Pharmacological Postoperative Pain Management for Paediatric Dental Extractions Under General Anaesthesia: A Systematic Review.

General anaesthesia (GA) as a pharmacological behaviour management strategy may be indicated for dental extractions in children unable to cooperate in the dental chair. Pain is the most common postoperative complication in children following dental GA. There is conflicting evidence available on the efficacy of local anaesthetic (LA) agents for postoperative pain management following dental extraction. Therefore, this review aimed to evaluate the efficacy of different pharmacological analgesic techniques on postoperative pain following dental extractions under GA in children. A search of PubMed, Embase, Scopus and CINAHL was conducted on 17/10/2023 to identify studies eligible for inclusion in this review. Two independent reviewers performed search screening, data extraction and critical appraisal. Results were narratively described due to heterogeneity of pain assessment tools and management strategies. The search yielded 8742 results, of which 15 studies were included. Methods of pain assessment varied greatly across included studies, with 14 different pain scales used across the 15 studies. Included studies suggest preoperative oral paracetamol and oral ibuprofen as well as postoperative topical bupivacaine lowered pain scores. This review underscores the challenges in reliably assessing pain in children and highlights the necessity for age-specific validated pain assessment tools.
