Prevalence of multidrug-resistant Gram-negative bacteria from blood cultures and rapid detection of beta-lactamase-encoding genes by multiplex PCR assay

Introduction This study aimed to determine the prevalence of multidrug-resistant Gram-negative bacteria (GNB) from blood cultures in a tertiary-care hospital and the multiplex PCR assay's ability to detect resistance genes. Methods A total of 388 GNB isolates obtained from hospitalized patients between November 2019 and November 2021 were included in the study. Antimicrobial susceptibility testing was done by VITEK 2 system and broth microdilution method. Beta-lactamase-encoding genes were detected by multiplex PCR assays, BioFire-Blood Culture Identification 2 (BCID2) panel (bioMerieux, France). Extended-spectrum beta-lactamases (ESBLs) were detected phenotypically with VITEK AST-GN71 card (bioMerieux, France). The isolates of GNB were classified into multidrug-resistant, extensively-drug-resistant, and pandrug-resistant categories, and their prevalence and distribution in different wards, including coronavirus diseases 2019 (COVID-19) intensive care units (ICU), were calculated. Results Results revealed that all isolates of Acinetobacter baumannii and Pseudomonas aeruginosa were multidrug-resistant as well as 91.6% of Enterobacter cloacae, 80.6% of Proteus mirabilis, and 76.1% of Klebsiella pneumoniae, respectively. In fermentative bacteria, blaOXA-48-like (58.1%), blaNDM (16.1%), blaKPC (9.7%) and blaVIM (6.5%) genes were detected. More than half of Enterobacter cloacae (58.3%) and Klebsiella pneumoniae (53.7%) produced ESBLs. Among non-fermenters, the blaNDM gene was carried by 55% of Pseudomonas aeruginosa and 19.5% of Acinetobacter baumannii. In the COVID-19 ICU, Acinetobacter baumannii was the most common isolate (86.1%). Conclusions This study revealed high proportions of multidrug-resistant blood isolates and various underlying resistance genes in Gram-negative strains. The BCID2 panel seems to be helpful for the detection of the most prevalent resistance genes of fermentative bacteria.Copyright © GERMS 2022.

Intensive Care Consultant: Superhero or normal human being but more capable!

Submission content Introduction: Intensive care medicine has become an admired, loved, hated, and definitely more interesting Specialty due to a special situation (COVID-19) that exposed the training process to numerous criticisms, positives, and negatives, and this is how I believe we could improve our beloved world. Proposal: 1. Ideal training program from medical school to Certificate of Completion of Training (CCT): * Medical school: In their last year they should do more than 1 week in the Intensive Care Unit (ICU) * Stage 1: there should be a core surgical training of at least 6 months * Stage 2: there should be a rotation on Psychiatry of at least 4 weeks with on calls in ICU and 2 weeks in Palliative Care * Stage 3: acting as a consultant for the last six months on ST7 with backup from a formal consultant, and * Surgical training should be included in the possible dual or triple CCT 2. How would we be assessed? I agree with the Faculty of Intensive Care Medicine (FICM) staging program assessment, with some modifications: * As ST7 the trainee should act as a consultant with back support at least 50% of the stage and need to be evaluated by a Multi-Source Feedback (MSF). * Clinical Fellows should have a consultant as a Certificate of Eligibility for Specialist Registration (CESR) guide who establishes the equivalent stage of training supporting them and assessing them under the same model. * Changing the way, the General Medical Council (GMC) conducts the CESR application and making it really equivalent to the ICM training with the FFICM curriculum. 3. What do we need to be taught? * Hot topics for ICU (academic), * Overseas talks to share experiences, * Ultrasound (FUSIC), * Wellbeing strategies, * Leadership training * Psychiatric and physiological effects post ICU for patients and staff, * The administrative and political model of the National Health Service (NHS), and * Communication skills to establish excellent relationships with the other specialties. 4. What would our working life look like? * Normal day: 8 am to 3 pm * Midday shift: 1 pm to 8:30 pm * Night shift: 8 pm to 8:30 am * A rolling rota of 12 weeks with 2 weekends during this time 5. How would you produce Intensive Care Medicine (ICM) Consultants of the future who both love their job and their life: * Starting with less intense shifts, * More cordial relationships between the teams, * Supporting ICM trainees and Fellows going through their CESR pathway, * Making the training more attractive to either male-female doctors getting them involved in as many different specialties as ICM can cover, Conclusion(s): Having full-time ICM Consultants should be welcome in all ICUs in the country, which is not at the moment. This will definitely attract a lot of excellent doctors who are 100% focused on ICM.

A case series of diabetic ketoacidosis associated with SGLT2 inhibitors

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are increasingly initiated as treatment for type 2 diabetes due to favourable cardiorenal characteristics. However, studies have identified an increased risk of diabetic ketoacidosis (DKA). We carried out a retrospective, case-based study at East and North Herts NHS Trust between February 2018 and December 2020. Fifteen cases of SGLT2i associated DKA were identified in people with presumed type 2 diabetes;33.3% were classed as euglycaemic DKA with a blood glucose of <11mmol/L. All cases were associated with a significant precipitating factor including diarrhoea, vomiting, reduced oral intake and sepsis. One case was related to COVID-19. Two people were subsequently found to have raised islet autoantibodies suggesting type 1 diabetes or latent autoimmune diabetes in adults. It is important that awareness of SGLT2i associated DKA is raised among users and health care practitioners, including the recognition of euglycaemic DKA. Sick day rules should be emphasised and reiterated at clinical encounters. Non-specialists in primary care, oncology and in perioperative settings should be empowered to advocate for temporary withdrawal and there should be readier access to blood ketone monitoring when required. When SGLT2i associated DKA occurs, due consideration should be given to evaluate the diabetes classification and investigate the circumstances of the event.

