Development of inadvertent intraoperative hypothermia: the possibilities of clinical prognosis

Abstract

Inadvertent intraoperative hypothermia is known to increase the risk of intra- and postoperative complications. Its prediction and subsequent prevention is an acute and clinically meaningful problem. The aim of research is to determine the predictors of inadvertent intraoperative hypothermia development. Ascertaining prospective open-label study of temperature homeostasis in 100 surgical patients has been carried out. During the study, patients were divided into two groups, depending on the presence or absence of inadvertent intraoperative hypothermia. In processing of the study results was indicated the method of normalization of intense values and risk of sign realization by E. N. Shyhan. It was found out the occurrence rate of inadvertent intraoperative hypothermia that makes up 62%, identified its prognostic criteria including time-urgent operations, midline laparotomy, duration of the operation over 60 min, medication with barbiturates, myorelaxants, artificial lung ventilation, female sex, elderly age over 60 years, body mass index below 18.5 kg/m2.
