Complications of obstetric epidural analgesia and anaesthesia: a prospective analysis of 10,995 cases.
Although epidural anaesthesia and analgesia are widely used in obstetrics, there are no large contemporary prospective series detailing associated complications. Prospective data was collected on all obstetric epidural blocks performed for labour and delivery in a single institution between July 1989 and August 1994. A data entry sheet was compiled and entered onto a computer database. ⋯ There was no major local anaesthetic toxicity or neurological deficit. The incidence of potentially life-threatening morbidity was thus 0.02% although in both cases outcome was good. The only persisting complication was neurological, an apparent epidural catheter-induced traumatic mononeuropathy.

Randomized Controlled Trial Clinical TrialEpidural lidocaine for cesarean delivery of the distressed fetus.
Lidocaine with epinephrine and sodium bicarbonate has a rapid onset of action. We therefore wished to compare its use with that of chloroprocaine for urgent cesarean delivery. Thirty parturients for cesarean section under epidural anesthesia were divided into three groups. ⋯ Lidocaine was detectable in maternal serum from four of the urgent cases and all of the elective cases. It was detectable in five neonates from the elective group but none from the emergency group. In parturients with preexisting epidural catheters and a baseline epidural infusion to maintain a T10 sensory level, chloroprocaine is faster in onset than lidocaine, but the difference in this study was only 1.3 min, and both agents provided excellent anesthesia.

Randomized Controlled Trial Clinical TrialAnaesthesia for caesarean delivery: low-dose epidural bupivacaine plus fentanyl.
To determine the acceptability of epidural bupivacaine-induced sixth thoracic (T6) sensory blockade and the analgesic efficacy of epidural fentanyl 50 microg, 24 parturients undergoing elective caesarean section were given a test dose of lidocaine 60 mg plus epinephrine followed by 10 ml of either 0.5 % bupivacaine (control group) or 0.5 % bupivacaine plus 50 microg fentanyl (fentanyl group) in a randomized double-blind manner. Fifteen minutes later loss of pinprick sensation was determined. Additional local anaesthetic was titrated to achieve T6 sensory blockade. ⋯ The incidence of side-effects was unaffected by treatment group. Apgar scores were similar in the two groups. We conclude that following administration of 10-15 ml 0.5% bupivacaine plus fentanyl 50 microg, T6 sensory blockade is associated with good intraoperative analgesia without obvious maternal or neonatal respiratory depression.
