Abstract
OBJECTIVES The French AmbUlatory Extraperitoneal Cesarean Section (FAUCS) is aimed at improving patients' birth experience and recovery. However, data are scarce regarding its maternal and neonatal safety. This study seeks to compare maternal and neonatal outcomes between FAUCS and conventional cesarean deliveries at term. METHODS This was a retrospective cohort study involving women who underwent scheduled cesarean deliveries at term. We compared a total of 810 cases using the FAUCS technique with 217 cases using conventional cesarean deliveries. Surgical complications, adverse neonatal events, and maternal recovery parameters were compared. RESULTS The incidence of overall surgical complications was comparable between the 2 groups, with rates of 1.97% for FAUCS and 1.85% for the conventional cesarean deliveries. The rates of specific complications such as bladder injury (0.1%), bowel injury (0.1%), blood transfusion (1.35%), and postpartum hemorrhage (1%) were consistent with existing literature. Neonatal outcomes, including neonatal acidemia and admission rates to the neonatal intensive care unit, were comparable between the groups and demonstrated favourable comparisons with previously reported data. Notably, women in the FAUCS group required less analgesia, with only 0.8% receiving morphine, as opposed to 38% in the control group. Furthermore, the FAUCS group demonstrated significantly quicker recovery, with 86% achieving autonomy and early discharge at their discretion within 48 hours after operation, in contrast to only 17% in the control group. CONCLUSIONS When performed by experienced practitioners, FAUCS proves to be a safe procedure, with no increased risk for maternal or neonatal complications. Its significant benefits in terms of enhancing maternal recovery are noteworthy.

Abstract
OBJECTIVE This work aimed to study the effect of sustained hypotension after spinal on neonatal acidosis and adverse outcomes in those undergoing scheduled cesarean delivery (CD) with universal prophylactic vasopressor exposure and to examine differences in spinal-to-delivery time by neonatal acidosis status. STUDY DESIGN This retrospective cohort study conducted at a quaternary care center from January 2019 to December 2021 included singleton, term, nonanomalous pregnancies, with scheduled CD under spinal anesthesia. Hypotension was defined as a systolic blood pressure (SYS-BP) < 100 mm Hg (SYS-BP100) or a >20% drop from baseline blood pressure (SYS-BP20). Both the occurrence of hypotension and its magnitude and duration were studied; the latter through the development of a hypotension index. The 90th and 95th percentiles of the hypotension index for SYS-BP20 and SYS-BP100, respectively, were used to define sustained hypotension. The primary outcome was neonatal acidosis (umbilical artery pH ≤ 7.1 or base excess ≤ -12 mmol). Secondary outcomes were composites of neonatal (CNAO) and maternal (CMAO) adverse outcomes. Multivariable Poisson regression models with robust error variance analysis was used to estimate adjusted relative risks (aRRs) and 95% confidence intervals (CIs). RESULTS Our study included 332 individuals who underwent scheduled CD; among them 330 (99.4%) received prophylactic vasopressors. The rate of neonatal acidosis was 4.2%. Sustained hypotension after spinal anesthesia, which occurred in 12.3% of the cohort, was associated with increased risk for neonatal acidosis (aRR 3.96, 95% CI 1.21-12.98), but was not associated with CNAO or CMAO. Time from spinal-to-delivery was not different in those with and without neonatal acidosis. CONCLUSION Despite universal exposure to prophylactic vasopressors, sustained hypotension after spinal anesthesia was still associated with neonatal acidosis, but no other adverse perinatal outcomes. Our findings may provide additional support for the adoption of prophylactic vasopressors to reduce spinal hypotension and downstream effects on the neonate from intraoperative hemodynamic instability. KEY POINTS · Despite prophylactic vasopressors during scheduled CD, neonatal acidosis occurred in 4% of subjects.. · Sustained hypotension after spinal anesthesia was associated with neonatal acidosis, but not adverse neonatal outcomes.. · Spinal-to-delivery time was not associated with neonatal acidosis in scheduled CD..

