No summary available.

•The study was included 90 male patients aged between 18-60 years whose physical status was in the American Society of Anesthesiologists (ASA) I-II risk group and were scheduled for lower extremity surgery. In all cases, to avoid errors in body temperature measurements arising from the diurnal rhythm, body temperature measurements were taken in the morning between 08:30 and 13:00 hours.

•Patients with inflammatory diseases, diabetes mellitus, muscle disease, hypo/hyperthyroidism, cardiac, hepatic and renal diseases, Parkinson disease, Reynold syndrome, a history of using drugs that are known to affect body temperature (Beta-blockers, calcium channel blockers, clonidine, steroids, anti-epileptic, non-steroidal anti-inflammatory drugs, benzodiazepine), vertebral column anatomical disorder, bleeding diathesis, anticoagulant use, infection at the region of procedure, neurological deficits, drug and alcohol addiction, obesity, and those with allergies to local anesthetics were excluded from the study. In addition, patients whose surgery was shorter than 60 minutes and longer than 180 minutes and those surgeries where a tourniquet was used were also excluded from the study. Patients having a greater than 30% change in hemodynamic parameters during the surgery, those who needed to use a vasopressor or vasodilator, and those who required a blood transfusion were excluded from the study as well.
