Abstract

Objectives: To compare non-invasive (Doppler and Oscillometric) and invasive (indwelling umbilical arterial catheter, UAC) methods for measuring blood pressure in extremely preterm neonates.

Methods: Neonates < 28 weeks gestation were recruited if UAC was inserted as part of their clinical care. Blood pressure measured 4-6 hourly by Oscillometric and Doppler methods was compared with invasive method (10-15 readings/baby).

Results: 438 blood pressure recordings were taken from 11 neonates. Compared to invasive method, non-invasive methods underestimated (P = 0.630) and overestimated (P = 0.431 for > 10% overestimation, P = 0.960 for > 20% overestimation) blood pressure. The frequency of blood pressure being within 10% of UAC reading was higher with the Oscillometric method compared to Doppler (41% vs 17%).

Conclusions: Compared to invasive arterial recording, non-invasive methods underestimated as well as overestimated blood pressure in extremely preterm neonates. Oscillometric methods are more reliable compared to Doppler methods.

极早产新生儿的无创血压测量：不同方法的比较分析。

目的：比较无创（多普勒和示波法）和有创（脐动脉留置导管，UAC）测量极早产儿血压的方法。结果：对11例新生儿进行438次血压记录。与有创方法相比，无创方法低估血压（P = 0.630）和高估血压（>高估10% P = 0.431, >高估20% P = 0.960）。与多普勒法相比，振荡法血压在UAC读数10%以内的频率更高（41% vs 17%）。结论：与有创动脉记录法相比，无创动脉记录法对极早产儿血压有低估和高估的作用。振荡法比多普勒法更可靠。

期刊介绍： The general objective of Indian Pediatrics is "To promote the science and practice of Pediatrics." An important guiding principle has been the simultaneous need to inform, educate and entertain the target audience. The specific key objectives are: -To publish original, relevant, well researched peer reviewed articles on issues related to child health. -To provide continuing education to support informed clinical decisions and research. -To foster responsible and balanced debate on controversial issues that affect child health, including non-clinical areas such as medical education, ethics, law, environment and economics. -To achieve the highest level of ethical medical journalism and to produce a publication that is timely, credible and enjoyable to read.
