To explore the characteristic of occurrence and development of pressure ulcers during radical resection of colorectal cancer, and guide intraoperative pressure ulcers nursing, relieve patients′ pain, avoid the appearance of pressure ulcers, shorten hospital stays.

A study was carried out in the Second Affiliated Hospital of Harbin Medical University from January 2016 to December 2017. A total of thirty five patients who had radical resection of colorectal cancer was analysed about the clinical information of intraoperative pressure ulcer.

The overall incidence of intraoperative pressure ulcer during radical resection of colorectal cancer was 1.44%, and the ratio of patients that were more than sixty years old was higher (χ²=26.617, P<0.001) than that of under sixty years old. Predilection site was sacrococcygeal region, and most of intraoperative pressure ulcers were stage 1. Patients with more than four hours of surgery had significantly higher risk of pressure ulcers than patients within four hours of surgery (χ²=76.452, P<0.001), the difference was statistical significance.

Duration time of the operation and advanced age were the remarkable risks of pressure ulcers. And the appearance of pressure ulcers would be reduced, if time of the operation was shortened and preoperative nutritional support was adjusted.
