Randomized Controlled Trial
Effects of intrathecally administered fentanyl on duration of analgesia in patients undergoing spinal anaesthesia for elective caesarean section.
Intrathecal opioids have gained popularity in obstetrics; they augment the analgesia produced by local anaesthetic agents. The aim of this study is to determine the duration of analgesia following addition of fentanyl to bupivacaine during elective Caesarean section. ⋯ We conclude that the addition of 25 microg of fentanyl to bupivacaine intrathecally for elective Caesarean section increases the duration of complete and effective analgesia thereby reducing the need for early postoperative use of analgesics.
