The Effect of Skin Laxity on the PICC

Study Overview
=================
Brief Summary
-----------------
To evaluate the clinical effect of tunneled PICC by comparing the rate of complications of the two groups of patients (tunneled PICC vs conventional PICC).

Detailed Description
-----------------
In this study, tunneled PICC was compared with conventional PICC. Eligible subjects were randomly enrolled into the test group or control group by randomization (1:1), and observed and evaluated the occurrence of complications during and 7 ± 3 days, 30 ± 7 days, 60 ± 10 days, 90 ± 10 days, 120 ± 10 days (if any) after surgery and extubation at the end of treatment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| rate of PICC complications | Including bleeding, subcutaneous congestion, lymphatic exudation, phlebitis (mechanical phlebitis, thrombophlebitis), infection (local infection, tunnel infection, catheter related blood flow infection), thrombus (symptomatic thrombus, asymptomatic thrombus), catheter ectopic, medical adhesive related skin damage, catheter damage and blockage, etc | 120 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| time of PICC insertion | Time from the start of skin disinfection to the end of dressing fixation | 1 hour | 
| Success rate of catheterization | Judgment of successful catheterization: The catheterization is successful and the catheter is placed in an accurate position, that is, the tip of the catheter reaches within 1/3 of the lower part of the superior vena cava or near the junction of the right atrium. | 1 hour | 
| score of operation pain | Wong Banker facial expression scale was used. This method uses 6 facial expressions from smile to cry to express the degree of pain: 0 points for no pain, 1 point for slight pain, 2 points for some pain, 3 points for very pain, 4 points for severe pain, and 5 points for unbearable pain | 1 hour | 
| rate of unplanned extubation | Extubation after abnormal treatment | 120 days | 
| rate of difficulty in decannulation | Probability of failure to pull out PICC due to vasospasm, adhesion with thrombus, wrapping of fibrin sheath, etc | 120 days |
