A thorough history and clinical examination is usually all that is required to make the diagnosis of a normal variant. They also help to exclude pathological conditions that may present in a similar fashion. Radiological and other investigations are not routinely required in children with normal variants of the lower limb except to exclude pathological conditions. Shoe inserts, orthoses and physical therapy are not to be encouraged as they provide no benefit. In the majority of cases the natural history is one of spontaneous resolution of the deformity. Surgery may, however, be required in a small number of patients greater than eight years in whom severe in or out-toeing is present. Parental education and reassurance is an important part of the treatment and must be re-emphasized.展开更多

Three groups of patients were separately given by general anesthesia, epidural anesthesia and combined spinal and epidural anesthesia for operations;The variations of adrenocorticotrophic hormone (ACTH), Cortisol (Cor),β-endorphin (β-EP), Angiotensin-Ⅱ(Ang-Ⅱ), heart rate (HR) and blood pressure (SBP, DBP) on patients in three groups before anesthesia (T0), during skin incision (T1), after skin incision (T2) and extubation after operation (T3) were compared and analyzed.Results:During T1, T2, ACTH, Cor,β-EP and Ang-Ⅱlevels in 3 groups of patients were significantly higher than those during T0;SBP and DBP were significantly lower than that during T0;HR during T2 was significantly lower than that during T0;During T3, every index in 3 groups were recovered to levels close to that during T0;During T1, T2, ACTH, Cor,β-EP, Ang-Ⅱlevels in group B and C were significantly lower than that in group A. And levels in C was lower than that in B;SBP and DBP in group B and C were significantly higher than A. No HR statistical significance appeared between each group.Conclusions: During clinical anesthesia, we should choose suitable anesthesia method combined with actual situations of patients. Combined spinal and epidural anesthesia had a slight influence on hemodynamics of elder orthopedics patients during operation, and it could effectively alleviate stress reaction during operation.展开更多

The patients were randomly divided into two groups. The patients were divided into control group and observation group, with 38 cases in each group.The patients in the control group chose routine monitoring and nursing, and the patients in the observation group chose routine monitoring and added risk early warning mechanism.After the end of nursing work, the incidence of accidents and the total effective rate of treatment were compared between the two groups.Results after the end of nursing work, the accident rates of patients in the control group and the observation group were 18.34% and 2.63% respectively. There was significant difference between the two groups (P < 0.05);The total effective rates of patients in the control group and the observation group were 86.84% and 97.37% respectively. There was significant difference between the two groups (P < 0.05).Conclusion the application of risk early warning mechanism can effectively improve the incidence of accidents in orthopaedic perioperative nursing, and can significantly improve the overall treatment effect, which is worthy of clinical promotion and use.展开更多
