The risk of fatal bleeding complications in jugular catheterization in patients with coagulopathy: A retrospective analysis of death cases in closed claims and the Medical Accident Investigating System in Japan

Background To prevent recurrence of medical accidents, the Medical Accident Investigating System was implemented in October 2015 by the Japan Medical Safety Research Organization (Medsafe Japan) to target deaths from medical care that were unforeseen by the administrator. Medsafe Japan analyzed the 10 cases of central venous catheterization-related deaths reported in the system and published recommendations in March 2017. However, the particular emphasis for the prevention of central venous catheterization-related deaths is unclear. Methods This study aimed to identify the recommendation points that should be emphasized to prevent recurrence of central venous catheterization-related deaths. We assessed central venous catheterization in 8530 closed-claim cases between January 2002 and December 2016 covered by the medical insurer Sompo-Japan. Moreover, we compared central venous catheterization-related death in closed-claim cases with death in reported cases. Results The background, error type, anatomic insertion site, and fatal complication data were evaluated for 37 closed-claim cases, of which 12 (32.4%) were death cases. Of the 12 closed-claim cases and 10 reported cases, 9 (75.0%) closed-claim cases and 9 (90.0%) reported cases were related to vascular access. Among these, 5 closed-claim cases (41.7%) and 7 reported cases (77.8%) were related to internal jugular vein catheterization (p = 0.28). Coagulopathy was observed in 3 (60.0%) of 5 closed-claim cases and 6 (85.7%) of 7 reported cases. Conclusions The risk of internal jugular catheterization in patients with coagulopathy must be carefully considered.

Axillary vein catheterization using ultrasound guidance: A prospective randomized cross-over controlled simulation comparing standard ultrasound and new needle-pilot device

Background: Real-time ultrasound (US) guidance facilitates central venous catheterization in intensive care unit (ICU). New magnetic needle-pilot devices could improve efficiency and safety of central venous catheterization. This simulation trial was aimed at comparing venipuncture with a new needle-pilot device to conventional US technique. Methods: In a prospective, randomized, simulation trial, 51 ICU physicians and residents cannulated the right axillary vein of a human torso mannequin with standard US guidance and with a needle-pilot system, in a randomized order. The primary outcome was the time from skin puncture to successful venous cannulation. The secondary outcomes were the number of skin punctures, the number of posterior wall puncture of the axillary vein, the number of arterial punctures, the number of needle redirections, the failure rate, and the operator comfort. Results: Time to successful cannulation was shorter with needle-pilot US-guided technique (22 s (interquartile range (IQR) = 16–42) vs 25 s (IQR = 19–128); median of difference (MOD) = −9 s (95%-confidence interval (CI) −5, −22), p < 0.001). The rates of skin punctures, posterior wall puncture of axillary vein, and needle redirections were also lower ( p < 0.01). Comfort was higher in needle-pilot US-guided group on a 11-points numeric scale (8 (IQR = 8–9) vs 6 (IQR = 6–8), p < 0.001). Conclusions: In a simulation model, US-guided axillary vein catheterization with a needle-pilot device was associated with a shorter time of successful cannulation and a decrease in numbers of skin punctures and complications. The results plea for investigating clinical performance of this new device.

Unusual complications of the central venous catheterization in trauma patients

Central venous catheters (CVCs) are commonly used in patients with trauma. The placement and removal of the CVCs can result in various complications regardless of the skill of the professionals. Herein, two cases of rare complications are presented— an inadvertent subclavian artery catheterization and a cerebral air embolism after a CVC removal. Moreover, practical solutions for each complication are provided in detail.

The need for multiple vascular access or preemptive central venous catheterization in patients requiring planned interhospital helicopter transport: a flight doctor’s suggestion

Hemorrhagic shock can develop due to severe bleeding, such as after major trauma, postpartum or gastrointestinal bleeding. At least two peripheral intravenous routes with large-bore catheters are recommended to reverse hemorrhagic shock, and such functional intravenous routes are essential for the proper management of other concurrent diseases as well. Conditions during helicopter transportation are different from those seen in-hospital, and the primary concerns are to maintain aseptic conditions, protect patient’s privacy, and prevent infection risk, especially during pandemics, such as the ongoing COVID-19. Herein, I describe two recent experiences of improper management during helicopter transport due to intravenous line malfunction. Subsequently, based on my experience, I suggest the use of multiple intravenous routes or preemptive central catheterization in patients requiring helicopter transportation.

Accidental guide wire migration and late percutaneous externalization after central venous catheterization

A 70-year-old man was admitted to the emergency department with recent spontaneous externalization of a metallic device from his right inner thigh. He had been experiencing mild local pain for 2 weeks and had a recent hospitalization due to cardiogenic hemodynamic instability, requiring a central venous catheter placement in his right internal jugular vein 3 months earlier. Doppler ultrasound confirmed the intravascular foreign body hypothesis as a guidewire was identified inside the right femoral vein, associated with femoropopliteal venous thrombosis. The guidewire was successfully removed percutaneously through simple manual traction guided by radioscopy. The patient was discharged the following day on oral anticoagulation with rivaroxaban. On outpatient follow-up 4 weeks post discharge, he had no complaints in the right lower limb except for slight swelling. Central venous catheterization is a common invasive procedure that, although unquestionably safe and well stablished in medical practice, can lead to serious complications when performed without proper technique.

Covid-19 and a lost guidewire: A misty tale of misery!

Central venous catheterization (CVC) is a routine procedure in patients admitted in Intensive Care Units (ICU) worldwide. Most commonly, seldinger technique is being practiced irrespective of the site of insertion. Though considered very safe, guide wire related complications have been reported in the literature and incidence has increased in the COVID era where intensivists have to work in personal protective equipment (PPE). We are reporting about a patient of severe COVID-19, admitted in ICU. His right femoral venous catheterization was done to start vasopressors. The guide wire accidentally slipped inside the femoral vein during the procedure. It was immediately detected and managed with the assistance of interventional radiologist under fluoroscopic guidance. Complications like misplacement of guide wire can be catastrophic during CVC. We have discussed the measures that can prevent or reduce such complications while working in PPE in COVID ICUs.

Fun and Games: Designing a Gamified Central Venous Catheterization Training Simulator

Gamification, or adding elements of games to training systems, has the potential to increase learner engagement and information retention. However, the use of gamification has yet to be explored in Central Venous Catheterization (CVC) trainers which teach a commonly performed medical procedure with high incidence rates. In order to combat these errors, a Dynamic Haptic Robotic Trainer (DHRT) was developed, which focuses on vessel identification and access. A DHRT+ system is currently under development that focuses on whole procedure training (e.g. sterilization and catheter insertion), including a gamified Graphical User Interface. The goal of this paper was to (1) develop a game-like, patient-centered interface to foster personalized learning and (2) understand the perceived utility of gamification for CVC skill development with expert doctors. This paper outlines some of the potential benefits and deficits of the use of gamification in medical trainers that can be used to drive simulation design.
