The goal of this observational study is to assess the size and location of cutaneous sensory block area after dual laparoscopic assisted transverse abdominis plane block (L-TAP) with ropivacaine in patients undergoing laparoscopic cholecystectomy.
L-TAP is applied as a medial subcostal infiltration between midclavicular and central sternal lines and a lateral subcostal infiltration between midclavicular and anterior axillary line bilaterally.

| Measure | Description | Time Frame |
|---|---|---|
| Cutaneous Sensory Block Area (CSBA) | Assessment of the CSBA was done within the duration of the cutaneous sensory effect of the laparoscopic transverse abdominis plane block. A gauze dipped in alcohol was tapped on the skin of the abdominal wall from the midsagittal line using a star-shaped approach with its center at the umbilicus to indicate cutaneous sensory changes in cold perception. Changes were marked on the skin, confirmed twice, and a connecting line drawn to determine the CSBA. The was size of the CSBA was calculated, and the location (supraumbilical or infraumbilical and medially or laterally to a vertical line through the anterior superior iliac spine. | 1.5 hours postoperatively |
