Re**us Sheath Block — underrated and highly effective.
This is one of the most consistent, easy-to-perform blocks for anterior abdominal wall analgesia. It targets somatic pain only—skin, muscle, and fascial layers—so don’t expect visceral coverage, but what it does cover, it covers reliably.
👉 Where it shines:
• Midline incisions
• Supra-umbilical coverage (where TAP starts to fall off)
• Clean supplementation to other abdominal blocks
👉 Why I use it:
• Can be performed quickly between intubation and incision
• Low technical difficulty
• Highly reproducible spread in the re**us sheath plane
👉 Best strategy: combine it
Pair this with a TAP block and you can achieve near-complete abdominal wall coverage:
• TAP → lateral abdominal wall
• Re**us sheath → midline + above T7 coverage
The TAP alone doesn’t reliably cover above T7 or the midline — this is exactly where the re**us sheath block fills the gap.
Bottom line:
Simple. Fast. Reliable.
Very underutilized for how effective it is.

Do you routinely add re**us sheath blocks to your abdominal cases, or relying on TAP alone?
