Purse-string suture to prevent bleeding after tunneled dialysis catheter insertion.

Area of Science:

• Nephrology
• Vascular Surgery
• Interventional Radiology

Background:

• Postprocedural bleeding is a common complication following tunneled dialysis catheter (TDC) insertion.
• Minimizing bleeding is crucial for patient comfort and preventing further complications.

Purpose of the Study:

• To evaluate the efficacy of purse-string sutures at the tunnel exit site in reducing postprocedural bleeding after TDC insertion.

Main Methods:

• A retrospective study compared 51 patients without purse-string sutures (control) to 50 patients with purse-string sutures (experimental) at the TDC tunnel exit site.
• Outcomes assessed included postprocedural bleeding noted in charts, plasma hemoglobin levels, and need for blood transfusions within 5 days.

Main Results:

• A significantly lower incidence of postprocedural bleeding was observed in the experimental group (6%) compared to the control group (25.4%, P = .0124).
• No patients in the experimental group required prolonged compression, while 6% in the control group did.
• Mean hemoglobin decrease was not significantly different between groups, nor was the rate of red blood cell transfusion.

Conclusions:

• Routine placement of purse-string sutures at the tunnel exit site during TDC insertion is an effective method to significantly decrease postprocedural bleeding.
• This minor technical modification can substantially reduce bleeding complications associated with TDC placement.
