Analysis of chest roentgenograms performed before spontaneous fragmentation and distal embolization of an implanted subclavian vein catheter revealed discontinuity of the catheter's radiopaque marker in addition to kinking of the area proximal to the breakage point. To the authors' knowledge the case presented in this article is the first report of this imaging sign before catheter fragmentation. Lateral catheter placement and early recognition of subtle imaging signs may assist in decreasing the incidence of this significant complication.

Clinical Trial Controlled Clinical Trial
Standardized pain flowsheet: impact on patient-reported pain experiences after cardiovascular surgery.
Administration of analgesics per patient request or random pain assessments may provide inadequate pain management. ⋯ Use of a standardized pain flowsheet to assess pain intensity and document pharmacologic intervention may improve pain management in postsurgical cardiovascular patients.

Comparative Study
Effect of a standardized rewarming protocol and acetaminophen on core temperature after coronary artery bypass.
Cardiac surgical patients who require hypothermic cardiopulmonary bypass experience hypothermia, normothermia, and hyperthermia during the early postoperative period. Research-based rewarming protocols are needed to manage temperature variations. ⋯ Our results indicate that mildly hypothermic subjects rewarmed with electric heating blankets during the early postoperative period have lower peak core temperatures and longer rewarming times than those rewarmed with cotton bath blankets. Acetaminophen administration at normothermia does not significantly affect peak core temperature or the onset of hyperthermia.
