Analysis of Maternal Critical Care at the Mid Yorkshire Hospitals NHS Trust

Introduction: Perinatal admissions to Critical Care are increasing due to rising maternal age, obesity, and comorbid disease.1 The MBRRACE Report 2021 stated that of 191 maternal deaths in 2017-2019, only 17% had good care.2 Since the COVID-19 pandemic, there was a subjective increase in perinatal admissions to Mid Yorkshire Hospitals Critical Care. Objective(s): To investigate whether MYH Critical Care maternal admissions have increased, if there has been a change in admission trends and to evaluate the care of critically ill pregnant and postpartum women compared to FICM standards.3 Methods: Retrospective audit of notes of all pregnant and up to 6 weeks postpartum women admitted to critical care between 24/02/2019 and 05/09/2021. Data collected included gestation, duration of admission, organ support, days reviewed by obstetrics and mortality outcomes. Result(s): * There was 1 maternal death and 3 fetal deaths during the study period * 50% of the admissions were antenatal and 50% were postnatal * During the COVID-19 pandemic we have seen a 47% increased rate of admissions from 1 per 29 critical care bed days to 1 per 19 critical care bed days * 50% of patients were supported with ventilation and CPAP during admission, 13% with CPAP only. Prior to the COVID pandemic, no maternal admission required CPAP on our Critical Care unit during the data collection period * 63% of patients were reviewed by obstetrics at least one during their admission, but obstetric review was documented on only 37 of 112 patient days * There is no critical care SOP for perimortem Caesarean section * There is no specialist neonatal resuscitation equipment available on ICU * There is no named ICM consultant responsible for Maternal Critical Care * There is no SOP for support of maternal contact with baby * There is no critical care/obstetric services MDT follow-up Conclusion(s): This study shows that Critical Care admissions have increased, and that care does not follow all the FICM recommendations. Considering this, the following recommendations have been made: * Introduce an SOP and simulation training for peri-mortem section * Introduce neonatal resuscitation equipment box * Nomination of a named ICM Consultant lead for Maternal Critical Care to ensure quality of care and act as liaison * Train critical care staff in supporting contact between a mother and baby, with support from midwifery services * Introduction of Obstetric and Critical Care MDT follow-up.

The impact of COVID-19 on extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA): A single centre study

Objectives: The COVID-19 pandemic has been affecting everything including ECMO service. At the moment we have to equip PPE before ECPR and we thought it may influence on time to establish venoarterial ECMO and patient outcomes. Method(s): We compared OHCA-patients who underwent ECPR in our hospital before (January 2015 - March 2020) and after (April 2020 - December 2022) the Government of Japan declared a state of emergency in relation to COVID-19. Result(s): There were 32 and 9 patients in the pre- and post-COVID-19 pandemic sample. Of these, 9 (28.1%) vs. 5 (55.6%) survived extracorporeal life support (ECLS), p=0.23, and 4 (12.5%) vs. 2 (22.2%) had good neurologic outcomes (cerebral performance category 1- 2) after ECLS. Seven (21.9%) vs. 1 (12.5%) were discharged or transferred alive from the hospital (one patient of the post-COVID-19 cohort has been still hospitalised for rehabilitation), p>0.99. Mean values of low-flow time were respectively 67.3 minutes (SD 18.3) and 55.6 minutes (SD 17.1), p=0.091, and median values of time to establish ECMO from admission were respectively 32.5 minutes (IQR 15.8) and 26.0 minutes (IQR 4.0), p=0.23. Conclusion(s): There were no differences in time-toECMO or outcomes in patients who underwent ECPR for refractory OHCA before and after the COVID-19 pandemic.

Bleeding disorders associated with severity of respiratory failure in covid-19 patients: A prospective observational study

