Gebelikte Nonobsetrik Cerrahi İçin Anestezi
Özet
Gebelik sırasında obstetrik olmayan cerrahi ve anestezi yönetimi, tüm gebeliklerin %1,5-2,0'sini etkileyen kritik bir süreçtir. Temel hedef; maternal güvenliği sağlamak, teratojenite riskini minimize etmek ve uteroplasental kan akışını koruyarak fetal asfiksiyi önlemektir. Gebelikteki kardiyovasküler, pulmoner ve gastrointestinal fizyolojik değişiklikler, anestezi yönetimini doğrudan şekillendirir. Özellikle "Supin Hipotansif Sendromu"nu önlemek için hastaya sol yan pozisyon verilmesi hayati önem taşır. Klinik dozlarda kullanılan anestezik ajanların teratojenik etkisine dair kesin kanıt bulunmasa da, organogenez dönemi olan ilk trimestırda elektif işlemlerden kaçınılmalıdır. Fetal oksijenasyonun devamı için maternal kan basıncı ve arteriyel oksijen seviyeleri korunmalıdır. Rejyonel anestezi, sistemik etkilerin azlığı nedeniyle genel anesteziye tercih edilebilir; ancak genel anestezi gerekli olduğunda zor havayolu ve aspirasyon riskine karşı önlem alınmalıdır. Postoperatif dönemde ise fetal kalp atım hızı izlenmeli ve erken doğumu önlemek için etkin ağrı kontrolü sağlanmalıdır. Sonuç olarak, acil cerrahiler multidisipliner bir yaklaşımla güvenle gerçekleştirilebilir.
Anesthesia management for non-obstetric surgery during pregnancy is a critical process affecting 1.5-2.0% of all pregnancies. The primary goals are ensuring maternal safety, minimizing teratogenicity risks, and preventing fetal asphyxia by maintaining uteroplacental blood flow. Physiological changes in cardiovascular, pulmonary, and gastrointestinal systems during pregnancy directly shape anesthesia management. Specifically, placing the patient in a left lateral position is vital to prevent "Supine Hypotensive Syndrome". While there is no definitive evidence of teratogenic effects for anesthetic agents used at clinical doses, elective procedures should be avoided during the first trimester, the period of organogenesis. Maternal blood pressure and arterial oxygen levels must be maintained to ensure continuous fetal oxygenation. Regional anesthesia may be preferred over general anesthesia due to fewer systemic effects; however, when general anesthesia is necessary, precautions against difficult airway and aspiration risks must be taken. In the postoperative period, fetal heart rate should be monitored, and effective pain control must be provided to prevent preterm labor. Consequently, emergency surgeries can be safely performed using a multidisciplinary approach.
