用护理工时量化法考核ICU护士的绩效

目的探索一种适合ICU护理工作特点的管理模式，提高管理效应。方法用护理工作量、ICU护理质量标准奖惩考核、职称系数三部分综合考评护理工时，与护士的绩效工资分配直接挂钩。结果护理工时量化法实施后，护理质量考核评分，患者？医生对护理质量满意率显著高于实施前（P〈0．05，P〈0．01）。结论护理工时量化绩效分配克服了经验式管理的弊端，建立了有效的激励机制，体现了多劳多得、优劳优得的分配原则，挖掘了护理人员的自身潜力，提高了护理质量。

Can a failed ileal pouch anal anastomosis be left in situ?

OBJECTIVE: Failure after ileal pouch-anal anastomosis (IPAA) is reported with a frequency of 10-20%. The failed IPAA can be excised or defunctioned. Indications for excision and further management of an indefinitely diverted pouch are poorly described. The aim of the present investigation was to investigate pouch-related problems and the histopathological pattern of the pouch mucosa in this group of patients. METHOD: In a cohort of 620 patients having IPAA with a median follow-up of 14 years, 56 patients with failure were identified. The patients with defunctioned pouches were assessed with regard to pouch-related problems and endoscopy with biopsies was performed. Biopsies were stained with haematoxylin-eosin, PAS for neutral mucins and Alcian blue/high iron diamine for sialomucins/sulphomucins. Morphological changes were grouped into three types modified according to Veress and assessed for dysplasia. RESULTS: Twenty-two patients with an indefinitely diverted pouch were found. The follow-up time after surgery for failure was 10 years. Thirteen patients completed the follow-up. Except for two patients with pelvic/perineal pain, there were no clinical problems. The majority of patients displayed mild to moderate macroscopic signs of inflammation. Morphologically, findings ranged from a preserved mucosal pattern to intense inflammatory reaction. No case of dysplasia or carcinoma was found. CONCLUSION: Most patients with an indefinitely diverted pouch had no complaints regarding the pouch. There was no case of dysplasia. Indefinite diversion may be preferable to pouch excision, especially given the associated morbidity.     

Acute diverticulitis – clinical presentation and differential diagnostics

Objective To describe the clinical presentation of acute diverticulitis in an emergency department and to characterize the natural history of diverticulitis in the short perspective. Comparisons are made with an important differential diagnosis, nonspecific abdominal pain (NSAP). Method Patients admitted to our hospital with abdominal pain of up to 7 days’ duration were registered prospectively using a detailed schedule for history, symptoms and signs, from 1 February 1997 to 1 June 2000. Of 3349 patients initially included, 3073 (92%) were eligible for follow up after 1–3 years. Results Acute diverticulitis was the final diagnosis in 145 patients and NSAP in 1142 patients. The incidence of hospitalized patients with diverticulitis was 47 per year and 100 000 population, with a mean hospital stay of 3.3 days. Patients with diverticulitis, more frequently than NSAP, had a longer history and laboratory signs of inflammatory activity. Isolated left abdominal tenderness was more common in diverticulitis, whereas isolated right abdominal tenderness was more common in NSAP. Duration of symptoms on arrival was independent of age and was not correlated to C‐reactive protein, leucocytes or body temperature. Sensitivity of diverticulitis as primary diagnosis was 64% and specificity 97%. Corresponding figures for NSAP were 43% and 90% respectively. Age and gender did not influence diagnostic accuracy or risk of surgery. Conclusion Diverticulitis differs significantly from NSAP in clinical presentation and laboratory parameters. Sensitivity of primary diagnosis for diverticulitis and NSAP was low.     

不同疗法对肌筋膜疼痛病人的自主神经功能的影响

目的：本研究的目的是观察注射疗法及复合小针刀疗法治疗肌筋膜疼痛综合征对自主神经系统功能的影响。方法：选择40例诊断明确的肌筋膜疼痛病人，随机分为两组，每组20例。Ⅰ组：采用注射疗法治疗；IS组：采用注射疗法加小针刀治疗。观察两组病人治疗前后心率变异（HRV）的频域变化，低频LF、超低频LLF、高频HF、低高频比LF／HF及心率变异指数HR-Ⅵ；用视觉模拟评分法（VAS）评定治疗前后疗效并随访观察其远期疗效。结果：①HRV频域指标组内比较：LF、LLF、HF以及HRVI治疗前舆治疗后1min比较有显着性差异（P〈0．05），与5min、10min比较有非常显着性差异（P〈0．01）。LF／HF治疗前与治疗后5min、10min比较有显着性差异（P〈0．05）。组间治疗后1、5、10min，两两比较无显着性差异。②组间比较：病人治疗后临床症状、VAS评分均较治疗前降低．治疗前后IS组有非常显着性差异（P〈0．01）。两组VAS降低率有非常显着性差异（P〈0．01）。③回访病例中，两组治疗有效率比较有显着性差异（P〈0．05）。结论：注射疗法以及复合小针刀疗法均可有效改善肌筋膜疼痛病人的自主神经功能，其机制可能是通过调节、稳定自主神经系统功能达到缓解疼痛。注射疗法复合小针刀疗法的远期疗效优于单纯注射疗法。     

Health-related quality of life and its predictive role for analgesic effect in patients with painful polyneuropathy.

Painful polyneuropathy is a common neuropathic pain condition. The present study describes health-related quality of life (HRQL) in a sample of patients with painful polyneuropathy of different origin and the possible predictive role of HRQL for analgesic effect. Ninety-three patients with a diagnosis of painful polyneuropathy were included in the analysis. Data were obtained from three randomised, placebo-controlled cross-over studies testing the effect of different drugs on polyneuropathic pain (St. John's wort, venlafaxine/imipramine and valproic acid). Patients completed a HRQL questionnaire (SF-36) after a drug-free baseline period and at the end of each treatment period. At baseline, all eight SF-36 scores were lower than in the normal population. No significant differences were found between SF-36 scales during placebo and treatment with valproic acid and St. John's wort. Those two drugs had not shown a pain relieving effect in former analysis. The SF-36 scale of bodily pain (BP) was improved by venlafaxine treatment (p=0.023). General health (GH) and vitality (VT) were improved under treatment with imipramine (GH: p=0.006, VT: p=0.015). In a multivariate logistic regression analysis, baseline SF-36 scores predicted subsequent response to pharmacological treatment. Results show an impaired HRQL in painful polyneuropathy and suggest that HRQL may predict response to analgesic treatment.     

Postoperative pain management—clinical practice is still not optimal

Major progress in clinical pain assessment and management has been achieved in the last decade. More effective analgesic drugs and improved techniques for pain management have been introduced. However, medical reports published during the last few years on postoperative pain management (POPM) indicate that moderate or even severe pain is still rather commonly experienced by surgical patients in the early postoperative period and that worst-pain-episodes may occur even in the late postoperative phase. Insufficient relief of postoperative pain seems a more common problem on surgical wards than on a postanaesthesia care unit (PACU). The aims of POPM are to inhibit autonomic trauma-induced nociceptive impulses that may result in functional disturbances of vital organs and thereby affect the incidence of potentially severe complications influencing clinical outcome. Considering that recent studies continue to show sub-optimal pain management despite the availability of effective drugs and analgesic techniques it must be considered essential to identify possible barriers to effective pain management in clinical practice so that necessary improvements in POPM routines can be carried out.
