Objective: Hemodynamic instability following emergent endotracheal intubation (EETI) is a potentially life-threatening adverse event. The objectives of this systematic literature review were to document the incidence of postintubation hemodynamic instability (PIHI), to determine the definitions for PIHI used in the available literature, and to examine factors associated with PIHI in adult patients who require EETI. Data Source: Articles published in Medline (1966-August 2012. Study Selection: This systematic review included adult, inhospital studies of EETIs. Studies with nonemergent or pediatric patient populations were excluded. Data Extraction: Two authors independently performed data abstraction. Disagreements were resolved by a third party. The methodological quality of included studies was assessed with the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies. Data Synthesis: We estimated the pooled prevalence of PIHI across studies using a random effects meta-analysis. Subgroups analyzed included study design, intubation setting, geographic location of the study, physician experience, medications used for sedation, neuromuscular blockade, and definition of PIHI. Eighteen studies were analyzed, with sample sizes from 84 to 2,833 patients. The incidence of PIHI ranged from 5 to 440 cases per 1,000 intubations, with a pooled estimate of 110 cases per 1,000 intubations (95% CI 65-167). Conclusions: PIHI was found to occur in 110 cases per 1,000 in-hospital, emergent intubations. However, heterogeneity among the included studies limits the reliability of this summary estimate. Further investigation is warranted.
RÉ SUMÉObjectifs: L'instabilité hé modynamique consé cutive à une intubation endotraché ale trè s urgente (IETU) est un é vé nement indé sirable potentiellement mortel. L'examen mé thodique de la documentation avait pour objectifs d'é tablir la fré quence de l'instabilité hé modynamique aprè s intubation (IHAI), de dé terminer les dé finitions de l'IHAI utilisé es dans la documentation et d'examiner les facteurs associé s à l'IHAI chez les adultes. Source de donné es: Les articles publié s dans Medline (1966-aoû t 2012) ont constitué la source de donné es. Sé lection des é tudes: L'examen mé thodique portait sur les é tudes ayant pour objet les IETU effectué es chez les adultes, en milieu hospitalier; les é tudes portant sur les intubations non considé ré es comme trè s urgentes ou effectué es chez les enfants é taient é carté es. Extraction des donné es: Deux auteurs ont procé dé , chacun de leur cô té , aux ré sumé s analytiques des donné es. Les divergences de point de vue ont é té ré solues par une tierce partie. La qualité mé thodologique des é tudes retenues a é té é valué e selon l'é chelle de NewcastleOttawa, qui permet d'é valuer la qualité des é tudes de cohortes. Synthè se des donné es: L'estimation de la pré valence globale de l'IHAI, tiré e des é tudes retenues repose sur une mé taanalyse à effets alé atoires. Ont é té analysé s le type d'é tude, le service où ont é té eff...
