Abstract: Objective To develop a guidance for applying pressure on puncture site after neonatal radial artery sampling (hereinafter referred to as the “guidance”），in order to standardize the procedure，improve the efficiency of compression，and reduce the incidence of complications after radial artery blood sampling. Methods Using literature review，questionnaire investigation and clinical practice，a standardized guidance was established with regard to dressing material，operator’s finger position，pressure intensity and duration. All nurses were trained to apply a “sandwich” point pressure with non-woven pure cotton fabric over puncture site for 5 minutes， based on neonatal systolic blood pressure. To evaluate the effectiveness of the guidance， success rate of hemostasis， degree of palm pulse oxygen desaturation during compression，and bleeding rate of puncture site or subcutaneous tissue were documented. Results After applying the guidance，success rate of hemostasis rose from 69.89% to 97.80%，palm desaturation rate fell from 18.28% to 5.49%，puncture site bleeding rate fell from 35.48% to 6.59%，and subcutaneous hemorrhage rate fell from 33.33% to 9.89%. Conclusion The application of our guidance after neonatal radial artery sampling can effectively achieve hemostasis.
