[Diagnosis and prognosis of spontaneous pneumomediastinum in eighteen children].

Abstract

OBJECTIVE:

To analyze the diagnosis, treatment and prognosis of spontaneous pneumomediastinum (SPM) in children.

METHOD:

A retrospective analysis of the clinical data of 18 children diagnosed with SPM in Yuying Children's Hospital Affiliated to Wenzhou Medical University from December 2007 to February 2013 was performed. Information of the sequelae and recurrence of SPM was obtained by telephone follow-up. SPM was diagnosed according to Versteegh's standard. SPM cases due to mechanical ventilation, trauma, inhaled foreign body or as a result of the underlying disease were not included. Also cases of secondary pneumothorax pneumomediastinum and neonatal mediastinal emphysema were excluded.

RESULT:

Fifteen of 18 cases were boys and 3 were girls, the range of age was from 9 to 17 years. Predisposing factors included sport activities, severe cough or without a known cause. Clinical manifestations included chest pain, chest tightness, dyspnea, neck pain, back pain, foreign body sensation or pain on swallowing, throat pain of swelling. Chest CT of 18 cases showed pneumomediastinum, 8 cases displayed varied degrees of air in neck, chest; 18 cases of SPM responded well to bed rest, oxygen, antitussive and anti-infection treatment. Fifteen cases received chest CT or X-ray inspection after therapy, showing that the pneumomediastinum disappeared or significantly absorbed, 3 cases improved in clinical symptom. Among 18 patients, telephone follow-up of 14 were successful and 4 cases were lost. An average follow-up time was (24 ± 17) months. None of the cases had any serious consequences, and recurrence happened in one case.

CONCLUSION:

Children's spontaneous pneumomediastinum is a benign disease. When a child has chest pain or chest tightness, SPM should be considered after excluding the common diseases. SPM can be diagnosed in association with clinical feature and chest CT examination. Patients respond well to conservative therapy and most of them had no severe sequelae.
