Brief Summary

The goal if this study is to employ the CardioQ-Esophageal Aortic Doppler probe to define fluid responders from non-responders among infants undergoing cranial vault reconstruction for craniosynostosis. After defining these two groups in this single arm prospective trial, the investigators will compare the predictive utility of non-invasive devices such as the CipherOx-Compensatory Reserve Index (CipherOx-CRI) and Inferior Vena Cava Collapsibility Index (IVC CI) to currently employed indices (heart rate, systolic blood pressure, urine output and pulse pressure variability) to gauge the need for additional fluid and ongoing resuscitation. If the CipherOx-CRI or IVC CI proved to be as predictive or better at predicting fluid responders, the investigators hope to replace invasive arterial lines with non-invasive tools to guide resuscitation.

Conditions

Hypovolemia; Craniosynostoses

Outcome Measures

Primary Outcomes (1)

• Utility of Compensatory Reserve Index (CRI) Which Ranges From 0-1 in Order to Predict Fluid Responders From Non-responders

  Using a delta peak aortic velocity threshold of 10% (measured from CardioQ-EDM) before and after a bolus to define fluid responders (=/\>10%) from non-responders (\<10%), we will determine the performance of pre-bolus CRI reading which is an index between 0 and 1 (0=poor reserve and 1=excellent reserve) in order to predict fluid responders from non-responders. Measurements will be recorded three times with one minute between measurements and then averaged. Vital signs analyzed included heart rate, systolic blood pressure, mean arterial pressure, shock index (heart rate/systolic blood pressure), pulse pressure variability, and end-tidal carbon dioxide level. Infants were also monitored with a Compensatory Reserve Index (CRI) monitor, which provides a continuous, individual-specific, beat-to-beat estimate of central volume status, from normovolemia (CRI=1) to decompensation (CRI=0). Each variable's performance was compared using area under the receiver operator curves (AUC).

After defining fluid responders from non-responders in this single arm prospective trial, we will compare the predictive utility of non-invasive devices such as the CipherOx-CRI and IVC CI to currently employed indices (heart rate, systolic blood pressure, urine output and pulse pressure variability) to gauge the need for additional fluid and ongoing resuscitation.

Device: CardioQ-EDM and CipherOx-CRI

Interventions

CardioQ-EDM and CipherOx-CRI DEVICE

A CardioQ-EDM probe will be placed on the day of surgery after induction of general anesthesia. The anesthesiologist will inform the investigator of plans to provide a fluid or blood bolus per clinical judgement in addition to the protocolized 10 ml/kg bolus provided after induction. While the anesthesiologist is preparing to administer volume expansion, a co-investigator will collect pre-fluid bolus data. Measurements will be recorded for data analysis at the completion of the trial. Additionally, a CipherOx-CRI probe will be placed on the patient's index finger (recorded data will be interpreted post hoc) and a bedside ultrasound will be performed by either the principal investigator (PI) or one of two co-investigators to measure the IVC CI. Ultrasound cine-loops will be recorded, and CI will be calculated post-hoc. Data will be recorded on the Data Collection Form for each fluid bolus administered. The PI and co-investigators will manage all aspects of investigational devices.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: NA
• Masking: NONE
• Masking Details: As these devices are experimental in this patient population, anesthesiologists will be blinded to hemodynamic data generated by the CardioQ-EDM, bedside ultrasound, and CipherOx CRI. If data is needed in an emergent setting, the subject will be excluded from analysis. Although recorded measurements from the Cardio-Q EDM monitor will be visible to the study team, IVC measurements will be stored and calculated post-hoc by a co-investigator blinded to whether or not the subject is or is not fluid responsive. Additionally, a trained statistician not involved in data collection will be paid for analysis. It should also be noted at Dr. Steven Moulton is a paid officer of CipherOx but will not be involved in the data collection and analysis.
