NCT ID: NCT06404983 Recruiting - Breast Cancer Clinical Trials

Opioid-free Anaesthesia in Breast Cancer Surgery

Start date: December 28, 2022
Phase: N/A
Study type: Interventional

Background: Various analgesic modalities are adopted for perioperative analgesia in breast cancer surgeries. Opioid-free and opioid-sparing techniques are gaining popularity due to the lack of opioid-dependent undesirable effects, including respiratory depression, urinary retention, nausea and vomiting, constipation, itching, opioid-induced hyperalgesia, tolerance, addiction, and immune system disorders. The goal of this prospective randomized clinical trial is to investigate the impact of opioid-free anaesthesia (OFA) versus conventional general anaesthesia (CGA) on postoperative analgesic requirements after breast cancer surgery (lumpectomy/mastectomy, with or without axillary lymph node excision). Secondary objectives include comparative perioperative evaluation of cognitive function and postoperative adverse events during the first 48 hours atfter surgery. Comparative evaluation of intraoperative haemodynamics and hospital length of stay are also secondary objectives, as well as the incidence of neuropathic pain assessed by validated questionnaires at 3 and 6 months postoperatively. During the preoperative screening, body measurements, age, gender, ASA (American Society of Anesthesiologists) physical status classification, educational level (using a 6-level scale: elementary, middle school, high school, higher education, higher education, and postgraduate/doctoral degree), home medication, and comorbidities (using the Charlson Comorbidity Index) are recorded. Intraoperatively, the duration of anaesthesia, duration of surgery, associated intraoperative data (e.g., haemodynamic instability, adverse effects associated with protocol-administered pharmaceutical agents, etc.), and medications administered (type and quantity) are recorded. The investigators expect to recruit at least 100 participants per group.

LIdocaine veRsus Sufentanil Anaesthesia in Cardiac Surgery With Cardiopulmonary Bypass

LISRACC
Start date: December 1, 2021
Phase:
Study type: Observational

Since the 90's the concept of morphine sparing and morphine free anaesthesia (OFA) has progressively developed in non-cardiac surgery. The principle is based on the fact that in a sleeping patient a sympathetic reaction marked by hemodynamic modifications does not translate into a painful phenomenon, that a painful phenomenon in a sleeping patient is not memorized, that hormonal stress, the sympathetic reaction and the inflammatory reaction can be controlled by other therapeutic classes than a morphine agent. This therapeutic management would avoid the side effects associated with the use of morphine. In this hypothesis, OFA is more and more practiced in various situations without the real impact in terms of clinical benefit being clearly demonstrated. In cardiac surgery, some centers practice OFA with various protocols.The purpose of this work is to retrospectively evaluate over a defined period the incidence of postoperative complications, length of stay in the ICU/hospital, and death rate between patients managed with/without OFA based on lidocaine.

NCT ID: NCT04854577 Not yet recruiting - Clinical trials for Opioid Free Anaesthesia

Postoperative Opioid-Sparing Effect of a Pecto-Intercostal Fascial Block and Opioid-Free Anesthesia.

Start date: May 2021
Phase: N/A
Study type: Interventional

The present study aims to assess the difference in postoperative opioid consumption between patients who intraoperatively receive a pecto-intercostal facial block combined with opioid-free anesthesia versus a traditional opioid-based regimen for cardiac surgery. The literature on opioid-free anesthesia for cardiac surgery is minimal and solely consists of case reports and retrospective studies. Nevertheless, these reports show the feasibility of opioid-free anesthesia. The purpose of this study is to assess the opioid-sparing effect and efficacy of combining an opioid-free anesthetic regimen with a pecto-intercostal fascial plane block (PIFB) in patients undergoing cardiac surgery. We hypothesize that opioid-free cardiac anesthesia with an intraoperative PIFB significantly reduces postoperative opioid consumption in comparison to a high-dose opioid intraoperative regimen.

Opioid Free Anaesthesia in Cardiac Surgery With Cardiopulmonary Bypass

OFACAR 1
Start date: January 1, 2019
Phase:
Study type: Observational

Since the 1990s, the concept of anesthesia without morphine (OFA) has been developed. The principle is based on the fact that in a sleeping patient a sympathetic reaction marked by hemodynamic changes does not reflect a painful phenomenon, that a painful phenomenon in a sleeping patient is not memorized, that hormonal stress, sympathetic reaction and inflammatory reaction can be controlled by therapeutic classes other than a morphine agent. This therapeutic management would avoid the side effects associated with the use of morphine. In cardiac surgery, no studies have evaluated the effect of an OFA on morphine consumption and on a post-operative composite endpoint. Lidocaine was only studied in the context of cardioprotection and neuroprotection. Studies found a cardioprotective effect with a decrease in episodes of rhythmic disorders, and neuroprotective with a non-constant improvement in postoperative cognitive functions, but all these studies were performed during opioid anaesthesia (opioid agent use)/ The purpose of our study is to demonstrate that general anesthesia without opioid (OFA) is associated with a decrease in post-operative morphine consumption and an improvement in the patient's post-operative well-being (complications, confusion, vigilance, length of stay).

NCT ID: NCT03120234 Completed - Clinical trials for Opioid Free Anaesthesia

Comparison of Opioid Based and Opioid Free Anaesthesia in Transsphenoidal Surgery

Start date: January 2017
Phase: N/A
Study type: Interventional

This study has been planned to compare the effect of opioid free anaesthesia using dexmedetomidine and ketamine with opioid based anaesthesia using fentanyl in maintaining the intraoperative hemodynamic stability and recovery characteristics in patients undergoing Transsphenoidal surgery of pituitary tumors.

NCT ID: NCT02150161 Terminated - Clinical trials for Postoperative Analgesia

Opioid vs. Opioid-free Anesthesia for Hip Arthroscopy

Start date: May 2014
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether an infusion of lidocaine/ketamine compared to fentanyl is equivalent in anesthesia effectiveness and can help reduce the incidence of postoperative nausea and vomiting in patients undergoing elective hip arthroscopy surgery.
