[Effect of hydrogen peroxide on anti-infection and reducing postoperative drainage in multi-segmental lumbar surgery].

OBJECTIVE

To investigate the effect of hydrogen peroxide on anti-infection and reducing postoperative drainage in multi-segmental lumbar surgery.

METHODS

A clinical data of 510 patients with multi-segmental lumbar degenerative diseases who were treated with surgery between January 2017 and January 2018 was retrospectively analyzed. In study group, the incisions of 230 cases were washed with hydrogen peroxide before suture. In control group, the incisions of 280 cases were washed with normal saline before suture. There was no significant difference in gender, age, lesion type, disease duration, operative segment, and other clinical data between the two groups ( >0.05). The operation time, intraoperative blood loss, postoperative drainage volume, and postoperative incidence of infection were recorded and compared between the two groups. The Centers for Disease Control and Prevention (CDC) standard was used to evaluate infection, which was divided into superficial infection and deep infection.

RESULTS

All operations completed successfully. There was no significant difference in operation time and intraoperative blood loss between the two groups ( >0.05). The postoperative drainage volume in the study group was significantly less than that in the control group ( =-2.990, =0.005). A total of 13 patients developed infection after operation, including 10 cases of superficial infection (2 cases in the study group and 8 cases in the control group) with the infection time of (7.3±1.5) days, and 3 cases of deep infection (all in the control group) with the infection time of (16.6±3.1) days. The incidences of superficial and deep infections in the study group were lower than those in the control group, but there was no significant difference between the two groups ( =2.595, =0.123; =0.256). All the superficial infections were infection and recovered after active dressing change. Among the patients with deep infections, 2 cases were infected by and 1 case was infected by ; and the incisions healed after being washed and sutured thoroughly, and active dressing change.

CONCLUSION

The incidence of postoperative infection and postoperative drainage volume can be reduced by washing the incision with hydrogen peroxide in multi-segmental lumbar surgery.
