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.

Interventions

PROCEDUREUltrasound-guided subcostal transversus abdominis plane block (US-TAP)

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.
