We compared the effects of continuous positive-pressure ventilation (CPPV), using 10 cmH2O positive end-expiratory pressure (PEEP), with intermittent positive-pressure ventilation (IPPV), on pulmonary extravascular water volume (PEWV) and lung function in dogs with pulmonary edema caused by elevated left atrial pressure and decreased colloid osmotic pressure. The PEWV was measured by gravimetric and double-isotope indicator dilution methods. Animals with high (22–33 mmHg), moderately elevated (12–20 mmHg), and normal (3–11 mmHg) left atrial pressures (Pla) were studied. The PEWV by both methods was significantly increased in the high and moderate Pla groups, the former greater than the latter (P less than 0.05). There was no difference in the PEWV between animals receiving CPPV and those receiving IPPV in both the high and moderately elevated Pla groups. However, in animals with high Pla, the Pao2 was significantly better maintained and the inflation pressure required to deliver a tidal volume of 12 ml/kg was significantly less with the use of CPPV than with IPPV. We conclude that in pulmonary edema associated with high Pla, PEEP does not reduce PEWV but does improve pulmonary function.

Hydropneumopericardium is defined as the presence of air and water in the pericardial cavity. Several causes have been postulated which can lead to hydropneumopericardium including trauma, infections secondary to gas-producing bacilli, fistula formation, positive pressure ventilation or even spontaneously without an underlying cause in healthy adults and rarely after pericardiocentesis. We report an uncommon instance of hydropneumopericardium after pericardiocentesis in a 35-year-old man, which developed due to a leaky drainage system. It was immediately drained through the subxiphoid approach under echocardiographic guidance, and the patient was relieved. Hydropneumopericardium is an uncommon but easily diagnosable and avoidable complication of pericardiocentesis. It should be suspected whenever the patient develops increasing dyspnoea following a temporary relief by pericardiocentesis.
