Study Details

Brief summary:

Pain relief after open inguinal hernia repair could be improved by administration of TAP block or ilioinguinal/iliohypogastric nerve block. It is unclear which one works better. The investigators hypothesize that doing TAP block closer to the middle of the abdomen would result in improved pain relief due to simultaneous block of ilioinguinal/iliohypogastric nerves.
