[PO.1 index as a predictor of successful extubation in patients after posterior fossa tumors removal].
The goal of the study was to assess the clinical value of PO. 1 index for prognosis of successful weaning from mechanical ventilation in patients after posterior fossa tumors removal. 25 patients were involved in the study. 15 patients were successfully extubated in 24 hours time after surgery and 10 patients had prolonged mechanical ventilation. PO. 1 indexes in both groups were assessed and compared. Successfully extubated patients had higher PO. 1 index. PO. 1 index > 2 indicated that extubation would be successful with 93.3% sensitivity and 87.5% specificity. In successfully extubated patients the elevation of PO. 1 index during spontaneous breathing test was noted In the second group there was no such an effect. Elevation of PO. 1 index during spontaneous breathing test predicted successful extubation with 100% sensitivity and 80% specificity.
