Аннотация:A quality review revealed pressure ulcers at the ala of nose in 16 cases (2.2%) over 3 years. We therefore retrospectively investigated the risk factors for alar pressure ulcers from nasal tubes. Male gender was the highest risk factor (odds ratio = 9.1411; 95% confidence interval = 1.680-170.58), and the second highest risk factor was duration of anesthesia (odds ratio = 1.0048/min of anesthesia; 95% confidence interval = 1.0034-1.0065). Male gender and duration of anesthesia appear to be risk factors for nasal tube pressure ulcers at the ala of nose in patients.
