Abstract: [Abstract] Object To expore how to relieve the sufferings of patients during the operation of inguinal hernia repair using ultra-prolene hernia system under local anaesthesia and prevent postoperative pain in the inguinal region. Methods The mixed solution, consisted of 2% lidocaine (15mL) and 0.75% bupivacaine (5mL) or 1% ropivacaine (10mL), and diluted to 60 to 65 mL with saline, used as a local anaesthetic. Before separating preperitoneal space (Brogros space), 10 to 15 mL of the local anaesthetic was injected into the space for local infiltration (group B, n=77). Assessment of pain extent during suturing and fixing mesh was determined by numerical rating scale (NRS). 20 patients without undergoing injection of local anaesthetic were as controls (group A). Results All of controls (20/20,100%) felt apparent pain（NRS≥4）during separating preperitoneal space in group A, however only 6 cases in group B showed apparent pain (7.79%). The difference was significantbetween two groups (P<0.01). During suturing and fixing mesh, 18.56% patients (18/97) in group B felt pain of ligation, and the pain relieved promptly after removing the stitch causing pain. The operative time, length of hospital stay, blood loss, postoperative pain intensity and duration, complications, and recurrence rate between two groups had no significant differences (P>0.05). Conclusions The method that injecting the local anaesthetic into Brogros space for local infiltration during operation can alleviate the pain caused by performance of separating preperitoneal space. During inguinal hernia repair under local anaesthesia, informed the pain on patients when suturing and fixing mesh is helpful to prevent pain causing by ligation.
