Objective To investigate the risk factors of pneumonia associated to elderly patients with cerebral stroke.Methods Totally 248 elderly patients with stroke were retrospectively analyzed on medical history,treatment and prognosis.Results In 248 cases of senile stroke patients,78 cases had an associated pneumonia,accounting for 31.5％.The onset with admission period ≥48 h was in majority (48 cases),less than 48 h in 30 cases (38.5％).12 patients (15.4％)were involved blood culture,38 cases sputum culture,accounting for 48.7％.In the univariate correlation analysis,older age,consciousness,basic diseases,stroke location,NIHSS score of nasal feeding therapy were associated with associated pneumonia (all P＜0.05).As compared to patients without no associated pneumonia,the patients with associated pneumonia had more aged and higher proportions of bulbar paralysis and impaired consciousness,more underlying diseases.At the time of admission,increased occurrences of National Institute of Health Stroke Scale (NIHSS) score,brainstem stroke and multiple feeding treatment appeared in most of patients.Multivariate Logtistic regression analysis showed that age≥ 65 years,history of pulmonary disease,bulbar paralysis,disturbance of consciousness,nasal treatment among older stroke were the associated pneumonia risk factors.The hospitalized time was prolonged [(31.3±20.4)d and(17.6±8.1)d,t＝7.57,P＝0.001] and fatality rate increased (41.0％ vs.4.1％) in patients with pneumonia than without pneumonia(x2＝ 54.96,P＝ 0.000).The independent factors of death were aged ≥ 75 years(OR＝1.6,95％CI:1.0-2.6),NIHSS＞13 (OR＝5.0,95％CI:1.7-24.6) and pulmonary infection(OR＝5.2,95％ CI:1.8-17.3).Conclusions The occurrence of associated pneumonia in elderly patients with cerebral stroke is related with age,underlying disease,state of consciousness and NIHSS scores.The prevention and treatment of relevant factors can improve prognosis.

BACKGROUND:Articular capsule ligaments can lead articular surface to move normally and limit the excessive movement, especially to prevent any non-physiological movement. They are the important structures for stabilizing hip joints. It was previously thought that articular capsule should be routinely resected in the total hip arthroplasty (THA). OBJECTIVE: This study was designed to investigate the effect of retaining articular capsule in THA through posterior approach on maintaining hip stability. DESIGN, TIME AND SETTING: This study, a retrospective case analysis, was performed on 61 patients with femoral neck fracture, who received treatment in the Department of Orthopedics, Xiangya Second Hospital of Central South between January 2005 and December 2006. PARTICIPANTS: Twenty-nine patients who underwent THA with retaining articular capsule from January to December 2006 were included as retaining group, and thirty-two patients who underwent THA with routine resection of partial articular capsule were included as routine group. The two groups were kept identical in case selection, prosthesis selection, post-surgery processing and operators. METHODS: Four holes were drilled on greater trochanter on the proximal femoral bone. The superior part of articular capsule valve was sutured to the superior part of original articular capsule using No.1-0 absorbing thread, then sutured to base of femoral neck in mattress manner, and the suture was not ligated. The inferior part of articular capsule valve was sutured to the inferior part of original articular capsule using another suture. And the suture passed through two bone holes on base of femoral neck. The lower limbs were externally rotated and the suture was ligated. Subsequently, the excised extortor was repaired. Prior to and subsequent to suture, hip was slowly bent for 90° and femur was internally rotated for45°to investigate the suture of articular capsule on strengthening articular stability. MAI OUTCOME MEASURES: Operation time, bleeding volume and hip dislocation after THA. RESULTS: The operation time and bleeding volume were lower in the retaining group than in the routine group (P < 0.05). After THA, hip dislocation did not occur in any patients in the retaining group but occur in 2 patients (6.2%) in the routine group. Statistical tests could not be performed due to less data, resulting in no statistical significance.CONCLUSION: There has been no precise conclusion about the effects of retaining articular capsule or not on hip stability.But retaining articular capsule shortens operation time, reduces intrao-perative bleeding, unable raise operation risk, and re-establishes hip soft tissue balance.

Objective To study the influencing factors on the time of acute cerebral apoplexy patients visiting the hospital.Methods 64 patients with acute ischemic stroke were researched.The clinical data of all patients were collected.The influencing factors on treatment time were analyzed by univariate and multivariate Logistic regression analysis.Results In the 64 patients, 26 cases of the visiting time≤6 h(40.63%), 38 cases of visiting time>6 h(59.37%).The results of single factor analysis showed that the relationship between the time of treatment,pre-hospital transfer mode (x2=6.650,5.081,all P<0.05),educational level,living location,MRS score,whether or not know the stroke(x2=4.561,6.557,8.788,4.146,all P<0.05);the disturbance of consciousness and symptoms ≥3 symptoms compared with the visiting time had significant difference(x2=5.133,5.926,all P<0.05);in the multiple factors Logitic regression analysis,the degree of education(OR=2.332,95%CI:1.402~3.904),severity of illness(OR=3.956,95%CI:1.934~7.446),understanding of stroke(OR=3.621,95%CI:1.563~8.125),disturbance of consciousness(OR=4.336,95%CI:2.394~11.374),pre-hospital transport mode(OR=5.658,95%CI:2.546~12.554) were the risk factors of treatment time.Conclusion There is a close relationship with extension and various factors of acute ischemic stroke patients,in the future,not only need to improve the pre-hospital emergency care system,but also need to strengthen the public understanding of the disease.
