Abstract
BackgroundEndotracheal intubation in severely injured patients is known to be a risk factor for systemic complications. We aimed to examine the changes in intubation rates and durations in severely injured trauma patients, and rates of the systemic complications associated with ventilation changes by using a large trauma registry over the period of 13 years.MethodsPatient demographics, Injury Severity Score (ISS), ventilation days, ventilation free days (VFD), and prevalence of systemic complications (sepsis and multiple organ failure (MOF)) were obtained from the TraumaRegister DGU® and were compared over the study period.ResultsDuring the study period (2002 – 2014), 35,232 patients were recorded in TraumaRegister DGU®. 72.7 % of patients (n = 25,629) were intubated, and 27.3 % (n = 9603) of patients did not require mechanical ventilation throughout their hospital stay. The mean age was 48 ± 21 years, mean ISS was 27.9 ± 11.5, mean length of ICU stay was 11.7 ± 13.8 days, mean time on mechanical ventilator was 7.1 ± 11.3 days, and mean ventilation free days (spontaneous respiration) was 19.5 ± 11.9 days. We observed a reduction in the intubation rates (87.5 % in 2002 versus 63.6 % in 2014), and early extubation (10 ventilation days in 2002, and 5.9 days in 2014) over time.ConclusionOur study reveals a reduction in intubation rates and ventilation duration during the observation period. Moreover, we were able to observe decreased incidence of systemic complications such as sepsis over the 13 year study period, while no changes in incidence of MOF were registered. The exact relationship can not be proven in our study. This needs to be addressed in further analysis.
Highlights
Endotracheal intubation in severely injured patients is known to be a risk factor for systemic complications
Mechanical ventilation is a criteria for intensive care unit admission, when there is a clinical sign that the patient cannot maintain or suitably protect their airway, or maintain adequate oxygenation or ventilation [1]
Demographic data & clinical outcomes Over the 13 year study period, 35,232 trauma patients admitted to the Intensive Care Unit (ICU) were enrolled in the study
Summary
Endotracheal intubation in severely injured patients is known to be a risk factor for systemic complications. We aimed to examine the changes in intubation rates and durations in severely injured trauma patients, and rates of the systemic complications associated with ventilation changes by using a large trauma registry over the period of 13 years. Studies have reported that intubation is a risk factor for ventilator-associated pneumonia and pulmonary infections [2]. Pulmonary infections may trigger the development of systemic complications, such as Factors that can affect pulmonary function include concurrent chest trauma and altered mental status [7, 10]. Endotracheal intubation in trauma patient with a GCS ≤ 8 is recommended in both pre-hospital and in-hospital settings [11]
