Abstract
With limited resources, cardiac surgery is frequently cancelled due to lack of ICU beds. Immediate postoperative extubation (UFT) is performed in our hospital setting. The aim of the present study is to report patients undergoing off-pump aortocoronary bypass grafting (OPCABG) with immediate extubation and no ICU stay. Eighty-five patients undergoing OPCABG were included. UFT analgesia consisted of high thoracic epidural analgesia (n=65), or PCA morphine (n=20). Discharge criteria from PACU to cardiac ward were: alert, cooperative patient, respiratory rate <25/min, PaO(2)>80 mmHg and PaCO(2)<45 mmHg, temperature >36 degrees C, hemodynamic stability, no bleeding, no ischemia, and sufficient analgesia. More males (71/14) were included. Mean age was 63.4 years, NYHA class III, ejection fraction 59.4. Three grafts were performed in 119 min. Patients were extubated 12+/-2 min after closure. After 428 min in PACU, four patients did not meet ward criteria; three bradycardia requiring pacing, one elevated CK-MB. Two patients returned to the ICU, one for hypertension, and one for hypovolemia. Cardiac complications were: atrial fibrillation (29%), MI=2, bradycardia=3. During the same period, 304 OR-extubated patients spent 21+/-6 h in the ICU. The cost from leaving the OR until the patient reached the cardiac ward was 1265$ for ICU bypass patients vs. 6405$ for ICU patients, the difference representing 5140$ per patient. ICU bypass after OPCABG is safe. By avoiding ICU, this protocol reduces costs, improves resource utilization and may reduce OR cancellation due to ICU bed shortages.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
