Objective: Pneumothorax (PTX) is a potentially life-threatening condition that affects neonates, with an incidence of 0.05 to 2%. Its management includes conservative treatment, chest tube (CT) drainage, and needle aspiration (NA). Aims were to evaluate the incidence of PTX in a 10-hospital perinatal network, its clinical characteristics and risk factors, and to compare the different treatment options.
Study design: All neonates diagnosed with PTX and hospitalized in the network were included in this retrospective observational trial over a period of 30 months. Primary outcome was the incidence of PTX. Secondary outcomes were the treatment modality, the length of stay (LOS), and the number of chest X-rays.
Results: Among the 173 neonates included, the overall incidence of PTX was 0.56 per 100 births with a large range among the hospitals (0.12-1.24). Thirty-nine percent of pneumothoraces were treated conservatively, 41% by CT drainage, 13% by NA, and 7% by combined treatment. Failure rate was higher for NA (37%) than for CT drainage (9%). However, the number of X-rays was lower for patients treated by NA, with a median of 6 (interquartile range [IQR] 4-6.25), than by CT drainage, with a median of 9 (IQR 7-12). LOS was shorter for NA than for CT drainage, with a median of 2 (IQR 1-4.25) and 6 days (IQR 3-15), respectively. Complications, including apnea and urinary retention, occurred in 28% of patients managed with CT drainage, whereas none was observed with NA.
Conclusion: High variability of PTX incidence was observed among the hospitals within the network, but these values correspond to the literature. NA showed to reduce the number of X-rays, the LOS, and complications compared with CT drainage, but it carries a high failure rate. This study helped provide a new decisional management algorithm to harmonize and improve PTX treatment within our network.
Key points: · Neonatal pneumothorax (PTX) is a frequent pathology with a high incidence requiring urgent management.. · We report a large variability of PTX incidence between different hospitals of the same network.. · Needle aspiration carries higher failure rate, shorter hospital stay duration without complications reported..
