By means of cw-Doppler-ultrasonics pulsation curves of anterior cerebral arteries were recorded before, during and after a necessary capillary blood sampling in 12 premature newborns. Patients were stable and needed no oxygenation. Blood pressure and transcutaneous oxygen saturation have been recorded simultaneously. The most important hemorheological parameters were within normal range. Immediately following irritation pulsatility indices increased, partly diastolic reflux phenomena could be observed. Finishing irritation values went back to starting position very fast. It is supposed such strong changes of cerebral vascular resistance could be the reason of cerebrovascular damages in non sedated premature newborn babies.
通过连续波多普勒超声，在12例早产儿进行必要的毛细血管采血之前、期间和之后记录大脑前动脉的搏动曲线。患儿病情稳定，无需吸氧。同时记录血压和经皮血氧饱和度。最重要的血液流变学参数在正常范围内。刺激后搏动指数立即增加，部分可观察到舒张期反流现象。刺激结束后数值很快回到起始位置。据推测，脑血管阻力的如此强烈变化可能是非镇静早产儿脑血管损伤的原因。
