New Guidelines Released for Postoperative Pain Management

News Author: Pauline Anderson
CME Author: Laurie Barclay, MD

Acute postoperative pain is common, occurring in more than 80% of patients, with approximately 75% of these having moderate, severe, or extreme pain. Postoperative pain relief is inadequate in more than half of patients, which can negatively affect quality of life, function, and functional recovery, as well as increasing the risks for postsurgical complications and persistent postsurgical pain.

The American Pain Society (APS), in collaboration with the American Society of Anesthesiologists, commissioned an evidence-based guideline on postoperative pain management to promote effective and safer postoperative pain management in children and adults. Topics include preoperative education, perioperative pain management planning, use of different pharmacologic and nonpharmacologic modalities, organizational policies and procedures, and transition to outpatient care.

The APS has released a new evidence-based clinical practice guideline that includes 32 recommendations related to postoperative pain management in children and adults.

The guideline is based on the findings of an interdisciplinary expert panel. The APS commissioned the panel with input from the American Society of Anesthesiologists, and the document was subsequently approved by the American Society of Regional Anesthesia and Pain Management.

Research shows that most surgical patients receive inadequate pain relief, which can increase the risks for prolonged postoperative pain, mood disorders, and physical impairment, said lead author Roger Chou, MD, Departments of Medicine and Medical Informatics and Clinical Epidemiology, Oregon Health and Science University, Pacific Northwest Evidence Based Practice Center, Portland.

A key recommendation in the guideline, published in the February issue of the Journal of Pain, is wider use of multimodal techniques, Dr Chou told Medscape Medical News.

“This means using different medications, for example opioids and nonopioid therapies such as non-steroidal anti-inflammatories (NSAIDs), gabapentin/pregabalin, ketamine, lidocaine, administered in different ways, for example, systemically or via neuraxial/peripheral regional anesthetic techniques, as well as medications and nonpharmacological therapies.”

Multimodal strategies help achieve better pain relief while using lower doses of opioids and potentially fewer adverse effects, by affecting pain via different mechanisms of actions and pathways, added Dr Chou.

The recommendation on individualizing therapy is also critical, said Dr Chou. “The same strategy is not going to be ideal in all patients. For example, in patients who are already on long-term opioid therapy prior to surgery, managing their pain is not going to be the same as someone not on opioids.”

The guideline was developed by a 23-member expert panel representing anesthesia, pain management, surgery, nursing, and other medical specialties. It is based on the panel’s review of more than 6500 scientific abstracts and primary studies.

The panel rated each recommendation as strong, moderate, or weak and based each on the quality of the scientific evidence. Of the 32 recommendations, the panel rated only 4 as supported by high-quality evidence, and 11 recommendations were based on low-quality evidence. The guideline authors noted that there were “numerous research gaps.”

In addition to using multimodal therapies, the 3 other strong recommendations with high-quality evidence included the following:

• Using acetaminophen and/or NSAIDs as part of multimodal analgesia for management of postoperative pain in adults and children without contraindications;

• Considering surgical site-specific peripheral regional anesthetic techniques in adults and children for procedures with evidence indicating efficacy; and

• Offering neuraxial analgesia for major thoracic and abdominal procedures, particularly in patients at risk for cardiac complications or prolonged ileus.

Strong recommendations with moderate-quality evidence included the following:

• Administering oral vs intravenous (IV) opioids in patients who can use the oral route;

• Avoiding the intramuscular route for administration of analgesic;

• Choosing IV patient-controlled analgesia (PCA) when the parenteral route is needed;

• Not using routine basal infusion of opioids with IV PCA in opioid-naive adults;

• Considering a preoperative dose of oral celecoxib in adults without contraindications;

• Considering gabapentin or pregabalin as a component of multimodal analgesia;

• Using topical local analgesics in combination with nerve blocks before circumcision;

• Avoiding intrapleural analgesia with local anesthetics for pain control after thoracic surgery;

• Using continuous, local anesthetic-based peripheral regional analgesic techniques when the need for analgesia is likely to exceed the duration of effect of a single injection; and

• Avoiding the neuraxial administration of magnesium, benzodiazepines, neostigmine, tramadol, and ketamine.

