Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
