Objective: The role of the Associate Program Director (APD) within surgical education is not clearly defined or regulated by the Accreditation Council for Graduate Medical Education, often leading to variations in the responsibilities among institutions. Required credentials are not specified and compensation and protected time are not regulated resulting in large discrepancies among institutions. APDs are brought into the fold of surgical education to parcel out the escalating responsibilities of program director (PD).

- The study compares two methods of measuring circulating blood volume (BV) in critically ill patients: ultrasound dilution and radioisotope dilution.
- The research involved 50 patients with central venous catheters and arterial lines using both measurement techniques, revealing that the larger ultrasound injectate (60-mL) correlated better with the radioisotope method than the smaller (30-mL) injectate.
- Despite the improved correlation with the 60-mL method, there remains a significant variability in the measurements, suggesting the need for further development before ultrasound can reliably estimate BV in surgical patients.
