It was not previously known to be useful in acute perioperative conditions, but recently it has been used for acute perioperative conditions. However, evidence-based medicine suggests that perioperative administration is useful for postoperative analgesia, preoperative anxiolysis, attenuation of the hemodynamic response to laryngoscopy and intubation, and preventing chronic postsurgical pain, postoperative nausea and vomiting (PONV), and delirium. This article reviews the clinical trial data to describe the efficacy and safety of gabapentin for perioperative anesthetic management. Aim The aim of the study was to evaluate and update the effect of preoperative gabapentin on the incidence of postoperative vomiting and on analgesic requirements after adenotonsillectomy in pediatrics. Materials and methods This randomized, double-blind study was designed to explore the possible effects of oral gabapentin as a premedication on the incidence and severity of PONV and on the early recovery profile of pediatric patients undergoing adenotonsillectomy under sevoflurane anesthesia. Results The incidence of PONV in the gabapentin group was significantly lower than in the gabapentin group. However, the numbers of rescue ondansetron doses and the PONV severity score were comparable in the two groups. Conclusion The use of gabapentin as premedication in pediatric patients undergoing adenotonsillectomies under sevoflurane anesthesia reduces the incidence of PONV and emergence agitation in the early postoperative period. However, gabapentin did not reduce pain and analgesic consumption after surgery.
