1/5. hemopneumothorax in a COPD patient treated with noninvasive positive pressure ventilation: the risk of attendant anticoagulation.Noninvasive positive pressure ventilation (NIPPV) modalities have been proven to be effective in the setting of exacerbations of chronic obstructive pulmonary disease (COPD). Reported complications include pneumothorax, increased work of breathing, gastric distension and air embolism. This case demonstrates that patients with severe COPD on anticoagulant therapy are potentially at risk for the serious complication of combined lung barotrauma and hemorrhage while on acute NIPPV therapy. This is the first reported case of hemopneumothorax complicating NIPPV therapy.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/5. Internal jugular catheterisation. blood reflux is not a reliable sign in patients with thoracic trauma.An internal jugular catheter, which was inserted into a patient with a traumatic haemopneumothorax, accidentally entered the pleural cavity. This was initially undetected because the two signs most frequently used to confirm correct placement, those of blood reflux and fluctuation of central venous pressure with respiration, were positive. A number of precautions are suggested which should be taken when central venous catheters are inserted in patients with thoracic trauma.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
3/5. pneumoperitoneum and pneumoretroperitoneum. Consequences of positive end-expiratory pressure therapy.patients receiving positive end-expiratory pressure (PEEP) therapy should be considered at risk for pneumoperitoneum. In the four patients described, chest roentgenographic demonstration of pulmonary interstitial gas and pneumomediastinum, frequently but not always associated with pneumothorax, preceded the dissection of gas into the abdominal cavity. Neither prompt intubation of the pleural space with reexpansion of the lung in the event of pneumothorax nor decrease in the PEEP applied precluded dissection of gas from the mediastinum into the retroperitoneal and peritoneal spaces. This sequence of roentgenographic events should strongly suggest pneumoretroperitoneum and pneumoperitoneum as a sequela to PEEP therapy rather than a ruptured viscus.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/5. Delayed cardiac tamponade.A case report of cardiac tamponade is described which did not manifest itself until the patient was allowed to breathe spontaneously. Changes in intrapericardial pressure during spontaneous and controlled ventilation are discussed.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
5/5. Traumatic massive air leak treated with prolonged double lumen intubation and high frequency ventilation: case report.A case is presented of unilateral traumatic massive air leak successfully treated with prolonged double-lumen endobronchial intubation and unilateral high frequency intermittent positive pressure ventilation, while the "good" lung was ventilated conventionally. The problems encountered are described and the rationale for this management are discussed.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
