Bupivacaine Wound Instillation via an Electronic Patient-Controlled Analgesia Device and a Double-Catheter System Does Not Decrease Postoperative Pain or Opioid Requirements After Major Abdominal Surgery

Abstract

After major abdominal surgery performed through a 20-cm incision, repeated 0.25% bupivacaine wound instillation via an electronic patient-controlled analgesia device and a double-catheter system does not decrease postoperative pain or opioid requirements.
