Comparison of the Effectiveness of M TAPA Block and ESP Block in Laparoscopic Cholecystectomy

After laparoscopic cholecystectomy, most patients experience moderate to severe pain, especially in the first 24 hours. The cause of the pain is the skin incision, the carbon dioxide insufflation given into the abdomen for laparoscopy, and the visceral peritoneum.

This pain that occurs in the postoperative period negatively affects the patient's early mobilization, wound healing, and patient comfort. While the toxic effects of nonsteroids used for pain control on the liver and kidneys are known, narcotic analgesics have side effects such as nausea, vomiting, and addiction. In recent years, trunk blocks have begun to be used frequently for pain control in abdominal surgery. Although blocks such as erector spina plane (ESP), paravertebral (PVB), and transverses abdominis plane (TAP) are frequently applied, there are differences in terms of their effectiveness and duration. On the other hand, it is important to give the patient a suitable position for the application.

Modified-thoracoabdominal nerve block (M-TAPA), which is applied especially in the supine position and is easier to apply compared to other blocks, has started to be applied as an alternative method.

In our study, we aimed to compare the effectiveness and duration of the MTAPA block compared to other trunk blocks such as ESP.
