About

The goal of this prospective observational study is compare in terms of efficiency and complications transversus abdominis plane (TAP) and Modified thoracoabdominal plane block-perichondrial approach (M-TAPA) blocks in patients undergoing laparoscopic sleeve gastrectomy. The investigators aims to examine whether M-TAPA block provides more effective analgesia than TAP block in upper abdomen surgeries, and whether there is any difference in terms of nausea- vomiting and need for additional analgesics. The participitans will be observed for postoperative 24 hours with numeric rating score (NRS), postoperative nausea-vomiting score (PNVS) and in terms of need for additional analgesic dose.

Full description

After laparoscopic sleeve gastrectomy, patients have pain due to surgery. Different analgesic methods are preferred for pain relief. One of the methods used for this purpose is regional anesthesia. Modified thoracoabdominal plane block-perichondrial approach (M-TAPA) and transversus abdominis plane (TAP) block are also plan blocks used for this purpose. TAP block is formed by injecting local anesthetic into the neurofacial space between the transversus abdominis muscle and the internal oblique muscle through the Petit triangle in the lumbar region. TAP block creates dermatomal sensory block in the lower, lower thoracic and upper lumbar abdominal afferents. It is thought that the modified thoracoabdominal plane block-perichondrial approach (M-TAPA), which is a block frequently used in upper abdomen surgeries in recent years, can provide effective analgesia in LSG surgeries. M-TAPA block is created by administering local anesthetic between the transverse abdominis muscle and the internal oblique muscle with a single injection under the costal cartilage under ultrasound guidance. With M-TAPA, analgesia can be provided in thoracic 4 and thoracic 11-12 dermatomes.

Blocking of T4-12 nerve endings may be required in LSG surgeries, since gastric innervation and thoracic inlets are located in the upper abdomen dermatomes. In studies, the use of M-TAPA block in upper abdominal surgeries may be effective in the management of analgesia in participants. In this study the investigators aimed that, compression in terms of efficiency and complications TAP and M-TAPA blocks, who is undergoing laparoscopic sleeve gastrectomy. The investigators aims to examine whether M-TAPA block provides more effective analjesia than TAP block in upper abdomen surgeries, and whether there is any difference in terms of nausea- vomiting and need for additional analgesics. After obtaining ethical committee approval (12.01.2023/1), between January 26, 2023, and May 15, 2024, 60 patients undergoing laparoscopic sleeve gastrectomy with American Society of Anesthesiologists (ASA) II-III status provide informed consent. Participants who are planing to receive M-TAPA block defines as Group M-TAPA, and those who receive TAP block defines as Group TAP, with 30 patients in each group.The participitans will be observed for postoperative 24 hours with numeric rating score (NRS), postoperative nausea-vomiting score (PNVS) and in terms of need for additional analgesic dose.
