Objective:To explore the application effect of Plato theory-based risk control management in the in-hospital safe transport of elderly patients in post-anesthesia care unit(PACU).Methods:160 elderly patients who underwent PACU resuscitation and were transported in the backyard were selected as the research subjects.According to different transportation management methods,the patients were divided into a conventional group and a Pareto group,with 80 patients in each group.The routine group was treated with implement routine transportation management,and the Plato group was treated with risk control transfer management based on Plato's theory.The pre-transport indicators[Bispectral index(BIS)value,modified Aldrete score,saturation of arterial oxygen(SpO2),partial pressure of end-tidal carbon dioxide(PET CO2),mean arterial pressure(MAP)],priority risk values during anesthesia recovery,transport conditions(transport preparation time,transport duration and transfer delay rate),adverse events during transport and patients'satisfaction with management measures were compared between the two groups.Results:The BIS,modified Aldrete score and SpO2 in the Plato group at the time of transferring from PACU were higher than those in the conventional group while the PETCO2 and MAP were lower than those in the conventional group(P＜0.05).The risk values scores,transport preparation time,transport time and transfer delay rate were lower than those in the conventional group,and patients'satisfaction with management was higher than that in the conventional group(P＜0.05).Conclusion:Plato theory-based risk control management can reduce the risk values and transport time of intra-hospital transport of elderly patients in PACU,and it is helpful to reduce the adverse events during transport and strengthen the safety of transport,and it has high patient satisfaction.
