A Study of Stimulant Medications Infusion Through Midline Catheters Based on Real-world Data

Midline catheters were inserted by hospital nurses in each center, and patients with MC catheters were included in order, and baseline data of patients were extracted from medical records, including patients' age, gender, education level, body mass index, occupation, admission diagnosis, thrombosis history, major surgery trauma history, chronic medical history, catheterization history and related examination indicators. At the same time, researchers authorized by the principal investigators of each center and uniformly trained researchers will collect data and record the puncture situation during catheterization: including catheter, puncture method, puncture location, puncture arm, puncture site, punctured blood vessel and vascular diameter, number of puncture needles, catheter brand, catheter model, catheter insertion length, catheter exposed length, catheter tip position; During the catheter indwelling period, the catheter function and complications were collected until extubation, and the reasons for extubation, transcatheter blood collection, and vascular intima were recorded, and the patient's transcatheter drug information was extracted from the medical record.
