Acute or chronic? Failing left ventricle in a 34 year old

Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.

Anaesthetic Management for A Patient Presenting for Caesarean Delivery with A giant Thymoma - A Case Report

Presentation of a thymoma during pregnancy means that safe delivery becomes more challenging. We present a 33-year-old pregnant woman who was diagnosed with a large thymoma causing marked compression of the tracheobronchial tree and right atrium. After various multidisciplinary meetings she presented for elective caesarean section delivery at 31 weeks of gestation. A combined spinal-epidural anaesthesia was performed, along with colloid pre-and co-loading, and vasopressor support. The delivery was uneventful. The possibility of catastrophic complications was foreseen. Therefore, all requirements for the possibility of airway or haemodynamic collapse were planned carefully, including the possibility of emergent cardiopulmonary bypass.Copyright © 2023, College of Anaesthesiologists of Sri Lanka.

PPP1R13L-Related Cardiomyopathy Stability Following IL1 Inhibition

Introduction: Variants in PPP1R13L are associated with severe childhood-onset cardiomyopathy resulting in rapid progression to death or cardiac transplantation. PPP1R13L is proposed to encode a protein that limits the transcriptional activity of the NFkappaB pathway leading to elevated IL-1, IL-6, and TNF-alpha production in murine models. Optimal medical management for PPP1R13L-related cardiomyopathy is unknown. Here we report usage of a targeted anti-IL-1 immuno-modulatory therapy resulting in cardiac stabilization in a pediatric patient with congenital cardiomyopathy secondary to PPP1R13L variants. Case Report: A 4-year-old boy presented acutely with fever in the setting of persistent abdominal pain, vomiting, fatigue, and decreased appetite for two months following a mild COVID-19 related illness. Echocardiogram revealed severely depressed biventricular systolic function with an ejection fraction of 30%. Due to acute decompensated heart failure symptoms with hemodynamic instability, he was intubated and placed on continuous inotropic infusions with aggressive diuresis. Cardiac MRI demonstrated extensive subepicardial to near transmural fibrosis by late gadolinium enhancement in right and left ventricles. An implantable cardioverter-defibrillator (ICD) was placed due to frequent runs of polymorphic non-sustained ventricular tachycardia. Testing for viral pathogens was positive for rhino/enterovirus. Initial genetic testing was non-diagnostic (82-gene cardiomyopathy panel) but given the patient's significant presentation whole genome sequencing was pursued that showed two separate PPP1R13L variants in trans (c.2167A>C,p.T723P and c.2179_2183del,p. G727Hfs*25, NM_006663.4). Patient serum cytokine testing revealed elevations in IL-10 (4.7 pg/mL) and IL-1beta (20.9 pg/mL). Given the patient's tenuous circumstances and concern for continued progression of his cardiac disease, a trial of IL-1 inhibition via anakinra dosed at 3 mg/kg or 45 mg daily was initiated following hospital discharge. With approximately 6 months of therapy, the patient's cardiac function is stable with normalization of IL-10 and IL-1beta serum levels. Notably, the ventricular arrhythmia decreased after initiation of anakinra with no ICD shocks given. Therapy overall has been well tolerated without infectious concerns. Conclusion(s): In patients with PPP1R13L-related cardiomyopathy, immuno-modulatory therapies should be considered in an attempt to slow cardiac disease progression.Copyright © 2023 Elsevier Inc.

The use of CytoSorb in a septic shock patient with ARDS due to Sars Cov-2

Background: Septic shock is a clinical condition of sepsis aggravated by circulatory, cellular and metabolic dysregulation. Diagnostic criteria include the need for vasopressors to maintain a PAM>65 and serum lactate levels>2 under adequate fluid therapy. Early identification of critically septic patients is necessary to allow early and adequate treatment with improved prognosis. In this case report we evaluate the haemodynamic impact of CytoSorb therapy in a case of septic shock in a patient with ARDS Sars cov2. Method(s): Patient with Sars Cov-2 ARDS was admitted to our department. He was intubated and had a SOFA Score 7. On day 15 the patient presented an increase in PCT CRP and WBC levels with the need for norepinephrine infusion. Empirical antibiotic therapy was started and after 24 hours also CytoSorb Therapy. Four CytoSorb cartridge columns were used. The first two were changed every 12 h and then the next two were changed every 24 h. Result(s): Two days after CytoSorb therapy there was an improvement in haemodynamic without the need of vasopressor support. There was also a reduction in inflammatory parameters and lactates. The trend of these values was shown in figure 1. Conclusion(s): In this case report we evaluated the impact of CytoSorb therapy in a case of septic shock in a patient with ARDS Sars Cov-2. The early use of hemadsorption with CytoSorb combined with re-evaluation of antibiotic therapy resulted in a marked improvement in the patient's clinical status.

