Cutaneous Sensory Block Area of the Subcostal Ultrasound-Guided Transversus Abdominis Plane Block

NCT05826093 | Completed

• 1 other identifier: CSBA-SUSTAP
• Study Type: observational
• Target: 30
• Locations: 1 country

Brief Summary

Patients planned for elective laparoscopic cholecystectomy received a peroperative ultrasound-guided subcostal transversus abdominis plane block (USTAP) at the beginning of the procedure. At T90 minutes after the end of anaesthesia the cutaneous sensory block area (CSBA) was measured using cold sensation and mapped with a sterile marker. The CSBA was photodocumented and the area calculated.

Conditions

Postoperative Pain

Keywords

Transversus abdominis plane block

Outcome Measures

Primary Outcomes (1)

• Cutaneous Sensory Block Area

  The area of the dermis which is blocked to sensory stimulus such as pain, heat and cold.

  90 minutes postoperatively or 150 minutes after US-TAP application

Patients planned for cholecystectomy

Patients planned for elective laparoscopic cholecystectomy received a peroperative ultrasound-guided transversus abdominis plane (TAP) block at the beginning of the procedure.

Procedure: Ultrasound-guided subcostal transversus abdominis plane block (US-TAP)

Interventions

Ultrasound-guided subcostal transversus abdominis plane block (US-TAP) PROCEDURE

US-TAP is a peripheral nerve block applied for postoperative pain relief. Subcostal refers to the approach which can also be lateral or posterior. In this trial the subcostal approach was used.

Patients planned for cholecystectomy
