Objective:
The aim of this study is to investigate the risk factors of postoperative pressure ulcer (PU) development after liver resection with a long surgical duration.
Materials And Methods:
A retrospective analysis was performed of patients who underwent a liver resection with a surgical duration greater than 2 hours between January 2015 and December 2016 at a tertiary referral hospital in eastern China. Univariate analysis and multivariate logistic regression were used to analyze the independent risk factors for postoperative PUs.
Results:
Of the 128 patients included in the study, 11 (8.6%; 95% confidence interval [CI], 4.4%-14.9%) developed a stage 1 PU. Univariate analysis showed albumin on admission, diabetes mellitus complication, length of surgery, and intraoperative blood loss were all significantly different between the developed PU group (n = 11) and no PU group (n = 117; P ⟨ .05). However, multivariate logistic regression showed length of surgery (odds ratio [OR] = 1.026; 95% CI, 1.008-1.146) and intraoperative blood loss (OR = 1.014; 95% CI, 1.009-1.124) as only the independent risk factors for PU development after liver resection with a long surgical duration.
Conclusions:
These results showed length of surgery and intraoperative blood loss were independent risk factors for PU after liver resection with a long surgical duration. Use of PU prevention strategies are recommended for patients who undergo liver resection with massive intraoperative blood loss and long surgical duration.
