Effect of Multimodal Opioid-free Anesthesia on Return of Bowel Function in Laparoscopic Colorectal Surgery

Brief Summary

The objective of this study is to determine if an opioid-free general anesthetic (OFA) technique utilizing lidocaine, ketamine, dexmedetomidine and magnesium reduce postoperative opioid consumption and speed return of bowel function in patients undergoing elective, laparoscopic, colorectal surgery compared to traditional opioid-containing general anesthetic techniques. It is hypothesized that this intraoperative OFA regimen will reduce postoperative opioid consumption, and expedite return of bowel function in this population.

    Primary Outcomes
    • Time between the end of surgery and the movement when the patient first passes flatus

    Secondary Outcomes
    • Time between the end of surgery and the moment the patient first passes stool

    • Time between the end of surgery to when the patient can tolerate any oral solid food intake

    • Total amount of opioid (morphine equivalents) required in PACU

    • Total amount of PCA morphine (mg) required from end of surgery to 48 hours postoperatively

    • Time to Post-Anesthetic Care Unit (PACU) discharge readiness

    • Visual Analogue Scale (VAS) pain scores will be recorded on a scale of 0 to 10, with 0 indicating no pain, and 10 indicating extreme pain, 48 hours following surgery

    • Assessed using the Quality of Recovery (QoR) 15 questionnaire, a validated tool for measuring quality of recovery after anesthesia and surgery
