Utilizing nasal‐tragus length to estimate optimal endotracheal tube depth in neonates: A prospective randomized control study
Authors' conclusion
Based on the results from the studied sample, NTL +1 cm formula is a better predictor than Weight + 6 cm formula to determine endotracheal tube insertion depth in term Indian neonates.
Study context
- Population
- Full term neonates undergoing surgery
- Participants
- 120 neonates
- Comparison
- NTL + 1 cm vs Weight + 6 cm formula for ETT insertion depth
- Nn = 60
- Wn = 60reference
- Primary endpoint
- Position of the ETT using either weight-based or nasal-tragus length-based formulae
Methodological detailsprospective
- Prospective
Primary result
As reported in the abstract
Distance from carina to ETT tip
P = <.001
Secondary outcomes
Repositioning of ETT (distance from carina <20 mm)
P < 0.05
