6例早产儿桡动脉采血致动脉痉挛的临床诱因分析及系统性护理优化策略OA

Objective:To analyze the key predisposing factors for arterial spasm following radial artery blood collection in preterm in-fants and to develop a systematic nursing optimization strategies.Methods:A retrospective analysis was conducted on the clinical data of six preterm infants who developed arterial spasm following radial artery blood collection.The predisposing factors were analyzed from four dimen-sions:infant-related factors,operator-related factors,environmental and temporal factors,and vascular characteristics.A three-stage nursing strategy was formulated and implemented:precollection,during sampling,and post-spasm.Results:After intervention,arterial spasm in all six cases was relieved within 1 hour.The main predisposing factors were inadequate thermoregulation(body temperature<36.5℃),repeated punc-tures(>2 attempts),and excessive compression pressure(>50 mmHg).Conclusions:For arterial spasm after radial artery blood collection in preterm infants,implementing a full-process management strategy encompassing pre-collection risk warning,precise operation during sam-pling,and immediate response with stepwise intervention after spasm can effectively relieve spasm symptoms,reduce the incidence of arterial spasm,and improve clinical outcomes.This strategy is worthy of clinical promotion.
