Summary
Inguinal hernia repair is the most common of abdominal surgical procedures and is usually
performed laparoscopically. Many factors play a role in the pain that develops after surgery
and is generally considered to be visceral pain. Phrenic nerve irritation due to CO2
insufflation into the peritoneal cavity, abdominal distention, tissue trauma, sociocultural
status, and individual factors are the factors that play a role in the occurrence of this
pain.
Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block performed with
ultrasound (US) is a new block that provides effective analgesia in the anterior and lateral
thoracoabdominal areas, where local anesthetic is applied only to the lower side of the
perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome
levels and abdominal lateral wall and may be an opioid-sparing strategy with satisfactory
quality recovery in patients undergoing laparoscopic surgery.
Oblique Subcostal Transversus Abdominis Plane Block (OSTAP) is one of the body blocks used
especially for postoperative analgesia. OSTAP, defined by Hebbard in 2010, is a subcostal
version of the Transversus abdominis plane block (TAP block), based on the injection of local
anesthetic from the lower edge of the costal margin, obliquely between the obliquus externus
and Transversus abdominis muscles.
This study aimed to compare the efficacy of US-guided M-TAPA block and OSTAP block for
postoperative analgesia management after laparoscopic inguinal hernia repair surgery. Our
primary aim is to compare postoperative pain scores (0. hour NRS), and our secondary aim is
to evaluate the use of rescue analgesics (opioids), side effects associated with opioid use
(allergic reaction, nausea, vomiting), and patient satisfaction (Likert scale).
