL), and 7 mL saline 0.9% were injected by an 18-gauge Tuohy needle at the L4-5 or L5-S1 intervertebral space, and in the spinal group, 0.5 mL isobaric bupivacaine 0.5%, 2.5 mcg sufentanil, and 0.5 mL saline 0.9% were injected by a 25-gauge pencil-point Quincke needle at the L4-5 or L5-S1 intervertebral spaces. For pain intensity, the visual analog scale (VAS) was used at serial intervals, and other variables, such as the onset and duration of analgesia, hypotension, neonatal APGAR score, fetal heart rate (FHR) changes, and other variables were examined. Results The mean time to onset analgesic effect was 4.6 min in the spinal group compared with 12.5 minutes in the epidural (P < 0.001). Duration of analgesia was 121 minutes in the spinal group compared with 104 min in the epidural group (P < 0.001). The time to reach the maximum block was 8.4 min in the spinal group vs. 22.2 min in the epidural group (P < 0.001). The duration of the second and third gestation stages was the same in both groups. Conclusions Spinal analgesia is short and easy to perform and does not require advanced equipment and technical experience. Spinal analgesia can be a good option for labor analgesia and leads to achieving a lower pain score than epidural analgesia.

Abstract
STUDY OBJECTIVE Adjuvant dexmedetomidine can be used to reduce the required concentration of ropivacaine for labor epidural analgesia. However, the potency of dexmedetomidine has not been fully studied. The purpose of this study was to determine the median effective concentration (EC50) of ropivacaine with adjuvant dexmedetomidine. DESIGN Prospective, double-blind, up-down sequential allocation study. SETTING Academic medical center specializing in the care of women and children. PATIENTS One hundred and fifty healthy, term parturients requesting labor epidural analgesia were randomly assigned to 1 of 5 different concentrations of dexmedetomidine: 0 μg/ml, 0.3 μg/ml, 0.4 μg/ml, 0.5 μg/ml, or 0.6 μg/ml. INTERVENTIONS The study solution for the first patient in each group included the randomly assigned concentration of dexmedetomidine in 0.1% ropivacaine. Subsequent patients in each randomization group received the assigned concentration of dexmedetomidine in a new concentration of ropivacaine as determined by the up-down allocation methodology. Effective analgesia was defined as pain on the visual analogue scale of<3 at30 min after administration of local anesthetic. The up-down sequential allocation method and probit regression were used to calculate the EC50 of epidural ropivacaine. MEASUREMENTS The primary outcome was pain 30 min after administration of local anesthetic via epidural catheter. Exploratory outcomes included side effects, neonatal outcomes, and obstetric outcomes. MAIN RESULTS The EC50 values for ropivacaine in dexmedetomidine 0.4 μg/ml, 0.5 μg/ml, and 0.6 μg/ml (0.044% [95% CI 0.036% to 0.045%], 0.035% [95% CI 0.031% to 0.041%], and 0.039% [95% CI 0.034% to 0.045%], respectively) were lower compared to ropivacaine in dexmedetomidine 0 μg/ml and 0.3 μg/ml (0.086% [95% CI 0.081% to 0.092%], and, 0.069% [95% CI 0.056% to 0.076%], respectively). Differences between EC50 values for ropivacaine in dexmedetomidine 0.4 μg/ml, 0.5 μg/ml, and 0.6 μg/ml were not statistically significant. Results of our exploratory analyses did not reveal differences in side effects, neonatal outcomes, or obstetric outcomes. CONCLUSIONS In this study, the lowest concentration of dexmedetomidine in ropivacaine with the greatest clinical effect was 0.4 μg/ml, which is important because there may be no additional analgesic benefit of dexmedetomidine greater than 0.4 μg/ml.

Abstract
Background Although video-assisted thoracic surgery (VATS) can significantly reduce postoperative pain, the incidence is as high as 30–50%. The purpose of this study was to explore the safety and efficacy of ultrasound-guided serratus anterior plane block (SAPB) combined with dexmedetomidine (Dex) for patients undergoing VATS. Methods Eighty patients were randomized into two groups (20 mL 0.5% ropivacaine plus 0.5 µg/kg or 1 µg/kg Dex). Primary outcome was the visual analog scale of pain while coughing (VASc) score at 24 h after surgery. Secondary outcomes included hemodynamics, sufentanil consumption, number of patients needing rescue analgesia, time to first rescue analgesic, total dose of rescue analgesic, satisfaction scores of patients and surgeons, time of chest tube removal, length of hospital stay, adverse effects, the prevalence of chronic pain and quality of life. Results Compared with D1 group, visual analog scale of pain at rest (VASr) was significantly lower during the first 24 h after surgery, while VASc was significantly lower during the first 48 h after surgery (P<0.05). Mean arterial pressure was significantly decreased from T2 to T8, and heart rate was significantly decreased from T2 to T7 in the D2 group (P<0.05). Consumption of sevoflurane, remifentanil, DEX and the recovery time were significantly reduced in the D2 group (P <0.05). Consumption of sufentanil 8–72 h after surgery was significantly lower in the D2 group (P<0.05). Additionally, the number of patients who required rescue analgesia, the time to the first dose of rescue analgesia, and the total dose of rescue analgesia was significantly lower in the D2 group (P<0.05). Conclusion The results of this study show that 1 µg/kg DEX is a beneficial adjuvant to ropivacaine for single-injection SAPB in VATS patients while stable hemodynamics were maintained.

