Rapid Review Quiz: Postoperative Pain Management
Postoperative pain remains a significant concern for surgical patients, with implications that extend beyond immediate discomfort and influence recovery trajectories, patient satisfaction, and long-term outcomes. Effective pain control is not just a matter of comfort — it's a clinical imperative. Yet, this goal must be pursued judiciously, as the overreliance on opioids carries well-documented risks of adverse effects and dependence. The landscape of pain management is evolving. While pharmacologic strategies such as opioids, nonsteroidal anti-inflammatory drugs, n-methyl-d-aspartate (NMDA) receptor antagonists, and regional anesthesia continue to play pivotal roles, their limitations have catalyzed a shift toward a more integrative, multimodal approach. Emerging evidence supports the use of non-pharmacological interventions — ranging from preoperative patient education to mind-body techniques and physical therapy — as effective complements that can reduce pain intensity, curb opioid use, and enhance functional recovery.
Recent clinical guideline updates for managing postoperative pain emphasize increased use of non-opioid treatments and multimodal strategies. This reflects growing recognition that while opioids are effective, they pose risks such as dependence and adverse side effects. Nonpharmacological and non-opioid interventions such as nonsteroidal anti-inflammatory drugs, NMDA receptor antagonists like ketamine, peripheral nerve blocks, and techniques like transcutaneous electrical nerve stimulation have been shown to reduce opioid use, improve pain control, and enhance recovery outcomes, especially when healthcare professionals are adequately trained to apply them. Randomized controlled trials support the efficacy of peripheral nerve stimulation for postsurgical pain, and evidence for this and other novel therapies continues to grow. Even patient factors such as sleep quality and the timing of surgery can significantly impact post-operative pain.
Programmed intermittent epidural bolus injection was shown to be more effective than other methods in improving both nighttime pain management and sleep quality in post-thoracotomy patients. Oral opioid analgesics can manage pain, but they often cause side effects like nausea, sedation, and sleep disruption, which can worsen postoperative recovery. General anesthesia is used during surgery but has no role in managing postoperative pain or improving sleep afterward. It does not contribute to nighttime pain relief once the patient is in recovery.

For a patient requiring a minimal hospital stay and quick postoperative recovery, single-injection nerve blocks are often the preferred pain management strategy. These blocks provide effective, targeted pain relief with a rapid onset and are simple to administer, making them ideal for shorter or less complex surgical procedures. Their use has been associated with reduced opioid consumption, quicker mobilization, and high patient satisfaction — factors critical for fast recovery and early discharge. The major limitation to single-injection nerve blocks is the duration of analgesia, typically lasting less than 24 hours. Peripheral nerve blocks and neuraxial blocks are a few types of single-injection nerve blocks commonly used. Continuous catheter techniques are more invasive, require careful monitoring, and carry risks such as infection, catheter displacement, or pump malfunction. These factors can delay discharge and complicate recovery, making them less ideal for rapid recovery cases. Oral analgesics may not provide adequate pain control on their own, especially immediately after surgery. Insufficient pain management can hinder mobility and prolong hospital stay. Multiple-injection nerve blocks are not usually used, instead single-injection nerve blocks are recommended for quick postoperative recovery.

A primary benefit of continuous catheter techniques over single-injection nerve blocks for postoperative pain management is that they offer prolonged analgesia, which enhances patient comfort and reduces the need for additional analgesics. Unlike single-injection blocks that wear off within hours, continuous catheter methods — such as continuous peripheral nerve blocks or epidural analgesia — provide sustained pain relief for 2-3 days. This extended duration allows for better pain control, supports early mobilization, and lowers reliance on opioids, ultimately improving recovery outcomes and patient satisfaction. Catheter techniques actually require more monitoring due to risks like infection, catheter displacement, or pump malfunction. Continuous nerve catheters can be used in ambulatory surgery with the evolution of local anesthetic delivery systems and pumps and even in outpatient procedures. While effective, continuous catheter techniques may carry higher complication risks related to catheter management, such as infections or technical failures. Thus, their key advantage lies in providing extended, consistent pain control for patients with significant postoperative pain needs.

Nondrug pain management encompasses a range of physical, psychological, and sensory interventions that provide effective, low-risk alternatives to medications. Although effectiveness varies between individuals, TENS can provide pain relief, is noninvasive, and cost-effective. Heat therapy can also relieve muscle tension and pain and improve blood flow, but it can cause burns if used improperly. Cryotherapy can also reduce pain and inflammation, although it can sometimes impair healing and is not suitable for everyone. Cryotherapy can limit blood flow, reduce the delivery of healing agents to the affected area, and cause tissue necrosis or nerve impairment. Individual responses to aromatherapy vary widely, and clinical evidence supporting its effectiveness remains limited.
