Child psychiatric consultants perform psychiatric assessment and liaison among various clinical services. Execution of these familiar roles for pediatric liver transplantation recipients exposes unfamiliar and difficult bioethical problems. Administrative problems arise if the recipient's suitability is too narrowly evaluated. Assessment may be time-limited. The intensive care unit environment and the VIP characteristics of child transplantation patients may distort observations and constrain opportunities for preventive preoperative psychologic management. Unnecessary psychiatric complications may ensue, which imperil the transplantation surgery. The primary caretakers may have an extraordinary emotional investment, so liaison is pressured. Three cases are presented to illustrate these points. Medical ethical perspectives and the limitations of medical training to prepare physicians to perceive them are indicated. That these limitations also affect the psychiatrist is acknowledged, and a clinical research approach is suggested.
