Reason analysis and nursing strategy of coronarospasm after percutaneous coronary intervention

Abstract

Objective To explore the reason and nursing strategy of coronarospasm after percutaneous coronary intervention(PCI). Methods A total of 1 064 patients with coronary heart disease, who were given PCI from January 2012 to June 2013 in our department, were randomly divided into groups A, B, C and D, 266 cases for each. All patients were successfully punctured radial artery and given corresponding medicines through tubes in radial artery sheaths. Patients in the group A was given 200 μg nitroglycerin and 1 mg verapamil, patients of the group B with 200 μg nitroglycerin, patients with 1 mg verapamil in the group C, while patients in the group D served as control group and was given 5-10 ml normal saline. The incidences of patients with spasms in each group were compared. Results Radial artery spasm were 0.75% in the group A, 1.5% in the group B, 4.4% in the group C, and 5.64% in the control group, and the result of control group had statistical significance with that of group A and B (χ2=6.386 8, 6.604 3; P<0.05). A total of 32 cases with coronarospasm after PCI all had been rescued. Conclusions Application of medicines for preventing radial and coronary artery spasms and careful nursing can effectively decrease the rate of artery spasms.
