Making a Difference in Eye Care of the Critically Ill Patients.

Ocular surface disorders are frequently encountered in patients under sedation and paralyzed patients in intensive care units (ICUs). In the ICUs, treatment is usually focused on the management of organ failures, and eye care becomes a side issue. As a result, ophthalmological complications do occur (incidence ranges from 3.6% to 60%) and are frequently overlooked in this setting. To identify the best available evidence in providing the best eye care to prevent exposure keratopathy, a literature review was performed. The databases of PUBMED, COCHRAN, and EMBASE library were searched. We only looked at higher quality articles. Among various eye care measures that have been advocated to prevent exposure keratopathy, the most effective is the application of polyethylene covers. Early diagnosis and effective treatment will help prevent microbial keratitis and visual loss.

Prognostic markers in patients with COVID-19 requiring intensive care support.

Objectives: Several hematological and immunological markers, particularly neutrophil count, predict the severity of COVID-19. This study aimed at assessing hematological and coagulation parameters at different time points, to predict the complications or outcomes of patients with COVID-19 admitted to the intensive care unit (ICU). Methods: We conducted a prospective observational multicenter study in ICU departments. A total of 118 patients with COVID-19 admitted to the ICU were included. Clinical data and blood samples from routine hematology and coagulation tests were collected at admission, and on days 3, 7, and 14. The main outcome measures were high-flow-O2 requirement, thrombosis, and 30-day mortality. Results: The venous thromboembolism score increased from a mean of 5.10 ± 2 on day 0 to 6.40 ± 2.80 on day 14 (P = 0.0002). The disseminated intravascular coagulation (DIC) score significantly correlated with thrombosis (P = 0.031). A total of 41.20% of patients in the ICU had a DIC score ≥4, and 11.40% had a score <4. Mortality was negatively associated with patients on high-flow O2, 9 patients (10.80%) (P = 0.040), and positively associated with patients receiving ventilation, 16 patients (27.50%) (P < 0.001). An increase in white blood cell count (subdistribution hazard ratio (SHR): 0.91; 95% CI: 0.80-1) and neutrophil count (SHR: 1; 95% CI: 1.01-1.05) was associated with greater disease severity and D-dimer level (SHR: 1.60; 95% CI: 1.10-2.5). Conclusion: The venous thromboembolism score was significantly higher for patients who died than those who recovered. Furthermore, mechanical ventilation was associated with high mortality, whereas the risk of thrombosis and ICU admission correlated with high D-dimer values and DIC scores. Therefore, D-dimer levels and DIC scores are prognostic markers that may predict disease severity in patients with COVID-19.

Point prevalence of delirium among critically ill patients in Saudi Arabia: A multicenter observational study.

Background: Delirium in critically ill patients is independently associated with poor clinical outcomes. There is a scarcity of published data on the prevalence of delirium among critically ill patients in Saudi Arabia. Therefore, we sought to determine, in a multicenter fashion, the prevalence of delirium in critically ill patients in Saudi Arabia and explore associated risk factors. Methods: A cross-sectional point prevalence study was conducted on January 28, 2020, at 14 intensive care units (ICUs) across 3 universities and 11 other tertiary care hospitals in Saudi Arabia. Delirium was screened once using the Intensive Care Delirium Screening Checklist. We excluded patients who were unable to participate in a valid delirium assessment, patients admitted with traumatic brain injury, and patients with documented dementia in their medical charts. Results: Of the 407 screened ICU patients, 233 patients were enrolled and 45.9% were diagnosed with delirium. The prevalence was higher in mechanically ventilated patients compared to patients not mechanically ventilated (57.5% vs. 33.6%; P < 0.001). In a multivariate model, risk factors independently associated with delirium included age (adjusted odds ratio [AOR], 1.021; 95% confidence interval [CI], 1.01-1.04; P = 0.008), mechanical ventilation (AOR, 2.39; 95% CI, 1.34-4.28; P = 0.003), and higher severity of illness (AOR, 1.01; 95% CI, 1.001-1.021; P = 0.026). Conclusion: In our study, delirium remains a prevalent complication, with distinct risk factors. Further studies are necessary to investigate long-term outcomes of delirium in critically ill patients in Saudi Arabia.

The Saudi Critical Care Society extracorporeal life support chapter guidance on utilization of veno-venous extracorporeal membrane oxygenation in adults with acute respiratory distress syndrome and special considerations in the era of coronavirus disease 2019.

