Non-invasive BP measurement cannot replace Invasive blood pressure in Pediatric ICU :Study
In an intensive care unit, blood pressure (BP) recording is an integral part of hemodynamic monitoring for quick therapeutic decisions. Though Non-invasive BP (NIBP) monitoring by an oscillatory automated device is a widely accepted and most feasible modality in most clinical settings, Invasive BP(IBP) monitoring after placing an intra-arterial catheter is considered the gold standard as it provides continuous, reliable, and beat to beat monitoring of the BP.
Several studies have compared the accuracy of NIBP to IBP in intensive clinical care settings, there are fewer such studies in the pediatric cardiac critical care setting. Dr Amit Kumar et al conducted a study to compare IBP and NIBP recording in a PICU unit. The findings of this study are published in latest issue of Indian Pediatrics Journal.
In this observational prospective study a total of 45 children aged 1-18 years with intra-arterial lines as per standard management protocol were enrolled. NIBP measurement was done by the oscillatory method and IBP measurement was performed with an appropriately sized arterial catheter inserted into the radial/femoral artery and connected to a disposable pressure transducer.NIBP was measured every 4 hourly and the corresponding IBP reading was recorded. A total of 839 upper limb NIBP measurements, 834 femoral line, and 137 radial line blood pressure readings were analysed.
