Conditions

Endotracheal Intubation

Brief summary

This study was conducted on neonates needing intubation; Group A,: the ETT insertion depth was estimated according to the OHL method. Group B,: the ETT insertion depth was estimated according to the 7-8-9 method.

Interventions

ETT was inserted and the depth was estimated by either OHL method or 7-8-9 method

Inclusion criteria

* • Full term and preterm neonates who were admitted to NICU and needing endotracheal intubation for invasive mechanical ventilation or administration of surfactant. * Delivery room intubations were not included as infants are not routinely weighed prior to resuscitation at our hospital. However, infants intubated in the delivery room who were subsequently intubated in the NICU were eligible for inclusion in our study.

Exclusion criteria

\- 1. Major upper or lower airway anomalies. 2. Infants with craniofacial, vertebral anomalies. 3. Significant congenital anomalies including cardiac, abdominal or respiratory. 4\. Neonates those whose parents declined consent were excluded from the study.

Design outcomes

Primary

Secondary

MeasureTime frame
the occurrence of pulmonary air leaks during the first 24 hours after intubation, accidental extubation and duration of ventilation.28 days
