Abstract

Background: Blood pressure (BP) is a basic hemodynamic monitoring index that is a core
vital sign used as a basis for diagnosis, management and treatment of patients postoperatively.
Measurement of blood pressure can be accomplished invasively or non-invasively. Accurate
blood pressure measurement is critical in which the inaccuracies may delay treatment of serious
conditions. Several studies have indicated a significant relation between invasive and noninvasive
arterial blood pressure measurement. Therefore, the aim of this study is to investigate correlation
between invasive and noninvasive arterial blood pressure monitoring in pediatric cardiac surgical
patients in Intensive Care Unit at Children Hospital, Mansoura University. Material and
Methods: A comparative research design was used to carry outconvenient sample the research on
fifty pediatric cardiac surgical patients in Intensive Care Unit at Children Hospital, Mansoura
University. Two tools were used to collect data about correlation between invasive and
noninvasive arterial blood pressure measurements. Results: the findings showed a significant
correlation between invasive and noninvasive arterial blood pressure pre and postoperatively in
pediatric cardiac surgical patients. Six equations were inferred from our results to calculate
invasive arterial blood pressure from noninvasive ABP (systolic, diastolic and mean ABP pre and
postoperatively). Conclusion: Invasive arterial blood pressure can be calculated by inference
from noninvasive arterial blood pressure using the calculated equations pre and postoperatively.
Recommendation: Further research studies are required to measure correlation between invasive
and noninvasive arterial blood pressure with different sites as brachial and femoral arteries as well
as replication of this study on a large probability sample.
