Injection Site Irritation, Propofol Syndrome, Temperature Change, Body
Conditions
Brief summary
Propofol injection pain will be surfed by up to 70-80 percentage by the Patients who induced by propofol. Temperature of Operating room was set to a certain range in normal clinical practice, which is 22- 26 centigrade. Warm feeling will make skin vassal dilated and more blood will pass through to bring more heat out of our body. It had been reported that a bigger venous vessels will get less propofol injection pain. The investigators hypothesis that Patients who stayed in a warmer room temperature will surf less injection pain while compare to a normal setting room temperature.
Interventions

Patients before general anesthesia induction will send to warmer operation Injection pain was accessed with (Visual analogous scale)VAS.

Masking description
Patients will not knowing the exact temperature of the room,thought they will have their own feeling about it. Data was collecting with a anesthesia nurse who do not know what will do with these data. data were assessed to an anesthesiologist who did not know the Group allocation.
Intervention model description
patients for observation will sent to a warmer operating room,while Patients in controled Group will send to normal setting operating room at about 23 centigrade.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| intensity of injection pain | 3 months | intensity of injection pain was reported by patient themselves before loss their awareness. |
| numbers of lidocaine rescues for severe injection pain | 3 months | when unbearable injection happens,patient could ask for stop and 20mg lidocaine was injected as rescue treatments. |
| incidences of injection pain | 3 months | Numeric Visual Analog Scale of injection \>2 was counted as injection pain happens,the total incidence of injection was compared in two groups. |
