[Acute left heart failure following repair of atrial septal defects. Its treatment by reopening].
Among 716 patients operated on for an ASD, 15 of them, following closure of the defect, developed acute left heart failure requiring partial re-opening. The most prominent anatomical finding in these cases was hypoplasia of the left ventricle. ⋯ Therefore, a marked difference of the stroke work of the left and right ventricle, respectively, appeared to be the essential underlying hemodynamic mechanism. The prognosis has been found to depend mainly on prompt surgical intervention; so in all poor-risk cases continued monitoring of left atrial pressure is indicated for early detection of impending left heart failure.--The high incidence of left heart failure as cause of death after repair of an ASD indicates the importance of this complication.

Comparative StudyEffects of intraoperative PEEP on postoperative arterial oxygenation.
Previous studies have suggested that early postoperative hypozemia may be due to a reduction of functional residual capacity (FRC) during anesthesia and surgery. Positive end-expiratory pressure (PEEP) has been recommended as a means of maintaining FRC and improving arterial oxygenation. ⋯ Patients receiving PEEP maintained the highest mean Pao2 intraoperatively. However, the beneficial effect of intraoperative PEEP was not sustained in the recovery room, where all patients experienced the same degree of arterial hypoxemia.

Adult respiratory distress syndrome in postoperative patients: study of pulmonary pathology in "shock lung" with prophylactic and therapeutic implications.
Lungs of 44 patients who died after postoperative respiratory distress and shock had a significantly higher incidence of atelectasis and thromboembolism than did 31 control patients. However, both lesions were as inconstant in occurrence as all other 15 investigated pulmonary changes. ⋯ While possibly a contributing factor, shock is not the most important cause of the pulmonary lesions in postoperative patients. The term "shock lung" should be eliminated and renewed emphasis should be placed on detection, prevention and treatment of the pathogenic mechanisms involved in each individual case.

The authors present 29 cases of post-operative respiratory complications in abdominal surgery in subjects without any past history of respiratory disorders. They stress the diagnostic value of these cases of acute respiratory failure shown in a third of the cases of surgical complications.

A series of 29 femoropopliteal bypass operations is described. The patients were selected carefully to exclude those with clinical and aortographic evidence of aorto-iliac disease. ⋯ There was a highly significant difference in the result of the operation between patients with a pulsatility index of 4 or more in the common femoral artery and patients with a pulsatility index of less than 4. We concluded that calculation of this pulsatility index provides useful additional evidence when selecting patients suitable for a femoropopliteal bypass.
