人工髋关节置换术后脂肪栓塞综合征的观察与护理

笔者报道人工髋关节置换术后脂肪栓塞综合征的护理措施认为重视氧饱和度及动脉血氧分压监测，注意观察中枢神经系统症状和呼吸系统症状，及时发现并纠止低氧血症，对不同的病人制定不同护理方案，严密观察病情，及时掌握病情变化：是护理的关键。     

Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.

不同免疫剂治疗扩张型心肌病患儿心功能和临床预后评价

目的观察比较泼尼松联用硫唑嘌呤和大剂量静脉用免疫球蛋白(IVIG)对扩张型心肌病(DCM)患儿心功能及预后的影响。方法将DCM患儿20例分为治疗Ⅰ和Ⅱ组,分别在传统抗心衰治疗基础上加泼尼松联用硫唑嘌呤和大剂量IVIG,治疗1个疗程后评价心功能,检测治疗前后左房横径(LA)、左室舒张期内径(LV)、左室射血分数(LVEF)、心脏指数(CI),并计算其治疗前后变化。所有病例随访1年,计算1年存活率。结果治疗Ⅱ组心功能明显优于治疗Ⅰ组(P均<0.05);两组LA、LV、LVEF和CI治疗后较治疗前均有明显改善(P均<0.05);治疗Ⅰ组各参数变化明显低于治疗Ⅱ组(P均<0.05),其1年存活率明显低于治疗组Ⅱ(P<0.05)。结论泼尼松联用硫唑嘌呤和大剂量IVIG均能改善DCM患儿心功能,但IVIG疗效优于泼尼松联用硫唑嘌呤。     

社区干预治疗对促进脑梗死患者功能恢复效果分析

目的探讨社区干预治疗对促进脑梗死患者功能恢复的效果。方法以自愿的方式选择通州区经委社区卫生服务站和八里桥社区卫生服务站所管辖社区内38例脑梗死恢复期患者随机分为治疗组和对照组,对治疗组患者进行为期1年的社区干预治疗,比较治疗组与对照组患者功能恢复情况(日常生活活动能力)。结果通过1年的早期社区干预治疗,治疗组较对照组患者功能恢复效果明显提高(P<0.01)。结论早期社区干预治疗对脑梗死患者功能恢复有促进作用。     

同步放化疗治疗中晚期食管癌60例

目的 观察对中晚期食管癌患者同步放化疗,疗效及毒副作用.方法 中晚期食管癌120例,随机分放化疗组60例(简称放化组)和单纯放疗组60例(简称单放组).放疗采用常规分割,DT40 Gy后缩小照射野,避开脊髓斜野照射,加量DT20～30 Gy,6～7周完成.放化组放疗1、4周后应用顺铂(DDP)20 mg/d、亚叶酸钙(CF)0.1 g/d,CF静脉滴注1/2量时5-氟尿嘧啶(5-Fu)500 mg/d静脉滴注,连续5 d为1个周期,化疗当天进行放疗.结果 放化组与单放组1、2、3年生存率分别为67%、46%、34%和52%、38%、24%;放射性肺炎分别为14例和12例;外周血细胞下降分别为26例和17例;胃肠道反应分别为25例和9例;死亡分别为38例和48例.两组治疗效果比较差异有统计学意义(P＜0.05).结论 放疗同步PLF方案化疗治疗中晚期食管癌生存率高,毒副作用及不良反应低.
