Brief pathway to handle temporary HD catheter
This document provides guidance on the use of temporary hemodialysis catheters. It discusses indications for temporary catheters such as acute kidney injury or as a bridge to renal transplantation. Types of temporary catheters and precautions before insertion are outlined. The document also reviews care after insertion, common complications, and how to manage catheter-related bloodstream infections. The overall message is that arteriovenous fistula is preferred for end-stage renal disease patients requiring long-term hemodialysis, but temporary catheters have a role when fistula is not ready or in cases of acute kidney injury.

Selected factors favoringdifferent temporary (non-tunneled) hemodialysis catheter insertion sites Right internal jugular site Critically ill and bed-bound with body mass index >28 Postoperative aortic aneurysm repair Ambulatory patient/mobility required for rehabilitation Femoral sites Critically ill and bed-bound with body mass index <24 Tracheostomy present or planned in near-term Need for long-term hemodialysis access present, highly likely or planned Emergency dialysis required plus inexperienced operator and/or no access to ultrasound Left internal jugular site Contraindications to right internal jugular and femoral sites Subclavian sites Contraindications to internal jugular and femoral sites Right side to be used preferentially
- 11. Some comments duringinsertion • Benefits of US guided insertion in both IJ and femoral access. • Confirmation of guide wire removal. • Sharps management. • Dressing. • Catheter locking (citrate vs heparin, use of local ab & TPA)
- 12. Care after insertion: •Hand hygiene. • Exit site dressing. • Nasal mupirocin 2%. • Replacement of unnecessary catheter. • Instructions to patient. • Preferred time to remove temporary catheter.
- 13. Complications of temporarycatheters:
- 14. Some definitions: • Cathetermechanical dysfunction was defined as inability to achieve blood flow rate of >250 mL/min or high blood pump pressures despite attempts to improve flow such as patient repositioning or reversal of catheter lumen • Definite CRB was defined as fever with temperature >38°C with isolation of identical micro-organism from cultures of blood and catheter tip and no other obvious focus of infection. • Possible CRB was defined as fever with temperature >38°C and no other obvious focus of infection and where the microbiological criteria were insufficient to make a diagnosis of definite CRB. • Exit site infection was defined as the development of cellulitis or purulent discharge at the site of catheter insertion.
- 16. How to dealwith catheter infection? o When suspected CRB (culture, salvage pathway, treatment). o Choice of empirical ab : combination of • Vancomycin plus o Meropenem, imipenem or etrapenem. o Gentamicin o Pipracillin/tazobactam o fluconazole o Confirmed infection (culture, removal, duration of ttt) • Metastatic complications 4-6 ws • Staph. Aureus &MDR bacilli more than 14 ds. • Enterococci 7-14 ds. • Candida 14 ds since last negative culture. • Uncomplicated 7 days only.
- 17. Home message: • AVFis the preferred venous access to ESRD who are expected to have HD unless contraindicated. • When expected to have HD more than 3 ws, cuffed tunneled HD catheter is the preferred. • In AKI, tunneled is better than NTHDC. • Follow bundle for care and maintenance of HD catheter. • Don’t miss the role of nursing and patient.
