On-Q System for Managing Trocar Site Pain after Operative Laparoscopy

Abstract The On-Q system provides long-term pain relief with continuous infusion of a local anesthetic directly into the trocar site after operative laparoscopy. An elastometric pump filled with bupivacaine HCl and a catheter, inserted by the surgeon, delivers 48 hours of anesthesia (100 ml) at a rate of 2 ml/hour. The pump is secured to the outer surgical dressing or to the patient's clothing with tape or an E clip provided in the package. The system can be removed by the patient when the infusion is complete.
