摘要

Peripheral intravenous catheterization (PIVC) is a common invasive procedure in hospital setting. When it fails, patients may endure discomfort and experience delays in treatment and laboratory testing. This study aimed to assess whether a pressure-controlled tourniquet (PCT) influences the success rate of PIVC in hospitalized patients. This parallel group randomized controlled clinical trial enrolled 148 eligible patients, who were randomly allocated to either the PCT or the elastic tourniquet (ET) group. The primary outcome was the First Attempt Insertion Success (FAIS) rate. Data were analyzed with SPSS 27.0.1.0. The FAIS rate for PIVC was 91.7% in the PCT group and 82.9% in the ET group, but this difference was not statistically significant (p = 0.11). Comparison of time to PIVC insertion between the two groups showed that the time was significantly (p = 0.003) shorter in the PCT group (26.59 ± 13.08 s) compared to the ET group (32.88 ± 13.89 s). Sex was a significant predictor of catheter placement success, with men being approximately 1.5 times more likely than women to achieve successful placement. A history of comorbid conditions and elevated body mass index were independently associated with a significantly lower likelihood of successful peripheral venous catheter placement (p < 0.001). The PCT significantly improved vein palpability compared to the ET, with success rates of 98.6% and 89.5%, respectively. The use of a PCT during PIVC may improve vein visualization and palpation, potentially enhancing patient comfort and reducing the time required for successful catheter placement. Although no significant difference in initial success rates was observed between the PCT and ET groups, the findings suggest that PCT may offer clinical advantages, particularly when considering patient-specific factors such as sex and pre-existing medical conditions that influence catheterization outcomes.
