Abstract

A 25 year- old woman with rheumatic heart disease at 32 weeks of her pregnancy who had uındergone mitral valve thrombectomy and prosthesis implantation and cesarean section in the same session was reported. She had three open heart operations when she was nine years old. She developed progressively deteriorating shortness of breath at the 30th weeks of gestation. Emergency surgery was performed when dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea and expiratory rales were developed due to thrombosis of mechanical mitral valve. The operation had been initiated by an obstetrician with cesarean section to save the fetus, and then mitral valve thrombectomy and prosthesis implantation were performed.. Acute lung oedema had been noted during anesthesia induction. Lung protective mechanical ventilation (LPMV) technique with low tidal volume (6-8 mL kg-1), high frequency (20/min) and high PEEP (7 mmHg) values has been applied. Peak airway pressure was limited to 32 mmHg. The patient had been extubated at postoperative 2. day, and discharged without further complications at postoperatively 7th day. The main hemodynamic effects of the LPMV strategies are decreased cardiac output and systemic arterial pressure potentially reducing organ perfusion. This therapy reduces hypoxic pulmonary vasoconstriction and hypercapnia, thus lowering pulmonary artery pressure, unloading right ventricle and stabilizing hemodynamics. We conclude that implementing intraoperative LPMV strategies might be effective in patients undergoing open heart operation with acute lung injury.

Özet

Aynı seansta sezaryen ve mitral kapak trombektomisi çıkarılan ve protezi yerleştirilen yirmi beş yaşında, romatizmal kalp hastalığı olan 32 haftalık gebe kadın olgu bildirildi. Hasta dokuz yaşında iken 3 kere açık kalp operasyonu geçirmiştir. Gestasyonun 30. haftasında ilerleyici solunum sıkıntısı gelişmiştir. Mekanik mitral kapak trombüsüne bağlı dispne, ortopne, paroksismal noktürnal dispne ve raller gelişince acil cerrahi yapıldı. Operasyon fetüsü korumak amacıyla bir kadın doğum uzmanı tarafından başlatıldı ardından mitral kapak trombektomi ve protezi gerçekleştirildi. Anestezi indüksiyonu sırasında akut akciğer ödemi tespit edildi. Akciğer koruyucu mekanik ventilasyon (AKMV) tekniği uygulandı. Düşük tidal volüm (6-8 mL kg-1), yüksek solunum frekansı (20/min) ve yüksek PEEP (7 mmHg) uygulandı. Peak hava yolu basıncı 32 mmHg ile sınırlandırıldı. Operasyonun ertesi günü hasta başarılı bir şekilde ekstübe edildi ve herhangi bir komplikasyon olmadan operasyondan 7 gün sonra taburcu edildi. AKMV stratejilerinin başlıca hemodinamik etkileri, organ perfüzyonunu azaltması olası bir kardiyak output ve sistemik arteryel basınçta düşmedir. Bu tedavi pulmoner vazokonstriksiyon ve hiperkapniyi azaltarak pulmoner arter basıncını düşürür, sağ ventrikül yükünü azaltır ve hemodinamikleri düzeltir. Akut akciğer hasarı olan ve açık kalp cerrahisi uygulanan hastalarda intraoperatif AKMV stratejilerinin etkili olabileceği sonucuna vardık.
