Abstract
Acute kidney injury (AKI) is common in liver failure prior to orthotopic liver transplantation (OLT) and may complicate the intraoperative course. We describe the logistics of intraoperative continuous renal replacement therapy (CRRT) during OLT and the associated clinical outcomes. We performed a retrospective review of adult patients (age > 18 years) receiving intraoperative CRRT during OLT at the University of Alberta Hospital between January 1, 1996 and December 31, 2005. Demographic, detailed clinical, and perioperative data, physiologic and laboratory measures, details of renal replacement therapy (RRT) provided, and data on renal recovery and survival were ascertained. Of 636 OLTs, 41 (6.4%) received intraoperative CRRT. The most common indications for OLT in these patients were hepatitis C (34.2%) and alcoholic (29.3%) cirrhosis. The median [interquartile range (IQR)] Model for End-Stage Liver Disease score was 38 (31-43), and 90.2% were classified as Child-Pugh class C. Preoperatively, 70% were in the intensive care unit, 58.5% were mechanically ventilated, and 48.7% required vasopressor support. The median (IQR) duration of intraoperative CRRT was 258 (189-390) minutes, representing 57% of the total operative time. Filter circuit clotting occurred in 40% but was not associated with a shorter CRRT duration (P = 0.41). No other complications were described. CRRT allowed an even or negative intraoperative fluid balance in 92.7%. CRRT was continued in 78% after OLT for a median (IQR) of 5 (3-11) days. Of these, 24 (75%) were transitioned to intermittent hemodialysis for a median (IQR) of 15 (4-39) days. Survival was 97.6% at 1 month and 75.6% at 1 year. Renal recovery to RRT independence occurred in 100% of survivors by 1 year; however, the mean (standard deviation) estimated glomerular filtration rate (eGFR) was 54.7 (19.1) mL/minute/m(2), with 62.1% having an eGFR < 60 mL/minute/m(2). In conclusion, our data suggest that intraoperative CRRT during OLT is achievable and safe. Intraoperative CRRT may be a valuable adjuvant therapy for those with preoperative AKI. Additional investigations are warranted.

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
