Abstract

Shivering after anesthesia is one of the unpleasant and undesirable complications after anesthesia; This complication occurs much more often in women than men, and female gender is one of the risk factors; Other risk factors have been reported differently in different populations; The aim of this study was to evaluate shivering-related factors after general anesthesia in gynecological surgery. This descriptive study was conducted during 2018 with the participation of 448 women candidates for gynecological surgeries. The prevalence of shivering as well as the factors affecting shivering in all patients were measured and recorded from the moment of entering the recovery unit, and finally the relationship between the available data and shivering after anesthesia was investigated. The prevalence of chills in our study was 18%; Factors such as the size of the surgical site, increasing the length of anesthesia, general anesthesia, anesthesia gas intake and atropine intake are effective factors in the occurrence of shivering after gynecological surgery. Finally, it can be concluded that the importance of the three agents of isoflurane used to maintain general anesthesia, intravenous injection of higher volume intravenous crystalloid fluids, and spinal anesthesia, respectively, increased the risk of postoperative shivering in anesthesia. ; Hypothermia, on the other hand, was not associated with chills.