Abstract
Background High altitudes are characterized by low-pressure oxygen deprivation. This is further exacerbated with increasing altitude. High altitudes can be associated with reduced oxygenation, which in turn, can affect labor, as well as maternal and fetal outcomes. Epidural anesthesia can significantly relieve labor pain. This study aimed to assess the effects of elevation gradient changes at high altitude on the analgesic effect of epidural anesthesia, labor duration, and neonatal outcomes. Methods We divided 211 women who received epidural anesthesia into groups according to varying elevation of their residence (76 in Xining City, mean altitude 2,200 m; 63 in Haibei Prefecture, mean altitude 3,655 m; and 72 in Yushu Prefecture, mean altitude 4,493 m). The analgesic effect was assessed using a visual analog scale (VAS). Labor duration was objectively recorded. The neonatal outcome was assessed using Apgar scores and fetal umbilical artery blood pH. Results VAS scores among the three groups did not differ significantly (p > 0.05). The neonatal Apgar scores in descending order were: Xining group > Haibei group > Yushu group (p < 0.05). The stage of labor was similar among the three groups (p > 0.05). Fetal umbilical artery blood pH in descending order were: Xining group > Haibei group > Yushu group (p < 0.05). Conclusion Elevation gradient changes in highland areas did not affect the efficacy of epidural anesthesia or labor duration. However, neonatal outcomes were affected.

Abstract
BACKGROUND Epidural analgesia may cause maternal hypotension and changes in the fetal heart rate. The implications of such side effects on the course of labor and delivery are incompletely understood. OBJECTIVE This study aimed to assess whether the occurrence of maternal or fetal side effects associated with labor epidural analgesia increased the risk for cesarean delivery. STUDY DESIGN This was a cohort study of all women who underwent epidural analgesia during labor for the period October 1, 2020 to December 31, 2020. Excluded were cases of multiples, fetal death, noncephalic presentation, and gestational age at birth <37.0 weeks. Maternal vital signs and fetal heart rate tracings for the 1 hour before and 1 hour after epidural analgesia was administered were reviewed. The occurrence of maternal hypotension, defined as a continuous variable and dichotomized into a decrease in maternal systolic blood pressure to <90 mm Hg or a drop in systolic blood pressure by >20% below the last value before epidural analgesia was administered, was related to changes in the fetal heart rate category. The principal outcome was cesarean delivery rate; binary logistic regression analysis was used to control for confounders, and mediation model analysis was used to quantify the extent to which significant variables participated in the causation pathway to cesarean delivery (SPSS version 28 was used for the analyses). RESULTS A total of 439 women met the study criteria. Significant adverse reactions owing to epidural occurred in 184 of 439 women (41.9%) and included severe maternal hypotension in 159 of 439 participants (36.2%) and worsening fetal heart rate category in 50 of 439 participants (11.4%). The logistic regression analysis revealed that cervical dilation at epidural (P=.03), the duration of labor after epidural (P<.001), and worsening fetal heart rate category within 60 minutes of epidural administration (P=.01) were independently associated with recourse to cesarean delivery. The mediation analysis showed that both cervical dilatation at epidural administration and worsening fetal heart rate category had significant direct and indirect effects in the pathway to cesarean delivery. CONCLUSION Worsening fetal heart rate category related to labor epidural independently increased the risk for cesarean delivery.

Abstract
BACKGROUND In scheduled cesarean deliveries, the rate of decrease in the umbilical artery pH is related to the severity of maternal hypotension and the interval from spinal placement to delivery. Base excess values have greater use than umbilical artery pH values to time the duration of fetal acidemia because they demonstrate a linear rather than logarithmic correlation with the degree of acidosis. OBJECTIVE This study aimed to evaluate the rate of decline in the fetal base excess in scheduled cesarean deliveries that were converted to emergency cesarean delivery owing to fetal bradycardia following spinal anesthesia. STUDY DESIGN All cases of scheduled cesarean deliveries in gestations at >34 weeks' gestation under spinal anesthesia that were converted to emergency cesarean deliveries owing to fetal bradycardia in the period May 2019 to May 2021 were reviewed. Included were those with (1) a preoperative reactive nonstress test and (2) fetal acidemia (umbilical artery pH <7.20). Excluded were those with anesthesia other than spinal and a birthweight below the 10th percentile for gestational age. Time intervals between the completion of spinal anesthesia and delivery were calculated and related to umbilical cord gas analytes. RESULTS From a cohort of 1064 scheduled cesarean deliveries, 7 fulfilled the study criteria yielding 8 neonates. Mean ± standard error of the mean interval of spinal anesthesia to delivery was 15.0±1.9 minutes, and the decrease in mean blood pressure after spinal anesthesia was 39.1±3.0 mm Hg. Umbilical artery base excess ranged from -5.2 to -16.6 mmol/L (median, -8.0). Based on published normative data of prelabor fetal umbilical artery base excess (-2±0.6 mmol/L), the mean rate of base excess decrease was 0.38±0.25 mmol/minute. CONCLUSION The rate of decrease in base excess when scheduled cesarean deliveries are converted to emergency cesarean deliveries owing to fetal bradycardia related to spinal anesthesia (1 mmol/2.6 min) matches the estimated rate of loss of base excess (1 mmol/2-3 minutes) reported in cases of severe bradycardia or sentinel events during labor.

