Abstract

Objective: We aimed to present the active management and outcomes of infants born at 22 weeks of gestation.

Study design: This retrospective observational study presented the resuscitation methods, management during hospitalization, and outcomes of 29 infants born at 22 weeks of gestation who were actively resuscitated and admitted to our center during 2013-2020.

Results: The survival rate was 82.8% (24/29). Tracheal intubation was performed in all patients, and surfactant was administered for 27 (93.1%). Conventional mechanical ventilation was introduced in 27 (93.1%), and this was changed to high-frequency oscillatory ventilation in more than half by day 4. Surgical treatments of patent ductus arteriosus, necrotizing enterocolitis, and retinopathy of prematurity were required in 4 (13.7%), 3 (10.3%), and 15 (51.7%) patients, respectively. No patient required a tracheostomy or ventriculoperitoneal shunt.

Conclusions: The overall survival rate and survival rate without morbidities were high among infants born at 22 weeks of gestation.
