OBJECTIVES:
To determine the statistical agreement between hematocrit and platelet counts obtained
via peripheral venous catheters and venous puncture. It also aims to compare the success rate of obtaining
samples via PVC and the hemolysis rate between different gauges of IV catheter.
DESIGN:
Prospective Cross-sectional Study.
PARTICIPANTS:
Clinically stable patients admitted for dengue aged 1 to 18 years old and are eligible
to be enrolled in the study. Twenty-two patients were enrolled and completed the study.
INTERVENTION:
Paired samples of venous blood collection using venipuncture and PVC on the
contralateral arm was done during daily serial CBC monitoring. Hematocrit and platelet values between
the two methods were analyzed using Bland-Altman Analysis.
MAIN OUTCOME MEASURES:
Statistical agreement of platelet and hematocrit levels obtained using
PVC and Venipuncture.
RESULTS:
We had 22 patients and a total of 67 paired samples. Out of the 67 samples submitted, two
samples each from PVC (2.9%) and venipuncture (2.9%) were clotted. There was100% success rate in
both methods at the first attempt of collection. None on the samples had hemolysis. On the average,
hematocrit measurements from venipuncture are increased by 1.17 (units) compared to PVC, while
platelet measurements from PVC are increased by 4.83 (units) compared to venipuncture. There is no
significant difference in both platelet count and hematocrit between the two methods, demonstrating
agreement between the two methods.
CONCLUSIONS
There is statistical agreement between samples drawn from PVC and venipuncture in
terms of hematocrit and platelet counts in dengue pediatric patients. Success rate and hemolysis rates
between the two methods are the same. PVC is an acceptable alternative to venipuncture.
