Ontology highlight
ABSTRACT: Aim
This study aimed to examine the association between clinically diagnosed chorioamnionitis and failed conversion of epidural labor analgesia to cesarean delivery anesthesia.Methods
This retrospective, single-center cohort study, conducted in a university hospital, enrolled term parturients undergoing emergency cesarean section after induction of epidural labor analgesia between September 2015 and May 2019. For the purpose of this study, all cases were re-examined to ensure that they fulfilled the criteria of chorioamnionitis, regardless of the actual indication for cesarean section proposed by obstetricians at the time of application. The primary outcome was failure of conversion of epidural labor analgesia to cesarean delivery anesthesia. Multivariable logistic regression analysis was performed to investigate the association between chorioamnionitis and failure of anesthesia for cesarean section.Results
Among the 180 parturients reviewed, 58 (43.9%) fulfilled the criteria for chorioamnionitis. Failure of epidural conversion in the chorioamnionitis (+) group was significantly higher than in the chorioamnionitis (-) group (46.6% [27/58] vs. 18.9% [14/74], crude odds ratio = 3.7, 95% confidence interval: 1.7-8.3). After adjustment for potential confounders (age, body mass index, multiparity, and duration for epidural labor analgesia), chorioamnionitis was found to be associated with failure of anesthesia for cesarean sections (adjusted odds ratio = 3.6, 95% confidence interval: 1.6-8.4).Conclusions
Chorioamnionitis is associated with the failed conversion of epidural labor analgesia to cesarean delivery anesthesia.

Project description:BackgroundIf conversion of labor epidural analgesia to cesarean delivery anesthesia fails, the anesthesiologist can be confronted with a challenging clinical dilemma. Optimal management of a failed epidural top up continues to be debated in the absence of best practice guidelines.MethodAll members of the Obstetric Anaesthetists' Association in the United Kingdom were emailed an online survey in May 2017. It obtained information on factors influencing the decision to utilize an existing labor epidural for cesarean section and, if epidural top up resulted in no objective sensory block, bilateral T10 sensory block, or unilateral T6 sensory block, factors influencing the management and selection of anesthetic technique. Differences in management options between respondents were compared using the chi-squared test.ResultsWe received 710 survey questionnaires with an overall response rate of 41%. Most respondents (89%) would consider topping up an existing labor epidural for a category-one cesarean section. In evaluating whether or not to top up an existing labor epidural, the factors influencing decision-making were how effective the epidural had been for labor pain (99%), category of cesarean section (73%), and dermatomal level of blockade (61%). In the setting of a failed epidural top up, the most influential factors determining further anesthetic management were the category of cesarean section (92%), dermatomal level of blockade (78%), and the assessment of maternal airway. Spinal anesthesia was commonly preferred if an epidural top up resulted in no objective sensory block (74%), bilateral T10 sensory block (57%), or unilateral T6 sensory block (45%). If the sensory block level was higher or unilateral, then a lower dose of intrathecal local anesthetic was selected and alternative options such as combined-spinal epidural and general anesthesia were increasingly favored.DiscussionOur survey revealed variations in the clinical management of a failed epidural top up for cesarean delivery, suggesting guidelines to aid decision-making are needed.

Project description:The conversion of epidural labor analgesia (ELA) to epidural surgical anesthesia (ESA) for intrapartum cesarean section (CS) often fails, resulting in intraoperative pain. Spinal anesthesia (SA) can provide a denser sensory block than ESA. The purpose of this prospective, non-blinded, parallel-arm, randomized trial was to compare the rate of pain-free surgery between ESA and SA following ELA for intrapartum CS.Both groups received continuous epidural infusions for labor pain at a rate of 10 ml/h. In the ESA group (n = 163), ESA was performed with 17 ml of 2% lidocaine mixed with 100 µg fentanyl, 1 : 200,000 epinephrine, and 2 mEq bicarbonate. In the SA group (n = 160), SA was induced with 10 mg of 0.5% hyperbaric bupivacaine and 15 µg fentanyl. We investigated the failure rate of achieving pain-free surgery and the incidence of complications between the two groups.The failure rate of achieving pain-free surgery was higher in the ESA group than the SA group (15.3% vs. 2.5%, P < 0.001). There was no statistical difference between the two groups in the rate of conversion to general anesthesia; however, the rate of analgesic requirement was higher in the ESA group than in the SA group (12.9% vs. 1.3%, P < 0.001). The incidence of high block, nausea, vomiting, hypotension, and shivering and Apgar scores were comparable between the two groups.SA after ELA can lower the failure rate of pain-free surgery during intrapartum CS compared to ESA after ELA.