Extracorporeal membrane oxygenation (ECMO) is considered as a supportive treatment that provides circulatory and ventilatory support and can be thought off as a bridge to organ recovery. Since 2009, it has been applied as a rescue treatment for patients with severe adult respiratory distress syndrome (ARDS) mainly due to viral causes. In December 2019, several patients presented with a constellation of symptoms of viral pneumonia in China. A new strain of the corona virus family, called COVID-19, has been discovered to be the cause of this severe mysterious illness that was named severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2). This new virus continued to spread across the globe leading to the World Health Organization announcing it as a pandemic in the early 2020. By the end of March 2021, the number of COVID-19 cases worldwide exceeded 126 million cases. In Saudi Arabia, the first confirmed case of COVID-19 was reported in the 2nd March 2020. By the end of March 2021, the total number of confirmed COVID-19 cases in Saudi Arabia is just above 360,000. In anticipation of the need of ECMO for the treatment of patients with SARS­CoV­2 based on the previous Middle East respiratory syndrome coronavirus pandemic experience, the Saudi Extra-Corporeal Life Support (ECLS) chapter that is under the umbrella of the Saudi Critical Care Society (SCCS) convened a working group of ECMO experts. The mission of this group was to formulate a guidance for the use of ECMO as a last resort for patients with severe ARDS, especially with COVID-19 based on available evidence. The ECLS-SCCS chapter wanted to generate a document that can be used to simple guide, with a focus on safety, to provide ECMO service for patients with severe ARDS with a special focus on SARS­CoV­2.

Treatment of Middle East Respiratory Syndrome with a combination of lopinavir-ritonavir and interferon-ß1b (MIRACLE trial): study protocol for a randomized controlled trial.

BACKGROUND: It had been more than 5 years since the first case of Middle East Respiratory Syndrome coronavirus infection (MERS-CoV) was recorded, but no specific treatment has been investigated in randomized clinical trials. Results from in vitro and animal studies suggest that a combination of lopinavir/ritonavir and interferon-ß1b (IFN-ß1b) may be effective against MERS-CoV. The aim of this study is to investigate the efficacy of treatment with a combination of lopinavir/ritonavir and recombinant IFN-ß1b provided with standard supportive care, compared to treatment with placebo provided with standard supportive care in patients with laboratory-confirmed MERS requiring hospital admission. METHODS: The protocol is prepared in accordance with the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) guidelines. Hospitalized adult patients with laboratory-confirmed MERS will be enrolled in this recursive, two-stage, group sequential, multicenter, placebo-controlled, double-blind randomized controlled trial. The trial is initially designed to include 2 two-stage components. The first two-stage component is designed to adjust sample size and determine futility stopping, but not efficacy stopping. The second two-stage component is designed to determine efficacy stopping and possibly readjustment of sample size. The primary outcome is 90-day mortality. DISCUSSION: This will be the first randomized controlled trial of a potential treatment for MERS. The study is sponsored by King Abdullah International Medical Research Center, Riyadh, Saudi Arabia. Enrollment for this study began in November 2016, and has enrolled thirteen patients as of Jan 24-2018. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02845843 . Registered on 27 July 2016.

The rapid response team in outpatient settings identifies patients who need immediate intensive care unit admission: A call for policy maker.

BACKGROUND: Caregivers in the ambulatory care setting with differing clinical background could encounter a patient at high risk of deterioration. In the absence of a dedicated acute care team, the response to an unanticipated medical emergencies in these settings is likely to have a poor outcome. OBJECTIVE: To describe our experience in implementing an intensivist-led rapid response team (RRT) in the outpatient settings that identified patients who needed immediate Intensive Care Unit (ICU) admission. The effect on in hospital arrests, mortality, and ICU outcome is not the scope of this study. MATERIALS AND METHODS: This retrospective descriptive study was performed from January 1, 2009 to December 31, 2011 in a tertiary hospital. Data from hospital records were used (none from patients' records). Consent was not needed. MEASUREMENTS: Direct ICU admissions from the outpatient areas. RESULTS: There were 90 patients cared for by RRT in the outpatient's settings, 76 adult, and 14 pediatric patients. A total of12 adult patients were transferred directly to ICU. Among the patient who were transferred to the emergency department, additional four patients required to be transferred to ICU (total 16 patients [17.7%], 15 adult, and one pediatric patient). Follow-up at 24 h in the ICU showed death of one adult oncology patient (6.25%), and discharge of two patients (12.5%). Nine patients (81%) were still sick to require longer ICU stay. CONCLUSION: Intensivist-led RRT in outpatient settings identifies patients who are critically ill and in need of immediate ICU admission. Thus, an intensivist-led RRT policy in the outpatient settings needs to be implemented hospital wide.
