OBJECTIVES: The aim of this study was to test the hypothesis that moderate procedural sedation can reduce the incidence of radial artery spasm. BACKGROUND: Transradial access for left heart catheterization and percutaneous coronary intervention is increasingly used for emergent and elective procedures, in lieu of the femoral approach. However, increased rates of access site crossover have been reported, with radial artery spasm being a major contributor to this effect. METHODS:Patients undergoing elective transradial percutaneous coronary intervention were prospectively randomized to receive fentanyl and midazolam during the procedure or no treatment (control subjects). The primary endpoint was angiographically confirmed radial artery spasm. Patient discomfort was quantified with a visual analogue scale. RESULTS:Two thousand thirteen patients (age 64.5 ± 8.4 years) were randomized. Spasm occurred in 2.6% of the treatment group versus 8.3% of control subjects (p < 0.001; odds ratio [OR]: 0.29). The number needed to treat to avoid 1 case of spasm was 18 (95% confidence interval [CI]: 12.9 to 26.6). The access site crossover rate was 34% lower in the treatment group: 9.9% versus 15.0% (OR: 0.62; 95% CI: 0.48 to 0.82). Patient discomfort visual analogue scale score was 18.8 ± 12.5 in the treatment group versus 27.4 ± 17.4 in control subjects (p < 0.001). No significant differences were observed in the 30-day rate of death or repeat hospital stay for any cause: 4.6% versus 4.5% (OR: 1.02; 95% CI: 0.67 to 1.56). CONCLUSIONS: Routine administration of relatively low doses of an opioid/benzodiazepine combination during transradial interventional procedures is associated with a substantial reduction in the rate of spasm, the need for access site crossover, and the procedure-related level of patient discomfort.
