Perioperative Hypothermia: Mechanism, Risk Factors and New Protocols in Prevention and Treatment

Öz

ABSTRACT Introduction: Perioperative hypothermia (POH) is defined as a core temperature drop below 36°C during anaesthesia and surgery and leads to coagulation disorders, increased transfusion requirements, delayed wound healing and an elevated infection risk, prolonged hospitalisation and increased costs. It is therefore vital to maintain normal body temperature both before and after surgery in order to ensure optimal surgical outcomes, as well as patient safety and satisfaction. Methods: In order to ensure optimal outcomes, it is imperative that prevention and management of POH should include preoperative risk assessments, monitoring of perioperative body temperature, control of environmental temperature, and the development of comprehensive warming protocols and checklists. Conclusion: The present review examines recent studies and technological advancements regarding risk factors and prevention strategies for POH, with the aim of providing a practical guide for clinicians. Keywords: Perioperative hypothermia, general anaesthesia, neuroaxial blocks, normothermia

ÖZET Giriş: Perioperatif hipotermi (POH), anestezi ve ameliyat sırasında vücut çekirdek sıcaklığının 36°C'nin altına düşmesi olarak tanımlanır ve pıhtılaşma bozukluklarına, artan transfüzyon ihtiyacına, yara iyileşmesinin gecikmesine ve enfeksiyon riskinin artmasına, hastanede kalış süresinin uzamasına ve maliyetlerin artmasına yol açar. Bu nedenle, optimal cerrahi sonuçların yanı sıra hasta güvenliği ve memnuniyetini sağlamak için hem ameliyat öncesi hem de sonrasında normal vücut sıcaklığının korunması hayati önem taşır. Yöntem: Optimal sonuçları sağlamak için, POH'nin önlenmesi ve yönetimi, ameliyat öncesi risk değerlendirmelerini, perioperatif vücut sıcaklığının izlenmesini, çevresel sıcaklığın kontrolünü ve kapsamlı ısıtma protokolleri ve kontrol listelerinin geliştirilmesini içermelidir. Sonuç: Bu derleme, klinisyenler için pratik bir kılavuz sağlamayı amaçlayarak, POH için risk faktörleri ve önleme stratejileri ile ilgili son çalışmaları ve teknolojik gelişmeleri incelemektedir.
