Primary Outcome Measures

Name	Time	Method
Post Operative Nausea Vomiting Scale	Day 1	The scores of 0-3 will determine severity on the Post-operative nausea and vomiting scale.; 0 - No nausea , No vomiting; 1. - Nausea present , No Vomiting; 2. - Nausea present , Vomiting present; 3. - Vomiting \>2 episodes within 30 minutes
Bedside Shivering Assessment Scale (BSAS)	Day 1	The scores of 0-3 will determine severity on Shivering; 0 -(none) No shivering is detected on palpation of masseter, Neck, or chest muscles; 1. -(mild) Shivering localized to Neck and thorax only; 2. -(moderate) Shivering involves gross movement of the upper extremities( in addition to neck and thorax); 3. -(severe) Shivering involves gross movements of the trunk and upper and lower extremities