A comparison of criteria for defining metabolic acidemia in live-born neonates and its effect on predicting serious adverse neonatal outcomes. Am J Obstet Gynecol 2023; 229:439.e1-439.e11. [PMID: 36972891 DOI: 10.1016/j.ajog.2023.03.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 03/18/2023] [Accepted: 03/21/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND Metabolic acidemia is a known risk factor for serious adverse neonatal outcomes in both preterm and term infants. OBJECTIVE This study aimed to evaluate the clinical significance of delivery umbilical cord gas measurements with regard to serious adverse neonatal outcomes, and to determine if distinct thresholds for defining metabolic acidemia differ in their ability to predict such adverse neonatal complications. STUDY DESIGN This is a retrospective cohort study of singleton live-born deliveries between January 2011 and December 2019. Stratification according to gestational age at birth (≥35 and <35 weeks of gestation) was performed, and comparisons of maternal characteristics, obstetrical complications, intrapartum events, and adverse neonatal outcomes were made between neonates with metabolic acidemia and those without. Metabolic acidemia (based on delivery umbilical cord gas analyses) was defined using both American College of Obstetricians and Gynecologists and Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria. The primary outcome of interest was hypoxic-ischemic encephalopathy requiring whole-body hypothermia. RESULTS A total of 91,694 neonates born at ≥35 weeks of gestation met the inclusion criteria. By American College of Obstetricians and Gynecologists criteria, 2659 (2.9%) infants had metabolic acidemia. Neonates with metabolic acidemia were at markedly increased risk for neonatal intensive care unit admission, seizures, need for respiratory support, sepsis, and neonatal death. Metabolic acidemia by American College of Obstetricians and Gynecologists criteria was associated with an almost 100-fold increased risk of hypoxic-ischemic encephalopathy requiring whole-body hypothermia (relative risk, 92.69; 95% confidence interval, 64.42-133.35) in neonates born at ≥35 weeks of gestation. Diabetes mellitus, hypertensive disorders of pregnancy, postterm deliveries, prolonged second stages, chorioamnionitis, operative vaginal deliveries, placental abruption and cesarean deliveries were associated with metabolic acidemia in neonates born ≥ 35 weeks of gestation. The highest relative risk was in those diagnosed with placental abruption (relative risk, 9.07; 95% confidence interval, 7.25-11.36). The neonatal cohort born <35 weeks of gestation had similar findings. When comparing those infants born ≥ 35 weeks of gestation with metabolic acidemia by American College of Obstetricians and Gynecologists criteria vs Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria, the Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria identified more neonates at risk for serious adverse neonatal outcomes. In particular, 4.9% more neonates were diagnosed with metabolic acidemia, and 16 more term neonates were identified as requiring whole-body hypothermia. Mean 1-minute and 5-minute Apgar scores were similar and reassuring among neonates born at ≥35 weeks of gestation with and without metabolic acidemia as defined by both American College of Obstetricians and Gynecologists and Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria (8 vs 8 and 9 vs 9, respectively; P<.001). Sensitivity and specificity were 86.7% and 92.2%, respectively, with the Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria, and 74.2% and 97.2% with the American College of Obstetricians and Gynecologists criteria. CONCLUSION Infants with metabolic acidemia identified on cord gas collection at delivery are at considerably greater risk of serious adverse neonatal outcomes, including an almost 100-fold increased risk of hypoxic-ischemic encephalopathy requiring whole-body hypothermia. Use of the more sensitive Eunice Kennedy Shriver National Institute of Child Health and Human Development criteria for defining metabolic acidemia identifies more neonates born at ≥35 weeks of gestation at risk for adverse neonatal outcomes, including hypoxic-ischemic encephalopathy requiring whole-body hypothermia.