INTRODUCTION: Despite the progress in understanding the pathophysiology of coagulopathy in COVID-19, data about the association and phasing of pathological changes in various parts of the hemostatic system with the development of acute respiratory distress syndrome (ARDS) are insufficient. OBJECTIVE: To determine association between the severity of respiratory failure and pathological changes in the hemostatic system in COVID-19 patients. MATERIALS AND METHODS: A prospective observational study included 204 patients with a confirmed diagnosis of severe and extremely severe COVID-19. Two groups were identified according to disease outcome: Fatal (n = 106) and survived (n = 98) groups. To assess dynamics of the clinical picture of the disease and to study the hemostatic profile, time points were determined: I point — the first day — admission to intensive care unit;II point — 3-5 days, III point — 7-10 days after ICU admission. The respiratory index was calculated to assess the severity of respiratory distress syndrome. Statistical data processing was carried out using the statistical software package MedCalc Version 20.110 (MedCalc Software Ltd, Belgium). RESULTS: A 2.15-fold decrease in the respiratory index was determined for fatal outcome in patients with severe and extremely severe COVID-19. The most important hemostatic parameters affecting the severity of respiratory failure are increased Willebrand factor concentration at I point of the study (21% contribution and inverse correlation), increased plasminogen activator inhibitor type 1 (PAI-1) level on 3-5 days (35% contribution and direct correlation), and activation of the coagulative component of hemostasis on 7-10 days (78% contribution and direct correlation). CONCLUSIONS: The severity of respiratory failure in patients with a confirmed diagnosis of severe and extremely severe COVID-19 is gradually associated with endotheliopathy (1 day), inhibition of parietal fibrinolysis (3-5 days) and activation of the coagulative component of hemostasis by 7-10 days of ICU stay. © 2023, Practical Medicine Publishing House LLC.

Emergency Medical Services: COVID-19 crisis.

The COVID-19 epidemic required rapid and frequent adaptations from the prehospital emergency medical services (EMS). The exposure of EMS providers is significant, particularly during procedures at risk of aerosolization such as advanced airways management or cardiopulmonary resuscitation. EMS personal need to be equipped with appropriate personal protective equipment and trained in its use. Interhospital transfers from COVID-19 patients are complex and involve mainly intubated patients. The possible shortage of resources may motivate the implementation of dedicated prehospital triage and orientation recommendations, which should be consistent with the hospital processes.Copyright © 2020 Editions Medecine et Hygiene.

QIP leading to significant improvement in DNAR-form completion for COVID-19 patients on intensive care

Background: This QIP was initially conducted during COVID-19 because there were concerns that many patients on the intensive care unit did not have a DNAR form. The pandemic has been a time where establishing appropriate ceilings of care is particularly important. Many of the patients on intensive care had been admitted due to haematological complications arising from COVID-19 including pulmonary embolism, thrombocytopenia and disseminated intravascular coagulation. Lack of DNAR forms has serious implications including the inappropriate use of cardiopulmonary resuscitation and uncertainty for the medical team regarding ceilings of care for critically unwell patients. These were the main drivers for change. Method(s): Data were collected over a 12-month period on ICU from the critical care electronic and written records. This included the presence of a DNAR form, time from ICU admission to DNAR form completion, as well as accuracy and detail on the form. Result(s): Only 50% of patients had a DNAR form completed and of these, cardiopulmonary resuscitation was only recommended in 27% cases. Time taken for completion of the form ranged from 0 to 20 days. Following discussion of these concerning findings in the ITU departmental meeting, several changes were made including mandatory discussions and adding DNAR status for each patient onto handover sheets, as well as electronic reminders for DNAR status. The second cycle of the QIP showed a 35% improvement with 85% of patients having a completed DNAR form. Conclusion(s): This QIP highlights the importance of DNAR form completion for all patients, given that only 27% of the 50% patients who had completed DNAR forms were deemed suitable for CPR. It also shows that introducing measures that make DNAR discussions mandatory leads to an improvement in DNAR form completion. Given the success in intensive care, this QIP has now been expanded to the high dependency unit and haematology wards to improve DNAR form completion for all haematology patients.

Predictors of poor outcomes in patients with pandemic viral infections (influenza AH1N1pdm09, COVID-19) on a ventilator.

