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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| warmer temperature | Experimental | To compare the incidence and intensity of pain on injection that is caused by propofol in warm temperature（27℃） versus normal temperature(23℃). |
|
| normal temperature | Placebo Comparator | The purpose of this study is to compare the incidence and intensity of possible pain on injection as well as patient satisfaction caused by propofol in different room temperature(27 VS 23). |

| warmer temperature | Behavioral | Patients before general anesthesia induction will send to warmer operation Injection pain was accessed with (Visual analogous scale)VAS. |
|
| Measure | Description | Time Frame |
|---|---|---|
| intensity of injection pain | intensity of injection pain was reported by patient themselves before loss their awareness. | 3 months |
| numbers of lidocaine rescues for severe injection pain | when unbearable injection happens,patient could ask for stop and 20mg lidocaine was injected as rescue treatments. | 3 months |

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.

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.
