Transversus abdominis plane block
Brief summary
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.

| Cutaneous Sensory Block Area (CSBA) | 1.5 hours postoperatively | 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. |
