RESUMEN
A pulmonary artery catheter is an important tool for the monitoring of hemodynamics in patients. Unfortunately, misplacement of a catheter tip may occur in the vasculature local to the intended placement. Misplacement of the catheter can be further complicated by entrapment at the unintended destination. We present a case of a misplaced and entrapped pulmonary artery catheter in a patient with worsening pulmonary disease. After multiple unsuccessful attempts to float the catheter, it was partially retracted and found to be stuck. Imaging showed the tip terminating in the right internal jugular vein at the level of the jugular foramen. It was initially suspected that the catheter had become looped, knotted, or otherwise entangled within the vasculature of the skull and surgical removal would be necessary. Before surgical removal was performed, it was instead determined that the catheter had become kinked and entrapped at the end of the introducer sheath, and noninvasive removal was accomplished by first removing the introducer sheath.
RESUMEN
Transfusion-related acute lung injury (TRALI) is a life-threatening complication of transfusion of blood products. A case of severe TRALI secondary to infusion of fresh frozen plasma in the intensive care unit is discussed. Additionally, the aetiology and pathogenesis of this relatively under-diagnosed and under-reported clinical entity is reviewed. It is our conclusion that proper diagnosis and reporting is necessary for prompt and appropriate treatment of the patient and to prevent additional reactions in other patients.

A 73-year-old man with multiorgan failure requiring mechanical ventilation and haemodialysis developed herpes labialis infection during his stay in the ICU. This was treated with enteral acyclovir. He developed persistent neurologic impairment soon after acyclovir administration, which, over the course of seven days, progressed to coma, the aetiology of which was unclear. The computed tomograph (CT) of the brain and the cerebrospinal fluid (CSF) examination was normal. The electroencephalogram (EEG) showed generalized slowing. The possibility of acyclovir neurotoxicity was considered and the drug was discontinued. Haemodialysis was instituted and the patient made a complete neurological recovery. We believe that this is the first reported case of coma due to enteral acyclovir.
