Sarcopenia is a predictive factor for prolonged intensive care unit stays in high‐energy blunt trauma patients

Abstract

Aim: Sarcopenia has been increasingly reported as a prognostic factor for outcome in settings such as cirrhosis, liver transplantation, and emergent surgery. We aimed to elucidate the significance of sarcopenia in severe blunt trauma patients., Methods: We retrospectively analyzed 84 patients emergently admitted to the intensive care unit at Kyushu University Hospital (Fukuoka, Japan) from May 2012 to April 2015. We assessed the amount of skeletal muscle present according to computed tomography and its relevance to ventilation-free days, patients' length of stay in the intensive care unit, and 28-day mortality., Results: Twenty-five (29.7%) patients were defined as sarcopenic. Sixteen (19.7%) patients required 15 days or more in the intensive care unit. The major reason was a prolonged ventilation requirement due to flail chest (n = 7) or pneumonia (n = 3). Sarcopenic patients' stays in intensive care were significantly longer than those of non-sarcopenic patients (18.7 versus 6.4 days, respectively; P < 0.001). Univariate and multivariate analyses showed sarcopenia to be a significant risk factor for prolonged intensive care unit stay., Conclusion: Sarcopenia is a risk factor that predicts prolonged intensive care unit stay in high-energy blunt trauma patients.
