Missing the guidewire: an avoidable complication

Accidental guidewire migration following emergency femoral central venous catheterization

Central venous catheter placement especially the femoral venous catheter is a common practice in critically ill patients. Awareness of potential complications of the guidewire such as guidewire migration is of utmost importance. Though potentially retrievable by a vascular surgeon or interventional radiologist if it occurs, close supervision by a senior person during passage by a junior or inexperienced person, the use of ultrasound before and after placement of catheter, and use of a checklist may help to identify and prevent its occurrence. We present a very rare complication of central venous cannulation of a guidewire migration in our institution. A 12-year-old girl presented to the Paediatric Emergency Unit (PEU) with status epilepticus and aspiration pneumonia and subsequently transferred to the Paediatric Intensive Care Unit (PICU) for ventilatory support. She had accidental guidewire migration to the left internal jugular vein following a right transfemoral central venous catheterization. She underwent successful guidewire retrieval via a right groin incision.

Diagnosis of a missed central line guidewire using critical care ultrasound

Central venous catheterization, though an imperative tool in the management of critically ill patient, is associated with a variety of complications and some of which can be life-threatening. Here, we report an index case in the field of critical care of detecting a missed guidewire primarily using a bedside critical care ultrasound.

Missed Central Venous Guide Wires: A Systematic Analysis of Published Case Reports

OBJECTIVE

The inadvertent loss of an entire guide wire during central venous catheterization can lead to serious patient harm and require additional investigations as well as retrieval procedures. We aimed to analyze globally published reports of lost wires during central venous catheterization to understand its possible etiology, presentation, treatment, and outcomes with an objective of finding solutions to make the procedure safer.

DATA SOURCES

MEDLINE, Scopus, and CINAHL, supplemented by scanning the reference lists of relevant publications.

STUDY SELECTION

All reports describing an inadvertent intravascular loss of a complete guide wire during placement of central venous catheters published up to December 2014 were included. Reports exclusively describing the 1) retrieval method, 2) partially retained guide wires, and 3) entrapped guide wires during withdrawal were excluded.

DATA EXTRACTION

In each instance, we collected data about the method of the missed guide wire detection, the time interval between the procedure and detection, the supplementary investigations performed to confirm the diagnosis, and the risk factors associated with such events as well as the complications, the final outcome, and the wire retrieval methods used.

DATA SYNTHESIS

A systematic analysis of the accessed publications was performed.

CONCLUSIONS

Over the last decade, the number of reported instances of lost guide wires during central venous catheterization has increased rapidly. Unsupervised or improperly supervised insertions of the central catheters by trainees, distractions during insertions, and high workload are the main risk factors. A retained guide wire increases the risk and cost of additional diagnostic and therapeutic interventions, as well as imposing many minor-to-serious life-threatening complications. Continuing education along with simulator-based skill development, vigilant supervision, and a shared workload during out of hours working are likely to prevent such occurrences.
