AIM OF STUDY:
Comparison between effect of external oblique intercostal plane block and the Oblique subcostal transversus abdominis plane block in paraumbilical hernia repair as analgesia for intraoperative and postoperative pain.
- Detailed Description
A paraumbilical hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus. If the hole is large enough there can be protrusion of the abdominal contents, including omental fat and/or bowel. These defects are usually congenital and are not noticed until they slowly enlarge over an individual's life time and abdominal contents herniate through the hole creating either pain or a visible lump on the abdominal wall. If abdominal contents get incarcerated (or stuck) in the hole this can cause pain. If the abdominal contents become strangulated by losing their blood supply from pinching or twisting those tissue will die. If it is omental fat this will cause pain and could potentially lead to an infection. If the strangulated contents are bowel then in addition to pain the individual will develop a bowel obstruction. And if the dead bowel is not surgically removed in an emergent fashion the condition could be fatal.
Postoperative pain is the major obstacle for early postoperative ambulation and increases the risk of venous thromboembolism and respiratory complications and prolongs the hospital stay. This pain is routinely managed using opiates, which are associated with several side effects, including excessive sedation and postoperative nausea and vomiting (PONV) which may increase hospital stay durations. Transversus abdominis plane (TAP) block is a regional anesthetic technique that has gradually become an alternative for postoperative pain control during laparoscopic abdominal surgeries. It involves the infusion of local anesthetic into the fascial plane of the abdominal wall.
the subcostal transversus abdominis plane block (TAP) targets the upper abdominal wall.
The EOI block represents an important modification that cover the upper lateral abdominal wall.
Oblique subcostal transversus abdominis plane (OSCTAP) block is an US-guided regional anesthesia technique that anesthetizes the nerves of the lower and upper anterior abdominal wall,specifically from T6 to L1. The OSCTAP has been described that can be performed to provide analgesia for abdominal surgery extending above the umbilicus.
