Amaç: End-tidal CO2 (ETCO2) seviyeleri, SpO2 değerlerinden bağımsız olarak hastanın solunum ve metabolik/perfüzyon durumunu yansıtır. Bu çalışma, hastanede yatan COVID-19 hastalarınıda entübasyon ihtiyacını, yoğun bakım ünitesine kabulünü ve mortaliteyi tahmin etmede ETCO2 değerlerinin faydasını araştırmayı amaçladı.
Gereç ve Yöntem: COVID-19 pnömonisi olan toplam 108 hastanede yatan hasta dahil edildi. Solunum parametreleri (oksijen satürasyonu, ETCO2 ve solunum hızı [RR]- O2’li ve O2’siz [w/wo O2]) ve laboratuvar parametreleri ile ilgili veriler kaydedildi.
Bulgular: COVİD-19 hastalarında yoğun bakım ünitesine yatış ihtiyacı, anlamlı olarak daha yüksek ETCO2 değerleri ile ilişkilendirildi. (wO2:27,9 (4,6) vs. 18,6(8,4), p=0.040; woO2: 30,1 (4,9) vs. 23,8 (6,9), p=0.040). Mortalite, daha yüksek RR olasılığı (wO2:32,4 (5,8)’e karşı 24,6 (6,8), p=0.002) ve daha düşük saturasyon (wO2:92,9 (3,8)’e karşı 95,5 (4,2), p=0.025; woO2: 87,1 (5,7) vs. 91,8(6,6), p=0.013) ile ilişkili bulundu.
Sonuç: Bulgularımız, azalmış ETCO2 (w/wo O2) değerlerinin hastaneden taburcu olma olasılığının daha düşük ve yoğun bakım ünitesine transfer olasılığının artmasıyla ilişkisini ortaya koydu. Düşük oksijen satürasyon seviyeleri, hastanede yatan COVID-19 hastalarında hem entübasyon ihtiyacı hem de mortalite riskinin artmasıile ilişkili bulundu.

The utility of ETCO2 value in predicting the progress of the disease and mortality risk in hospitalized patients with COVID-19 pneumonia

Öz

Aim: End-tidal CO2 (ETCO2) levels are reflective of the ventilatory and metabolic/perfusion status of a patient, regardless of his/her SpO2 values. This study aimed to investigate the utility of ETCO2values in predicting the need for intubation, ICU admission, and mortality in hospitalized patients with COVID-19 pneumonia.
Material and Method: A total of 108 hospitalized patients with COVID-19 pneumonia were included. Data on respiratory parameters (oxygen saturation, ETCO2, and respiratory rate [RR]- with and without O2 [w/wo O2]) and laboratory parameters were recorded.
Results: The need forintensive care unit(ICU) admission was associated with significantly higher ETCO2 values (wO2:27.9 (4.6) vs. 18.6(8.4), p=0.040; woO2: 30.1(4.9) vs. 23.8(6.9), p=0.040). Mortality was associated with higher likelihood of higher RR (wO2:32.4(5.8) vs. 24.6(6.8), p=0.002) and lower oxygen saturation (wO2:92.9(3.8) vs. 95.5(4.2), p=0.025; woO2:87.1(5.7) vs. 91.8(6.6), p=0.013). Presence vs. lack of intubation need was associated with significantly increased likelihood of saturation (wO2:93.1(5.3) vs. 95.9(3.8), p=0.013; woO2:87.6(8.3) vs. 92.3(5.9), p=0.007). Hospital discharge vs. ICU stay was associated with significantly higher ETCO2 values (wO2:27.9 (4.6) vs. 18.6(8.4), p=0.040; woO2: 30.1(4.9) vs. 23.8(6.9), p=0.040)
Conclusion: Our findings revealed the association of decreased ETCO2 (w/wo O2) values with a lower likelihood of hospital discharge and increased likelihood of ICU transfer. Low oxygen saturation levels related the increased risk of both intubation need and mortality in hospitalized COVID-19 patients.