Project description:BackgroundBreastfeeding is essential for infants and mothers. Epidural labor analgesia is used frequently to alleviate pain during vaginal delivery. Studies have found that epidural labor analgesia potentially have negative effects on postpartum breastfeeding. However, the efficacy of epidural labor analgesia on early breastfeeding after vaginal delivery is unclear. Therefore, a retrospective analysis was performed to illuminate the efficacy of epidural labor analgesia on postpartum breast feeding.MethodsA total of 392 women who received vaginal delivery in the Second People's Hospital of Foshan from July 2022 to June 2023 were selected for this study, and all women received epidural labor analgesia and were divided into three groups according to the efficacy of labor analgesia. There were three groups: parturients with VAS scores < 3 were divided into Group E (n = 192), parturients with VAS scores 4-6 were divided into Group M (n = 127), and parturients with VAS scores > 7 were divided into Group P (n = 73). The labor process, lactation initiation time, and incidence of delayed onset of lactation were analyzed. The lactation volume and time and LATCH score at 24, 48 and 72 h after vaginal delivery were also analyzed.ResultsThere was no significant difference in labor process times among the three groups (P > 0.05). The cases of prolactin use in Group M were less than those in Group E and Group P, with a significant difference (all P < 0.05). There was no significant difference in cases of prolactin use between Group E and Group P (P > 0.05). The lactation initiation time in Group M was significantly shorter than those in Group E and Group P (all P>0.05). There was no significant difference in lactation initiation time after vaginal delivery between Group E and Group P (P>0.05). The incidence of delayed onset of lactation in Group M was significantly lower those that in Group E and Group P (all P < 0.05). There was no statistically significant difference in the incidence of delayed onset of lactation between Group E and Group P (P > 0.05). The lactation volumes at 24, 48 and 72 h after vaginal delivery in Group M were significantly higher than those in Group E and Group P (all P < 0.05). There was no significant difference in lactation volume at 24, 48 and 72 h after vaginal delivery between Group E and Group P (P > 0.05). The lactation times at 24, 48 and 72 h after vaginal delivery in Group M were significantly higher than those in Group E and Group P (all P < 0.05). There was no significant difference in lactation times at 24, 48 and 72 h after vaginal delivery between Group E and Group P (P > 0.05). There was no significant difference in LATCH scores at 24, 48 and 72 h after vaginal delivery among the three groups (all P > 0.05).ConclusionsCompared with labor analgesia with excellent and poor analgesia efficacy, labor analgesia with moderate analgesia efficacy has fewer cases of prolactin use, more lactation volume and time, a shorter lactation initiation time, a lower incidence of delayed onset of lactation and no effect on the LATCH score of breastfeeding.

Project description:BackgroundThis study aimed to investigate the effect of the pathological staging of acute histological chorioamnionitis (HCA) on laboratory indicators and to conduct further studies to reassess the threshold values used by clinicians to identify acute HCA in febrile parturients undergoing epidural analgesia.MethodsA retrospective study of febrile mothers receiving epidural analgesia at Nanjing Maternal and Child Health Care Hospital from January 1, 2018 to December 31, 2018. The participants were grouped by the progression of acute HCA, and the laboratory parameters were compared between groups. The ability of C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and monocyte-leukocyte ratio (M%), alone or in combination, to identify acute HCA in febrile parturients undergoing epidural analgesia was assessed using logistic regression and ROC curves.ResultsThe area under the curve (AUC) of the best logistic regression model predicting HCA climbed to 0.706 (CRP + MLR). Maternal CRP, NLR, and MLR significantly and progressively increased with the progression of acute HCA (p < 0.0001). Based on the ROC curves, the following thresholds were selected to define increased laboratory indicators for identifying acute HCA: CRP ≥ 6.90 mg/L, NLR ≥ 11.93, and MLR ≥ 0.57. In addition, the AUC of the best logistic regression model predicting HCA ≥ stage 2 was 0.710, so these inflammatory markers were more precise in predicting HCA ≥ stage 2.ConclusionIncreased CRP (≥ 6.90 mg/L), NLR (≥ 11.93), and MLR (≥ 0.57) may help clinicians to identify early potential acute HCA in febrile parturients receiving epidural analgesia and to monitor progression to optimize clinical treatment options.Trial registrationThe study was registered in the Chinese Clinical Trial Registry on November 24, 2021 ( http://www.chictr.org.cn , ChiCTR2100053554).

