Intubation and In-Hospital Mortality After Trauma With Glasgow Coma Scale Score Eight or Less- A Cohort Study

Introduction: Most trauma societies recommend intubating trauma patients with Glasgow Coma Scale (GCS) scores <= 8 without robust supporting evidence. We examined the association between intubation and 30-d in -hospital mortality in trauma patients arriving with a GCS score <= 8 in an Indian trauma registry. Methods: Outcomes of patients with a GCS score <= 8 who were intubated within 1 h of arrival (intubation group) were compared with those who were intubated later or not at all (nonintubation group) using various analytical approaches. The association was assessed in various subgroup and sensitivity analyses to identify any variability of the effect. Results: Of 3476 patients who arrived with a GCS score <= 8, 1671 (48.1%) were intubated within 1 h. Overall, 1957 (56.3%) patients died, 947 (56.7%) in the intubation group and 1010 (56.0%) in the nonintubation group, with no significant difference in mortality (odds ratio = 1.2 [confidence interval, 0.8-1.8], P value = 0.467) in multivariable regression and propensity score -matched analysis. This result persisted across subgroup and sensitivity analyses. Patients intubated within an hour of arrival had longer durations of ventilation, intensive care unit stay, and hospital stay (P < 0.001). Conclusions: Intubation within an hour of arrival with a GCS score <= 8 after major trauma was not associated with differences in -hospital mortality. The indications and benefits of early intubation in these severely injured patients should be revisited to promote optimal resource utilization in LMICs. (c) 2024 The Author(s).
