医疗卫生服务价格改革方向初探

医疗卫生服务价格改革是要理顺价格构成成份之间量的关系，使每个构成成份的价格值都在供求关系的约束中，在政府的有效管制中，从而成为医疗卫生资源合理配置的有效工具。为此：①对生产要素分别定价；②对劳动定价；③对资本和自然资源定价；④确定医疗卫生机构内部管理时劳动价格；⑤价格中的所有构成成份价格都置于供给和需求关系约束下；⑥确定医疗卫生服务价格的理想传递方式。     

神经导航辅助显微手术治疗脑功能区肿瘤

目的探讨神经导航系统辅助下脑重要功能区肿瘤显微手术的治疗效果和应用价值。方法1999年12月～2002年6月应用StealthStation神经导航系统辅助切除邻近脑重要功能区肿瘤10例,对神经导航系统术中应用的优越性、精确性等进行分析。结果本组平均注册误差为(2.8±0.9)mm,肿瘤和重要解剖功能结构定位准确,肿瘤全切除率77.8%。术后神经功能未受明显影响,无手术并发症及死亡。结论神经导航系统对于切除邻近脑重要功能区肿瘤具有定位准确,动态示踪和实时导航,侵袭性小,安全、可靠等特点,有助于提高肿瘤全切率及降低手术并发症。     

细孔钻颅穿刺术对肿瘤的临床应用(附9例报告)

应用细孔钻颅穿刺术诊断和治疗颅内肿瘤9例,7例有颅内压增高症状和神经功能缺失。9例中囊性肿瘤6例,囊液最少者15ml,最多者115ml,平均50ml,穿刺放液后症状均改善,为手术赢得了时间;3例实质性肿瘤,穿刺活检有助于星形细胞瘤的确诊。

近端胆管癌的外科治疗

目的 探讨近端胆管癌的外科治疗及疗效。方法 57例近端胆管癌患者中21例行外科手术治疗,36例行非手术外引流治疗。结果21例手术治疗患者中17例存活14月以上,36例行鼻胆管引流或内置管引流术患者均在8月内死亡。结论 外科手术治疗近端胆管癌疗效明显优于鼻胆管引流术（ENBD）或内置管引流术（EHBD）胆管内外引流。     

Postoperative Cognitive Dysfunction in Middle-aged Patients

Background: Postoperative cognitive dysfunction (POCD) after noncardiac surgery is strongly associated with increasing age in elderly patients; middle-aged patients (aged 40-60 yr) may be expected to have a lower incidence, although subjective complaints are frequent.

Methods: The authors compared the changes in neuropsychological test results at 1 week and 3 months in patients aged 40-60 yr, using a battery of neuropsychological tests, with those of age-matched control subjects using Z-score analysis. They assessed risk factors and associations of POCD with measures of subjective cognitive function, depression, and activities of daily living.

Results: At 7 days, cognitive dysfunction as defined was present in 19.2% (confidence interval [CI], 15.7-23.1) of the patients and in 4.0% (CI, 1.6-8.0) of control subjects (P < 0.001). After 3 months, the incidence was 6.2% (CI, 4.1-8.9) in patients and 4.1% (CI, 1.7-8.4) in control subjects (not significant). POCD at 7 days was associated with supplementary epidural analgesia and reported avoidance of alcohol consumption. At 3 months, 29% of patients had subjective symptoms of POCD, and this finding was associated with depression. Early POCD was associated with reports of lower activity scores at 3 months.
