Physiologic changes associated with endotracheal intubation in preterm infants.

Abstract

Physiologic changes associated with endotracheal intubation were examined in 10 preterm infants. Laryngoscopy was associated with apnea and minor abnormalities in cardiac rhythm in 2 infants. Three infants had nasal airflow recordings which demonstrated obstructed breaths during laryngoscopy. Systolic blood pressure (BP) increased 47% when the trachea was intubated, whereas heart rate and transcutaneous oxygen tension (PtcO2) decreased. Because endotracheal intubation is a physiologically stressful procedure, personnel who intubate preterm infants must be skilled and experienced to minimize the duration of laryngoscopy and the number of intubation attempts.
