【摘要】 目的探讨光子双源CT颅脑灌注成像中的护理技术。方法对47例行脑灌注成像患者的相关资料进行了回顾性的分析。扫描前仔细询问病史及相关药物过敏史,并进行碘过敏试验;选择静脉注射部位并评估患者血管条件;检查结束后注意观察患者情况,对患者出现的不适状况进行对症处理。结果 50例患者检查前碘过敏试验均呈阴性。49例患者一次完成灌注检查;1例因对比剂外渗、重新选择注射静脉后完成灌注检查;其中,30例患者无任何不适感;18例出现一过性的热感;1例头晕、恶心、面部轻微潮红,经心理护理,症状消失;1例出现荨麻疹,静注地塞米松10mg,皮疹渐消退。1例对比剂渗入皮下,用50%硫酸镁冷湿敷后吸收消失;无1例出现严重过敏反应。结论严格的护理流程是CT脑灌注检查成功和提高图像质量的重要保证。更多还原

【Abstract】 Objective To explore the nursing of brain CT perfusion imaging with dual-source CT. Methods In this retrospective study,50 patients with suspected or known cerebral diseases who underwent low-dose brain CT perfusion were analyzed.Before the CT scanning,medical history and allergic history taking carefully,and iodine allergy test were performed. We chose the proper injection vein and assess the vein; after the CT scanning,we observed the adverse effects,and provided in-time treatment. Results The iodine allergy tests were negative in all 50 patients. 49 patients performed the CT perfusion at one-stage,and1 patient finished the CT perfusion twice because of the exosmose of contrast medium. No discomfort was found in 30 patients,transitory sense of warm in 18 patients,dizzy,sick and paroxysmal facial flush in 1 patient. The symptoms disappeared after psychological care. Urticaria in 1 patient,the symptoms disappeared after injecting of 10 ml Dexamethasone. Exosmose of contrast medium in 1 patient,the symptoms disappeared after cold compressing by magnesium sulfate. No serious adverse event had been associated with the contrast medium. Conclusion The strict nursing is essential for the success and imaging quality of brain CT perfusion with dual-source CT.更多还原
