About this trial

Cholecystectomy is the most frequently performed abdominal surgery in developed nations, with laparoscopic cholecystectomy being recognized as the gold standard technique for treating gallstones.

The efficacy of TAP block for pain relief has been well-documented following laparoscopic cholecystectomy procedures. Recently, m-TAPA block has emerged as an alternative analgesic technique for abdominal surgeries.

This study aims to evaluate and compare the effectiveness of these two analgesic methods in managing postoperative pain after laparoscopic cholecystectomy.

Eligibility criteria

Anesthesiologists (ASA) I-II-III according to the ASA risk classification.

Disqualifiers

patients with coagulopathy,

patients with signs of infection at the block application site,

patients using anticoagulants,

Trial design

Design model

Parallel

Treatments tested in this trial

modified thoracoabdominal nerve block through perichondrial approach
Other intervention
After the patient fell asleep, surgery was not yet started. Following sterile conditions for bilateral M-TAPA block application, the transducer was inserted on the chondrium in the sagittal plane at the 9-10th rib level. Subsequently, a deep angle was created with the probe for visualization of the underside of the costochondrium. The sonovisible needle tip was placed just below the chondrium and saline (5 ml) was injected for site confirmation. After the confirmation, 20 ml of 0.25% bupivacaine was administered for each group for a total of 40 ml of local anesthetic. Blocks were applied using an 80 mm sonovisible needle with a 6-10 MHz linear probe under the guidance of a portable ultrasound. Same procedure applied to the contralateral side.
Transversus Abdominal Plane block
Other intervention
After the patient fell asleep, surgery was not yet started. Following sterile conditions for bilateral TAP block application, USG will be placed transversely on the mid-axillary line between the iliac crest and subcostal planes. Using the In Plane technique, the block needle will be advanced into the fascial plane between the internal oblique and transversus abdominis muscles and the location will be confirmed by administering 5 ml of saline . After the confirmation, 20 ml of 0.25% bupivacaine was administered for each group for a total of 40 ml of local anesthetic. Blocks were applied using an 80 mm sonovisible needle with a 6-10 MHz linear probe under the guidance of a portable ultrasound. Same procedure applied to the contralateral side.

Trial outcomes

Primary outcomes

numerical rating scale scores

numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.

Time frame

postoperative 24 hours

Secondary outcomes

total tramadol consumption

postoperative analgesic need

Time frame

postoperative 24 hours
