Background and Goal of Study: Since 2004, inguinal hernia repair must be done as day case in Germany. Yet it is one of the most painful procedures in ambulatory general surgery (1).
Materials and Methods: We studied 40 patients undergoing open hernia repair (20 with inguinal field block (IFB) and 20 without (w/o); age 55 ± 18 yrs). All patients received general anesthesia with Propofol/Remifentanil infusion and a PCA-i.v.-system with Piritramid. The block was performed pre-incisional after induction with 40ml Bupivacain 0.25%. We recorded pain (VAS 1-10) in rest and-activity, Piritramid consumption (PC), patients satisfaction (PS), side-effects and recovery (PONV, dizziness, tiredness) (−2 to +2; worse-best), delayed discharge (DD), anesthetic and surgical time.
Results: Data (mean) are shown in the Table.
Conclusion(s): The IFB combined with general anesthesia is effective against pain and comfortable for the patient in ambulatory surgery. There is no extra time consumption nor are there any extra side effects. Without IFB, there is a higher risk of delayed discharge.
