Key Issue One:

Disinfection time of the infusion connector

Clinically, there are many types of infusion joints, including split septum connectors, mechanical valve connectors, positive displacement connectors, negative displacement connectors, neutral displacement connectors, etc. How to determine the disinfection time of so many kinds of infusion connectors?

The most direct way to determine the disinfection time of the infusion connector is to check the instruction manual, if the workload is heavy and you don’t have time to check, or the instruction manual is not specified, you need to refer to the "Expert Consensus on Clinical Venous Catheter Maintenance and Operation" published by the Chinese Nursing Association in 2019, that is, the needleless connector should be wiped vigorously for 5-15 seconds with a disinfectant cotton pad in multiple directions and to be dried, and the disinfection and drying time is determined according to the design of the needleless connector and the type of the disinfectant.

Key Issue Two:

Disinfection method of infusion connectors

During disinfection, use the thumb and index finger of the left hand to pinch the end of the joint, and the thumb and index finger of the right hand to take the disinfectant tool (75% alcohol pads), completely wrap the connecting surface of the connector, wipe it forcefully, repeatedly, and in multiple directions, rotate the connecting surface of the joint 180 degrees clockwise and then rotate 180 degrees counterclockwise to return to the original point.

According to China's 2014 "Intravenous Treatment Nursing Technical Operation Specifications" given a clear point: before infusion and injection through the infusion connector (or interface), disinfectant should be used to wipe the cross-section and outer diameter (that is, the threaded port) of various connectors (or interfaces) in multiple directions.

Key Issue Three:

Disinfection tool for infusion connectors

The use of PVP swabs/alcohol pads has some contact surfaces (especially the threaded mouth) that cannot be disinfected thoroughly. During the operation, the joint was disinfected with a fluorescent agent instead of iodine, and then it was found that the fluorescent agent at the thread mouth was unevenly distributed by fluorescent lamp irradiation.

In 2019, the "Expert Consensus on Clinical Intravenous Catheter Maintenance Operation" published by the Chinese Nursing Association clearly pointed out that the use of disinfecting caps containing alcohol or isopropyl alcohol can reduce the risk of central catheter-associated bloodstream infection (CLABSI)
