Brief summary

Objective: This study aimed to compare the effects of two different local anesthetics with different baricity used in spinal anesthesia on thermoregulation. Materials and Methods: The study was conducted on forty full-term pregnant women scheduled for elective cesarean sections under spinal anesthesia. At an operating room temperature of twenty-four degrees Celsius, peripheral body temperature was measured using temperature probes attached to the lower medial parts of the same side's lower and upper extremities, and central body temperature was measured with a tympanic thermometer. Isobaric levobupivacaine and hyperbaric bupivacaine were used in spinal anesthesia applications. After spinal anesthesia, tympanic temperature, arm and leg temperatures, mean arterial pressure, heart rate, and oxygen saturation were measured and recorded at baseline, the first, third, and fifth minutes, and every five minutes thereafter until the end of surgery.
