Shivering manifests as long-lasting fasciculation of the jaw, head, face or muscle hyperactivity. Post anesthetic shivering is a relatively common complication that can be stressful for patients and is occasionally associated with negative outcomes. Shivering increases oxygen consumption and the risk of hypoxemia. Data collection included a detailed history and a thorough clinical examination, and entry of information into the designed proforma. Patients were subjected to routine laboratory investigations (CBC, LFT, RFT, RBS, HIV, and HbsAg) and radiological investigations (Chest X-ray and ECG). There is no statistically significant difference between both groups regarding body temperature measured at forehead (BTF) at various intervals.
