VASOSPASMS, BLEEDING, GESTATIONAL HYPERTENSION
Subcutaneous nitroglycerin combined with local anesthetics before cannulation increased the first attempt success rate of radial artery cannulation and decreased the overall number of cannulation attempts in women with gestational hypertension and risks of intra-operative bleeding undergoing cesarean section. It also decreased cannulation times and overall number of vasospasms. It may be useful for those anesthesiologists with less experience in radial artery cannulation.
