Pre-warmed Intravenous Fluids and Monitored Anesthesia Care

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to compare effect of pre-warmed intravenous fluids on the early outcomes in ambulatory patients undergoing monitored anesthesia care.

Detailed Description
-----------------
Monitored anesthesia care (MAC) has been increasing in fast track anesthesia for ambulatory or outpatient surgery. MAC provides lower anesthetic agents than general anesthesia, however it has been shown to result high anesthetic complication rate because of negligent monitoring. Therefore, aim of this study is to investigate the effect of pre-warmed intravenous fluids on the core body temperature and the early outcomes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tympanic membrane temperature | Preoperative dehydration will be supplemented with 10ml/kg of lactate Ringer's solution at the beginning of the anesthetic induction. 30 min after anesthetic induction is nearly after administering the fixed volume. | 30min after anesthetic induction | 

Secondary Outcome Measures

| --- | --- | --- |
| Postoperative chilling and shivering | Degree of chilling and shivering will be evaluated at the postanesthesia care unit after the surgery. | on arrival at the postanesthetic care unit ( 1hour after the anesthetic induction) |
