COVID-19 Tanılı Yoğun Bakım Hastalarında Hava Yolu Yönetimi
Özet
COVID-19 tanılı yoğun bakım hastalarında hava yolu yönetimi, yüksek bulaş riski ve ciddi klinik komplikasyonlar nedeniyle son derece kritik bir süreçtir. En yüksek aerosol üretim ve enfeksiyon riski trakeal entübasyon, trakeostomi ve non-invaziv ventilasyon işlemlerinde görülür. Hipoksemi gelişiminde akciğer hasarı, şant fraksiyonları, ventilasyon-perfüzyon kusurları ve nörolojik mekanizmalar etkin rol oynar. Entübasyon kararı; bilinç değişikliği, derin hipoksemi, ciddi asidoz, aşırı solunum sıkıntısı ve organ yetmezliği belirtileri gibi net klinik kriterlere dayanmalı ve kontrollü şekilde erken uygulanmalıdır. Prosedür esnasında sağlık çalışanlarının enfeksiyon riskini azaltmak ve işlemi tek seferde başarıyla tamamlamak için videolaringoskop kullanımı, çift eldiven ve uygun kişisel koruyucu ekipman (KKE) kullanımı zorunludur. Entübasyon sürecinde hızlı seri indüksiyon yaklaşımı benimsenmeli, sedasyon için ketamin ve nöromüsküler blokaj için roküronyum tercih edilmelidir. İşlem sırasında odadaki personel sayısı en aza indirilmeli, kapalı devre iletişim kurulmalı ve preoksijenasyon dikkatle yapılmalıdır. Tüp yerleşiminin doğrulanmasında kontaminasyon riskini artıran stetoskop oskültasyonu yerine kapnografi veya akciğer ultrasonu tercih edilmelidir. Beklenmedik zor hava yolu yönetiminde kurtarma algoritmaları uygulanmalı, ekstübasyonda ise öksürüğü ve aerosol yayılımını en aza indirecek önlemler alınmalıdır. Sonuç olarak, klinisyenlerin yeni yöntemler denemek yerine bildikleri ve deneyimli oldukları güvenli teknikleri kullanmaları hem personel hem de hasta güvenliği açısından önerilir.
Airway management in intensive care patients with COVID-19 is an extremely critical process due to the high risk of transmission and severe clinical complications. The highest risk of aerosol generation and infection is observed during tracheal intubation, tracheostomy, and non-invasive ventilation procedures. Pulmonary damage, shunt fractions, ventilation-perfusion mismatches, and neurological mechanisms play an active role in the development of hypoxemia. The decision to intubate must be based on clear clinical criteria, such as altered consciousness, profound hypoxemia, severe acidosis, significant respiratory distress, and signs of organ failure, and should be performed early in a controlled manner. During the procedure, the use of videolaryngoscopy, double-gloving, and appropriate personal protective equipment (PPE) is mandatory to minimize infection risks for healthcare workers and to achieve first-attempt success. A rapid sequence induction approach should be adopted in the intubation process, prioritizing ketamine for sedation and rocuronium for neuromuscular blockade. The number of personnel in the room during the procedure should be minimized, closed-loop communication must be established, and preoxygenation should be carefully performed. Instead of stethoscope auscultation, which increases contamination risk, capnography or lung ultrasonography should be preferred for confirming tube placement. Rescue algorithms must be implemented in unexpected difficult airway management, and measures should be taken during extubation to minimize coughing and aerosol spread. Consequently, it is recommended for clinicians to utilize safe techniques they are familiar with and experienced in, rather than trying new methods, for both staff and patient safety.