CytoSorb on the Septic Shock

Background: Septic shock, defined as organ dysfunction caused by a dysregulated host response to infection, is a condition associated with high morbidity and mortality. One of the hallmarks of sepsis is the excessive release of cytokines and other inflammatory mediators that cause septic shock and multi-organ failure (MOF). New adsorbents are now available as adjuvant therapy aimed at modulating the cytokine "storm" in sepsis. They are thought to be useful if adopted early (within 8-24 hours of the diagnosis of septic shock) in patients who are unresponsive to standard therapy. Here we report our experience with CytoSorb. Method(s): From January 2021 to May 2022, 46 patients with septic shock were treated with continuous renal replacement therapy (CRRT) associated with hemoadsorption with CytoSorb. All cases presented organ failure including AKI. Surgical patients (n = 13) were treated with surgery, COVID patients (n = 15) and medical patients (n = 16) with medical therapy;all surgery cases were operated on before starting the haemadsorption and in some cases reoperation with the need to suspend the adsorption. The mean age was 69 +/- 17 years (SD). On admission the mean SAPSII score was 50 +/- 11 (SD). CRRT as hemodiafiltration (CVVHDF) was performed. All patients received at least one CytoSorb treatment and additional treatments (up to 21 filters in a Covid patient) according to our indication. The CytoSorb cartridge was installed in series to the high cut-off filter;blood flow rates were maintained between 120 and 150 mL/min while dialysis doses from 18 to 45 mL/kg/hour. CytoSorb was renewed every 24 hours. We evaluated the impact of CytoSorb on 30-day survival, haemodynamics and relevant outcomes. Result(s): The 30-day survival was 30%. During treatment with CytoSorb, patients had a hemodynamic stabilization with a significant improvement in MAP, a reduction in amines and a decrease in PCR and PCT (Figure 1). Mortality at 30 days among medical patients was almost comparable to that of COVID patients and higher than that of surgical patients (70%, 69% and 61%, respectively). It should be noted that almost half of the deceased patients arrived late in the hospital, thus leading to a late start of treatment. Conclusion(s): We confirm the efficacy and usefulness of the CytoSorb if adopted early in patients who do not respond to standard therapy. CytoSorb treatment was safe and well tolerated with no device-related adverse events during or after treatment sessions.

Blood purification treatment and cytokine removal using Cytosorb device in critically ill patients with COVID-19 infection

Introduction: Acute kidney injury (AKI) is a complication of SARS-CoV-2 disease, associated with worse clinical outcomes. Renal replacement therapy (RRT) in combination with sequential extracorporeal blood purification therapies (EBPT) might support renal function, attenuate systemic inflammation, and prevent or mitigate multiple organ dysfunctions. Method(s): We retrospectively analyzed 20 patients admitted in ICU for ARDS and who developed moderate-to-severe AKI requiring RRT. Cytokine hemadsorption with Cytosorb was performed in association with CRRT. The main indication for this treatment was the worsening of hemodynamic and respiratory conditions and suspicion of cytokine storm. The protocol consisted in the use of 3-4 cartridges in total;among these, the first 2 were changed after 12 hours of treatment to maximize cytokine removal, while the others after 24 hours. We examined comorbidities, clinical and laboratory characteristics and the impact of treatment in terms of mortality rate and changes in data before and after treatment. Result(s): Nineteen patients (95%) had an AKI at any time during their ICU stay. Of these, 5 patients (25%) had AKI stage II and 14 patients (70%) had AKI stage III. All patients included in this subgroup were mechanical ventilated and required vasopressor's use. Mean prescribed CRRT dose was 31.2 +/- 11.7 ml/kg/h. The median time to strating RRT after ICU admission was 7 days (IQR 3.5-15 days) and the median duration was 7 days (IQR 2.5-12.5 days). Mean SOFA score at the time of RRT start was extremely high (14.5 +/- 2.8). Mortality rate was important (18 patients, 90%) in our cohort. Comparing clinical and laboratory data before and after treatment, a significant improvement of inflammatory markers was reported, with the reduction of C-reactive protein (CRP, 143 [62.1- 328.5] vs 83.5 [66.7-153.5] mg/L);however, no significant changes in IL-6, WBC and PCT values were observed. A slight increase of PaO2/FiO2 were described, although not statistically significant (PaO2/FiO2 ratio 144 [82.7-174.2] vs 183 [132-355.5] mmHg). Conclusion(s): Our experience supports the need of an adequate timing for the use of Cytosorb in critically ill patients with Covid-19. Although a discrete efficacy in improving inflammatory cascade, the late use of EBPT, when organ dysfunction was already ongoing, didn't impact survival.

