The purpose of this study is to evaluate the value of the new technique of non-invasive measurement of Hb in children undergoing a surgical procedure.

Condition Intervention
Non-invasive Hb Measurement in Children
Device: non-invasive measurement of Hb
Procedure: taking blood samples

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Validation of Non-invasive Hb-measurement (SpHb) in Children With the Masimo@ Radical 7

Further study details as provided by Johannes Gutenberg University Mainz:

Primary Outcome Measures:
  • correlation between SpHb(®) and the Hb measured by the ABL800Flex and the Siemens Advia [ Time Frame: one day ]

Secondary Outcome Measures:
  • influence of inhalation anesthetics [ Time Frame: one day ]
    The blood samples are taken from the needle infusion set the child gets for anesthesia. Some children will need an inhalational induction of anesthesia before they can get the needle and the sensor for the SpHb (®) monitoring. So an influence of the application of inhalation anesthetics on the accuracy of the SpHb (®) will be tested.

40 children Taking blood samples and SpHb measurements in awake and spontaneous breathing children.
Device: non-invasive measurement of Hb
Other Name: SpHb (®) by Masimo ® Radical 7
Procedure: taking blood samples
Other Names:
  • blood for BGA (ABL 800)
  • blood for laboratory Hb (Siemens Advia)

Detailed Description:

Several surgical procedures require haemoglobin monitoring due to possible blood loss and the need of blood transfusion. The standard for monitoring hemoglobin (Hb) is the measurement of blood samples. The novel technique of non-invasive continuous measurement of Hb using Pulse CO-Oximetry may allow measuring Hb without obtaining blood samples.

This new technique has not been tested yet in children undergoing anesthesia for elective surgical procedures. In this study the investigators compare the non-invasive Hb measurement with Masimo® technology (SpHb) with the standard Hb measurement using ABL-800 Flex (BGA) and Siemens Advia (labHb, reference method) before the children undergo the surgical procedure.
