Postoperative pain, postoperative pain, pain
Laparoscopy is a minimally invasive technique that is most frequently performed during upper abdominal surgery. The laparoscopy technique is considered to be superior to open surgery due to lower postoperative pain and early recovery [Postoperative pain is among the primary causes of reduction in respiratory function after upper abdominal surgery [Although the conventional method of the TAP block is the posterior approach, the subcostal TAP block has been recently reported to induce an effective analgesia for the upper abdominal incisions [An additional technique to provide analgesia to the anteromedial abdominal wall is the rectus sheath block, first described in 1899 by Schleich. This technique targets the area between the rectus abdominis muscle and the posterior rectus muscle sheath. It blocks the anterior cutaneous branches of the intercostal nerves (at T7-T11) and therefore is well suited for postoperative analgesia for midline abdominal incisions [The aim of the current study was to compare the efficacy of combinations of various peripheral blocks on pain intensity and the use of pain killers, shortly after LC. Tap and subcostal TAP as standalone blocks were compared to the combination of subcostal TAP + TAP blocks and subcostal TAP + rectus sheath blocks.
