Basic Research on Nursing Aseptic Technique for Hospital Infection Control

为控制医院感染，护理工作后洗手是护理人员最重要的技能之一。然而，目前还不清楚什么样的污染物和多少粘附在护士的手，由每个护理。此外，我们不知道这些污染物是否可以通过洗手来消除。为了解某医院重症监护病房护理人员每次护理后手部污染的实际情况及洗手后手部污染的消除情况，本研究对20例护理人员进行了调查。采用接触平板法，分别于护理前、护理后及洗手后，对护理人员的手部进行采样。护理人员每次护理后用肥皂和流动水洗手约30秒，用纸巾擦干，当护理人员独立护理患者时，如身体清洁和气管内吸引护理，洗手可完全清除手上的污染物。在医疗援助的情况下，少量但大量的手部污染物没有被消除。据推测，这些未消除的污染物是由于一个小的应变，在一个助理护理以及护理技术问题。

To control hospital infections, hand washing after nursing practices is one of the most important techniques for nurses. It is, however, unclear what kinds of and how many contaminants are adhered on nurses'hand by each nursing care. Further more, we do not know whether these contaminants can be eliminated by hand washing. The purpose of this study is to know the actual condition of hand's contamination and its elimination by hand washing after each nursing care at critical care wards in a hospital.This year, twenty nursing care cases were examined. They are body cleaning cares, endotracheal suction cares and body position change cares, so on. Samples were taken from nurses'hand before and after nursing care for patients and after hand washing by a contaict plate method. Nurses'hands after each care were washed by soap and running water about 30 seconds, and dried by a papertowel.When nurses independently care for patients, such as body cleaning and endotracheal suction cares, contaminants on hands were completely eliminated by hand washing. In the case of medical assistance, small but significant amounts of hand's contaminants were not eliminated. It is assumed that these unelimination of contaminants are due to a small strain in an assistant care as well as technical problems in nursing cares.
