ABSTRACT
Background: Among the medications administered for the management of COVID-19 patients, the induction drugs used for intubation have received little attention. The aim of this study was to compare the effect of induction drugs on the mortality of patients with COVID-19 requiring intubation. Methods: In this retrospective study, all patients who were admitted to Shahid Sadoughi and Shahid Rahnemoun hospitals in Yazd from February to March 2020 with definitive diagnosis of COVID-19 and needed intubation were enrolled. Patients were divided into 4 groups based on the type of drugs used in intubation, and mortality rate was assessed at the end of the first, second, fourth, and seventh days of the study. Statistical analyses were performed using SPSS 20 and P values <.05 was considered significant. Results: In this study, 76 patients were examined. Patients were divided into 4 groups, of which 21 were in etomidate group, 8 in ketamine group, 21 in sodium thiopental group, and 35 in midazolam group. Mortality rate in these 4 groups was 25%, 12.5%, 14.3%, and 14.3% (p=0.822), respectively at the end of the first day after intubation; it was 83.3%, 12.5%, 28.6%, and 25.7% (p=0.001), respectively, at the end of the second day; it was 83.3%, 12.5%, 42.9%, and 42.9% (p=0.015), respectively, until the end of the fourth day; it was 100%, 25%, 61.9%, and 65.7% (p=0.007), respectively, until the end of the seventh day. Admission to intubation time interval was 0.91±0.99, 3.12±1.95, 4.09±2.44, and 4.74±2.62 days, respectively (p<0.001). Conclusion: The results of this study suggest that the use of etomidate may be associated with higher mortality in COVID-19 patients. Further studies are needed to verify the results of this study.
ABSTRACT
BACKGROUND: Patients with cancer might be at an increased risk of infection with COVID-19 and a more severe disease course. However, different tumor types have differing susceptibility to the infection and COVID-19 phenotypes. Thus, the risk and prevalence of COVID-19 is not uniform across the different tumor types. Here, we performed a meta-analysis to estimate the risk and prevalence of COVID-19 infection in colorectal cancer (CRC) patients. METHODS: A comprehensive literature search was performed up to July 25, 2020, thorough PubMed, Web of Science, Scopus, Google Scholar, CNKI, CBM, China Science, Wan Fang, and SciELO databases. The risk of COVID-19 infection in CRC patients was performed based on the odds ratios (ORs) and 95% confidence interval (95% CI). RESULTS: A total of six studies with 204 different cancer patients with COVID-19 and 92 CRC infected patients with COVID-19 were selected. Our results showed that the prevalence of COVID-19 infection in CRC patients was 45.1% in the global population. The pooled data showed that there is no a significant risk of infection with COVID-19 in CRC patients in the global population (OR = 0.261, 95% CI 0.099-0.533, p = 0.082). However, when subgroup analysis was performed based on country of origin, we found a significant correlation in Chinese CRC patients (OR = 0.221, 95% CI 0.146-0.319, p ≤ 0.001). CONCLUSIONS: This study results revealed that Chinese CRC patients harbored a higher risk of COVID-19 infection. However, more multicenter, larger sample sizes and high-quality studies are required to verify this meta-analysis result.