Exploring factors influencing skin incision to the delivery time and their impact on neonatal outcomes among emergency cesarean deliveries indicated for non-reassured fetal heart rate status. Front Pediatr 2023; 11:1224508. [PMID: 37808561 PMCID: PMC10551621 DOI: 10.3389/fped.2023.1224508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 08/21/2023] [Indexed: 10/10/2023] Open
Abstract
Background The time interval between skin incision and delivery (S-D) is crucial in determining neonatal outcome; however, little is known about the influencing factors and their impact on neonatal outcomes, particularly among emergency cesarean deliveries (ECD) indicated for fetal distress. This study investigated the factors influencing S-D time and their effects on neonatal outcomes among mothers who underwent ECD for non-reassured fetal heart rate status. Methods This retrospective cohort study involved 426 mother-infant pairs over four years. We retrieved data from the medical records, including baseline characteristics, perioperative data, and neonatal outcomes. Using multivariable logistic regression analysis, adjusted odd ratios, and a 95% confidence interval, potential factors influencing S-D time and their impacts on neonatal outcomes were assessed. A p-value of less than 0.05 was considered statistically significant. Results Factors independently associated with longer S-D time (>8 min) were mothers who had previous CD (AOR 5.9: 95% CI 2.2-16.1), obese mothers (AOR 6.2: 95% CI 1.6-24.5), and the second stage of labor (AOR 5.3: 95% CI 2.4-11.7). Adverse neonatal outcomes, including a 5th minute Apgar score of less than 7, the need for NICU admission, and neonatal death, were significantly higher in the longer S-D time interval [47.7% vs. 8.9%; p-value 0.001], [21.9% vs. 9.1%; p-value 0.001], and [32% vs. 11.8%; p-value = 0.004], respectively. Obese mothers and the second stage of labor, but not previous CD, adversely impact neonatal outcomes. Conclusion Longer S-D times are significantly associated with adverse neonatal outcomes. Factors that prolong the time interval between skin incision and delivery may or may not necessarily be associated with adverse neonatal outcomes. Considering surgical techniques that shorten the incision-delivery time and preparation for advanced neonatal care for risky subjects would help reduce detrimental neonatal consequences.

Abstract
BACKGROUND Multiple benefits for both, mother and baby have been reported from immediate skin-to-skin care (SSC). The aim of this study was to analyze the influence of SSC on operative time and blood loss in primary cesarean births for breech presentation. METHODS A SSC protocol for cesarean birth was implemented in our institution on February 25, 2019. In this single-center retrospective cohort study, we compared the outcomes of planned primary cesarean births for breech presentation at term before and after its implementation. RESULTS Data from 110 women who had a cesarean birth for breech presentation at term were analyzed, 55 in each group. Group 1 were women who had immediate SSC and Group 2 were women without immediate SSC. Maternal and surgical characteristics, and neonatal outcomes were similar in both groups. The mean operative time was 3.22 minutes shorter in the immediate SSC group compared with the not immediate SSC group (37.13 ± 12.27 vs 40.35 ± 12.23 minutes; P = 0.171). CONCLUSIONS In conclusion, immediate SSC following a low-risk cesarean birth for breech presentation neither prolongs the operative time nor increases blood loss during the procedure. Although we were unable to demonstrate a significant reduction in the operative time with the immediate SSC protocol, a decrease of 3 minutes was noted.

Abstract
BACKGROUND The French AmbUlatory Cesarean Section is a cesarean delivery technique, which includes a vertical fascial incision to the left of the linea alba and an extraperitoneal approach to the uterus. The presumed benefits of this technique are decreased postoperative pain and accelerated recovery. However, evidence supporting these impressions is scarce. OBJECTIVE This study aimed to compare maternal recovery after French AmbUlatory Cesarean Section vs standard cesarean delivery technique. STUDY DESIGN In this double-blind randomized controlled trial, women undergoing elective cesarean delivery at term were allocated into French AmbUlatory Cesarean Section vs standard cesarean delivery technique. A modified French AmbUlatory Cesarean Section technique was used, adhering to all French AmbUlatory Cesarean Section operative steps except for the extraperitoneal approach. In both groups, the use of intravenous hydration, intrathecal morphine, and bladder catheter was avoided, and all women were encouraged to stand and walk 3 to 4 hours after the operation. The primary adverse composite outcome included either of the following: a visual analog scale score of >6 at 3 to 4 hours after the operation, an inability to stand up and walk to the restroom 3 to 4 hours after the operation, and a 15-Item Quality of Recovery (QoR) questionnaire score of <90 at 24 hours after the operation. The women were followed up for 6 weeks. RESULTS Overall, 116 women were included in the trial (58 in each group). The adverse composite outcome did not differ between the 2 groups (38.9% for the French AmbUlatory Cesarean Section group vs 53.8% for the regular cesarean delivery group; P=.172). In both groups, more than 90% of the women were able to get up and walk 3 to 4 hours after the operation. Compared with the standard cesarean delivery group, the French AmbUlatory Cesarean Section group had a longer duration of the operation (43.7±11.2 vs 54.4±11.3 minutes; P<.001), a higher rate of intraoperative complications (0.0% vs 13.8%; P=.006), and a higher rate of umbilical cord pH level of <7.2 (3.4% vs 17.2%; P=.029) were noted. Evaluation via phone call 1 week after the operation showed better quality of recovery scores in the French AmbUlatory Cesarean Section group than in the standard cesarean delivery group (27.1±8.4 vs 24.6±8.0; P=.043). Other secondary outcomes did not differ between the 2 groups. CONCLUSION As excellent maternal recovery was noted in both groups, we believe that the main factor affecting this recovery is the perioperative management (including avoidance of the use of intraoperative intravenous hydration, intrathecal morphine, and bladder catheter, with early postoperative mobilization). The maternal and neonatal safety outcomes of the French AmbUlatory Cesarean Section technique remain to be proven by larger-scale high-quality randomized controlled trials.

