TAP-study

Hernia inguinal repair is the most common operation performed by general surgeons in the Netherlands. One of the most common complications after hernia repair is postoperative and chronic pain. Postoperative pain is an expected but indesirable effect after an operation, which can result in an prolonged hospital stay or longer time to return to full normal daily activities. Thera are indications that an insufficiant treatment of postoperative pain is a risk factor for persistant or chronic pain after open hernia repair. The objective of this study is to determine, whether the use of an perioperative echo guided unilateral TAP block has an superior effect on postoperative pain after open hernia inguinal repair compared to wound infiltration with a long acting local anesthetic. There wil be no further analysis in this study regarding the relation of open hernia repair and chronic pain

Is a transversus abdominis plane block more effective regarding postoperative pain than perioperative wound infiltration with a long acting local anesthetic for a group of patients for open inguinal hernia repair