ST-SEGMENT-ELEVATION MYOCARDIAL INFARCTION in COVID-19

Introduction: The Severe Acute Respiratory Syndrome Coronavirus-2 have been associated with cardiovascular adverse events including acute myocardial infarction due to a prothrombotic and hypercoagulable status, and endothelial dysfunction. Case report: We report the case of a 62-year-old women, admitted to the hospital via the emergency room for acute chest pain and dyspnea. A nasopharyngeal swab was positive for COVID19 real-time reverse transcriptase-polymerase chain reaction 11 day ago. On admission, she was hypotensive with systolic blood pressure measering 87 mmHg and tachycardic with 117 beats/min, oxygen saturation (SO2) was 94%. An 18-lead ECG revealed an infero-postero-lateral ST-elevation myocardial infarction with right ventricular involvement and a seconddegree- Mobitz Type 1 atrioventricular block. The coronary angiography from the right femoral artery showed acute thrombotic occlusion of the first diagonal branch with TIMI 0 flow and acute thrombotic occlusion of proximal right coronary artery with TIMI 0 flow. The most likely diagnosis was myocardial infarction secondary to a non-atherosclerotic coronary occlusion. The angioplasy was performed with dilatations with a semi compliant balloon, bailout implant of BMS, manual thrombus aspiration and intracoronary injection of tirofiban in the right coronary artery. The myocardial revascularization was ineffective. The patient developed significant severe hemodynamic instability and cardiac arrest for pulseless electric activity after 24 hours. Conclusion(s): The COVID-19 outbreak implies deep changes in the clinical profile and therapeutic management of STEMI patients who underwent PCI. At present, the natural history of coronary embolism is not well understood;however, the cardiac mortality rate are hight. This suggests these patients require further study to identify the natural history of the condition and to optimize management to improve outcome.

Dysphagia rehabilitation in post-COVID patients: Review of the literature

COVID-19 causes acute respiratory failure syndrome (SIRA), leading patients to require intubation in the intensive care unit (ICU). A common complication of this ventilatory support is dysphagia, which has a prevalence of up to 30%.This work aims to describe rehabilitation methods in patients with coronavirus infection based on levels of evidence according to the GRADE System, so a systematic review of the literature was carried out. The selected articles were divided into the following subtopics: diagnosis of dysphagia and rehabilitation in COVID patients. The gold standard for the diagnosis of dysphagia is the videofluoroscopic swallowing study (VFS). Fiberoptic Evaluation of Swallowing Assessment (FEES) has high sensitivity and specificity, although they have the disjunction of an aerosol-generating procedure (AGP);however, in a pandemic situation, the study of choice in the literature is VF. Once the diagnosis is made, it is necessary to initiate rehabilitation as soon as possible, even from hospitalization in patients who have hemodynamic stability to prevent long-term effects and promote normal swallowing even before discharge. In patients with COVID-19 infection dysphagia, the risk-benefit of assessment tools and therapy used for diagnosis should be decided to help to maintain social distancing. It becomes imperative to carry out clinical studies with high levels of evidence that allow us to generate Clinical Practice Guides for the benefit of our patients.Copyright © 2021 Sociedad Medica del Hospital General de Mexico.

