Does Pregabalin Improve Post-operative Pain After C-section Delivery

Overview

Pregabalin due to its antihyperalgesic effect, has proven its efficacy on neuropathic pain, essentially in nociceptive surgeries. Few studies have attempted to identify the utility of pregabalin as a premedication before cesarean delivery. The investigators aimed to determine whether or not pregabalin as premedication improves analgesia post cesarean delivery.

The investigators conducted a controlled, randomised, prospective and double-blind trial. One hundred thirty eight participants were included, with American Society of Anesthesiologists physical status classification of I to II, with pregnancies of at least 36 weeks of gestation who were scheduled for elective caesarean delivery under spinal anaesthesia. One hour before induction of anaesthesia participants received a capsule containing sugar placebo (placebo group), pregabalin 150 mg or pregabalin 300 mg. Data related to surgical history, pre-existing medical problems, indications for cesarean and peroperative hemodynamic changes were analyzed. The primary outcome was first analgesic request. Secondary outcomes included maternal pain scores at rest and during movement, rescue analgesics consumption, sedation, nausea, vomiting, pruritus and Apgar scores. All maternal secondary outcome variables were recorded 0, 2, 4, 6, 12, 18, and 24 h after delivery. Common side effects linked to pregabalin such as somnolence, blurred or abnormal vision, or fetal distress were collected.
