- Registration Number
- NCT06014099
- Lead Sponsor
- Sir Run Run Shaw Hospital
- Brief Summary
Therefore, in this study, the investigators propose to use a randomized controlled prospective open study on inpatients with difficult blood collection, by comparing the effects of the application of two types of peripheral venous catheters for blood collection via LPC and MC, with a view to improving the success rate of blood collection in difficult peripheral venous blood collection, and providing a theoretical basis for the later application of long peripheral venous catheters and midline catheters; and providing a basis for optimizing the experience of venous blood collection by nurses.
- Detailed Description
Using block randomization, patients were randomized in 1:1:1 blocks into experimental arm 1(Long peripheral venous catheter), experimental arm 2(midline catheter), and control (short peripheral venous catheter) with a block length of 6. Patients have a total of 27 blocks, import data into SPSS23, randomly group by SPSS, generate random numbers, and group according to the size of random numbers in each unit group, the largest in the group is assigned to the experimental group 1, the middle of the group is assigned to the experimental group 2, and the smallest in the group is assigned to the control group. The experimental group1 used the LPC for blood collection, the experimental group 2 used the MC for blood collection,and the control group used the Short PIVC for blood collection.

Long peripheral venous catheters Long peripheral venous catheters for blood collection In the test 1 group, blood was collected using LPC. short peripheral venous catheters SPCs for blood collection In the control group,blood was collected using SPC.
- Primary Outcome Measures
Name Time Method Total success rate of blood collection during catheter indwelling,an average of 2 weeks Number of patients with successful intravenous blood collection as a proportion of the number of cases in this group
Success rate of first blood collection during catheter indwelling,an average of 2 weeks Number of successful initial venous blood collection cases as a percentage of the total number of cases in this group
- Secondary Outcome Measures
Name Time Method Number of days for catheters to linger during catheter indwelling,an average of 2 weeks The number of days between catheter insertion and catheter removal
Catheter-related complication rate during catheter indwelling,an average of 2 weeks The proportion of patients with complications as a proportion of the total number of cases