Considering the commonality of the pathogenetic links of the critical forms of COVID-19 and influenza AH1N1pdm09 (cytokine over-release syndrome), the question arises: will the predictors of an unfavorable outcome in patients on mechanical ventilation and, accordingly, the universal tactics of respiratory support in these diseases be identical? Objective. In a comparative aspect, to characterize patients with influenza AH1N1pdm09 and COVID-19 who were on mechanical ventilation, to identify additional clinical and laboratory risk factors for death, to determine the degree of influence of respiratory support (RP) tactics on an unfavorable outcome in the studied category of patients. Patients and methods. Patients treated on the basis of resuscitation and intensive care departments of the State Budgetary Healthcare Institution "SKIB" in Krasnodar and the State Budgetary Healthcare Institution "IB No 2" in Sochi were studied: group 1 - 31 people with influenza AH1N1pdm09 (21 people died - subgroup 1A;10 people survived - subgroup 1B) and group 2 - 50 people with COVID-19 (29 patients died - subgroup 2A;21 people survived - subgroup 2B). All patients developed hypoxemic ARF. All patients received step-by-step tactics of respiratory support, starting with oxygen therapy and ending with the use of "traditional" mechanical ventilation. Continuous variables were compared in subgroups of deceased and surviving patients for both nosologies at the stages: hospital admission;registration of hypoxemia and the use of various methods of respiratory therapy;development of multiple organ dysfunctions. With regard to the criteria for which a statistically significant difference was found (p < 0.05), we calculated a simple correlation, the relative risk of an event (RR [CI 25-75%]), the cut-off point, which corresponded to the best combination of sensitivity and specificity. Results. Risk factors for death of patients with influenza AH1N1pdm09 on mechanical ventilation: admission to the hospital later than the 8th day of illness;the fact of transfer from another hospital;leukocytosis >=10.0 x 109/l, granulocytosis >=5.5 x 109/l and LDH level >=700.0 U/l at admission;transfer of patients to mechanical ventilation on the 9th day of illness and later;SOFA score >=8;the need for pressor amines and replacement of kidney function. Predictors of poor outcome in ventilated COVID-19 patients: platelet count <=210 x 109/L on admission;the duration of oxygen therapy for more than 4.5 days;the use of HPNO and NIV as the 2nd step of RP for more than 2 days;transfer of patients to mechanical ventilation on the 14th day of illness and later;oxygenation index <=80;the need for pressors;SOFA score >=8. Conclusion. When comparing the identified predictors of death for patients with influenza and COVID-19 who needed mechanical ventilation, there are both some commonality and differences due to the peculiarities of the course of the disease. A step-by-step approach to the application of respiratory support methods is effective both in the case of patients with influenza AH1N1pdm09 and patients with COVID-19, provided that the respiratory support method used is consistent with the current state of the patient and his respiratory system, timely identification of markers of ineffectiveness of the respiratory support stage being carried out and determining the optimal moment escalation of respiratory therapy.Copyright © 2022, Dynasty Publishing House.

Towards gold standard care for peripartum women admitted to general intensive care units

Introduction: Critically-ill obstetric patients admitted to general intensive care units (ICU) are a rare and unique population for whom excellent care is essential to prevent devastating physical and psychological morbidity. Admissions are often unanticipated and can present challenges to obstetric and intensive care MDTs. 2018 Enhanced Maternal Care (EMC) Guidelines provide standards for caring for these women, and the 2022 Ockenden review exposed the association of peripartum ICU admission with undertreated psychological trauma and a desire for individualised debriefing [1,2]. We audited the care of obstetric admissions to general ICUs in our quaternary centre. We sought evidence of psychological morbidity to improve follow-up pathways in line with 2022 Ockenden actions. Method(s): Retrospective online case note review of maternity admissions to general ICUs between 1/1/2021-1/1/2022 compared to EMC audit standards. Exclusion criteria: <22/40 gestation, >6/52 postpartum and admissions to our level 2 labour ward high dependency unit. Result(s): 25 patients were admitted to general ICUs over 12 months. Median age was 35-39 years, mean parity was 1. The commonest indication was obstetric haemorrhage (n = 10). 15 of 25 patients required level 3 care, median length of stay was 1.5 days. Documentation of daily obstetric MDT ward round was variable, as was mother-baby contact. 0 of 25 women were seen in obstetric anaesthesia clinic after discharge, only 1 received outpatient ICU follow-up. 50% of postnatal admissions (n = 14) had documentation of significant psychological distress. In response a local checklist was developed with key colleagues to support collaborative working and standardise quality care. It includes automatic referral into obstetric anaesthesia clinic and access to a novel perinatal mental health service. Discussion(s): A peripartum admission to ICU is highly likely to be experienced as traumatic [2]. The incidence of obstetric ICU admissions may increase in the context of greater clinical complexity of the UK pregnant population and COVID-19, whilst the non-anaesthetic ICU workforce may have little obstetric training. Obstetric anaesthetists are therefore uniquely skilled to facilitate quality resuscitation and referral to ICU, but gold-standard holistic care extends beyond admission. We believe regular audit and dedicated local care pathways which incorporate proactive debriefing and psychological health can improve the care of this important group of women.Copyright © 2023 Elsevier Ltd

