Three-Part Question:
In [a haemodynamically stable patient following penetrating chest wall injury and fluid resuscitation with two litres of normal saline, does the presence of a pneumopericardium on Chest Xray] merit [urgent surgical intervention/exploration] to [reduce clinical course, adverse events, morbidity and mortality]
Clinical Scenario:
An 18-year-old male presents after having been stabbed with a 9inch screwdriver 1cm below the left nipple. On arrival he is tachycardic at 125 bpm with a blood pressure of 110/75. This settles with two litres of normal saline to a pulse rate of 85 bpm and a blood pressure of 129/82. He is fully alert. His chest X-ray reveals the presence of a pneumopericardium. He has no other injuries.
Search Strategy:
Medline 1966 to June 2001 using the OVID interface.
Search Details:

AND (exp cardiac tamponade/ or exp heart injuries/ or exp thoracic injuries/ or exp wounds, penetrating/ or exp wounds, stab/ or "penetrating chest trauma". mp.) AND (exp pneumopericardium/ or "pneumopericardium". mp) AND (exp "wounds and injuries"/ or "wounds. mp)
Outcome:
A literature search found 21 papers relating to this topic. Of these only 4 were found to be relevant. There was only one series which followed the results of 23 patients who were electively managed in the presence of a non tensioned pneumopericardium. There were also 3 isolated case reports relating to the management of a non-tension pneumopericardium.

Author Commentary:
Posttraumatic pneumopericardium is rare. However its presence is likely to be associated with an underlying cardiac abnormality. The studies published to date are mainly of how to manage a pneumopericardium once it has tensioned. All the cases described above, had relatively stable patients who nonetheless required stringent monitoring, with the availability of surgeons on hand to perform a thoracotomy had this proved necessary. These facilities may not be available to the majority of UK based district general hospitals.

Bottom Line:
A pneumopericardium in a haemodynamically stable individual may be managed conservatively. However stringent monitoring and the ready availability of a surgeon capable of performing a thoracotomy are required. For the district general hospital therefore consideration needs to be given to possibly transferring these patients to a more appropriate definitive care facility.
