title: Pneumothorax of late onset after chest stabbings.
abstract: Pneumothorax is a well known immediate complication of penetrating chest injuries, but its late occurrence is not widely recognized. In a retrospective study of 56 patients who sustained stab wounds of the chest, 6 (10 per cent) developed pneumothorax between twelve hours and three days after injury. Combined thoraco-abdominal stab wounds were present in three patients and surgical emphysema was also apparent in three other patients. We conclude that pneumothorax of late onset may be commoner than has been suspected and this emphasizes the need for observation in hospital for 48 h and for serial radiography of the erect chest to detect this dangerous complication.
