Abstract
Background & objectives: Lung involvement is crucial in patients with Covid-19. The CT scan plays a key role in diagnosing of this disease. This study aimed to survey CT scan involvement patterns in patients with suspected Covid-19 symptoms.
Methods: The present study was cross-sectional,analytical in which the statistical population was patients with typical clinical symptoms of Covid-19 who were referred to the hospital imaging center from March 2019 to May 2019. A total of 301 patients were randomly selected as a sample. Data analysis was performed using SPSS version 26 at a significance level of 0.05.
Results: The average age of the participants in the study was 54.6±17.6. 151 patients (50.2%) were male. 255 patients (84.7%) were treated on an outpatient basis, 37 patients (12.3%) were treated in the Non ICU ward and nine patients (3%) were treated in the intensive care unit(ICU). One hundred sixty eight patients (55.8%) with grand glass conflict, 25 patients (8.3%) with consolidation conflict, 49 patients (16.3%) with linear turbidity were identified while 44 patients (14.6%) had crazy paving, 7 patients (2.3%) had small nodules and 45 patients (15%) had round opacities on contrast-free CT scan. The pattern of conflict in the form of linear turbidity was directly and significantly related to the severity of the disease.
Conclusion: Imaging findings in patients with Covid-19 have a wide range. Despite these findings, attention should be paid to less common and rare signs and symptoms that can help make the right decision and more definitive diagnosis of the disease.

Abstract
Background: One of the major challenges in surgery is pain control after surgery. The present study was conducted with the aim of investigating the role of magnesium sulfate in improving the quality of anesthesia in patients who are candidates for appendectomy surgery.
Methods: In this clinical trial study, 42 people in the control group and 42 people in the intervention group were randomly included. For the intervention group, 50 mg/kg of magnesium sulfate was injected and for the control group, the same amount of distilled water was injected as a placebo. After surgery, the patients were examined for pain, nausea and vomiting, anxiety, blood pressure and heart rate, and the satisfaction of the surgeon in terms of muscle relaxation. Collected data were analyzed in SPSS-26 by statistical methods and p<0.05 was considered as significant level.
Results: The average pain of the patients in the first, third, sixth and twelfth hours of the study in the intervention group with 1.4, 2.66, 3.3 and 3.19 were significantly lower than the control group. In terms of relaxation, a significant difference was observed between the two groups in the first, third, sixth, twelfth and eighteenth hours of the study. In the examination of nausea and vomiting of patients, no significant difference was observed between the two groups. During surgery, a significant difference was observed in patients receiving magnesium sulfate compared to the control group in terms of surgeon satisfaction.
Conclusion: Magnesium sulfate was effective in controlling patients' pain and anxiety and surgeon's satisfaction during surgery, but it was not effective in controlling patients' nausea and vomiting.
