Transversalis Fascia Plane Block for Laparoscopic Inguinal Hernia Repair

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.

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.

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.
