Randomized Controlled Trial Comparative Study Clinical TrialComparison of continuous background infusion plus demand dose and demand-only parturient-controlled epidural analgesia (PCEA) using ropivacaine combined with sufentanil for labor and delivery.
Using ropivacaine combined with sufentanil, we determined the analgesic efficacy of parturient-controlled epidural analgesia (PCEA) with or without (demand-only PCEA) continuous background infusion in reducing labor pain in 66 parturients. ⋯ Under the conditions of the study, PCEA plus continuous background infusion was more effective than demand-only PCEA in treating labor pain without increasing consumption of anesthetic solution.

Randomized Controlled Trial Clinical TrialIntrathecal epinephrine in combined spinal-epidural analgesia for labor: dose-response relationship for epinephrine added to a local anesthetic-opioid combination.
The purpose was to investigate the dose-response relationship for intrathecally administered epinephrine added to a local anesthetic-opioid combination in combined spinal-epidural analgesia for labor, in order to evaluate analgesia and side-effects. ⋯ The results suggest that adding epinephrine to a combination of standard intrathecal doses of bupivacaine and fentanyl in combined spinal-epidural analgesia for labor significantly prolongs spinal analgesia. Of the four epinephrine doses tested, the lowest one (12.5 microg) was optimal for this clinical setting.

A prospective observational study of the use of the Proseal laryngeal mask airway for postpartum tubal ligation.
Though controversial, the risk of pulmonary aspiration during general anaesthesia in the immediate postpartum period appears low. The efficacy of the Proseal laryngeal mask airway was studied prospectively in a group of patients undergoing postpartum tubal ligation. ⋯ The Proseal laryngeal mask airway provides an effective airway for general anaesthesia in fasted patients undergoing tubal ligation from 8 h after normal vaginal delivery. While the safety of an unprotected airway in this population remains uncertain, this study suggested a low risk of regurgitation, especially in the first 24 h post partum.

Maternal and fetal outcome of anaesthesia for caesarean delivery in preeclampsia/eclampsia in Enugu, Nigeria: a retrospective observational study.
Maternal mortality, for which preeclampsia is a major cause, is a problem in Nigeria. Accurate data are available for caesarean sections in the University of Nigeria Teaching Hospital, Enugu. We therefore studied the outcome of caesarean section among these high-risk patients. ⋯ Maternal and fetal mortality were high. Poverty, late presentation, lack of equipment and inexperienced management were major contributory factors. Use of spinal anaesthesia should be encouraged in view of recent favourable reviews and cheaper cost.
