Randomized Controlled TrialThe effect of intravenous ondansetron on maternal haemodynamics during elective caesarean delivery under spinal anaesthesia: a double-blind, randomised, placebo-controlled trial.
Spinal anaesthesia for caesarean delivery is frequently associated with adverse effects such as maternal hypotension and bradycardia. Prophylactic administration of ondansetron has been reported to provide a protective effect. We studied the effect of different doses of ondansetron in obstetric patients. ⋯ In our study, prophylactic ondansetron had little effect on the incidence of hypotension in healthy parturients undergoing spinal anaesthesia with bupivacaine and fentanyl for elective caesarean delivery.

Randomized Controlled Trial Comparative StudyA randomized comparison of onset of anesthesia between spinal bupivacaine 5mg with immediate epidural 2% lidocaine 5mL and bupivacaine 10mg for cesarean delivery.
Previous studies using low-dose spinal anesthesia for cesarean delivery have focused on hypotension and efficacy. This study evaluated whether, using a combined spinal-epidural technique, there was a difference in onset of anesthesia for cesarean delivery between low-dose spinal with an immediate epidural local anesthetic bolus, and conventional-dose spinal anesthesia. ⋯ Intrathecal bupivacaine 5 mg with immediate 2% epidural lidocaine 5 mL provided comparable onset and efficacy of anesthesia as bupivacaine 10 mg with immediate epidural normal saline 5 mL for cesarean delivery.

Randomized Controlled Trial Comparative StudyRemifentanil versus placebo for analgesia during external cephalic version: a randomised clinical trial.
Breech presentation occurs in up to 3% of pregnancies at term and may be an indication for caesarean delivery. External cephalic version can be effective in repositioning the fetus in a cephalic presentation, but may be painful for the mother. Our aim was to assess the efficacy of remifentanil versus placebo for pain relief during external cephalic version. ⋯ Intravenous remifentanil with bolus doses on demand during external cephalic version achieved a reduction in pain and increased maternal satisfaction. There were no additional adverse effects, and no difference in the success rate of external cephalic version or the incidence of fetal bradycardia.

Randomized Controlled TrialAnalgesic effects of intrathecal tramadol in patients undergoing caesarean section: a randomised, double-blind study.
Intrathecal tramadol combined with local anaesthetics has been used for postoperative analgesia following lower abdominal and perineal surgery. The present study evaluated the effect of intrathecal tramadol on spinal block characteristics and neonatal outcome after elective caesarean section. ⋯ Compared to intrathecal fentanyl 10 μg, tramadol 10 mg, as an adjunct to bupivacaine for subarachnoid block for caesarean section, showed a longer duration of analgesia with a reduced incidence of shivering.

Randomized Controlled TrialEfficacy of ultrasound-guided transversus abdominis plane blocks for post-cesarean delivery analgesia: a double-blind, dose-comparison, placebo-controlled randomized trial.
TAP blocks may offer some small analgesic benefit after caesarean section at 6h and 12h, but not 24h, in patients also receiving intrathecal morphine.
