Labor Epidural Analgesia to Cesarean Section Anesthetic Conversion Failure: A National Survey.

ABSTRACT:

Background

If 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.

Method

All 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.

Results

We 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.

Discussion

Our 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:Background:The rationale for injection of epidural medications through the needle is to promote sooner onset of pain relief relative to dosing through the epidural catheter given that needle injection can be performed immediately after successful location of the epidural space. Some evidence indicates that dosing medications through the epidural needle results in faster onset and improved quality of epidural anesthesia compared to dosing through the catheter, though these dosing techniques have not been compared in laboring women. This investigation was performed to determine whether dosing medication through the epidural needle improves the quality of analgesia, level of sensory blockade, or onset of pain relief measured from the time of epidural medication injection. Methods:In this double-blinded prospective investigation, healthy term laboring women (n=60) received labor epidural placement upon request. Epidural analgesia was initiated according to the assigned randomization group: 10 mL loading dose (0.125% bupivacaine with fentanyl 2 µg/mL) through either the epidural needle or the catheter, given in 5 mL increments spaced 2 minutes apart. Verbal rating scale (VRS) pain scores (0-10) and pinprick sensory levels were documented to determine the rates of analgesic and sensory blockade onset. Results:No significant differences were observed in onset of analgesia or sensory blockade from the time of injection between study groups. The estimated difference in the rate of pain relief (VRS/minute) was 0.04 (95% CI: -0.01 to 0.11; p=0.109), and the estimated difference in onset of sensory blockade (sensory level/minute) was 0.63 (95% CI: -0.02 to 0.15; p=0.166). The time to VRS ?3 and level of sensory block 20 minutes after dosing were also similar between groups. No differences in patient satisfaction, or maternal or fetal complications were observed. Conclusion:This investigation observed that epidural needle and catheter injection of medications result in similar onset of analgesia and sensory blockade, quality of labor analgesia, patient satisfaction, and complication rates.

Project description:ImportanceA recent cohort study found that epidural analgesia during labor was associated with an increased risk of autism in offspring.ObjectiveTo investigate if labor epidural increases the risk of autism in offspring.Design, setting, and participantsThis nationwide retrospective cohort study identified all live-born children in Denmark between January 2006 and December 2013. Follow-up commenced at children's first birthday and ended in December 2017. Among 485 093 live-born children, 5915 were excluded because of occurrences during the first year of life including death, emigration, misregistration of birth, diagnosis of disease inherently linked to autism, or diagnosis of autism.ExposuresAdministration of epidural analgesia during labor, as identified by procedure code.Main outcomes and measuresThe main outcome of interest was incident diagnosis of autism spectrum disorder based on International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes in the Danish Psychiatric Central Register or National Patient Register. Hazard ratios were estimated using Cox regression, adjusted for covariates describing maternal comorbidity, sociodemographic factors, lifestyle, pregnancy, psychiatric illness, psychotropic medication, medical-seeking behavior, and family history of autism. A secondary analysis used a within-mother design including only children of mothers with both exposure and nonexposure to labor epidural analgesia in different deliveries.ResultsThe cohort included 479 178 children (233 405 girls [48.7%]; median maternal age at delivery, 30.9 [IQR, 27.6-34.2] years); of these, 92 900 (19.4%) were exposed to epidural analgesia during labor. Median follow-up was 7.0 years (IQR, 4.9-9.0 years), and by the end of follow-up, 6428 children (1.3%) had been diagnosed with autism. Exposed children had an autism diagnosis incidence rate of 23.1 per 10 000 person-years compared with 18.5 per 10 000 person-years in the unexposed group (crude hazard ratio, 1.29 [95% CI, 1.21-1.37]; adjusted hazard ratio, 1.05 [95% CI, 0.98-1.11]). A secondary within-mother analysis including 59 154 children (12.3%) estimated an autism diagnosis incidence rate of 20.8 per 10 000 person-years in the exposed group and 17.1 per 10 000 person-years in the unexposed group (adjusted hazard ratio, 1.05 [95% CI, 0.90-1.21]).Conclusions and relevanceIn this nationwide cohort study of Danish children, maternal exposure to epidural analgesia during labor was not significantly associated with autism spectrum disorder in offspring.

Project description:ObjectiveChina has a high cesarean delivery (CD) and low labor epidural analgesia (LEA) rate. This online survey was conducted to explore the reasons behind this phenomenon and potential solutions.MethodsA voluntary, anonymous survey was distributed via both WeChat and professional websites for 4 months amongst groups of Chinese perinatal professionals. Data was collected and analyzed using a Chi-square test and presented as percentages of respondents.Results1412 respondents were recorded (43% anesthesiologists, 35% obstetricians, 15.5% midwives or labor and delivery nurses, and 6.5% others), and 1320 respondents were care providers. It was found that 82.7% (1092/1320) of the provider respondents used CD per patient request in fear of lawsuits or yinao/yibao and 63.4% (837/1320) used CD for respecting superstitious culture. The number one reason (noted by 60.2% (795/1320) of all the three specialties) for low LEA use was lack of anesthesia manpower without statistical difference among specialties. The most recommended solution was increasing the anesthesia workforce, proposed by 79.8% (1053/1320) of the three specialties. However, the top solution provided by the two non-anesthesia specialties is different from the one proposed by anesthesiologists. The later (83%, 504/606) suggested increasing the incentive to provide the service is more effective. The answers to questions related to medical knowledge about CD and LEA, and unwillingness of anesthesiologists, parturients and their family members to LEA were similar for the most part, while the opinions regarding low LEA use related to poor experiences and unwillingness of obstetricians and hospital administrators were significantly divided among the three specialties. In the providers' point of view, the unwillingness to LEA from parturient's family members was the most salient (26.1%, 345/1320), which is more than all care providers, hospital administrators, and parturients themselves (16.8%, 222/1320).ConclusionThe reasons for high CD rate and low LEA use are multifactorial. The sociological issues (fear of yinao/yibao and superstitious culture) were the top two contributing factors for the high CD rate in China, while lack of anesthesia manpower was the top response for the low LEA use, which contributes to its being the most recommended solution overall from the three specialties. An incentive approach to providers is a short-term solution while training more perinatal care providers (especially among anesthesiologists and midwives), improving billing systems, and reforming legal systems are 3 systemic approaches to tackling this problem in the long-term.
