Central Venous Catheterization: Comparison between Interventional Radiological Procedure and Blind Surgical Procedure

Central venous catheterization (CVC) is a common procedure in the perioperative period, and thrombosis is one of the well-known complications of CVC. If the thrombus comes free from the vascular wall, it may cause serious problems such as pulmonary embolism. However, in some cases of inferior vena cava thrombosis, the patient has no symptoms, and thrombus is detected accidentally. A case in which asymptomatic thrombus in the inferior vena cava was incidentally detected following removal of the CV catheter after an oral surgical procedure is described.

Abstract A concept for a sensorized medical tray in conjunction with real-time visual cues to aid medical residents in learning the steps of complicated tray-based medical procedures, such as central venous catheterization, was designed and tested as a first iteration. This paper outlines the selection of an LED screen to illuminate various medical devices and the testing of simple magnetic reed switches to use as sensors to track the movement of various medical tools from a tray. While this concept was designed around central venous catheterization, this work is translatable to any medical procedure using a pre-packaged plastic tray.

Automated Feedback

The Dynamic Haptic Robotic Trainer (DHRT) was developed to minimize the up to 39% of adverse effects experienced by patients during Central Venous Catheterization (CVC) by standardizing CVC training, and provide automated assessments of performance. Specifically, this system was developed to replace manikin trainers that only simulate one patient anatomy and require a trained preceptor to evaluate the trainees’ performance. While the DHRT system provides automated feedback, the utility of this system with real-world scenarios and expertise has yet to be thoroughly investigated. Thus, the current study was developed to determine the validity of the current objective assessment metrics incorporated in the DHRT system through expert interviews. The main findings from this study are that experts do agree on perceptions of patient case difficulty, and that characterizations of patient case difficulty is based on anatomical characteristics, multiple needle insertions, and prior catheterization.