TL,DR - Improving handover through the use of an integrated electronic discharge proforma in neurocritical care

Introduction: Effective handover between treating clinical teams is an important part of communication in the care of patients leaving the intensive care environment.1 This can be even more vital in neurocritical care, where patients may be unable to communicate their own history due to neurological deficits and whose families are unable to visit due to COVID. These patients often have had complex neurosurgical interventions and ongoing complex MDT discussion due to the nature of their illness. Handover needs to represent this. Furthermore, as a specialist tertiary centre, many patients leave the unit as repatriations to other intensive care units. In these situations, it is even more important for good handover to contain the relevant and succinct information for ongoing care. Objective(s): We aim to improve the quality of handover from the intensive care team to ward teams at a specialist neurocritical care centre through the use of an electronic discharge proforma integrated into the electronic patient record (EpicCare Epic Systems Corporation). This is a system that has only recently been introduced locally and has required modification for the intensive care environment. Method(s): We performed a retrospective cohort study of documented transfer of care (TOC) summaries for patients entering the ICU in a month-long period. 67 patient admissions were identified as possible candidates with 11 cases excluded as not meeting criteria. The TOC summaries of suitable cases were compared to standards set by the Faculty of Intensive Care Medicine and Intensive Care Society and criteria tailored to the neuro-intensive care environment. Following this, we implemented a curated discharge proforma for all patients leaving intensive care. Through the use of smart lists and specific prompts, we aim to improve compliance with the guidelines and improve the quality of TOC. The project is currently ongoing and we aim to repeat the analysis in March 2022 to review if there has been improved compliance. Result(s): Compliance for the first round of discharges was variable. There was generally good quality information on the summary of stay of the patient (96%) and ongoing plan for the care of the patient (88%). However, documentation of the rehabilitation needs (32%), psychological needs (14%), communication needs (16%), safeguarding issues (4%), and resuscitation and escalation status of the patient was suboptimal (4%). Documentation of verbal handover to the parent team (25%) and critical care outreach team (45%) was mixed. Conclusion(s): Here we present the use of an electronic discharge proforma to improve the quality of handover in patients leaving the intensive care environment. While the study is ongoing, we show that currently local patient handover is often incomplete with a lack of detail in the TOC summary and poor verbal communication between teams. Through the use of this proforma, we aim to improve the quality of this handover and improve the continuity of care for patients leaving the neuro-intensive care unit.

The scandals of covid-19

Where clinicians once believed "there is no harm trying,” they realise that CPR offers little benefit to patients but brings significant risk to staff as they wait for the protective equipment that was promised in the UK and globally (doi:10.1136/bmj.m1423;doi:10.1136/bmj.m1367). Adding to the scandals of unpreparedness and lack of personal protective equipment is the scandal of testing. Germany's relatively low case fatality rate is helped by an "early and high level of testing” (doi:10.1136/bmj.m1395).

The BabySaver: Design of a New Device for Neonatal Resuscitation at Birth with Intact Placental Circulation.

The initial bedside care of premature babies with an intact cord has been shown to reduce mortality; there is evidence that resuscitation of term babies with an intact cord may also improve outcomes. This process has been facilitated by the development of bedside resuscitation surfaces. These new devices are unaffordable, however, in most of sub-Saharan Africa, where 42% of the world's 2.4 million annual newborn deaths occur. This paper describes the rationale and design of BabySaver, an innovative low-cost mobile resuscitation unit, which was developed iteratively over five years in a collaboration between the Sanyu Africa Research Institute (SAfRI) in Uganda and the University of Liverpool in the UK. The final BabySaver design comprises two compartments; a tray to provide a firm resuscitation surface, and a base to store resuscitation equipment. The design was formed while considering contextual factors, using the views of individual women from the community served by the local hospitals, medical staff, and skilled birth attendants in both Uganda and the UK.

COVID-19-specific adult basic life support guideline strategies for chiropractors and other healthcare providers to maximize the safety and efficacy of resuscitation: a commentary.

