• Status: Completed
• Phase: N/A

• Healthy volunteers: Not accepted

Summary

The purpose of this study was to compare the temperature changes of the upper extremities when using local anesthetic of various volume (4ml, 6ml, 8ml) in the ultrasound guided stellate ganglion block.

Detailed description

One pain physician performs all US-guided stellate ganglion block(SGB)s, who is not involved in evaluating study variables. Electrocardiography, noninvasive blood pressure, heart rate, and peripheral oxygen saturation were monitored for all patients before, while, and after conducting procedure. For US-guided SGB, patients are supine positioned, and skin preparation on injection site is done with chlorohexidine. Procedure is conducted under ultrasound guidance at C6 level. 4ml, 6ml, and 8ml of 1% lidocaine is injected for the each group, respectively. Syringes are prepared by one nurse who do not involved in other steps of this study. Temperature measurement is conducted 4 times (before US-guided SGB and after 10, 20, and 30m from SGB) at both hands, face, axillar by one person who's not involved in other measuring in the study.

Conditions

• Neuropathic Pain
