Chest tube drainage was measured at 6, 12, and 24 hours after surgery. The rate of transfusion and the amount of red blood cells (RBC), fresh frozen plasma (FFP), and platelets transfused were recorded.Results: A total of 237(76%) patients underwent MRI after surgery. 39 (14%, [95% CI, 10.2 to 18.0]) patients experienced severe anxiety caused by a fear of enclosed space in the MRI coil necessitating termination of the procedure. Patients with claustrophobia were on average 5 years younger. They were more likely to have diabetes mellitus and hypertension. Patients with claustrophobia had increased chest tube drainage during the postoperative period. The rate of blood product transfusion was similar between the two groups but patients with claustrophobia who were transfused received significantly more RBC and FFP than patients without claustrophobia.Conclusions: Postoperative claustrophobia and anxiety, leading to inability to undergo MRI, may be more common than previously described.Keywords: Claustrophobia, magnetic resonance imaging, cardiac surgery, bleeding Rita KatznelsonGeorge N DjaianiLeonid MinkovichLudwik FedorkoJo Carrollet alDove Medical PressarticleNeurosciences.
