Multivariate analysis and nursing intervention strategies for intraoperative pressure ulcers in patients undergoing craniocerebral microsurgery.

[OBJECTIVE] This study aimed to investigate the various influencing factors for intraoperative pressure sores in patients with craniocerebral microsurgery and provide nursing intervention strategies for surgical pressure sores in a clinical operating room.

[METHODS] This was a case-control study on 2157 patients who underwent craniocerebral microsurgery in the craniocerebral department of the hospital between November 2021 and November 2022. Of these, 62 patients with intraoperative pressure sores were compared with 248 patients without pressure sores during the same period using a 1:4 case-control method. A logistic regression model was used to analyze the effect of possible factors on pressure sores in an operating room.

[RESULTS] The incidence of pressure sores in craniocerebral microsurgery was 2.87%. The logistic regression analysis showed that skin at the pressure site [odds ratio (OR) = 1.759, 95% confidence interval (CI): 1.137-2.721], surgical position (OR = 1.727, 95% CI: 1.338-2.228), intraoperative body temperature (OR = 2.229, 95% CI: 1.229-4.042), and surgical time (OR = 2.009, 95% CI: 1.221-3.303) were independent factors for the occurrence of intraoperative pressure sores.

[CONCLUSIONS] The high-risk factors for pressure sores in craniocerebral microsurgery included fasting time, surgical position, intraoperative temperature, and skin at the pressure site. Targeted attention and protection had a positive effect in preventing intraoperative pressure sores in patients who underwent craniocerebral microsurgery.
