Combined spinal-epidural vs. dural puncture epidural techniques for labour analgesia: a randomised controlled trial.

Background: The dural puncture epidural technique is a modification of the combined spinal-epidural technique. Data comparing the two techniques are limited. We performed this randomised study to compare the quality of labour analgesia following initiation of analgesia with the dural puncture epidural vs.

The 90% effective dose of intrathecal hyperbaric bupivacaine for Cesarean delivery under combined spinal-epidural anesthesia in parturients with super obesity: an up-down sequential allocation study.

Purpose: To determine the 90% effective dose (ED) of intrathecal hyperbaric bupivacaine for Cesarean delivery under combined spinal-epidural anesthesia (CSE) in parturients with super obesity (body mass index [BMI] ≥ 50 kg·m).

Methods: We enrolled parturients with BMI ≥ 50 kg·m with term, singleton vertex pregnancies undergoing elective Cesarean delivery under CSE. An independent statistician generated the 0.
