Background

Patients with respiratory failure who require prone positioning are not considered good candidates for PD due to the concerns for increased intra-abdominal pressure, impaired diaphragmatic movement, and leaking of peritoneal fluid. We addressed the COVID-related AKI (CRAKI) surge for renal replacement therapy (RRT) by initiating an acute PD program at Bellevue Hospital including prone patients.

Methods

All patients were in the ICU with COVID related hypoxic respiratory failure and acute kidney injury (AKI). 6/35 patients who received PD were treated for 16 hours per day in the prone position to improve oxygenation. The mean age was 54.6. The average BMI was 35.5. Patients were on mechanical ventilation 12-33 days. 3/6 patients were on CVVH however, switched to PD due to clotting. Patients were on PD for an average of 9.3 days. All PD catheters were placed at the bedside using an open cut down technique. PD was started the same day using manual exchanges. Dwell volume was gradually increased to 2 L. Exchanges were performed q1h while supine and q2h while prone, a total of 4-6 exchanges/day. The PD team coordinated timing with the prone team and ICU nurses to allow the continuation of the PD treatment. Patients were monitored clinically for abdominal distention and changes in respiratory mechanics.

Results

All 6 patients remained on PD for the duration of the hospitalization. There were no incidences of bowel injury, hemorrhage, exit-site infections, or peritonitis. None of the patients had any catheter malfunction. Leaking was addressed with temporarily reducing the dwell volume. Patients experienced slow draining which was due to kinking of the tubing during prone positioning. All patients were able to continue receiving PD without interruptions. Either no change or improvement in ABG and ventilator settings was noted after prone positioning and PD.

Conclusion

Due to COVID related surge, we saw a significant number of patients in the ICU with severe acute respiratory failure requiring prone positioning who also developed AKI requiring RRT. We were able to successfully provide acute PD in ventilator-dependent prone patients suffering from CRAKI. This required a team effort and some modifications in the conventional PD prescription.
