Efficacy And Safety of Wound Infiltration Modalities For Postoperative Pain Management After Cesarean Section: A Systematic Review, Meta-Analysis, And Trial Sequential Analysis Protocol
Abstract Background: Inadequately managed postoperative pain after cesarean section has a number of consequences to the mother in the postoperative period. Different postoperative pain management modalities have been practiced after cesarean section over the years. The opioid based analgesics and land mark techniques have undesirable consequences, regional analgesia technique with ultrasound requires resource and expertise while different wound infiltration techniques are new techniques with minimal side effect and easy to administer. However, the effectiveness of each technique is uncertain and needs further investigation.Objective: This systematic review will provide the most effective wound infiltration technique to prevent undesirable adverse effects of opioids and untreated painMethod: A comprehensive search will be conducted in PubMed/Medline, Cochrane, Science direct, CINHAL, and LILACS without date and language restriction. All randomized trials comparing the efficacy of wound infiltration for postoperative pain management after cesarean section will be included. The data will be extracted with two independent authors in a customized format. The methodological quality of included studies will be evaluated using the Cochrane risk of bias tool. The overall quality of the evidence will be determined by GRADEpro software. Trial Sequential Analysis will be conducted to investigate the necessity of further trials.Discussion: The incidence of postoperative acute as well as chronic pain is very high which has a tremendous impact on the mother, family, healthcare providers, and healthcare delivery. It is a basic human right to provide postoperative pain management to every patient that is feasible to everyone in terms of resources, technique, cost, and minimal adverse events profileRegistration: This systematic review protocol was registered in Prospero (CRD42021270710) on September 5, 2021