BACKGROUND: The emergence of an unprecedented novel severe acute respiratory syndrome coronavirus-2 (SARS-C0V-2), which causes the coronavirus disease 2019 (COVID-19) pandemic, has created new scenarios in basic life support (BLS) management. According to current evidence, SARS-CoV-2 can be transmitted airborne in aerosol particles during resuscitation. Research evidence found an alarming global increase in out-of-hospital cardiac arrests during the COVID-19 pandemic. Healthcare providers are legally obliged to respond to cardiac arrest as soon as possible. Chiropractors will likely encounter potential exercise-related and non-exercise-related cardiac emergencies at some point in their professional lives. They have a duty of care to respond to emergencies such as cardiac arrest. Chiropractors are increasingly involved in providing care, including emergency care, for athletes and spectators at sporting events. Also, exercise-related cardiac arrest in adult patients may occur during exercise testing or rehabilitation with exercise prescriptions in chiropractic and other healthcare settings. Little is known about the COVID-19 BLS guidelines for chiropractors. Knowledge of the current COVID-19-specific adult BLS guidelines is essential to developing an emergency response plan for the on-field and sideline management of exercise-related cardiac arrest and non-athletic, non-exercise-related cardiac arrest. MAIN TEXT: Seven peer-reviewed articles on the COVID-19-specific BLS guidelines, including two updates, were reviewed for this commentary. Responding to the COVID-19 pandemic, the national and international resuscitation organizations recommended interim COVID-19-specific BLS guidelines with precaution, resuscitation, and education strategies. BLS safety is paramount. A precautionary approach with the bare minimum of appropriate personal protective equipment for resuscitation is recommended. There was disagreement among the COVID-19 BLS guidelines on the level of personal protective equipment. All healthcare professionals should also undergo self-directed BLS e-learning and virtual skill e-training. The summarized COVID-19-specific adult BLS guideline strategies and protocols are tabled, respectively. CONCLUSIONS: This commentary provides a practical overview and highlights current evidence-based intervention strategies of the COVID-19-specific adult BLS guidelines that may help chiropractors and other healthcare providers reduce BLS-related exposures to SARS-CoV-2 and the risks of SARS-CoV-2 transmission and maximize the efficacy of resuscitation. This study is relevant to and impacts future COVID-19-related research in areas such as infection prevention and control.

Association between the COVID-19 pandemic in 2020 and out-of-hospital cardiac arrest outcomes and bystander resuscitation efforts for working-age individuals in Japan: a nationwide observational and epidemiological analysis.

BACKGROUND: Improving out-of-hospital cardiac arrest (OHCA) prognosis within the working-age population is important, but no studies have investigated the effects of COVID-19 pandemic specifically on the working-age population with OHCAs. We aimed to determine the association between the 2020 COVID-19 pandemic and OHCA outcomes and bystander resuscitation efforts among the working-age population. METHODS: Prospectively collected nationwide, population-based records concerning 166 538 working-age individuals (men, 20-68 years; women, 20-62 years) with OHCA between 2017 and 2020 were assessed. We compared characteristics and outcome differences of the arrests between three prepandemic years (2017-2019) and the pandemic year 2020. The primary outcome was neurologically favourable 1-month survival (cerebral performance category 1 or 2). Secondary outcomes were bystander cardiopulmonary resuscitation (BCPR), dispatcher-assisted instruction for cardiopulmonary resuscitation (DAI-CPR), bystander-provided defibrillation (public access defibrillation (PAD)) and 1-month survival. We examined variations in bystander resuscitation efforts and outcomes among pandemic phase and regional classifications. RESULTS: Among 149 300 OHCA cases, 1-month survival (2020, 11.2%; 2017-2019, 11.1% (crude OR (cOR) 1.00, 95% CI 0.97 to 1.05)) and 1-month neurologically favourable survival (7.3%-7.3% (cOR 1.00, 95% CI 0.96 to 1.05)) were unchanged; however, the neurologically favourable 1-month survival rate decreased in 12 of the most COVID-19-affected prefectures (7.2%-7.8% (cOR 0.90, 95% CI 0.85 to 0.96)), whereas it increased in 35 other prefectures (7.5%-6.6% (cOR 1.15, 95% CI 1.07 to 1.23)). Favourable outcomes decreased for OHCAs of presumed cardiac aetiology (10.3%-10.9% (cOR 0.94, 95% CI 0.90 to 0.99)) but increased for OHCAs of non-cardiac aetiology (2.5%-2.0% (cOR 1.27, 95% CI 1.12 to 1.44)). BCPR provision increased from 50.7% of arrests prepandemic to 52.3% (crude OR 1.07, 95% CI 1.04 to 1.09). Compared with 2017-2019, home-based OHCAs in 2020 increased (64.8% vs 62.3% (crude OR 1.12, 95% CI 1.09 to 1.14)), along with DAI-CPR attempts (59.5% vs 56.6% (cOR 1.13, 95% CI 1.10 to 1.15)) and multiple calls to determine a destination hospital (16.4% vs 14.5% (cOR 1.16, 95% CI 1.12 to 1.20)). PAD use decreased from 4.0% to 3.7% but only during the state of emergency period (7 April-24 May 2020) and in prefectures significantly affected by COVID-19. CONCLUSIONS: Reviewing automated external defibrillator (AED) locations and increasing BCPR through DAI-CPR may help prevent pandemic-associated decreases in survival rates for patients with cardiac OHCAs.

