Brief Summary
In this project, volunteers will be recruited to cool the superficial skin of the axillary brachial plexus away from the puncture point, resulting in local peripheral nerve cooling, and observe its impact on the pain of arterial puncture.To explore the local peripheral nerve cooling treatment can produce controllable and reversible analgesic effect even if away from the wound, and provide a new nonpharmaceutical analgesic mode for clinical.

Outcome Measures
Primary Outcomes (1)
Visual Analogue Pain Scale (VAS) score of arterial puncture procedure
The larger values of the Visual Analogue Pain Scale (VAS) score of local anesthetic injection and the Visual Analogue Pain Scale (VAS) score of arterial puncture catheterization were taken as the Visual Analogue Pain Scale (VAS) score of the process of arterial puncture catheterization.(VAS ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable)
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.
Secondary Outcomes (23)
Pressure pain threshold
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.
Pressure pain tolerance
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.
The average perfusion
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.
The median perfusion
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.
The maximum perfusion
From 0 to 3 hours after the volunteers enter the pre-anesthesia holding area.

Study Arms (4)
Skin cooling to 20°C
EXPERIMENTALThe superficial skin of the right brachial plexus (superficial skin of the axillary artery at the junction of the right pectoralis major and biceps) cooled to 20°C for 15 minutes. After cooling, 1ml 2% lidocaine was injected into the superficial skin of the right radial artery. After local anesthesia, right radial artery puncture catheterization was performed. Immediately after the puncture, warm air at 35°C was applied to the cooling treatment area for 10 minutes, and the target temperature was the surface temperature of the area before cooling treatment.
Skin cooling to 15°C
EXPERIMENTALThe superficial skin of the right brachial plexus (superficial skin of the axillary artery at the junction of the right pectoralis major and biceps) cooled to 15°C for 15 minutes. After cooling, 1ml 2% lidocaine was injected into the superficial skin of the right radial artery. After local anesthesia, right radial artery puncture catheterization was performed. Immediately after the puncture, warm air at 35°C was applied to the cooling treatment area for 10 minutes, and the target temperature was the surface temperature of the area before cooling treatment.
Skin cooling to 8°C
EXPERIMENTALThe superficial skin of the right brachial plexus (superficial skin of the axillary artery at the junction of the right pectoralis major and biceps) cooled to 8°C for 15 minutes. After cooling, 1ml 2% lidocaine was injected into the superficial skin of the right radial artery. After local anesthesia, right radial artery puncture catheterization was performed. Immediately after the puncture, warm air at 35°C was applied to the cooling treatment area for 10 minutes, and the target temperature was the surface temperature of the area before cooling treatment.
No skin cooling
PLACEBO COMPARATORThe superficial skin of the right brachial plexus does not need to be cooled. After waiting 15 minutes, 1ml2% lidocaine was injected into the superficial skin of the right radial artery. After local anesthesia, right radial artery puncture catheterization was performed. There is no need to warm the radial artery after catheterization.
Interventions
According to the group, copper parts at a constant temperature of 20°C were placed on the superficial skin of the brachial plexus for 15 minutes.
According to the group, copper parts at a constant temperature of 15°C were placed on the superficial skin of the brachial plexus for 15 minutes.
According to the group, copper parts at a constant temperature of 8°C were placed on the superficial skin of the brachial plexus for 15 minutes.
According to the group, copper parts at room temperature (23°C) were placed on the superficial skin of the brachial plexus for 15 minutes.
