Perioperative Acetaminophen and Dexmedetomidine Eliminate Post-Operative Opioid Requirement following Pediatric...

Administration of post-operative opioids following pediatric tonsillectomy can elicit respiratory events in this patient population that often arise as central and obstructive sleep apnea. The primary objective of this study was to determine whether a perioperative combination of dexmedetomidine and acetaminophen could eliminate post-operative (in recovery and at home) opioid requirements. Following IRB approval and a waiver for informed consent, the medical records of 681 patients who underwent tonsillectomy between 1 January 2013 and 31 December 2018 were evaluated. Between 1 January 2013 and 31 December 2015, all patients received a fentanyl-sevoflurane-based anesthetic, without acetaminophen or dexmedetomidine, and received opioids in recovery and for discharge home. On 1 January 2016, an institution-wide practice change replaced this protocol with a multimodal perioperative regimen of acetaminophen (intravenous or enteral) and dexmedetomidine and eliminated post-operative opioids. This is the first time that the effect of an acetaminophen and dexmedetomidine combination on the perioperative and home opioid requirement has been reported. Primarily, we compared the need for rescue opioids in the post-anesthesia care period and after discharge. The multi-modal protocol eliminated the need for post-tonsillectomy opioid administration. Dexmedetomidine in combination with acetaminophen eliminated the need for post-operative opioids in the recovery period.
