Postpartum hemorrhage today: ICM/FIGO initiative 2004-2006. 总被引:3,自引:0,他引:3

Postpartum hemorrhage (PPH) is the main cause of maternal mortality. Yet, even though solutions have been identified, governments and donor countries have been slow to implement programs to contain the problem. While poverty and low educational level remain the underlying cause of PPH, the current literature suggests that active management of the third stage of labor can prevent it. The International Confederation of Midwives (ICM) and the International Federation of Gynecology and Obstetrics (FIGO) are attempting to address the chronic PPH crisis by educating their members on best practices and on troubleshooting where resources are inadequate. Some studies found oxytocin to be preferable to misoprostol in settings where active management is the norm. However, secondary clinical effects may prove more troublesome with oxytocin than with misoprostol, and misoprostol may prove to be more practical and equally effective in low-resource settings. Two new interventions are also proposed, the anti-shock garment and the balloon tamponade. 相似文献

随着我国教育体制改革的推进,高等学校的资金来源也发生了较大变化,创收收入成为高校收入中的很大一部分,高校的各个基层单位的创收收入也在不断增加,对于这部分资金的管理,有着十分重要的现实意义。目前的创收收入管理比较松散,存在很多弊病。需要通过纳入学校财务统一管理、严格创收分配支出管理、制定创收分成比例、定期检查等办法加强管理,使这部分资金得到合理利用,促进高校的教育、教学的发展。 相似文献

Convulsive status epilepticus (CSE) in childhood is a medical emergency and its aetiology and outcome mean that it should be studied separately from adult CSE. The incidence in developed countries is between 17 and 23/100,000 with a higher incidence in younger children. Febrile CSE is the commonest single group with a good prognosis in sharp distinction to CSE related to central nervous system infections which have a high mortality. The aim of treatment is to intervene at 5 min and studies indicate that intravenous (i.v.) lorazepam may be a better first-line treatment than rectal diazepam and i.v. phenytoin a better second-line treatment than rectal paraldehyde. An epidemiological study strongly supports the development of prehospital treatment with buccal midazolam becoming a widely used but unlicensed option in the community. More than two doses of benzodiazepines increase the rate of respiratory depression without obvious benefit. The 1 year recurrence rate is 17% and the hospital mortality is about 3%. 相似文献

We describe a model of how physician assistants can be used in an academic medical center to expand radiologist productivity, and to enhance the departmental academic and educational missions. At Harborview Medical Center, following a training program and graduated responsibility under supervision, physician assistants provide initial interpretation of radiology studies, consultation to referring physicians, and perform less complicated interventional procedures. Acceptance of physician assistants by the radiologists, radiology residents, and referring physicians has been high. Although the impact of physician assistants on departmental clinical productivity is difficult to measure, our data suggest that radiologists are more efficient when physician assistants are assigned to service, both in terms of numbers of studies interpreted, and timeliness of reporting and billing. As a result of the success of our program, we believe that physician assistants can have an important role in radiology practice. 相似文献

The gastric vasculature responsible for intraoperative bleeding in endosocpic submucosal dissection (ESD) is the ramified vascular network occupying the middle of the submucosal layer and large vessels penetrating the muscle layer. Appropriate management for these vessels must be addressed. The trimming of the ramified vascular network can be safely performed with coagulation mode following shallow mucosal cutting. A large penetrating vessel usually requires precoagulation prior to dissection. These procedures are effectively performed with the water jet short needle knife (Flush knife). 相似文献

Recommendations for the diagnosis and management of Alzheimer's disease and other disorders associated with dementia: EFNS guideline 总被引:4,自引:0,他引:4
G. Waldemar B. Dubois M. Emre J. Georges I. G. McKeith M. Rossor P. Scheltens P. Tariska B. Winblad 《European journal of neurology》2007,14(1):e1-e26
The aim of this international guideline on dementia was to present a peer-reviewed evidence-based statement for the guidance of practice for clinical neurologists, geriatricians, psychiatrists, and other specialist physicians responsible for the care of patients with dementia. It covers major aspects of diagnostic evaluation and treatment, with particular emphasis on the type of patient often referred to the specialist physician. The main focus is Alzheimer's disease, but many of the recommendations apply to dementia disorders in general. The task force working group considered and classified evidence from original research reports, meta-analysis, and systematic reviews, published before January 2006. The evidence was classified and consensus recommendations graded according to the EFNS guidance. Where there was a lack of evidence, but clear consensus, good practice points were provided. The recommendations for clinical diagnosis, blood tests, neuroimaging, electroencephalography (EEG), cerebrospinal fluid (CSF) analysis, genetic testing, tissue biopsy, disclosure of diagnosis, treatment of Alzheimer's disease, and counselling and support for caregivers were all revised when compared with the previous EFNS guideline. New recommendations were added for the treatment of vascular dementia, Parkinson's disease dementia, and dementia with Lewy bodies, for monitoring treatment, for treatment of behavioural and psychological symptoms in dementia, and for legal issues. The specialist physician plays an important role together with primary care physicians in the multidisciplinary dementia teams, which have been established throughout Europe. This guideline may contribute to the definition of the role of the specialist physician in providing dementia health care. 相似文献
