Determine the effects of two decurarization methods on the thermoragulation of patients received general anesthesia

Hypothermia is mostly encountered a thermoregulatory disorder during general anesthesia. Aim of the study is to determine the effects of two decurarization methods on the thermoragulation of patients received general anesthesia. After obtainig Gaziantep University Faculty of Medicine Ethics Committee approval, 66 ASA I-III, male patients over 18 years old who are scheduled for elective thoracotomy included in the study. Temperature of operation room kept at standart of 22 °C. Patients who had; diabetes, coronary artery disease, thermoregulation impairing drug usage, inflammatory disease, neuromuscular muscle disease and dystrophic disorder, hypo-hyperthyroidism, Parkinson's disease, over 30 under 20 BMI, connective tissue disease (reynaud etc.) and patients who wil remain intubated after the operation were excluded from the study. Intraoperative I.V solutions administered at room temperature. Patients were heated with ( 38 ° C at medium setting ) air blowing blankets. After TOF value obtained at the end of the operation decurarization achieved with 0,02-0,05 mg/kg neostigmine in group N and 3 mg/kg sugamadeks in group S. Patients were covered with a single layer of cotton blanket in the postoperative care unit. Core temperatures of tympanic membrane and peripheral skin temperatures of sternum and 1/3 part of the upper arm were measured and recorded at 15, 30, 45, 60, 90 and 120 minutes after extubation. There was no significant difference between the groups with regard to demographic data, preoperative temperature and operation times. Core temperature of the tympanic membrane and skin temperatures measured at the chest and arm measured at the first two hours after extubation were similar between the groups (p> 0.05). It was concluded that decurarization agents had no effect on spontaneous postoperative central and skin temperatures in the actively heated patients at equal intraoperative temperatures. Whereas in the patients received sugammadex peripheral skin temperature of arm returned earlier to preoperative control temperature levels than patients received neostigmine.
