Opioid-free Vs Traditional Balanced Anesthesia in Laparoscopic Colorrectal Surgery

Overview

The goal of this clinical trial is to compare opioid free anesthesia versus opioid anestheisa in patients undergo laparoscopic colorrectal surgery. The main question it aims to answer is assess the efficacy of opioid-free anaesthesia respect to postoperative pain control in patients undergoing a laparoscopic colorectal surgery. Participants will answer a questionnaire during the first 3 days of admission, assessing pain through the visual analog scale (VAS). The researchers will compare the consumption of opiates during the postoperative period in the opioid-free anesthesia group.

Detailed Description

The objective of the study is to know the efficacy of OFA in laparoscopic colorectal surgery. The consumption of opiates will be evaluated according to the VAS scale, defining non-tolerable pain greater than 5. The number of rescues required, the time elapsed until the first rescue and the total consumption of opiates administered will be evaluated. Other variables that will be evaluated will be safety variables defined as intraoperative complications that require immediate action by the anesthesiologist, interruption of the procedure, or conversion to open surgery. Other variables evaluated will be postoperative complications: – Postoperative hypoxemia. – Incidence of postoperative nausea and vomiting (PONV). – Postoperative ileus. – surgical complications. – medical complications

Interventions

  • Drug: Opioid free anesthesia
    • Administer a combination of drugs in substitution for morphine

Arms, Groups and Cohorts

  • Experimental: Opioid free anesthesia (OFA)
    • This arm is composed of opiate-free anesthesia, for this we will use Dexmetomidine dexdor), lidocaine, magnesium sulfate, ketamine (ketolar), Dexketoprofen (Enantyum) , dexamethasone and acethominophen.
  • Active Comparator: Opioid based Anesthesia (OA)
    • This arm of opiate-based anesthesia is composed of Remifentanil hidrochloride. Postoperative rescue analgesia will be morphine along with dexketoprofen, acethominophen, and dexamethasone.

Clinical Trial Outcome Measures

Primary Measures

  • Pain control
    • Time Frame: 3 days
    • milligrams of opioids required postoperatively during the first 3 of admission

Secondary Measures

  • VNS score
    • Time Frame: 3 days
    • Pain measured through the visual analogue scale (VAS) during the first 3 days of admission
  • morphine rescues
    • Time Frame: 7 days
    • Number of opiate rescues required during the postoperative period
