Practice Pattern of Hemodialysis Vascular Access in Maiduguri, Nigeria

Initial Experience with Central Venous Line Insertion in a Tertiary Health Institution in Nigeria

Background:

Central venous catheterization is an uncommon procedure in most hospitals in the West African subregion. This article presents our initial experience with central line insertion.

Materials and Methods:

Catheter sizes ranged from 5 fr for children and 7 fr for adult for intravenous therapy, while size 7 fr polyurethane catheters were used for children requiring hemodialysis and sizes 12–14 fr silicone catheters for adolescents and adults requiring hemodialysis'. Data were collected prospectively using a structured pro forma over a 2-year period (June 2010–May 2012) and analyzed with SPSS 15.

Results:

A total of 77 lines were inserted four as tunneled lines and 73 as nontunneled lines. Forty-seven (61.0%) patients were male, 30 (39.0%) were female, with age range of 1–80 years. The success rate was 97.4%. The overall complication rate was 16.9%.

Conclusion:

Our initial experience with the use of central venous lines, was marked by a high success rate, few manageable complications and no mortality over the study period. Majority of insertions were done by the bedside under local anesthesia lending credence to the assertion that it is a relatively safe procedure that can be done by any adequately trained doctor and should, therefore, be encouraged in our hospitals.

[Emergency vascular access conversion to native arterio veinous fistula: a prospective study of 37 hemodialysis patients in Rwanda]

Chronic hemodialysis in Rwanda is relatively recent and most of patients are treated with catheters.

SUMMARY

Thirty-seven patients who require chronic hemodialysis with catheters were evaluated during a 3-years period in order to facilitate the creation of a permanent vascular access for hemodialysis (AVF). Patient selection were made during a multi-disciplinary consultation. The sex-ratio was 1.5 and the main cause of the nephropathy was arterial hypertension.

RESULTS

Thirty-one patients benefited from the creation of an arterioveinous fistula. All of the interventions were performed using local or loco-regional anesthesia. Sixty percent of these AVF were radio-cephalic, 35.4% were humero-cephalic. Sixty-four percent of the operations were performed on ambulatory patients, with a primary function for 90% of them.

CONCLUSION

This work proves the feasibility of the creation of AVF in Rwanda, thus allowing to preclude the various complications that arise with the prolonged use of a catheter. This experience was made possible by the pooling of the resources of 4 of Rwanda's leading hospitals. In an early future, the development of vascular surgery will assure the permanence of this care.
