Conditions

Hypothermia; Anesthesia, Nausea and Vomiting, Postoperative

Brief summary

Intraoperative Hypothermia is a common problem, our object will be to evaluate the efficacy of forced air warmer (Model # eq-5000) for maintaining core body temperature in patients undergoing laparoscopic surgeries and its effect on postoperative nausea, vomiting and shivering.

Interventions

DEVICEBair hugger and Forces air warmer

The EQUATOR™ (EQ-5000) air-warmer is a convective warmer, with the average and maximum Contact Surface Temperatures of 39℃ & 44℃ Respectively. Temperature on this device can be set at 36℃ , 40℃ , 44℃. The 3M™ Bair Hugger ™ (SW-2003) upper body blanket is used to warm the body from head till the xiphisternum
