Study Details

Study Description

Brief Summary

Propofol causes injection pain is still a common clinical unsolved problem. Mixing a small amount of lidocaine with propofol or injecting lidocaine in advance can reduce the pain caused by propofol injection. Using an air warmer to warm the arm can also reduce the pain caused by propofol injection. Investors suspect that treatment with a warming patch (covering the injection site) can also reduce the pain caused by propofol injection.

Condition or Disease Intervention/Treatment Phase
  • Device: Warming patch
  • Device: Cotton patch
N/A

Detailed Description

This is a single-center randomized controlled clinical study. Purpose of this study is to explore whether the coverage of the warming patch (for 5min before injection) can reduce the pain induced by propofol injection.

The patients included in the study were randomly divided into two groups. The group W used a warming patch to cover the injection site, and the group C used a cotton pad to cover the injection site. After 5 minutes of coverage, the propofol injection was induced, and the patient's complaint of pain (calling or arm withdrawal) during propofol injection was observed, and the patient's recall of the pain score during induction after the patient recovered. After the patients regained consciousness, the data of the two groups were compared to determine whether the use of the warming patch could reduce the pain caused by propofol injection.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Warm patch

the injection site was covered with warm patch.

Device: Warming patch
The warming patch can increase the temp of injection site, result in a blood vessels to dilate, which may have some contribute to decreasing injection pain.

Placebo Comparator: Cotton patch

the injection site was covered with cotton patch.

Device: Cotton patch
The Cotton patch will cover the injection site as placebo. It dose not have the function of heating comparing to Warming patch.

Outcome Measures

Primary Outcome Measures

  1. Arm withdrawn [5min]

    When propofol was injected, the arm was withdrawn due to injection pain.

  2. Complaints of pain [5min]

    The patient complained about the pain of the propofol injection

  3. Pain score after awakening from propofol [10min]

    Let the patients give a score when they recoved from propofol induced anesthesia.

Secondary Outcome Measures

  1. Respiratory depression [5min]

    those ases when pulse oxygen saturation is less than 90%

  2. Temperature of injection site after injecting of propofol. [10min]

    Get the temperature of the back of the hand with an infrared thermometer
