Details and patient eligibility

About

TAP was recommended by PROSPECT for further investigation as an appropriate analgesic method after open herniorrhaphy. Ilioinguinal/iliohypogastric nerve block is one of the oldest methods of analgesia. The researchers wish to investigate whether the TAP block is as effective as the ilioinguinal/iliohypogastric nerve block?
