ABSTRACT
PURPOSE: This study was designed to review the clinical outcome of infants who underwent tracheostomy in the neonatal intensive care unit (NICU) of a single center in Korea during 16 years. METHODS: We retrospectively reviewed medical records of 33 patients who underwent tracheostomy in NICU of Samsung Medical Center between January, 1997 and December, 2013. We collected data on timing, indications, clinical outcomes, and complications of tracheostomy in the study patients. We also compared these variables with those in another single center study (study A) recently showing the outcome of infants who underwent tracheostomy in a NICU of USA during 10 years. RESULTS: The median gestational age and birth weight of the study patients were 35 weeks, and 3,200 g, respectively. Gestational age of the study patients was greater than that of study A (35 weeks vs. 27 weeks). The most common indication for tracheostomy was airway disease (69.7%) in our study. Bronchopulmonary dysplasia (9%) was less frequent indication for tracheostomy in our study when compared with in the study A (41%). Granuloma formation was the most common complication of tracheostomy (48%) and decannulation was accomplished in nine patients (27.3%). Although the mortality rate was 12.1%, no patient died from tracheostomy-related complications. CONCLUSION: Main causes of tracheostomy in our NICU are airway problems and neuromuscular diseases rather than bronchopulmonary dysplasia itself. For better clarification of clinical courses and outcomes related to tracheostomy performed in NICU in Korea, further study in a larger population will be needed.