[Impact of the COVID-19 pandemic on basic resuscitation and success rate after sudden cardiac arrest]. / A COVID­19-pandémia hatása a hirtelen szívmegállást követo alapszintu újraélesztésre és annak sikerességére.

Since the onset of the coronavirus disease, infection-related mortality has been tracked worldwide and the number of deaths caused by the virus is counted daily. The coronavirus pandemic has not only transformed our daily life, but reorganized the whole healthcare system. In response to the increased demand for hospital admissions, leaders in different countries have implemented a number of emergency actions. The restructuring has had both direct and indirect negative effects on the epidemiology of sudden cardiac death, the willingness of lay rescuer to give cardiopulmonary resuscitation and the use of automated external defibrillators, but these negative effects vary widely across continents and countries. In order to protect lay people and health workers as well as to prevent the spread of the pandemic, the previous recommendations of the European Resuscitation Council on basic and advanced life support have undergone a few modifications.

Clinical features and acute management in adults

COVID-19 is a multisystem disease that requires holistic management. Most patients will experience mild symptoms including cough, fever and mild dyspnoea. A small proportion of patients will have severe manifestations including respiratory failure, ARDS and multiorgan failure. Extrapulmonary features are common and include gastrointestinal, thromboembolic, neurological, cardiac, renal, endocrine and dermatological manifestations. The care of COVID-19 patients requires close attention to these features. This includes respiratory support (such as supplemental oxygen, NIV and awake proning);fluid, electrolyte and nutrition management;prevention, detection and treatment of thrombotic events;management of diabetic complications;review of medications;appropriate use of antibiotics;and evidence-based use of therapeutic agents such as corticosteroids, antivirals such as remdesivir and other emerging therapies such as immunomodulating agents. Early planning for treatment escalation and decision making around the appropriateness of cardiopulmonary resuscitation are crucial as deterioration can be rapid. Prolonged symptoms occur in a minority of patients and longitudinal follow-up is required.Copyright © ERS 2021.

Hemoglobin-Based Oxygen Carriers: Brief History, Pharmacology and Design Strategies, Review of the Major Products in Clinical Trials, On-Going Studies, and Coagulation Concerns

Transfusion of erythrocytes (RBC) to treat acute or chronic anemia has significant drawbacks, given the risks of transfusion, volunteer donor requirements, limited supply with increasing demand, especially during a pandemic such as COVID-19, and erythrocytes are often unavailable in emergency situations or where blood is not an option. Significant research has been undertaken for almost 100 years to attempt to replicate the functions of RBCs with oxygen carriers/oxygen therapeutics based on hemoglobin. Oxygen carriers that have been evaluated are hemoglobin-based oxygen carriers (HBOCs). HBOCs utilize hemoglobin (Hb) to transport oxygen around the body. Blood transfusion may be critical therapy in hemorrhagic trauma, various pathologies both acute and chronic, and surgical interventions. It has some important goals: the first and most important is to recover oxygen delivery to organs, additionally, when restoration of circulating blood volume is achieved, maintenance of adequate blood pressure to ensure enough blood flow to deliver the oxygen to the microcirculation and resolving oxygen debt. This chapter will review the history of HBOCs, discuss how HBOCs have been designed and how developed HBOCs differ from each other based on their pharmacology and physiology, highlight all major products to undergo human trials including one extensively studied product approved for human use in two countries (Hemopure), introduce newer products still under development, and finally present translational and clinical trials studying whether or not certain HBOCs may cause coagulation issues. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Diagnostic performance of point-of-use ultrasound of resuscitation outcomes: A systematic review and meta-analysis of 3265 patients.