Project description:ImportanceEvidence from studies investigating the association of epidural analgesia use during labor and delivery with risk of autism spectrum disorder (ASD) in offspring is conflicting.ObjectiveTo assess the association of maternal use of epidural analgesia during labor and delivery with ASD in offspring using a large population-based data set with clinical data on ASD case status.Design, setting, and participantsThis population-based retrospective cohort study included term singleton children born in British Columbia, Canada, between April 1, 2000, and December 31, 2014. Stillbirths and cesarean deliveries were excluded. Clinical ASD diagnostic data were obtained from the British Columbia Autism Assessment Network and the British Columbia Ministry of Education. All children were followed up until clinical diagnosis of ASD, death, or the study end date of December 31, 2016.ExposuresUse of epidural analgesia during labor and delivery.Main outcomes and measuresA clinical diagnosis of ASD made by pediatricians, psychiatrists, and psychologists with specialty training to assess ASD. Cox proportional hazards models were used to estimate the hazard ratio of epidural analgesia use and ASD. Models were adjusted for maternal sociodemographics; maternal conditions during pregnancy; labor, delivery, and antenatal care characteristics; infant sex; gestational age; and status of small or large for gestational age. A conditional logistic regression model matching women with 2 births or more and discordance in ASD status of the offspring also was performed.ResultsOf the 388 254 children included in the cohort (49.8% female; mean gestational age, 39.2 [SD, 1.2] weeks; mean follow-up, 9.05 [SD, 4.3] years), 5192 were diagnosed with ASD (1.34%) and 111 480 (28.7%) were exposed to epidural analgesia. A diagnosis of ASD was made for 1710 children (1.53%) among the 111 480 deliveries exposed to epidural analgesia (94 157 women) vs a diagnosis of ASD in 3482 children (1.26%) among the 276 774 deliveries not exposed to epidural analgesia (192 510 women) (absolute risk difference, 0.28% [95% CI, 0.19%-0.36%]). The unadjusted hazard ratio was 1.32 (95% CI, 1.24-1.40) and the fully adjusted hazard ratio was 1.09 (95% CI, 1.00-1.15). There was no statistically significant association of epidural analgesia use during labor and delivery with ASD in the within-woman matched conditional logistic regression (839/1659 [50.6%] in the exposed group vs 1905/4587 [41.5%] in the unexposed group; fully adjusted hazard ratio, 1.07 [95% CI, 0.87-1.30]).Conclusions and relevanceIn this population-based study, maternal epidural analgesia use during labor and delivery was associated with a small increase in the risk of autism spectrum disorder in offspring that met the threshold for statistical significance. However, given the likelihood of residual confounding that may account for the results, these findings do not provide strong supporting evidence for this association.

Project description:BackgroundFew studies have systematically addressed the role of epidural analgesia and caesarean delivery in predicting the post-partum disease activity in women with Multiple Sclerosis (MS).The objective of this study was to assess the impact of epidural analgesia (EA) and caesarean delivery (CD) on the risk of post-partum relapses and disability in women with MS.MethodsIn the context of an Italian prospective study on the safety of immunomodulators in pregnancy, we included pregnancies occurred between 2002 and 2008 in women with MS regularly followed-up in 21 Italian MS centers. Data were gathered through a standardized, semi-structured interview, dealing with pregnancy outcomes, breastfeeding, type of delivery (vaginal or caesarean) and EA. The risk of post-partum relapses and disability progression (1 point on the Expanded Disability Status Sclae, EDSS, point, confirmed after six months) was assessed through a logistic multivariate regression analysis.ResultsWe collected data on 423 pregnancies in 415 women. Among these, 349 pregnancies resulted in full term deliveries, with a post-partum follow-up of at least one year (mean follow-up period 5.5±3.1 years). One hundred and fifty-five patients (44.4%) underwent CD and 65 (18.5%) EA. In the multivariate analysis neither CD, nor EA were associated with a higher risk of post-partum relapses. Post-partum relapses were related to a higher EDSS score at conception (OR=1.42; 95% CI 1.11-1.82; p=0.005), a higher number of relapses in the year before pregnancy (OR=1.62; 95% CI 1.15-2.29; p=0.006) and during pregnancy (OR=3.07; 95% CI 1.40-6.72; p=0.005). Likewise, CD and EA were not associated with disability progression on the EDSS after delivery. The only significant predictor of disability progression was the occurrence of relapses in the year after delivery (disability progression in the year after delivery: OR= 4.00; 95% CI 2.0-8.2; p<0.001; disability progression over the whole follow-up period: OR= 2.0; 95% CI 1.2-3.3; p=0.005).ConclusionsOur findings, show no correlation between EA, CD and postpartum relapses and disability. Therefore these procedures can safely be applied in MS patients. On the other hand, post-partum relapses are significantly associated with increased disability, which calls for the need of preventive therapies after delivery.