Abstract
Opioids and α2-agonists have been used as epidural adjuvants in local anesthetics for a long time, but the effect of the combination of opioids and α2-agonists as epidural adjuvants is not completely understood. In the present study, the combination of dexmedetomidine (Dex) and sufentanil as adjuvants to ropivacaine for epidural labor analgesia was investigated. A total of 108 parturient women receiving labor epidural analgesia were randomly divided into three groups: i) Group RD received 0.1% ropivacaine + 0.5 µg/ml Dex; ii) Group RS received 0.1% ropivacaine + 0.5 µg/ml sufentanil; and iv) Group RDS received 0.1% ropivacaine + 0.25 µg/ml Dex + 0.25 µg/ml sufentanil. Patients received a 10 ml loading dose followed by a maintenance by patient controlled epidural analgesia. The visual analog scale scores, onset time, local anesthetic requirements, motor blockage and adverse effects were recorded. Group RDS displayed an improved labor analgesia effect compared with Groups RD and RS. Group RDS displayed a shorter onset time compared with Groups RD and RS, and a reduced local anesthetic requirement compared with Group RS. The motor blockage in Groups RDS and RS was significantly lower compared with Group RD, and the incidence of pruritus in Groups RDS and RD was lower compared with Group RS. In conclusion, the combined use of 0.25 µg/ml Dex and 0.25 µg/ml sufentanil as adjuvants to 0.1% ropivacaine for epidural labor analgesia displayed an improved analgesia effect compared with the use of either 0.5 µg/ml sufentanil or 0.5 µg/ml Dex alone. The present study was registered with the Chinese Clinical Trial Registry Center on 23 February, 2018 (registration no. ChiCTR-IOR-1800014943).

Investigation of the Minimum Local Analgesic Concentration of Epidural Sufentanil Combined With Ropivacaine for Labor Analgesia. Clin Ther 2020; 42:210-219. [PMID: 31955968 DOI: 10.1016/j.clinthera.2019.10.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 10/17/2019] [Accepted: 10/21/2019] [Indexed: 12/18/2022]
Abstract
PURPOSE Worldwide, there are only few studies focusing on labor analgesia on the MLAC (minimum local analgesic concentration) or EC50 (median effective concentration) of sufentanil and ropivacaine. Therefore, we determine the MLAC or EC50 of sufentanil and ropivacaine for epidural analgesia by using an up-down sequential allocation and survey its adverse effect in a prospective blinded randomized trial. METHODS Sixty nulliparous full-term parturients who required labor analgesia were recruited and randomly divided into the sufentanil and ropivacaine groups. The formulation was 25 μg sufentanil combined with 0.1% ropivacaine (added 0.9% normal saline to 75 ml). According to the response of a previous parturient, the dosage of sufentanil was increased or decreased by 5 μg in the sufetanil group; meanwhile, we also administrated an initial concentration of 0.1% ropivacaine combined with 22.5 μg sufentanil (added 0.9% normal saline to 75 ml) in the ropivacaine group. The concentration of ropivacaine was increased or decreased by 0.01% following the response of the previous parturient. The Brownlee up-down sequential allocation was used to estimate the MLAC of epidural ropivacaine and its 95% confidence intervals in labor analgesia. FINDINGS There were no significant changes for the two groups, including for age, height weight, active stage, second stage of labor, and gestational weeks (P = 0.769, 0.900, 0.603, 0.441, 0.577, and 0.695, respectively). The VAS scores of the parturient decreased to varying degrees (P < 0.0001) after labor analgesia compared with VAS before labor analgesia, and the most effective analgesia was reached in 60 min. The EC50 dose of epidural ropivacaine combined with 0.3 μg/mL sufentanil was 0.09687%, and the 95% CI was 0.08944%~0.1043%. Five parturients had PONV, and the incidence rate was 16.7%; one parturient had pruritus, so the incidence rate was 3.3%. The EC50 dose of epidural sulfetanil combined with 0.1% ropivacaine was 18.76 μg with a 95% confidence interval of 13.5-24.48 μg. There were no significant differences in the active stage, second stage of labor, and maternal and fetal hemodynamic data between the two groups. Notably, the Apgar scores for 1 min and 5 min were 10 scores for almost all of these patients. There were no significant differences between the two groups for maternal and fetal side effects, which had very low incidence rates. IMPLICATIONS The MLAC of epidural sufentanil or ropivacaine could provide satisfactory and safe analgesia for parturients while having a low incidence rate of side effects.
