Peripheral Intravenous Catheters (PIV) are extensively used in sick neonates for administration of medicines and nutrition. When these PIVs are used on intermittent basis, they are flushed with saline in order to keep the hub of the catheter free from blood. Presence of blood in the hub of the catheter can be potentially dangerous as it could facilitate infection.
The aim of this study was to find the magnitude of blood contamination of PIV catheter hub after routine flushing.
We measured the volume of 24 g PIV by filling it with saline and thereby measuring its volume. The PIVs which were in situ for at least 6 hours and removed were used for this study. These catheters were flushed with 0.2 ml of saline and the RBC count was calculated.
A total of 94 PIVs were studied, out of which 84% showed blood tinged residual flush and 15% of them had visible blood clot. All (100%) of the catheter studied showed RBCs on microscopic examination. The median RBC count was 36960/cu mm and the interquartile range was 10000 - 113920/cu mm. The highest RBC count was 2080000/cu mm.
Blood contamination of the small bore PIVs after flushing is universal in neonates.
外周静脉导管(PIV)在患病新生儿中广泛用于给药和营养支持。当间歇性使用这些PIV时,会用生理盐水冲洗以保持导管接头无血。导管接头处有血液可能具有潜在危险,因为这可能会促进感染。
本研究的目的是确定常规冲洗后PIV导管接头的血液污染程度。
我们通过用生理盐水填充24G PIV来测量其体积。本研究使用原位至少6小时并已拔除的PIV。这些导管用0.2ml生理盐水冲洗,并计算红细胞计数。
共研究了94根PIV,其中84%的冲洗残余液有血色,15%有可见血凝块。所有(100%)研究的导管在显微镜检查中均显示有红细胞。红细胞计数中位数为36960/立方毫米,四分位间距为10000 - 113920/立方毫米。最高红细胞计数为2080000/立方毫米。
新生儿冲洗后小口径PIV的血液污染很普遍。