BACKGROUND: Echocardiography in the setting of resuscitation can provide information as to the cause of the cardiac arrest, as well as indicators of futility. This systematic review and meta-analysis were performed to determine the value of point-of-care ultrasonography (PoCUS) in the assessment of survival for adult patients with cardiac arrest. METHODS: This meta-analysis was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, Web of Science, Cochrane have been searched from databases inception until March 2nd 2021. The search was limited to adult patients with cardiac arrest and without publication dates or country restrictions. Papers were chosen if they met the required criteria relating to the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of this diagnostic technique concerning resuscitation outcomes. RESULTS: This systematic review identified 20 studies. Overall, for survival to hospital discharge, PoCUS was 6.2% sensitivity (95% confidence interval [CI] 4.7% to 8.0%) and 2.1% specific (95% CI 0.8-4.2%). PoCUS sensitivity and specificity for return of spontaneous circulation were 23.8% (95% CI 21.4-26.4%) and 50.7% (95% CI 45.8-55.7%) respectively, and for survival to admission 13.8% (95% CI 12.2-15.5%) and 20.1% (95% CI 16.2-24.3%), respectively. CONCLUSIONS: The results do not allow unambiguous recommendation of PoCUS as a predictor of resuscitation outcomes and further studies based on a large number of patients with full standardization of operators, their training and procedures performed were necessary.

The future of intensive care: the study of the microcirculation will help to guide our therapies.

The goal of hemodynamic resuscitation is to optimize the microcirculation of organs to meet their oxygen and metabolic needs. Clinicians are currently blind to what is happening in the microcirculation of organs, which prevents them from achieving an additional degree of individualization of the hemodynamic resuscitation at tissue level. Indeed, clinicians never know whether optimization of the microcirculation and tissue oxygenation is actually achieved after macrovascular hemodynamic optimization. The challenge for the future is to have noninvasive, easy-to-use equipment that allows reliable assessment and immediate quantitative analysis of the microcirculation at the bedside. There are different methods for assessing the microcirculation at the bedside; all have strengths and challenges. The use of automated analysis and the future possibility of introducing artificial intelligence into analysis software could eliminate observer bias and provide guidance on microvascular-targeted treatment options. In addition, to gain caregiver confidence and support for the need to monitor the microcirculation, it is necessary to demonstrate that incorporating microcirculation analysis into the reasoning guiding hemodynamic resuscitation prevents organ dysfunction and improves the outcome of critically ill patients.

New Onset Diabetes and Acute Pancreatitis- A Sequela of Long COVID?

Introduction: The association between worse COVID-19 outcomes and diabetes has been well-established in the literature. However, with more cases of new-onset diabetes and pancreatitis being reported with or after COVID-19 infection, it poses the question if there is a causal relationship between them. Case Description: 31 y/o female with COVID-19 infection 4-6 weeks ago with moderate symptoms (not requiring hospital admission or monoclonal ab), presented to ED with bandlike epigastric pain radiating to back, which is worsened with food, associated with nausea, vomiting, polyuria, and fatigue. Workup showed lipase 232, AST 180, ALT 256. Blood glucose was 281 and HbA1c was 12. CT A/P showed post cholecystectomy status, normal pancreas with mesenteric adenitis. MRCP showed hepatic steatosis with trace fluid around the pancreas s/o inflammation, and no evidence of choledocholithiasis or biliary dilatation. She denied alcohol use and autoimmune workup for pancreatitis was unremarkable. Islet cell antibodies were negative. The patient improved with fluid resuscitation and was discharged home on insulin with plans to transition to oral agents outpatient. Discussion(s): Long COVID is defined as a range of conditions or symptoms in patients recovering from COVID-19, lasting beyond 4 weeks after infection. A retrospective cohort study showed increased new-onset diabetes incidence in patients after COVID-19. This was redemonstrated in a systematic review and meta-analysis that showed a 14.4% increased proportion of new diagnoses of diabetes in patients hospitalized with COVID-19. Possible pathophysiology that have been attributed to this include undiagnosed pre-existing diabetes, hyperglycemia secondary to acute illness and stress from increased inflammatory markers during the cytokine storm, the effect of viral infections on the pancreas, and concurrent steroid use in patients with severe respiratory disease. The binding of SARS-CoV-2 to ACE2 receptors is thought to the other mechanism by which COVID can cause pancreatitis and hyperglycemia. Study showed increased lipase and amylase levels in patients with COVID and the increase in serum levels was proportional to the severity of the disease. Patients who died due to COVID-19 were also found to have degeneration of the islet cells. While, several studies have showed new onset diabetes and pancreatitis during an active COVID infections, we need larger cohort studies to comment on its true association or causation, especially in patients with long COVID symptoms. As more cases of new onset diabetes and pancreatitis with COVID-19 are being reported, there may be a need for more frequent blood sugar monitoring during the recovery phase of COVID-19.Copyright © 2023

