摘要:

Assist-control ventilation was compared to intermittent mandatory ventilation (IMV) for respiratory support of 35 patients without known respiratory disease, who had undergone coronary bypass surgery. Spontaneous respiratory rates and minute ventilation did not differ significantly between the two groups. Blood gas samples obtained during the assist-control mode had a significantly lower PaCO2and higher pH than blood gases measured during high-rate IMV. There were six cases of severe alkalemia during assist-control ventilation, all respiratory in origin. These were attributable to the higher respiratory-rate settings and the extra respirator-delivered tidal volumes when spontaneous rates were higher than the set rates. IMV was associated with fewer ventilator-induced acid-base changes.

摘要:

Twenty-seven surgical patients who developed post-extubation hypoxemia unresponsive to routine respiratory therapy (incentive spirometry and chest physical therapy) received continuous positive airway pressure (CPAP) delivered through a mask at an inspired oxygen fraction (FIO2) of 0.45. All patients responded with an increased PaO2and achieved a PaO2/FIO2ratio of at least 300 with a mean CPAP of 8.3 ± 2.8 cm H2O. Mean duration of treatment was 23 ± 14 h. Two (7%) patients required reintubation, one for control of excessive secretions and the other for persistentPseudomonaspneumonia. Mask CPAP was an effective treatment for postextubation hypoxemia in this group of surgical patients.

摘要:

Chylous leakage from the thoracic duct into the pleural space may occur after any type of thoracic surgery; however, there are few reports of this condition after coronary artery bypass grafting. A case of chylothorax after combined coronary bypass and mitral valve replacement is reported to illustrate a discussion of its pathologic basis, diagnosis and management.

摘要:

Nonocclusive mesenteric infarction is a potentially lethal complication that may follow successful resuscitation of cardiopulmonary arrest. This case demonstrates that the manifestations may be delayed and that urgent surgical intervention may be lifesaving despite the precarious status of these patients. Vigilance for several days is mandatory.

摘要:

Delayed-onset pulmonary edema complicating severe diabetic ketoacidosis was observed twice in one patient. Hemodynamic measurements during the second episode showed normal transmural pulmonary capillary wedge pressure, suggesting an alteration in alveolocapillary permeability. Hyperventilation and acidosis may underlie this alteration. Vigorous fluid therapy, while decreasing oncotic pressure, may also contribute to the pulmonary edema. The two episodes in one patient suggest that pulmonary microvascular diabetic angiopathy may predispose some diabetics with severe ketoacidosis to increased-permeability pulmonary edema.
