Abstract

LOPEZ GONZALEZ, Antonio; FERNANDEZ RIVERA, Constantino; DIAZ RODRIGUEZ, Lorena  and  ORNOSA AGRA, Carmen. Impact of the needle gauge in the quality of hemodialysis. Enferm Nefrol [online]. 2015, vol.18, n.2, pp.118-122. ISSN 2255-3517.  http://dx.doi.org/10.4321/S2254-28842015000200007.

Introduction: Blood flow is a factor closely related to the dialysis efficacy. High blood flows are associated with better quality of dialysis and therefore the use of large needle gauge is recommended. Objective: Analyze the effect of gauge needles in the puncture of arteriovenous fistulas and examine its impact on the perception of pain and bleeding time after his retirement at the end of the session. Methods: A cross-sectional study was conducted. Data were collected using 15G and 16G needles to puncture the arteriovenous fistula. The variables are pump speed, effective flow, Kt/V, venous pressure, session length, systolic blood pressure, diastolic blood pressure, recirculation, degree of pain and clotting time. In addition, we have collected the variables age, sex and location of the vascular access. Results: In 52 analyzed fistulas found statistically significant differences in the use of different needle gauges in the variables effective blood flow, venous pressure and duration of the session. Discussion: The results of our study allow us to recommend the use of 15G needles because they will allow us to use high blood flows without generating morbidity for the patient, allowing reaching the recommended dose of dialysis treatment in less time.

Keywords : needle gauge; hemodialysis; dialysis efficiency.
