Bedside Tunneled Hemodialysis Catheter Placement in Patients with COVID-19.

BACKGROUND

COVID-19, the syndrome caused by the novel SARS-CoV2, is associated with high rates of acute kidney injury requiring renal replacement therapy (RRT). It is well known that despite the ease of bedside insertion, the use of nontunneled dialysis catheters (NTDCs) is associated with increased complications compared to tunneled dialysis catheters (TDCs). Our objective was to develop a strategy for TDC placement at the bedside to provide effective dialysis access, conserve resources and decrease personnel exposure at our medical center in an epicenter of the COVID-19 pandemic.

METHODS

A technique for bedside TDC insertion with ultrasound and plain radiographs in the intensive care unit was developed. Test or clinically COVID-19-positive patients requiring RRT were evaluated for bedside emergent NTDC or nonemergent TDC placement. Patients who underwent NTDC placement were monitored for ongoing RRT needs and were converted to TDC at the bedside after 3-5 days. We prospectively collected patient data focusing on complications and mortality.

RESULTS

Of the 36 consultations for dialysis access in COVID-positive patients from March 19 through June 5, 2020, a total of 24 bedside TDCs were placed. Only one patient developed a complication, which was pneumothorax and cardiac tamponade during line placement. In-hospital mortality in the cohort was 63.9%.

CONCLUSIONS

Bedside TDC placement has served to conserve resources, prevent complications with transport to and from the operating room, and decrease personnel exposure during the COVID-19 pandemic. This strategy warrants further consideration and could be used in critically ill patients regardless of COVID status.
