Opioid-free general anaesthesia for transthoracic oesophagectomy: does it improve postoperative analgesia and other recovery criteria? A prospective randomised study

Abstract

Background Side effects related to intraoperative opioid administration are well known. Recently, it was found that opioids may inhibit cellular immunity through their effects on natural killer cell activity, stimulate angiogenesis and accentuate cancer cell growth. Hence, peri-operative use of opioids might affect long-term oncological outcomes in cancer surgical patients. Opioid-free anaesthesia (OFA) is a methodology that dodges narcotic use during anaesthesia by using blends of several drugs added to common anaesthetic agents. The study aims to test the impact of OFA in transthoracic oesophagectomy in comparison with opioid-based anaesthesia technique (OBA) on postoperative analgesia and recovery criteria (hemodynamics, respiratory rate and haemoglobin oxygen saturation). Results The postoperative VAS was significantly lower in OFA group (A) than OBA group (B) in the measured time points (immediate postextubation, 30 min, 2 and 4 h postoperative) with P values 0.001, 0.001, 0.0012 and 0.0065 respectively. The time passed till first rescue analgesia requested was significantly longer in OFA group (A) than OBA group (B) and the total dose of rescue analgesia given to the patients were significantly higher in group B than group A. The recorded postoperative respiratory rate was significantly faster in OBA group (B) than OFA group (A), and the haemoglobin oxygen saturation (SPO2) showed statistically significant lower values in the OBA group (B) than the OFA group (A). Conclusions We emphasise the perioperative safety and efficacy of the opioid-free anaesthesia techniques provided for transthoracic oesophagectomy with better postoperative analgesia and other post recovery criteria. Trial registration We carried out our trial at Ain-Shams University Hospitals, Cairo, Egypt, between June 2020 and November 2020. The study was approved by the Research Ethics Committee at the Faculty of Medicine, Ain Shams University and then registered in the Pan African Clinical Trials Registry (https://pactr.samrc.ac.za/) with the following ID (PACTR202010907549506).

Opioid-Free Labor Analgesia: Dexmedetomidine as an Adjuvant Combined with Ropivacaine

“…Opioid-free anesthesia (OFA) is a multimode anesthesia strategy that combines multiple nonopioid drugs and/or techniques to obtain high-quality anesthesia and has recently gained increasing attention [ 4 ]. The impact of OFA has been investigated in the case of transthoracic oesophagectomy in comparison with opioid-based anesthesia technique (OBA) on postoperative analgesia and recovery criteria (hemodynamics, respiratory rate, and hemoglobin oxygen saturation) [ 5 ].…”

Ketodex versus opioid based anesthesia in cleft palate

“…A study done by Abdelrahman and Algharabawy. 17 showed that there were statistically significant lower values in opioid based anesthesia group than opioid free anesthesia at 20 min, 30 min post extubation and at the first and second hours postoperatively. But this difference was insignificant immediately and after 10 min post extubation, third, Our study showed that the incidence of vomiting was higher in the Group OP with significant difference than the Group KD.…”
