Hamburg NNTT Table: Validation Data for Neonatal Nasotracheal Tube Placement

A prospective validation study of the Hamburg Neonatal Naso-Tracheal Tube Table for determining endotracheal tube depth in neonates. The study enrolled 72 neonates (58 preterm, 14 term) in a single tertiary neonatal intensive care unit. Correct tube positioning occurred in 90.3% of cases, with accuracy lower in extremely preterm infants.

Use Cases

• Validate length-based intubation depth guidelines based on the study's 90.3% success rate.
• Analyze intubation accuracy differences between preterm and term infants based on the reported 80.6% vs. 97.6% results.
• Refine neonatal intubation protocols for extremely preterm infants based on the identified need for improvement.
• Compare traditional weight-based formulae to length-based methods using the study's clinical applicability findings.

Strengths

• Prospective validation in a clinical setting with 72 enrolled neonates.
• Specific accuracy results reported: 90.3% overall correct placement.
• Comparative analysis between subgroups: 80.6% accuracy in infants <28 weeks vs. 97.6% in older infants.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a single-centre study, which may limit generalizability.
