Clinical Trial Summary

The objective of this study is to determine the effect of preoperative duloxetine on postoperative quality of recovery after ambulatory surgery, specifically laparoscopic gynecological surgery.


Description:

It has been demonstrated that female patients have poor quality of surgical recovery compared to male patients.1 Increased sensitivity to pain and increased susceptibility to postoperative nausea and vomiting have been attributed as causal factors.2, 3 Currently, few strategies have been shown to improve quality of recovery in female patients undergoing laparoscopic hysterectomy.4 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.

In addition, pain after ambulatory surgery remains an unsolved problem in The United States and Europe.5,6 It is associated with delayed hospital discharge and it can result to an increased opioid consumption with adverse side effects. The concept of multimodal analgesic technique was introduced more than 15 years ago and several techniques have been studied over the years including NSAIDs, acetaminophen, membrane stabilizers, ketamine, and local and regional anesthetic techniques.7,8 Both serotonin and norepinephrine have involvement in modulation of pain mechanisms in the central nervous system. Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor that has been used for mitigation of pain in such conditions as chronic musculoskeletal pain, diabetic peripheral neuropathic pain, post-herpetic neuralgia, and fibromyalgia.9,10 Duloxetine was also found to reduce postoperative morphine requirements in patients undergoing knee replacement surgery.11 The MQOR 40 is a validated instrument that was specifically design to evaluate patient recovery after anesthesia and surgery.12 This instrument can be particularly valid to examine interventions which affect different spheres of patient recovery as is the case of duloxetine.

A suicidal behavior questionnaire (SBQ-R) will be used to screen for suicidal risk among potential subjects. If any subject exhibits suicidal ideation as a result of scoring high on the questionnaire, there surgeon and/or primary care provider will be notified by the principal investigator.

The objective of this study is to determine the effect of preoperative duloxetine on postoperative quality of recovery after ambulatory surgery.

Significance: Use of preoperative duloxetine may improve patient's quality of recovery, decrease postoperative pain, opioid consumption and opioid related side effects after ambulatory surgery.
