To investigate the effect of red light treatment on incision healing in abdominal wall hernia open surgery.

A total of 130 patients who underwent abdominal hernia surgery in the Department of Gastroenterology, Second Affiliated Hospital of Soochow University from May 2016 to May 2020 were selected as the subjects. According to the random number table method, they were divided into an observation group and a control group, with 65 cases in each group. The control group received routine dressing change nursing intervention, and the observation group underwent the combined red light treatment on the basis of the treatment for the control group. Incision suture removal time, incision healing, pain score (VAS) and complication rate were compared between 2 groups.

The incision healing time was (11.29±2.26) and (13.42±2.93) days, respectively, the differences were statistically significant (P<0.05). The wound healing degree in the observation group was significantly higher than that in the control group (Z=1.97, P=0.048). The 5 days VAS scores of the observation group and the control group were (4.17±1.53) and (5.04±1.64) points, respectively; the 7 d VAS scores were (2.98±0.83) and (3.32±0.81) points, respectively; the total incidence of complications was (3.08% vs 7.69%); the differences were statistically significant (P<0.05).

Red light therapy can effectively promote the wound healing of abdominal wall hernia open repair, alleviate the pain of patients, do not increase the additional cost, and reduce the incidence of complications.
