The anterior to midaxillary line between the 4th or 5th intercostal space (Buelau position) is safe for the use of thoracostomy tubes in preterm and term infants.

Objectives: Thoracostomy tubes are widely used in neonatology. Complications occurred significantly more frequently in infants, especially neonates, than in adults. Principally, the access is the modified Buelau position which takes place in the anterior axillary line at the 4th or 5th intercostal space above the margin of the ribs.
