Comparison of monitoring performance of bioreactance versus esophageal Doppler in pediatric patients
BACKGROUND AND AIMS: Cardiac output (CO) monitoring and goal-directed therapy during major abdominal surgery is currently used to decrease postoperative complications. However, few monitors are currently available for pediatric patients. Nicom(®) is a noninvasive CO monitoring technique based on the...

description | BACKGROUND AND AIMS: Cardiac output (CO) monitoring and goal-directed therapy during major abdominal surgery is currently used to decrease postoperative complications. However, few monitors are currently available for pediatric patients. Nicom(®) is a noninvasive CO monitoring technique based on the bioreactance principle (analysis of frequency variations of a delivered oscillating current traversing the thoracic cavity). Nicom(®) may be a useful monitor for pediatric patients. SUBJECTS AND METHODS: Pediatric patients undergoing major abdominal surgery under general anesthesia with cardiac monitoring by transesophageal Doppler (TED) were included. Continuously recorded hemodynamic variables obtained from both bioreactance and TED were compared. Data were analyzed using the Bland–Altman method. RESULTS: A total of 113 pairs of cardiac index (CI) measurments from 16 patients were analyzed. Mean age was 59 months (95% CI: 42-75) and mean weight was 17 kg (95% CI: 15–20). In the overall population, Bland–Altman analysis revealed a bias of 0.4 L/min/m(2), precision of 1.55 L/min/m(2), limits of agreement of −1.1 to 1.9 L/min/m(2) and a percentage error of 47%. For children weighing >15 kg, results were: Bias 0.51 L/min/m(2), precision 1.17 L/min/m(2), limits of agreement −0.64 to 1.66 L/min/m(2) and percentage error 34%. CONCLUSION: Simultaneous CI estimations made by bioreactance and TED showed high percentage of errors that is not clinically acceptable. Bioreactance cannot be considered suitable for monitoring pediatric patients. |
