Inspite of major advances in monitoring technology and knowledge of fetal and perinatal medicine, perinatal asphyxia is one of the significant causes of mortality and long term morbidity. Data from National Neonatal Perinatal Database suggests that perinatal asphyxia contributes to almost 20% of neonatal deaths in India. "Failure to initiate or sustain respiration after birth" has been defined as criteria for the diagnosis of asphyxia by WHO. Perinatal asphyxia results in hypoxic injury to various organs including kidneys, lungs and liver but the most serious effects are seen on the central nervous system. Levene's classification is a useful clinical tool for grading the severity of hypoxic ischemic encephalopathy. Good supportive care is essential in the first 48 hours after asphyxia to prevent ongoing brain injury in the penumbra region. Strict monitoring and prompt correction is needed for common problems including temperature maintenance, blood sugars, blood pressure and oxygenation. Phenobarbitone is the drug of choice for the treatment of convulsions.
尽管在监测技术以及胎儿和围产期医学知识方面取得了重大进展,但围产期窒息仍是导致死亡和长期发病的重要原因之一。来自国家新生儿围产期数据库的数据表明,在印度,围产期窒息导致了近20%的新生儿死亡。世界卫生组织将“出生后未能启动或维持呼吸”定义为窒息的诊断标准。围产期窒息会导致包括肾脏、肺和肝脏在内的各种器官发生缺氧性损伤,但最严重的影响出现在中枢神经系统。莱文分类法是评估缺氧缺血性脑病严重程度的一种有用的临床工具。窒息后最初48小时内进行良好的支持性护理对于预防半暗带区域持续的脑损伤至关重要。对于包括体温维持、血糖、血压和氧合在内的常见问题,需要进行严格监测并及时纠正。苯巴比妥是治疗惊厥的首选药物。
