title: Cerebrovascular events associated with infusion through arterially malpositioned triple-lumen catheter: report of three cases and review of literature.
abstract: Analysis of 10 adult patients treated from January 1998 to November 2004 for arterial misplacement of triple-lumen catheter (TLC) during internal jugular vein cannulation was performed. Three cases that developed neurologic symptoms occurring in the context of infusion through a TLC that was arterially malpositioned are presented, along with the review of literature. In 7 patients, the diagnosis of arterial misplacement was suspected by the color or flow characteristics of blood and confirmed by a combination of blood gas analysis, connecting catheter to transducer, and/or chest film. In the remaining 3 patients, intraarterial misplacement was not suspected. In these patients, the initial review of chest films by qualified physicians prior to starting infusion failed to detect malposition of the catheter. Retrospectively, subtle clues suggestive of arterially placed TLCs were found. All 3 patients developed neurologic symptoms. Initiation of neurologic workup delayed a correct diagnosis by 6 to >48 hours. A volumetric pump was used for infusion in all patients. Of the 3 patients with neurologic symptoms, 1 recovered completely, 1 became comatose, and 1 partially improved. Based on our observations and review of literature, we conclude that cursory examination of chest films to verify proper positioning of central venous catheter attempted through the internal jugular vein may fail to detect arterial malposition. Infusion by volumetric pump precludes backflow of blood in the intravenous tubing as an indicator. Neurologic symptoms concurrent with the infusion of fluids and medication should raise suspicion of accidental arterial infusion.
