About this study

Official title: Evaluation of the Effectiveness of Transversalis Fascia Plane Block in Patients Undergoing Laparoscopic Inguinal Hernia Repair

Transversalis Fascia Plane Block (TFPB) is a trunk block that blocks the T12- L2 spinal nerves by injection of local anesthetic between the transversus abdominis muscle and transversalis fascia on the lateral abdominal wall. The block's positive effects on postoperative analgesia have been shown in many abdominal surgeries, including open-technique inguinal hernia repair.

This study aimed to investigate the effectiveness of ultrasound (US) guided TFPB on postoperative pain control for postoperative analgesia management after laparoscopic inguinal hernia repair.

Read the detailed description

Inguinal hernia repairs are one of the most common general surgical operations and are generally performed with laparoscopic technique. Even laparoscopic inguinal hernia repair results in less acute postoperative pain compared to the open technique, untreated early pain may prolong hospital stay, exacerbate general discomfort, and affect the length of recovery, which may also have social and -economic implications. Opioids, due to their potent analgesic effects are used as a component of multimodal analgesia in the postoperative period. Despite their advantages, opioids may be related to pulmonary complications, postoperative delayed recovery due to ileus, nausea, and vomiting; and prolonged hospital stay. The use of interfascial plane blocks for pain management has increased recently, as ultrasonography (USG) has become a part of daily routine. Interfascial plane blocks provide effective postoperative analgesia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transversalis Fascia Plane BlockProcedure or surgery

    After the wound closure is completed and the patient is still under general anesthesia the TFPB will be performed. As the patient is in the supine position, the high-frequency linear US probe (11-12 MHz, Vivid Q) and a 22-G 80-mm needle (Stimuplex® Ultra 360®, Braun, USA) will be placed longitudinally, 2-3 cm laterally, just above the iliac crest at the mid-axillary line. After the external oblique, internal oblique, and transversus abdominis muscles are distinguished, the common aponeurosis of the transversus abdominis and the internal oblique muscle will be found. The block needle will be directed from anterior to posterior, using an in-plane technique, the block needle will be advanced and the block location will be confirmed by injecting 5 ml of saline. Once the block location is confirmed, 30 ml of 0.25% bupivacaine (Buvicaine, Polifarma ®) will be applied between the transversus abdominis muscle and transversalis fascia.

  • Post Operative Pain ManagementProcedure or surgery

    Acetaminophen 1 gr (Paracerol, Polifarma®) intravenous (IV), and tramadol (Contramal, Abdi İbrahim®) 100 mg IV will be administered to all patients 30 minutes before wound closure. After surgery, Acetaminophen (Paracerol, Polifarma®) 1 gr IV, and tramadol (Contramal, Abdi İbrahim®) 100 mg IV will be given three times a day. Another anesthesiologist will assess patients after surgery. If the patient's pain score (NRS) is 4 or higher, IV pethidine (Aldolan, Liba Laboratory ®) 0,5 mg/kg will be given as a rescue analgesic.

  • Port Site InfiltrationProcedure or surgery

    A total of 20 ml of 0.25% bupivacaine ( (Buvicaine, Polifarma ®) will be applied to the trocar entry points by the surgeon at the beginning of the operation, before entering the trocars.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rescue analgesic use

    The primary aim is to compare the rescue analgesia amount and its time used in the postoperative 24-hour period

    Measured: Need for rescue analgesics at 1, 3, 6, 12,18, and 24 hours postoperatively.

Secondary outcomes (2)
  1. Compare postoperative pain scores (NRS scores)

    The secondary aim is to compare the pain scores at rest and with movement. Postoperative pain assessment will be performed using the Numerical Rating Scale (NRS) (0 = no pain, 10 = the most severe pain felt). The NRS scores will be recorded. Low NRS is associated with better pain control.

    Measured: NRS scores at rest and while moving will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively.

  2. Side effects and complications

    To evaluate block-related complications and side effects (allergic reaction, nausea, vomiting)- block or opioid related

    Measured: Side effects and complications will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively

Model description
Sixty patients aged 18-65 with American Society of Anesthesiologists (ASA) classification I-II scheduled for laparoscopic inguinal hernia repair operation will be included in the study. Before entering the operating room, patients will be randomly divided into two groups (Group T = TFPB group, Group K = control group), each with 30 patients.
