Summary

Maintaining intraoperative normothermia and temperature measurement is a marker of quality of care. We know that intraoperative hypothermia is associated with an increased risk of cardiovascular events, infection of the surgical wound, a longer hospital stay, discomfort, hemorrhage and transfusion demand. Goals: To know the incidence of perioperative hypothermia in routine clinical practice in different surgical settings in a national reference university hospital. To establish if hypothermia is a risk factor for developing postoperative complications, focusing mainly on bleeding and infection of the surgical wound, in subjects aged between 18-65 years who come to the La Paz University Hospital for a surgical intervention in the Obstetrics / Plastic and Maxillofacial Surgery Services. Hospital-based cohort study. A two-year follow-up of patients between 18 and 65 years will be carried out. Those patients with haemostasis disorders and infections in the preoperative period will be excluded. Using a questionnaire on sociodemographic variables, the baseline conditions of the patients will be evaluated for inclusion in the study. Subsequently, the temperature will be measured at the beginning and at the end of the surgery, as well as during admission to the Post Anesthesia Care Unit, where the temperature normalization time will be noted in the event of hypothermia. In retrospect, those variables corresponding to the late postoperative period will be evaluated and the telephone interview will be conducted to assess the quality of care received. All the data will be reflected in the collection booklet that we present in the annex. Patient demographics, case characteristics, and temperature records were summarized using descriptive statistics. Microsoft Excel (Professional Plus 2010, version 14); it was used for data management and processing, with Stata (version 14; StataCorp LP, College Station, TX) for graphical representations and statistical tests. A multivariate analysis of potential confounding factors will be performed. These results will serve to know the incidence of hypothermia according to the usual practice in a Spanish tertiary hospital and to establish recommendations in the management of intraoperative hypothermia and its prevention.
