The effect of ageing on the pharmacokinetics of dihydrocodeine

Summary Although poor renal function reduces clearance of dihydrocodeine in man, and renal impairment occurs with ageing, no significant differences occurred in the handling of single doses of dihydrocodeine between elderly patients and young, normal subjects.After multiple dosing, the maximum concentration was significantly different between the groups, being higher in the elderly. The increase in the area under the curve in the elderly was 25% greater than in the young on chronic therapy. This difference was not statistically significant, but was likely to be of clinical significance.The elderly patients' mean creatinine clearance (61.8 ml per min) was significantly lower than that in the young (137 ml per min), and there was a significant correlation between the half-life at single dosing and the blood urea concentration.Variability in all measurements was marked in both groups, and hence no clear guidelines can be given on therapeutic dosing. The small initial dose with alterations thereafter depending on clinical effect is the best advice.     

Hernia repair in elderly patients under unmonitored local anaesthesia is feasible

Background: There is a growing interest in the use of local anaesthesia for inguinal hernia repair. It certainly seems to be an acceptable alternative for the elderly. Supporting intravenous sedation, however, still requires monitoring, anaesthetic personnel and some preparations for the patient. Therefore we set up a feasibility study of hernia repair under local anaesthesia without intravenous sedation or monitoring in elderly patients. Method: A total of 62 patients (aged 65 years or more) with unilateral inguinal hernia received a Mesh Plug Repair. Prospectively collected data included procedure-related complications and information on pain and quality of life as measured by Short Form 36. Results: No procedure-related complications were noted. Comparing the preoperative scores, the SF-36 on day 14 (n=61) did not differ significantly. After a median follow-up of ten months (n=54), significantly higher scores were found for scales of physical and emotional role and pain (all p<0.05). Twenty-two patients reported some form of pain (40.7%). 94.4% of the patients would recommend the procedure when asked. Conclusion: The results of this study indicated that Mesh Plug Repair performed under unmonitored local anaesthesia with no intravenous sedation is a feasible alternative for elderly patients. It has advantages for the medical organization without disadvantages for the patient.     

精神分裂症患者及家属、医生对知情同意具体程序态度的初步分析

目的分析精神科医生、精神分裂症患者及其家属对知情同意具体程序的态度，以指导今后知情同意的实施。方法所有样本均来自中南大学湘雅二医院，共计55名患者，46名家属，61名医生。采用知情同意态度问卷，来调查精神科医生、精神分裂症患者及其家属对知情同意具体程序的态度。结果患者、家属、精神科医生非参数检验结果表明，共计有17项条目存在显著性差异。比如条目4“签写一份接受医疗服务的知情同意书，其目的是”，67．4％的家属，59．2％的患者，90．2％的医生选择第3项“既保护医生又保护患者”，仅21．7％的家属，26．5％的患者，1．6％的医生选择第2项“保护患者”。结论目前精神分裂症患者、家属以及精神科医生对知情同意具体程序的态度存在明显差异。     

三级医院病人就诊流向探讨

研究通过对包括专科医院在内的多家三级医院住院病人资料的分析，将疾病种类按ICD－9编码分为19类，研究各类疾病应往低级别医院分流的比例。结果表明：各大类疾病的分流比例不同，分流比例较高的主要是常见病和多发病，总的分流比大约在60％左右。
