Clinical study of mouse nerve growth factor for injection in the treatment of incision pain after inguinal hernia repair / 中国医师进修杂志

ABSTRACT

Objective To study the feasibility of mouse nerve growth factor for injection in treatment of incision pain after inguinal hernia repair. Methods Eighty unilateral inguinal hernia patients who had underwent inguinal hernia repair were divided into 2 groups according to the sequential order with 40 cases each. The patients of odd number were divided into control group, and the patients of dual number were divided into treatment group. All patients were performed Lichtenstein tension free repair operation, and were given the basic treatment of inguinal hernia. At the 3rd d after operation, the patients in control group were given 2 ml water for injection through intramuscular injection, and the patients in treatment group were given 20 μg mouse nerve growth factor for injection through intramuscular injection. One course of treatment was 14 d. At 3 d, 15 d, 30 d, 3 months and 6 months after operation, the pain degree, the pain range, and the effect of pain on behavior was observed and evaluated according to visual analogue score (VAS), the innervation range of the inguinal region, and behavioral rating scale-6 (BRS-6) respectively. Results There were no statistical differences in VAS, pain range score and BRS-6 score 3 d after operation between 2 groups (P>0.05). The VAS, pain range score and BRS-6 score 15 and 30 d after operation in treatment group were significantly lower than those in control group, 15 d after operation(1.64 ± 0.92) scores vs. (2.28 ± 1.06) scores, (1.23 ± 0.43) scores vs. (1.61 ± 0.56) scores and (1.02 ± 0.56) scores vs. (1.57 ± 0.73) scores, and 30 d after operation(0. 98 ± 0.56) scores vs. (1.61 ± 1.04) scores, (0.87 ± 0.43) scores vs. (1.16 ± 0.56) scores and (0.86 ± 0.32) scores vs. (1.16 ± 0.73) scores, there were statistical differences (P0.05). Conclusions Injecting mouse nerve growth factor for injection is effective for pain treatment after inguinal hernia repair.