Abstract
OBJECTIVE To evaluate whether patients with obesity who undergo scheduled cesarean delivery under neuraxial anesthesia are at increased risk for umbilical artery pH less than 7.1 and base deficit 12 mmol or greater. METHODS We conducted a multicenter, retrospective cohort study of individuals who delivered a term, singleton, nonanomalous neonate at one of four academic medical centers in New York City from 2013 to 2019 by scheduled cesarean under neuraxial anesthesia for whom fetal cord blood gas results were available. The primary study outcome was rate of fetal acidosis , defined as umbilical artery pH less than 7.1. This was compared between patients with obesity (body mass index [BMI] 30 or higher) and those without obesity (BMI lower than 30). Base deficit 12 mmol or greater and a composite of fetal acidosis and base deficit 12 mmol or greater were also compared. Secondary outcomes included neonatal intensive care unit admission rate, 5-minute Apgar score less than 7, and neonatal morbidity. Associations between maternal BMI and study outcomes were assessed using multivariable logistic or linear regression and adjusted for age, race and ethnicity, insurance type, cesarean delivery order number, and neuraxial anesthesia type. RESULTS Of the 6,264 individuals who met inclusion criteria during the study interval, 3,098 had obesity and 3,166 did not. The overall rate of umbilical artery cord pH less than 7.1 was 2.5%, and the overall rate of umbilical artery base deficit 12 mmol or greater was 1.5%. Patients with obesity were more likely to have umbilical artery cord pH less than 7.1 (adjusted odds ratio [aOR] 2.7, 95% CI 1.8-4.2) and umbilical artery base deficit 12 mmol or greater (aOR 3.2, 95% CI 1.9-5.3). This association was not significantly attenuated after additional adjustments for potential mediators, including maternal medical comorbidities. We found no differences in secondary outcomes between groups. CONCLUSION Maternal obesity is associated with increased odds of arterial pH less than 7.1 and base deficit 12 mmol or greater at the time of scheduled cesarean delivery under neuraxial anesthesia.

Abstract
OBJECTIVE The aim of this study was to examine the relationship between maternal obesity and fetal umbilical arterial pH in a cohort of parturients that received a prophylactic phenylephrine infusion for management of spinal anesthesia induced hypotension during cesarean delivery. METHODS This was a retrospective cohort study of cesarean deliveries at a single academic tertiary care institution between January 2012 and March 2019. All scheduled nonlaboring cesarean deliveries of singleton live neonate performed under spinal anesthesia between 37 and 41 weeks gestational age were included. The primary outcome was umbilical arterial pH. Multiple regression models were used to test the relationship between umbilical arterial pH, and maternal body mass index (BMI), race, dose of phenylephrine, baseline systolic blood pressure, maximum decrease in systolic blood pressure, induction of anesthesia to delivery time and uterine incision to delivery time. RESULTS Seven hundred and sixty-one mother neonate pairs were included in the study. The univariate analysis showed a decrease in mean umbilical arterial pH with increasing maternal BMI (p = <.01). A multivariate regression model indicated that maximum decrease in systolic blood pressure, induction of anesthesia to delivery time, and uterine incision to delivery time accounted for 11% of the variance in the outcome, R2 = 0.11. BMI was not a significant predictor of low umbilical arterial pH (p = .36). The significant predictors of low umbilical arterial pH in the model were maximum decrease in systolic blood pressure (p < .001), induction of anesthesia to delivery time (p = .04), and uterine incision to delivery time (p < .001). CONCLUSIONS Maternal BMI is not associated with lower umbilical arterial pH in women having scheduled cesarean delivery under spinal anesthesia. Severity of spinal anesthesia induced hypotension is greater with increasing BMI and may be responsible for the observed decrease in umbilical arterial pH.