Rise in Out-of-Hospital Cardiac Arrest Cases in Chicago in 2020

Background: Italy, France and New York City have reported an increase in out-of-hospital cardiac arrest (OHCA) incidence during the COVID-19 pandemic. The purpose of our study was to assess the effect of COVID-19 on OHCA cases in Chicago. Method(s): Cardiac Arrest Registry to Enhance Survival (CARES) database was used. Bivariate analysis was conducted to assess changes in demographic and other characteristics. We excluded the cases that occurred in a healthcare facility or a nursing home. We compared the cases reported in 2020 to 2019 (and prior years). ArcGIS was used to geocode incident addresses and to show the temporal distribution by community areas. Bivariate analysis was done using chi-square tests. Result(s): A total of 3221 OHCA cases were reported in Chicago in 2020, which is 31.5% higher than those reported in 2019 (n=2450 cases). This increase was higher than what has been noticed historically (for instance, the increase from 2018 to 2019 was only 17%). There was an increase in Hispanic OHCA cases (17.3% in 2020 vs. 13.5% in 2019, p<0.01) but a decrease in White cases (20.5% vs. 23.1%). The cases in 2020 were less likely to be reported at public location (22% vs. 26%, p<0.001) or have shockable rhythm (10% vs. 13%, p=0.0002). There was a marked increase in those that were declared dead in the field in 2020 (37% vs. 27%, p<0.001). However, there were no statistically significant differences in age distribution, gender, witnessed arrest (49% vs. 51%, p=0.07) or bystander cardiopulmonary resuscitation (BCPR) (23% vs. 22%, p=0.3). Conclusion(s): A better understanding of the causes of the excess cardiac arrest numbers will be important to help plan and better prepare for future public health interventions. The effect of COVID19 on OHCA survival needs to be examined further in future studies.

Reasons for the termination of resuscitation in out-of-hospital cardiac arrests before and after the COVID-19 pandemic in Korea

The incidence of out-of-hospital cardiac arrest (OHCA) gradually increased during the coronavirus disease 2019 (COVID-19) pandemic, and the number of cases requiring termination of resuscitation (TOR) also rose. This study aimed to analyze the reasons for TOR of OHCA cases over 2 years (2019–2020). This retrospective observational study was conducted using data gathered from prehospital emergency medical service (EMS) care reports generated in Seoul between 01 January 2019, and 31 December 2020. We included OHCA cases reported to the EMS system in this study. Patients who experienced cardiac arrest for a non-medical cause and received cardiopulmonary resuscitation (CPR) from EMS paramedics at the scene were excluded. The variables of demographics and comorbidities, arrest location, identity of the bystander, cause of cardiac arrest, first monitored electrocardiographic (ECG) rhythm, and reason for TOR were investigated. We compared data for 1 year before and after the start of the COVID19 pandemic. A total of 10,872 OHCAs with TOR were included in this study;of these, 6238 cardiac arrest cases were terminated without resuscitation attempts during the COVID-19 period compared to 4634 during the pre-COVID-19 period. During the COVID-19 period, the proportion of women in the total population decreased, while the median age increased (p < 0.001). Patients with comorbidities, the frequency of asystole rhythm at first monitoring, and the number of witnessed cardiac arrests significantly increased (p < 0.001). The proportion of TOR cases due to decisions made by a medical director and refusal of CPR by family members also significantly increased, while that due to clear evidence of death decreased (p < 0.001). In conclusion, there was a significant change in the reason for TOR before and after the COVID-19 pandemic in Korea.
