Comparison of Postoperative Analgesic Effects of M-TAPA and Anterior Quadratus Lumborum Blocks in Laparoscopic Cholecystectomies.
In trunk blocks, the interfascial area between the anterior abdominal wall or back muscles is targeted. Local anesthetics are used for this purpose. Since there is no blood circulation and vascularization in the interfascial areas, the absorption of local anesthetics is slow, providing long-lasting analgesia. Therefore, they are used as a part of multimodal analgesia. The effectiveness of trunk blocks can vary depending on the patient's anatomical differences and previous surgeries, but on average, analgesic effectiveness lasts for 8-12 hours. Sometimes analgesic effectiveness extending up to 24 hours has been reported.
In laparoscopic cholecystectomy operations, pain plays a role in postoperative atelectasis, pneumonia due to atelectasis, prolonged hospital stay, and discharge. To reduce the use of opioids due to their side effects such as nausea, vomiting, itching, constipation, and addiction, opioid-free analgesia is applied, and regional techniques are used. Quadratus lumborum blocks and M-TAPA blocks have been safely and easily applied in abdominal surgery in recent years thanks to developments in trunk blocks and ultrasound technology, and they are frequently preferred.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Quadratus lumborum block group | Active Comparator | Patients are placed in the lateral decubitus position. The area where the block will be applied is disinfected with povidine iodine. A convex ultrasound probe is placed on the midaxillary line above the iliac crest. By visualizing the transverse process adjacent to the psoas major and quadratus lumborum muscles, using the in-plane technique, using a 22 gauge 80 mm peripheral block needle after negative aspiration into the anterior layer of the thoracolumbar fascia anterior to the quadratus lumborum muscle muscle, 0.5-1 ml of serum After observing hydrodissection with physiological, 20 ml of 0.25% bupivacaine is injected. The same is done to the opposite side. |
|
| m-tapa block | Active Comparator | In the M-TAPA block group, with the patient in the supine position, a linear high-frequency linear ultrasound (USG) probe is angled to visualize the inferior surface of the costochondral junction at the level of the 10th costochondral cartilage. Under sterile conditions, using the in-plane technique with a 22G 80 mm peripheral block needle, the needle is advanced posterior to the 10th costal cartilage by taking the lower edge of the cartilage in the sagittal plane as the midline. After hydrodissection with 2-3 ml isotonic saline to confirm the site, 20 ml of 0.25% Bupivacaine is administered under USG guidance. The same procedure is performed on the contralateral side as well. |