Abstract
Objective More women are obese at their first prenatal visit and then subsequently gain further weight throughout pregnancy than ever before. The impact on the infant's development of neonatal hypoxic ischemic encephalopathy (HIE) has not been well studied. Using defined physiologic and neurologic criteria, our primary aim was to determine if maternal obesity conferred an additional risk of HIE. Study Design Data from the New York State Perinatal Data System of all singleton, term births in the Northeastern New York region were reviewed using the NIH obesity definition (Body Mass Index (BMI) ≥ 30 kg/m2). Neurologic and physiologic parameters were used to make the diagnosis of HIE. Physiologic criteria included the presence of an acute perinatal event, 10-min Apgar score ≤ 5, and metabolic acidosis. Neurologic factors included hypotonia, abnormal reflexes, absent or weak suck, hyperalert, or irritable state or evidence of clinical seizures. Therapeutic hypothermia was initiated if the infant met HIE criteria when assessed by the medical team. Logistic regression analysis was used to assess the effect of maternal body mass index on the diagnosis of HIE. Results In this large retrospective cohort study we evaluated outcomes of 97,488 pregnancies. Infants born to obese mothers were more likely to require ventilatory assistance and have a lower 5-min Apgar score. After adjusting for type of delivery and maternal risk factors, infants of obese mothers were diagnosed with HIE more frequently than infants of non-obese mothers, OR 1.96 (1.33-2.89) (p = 0.001). Conclusion Infants of obese mothers were significantly more likely to have the diagnosis of HIE.

The association of fetal acidemia with adverse neonatal outcomes at time of scheduled cesarean delivery. Am J Obstet Gynecol 2022; 227:265.e1-265.e8. [PMID: 35489441 DOI: 10.1016/j.ajog.2022.04.037] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 04/03/2022] [Accepted: 04/08/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Fetal acidemia at the time of a scheduled cesarean delivery is generally unexpected. In the setting of reassuring preoperative monitoring, the duration of fetal acidemia in this scenario is presumably brief. The neonatal sequelae and risks associated with brief fetal acidemia in this setting are unknown. OBJECTIVE We aimed to assess whether fetal acidemia at the time of a scheduled prelabor cesarean delivery is associated with adverse neonatal outcomes. STUDY DESIGN This was a retrospective cohort study of singleton, term, nonanomalous, liveborn neonates delivered by scheduled cesarean delivery that was performed under regional anesthesia from 2004 to 2014 at a single tertiary care center with a universal umbilical cord gas policy. Neonates born to laboring gravidas and those whose cesarean delivery was performed for nonreassuring fetal status were excluded. All included patients had reassuring preoperative fetal monitoring. The primary outcome was a composite adverse neonatal outcome that included neonatal death, encephalopathy, therapeutic hypothermia, seizures, intubation, and respiratory distress. This outcome was compared between patients with and those without fetal acidemia (umbilical artery pH <7.2). A multivariable logistic regression was used to adjust for confounders. Cases of fetal acidemia were further characterized as respiratory, metabolic, or mixed acidemia based on additional umbilical cord gas values. Secondary analyses examining the association between the type of acidemia and neonatal outcomes were also performed. RESULTS Of 2081 neonates delivered via scheduled cesarean delivery, 252 (12.1%) had fetal acidemia at the time of delivery. Acidemia was more common in breech neonates and in neonates born to gravidas with obesity and gestational diabetes mellitus. Compared with fetuses with normal umbilical artery pH, those with fetal acidemia were at a significantly increased risk for adverse neonatal outcome (adjusted relative risk, 2.95; 95% confidence interval, 2.03-4.12). This increased risk was similar regardless of the type of acidemia. CONCLUSION Even a brief period of mild acidemia is associated with adverse neonatal outcomes at the time of a scheduled cesarean delivery despite reassuring preoperative monitoring. Addressing modifiable intraoperative factors that may contribute to fetal acidemia at the time of a scheduled cesarean delivery, such as maternal hypotension and prolonged operative time, is an important priority to potentially decrease neonatal morbidity in full-term gestations.

