Resumen
MALO-MANSO, A. et al. Impact of opioid free anesthesia in bariatric surgery. Anales Sis San Navarra [online]. 2020, vol.43, n.1, pp.51-56. Epub 17-Ago-2020. ISSN 1137-6627. https://dx.doi.org/10.23938/assn.0757.
Background
Patients subjected to bariatric surgery present a greater risk of complications due to the use of opioids. The goal is to evaluate the security and suitability of the Opioid Free Anaesthesia (OFA) protocol implemented in the Hospital Universitario Virgen de la Victoria in 2018.
Method
Prospective study carried out on 38 patients subjected to laparoscopic bariatric surgery under the OFA protocol in the year 2018 at the H.U. Virgen de la Victoria (Málaga, Spain). Variables were gathered to establish haemodynamic control and perioperative pain, which were analysed using Stata v.16.
Results
The average age was 43 years; the average body mass index was 48.14 and the average stay in the operating theatre was 178 minutes. Control of hypertensive response following laryngoscopy occurred in 88.1% of the cases. On entering the Post Anaesthesia Care Unit (PACU), SpO2 without a supplementary contribution in the transfer showed a median of 97% with p75 ≥ 95%, while the p75 of pain evaluation by means of Visual Analogue Scale (VAS) was 3, with 68% of patients without pain. On discharge from the PACU, all presented VAS below 4 and it was only necessary to administer a low dose of Pethidine in seven patients.
Conclusion
The OFA has proved to be secure and achieves optimum pain control. In the reconverted cases, good control of the parameters opens up the possibility of its use in more painful surgeries.
