Brief Summary:
Invasive arterial blood pressure (IABP) monitoring is critical for perioperative and critically ill patients, yet traditional radial artery cannulation near the wrist joint is prone to catheter dysfunction (e.g., kinking, occlusion) due to positional changes, compromising accuracy and patient safety. This trial hypothesizes that modifying the cannulation site to 1.5-2.5 cm proximal to the radial styloid process may enhance catheter stability.
Detailed Description:
Methods and analysis:This is a prospective, parallel-group, randomized, controlled, analyst-blinded trial. A total of 486 participants (231 per group, adjusted for 5% dropout) will be enrolled. Eligible patients (18-75 years, ASA physical status I-III, requiring elective surgery with radial artery cannulation) will be randomized 1:1 to the modified group (1.5-2.5 cm proximal to the radial styloid process) or the conventional group (traditional site). The primary outcome is the incidence of arterial catheter dysfunction (defined by criteria such as blood sampling difficulty, position-dependent waveform, or improved waveform post-square wave test). Secondary outcomes include frequency of catheter dysfunction, damping abnormality rate, first-puncture success rate, number of arterial punctures,arterial cannulation time, complication incidence, and blood pressure measurement differences.
Sample size calculation:This trial utilized a superiority test for sample size calculation. In the 100-case preliminary experiment results, the incidence rate of abnormal arterial catheter function was 30% in the control group and 12% in the modified group. With a predefined superiority margin Δ of -6% (actual observed Δ of -18%), using a type I error rate (α) of 0.025 and statistical power (1-β) of 0.90, statistical calculations determined that 231 participants per group (totaling 462) would be required to detect this difference in a two-sided test. Considering a 5% dropout rate among study subjects, the final planned sample size was adjusted to 486 cases.