ECMO in acute fulminant myocarditis in pediatrics

Objectives: To describe our experience in ECMO for acute myocarditis Methods: Descriptive, retrospective study (2018-2022) of a cohort of 8 patients < 16 years with acute myocarditis who were assisted on ECMO. Result(s): 8 patients were collected, (6 females), with a mean age 7;8 years [range 0;1-13;8]. In 7/8, the reason for cannulation was hemodynamic instability refractory to medical treatment, with a mean inotropic score of 70 [range 10-122]. Sixty-two percent presented cardiorespiratory arrest prior to cannulation and 2 of them needed ECRP. The mean precannulation troponin level was 1498 ng/ml [range 89-6212]. Primary transport was performed in 4 patients. ECMO was peripheral veno-arterial in 100%, jugulo-carotid in 2/8 and femoro-femoral in 6/8. All patients underwent atrioseptostomy. They received treatment with levosimendan, immunoglobulins, corticoids and carnitine. In 4 acute infectious etiology was confirmed (parvovirus, influenza and SARSCoV2), another one was due to PIMS-TS and in 3 no etiology was found. Six patients underwent myocardial biopsy and 5 of them showed inflammatory infiltrates. The mean time on ECMO was 8 days [range 3-14], 2 of them requiring 2 ECMO courses. The mean length of PICU stay was 21 days [range 10-50]. Two were transferred to a heart transplant center. The main complications were arterial hypertension (88%), bleeding (63%), neurological (50%), arrhythmias (38%), coagulopathy (38%) and infectious (38%). One patient required renal replacement therapy. 1 patient died, 2 had moderate neurological sequels. Conclusion(s): ECMO is a therapeutic option in patients with fulminant myocarditis refractory to medical treatment and may help improve their prognosis.

ECMO for the immunocompromised pediatric patient: Our experience

Objectives: To present a series of immunosuppressed patients (oncohematological disease, congenital immunosuppression, hematopoietic stem cell (HSCT), and solid organ transplant) assisted on ECMO. Method(s): Descriptive, retrospective study (2011-2020) of a cohort of 9 immunosuppressed patients, supported on ECMO. Medical records were reviewed and demographic, clinical, and analytical variables were collected. Result(s): In our series of 9 patients, 5 were male, the median age was 8 years [RIC 3-11 years]. Considering the underlying disease, 6 were oncologic, 1 liver transplant and 2 with congenital immunodeficiency after HSCT. 4 were under active chemotherapy (median 6 days after the last cycle [RIC 5-188]). 6 were admitted due to acute respiratory failure, 3 due to hemodynamic instability (3/9), (one septic shock). The median PEEP was 12 [RIC 9-15] and FiO2 100% (81-100%). 78% (6) required vasoactive drugs (median inotropic score 35 [RIC 0-75]. 40%. 5 had severe neutropenia and/or plateletopenia in the 24 hours prior to ECMO, and alterations in acid-base balance (median pH 7. 1 [RIC 6.9-7.15]. 5 were on multiorgan failure. TPrimary ECMO transport was performed in 4 patients (44%). Cannulation was peripheral in 80% (57% cervical, 43% femoral) and central in 20%;70% VA-ECMO. Median time of assistance was 15 days [RIC 3.5-31.5] in cardiac ECMO (4), and 29 days [RIC 13.5-42] and in pulmonary ECMO (n=5). The median total time of admission was 45 days [RIC 27-59]. 9 had an infection, 2 COVID after HSCT, and 8 bleeding complications, but only one required surgical revision. Renal replacement therapy was used in 5 (median 9 days [RIC 5-34.5]). Other therapies used were polymyxin hemadsorption(2), intratracheal surfactant(2), plasma exchange(1), infusion of mesenchymal cells(1) and specific memory T lymphocytes(2). 4 patients died, 5 survived decannulation, 2 died later, with an overall survival rate to hospital discharge of 33% (3/9). Conclusion(s): Despite having a worse prognosis, ECMO can increase survival in immunosuppressed patients, in situations that are challenging and require a multidisciplinary approach.

Remote Monitoring for Heart Failure Management at Home.

Early telemonitoring of weights and symptoms did not decrease heart failure hospitalizations but helped identify steps toward effective monitoring programs. A signal that is accurate and actionable with response kinetics for early re-assessment is required for the treatment of patients at high risk, while signal specifications differ for surveillance of low-risk patients. Tracking of congestion with cardiac filling pressures or lung water content has shown most impact to decrease hospitalizations, while multiparameter scores from implanted rhythm devices have identified patients at increased risk. Algorithms require better personalization of signal thresholds and interventions. The COVID-19 epidemic accelerated transition to remote care away from clinics, preparing for new digital health care platforms to accommodate multiple technologies and empower patients. Addressing inequities will require bridging the digital divide and the deep gap in access to HF care teams, who will not be replaced by technology but by care teams who can embrace it.

