Lower friction resistance between catheter and RA wall may reduce RAS upon insertion, manipulation, and withdrawal of the catheter. The aim of this study w as to investigate whether the use of a hydrophilic-coated (HC) catheter, which has lower friction coefficient, could reduce the incidence of RAS compared with a non-hydrophilic-coated (NHC) catheter. Methods: A total 250 patients attempt ed diagnostic CAG using 5-French catheters via the TRA between September 2000 a nd April 2002. Two hundred thirty-four (93.6%) patients who achieved successfu l coronary cannulation were selected for the study. NHC catheters were used in 1 49 patients (63.7%), and HC catheters were used in 85 patients (36.3%). We com pared the incidence of RAS between NHC and HC catheters. Results: RAS occurred i n 17 (7%) patients totally. RAS was less likely to occur in HC group (one patie nt, 1%) than in the NHC group (16 patients, 11%, P=0.007). Conclusions: We con clude that the use of HC catheters can reduce RAS upon insertion, manipulation, and withdrawal of the catheter compared with NHC catheters.展开更多
