Insights
New wireless sensors accurately monitored vital signs in pediatric patients undergoing surgery for congenital heart defects. This technology offers a feasible alternative to traditional monitoring methods.
Area of Science:
- Biomedical Engineering
- Pediatric Cardiology
- Medical Devices
Background:
- Congenital heart defects necessitate surgical intervention in over 40,000 children annually.
- Continuous vital sign monitoring is critical for pediatric surgical patient care.
Purpose of the Study:
- To evaluate the real-world feasibility of novel wireless sensors for vital sign monitoring.
- To compare the performance of experimental wireless sensors against standard monitoring equipment in pediatric patients with congenital heart defects.
Main Methods:
- A prospective, single-arm observational study enrolled 13 pediatric patients undergoing cardiac surgery.
- Vital signs were monitored using both standard equipment and an FDA-cleared wireless sensor device (ANNE®).
- Data analysis included Bland-Altman plots to compare heart rate and respiratory rate measurements.
Main Results:
- The study involved 13 pediatric patients (4 months to 16 years) with congenital heart defects.
- Over 1000 hours of vital sign data were collected, generating more than 60,000 data points.
- Wireless sensors demonstrated comparable performance to standard monitoring equipment.
Conclusions:
- Novel wireless, flexible sensors are a viable option for monitoring pediatric patients with congenital heart defects.
- This technology shows comparable accuracy to existing monitoring systems, enhancing patient care possibilities.
Introduction:
More than 40,000 children undergo surgical interventions annually for the treatment of congenital heart defects. Intraoperative and postoperative vital sign monitoring is a cornerstone of pediatric care.
Methods:
A single-arm prospective observational study was performed. Pediatric patients undergoing a procedure with a planned admission to the Cardiac Intensive Care Unit at Lurie Children's Hospital (Chicago, IL) were eligible for enrollment. Participant vital signs were monitored using standard equipment and an FDA-cleared experimental device (ANNE® ) consisting of a wireless patch positioned at the suprasternal notch and index finger or foot. The primary goal of the study was to assess real-world feasibility of wireless sensors in pediatric patients with congenital cardiac defects.
Results:
A total of 13 patients were enrolled, ranging in age from 4 months to 16 years with a median age of 4 years. Overall, 54% (n = 7) were female and the most common anomaly in the cohort was an atrial septal defect (n = 6). The mean admission length was 3 days (range 2-6), resulting in more than 1000 h of vital sign monitoring (⟩60,000 data points). Bland-Altman plots were generated for heart rate and respiratory rate to assess beat-to-beast differences between the standard equipment and the experimental sensors.
Conclusions:
Novel, wireless, flexible sensors demonstrated comparable performance to standard monitoring equipment in a cohort of pediatric patients with congenital cardiac heart defects undergoing surgery.