General Anesthesia Strategies for Safe, Rapid Recovery, Fast Turnaround, and Same-Day Discharge for Complix Abalations in the Ep-Specialized Asc Setting

Background: Many EP procedures are moving from the hospital to the ambulatory surgery center (ASC) outpatient setting. The COVID-19 pandemic and the CMS Hospitals Without Walls (HWW) program has been an impetus in accelerating this transition. Anesthesia provider perioperative management is critical in facilitating safe procedures with rapid, same-day discharge. Our EP-dedicated 2-OR ASC completed more than 3,000 procedures and more than 500 left-sided ablations utilizing general anesthesia with endotracheal intubation with same-day discharge. To our knowledge, this experience is unique within an ASC setting in both volume and complexity. Objective(s): We present our comprehensive anesthesia strategy and lessons learned to facilitate safe, efficient procedures and discharge in an EP ASC. Method(s): A nurse anesthesiologist with more than a decade of EP-dedicated experience developed and taught a perioperative anesthesia strategy to facilitate high volume, safe and quick discharge care. Fundamental to this is the avoidance of opioids and benzodiazepines whenever possible. Propofol or general anesthesia with sevoflurane and complete reversal with sugammadex allow for quick recovery. Mandatory video laryngoscope utilization minimizes airway trauma, while liberal antiemetic use eliminates most nausea. All femoral access is device closed. Positive inotropes are used liberally during anesthetic to avoid heart failure. The goal is to deliver all patients to PACU on room air with stable hemodynamics. Anesthesia providers manage the preop and recovery area. Result(s): More than 90% of all patients undergoing general anesthesia and heparinization for left-atrial ablation were discharged home in under 3 hours. Nearly all procedures not requiring femoral access were discharged within 30-60 minutes. High procedure volumes with efficiencies far exceeding our in-hospital experience were thus facilitated with improved patient safety. Since HWW began, five patients have required transfer to the hospital without any deaths. All others were discharged same day. Conclusion(s): We suggest that a dedicated anesthesia team with a tailored perioperative anesthesia plan facilitates performing nearly all EP-related surgical procedures in an ASC. This success is facilitated by appropriate patient selection, preoperative evaluation, intraoperative care prioritizing quick return to baseline, and end-to-end anesthesia perioperative management. We believe this type of anesthesia management is critical to the transition of EP procedures to ASCs.Copyright © 2023

Preliminary Investigation on Wrist Temperature Control by Wearable Peltier Armband

Due to COVID-19 pandemic, body temperature measurement in commercial facilities is performed using a non-contact method. However, if the human body can be controlled in some way to disguise body temperature, a thermometer would have difficulty detecting an entrant with a fever. In this study, we propose a method to control body temperature measured at the wrist in order to demonstrate the vulnerability of temperature measurement at the wrist. Our device lowers body temperature by cooling the upper arm, thereby cooling blood flow and reducing the intensity of infrared radiation detected by a thermometer. The implemented device was used to cool the upper arm under three different conditions. The results showed that cooling the blood flow in the upper arm can lower the body temperature at the wrist. The cooled body temperature was difficult to maintain after the end of cooling, irrespective of the cooling intensity and cooling time. © 2022 ACM.

Secondary infections in critically ill patients with COVID-19: effects of intravenous IgM-enriched immunoglobulin therapy

