| Popis: | Objectives Intracranial hemorrhage is a serious complication in patients receiving venovenous extracorporeal membrane oxygenation during treatment of the acute respiratory distress syndrome. We analyzed timing, outcome, and risk factors of intracranial hemorrhage in patients on venovenous extracorporeal membrane oxygenation. Design Retrospective cohort study. Setting Single acute respiratory distress syndrome referral center. Patients Patients receiving venovenous extracorporeal membrane oxygenation were identified from a cohort of 1,044 patients with acute respiratory distress syndrome. Patients developing an intracranial hemorrhage during venovenous extracorporeal membrane oxygenation therapy were compared with patients without evidence for intracranial hemorrhage. The primary objective was to assess the association of intracranial hemorrhage with 60-day mortality. Further objectives included the identification of risk factors for intracranial hemorrhage and the evaluation of clinical cutoff values. Interventions None. Measurements and main results Among 444 patients treated with venovenous extracorporeal membrane oxygenation, 49 patients (11.0% [95% CI, 8.3-14.4%]) developed an intracranial hemorrhage. The median time to intracranial hemorrhage occurrence was 4 days (95% CI, 2-7 d). Patients who developed an intracranial hemorrhage had a higher 60-day mortality compared with patients without intracranial hemorrhage (69.4% [54.4-81.3%] vs 44.6% [39.6-49.6%]; odds ratio 3.05 [95% CI, 1.54-6.32%]; p = 0.001). A low platelet count, a high positive end expiratory pressure, and a major initial decrease of Paco2 were identified as independent risk factors for the occurrence of intracranial hemorrhage. A platelet count greater than 100/nL and a positive end expiratory pressure less than or equal to 14 cm H2O during the first 7 days of venovenous extracorporeal membrane oxygenation therapy as well as a decrease of Paco2 less than 24 mm Hg during venovenous extracorporeal membrane oxygenation initiation were identified as clinical cutoff values to prevent intracranial hemorrhage (sensitivity 91% [95% CI, 82-99%], 94% [85-99%], and 67% [48-81%], respectively). Conclusions Intracranial hemorrhage occurs early during venovenous extracorporeal membrane oxygenation and is a determinant for 60-day mortality. Appropriate adjustment of identified modifiable risk factors might lower the prevalence of intracranial hemorrhage during venovenous extracorporeal membrane oxygenation therapy. |
