Abstract: (229 Views) |
Background and Aim: Considering that the mortality rate is high in Covid-19 patients, especially those hospitalized in the intensive care unit, and various factors are involved in its occurrence, therefore, it seems that the examination of arterial blood gases at the beginning of hospitalization of patients and also Serial evaluations can be effective in the management and treatment of the aforementioned patients. The Aim of the study was to investigate the parameters of arterial blood gas in patients with Covid-19 hospitalized in the ICU department of Imam Khomeini Hospital, Ardabil.
Materials and methods: In this cross-sectional descriptive study, 197 patients diagnosed with COVID-19 and hospitalized in intensive care units in Ardabil city were studied. Demographic information (including age, gender, medical history, medication history, etc.) and clinical information (symptoms of illness, recovery or death, etc.) and arterial blood gas information in terms of acid-base changes were extracted from the patient records and recorded in a checklist designed for each patient.
Results: 85 patients (43.1%) were male and 112 patients (56.9%) were female. The mean pH of the patients was 7.25±0.28, the mean PaO2 of the patients was 76.14±13.89, the mean PaCO2 of the patients was 40.08±5.95, and the mean HCO3 of the patients was 25.30±5.01. None of the ABG parameters were significantly different by gender and disease outcome. 29 cases (12.9%) had metabolic acidosis, 31 cases (13.8%) had metabolic alkalosis, 84 cases (37.5%) had respiratory acidosis, 41 cases (18.3%) had respiratory alkalosis, and 12 patients had normal acid-base disorders.
Conclusion: Patients who were hospitalized due to symptoms of COVID-19 had a high rate of acid-base disorders. They experienced a variety of acid-base changes. Respiratory acidosis and respiratory alkalosis were the most common acid-base disorders in this group of patients. |