Introduction: Critically ill patients with severe COVID-19 have an increased risk of bacterial and fungal superinfections due to a dysregulated immune response characterized by lymphopenia and low immunoglobulins levels. The intravenous immunoglobulins are involved in pathogen/toxin scavenging and inhibition of inflammatory mediators gene transcription with anti-apoptotic effects on immune system cells. This research aimed to describe the effects of intravenous IgM-enriched immunoglobulins in COVID-19 patients with sepsis due to secondary infections and low IgM levels. Method(s): We performed an observational retrospective study, including patients admitted to our intensive care unit (ICU) between March 2020 and February 2021 with severe COVID-19 and sepsis due to a superinfection (known or suspected) treated with intravenous IgM-enriched immunoglobulins. We collected demographic data and comorbidities. We noted hemodinamic data, antimicrobial and adiuvant therapies, laboratory results at ICU admission (T0), at the beginning (T1) and at the end (T2) of the IgM-enriched immunoglobulins infusion and at ICU discharge (T3). Result(s): In our cohort of 36 patients (Table 1) the prevalence of documented secondary infections was 83%. We observed a significant reduction of leukocytes from T0 to T3 (10.4 [8.3-14.5] x 103/ mmc vs 7.1 [4.8-11.2] x 103/ mmc, p < 0.01) and the SOFA score from T0 to T2 (7 [6-19] vs 5 [3-7], p < 0.01) and from T0 to T3 (7 [6-10] vs 4 [2-9], p < 0.01);from T1 to T2 (7 [6-9] vs 5 [3-7], p < 0.01) and from T1 to T3 (7 [6-9] vs 4 [2-9], p < 0.01). Cardiovascular SOFA showed a statistically significant reduction from T1 to T2 (4 [3-4] vs 0 [0-3], p < 0.01). Conclusion(s): The IgM-enriched immunoglobulins could improve organ function, as evidenced by the reduction of the SOFA score. Although the latest Surviving Sepsis Campaign guidelines suggest against using of IgM-enriched immunoglobulins, our study supports its use as an adjunctive therapy in COVID-19 patients with septic shock.

COVID-19 and intensive care

COVID-19 caused by SARS-CoV2 has spread rapidly across the world, resulting in many patients in need of intensive care support. Severe pneumonia, acute respiratory distress syndrome (ARDS), sepsis/septic shock, and multi-organ failure may occur during the disease course among many other complications. There still is not a definite cure, but supportive care is important to minimize complications. Patients in need of respiratory support and interventions should preferably be placed in negative pressure isolation rooms, with utmost care to decrease viral spread. Points to consider during oxygen therapy, non-invasive and invasive mechanical ventilation, and shock management of COVID-19 patients are discussed. Patients with mild hypoxia may be managed with conventional oxygen therapy, while others will benefit from high flow nasal oxygen therapy and mechanical ventilation. Although corticosteroids are not recommended for other viral pneumonia, there are recent reports suggesting that steroids may have a place in the treatment of COVID-19 patients with hypoxia. Shock may complicate the course of the disease and a search for the etiology of shock should be carefully planned. Thromboembolic events are common;prophylaxis and/or treatment of thromboembolic events should be managed according to the guidelines. Meanwhile, the results of ongoing randomized, controlled trials on antiviral and immunomodulatory agents are expected to offer better treatment options for COVID-19 patients in the near future.Copyright © 2020 Bilimsel Tip Yayinevi.

Critical illness in patients with omicron variant COVID-19: different but crucial

Introduction: During the COVID-19 pandemic, various virus variants evolved worldwide. COVID-19 omicron (CO) was associated with a decrease in length of hospital stay, ICU admission and death [1] as compared to COVID-19 delta (CD). To estimate impact of CO on ICUs worldwide, we investigated characteristics, disease course and outcome of critically ill CO patients. Method(s): Of 8562 critically ill COVID-19 patients included in the prospective international multicenter RISC-19-ICU registry [2,3], characteristics and outcome were compared for 1890 CD and 272 CO patients admitted to ICU between 1-2021 and 9-2022. Mixed model analysis corrected for individual center effects and adjusted for age, sex, vaccination status, use of steroids and anticoagulants was used. Result(s): There was no difference in age, sex and BMI between groups. CO patients had more comorbidities [mean difference (MD) 0.7, 95% CI (0.5-1.0), p = 0.02], especially arterial hypertension, and higher SAPS II score [MD 0.0 (0-0.1), p < 0.001], SOFA score [MD 0.1 (0.1-0.3), p < 0.0001]. CO patients presented with higher cardiovascular system SOFA subscore, but better PF-ratio at ICU admission and smaller risk for intubation and mechanical ventilation throughout their ICU stay [OR 0.5 (0.3-0.8)]. There was no difference in ECMO treatments, ICU length of stay [MD 0.6 (0-11.4), p = 0.72] or ICU survival [HR 1 (0.7-1.5), p = 0.88] between the two groups. Conclusion(s): We show that critically ill CO patients present with more comorbidities, less severe respiratory disease but more severe hemodynamic instability at ICU admission as compared to CD patients, although the ICU length of stay and mortality was similar. These differences could be explained by differences in disease characteristics caused by CO, or by the increasing prevalence of CO as co-factor to preexisting disease. Continued monitoring of critically ill CO patients in ICUs worldwide is warranted.

