Abstract

Introduction: To evaluate surgical risk and post-operative quality of living status in patients over 85 years of age after transurethral vaporization resection of the prostate (TUVRP).

Methods: Sixty patients over 85 years of age underwent TUVRP were compared with 228 patients less than the age of 80 years. Group A was 60 patients greater than 85 years of age, Group B was 137 patients from 71 to 79 years of age, and Group C was 91 patients from 60 to 70 years of age.

Results: In Group A, pre-operative ASA grade was higher than the other two groups, compared with Group C, p?<?0.01. Operating time was 40.03?±?18.90?min, compared in the three groups, p?>?0.05. Follow-up was obtained in 49 (81.67%) patients; of them 10 patients were deaths with a survival time of 22.90?±?11.14 months. In the 39 survivors, post-operative IPSS score was 11.17?±?6.9, compared with Group B, p?>?0.05 and Group C, p?<?0.01. Quality of Life (QOL) index was 1.11?±?0.80, compared with Group B, p?<?0.001 and Group C, p?<?0.01. Barthel Index score in 16 patients was >60 and the score was 82.81?±?8.56 pre-operatively. The patients with >60 were increased to 19 cases and the score was improved to 90.93?±?7.58 (p?<?0.001) in follow-up.

Conclusion: Surgical risk in patients over 85 years of age was higher than patients less than the age of 80 years. A safety TUVRP could improve their voiding function and activities of daily living.  相似文献

The focus of this article is on professional activity in the operating theater. We explore how surgeons and nurses organize their activities, how social interaction is used to help structure and define situations, and how differentials in knowledge are constructed and oriented to. We utilize some ideas and concepts from symbolic interactionism, ethnomethodology, and conversation analysis to analyze small clips of audio‐ and video‐recorded interaction. Focusing on how surgeons and nurses request, provide, and apply surgical instruments, the analysis shows how surgical work is accomplished through talk and bodily conduct. We conclude that, examined in detail, the social interaction between surgeons and nurses is analytically inseparable from the “technical” demands of their work.  相似文献

Abstract

Sterilization plants process all reusable materials used in hospitals during different stages of healthcare provision. Most items sterilized come from the surgical theater in the form of individual instruments, linen and surgical trays. Reducing the number of instruments in trays impacts on the performance of the sterilization process. Here, we propose a three-phase method, based on lean healthcare principles, cluster analysis and kaizen groups of experts to rationalize surgical trays, reducing sterilization processing costs. We innovate by proposing a strategy to approach tray rationalization prioritizing surgical specialties that are both complex and frequent, and by using group technology to cluster surgical trays expediting expert analyses carried out by kaizen groups. Our propositions were tested in a high complexity, tertiary care hospital, covering 12 surgical specialties, reducing the number of instruments by average 9.75%, and the time-to-assemble trays by average 9.68%, obtaining annual savings of US$285.756,00 in sterilization processing costs.  相似文献

在我国,胃癌属于一种较为常见的恶性肿瘤疾病。随着老龄化社会的到来,老年胃癌患者数量不断增多。目前胃癌的主要治疗方式包括手术、放化疗、内镜介入治疗,还有靶向治疗、基因治疗、免疫治疗等。各种治疗手段都有一定的特点和局限性,单独依靠某一种治疗方法很难取得理想效果。随着内镜介入治疗技术的应用,新型化疗和靶向药物的问世以及新辅助治疗理念的发展,临床取得了不错的疗效,显著改善了患者的预后,延长了患者的生存,提高了患者的生活质量。  相似文献
