简要总结
Hypothermia and shivering are common complications in patients undergoing lower abdominal surgery under spinal anesthesia. Redistribution of body heat after neuraxial blockade is the primary cause. Preoperative warming may help prevent these complications by increasing peripheral tissue temperature and reducing the core-to-peripheral gradient.
This prospective randomized clinical study will include 100 ASA 1 to 2 patients aged 18 to 50 years scheduled for elective lower abdominal surgery under subarachnoid block at a tertiary care teaching hospital.
Patients will be randomly divided into 2 groups
Group 1 Active warming Pre-warming with a forced air blanket at 43 degrees Celsius for 20 minutes
Group 2 Control Covered with a double-layered blanket for 20 minutes
Core body temperature will be measured with a tympanic thermometer, and shivering will be assessed using the Crossley and Mahajan scale. Rescue medications IV Tramadol 0.5 mg per kg Ondansetron 0.15 mg per kg will be administered if required.
Primary outcome Incidence of Intraoperative hypothermia
Secondary outcome Incidence and severity of perioperative shivering
The study aims to evaluate whether preoperative warming is effective in maintaining normothermia and reducing shivering during lower abdominal surgeries under spinal anaesthesia.
