Abstract

Abstract:

Objective

To investigate the effect of local ice compress on incision pain and exudation after inguinal hernia repair.

Methods

A total of 60 patients with unilateral primary inguinal hernia in the West China Hospital of Sichuan University from December 2017 to March 2018 were enrolled. They were randomly divided into two groups: ice compress group (30 cases) and control group (30 cases). All patients underwent tension-free inguinal hernia repair under local anesthesia. On the basis of routine treatment after operation, ice compress group was locally applied with extruded medical ice bag, and the control group was locally applied with non-extruded medical ice bag. The visual analogue score (VAS) degree of pain within 24 hours after operation, the amount of analgesic drugs, and the number and area of postoperative incision dressing exudation were collected and compared between two groups.

Results

The VAS scores of ice compress group were significantly lower than that of the control group at 6, 12, and 24 hours postoperatively, the difference between the two groups was statistically significant (P<0.05). Furthermore, the number of analgesics used in the ice compress group [6(20%)] after operation was significantly less than that in the control group [21(70%)], and the difference between the two groups was significant (P<0.001). There were two cases (6.7%) and 6 patients (20%) had incision dressing exudation in the ice compress group and the control group, respectively, and no significant difference between the two groups was observed (P>0.05). In patients with incision dressing exudation, the average exudation area in the ice compress group (0.30±0.71) cm² was less than that in the control group (4.18±2.54) cm². However, there was no significant difference between the two groups (P>0.05). The incision healed smoothly after operation in both groups.

Conclusion

Local ice compress provides a safe, effective and less side effect way to relieve pain for patients undergoing inguinal hernia repair, but its effect on wound exudation needs further study.
