Meta-Analysis of Post-Intubation Hypotension: A Plea to Consider Circulation First in Hypovolemic Patients

摘要

Hypovolemic patients can develop postintubation hypotension (PIH). Our objective is to review the literature regarding PIH and the association with mortality. We searched MEDLINE from inception to February 2018. A meta-analysis was performed to assess the effect of PIH on mortality. The results of the meta-analysis were reported in forest plots of the estimated effects of the included studies with a 95 per cent confidence interval. Heterogeneity was evaluated using the I2 test, which corresponded to low (I2 < 25%), medium (I2 5 25-75%), and high (I2 > 75%) heterogeneity. We identified 243 records. Four studies were included in the meta-analysis. The studies reported 2044 patients with 36.8 per cent (n 5 753) developing PIH. Data indirectly reflecting the hemodynamic status were available in three studies (n 5 1117 patients). Overall mortality was 24.6 per cent (n 5 503) and was significantly higher in patients that developed PIH [mortality, n (%): PIH 5 250/753 (33.2%) vs 253/1291 (19.6%), P < 0.001]. Patients that develop PIH have an increased mortality. Considering a targeted resuscitation in hypovolemic patients is pivotal to minimize PIH.