Despite low-quality evidence, the panel strongly recommended that clinicians carry out the following strategies:

• Provide patients with education, including information on treatment options;

• Conduct a preoperative evaluation, including assessment of medical and psychiatric comorbidities, concomitant medications, history of chronic pain, and substance abuse;

• Adjust the pain management plan on the basis of adequacy of pain relief and presence of adverse events;

• Use a validated pain assessment tool to track response to postoperative pain treatments and adjust treatment plans accordingly;

• Appropriately monitor sedation, respiratory status, and other adverse events in patients who receive systemic opioids; and

• Provide appropriate monitoring of patients who have received neuraxial interventions for perioperative analgesia.

For cognitive behavioral therapy, the panel had a “weak” recommendation based on moderate-quality evidence to consider this technique as part of a multimodal approach.

The panel found that there was insufficient evidence to recommend or discourage acupuncture, massage, or cold therapy as adjuncts to other postoperative pain treatments. For transcutaneous electrical nerve stimulation, the panel had a “weak” recommendation that clinicians consider this treatment.

As evidence increases on newer techniques for managing postoperative pain, it is important to incorporate these techniques into current practice to improve management of postoperative pain, said Dr Chou. He noted that the APS has not previously issued guidelines on management of postoperative pain and recognizes that this as an important area where evidence-based guidelines could help improve clinical practice.

Dr Chou has disclosed no relevant financial relationships.

• Currently many preoperative, intraoperative, and postoperative interventions and management strategies are available to reduce and manage postoperative pain.

• Optimal management begins preoperatively with patient evaluation and development of a plan of care specific to each patient and procedure.

• Evidence supports multimodal treatment in many situations, using a variety of analgesic medications and techniques combined with nonpharmacologic interventions, for their synergistic effects and more effective pain relief (strong recommendation; high-quality evidence).

• In multimodal treatment, appropriate monitoring is needed to identify and manage adverse events because of the different adverse effect profile for each analgesic medication or technique used.

• Specific components of effective multimodal care should be tailored to the patient, setting, and surgical procedure (strong recommendation; low-quality evidence).

• Multimodal treatment should include use of around-the-clock acetaminophen and/or NSAIDs for adults and children without contraindications (strong recommendation; high-quality evidence).

• For certain surgical sites, specific peripheral regional anesthetic techniques are effective and should be used in adults and children when appropriate (strong recommendation; high-quality evidence).

• For major thoracic and abdominal surgeries, neuraxial analgesia should be considered, especially in patients at risk for cardiac complications or prolonged ileus (strong recommendation; high-quality evidence).

• Other strong recommendations are supported by moderate-quality evidence.

• Oral opioids are preferred to IV opioids in patients who can tolerate oral administration, because the efficacy of IV is not superior to oral. Because postoperative pain is often continuous initially, it often requires around-the-clock dosing during the first 24 hours. Long-acting oral opioids are generally not recommended in the immediate postoperative period.

• Analgesics should not be administered intramuscularly because intramuscular administration can cause significant pain, absorption is unreliable, and it has no clearly shown advantages vs other routes of administration.
Patients requiring parenteral analgesia should be given IV PCA.

• Opioid-naive adults should not receive routine basal opioid infusion using IV PCA.

• Adults without contraindications may benefit from a preoperative dose of oral celecoxib.

• Gabapentin or pregabalin may be a suitable intervention in multimodal analgesia.

• Topical local analgesics combined with nerve blocks may be useful before circumcision.

• Intrapleural analgesia with local anesthetics is not recommended for pain control after thoracic surgery.

• When the need for analgesia is likely to be longer than a single injection can provide, continuous, local anesthetic-based peripheral regional analgesic techniques are recommended.

• Neuraxial administration of magnesium, benzodiazepines, neostigmine, tramadol, and ketamine is not recommended.
Numerous research gaps still exist, as indicated in the systematic review underlying these guidelines.

• Only 4 of 32 recommendations were supported by high-quality evidence, and 11 (regarding patient education, perioperative planning, patient evaluation, organizational structures and policies, and transitioning to outpatient care) were based on low-quality evidence.

• The APS has issued guidelines for postoperative pain management, recommending multimodal regimens tailored to the specific patient and procedure.

• Other strong recommendations for postoperative pain management were supported by moderate-quality evidence, including preference for oral to IV opioids when feasible and avoidance of intramuscular administration.

• Implications for the Healthcare Team: Members of the healthcare team should be aware that numerous research gaps still exist, and only 4 of 32 recommendations were supported by high-quality evidence.
