Using a stopwatch, the investigating physician will document a "Begin Time" just after the patient and the equipment have been prepped under full sterile precautions. In both groups, the timer would start at the same point in time - - when the needle is ready to puncture the skin. Complications will also be noted by the investigating physician during and after the SCVC placement, including number of puncture attempts, success/failure of blood return from the SCVC ports, occurrence of catheter tip misplacement, arterial puncture, and incidence of hematoma, hemothorax, or pneumothorax. As per routine protocol, a post-procedure chest x-ray will be obtained and will be reviewed for evidence of complications. The final Radiology Attending interpretation of the chest xray will also be recorded.
