Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In laparoscopic cholecystectomies, ultrasound-guided interfascial plane blocks are commonly used for postoperative analgesia. The aim of our study was to compare the postoperative analgesic efficacy of thoracoabdominal nerve block with the perichondral approach (TAPA) with transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical operations and the postoperative hospital stay is short (1). Although there is less postoperative pain in laparoscopic surgeries than in open surgeries, severe pain is a common complaint, especially in the first 24 hours. Therefore, various modalities have been tried to reduce postoperative pain (2).

In recent years, the effectiveness of ultrasound-guided interfascial plane blocks has come to the fore in the field of regional anaesthesia and pain management. There has always been a search for a regional anaesthesia method that provides effective analgesia of the anterolateral part of the upper abdomen. In addition to anterolateral blocks, such as pectoralis nerve block (PECS) and serratus intercostal plane block (SIBP), other posterior blocks like quadratus lumborum blocks and erector spinus plane blocks have been used for this purpose. TAP block is the application of local anaesthetic agents into the neurofascial space between the internal oblique and transversus abdominis muscle layers located in the anterolateral region of the abdomen. This procedure, in which the anterior branches of the 7th-12th thoracic intercostal and first lumbar (L1) nerves are blocked, is frequently used to provide pain control after operations involving the abdominal and inguinal regions (3,4).

Recently introduced thoracoabdominal nerve blockage with perichondrial approach (TAPA) has been reported to provide sensory blockade between midaxillary line and midabdominal/sternum in dermatomes between T5-T12 (5,6). In TAPA block, local anesthesia is applied to two points, the upper part of the chondrium and the lower part of the chondrium. In this way the anterior and lateral cutaneous branches of the intercostal nerves are blocked. In light of this information, our hypothesis is that the analgesic effect will be greater in TAPA block since the lateral branches of the intercostal nerves are also affected.

The aim of our study is to compare the postoperative analgesic efficacies of TAP and TAPA blocks to be applied to patients undergoing laparoscopic cholecystectomy.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The patients were randomly allocated to one of two groups using a computer-generated randomized sequence table with an allocation ratio of 1:1 and a block size of two.
Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Outcome Assessors
The study was conducted using a sealed envelope system. The sealed, opaque, sequentially numbered envelopes were opened by intervention staff who conducted induction of anesthesia and block procedure just prior to surgery. A second investigator involved in the assessment of postoperative outcomes and another investigator involved in data collection were blinded to group allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

group T

After general anesthesia induction, TAP block was applied to Group T. TAP block is the application of local anaesthetic agents to the neurofascial space between the internal oblique and transversus abdominis muscle layers located in the anterolateral region of the abdomen.

Group Type ACTIVE_COMPARATOR

Transversus abdominis plane (TAP) block

Intervention Type PROCEDURE

: It was performed under USG guidance using 30 ml of 0.25% bupivacaine with an 80 mm insulated peripheral block needle. Local anaesthetic was applied between the upper fascia of the transversus abdominus muscle and the fascia of the internal oblique muscle at the midpoint of the distance between the costal margin and the iliac crest in the midaxillary line under USG imaging guidance.

group P

TAPA block was applied to Group P. In TAPA block, local anesthesia is applied to two points, the upper part of the chondrium and the lower part of the chondrium.

Group Type ACTIVE_COMPARATOR

thoracoabdominal nerve blockage with perichondrial approach (TAPA) block

Intervention Type PROCEDURE

Under USG guidance, 20 ml of 0.25% bupivacaine was administered between the upper fascia of the transversus abdominis muscle and the lower fascia of the costochondral tissue at the level of the 9th and 10th ribs (arcus costarum) in the midclavicular line with an 80 mm insulated peripheral block needle. Then, 10 ml of 0.25% bupivacaine was injected into the upper fascia of the costochondral tissue and the lower fascia of the external oblique muscle. The block was performed by following the needle path in the ultrasound image.