Abstract
Background The incidence of placenta preiva is rising. Cesarean delivery is identified as the only safe and appropriate mode of delivery for pregnancies with placenta previa. Anesthesia is important during the cesarean delivery. The aim of this study is to assess maternal and neonatal outcomes of patients with placenta previa managed with neuraxial anesthesia as compared to those who underwent general anesthesia during cesarean delivery. Methods A retrospective cohort study was performed of all patients with placenta preiva at our large academic institution from January 1, 2014 to June 30, 2019. Patients were managed neuraxial anesthesia and general anesthesia during cesarean delivery. Results We identified 1234 patients with placenta previa who underwent cesarean delivery at our institution. Neuraxial anesthesia was performed in 737 (59.7%), and general anesthesia was completed in 497 (40.3%) patients. The mean estimated blood loss at neuraxial anesthesia of 558.96 ± 42.77 ml were significantly lower than the estimated blood loss at general anesthesia of 1952.51 ± 180 ml (p < 0.001). One hundred and forty-six of 737 (19.8%) patients required blood transfusion at neuraxial anesthesia, whereas 381 out of 497 (76.7%) patients required blood transfusion at general anesthesia. The rate neonatal asphyxia and admission to NICU at neuraxial anesthesia was significantly lower than general anesthesia (2.7% vs. 19.5 and 18.2% vs. 44.1%, respectively). After adjusting confounding factors, blood loss was less, Apgar score at 1- and 5-min were higher, and the rate of blood transfusion, neonatal asphyxia, and admission to NICU were lower in the neuraxial group. Conclusions Our data demonstrated that neuraxial anesthesia is associated with better maternal and neonatal outcomes during cesarean delivery in women with placenta previa.

Abstract
OBJECTIVE To assess whether a history of prior cesarean delivery is associated with an increased risk of earlier delivery timing and resultant neonatal morbidity. METHODS We performed a population-based retrospective cohort study using U.S. birth certificate data, 2012-2016. The study population included women with one or more prior cesarean deliveries compared with a referent group of parous women without prior cesarean delivery. To enrich for a population with minimized risk factors for early delivery, we excluded women with history of preterm birth, pregnancies complicated by multifetal gestation, pregnancy-induced hypertension, anomaly, small for gestational age, or malpresentation. Analyses were limited to births from 35 to 42 weeks of gestation. Women with a vaginal birth after cesarean delivery were excluded. The primary outcome was the risk of birth at each week of gestational age. Secondary outcomes included adverse neonatal and maternal outcomes. RESULTS Patients were stratified by number of prior cesarean deliveries (one, two, three, or four or more) compared with parous patients without prior cesarean delivery. The adjusted relative risk (aRR) of delivery at 35 weeks of gestation was highest in women with four or more prior cesarean deliveries (aRR 2.79, 95% CI 2.74-2.82). Prior cesarean delivery also had a significant influence on neonatal morbidity. As the number of prior cesarean deliveries increased, the risk of composite neonatal morbidity increased, from 8.0% (aRR 1.5, 95% CI 1.48-1.51) with one prior cesarean delivery up to 21.0% (aRR 4.9, 95% CI 4.76-5.04) with four or more prior cesarean deliveries compared with a baseline risk of 5.5% in parous women without prior cesarean delivery. CONCLUSION Prior cesarean delivery is correlated with earlier delivery and increased neonatal morbidity. Advocating trial of labor after cesarean delivery may provide maternal and neonatal benefit.

Abstract
The optimal intrathecal dose of local anaesthetic for caesarean section (CS) anaesthesia is still being debated. We performed a study to compare the effectiveness and safety of spinal anaesthesia with 12.5 mg of hyperbaric bupivacaine and a dosing regimen of conventional doses adjusted to parturient height. One hundred and forty parturients scheduled for elective CS were enrolled. The fixed-dose group (FD) received a spinal block with 12.5 mg of hyperbaric bupivacaine with fentanyl, whereas the adjusted-dose group (AD) received a height-adjusted dose of bupivacaine (9-13 mg) with fentanyl. Sensory block ≥ T5 dermatome within 10 min and no need for supplementary analgesia were set as the composite primary outcome (success). Rates of successful blocks and complications were compared. Complete data were available for 134 cases. Spinal anaesthesia was successful in 58 out of 67 patients in the FD group and 57 out of 67 in the AD group (p > 0.05). Eight spinals in each group failed to produce a block ≥ T5 in 10 min, and one patient in the FD group and two in the AD group required i.v. analgesics despite sensory block ≥ T5. No differences were noted in terms of hypotension, bradycardia and nausea between the FD and AD groups. Compared to the height-adjusted dose regimen based on conventional doses of hyperbaric bupivacaine, the fixed dose regimen of 12.5 mg was equally effective and did not increase the risk of spinal block-related complications.

Am J Obstet Gynecol 2020; 223:747.e1-747.e13.

