Original Question

Is this primary or secondary and why?During decompensated heart failure, the use of intravenous inotropes can be necessary. With peripheral venous access, prolonged inotrope infusion can cause phlebitis. However, traditional central venous catheters have possible complications. Peripherally inserted central catheters (PICCs) may be an alternative to traditional catheters. Our objective was to compare the incidence of phlebitis between patients with PICC and those with peripheral venous access catheter indwelling. In a randomized clinical trial, the patients were randomized to PICC and control groups, with 40 patients in each group. The inclusion criteria were hospitalized patients with advanced heart failure, ejection fraction of <0.45, and platelet count of >50,000/mm and current use of continuous intravenous infusion of dobutamine. The patients were randomly assigned to receive a PICC or keep their peripheral venous access. The primary end point was the occurrence of phlebitis. The PICC and control groups included 40 patients each. The median age was 61.5 years; ejection fraction, 0.24; and dobutamine dose, 7.73 µg/(kg min). Phlebitis occurred in 1 patient (2.5%) in the PICC group and in 38 patients (95.0%) in the control group, with an odds ratio of 0.10% (95% confidence interval: 0.01%-1.60%, < 0.001). In conclusion, in severe heart failure patients who received intravenous dobutamine, PICC use reduced the incidence of phlebitis when compared to patients with peripheral v
