Opioid-Sparing Anesthesia: Gabapentin and Postoperative Pain

Area of Science:

• Anesthesiology and Pain Management
• Pharmacology

Background:

• Nonopioid analgesics are crucial for perioperative pain management, often augmenting or replacing opioids.
• Gabapentin, an anticonvulsant, demonstrates analgesic properties and can mitigate postoperative nausea and vomiting.
• Perianesthesia nurses require guidance on optimal timing and administration of gabapentin, especially with concurrent sedative medications.

Approach:

• A systematic review was conducted, searching CINAHL, PubMed, and Cochrane Review databases.
• Ninety-three sources were initially identified, with four randomized controlled trials (RCTs) meeting inclusion criteria.
• The primary outcome measured was postoperative pain within 24 hours of surgery using the visual analog scale.

Key Points:

• Three of the four RCTs found gabapentin significantly reduced postoperative pain, both statistically and clinically.
• All four studies indicated a reduction in opioid consumption in the immediate postoperative period.
• Reduced opioid use correlated with improved patient satisfaction.

Conclusions:

• Gabapentin shows promise in managing postoperative pain and decreasing opioid reliance.
• Further investigation with robust methodology and diverse participant selection is warranted.
• Enhanced understanding can optimize gabapentin's role in multimodal perioperative analgesia.