Abstract
BACKGROUND Maternal hypotension after spinal anesthesia, and time from anesthesia to delivery, are potentially modifiable risk factors for neonatal acidosis. OBJECTIVE This study aimed to examine the relationship between the time from spinal anesthesia to delivery and spinal hypotension in planned cesarean deliveries and their effect on neonatal outcome, primarily neonatal acidosis. STUDY DESIGN We performed a retrospective analysis of women with singleton pregnancy undergoing spinal anesthesia for planned cesarean delivery between 37 0/7 and 41 6/7 weeks' gestation using electronic medical records. The occurrence of spinal hypotension and anesthesia-to-incision and incision-to-delivery intervals (minutes) were the primarily studied variables. In addition, spinal hypotension index was developed to account for the duration and magnitude of maternal hypotension. The 90th percentile for the spinal hypotension index defined the sustained spinal hypotension group. The primary outcome was neonatal acidosis (pH of ≤7.1 or base deficit of ≥12.0). The odds ratios were calculated using univariate and multivariate logistic regression models. The multivariate analysis included sporadic spinal hypotension or sustained spinal hypotension, use of vasopressor treatment, and anesthesia-to-incision and incision-to-delivery intervals. RESULTS We included 3150 women in the study. Notably, 43.4% experienced at least 1 event of spinal hypotension (sporadic) and 14.8% experienced sustained spinal hypotension. Neonatal acidosis occurred in 3.4% cases of sporadic spinal hypotension (odds ratio, 1.83; 95% confidence interval, 2.27-2.87) and in 5.8% cases of sustained hypotension (odds ratio, 3.00; 95% confidence interval, 1.87-4.80). Both anesthesia-to-incision and incision-to-delivery intervals were significantly associated with neonatal acidosis as follows: at 90th percentile cutoff, the odds ratios for neonatal acidosis were 3.82 (95% confidence interval, 2.03-7.19) and 2.94 (95% confidence interval, 1.70-5.10), respectively. The use of ephedrine (odds ratio, 2.42; 95% confidence interval, 1.35-4.32) but not phenylephrine (odds ratio, 0.76; 95% confidence interval, 0.34-1.72) treatment was also associated with more cases of neonatal acidosis. The woman's age, gestational age, neonatal birthweight, fetal presentation, and the number of previous cesarean deliveries were not associated with neonatal acidosis. In multivariate analysis, anesthesia-to-incision and incision-to-delivery intervals, use of vasopressor treatment, and sustained spinal hypotension were independently associated with neonatal acidosis. After adjustment, the risk for neonatal acidosis did not increase in women who experienced sporadic spinal hypotension only. Neither neonatal acidosis nor the primary research variables were associated with neonatal complications such as transient tachypnea of the newborn, respiratory distress, or admission to the neonatal unit. CONCLUSION Neonatal acidosis in planned cesarean delivery was common. However, serious perinatal consequences were rare. The adverse effects of sustained spinal hypotension and prolonged anesthesia-to-incision and incision-to-delivery intervals on neonatal acid-base balance were additive. This supports the adoption of prevention strategies for spinal hypotension, which is widely evidenced based on the obstetrical anesthesia literature, but still not universally used. Whether the reduction in intraoperative time intervals would benefit the neonate should be determined by future prospective studies.

Abstract
Using a cephalic elevation device during second-stage cesarean deliveries decreases time to delivery after hysterotomy by 23 seconds. A cephalic elevation device is an inflatable device that elevates the fetal head. We sought to evaluate whether such a device reduces time to delivery after hysterotomy and lowers morbidity in cesarean deliveries during the second stage of labor.

Abstract
INTRODUCTION The covid-19 pandemic has meant a change in working protocols, as well as in Personal Protective Equipment (PPE). Obstetricians have had to adapt quickly to these changes without knowing how they affected their clinical practice. The aim of the present study was to evaluate how COVID-19 pandemic and PPE can affect operative time, operating room time, transfer into the operating room to delivery time and skin incision to delivery time in cesarean section. METHODS This is a single-center retrospective cohort study. Women with confirmed or suspected SARS-CoV-2 infection having a cesarean section after March 7th, 2020 during the COVID-19 pandemic were included in the study. For each woman with confirmed or suspected SARS-CoV-2 infection, a woman who had a cesarean section for the same indication during the COVID-19 pandemic and with similar clinical history but not affected by SARS-CoV-2 was included. RESULTS 42 cesarean sections were studied. The operating room time was longer in the COVID-19 confirmed or suspected women: 90 (73.0 to 110.0) versus 61 (48.0 to 70.5) minutes; p < .001. The transfer into the operating room to delivery time was longer, but not statistically significant, in urgent cesarean sections in COVID-19 confirmed or suspected women: 25.5 (17.5 to 31.75) versus 18.0 (10.0 to 26.25) minutes; p = .113. CONCLUSIONS There were no significant differences in the operative time, transfer into the operating room to delivery time and skin incision to delivery time when wearing PPE in cesarean section. The COVID-19 pandemic and the use of PPE resulted in a significant increase in operating room time.
