Based on the previous research, this study intends to explore the outcome of trans-MC infusion of stimulant drugs when the MC tip is located in the subclavian vein/chest wall segment axillary vein, especially to analyze the relationship between drug dose, infusion days and catheter-related complications, so as to provide a basis for the clinical application of MC infusion stimulant drugs, provide evidence for the revision of infusion practice guidelines, and ensure the safety of patients' infusion. Reduce the occurrence of adverse events, provide a basis for further expanding the clinical application scope of MC, reduce unnecessary peripherally inserted central venous catheters (PICC) and central venous catheters (CVC) and other central venous catheters, and reduce medical costs.
Age greater than or equal to 18 years old.
In patients with conventional indwelling single-chamber three-way valve MC, the catheter tip is located in the axillary vein or subclavian vein of the chest wall segment.
Those who have been placed with a central venous catheter during MC insertion.
Vulnerable groups, including people with mental illness, cognitive impairment, critically ill patients, minors, pregnant women, illiterates, etc.
