Objective To summarize the clinical application of parenteral nutrition (PN) in Fuwai Hospital. Methods The clinical applications of PN in 132 critically ill patients undergoing cardiac surgery in our hospital were retrospectively investigated and analyzed. Results The application of PN in Fuwai hospital was basically appropriate and standardized. Energy supply in PN formulation was reasonably low, but still met the energy needs of patients in the fasting period. The nutritional composition and energy/nitrogen ratio in the formulation were basically rational. However, problems including the lack of double energy in partial formulation, low proportion of glucose-supplied energy due to low glucose-lipid ratio, and insufficient supply of insulin still existed. One (0.76%)patient was discharged according to his own decision; 22 ( 16.67% ) patients died, which were not directly associated with PN; and the other 109 (82.58%) patients were cured and discharged. Conclusion Application of PN for critically ill patients undergoing cardiac surgery must strictly follow the operation indications and rationally select nutritional components and proportions to ensure its safety and effectiveness.

The tralning system for orthopedic surgeon in Britaln is mature and complete. After completing education in medical college, medical students receive a 2-year base tralning (FY1, FY2), which focus on learning and consolidating basic medical knowledge and clinical skill, followed by a 6-year specialist tralning, which subdivides into tralning of ankle and foot, hand, should and elbow, hip, knee, spine, and pediatric surgery, provided by several district hospital (Peripheral hospitals). Students are required to return to teaching center for review, ward inspection, case discussion at regular inter-vals. Compared with the specialist tralning system based on the hospital staffs in chi-na, the role ofsocial workersin British during the period of tralning makes better mobility of tralnee among medical institutions and medical treatments, which makes the tralning more comprehensive and professional. In addition, there is no consistent system for examination and admittance of specialist, and awareness of specialist tralning among medical institutions and doctors is weak. Therefore, it should be done to form a single tralning system and unify the tralning specification and assessment standard.
