Acute Respiratory Failure
Conditions
Keywords
Pressure ulcer, Noninvasive ventilation
Brief summary
To assess risk of skin pressure lesions in patients treated with noninvasive mechanical ventilation.
Detailed description
Noninvasive ventilation improves the outcome of patients with acute respiratory failure; however patient's discomfort may be responsible for up to a fifth of failures. Scant literature exists on NIV-related pressure ulcers and their determinants. Aim of the study is to seek for determinants, if any, associated with the development of pressure ulcers related to noninvasive ventilation. Study design: observational. Patients treated with NIV from December 2009 to December 2011 will be analyzed. Main end-points: to seek for variables associated to the development of NIV-related pressure ulcers in patients with acute respiratory failure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Risk of skin pressure ulcers in patients treated with noninvasive ventilation for acute respiratory failure. | Risk of pressure ulcers within 72 hours from noninvasive ventilation beginning. | Skin lesions were classified as follows: * reddening, * loss of skin integrity, * necrotic lesion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of skin pressure ulcers in patients treated with noninvasive ventilation. | Incidence of skin pressure ulcers. Patients will be followed during duration of high dependency unit stay for an average length of stay of 7 days. | Characterization of skin lesions during noninvasive ventilation in patients with acute respiratory failure. |
