Abstract

Aim: Covid 19 affects more than 6,000,000 confirmed cases. It can be asymptomatic in the case of the disease, or it can be observed in simpler symptoms such as fatigue, myalgia, fever, sore throat and dry cough that can be treated on an outpatient basis. However, in more severe cases, septic shock accompanied by dyspnea and/or hypoxemia and especially Acute Respiratory Distress Syndrome (ARDS) may develop. this condition has a high mortality. When there is hypoxemia, cellular anaerobic respiration predominates. In this case, an increase in plasma lactate levels, which is an anaerobic respiratory metabolite, occurs.
Materials and Methods: Patient data were accessed through the patient registration system. Age, gender, comorbidities, blood lactate levels, and lung tomography reports (Co-Rads Classification) of the patients were examined.
Results: 135 cases were excluded. While 43.2% (n=60) of the patients were male, 56.8% (n=19) were female. It was determined that 74.8% (n=104) patients had negative tomography and 25.2% (n=35) patients had positive tomography. When the treatment types of the patients were examined, 49.6% (n=69) were treated as outpatients, 43.2% (n=60) were treated as inpatients in the hospital ward, and 7.2% (n=6) were treated in the intensive care unit. Pulmonary involvement rates of outpatients were the least, increased in those who were treated in the ward, and the highest rate of involvement was found in those who were hospitalized in the intensive care unit. This situation was found to be statistically significant (p<0.001). The lactate level of the patients hospitalized in the intensive care unit was found to be statistically significantly higher than the lactate level of the patients receiving outpatient treatment (p 0.002).
Conclusion: In predicting the disease treatment method in patients with Covid 19; It was suggested that it should be followed in terms of blood lactate level and lung tomography involvement.
