To evaluate the association between standard post-intubation hypotension (< 90mmHg) and in-hospital mortality. Secondary objectives were to evaluate the association of post-intubation hypotension and length of stay and to assess the impact of increasing post-intubation hypotension threshold to 110mmHg on hospital length of stay and 48h-mortality in patients aged ≥ 65years. Design and setting: A cohort of patients admitted in a level-1 trauma centre emergency department (ED) between November 2011 and July2016. aged ≥ 16 with available pre-intubation vital signs, intubation performed in ≤ 3 attempts with no surgical access needed. Prospective electronic data collection was used for clinical data. 48-h in-hospital mortality. hospital length of stay. Univariate and multivariate analyses. A total of 586 patients were included. The mean age was 56.3 ± 18.8years and 37% were aged ≥ 65years. Within 60min of intubation, 224 (38%) patients had at least one systolic blood pressure measure < 90mmHg and 164(28%) had at least two measures. The < 110mmHg threshold showed a total of 377 patients (64%) had at least one systolic blood pressure measure < 110mmHg and 286 (49%) had at least two measures. We found no significant difference in the risk of mortality overall and in stratified-age groups and no association with increased hospital length of stay using both post-intubation hypotension thresholds. Post-intubation hypotension was recorded in one out of three patients in the ED but we found no association between post-intubation hypotension and 48-h in-hospital mortality overall in adults or geriatric patients.
