Long Peripheral Intravenous Catheter Insertion Site and Catheter-related Complications in Antimicrobial Therapy

Long Peripheral Intravenous Catheter Insertion Site and Catheter-related Complications in Antimicrobial Therapy: a Randomized Controlled Trial

This study applies long PIVCs to patients undergoing antimicrobial therapy, and compares the effects of different placement sites, aiming to provide a reference basis for patients undergoing antimicrobial treatment to select the optimal placement site, thus reducing complications, prolonging catheter retention time, and alleviating the patient's pain.

This study investigates the use of long PIVCs in patients undergoing antimicrobial therapy, and compares the effects of different insertion sites. The aim is to provide evidence-based recommendations for the optimal placement site for long PIVCs in antimicrobial treatment, with the goals of reducing complications, prolonging catheter retention time, and alleviating patient discomfort.

Inclusion Criteria:

• ① estimated time of intravenous infusion ≥1 week; ② age: ≥18 years; ③ antimicrobial therapy was only used for treatment during hospitalization, with a pH value of 5-9 and osmotic pressure < 900 mOsm/L; and ④ patients were conscious and able to communicate normally; ⑤ the catheter-to-vessel ratio is less than 45%.

Exclusion Criteria:

• ① a history of radiotherapy, thrombosis, and trauma at the catheterization site and ② plans to discharge with a catheter during the study duration.
