Tetanus remains a leading cause of maternal and neonatal morbidity and mortality in developing countries. It is caused by the release of two toxins produced by Clostridium tetani, a noninvasive gram-positive anaerobic bacillus. Tetanospasmin is taken up by the neuronal end plates and prevents neurotransmitter release at the synaptic junction. This leads to spasms and is irreversible. Recovery requires the formation of new neurons and may take months. Generalized muscle spasm, respiratory compromise, and autonomic dysfunction are all common clinical manifestations. Diagnosis is based mainly on history and clinical examination. The management of the pregnant woman is similar to the nonpregnant individual. The main objectives are prompt prevention of further toxin absorption, wound debridement, antibiotic therapy, and aggressive supportive care. Primary and secondary prevention protocols are important worldwide because tetanus is a preventable disease. The tetanus toxoid vaccine can be given in pregnancy.
破伤风仍然是发展中国家孕产妇和新生儿发病及死亡的主要原因。它是由破伤风梭菌(一种非侵袭性革兰氏阳性厌氧杆菌)产生的两种毒素释放所致。破伤风痉挛毒素被神经终板摄取,阻止神经递质在突触连接处释放。这会导致痉挛且不可逆。恢复需要形成新的神经元,可能需要数月时间。全身肌肉痉挛、呼吸功能不全和自主神经功能障碍都是常见的临床表现。诊断主要基于病史和临床检查。孕妇的治疗与非孕妇相似。主要目标是迅速防止毒素进一步吸收、伤口清创、抗生素治疗以及积极的支持性护理。由于破伤风是一种可预防的疾病,初级和二级预防方案在全球都很重要。破伤风类毒素疫苗可在孕期接种。
