The Effect of Rectus Sheath Block as a Supplement of General Anesthesia on Postoperative Analgesia in Adult Patient Undergoing Umbilical Hernia Repair.

What Was Tested

The paper reports a study of Copper (Supplement), published as a randomized controlled trial.

The aim of this randomized double-blind study was to evaluate the analgesic effect of the bilateral ultrasound guided rectus sheath block as supplement of general anesthesia on patents undergoing elective umbilical hernia repair.

Why It Was Studied

Ultrasound guided rectus sheath block can block the ventral rami of the 7th to 12th thoracolumbar nerves by injection of local anesthetic into the space between the rectus muscle and posterior rectus sheath.

Who Took Part

PubMed indexes the participants as teenagers, young adults, adults, middle-aged adults and older adults, both men and women.

After the hospital ethics committee approval, 60 (ASA I-II) adult patients scheduled for umbilical hernia repair were included in this study.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

Neither the participants nor the staff measuring them knew who was on Copper (Supplement), so expectations could not easily colour the readings.

The group I (n=30) patents received only general anesthesia.

What Was Measured

Topics PubMed links to this paper include Analgesics, Opioid, Anesthesia, General, Anesthetics, Local, Bupivacaine, Hernia, Umbilical, Herniorrhaphy and Morphine.

The authors tagged it with the keywords Ultrasound guided rectus sheath block and Umbilical hernia repair.
