Abstract
Objective
Point of care ultrasound (POCUS) use is increasing in pediatrics and has been demonstrated to be superior in identifying central catheter tip location in neonatal intensive care units. However, limited data exist regarding cardiorespiratory changes secondary to POCUS in neonates.
Study design
A prospective observational equivalence study was performed on 50 POCUS assessments of central catheter tip location in 46 patients ≥23 weeks gestation. Heart rate (HR), respiratory rate (RR), and percent oxygen saturation (SpO2) levels were collected before and after POCUS. Limits of equivalence were set in advance.
Result
Equivalence was demonstrated in HR, RR, and SpO2 before and after POCUS. HR decreased by 3.24 beats per minute (90% CI: −5.36, −1.14). RR increased by 0.71 breath/min (90% CI: −1.84, +3.27). SpO2 increased by 0.54 percentage points (90% CI: −0.23, +1.31).
Conclusion
Identifying central catheter tip location using POCUS in neonates appears safe without affecting cardiorespiratory stability.
