Elastomeric Pain Pumps for Scoliosis Surgery

Area of Science:

• Orthopedic Surgery
• Pain Management
• Anesthesiology

Background:

• Postoperative pain control after scoliosis surgery traditionally relies on intravenous opioids.
• Opioid-based analgesia can lead to significant side effects, including prolonged hospital stays and gastrointestinal issues.

Purpose of the Study:

• To evaluate the efficacy of elastomeric pain pumps in managing postoperative pain following scoliosis surgery.
• To compare outcomes between patient-controlled analgesia, elastomeric pain pumps with bupivacaine, and multimodal pain pumps with gabapentin and methocarbamol.

Main Methods:

• Retrospective chart review of 81 adolescent patients undergoing scoliosis surgery.
• Patients were divided into three groups: patient-controlled analgesia (PCA), elastomeric pain pump, and multimodal pain pump.
• Analysis of length of hospital stay, infection rates, and postoperative gastrointestinal retention.

Main Results:

• The elastomeric pain pump group had a 3.1-day shorter hospital stay compared to the PCA group (P=0.004).
• The multimodal pain pump group experienced a 3.9-day shorter hospital stay than the PCA group (P=0.001).
• Incidence of prolonged postoperative bowel retention significantly decreased from 25% to 18% to 2% across the groups (P=0.03).

Conclusions:

• Elastomeric pain pumps, especially when combined with multimodal analgesia, offer significant improvements in postoperative recovery after scoliosis surgery.
• This approach is associated with reduced hospital length of stay and decreased incidence of gastrointestinal complications.
• The addition of gabapentin and methocarbamol to elastomeric pain pumps suggests a trend towards enhanced recovery.
