Abstract: Objective: To investigate the effects of optimization postural training on the coordination compliance and postoperative complications risk in patients scheduled by thyroid surgery.Methods: Eighty patients scheduled by thyroid surgery were randomly divided into the control group and observation group(40 cases each group).The control group and observation group were treated with conventional postural training and optimization postural training,respectively.The coordination compliance,healthy knowledge,postoperative SF-36 score,postoperative complications and nursing satisfaction between two groups were compared.Results: The coordination compliance,healthy knowledge,postoperative SF-36 score and nursing satisfaction in observation group were higher than those in control group(P<0.05 to P<0.01).The incidences of the postoperative headache,nausea and vomiting and waist back pain in observation group were lower than those in control group(P<0.05 to P<0.01).Conclusions: The optimization postural training in nursing the patients scheduled by thyroid surgery can effectively improve the coordination compliance,healthy knowledge,quality of life and nurse-patient relationship,reduce the postoperative complications risk,and the clinical effects of which are better than those of conventional postural training.
