Objectives: The objective of study was to find an association between the timing of tracheostomy with duration of mechanical ventilation (MV) and length of stay (LOS) in pediatric intensive care unit (PICU) and hospital.
Methods: The data were collected prospectively from 2000 to 2018 and were analyzed retrospectively. Data included clinical diagnosis, indication, and duration (days) of MV, LOS in PICU and hospital before and after tracheostomy. Patients who did not receive MV or underwent MV for <24 h were excluded. According to the indication of tracheostomy enrolled patients were divided into four groups-airways anomalies (AA), central neurological impairment (CNI), cardiopulmonary insufficiency (CPI), and neuromuscular disorders (NMD). Patients in each group were divided into early (ET) and late tracheostomy (LT) category based on the median (interquartile range interquartile range [IQR]) days of pretracheostomy MV.
Results: Two hundred and fifty six patients were analyzed. The frequency and median [IQR] days of pretracheostomy MV were -AA 54 [7(3,16)], CNI 120 [12(9,16)], CPI 51 [25(16.5,30.5)], and NMD 31[12(8,16.5)]. In AA patients, median (IQR) durations of posttracheostomy MV [2(1,5.2) versus 3.5(2,12); p = 0.032], PICU [7(5,8.2) versus11(7,18); p = 0.004] and hospital [12(9.7,21) versus 21.5(12,28); p = 0.027] stays were lower in ET as compared with LT group. Posttracheostomy MV duration was significantly short in ET patients with CNI and NMD (p < 0.005). The total days of MV, PICU and hospital stay were significantly lower in ET as compared with LT patients in all four groups (p < 0.01).
Conclusion: As compared with LT, ET patient had shorter durations of total MV and PICU and hospital stay.
