venous indwelling needles usage

The application of venous indwelling needles is a better method for clinical infusion. On the one hand, it can alleviate the pain caused by repeated puncture of scalp needles in infants and young children who can be used for long-term infusion. On the other hand, it also reduces the workload of clinical nurses.
The intravenous indwelling needle is easy to operate and is suitable for puncture in any part, and relieves the pain of repeated puncture of the patient, reduces the workload of the nursing staff, and is popular in the clinic. However, the retention time has been controversial. The health administrative department, the hospital sense and the indwelling needle manufacturers all advocate that the retention time should not exceed 3-5 days.
Indwelling time perspective
The venous indwelling needle has a short indwelling time, and the elders have 27 days. Zhao Xingting recommended to retain 96h through animal experiments. Qi Hong believes that it is completely feasible to retain for 7 days as long as the tube is kept relatively sterile and the surrounding skin is clean, as long as no blockage or leakage occurs. Li Xiaoyan and other 50 patients with trocar indwelling were observed, with an average of 8-9 days, of which up to 27 days, no infection occurred. The GARLAND study believes that peripheral Teflon catheters can be safely retained for up to 144 hours with proper monitoring. Huang Liyun et al believe that they can remain in the blood vessels for 5-7 days. Xiaoxiang Gui and other people think that it is the best time to stay for about 15 days. If it is an adult, and the indwelling site is proper, the local remains good, and no inflammatory reaction can prolong the indwelling time.