A nationwide cohort study of pregnant and postpartum patients with severe COVID-19 pneumonitis in ICU in Israel

Introduction: This study included pregnant patients with severe COVID to test the hypothesis that the impact of delivery on maternal outcome depends upon illness severity at the time of delivery;we hypothesized that patients not yet requiring IPPV would improve following delivery (due to improvement in respiratory mechanics), while patients already on IPPV, or close to requiring ventilation, would deteriorate (due to maternal cardiovascular intolerance to autotransfusion). Method(s): This multicenter, prospective/retrospective cohort study evaluated Israeli ICU admissions of pregnant women with COVID-19 pneumonitis from 1-Feb-2020 to 31-Jan-2022. We assessed maternal, neonatal outcomes and longitudinal maternal clinical data. The primary outcome was maternal outcome (no-IPPV, IPPV, ECMO, death). The primary longitudinal outcome was SOFA score, the secondary longitudinal outcome was the novel PORCH score (PEEP, Oxygenation, Respiratory-support, Chest-X-ray, Haemodynamic-support). Patients were classified into: no-delivery, postpartum admission, deliverycritical and delivery-not-critical groups. Result(s): 84 patients in 13 ICUs were analysed;there were 34 nodelivery, 4 postpartum, 32 delivery-critical, 14 delivery-not-critical patients. Delivery-critical and postpartum had worse outcomes with, 26/32(81%) and 4/4(100%) requiring IPPV;12/32(38%) and 3/4(75%) requiring ECMO;1/32(3%) and 2/4(50%) dying. Deliverynot- critical and no-delivery had far better outcomes with, respectively, 6/34(18%) and 2/14(14%) requiring mechanical ventilation;no patients required ECMO or died. SpO2, S/F ratio, P/F ratio in Deliverycritical deteriorated on the day of delivery, continued to deteriorate, and took longer to recover;delivery-not-critical improved rapidly following delivery. The day of delivery was a highly significant covariate for PORCH (p < 0.0001), not SOFA (p = 0.09). Conclusion(s): Interventional delivery should be considered for maternal indications before patients deteriorate and require IPPV.

Lung ultrasound scoring system vs ROX index as a predictor for progression to the invasive mechanical ventilation in COVID-19 patients

Background: During the outbreak of the highly contagious Coronavirus disease 19 (COVID19), rapid and simple prognostic tools were needed to support clinical decisions and predict the need of invasive mechanical ventilation. the ROX index, and the lung ultrasound score (LUSS) were proposed to objectively predict patient prognosis in addition to the subjective clinical assessment Aim: This study aimed to compare lung ultrasound score with ROX index in predicting the need of invasive ventilation in COVID-19 patients requiring advanced oxygen therapy. Patients and Methods: We studied 50 patients with severe COVID-19 pneumonia in the intensive care unit in the isolated area at Kasr Al-Ainy hospital. Complete Medical history, physical examination and laboratory investigations were obtained on admission. All patients underwent bedside lung ultrasonography scan and LUSS was calculated at the 2nd and the 12th hours, also ROX index was calculated at the 2nd, 6th and 12th hours from initiating the advanced oxygen therapy. Result(s): From a total of fifty patients with COVID-19, 56.0% were males, with mean age of 65.98 + 11.68 years, and mortality rate was 68%. The optimal cut off value of the ROX index at (2, 6, 12 hour) is (2.495, 2.675, 3.06) respectively, (p <0.001) with sensitivity 90.9% and specificity 76.5% at the 12 hour. Also the optimal cut off point of LUSS is 25.50 (p <0.001) with sensitivity 93.9% and specificity 88.2% for prediction of the invasive mechanical ventilation. Conclusion and recommendations: The study concluded that LUSS is more sensitive in predicting the need of invasive mechanical ventilation than ROX index.Copyright © 2023, Codon Publications.
