Usefulness of hydrophilic coating on arterial sheath introducer in transradial coronary intervention.
Radial artery spasm is one of the major problems during transradial coronary intervention (TRI). The sheath introducer with hydrophilic coating may reduce the incidence of spasm and reduce the difficulty in removing it from the radial artery under the situation of spasm artery spasm. After we compared the friction resistance between the sheath introducer with hydrophilic coating and that without coating (nine samples each) in vitro, the sheath introducers with and without hydrophilic coating were randomly used in 37 and 36 patients, respectively, who underwent elective TRI with a 6 Fr introducer sheath. Hydrophilic coating of sheath introducer reduced friction resistance by 70% (P < 0.00001) in in vitro model and facilitated sheath removal after finishing TRI (P = 0.0003). Hydrophilic coating of sheath introducer is useful in TRI.
