It has been demonstrated that female patients have poor quality of surgical recovery compared to male patients. Increased sensitivity to pain and increased susceptibility to postoperative nausea and vomiting have been attributed as causal factors. Currently, few strategies have been shown to improve quality of recovery in female patients undergoing laparoscopic hysterectomy. A better recovery in female patients undergoing outpatient laparoscopy is particularly desirable since those patients do not have access to potent intravenous medications and nursing support after hospital discharge.
Our group has previously demonstrated that both TAP block and systemic lidocaine improve quality of recovery after outpatient laparoscopic gynecological surgery. The TAP block, however, requires expertise, equipment (ultrasound), and additional time to perform as compared with a simple lidocaine infusion. It is currently unknown if a systemic lidocaine infusion provides non-inferior quality of recovery when compared to TAP block for outpatient laparoscopic gynecological surgery.
The main objective of the current investigation is to examine the effect of TAP block on quality of recovery compared to a systemic lidocaine infusion. We hypothesize that systemic lidocaine infusion would provide non-inferior quality of recovery when compared to TAP block for outpatient laparoscopic gynecological surgery.
Significance: This is the first study to compare systemic lidocaine to TAP block with regard to quality of recovery.
The research question; does systemic lidocaine provide similar quality of recovery as TAP block for outpatient laparoscopy? The hypothesis; systemic lidocaine provides non-inferior quality of recovery as TAP block for outpatient laparoscopy.
Research significance: It has been shown that females have poor surgical recovery compared to males; this project intends to demonstrate that systemic lidocaine provides similar recovery as TAP blocks but it does not require the expertise, equipment, and time needed to perform TAP blocks.
