Early Tracheostomy in Severe Traumatic Brain Injury Patients: A Meta-Analysis and Comparison With Late Tracheostomy

Early Tracheostomy in Severe Traumatic Brain Injury Patients: A Meta-Analysis and Comparison With Late Tracheostomy: Objectives:

To elucidate the impact of early tracheostomy on hospitalization outcomes in patients with traumatic brain injury.

Data Sources:

Lilacs, PubMed, and Cochrane databases were searched. The close-out date was August 8, 2018.

Study Selection:

Studies written in English, French, Spanish, or Portuguese with traumatic brain injury as the base trauma, clearly formulated question, patient’s admission assessment, minimum follow-up during hospital stay, and minimum of two in-hospital outcomes were selected. Retrospective studies, prospective analyses, and case series were included. Studies without full reports or abstract, commentaries, editorials, and reviews were excluded.

Data Extraction:

The study design, year, patient’s demographics, mean time between admission and tracheostomy, neurologic assessment at admission, confirmed ventilator-assisted pneumonia, median ICU stay, median hospital stay, mortality rates, and ICU and hospital costs were extracted.

Data Synthesis:

A total of 4,219 studies were retrieved and screened. Eight studies were selected for the systematic review; of these, seven were eligible for the meta-analysis. Comparative analyses were performed between the early tracheostomy and late tracheostomy groups. Mean time for early tracheostomy and late tracheostomy procedures was 5.59 days (SD, 0.34 d) and 11.8 days (SD, 0.81 d), respectively. Meta-analysis revealed that early tracheostomy was associated with shorter mechanical ventilation duration (–4.15 [95% CI, –6.30 to –1.99]) as well as ICU (–5.87 d [95% CI, –8.74 to –3.00 d]) and hospital (–6.68 d [95% CI, –8.03 to –5.32 d]) stay durations when compared with late tracheostomy. Early tracheostomy presented less risk difference for ventilator-associated pneumonia (risk difference, 0.78; 95% CI, 0.70–0.88). No statistical difference in mortality was found between the groups.

Conclusions:

The findings from this meta-analysis suggest that early tracheostomy in severe traumatic brain injury patients contributes to a lower exposure to secondary insults and nosocomial adverse events, increasing the opportunity of patient’s early rehabilitation and discharge.
