The haemodynamic management of preterm infants has evolved over time, supported by epidemiological data, physiologically reasoned and well intentioned, but with little sophistication in the physiological assessment and little evidence to guide drug treatment. Rachel Mullaly and Afif Faisal El Khuffash review the present state of knowledge, highlighting the flaws of using mean blood pressure to guide treatment and describing the range of haemodynamic inferences that can be drawn with more sophisticated echocardiographic investigation. Their article is nicely illustrated and includes a summary of the presently used drugs and their potential effects. They acknowledge the weakness of the evidence supporting the wider range of agents increasingly in use and call for trials that use detailed physiological assessment to determine treatment approaches to take us forward. See page F120 Staphylococcus capitis has generated a lot of anxiety of late among neonatologists, with concerns that …

早产儿的血流动力学管理随着时间的推移而不断发展，得到流行病学数据的支持，具有生理学上的合理性和良好的意图，但生理评估不够复杂，也缺乏指导药物治疗的证据。Rachel Mullaly 和 Afif Faisal El Khuffash 回顾了目前的知识状况，强调了使用平均血压指导治疗的缺陷，并描述了可以通过更复杂的超声心动图检查得出的血流动力学推断范围。他们的文章插图精美，包括目前使用的药物及其潜在影响的摘要。他们承认支持越来越多地使用更广泛的药物的证据存在弱点，并呼吁进行使用详细生理评估的试验来确定推动我们前进的治疗方法。参见第 F120 页 头状葡萄球菌最近引起了新生儿科医生的极大焦虑，他们担心……
