Postoperative Hypothermia in Surgical Patients at Azadi Teaching Hospital
Keywords:core temperature, hypothermia, anesthesia, post-operation.
Introduction: The sensation to cold, shake occurrence and shivering are events that are commonly
developed following general anesthesia administration postoperatively. Hypothermia has been considered as
the most frequent outcome of surgery underwent by anesthesia. Inadvertent hypothermia has been taken into
account as common side effect in the postoperative period immediately and it is related to wide impairments
and anomalies of different body organs. Concentration on predictive factors of hypothermia would be
important to reduce the incidence rate and correct preventable unnecessary risks for patients in the health
settings following surgical operations. The aim of study is to assess the magnitude and associated factors of
postoperative hypothermia recovery room in patients underwent general anesthesia. Methods: A hospital
based prospective cross-sectional study was conducted on200patients with different age groups of both
genders who underwent a scheduled non-cardiac surgery and general anesthesia consecutively during the
period between the October 1stand the November1st2016. Results: The study revealed that the overall core
hypothermia in the study sample was31%. The study showed that the post-operative temperatures decreased
statistically significantly in all study patients and separately in adults, children, males, or females P<0.001.
The study also revealed that the operation duration(p=0.045)and pre-operative temperature P<0.001were
predictors of post-operative hypothermia in study sample. Conclusions: The incidence of hypothermia
among study sample was not so high. A significant reduction in core body temperature of patients between pre
and post-operation times was found. Those patients with longer operation duration, lower room temperature,
and lower pre-operative temperature were at more risk of post-operative hypothermia.