Project description:BackgroundThe epidural pressure is pulsatile and synchronized with arterial pulsations. Monitoring the epidural waveform has been suggested as a technique to reliably confirm the appropriate localization of the epidural catheter.ObjectiveThe aim of this study was to evaluate the sensitivity and specificity of the Computer Controlled Drug Delivery System with continuous pressure and waveform sensing technology (CCDDS) (CompuFlo® CathCheck™) as an instrument to assess the correct placement of the catheter in the epidural space in parturients who have received combined spinal-epidural technique (CSE) for labor analgesia.MethodsWe enrolled 40 consecutive healthy patients undergoing CSE labor analgesia with successful analgesia. All the cases in which pulsatile waveforms in synchrony with heart rate were detected were considered to be true positives; all the cases in which there was the absence of pulsatile waves were followed up. If these patients had to eventually relocate or manipulate the epidural catheter, they were considered to be true negative. If the absence of pulse waves was observed in the presence of successful analgesia during labor, the patients were considered to be false negatives.ResultsPulsatile waveforms synchronous with heart rate were observed in 33 cases associated with adequate analgesia. In 5 cases, the pulsatile waveforms were absent due to unilateral analgesia or catheter occlusion (true negatives). In 2 cases, the patients had effective analgesia but we were not able to observe a distinct pulsatile waveform. The pressure waveform analysis through the epidural catheter had a sensitivity of 95%, a positive predictive value of 100%, a specificity of 100% and a negative predictive value of 60%.ConclusionPulsatile pressure waveform recording with CCDDS through the epidural catheter resulted in high sensitivity and positive predictive value which can help the proper placement of the epidural catheter.

Project description:ImportanceDural-puncture epidural (DPE) and standard epidural are common modes of neuraxial labor analgesia. Little is known about conversion of DPE-initiated labor analgesia to surgical anesthesia for cesarean delivery.ObjectiveTo determine whether DPE provides a faster onset and better-quality block compared with the standard epidural technique for cesarean delivery.Design, setting, and participantsThis double-blind, randomized clinical trial was conducted between April 2019 and October 2022 at a tertiary care university hospital (University of Arkansas for Medical Sciences). Participants included women aged 18 years and older undergoing scheduled cesarean delivery with a singleton pregnancy.InterventionsParticipants were randomized to receive DPE or standard epidural in the labor and delivery room. A T10 sensory block was achieved and maintained using a low concentration of bupivacaine with fentanyl through the epidural catheter until the time of surgery. Epidural extension anesthesia was initiated in the operating room.Main outcomes and measuresThe primary outcome was the time taken from chloroprocaine administration to surgical anesthesia (T6 sensory block). The secondary outcome was the quality of epidural anesthesia, as defined by a composite of the following factors: (1) failure to achieve a T10 bilateral block preoperatively in the delivery room, (2) failure to achieve a surgical block at T6 within 15 minutes of chloroprocaine administration, (3) requirement for intraoperative analgesia, (4) repeat neuraxial procedure, and (5) conversion to general anesthesia.ResultsAmong 140 women (mean [SD] age, 30.1 [5.2] years), 70 were randomized to the DPE group, and 70 were randomized to the standard epidural group. The DPE group had a faster onset time to surgical anesthesia compared with the standard epidural group (median [IQR], 422 [290-546] seconds vs 655 [437-926] seconds; median [IQR] difference, 233 [104-369] seconds). The composite rates of lower quality anesthesia were 15.7% (11 of 70 women) in the DPE group and 36.3% (24 of 66 women) in the standard epidural group (odds ratio, 0.33; 95% CI, 0.14-0.74; P = .007).Conclusions and relevanceAnesthesia initiated following a DPE technique resulted in faster onset and improved block quality during epidural extension compared with initiation with a standard epidural technique. Further studies are needed to confirm these findings in the setting of intrapartum cesarean delivery.Trial registrationClinicalTrials.gov Identifier: NCT03915574.

Project description:OBJECTIVE:This report aimed to describe the characteristics and impact of subdural hematoma (SDH) after labor epidural analgesia. CASE REPORTS:Eleven obstetric patients had SDHs associated with the use of labor epidural analgesia over 7 years at a tertiary care hospital. Ten of 11 patients had signs consistent with postdural puncture headache before the diagnosis of SDH. Five patients (45%) had a recognized unintentional dural puncture, 1 (9%) had a combined spinal-epidural with a 24-gauge needle, and 5 (45%) had no recognized dural puncture. For 10 of the 11 cases, SDH was diagnosed at a mean of 4.1 days (range, 1-7 days) after performance of labor epidural analgesia; one case was diagnosed at 25 days. Ten (91%) of 11 cases had a second hospital stay for a mean of 2.8 days (range, 2-4 days) for observation, without further requirement for neurosurgical intervention. One case (9%) had decompressive hemicraniectomy after becoming unresponsive. The observed rate of labor epidural analgesia-associated SDH was 0.026% (11 in 42,969, approximately 1:3900), and the rate of SDH was 1.1% (5 in 437, approximately 1:87) if a recognized dural puncture occurred during epidural catheter placement. CONCLUSIONS:Subdural hematoma after labor epidural anesthesia is rare but potentially more common than historically estimated. Cases of postdural puncture headache after labor epidural anesthesia should be monitored closely for severe neurologic signs and symptoms that could herald SDH.
