Randomized Controlled TrialHemodynamic effects of a right lumbar-pelvic wedge during spinal anesthesia for cesarean section.
Aortocaval compression is a major cause of maternal hypotension. A randomized controlled trial was designed to determine the effectiveness of a mechanical intervention using a right lumbar-pelvic wedge in preventing hypotension after spinal anesthesia for cesarean delivery. ⋯ In our study population the use of right lumbar-pelvic wedge was not effective in reducing the incidence of hypotension during spinal anesthesia for cesarean section. Patients in whom the wedge was used had higher systolic blood pressure values during the first 5 min of anesthesia and fewer episodes of nausea. The risk of hypotension remains substantial.

Randomized Controlled TrialThe effect on maternal temperature of delaying initiation of the epidural component of combined spinal-epidural analgesia for labor: a pilot study.
Labor epidural analgesia is associated with maternal hyperthermia. This pilot study compared the effects on maternal temperature during labor of different timing of initiation of the epidural component of combined spinal-epidural analgesia. ⋯ Delaying the epidural component of combined spinal-epidural analgesia did not significantly affect maternal temperature in the study population of whom 83.3% had a labor of <5 h. However, this study was underpowered to detect a difference in the incidence of fever and a larger prospective study is required.
