An obstetric fistula is a traumatic childbirth injury that occurs when labor is obstructed and delivery is delayed. Prolonged obstructed labor leads to the destruction of the tissues that normally separate the bladder from the vagina and creates a passageway (fistula) through which urine leaks continuously. Women with a fistula become social outcasts. Universal high-quality maternity care has eliminated the obstetric fistula in wealthy countries, but millions of women in resource-poor nations still experience prolonged labor and tens of thousands of new fistula sufferers are added to the millions of pre-existing cases each year. This article discusses fistula prevention in developing countries, focusing on the factors which delay treatment of prolonged labor.
Obstetric fistulas can be prevented through contraception, avoiding obstructed labor, or improving outcomes for women who develop obstructed labor. Contraception is of little use to women who are already pregnant and there is no reliable screening test to predict obstruction in advance of labor. Improving the outcome of obstructed labor depends on prompt diagnosis and timely intervention (usually by cesarean section). Because obstetric fistulas are caused by tissue compression, the time interval from obstruction to delivery is critical. This time interval is often extended by delays in deciding to seek care, delays in arriving at a hospital, and delays in accessing treatment after arrival. Communities can reasonably demand that governments and healthcare institutions improve the second (transportation) and third (treatment) phases of delay. Initial delays in seeking hospital care are caused by failure to recognize that labor is prolonged, confusion concerning what should be done (often the result of competing therapeutic pathways), lack of women's agency, unfamiliarity with and fear of hospitals and the treatments they offer (especially surgery), and economic constraints on access to care.
Women in resource-poor countries will use institutional obstetric care when the services provided are valued more than the competing choices offered by a pluralistic medical system. The key to obstetric fistula prevention is competent obstetrical care delivered respectfully, promptly, and at affordable cost. The utilization of these services is driven largely by trust.
产科瘘是一种分娩时发生的创伤性损伤,如果分娩受阻且分娩时间延长,就会发生这种损伤。长时间的梗阻性分娩会导致正常分隔膀胱和阴道的组织受损,并形成一个通道(瘘管),尿液会不断从这个通道漏出。患有瘘管的女性会被社会排斥。在富裕国家,普及高质量的产妇护理已经消除了产科瘘,但在资源匮乏的国家,仍有数百万人经历长时间的分娩,每年都有数千名新的瘘管患者加入到已经存在的数百万例患者中。本文讨论了发展中国家的瘘管预防问题,重点讨论了延迟治疗梗阻性分娩的因素。
产科瘘可以通过避孕、避免梗阻性分娩或改善梗阻性分娩妇女的结局来预防。对于已经怀孕的妇女来说,避孕的作用不大,而且没有可靠的筛查试验可以在分娩前预测梗阻。改善梗阻性分娩的结局取决于及时诊断和及时干预(通常是剖宫产)。由于产科瘘是由组织压迫引起的,从梗阻到分娩的时间间隔至关重要。这种时间间隔通常会因寻求治疗的决策延迟、到达医院的延迟以及到达后接受治疗的延迟而延长。社区可以合理地要求政府和医疗机构改善第二(运输)和第三(治疗)阶段的延迟。最初在寻求医院治疗方面的延迟是由于未能认识到分娩时间延长、对应该采取什么措施的困惑(通常是由于竞争治疗途径造成的)、妇女缺乏自主权、对医院及其提供的治疗方法的不熟悉和恐惧(尤其是手术)以及获得治疗的经济限制造成的。
在资源匮乏的国家,当提供的服务比多元化医疗系统提供的竞争选择更有价值时,妇女将使用机构产科护理。产科瘘预防的关键是提供尊重、及时和负担得起的产科护理。这些服务的利用在很大程度上取决于信任。
