Unintentional intraoperative hypothermia in oncological surgery and maintaining normotherapy as prevention of cardiac complications: the current state of the issue

A review is done of the latest research on unintentional intraoperative hypothermia (UIH) in oncological surgery, as well as its contribution to cardiac complications. Data are presented on the risk factors for developing UIH, the impact of surgery duration and type, as well as different anesthesia types and methods on the stage of the patient's hypothermia. Data on the relationship between the severity of UIH and the surgical profile of a patient and the patient's comorbidity were studied. It was revealed that cancer patients are at risk of developing UIH in the perioperative period, indicating the importance of preventing hypothermia during the surgery and anesthesia. The results of research on the undesirable effects of UIH, the impact of hypothermia on the development of various events, including cardiac complications, were analyzed. Data on the prevention of UIH and the methods of its prevention were systematized. The potential of maintaining the patient's normothermia for reducing the risk of developing cardiac complications in the immediate postoperative period is shown.
