Across the USA and various parts of the world, ambulatory surgery centers have transitioned to accepting patients with advanced ASA statuses, leading to a larger volume and higher complexity of surgeries performed, while still urging for same-day patient discharges. Inadequate postoperative pain management and opioid analgesia side effects, such as sedation, respiratory depression, and postoperative nausea and vomiting, are the most common complications and most common reasons for readmission after ambulatory surgery. The trend to limiting these complications and achieve a more rapid patient discharge currently emphasizes a multifactorial, balanced analgesia strategy. This article reviews the multimodal approach by detailing the important aspects of specific regional nerve blocks, nerve blockade with catheter techniques, acetaminophen, non-selective NSAIDs, Cox-2 inhibitors, membrane stabilizers, and corticosteroids. Pain management in the ambulatory surgery patient will thus be optimized with a thorough preoperative evaluation, recognizing intraoperative events, and implementing multiple analgesic modalities.