Clinical Characteristics of Patients with Sars-Cov-2 Omicron Variant and COVID-19 Vaccination with Clinical Outcome Findings in Shanghai, China: A Single Center, Retrospective, Observational Study

Objectives: This study aimed to determine disease severity, clinical features, clinical outcome in hospitalized patients with the Omicron variant and evaluate the effectiveness of one-dose, two-dose, and three-dose inactivated vaccines in reducing viral loads, disease course, ICU admissions and severe diseases. Method(s): Retrospective cohort analysis was performed on 5,170 adult patients (>=18 years) identified as severe acute respiratory syndrome coronavirus 2 positive with Reverse Transcription Polymerase Chain Reaction admitted at Shanghai Medical Center for Gerontology between March 2022 and June 2022. COVID-19 vaccination effectiveness was assessed using logistic regression models evaluating the association between the risk of vaccination and clinical outcomes, adjusting for confounders. Result(s): Among 5,170 enrolled patients, the median age was 53 years, and 2,861 (55.3%) were male. 71.0% were mild COVID-19 cases, and cough (1,137 [22.0%]), fever (592 [11.5%]), sore throat (510 [9.9%]), and fatigue (334 [6.5%]) were the most common symptoms on the patient's first admission. Ct values increased generally over time and 27.1% patients experienced a high viral load (Ct value< 20) during their stay. 105(2.0%) of these patients were transferred to the intensive care unit after admission. 97.1% patients were cured or showed an improvement in symptoms and 0.9% died in hospital. The median length of hospital stay was 8.7+/-4.5 days. In multivariate logistic analysis, booster vaccination can significantly reduce ICU admissions and decrease the severity of COVID-19 outcome when compared with less doses of vaccine (OR=0.75, 95%CI, 0.62-0.91, P<=0.005;OR=0.99, 95%CI, 0.99-1.00, p<0.001). Conclusion(s): In summary, the most of patients who contracted SARSCoV-2 omicron variant had mild clinical features and patients with vaccination took less time to lower viral loads. As the COVID-19 pandemic progressed, an older and less vaccinated population was associated with higher risk for ICU admission and severe disease.Copyright © 2023

Creating a smart classroom on intensive care using assisted reality technology

Introduction: Medical students receive relatively little exposure to intensive care medicine throughout their undergraduate training in comparison to other specialties. The COVID-19 pandemic further hindered students' exposure with entrance to intensive care units (ICU) limited to conserve personal protective equipment (PPE) and reduce the risk of virus spread. To address this problem, this study explored the use of assisted reality technology to create a smart classroom whereby medical students can experience intensive care medicine with the COVID-19 risks mitigated. There is existing literature describing the use of live streaming ward rounds using wearable technology to teach medical students, however, we believe this is the first time assisted reality technology has been harnessed to develop a teaching curriculum on intensive care.1 Objectives: This study aimed to assess the feasibility of using a wearable headset with assisted reality technology to live stream intensive care teaching to remotely based medical students. Method(s): Three intensive care teaching sessions were live streamed to three groups of medical students using the AMA XpertEye wearable glasses. The teaching session focused on the intensive care bed space and equipment as well as the assessment of a critically unwell intensive care patient. Two educators were required to facilitate the optimum learning environment. One educator wore the assisted reality technology glasses on the ICU whilst the other educator remained with the students to facilitate group discussion. The educators had the means to communicate via inbuilt technology on the glasses. Feedback from students was collected using the evaluation of technology-enhanced learning materials (ETELM).2 Results: The response rate for the ETELM survey was 100%. Students strongly agreed that the session was well organised, relevant and that the navigation of technology-based components was logical and efficient. 'There was a strong instructor presence and personal touch to the session' returned the strongest positive response. 'This session will change my practice' received the most varied response from students, potentially due to their stage in undergraduate training and distance from actual clinical practice. Students strongly disagreed that their learning was affected by technology issues. Educators reported problems with securing a patient appropriate to be involved alongside the busy clinical demands of the ICU. Facilitation by trained educators was crucial to ensure the teaching sessions were high quality. Conclusion(s): The use of smart classrooms on intensive care using assisted reality technology was very well received by medical students and educators. The main limitations included the necessity to balance the delivery of teaching alongside the clinical demands of the unit, however this is arguably the case with most forms of clinical teaching. There is the potential to continue using smart classrooms in the post-pandemic period, as they provide an open and safe platform for students to explore intensive care medicine and to ask questions that they may feel less able to raise in the busy clinical environment.

Salt steps and sugar checks - Making arterial line use safer in our trust

Introduction: Arterial lines are used within our intensive care unit to allow invasive blood pressure monitoring and regular blood gas analysis. Inadvertent use of dextrose containing fluids in the flush have been associated with falsely high glucose readings. When these are acted on with insulin, it can cause devastating hypoglycaemic brain injury. There have been a number of deaths and other incidents relating to the wrong fluid being used in arterial line set up reported within the UK in recent years. In 2014 the AAGBI released a safety guideline on the use of arterial lines specifically to reduce to the risk of hypoglycaemic brain injury. Objective(s): Our objective was to ensure that 100% of arterial lines in use within Royal Victoria Hospital's intensive care unit were compliant with our trust policy on the management of arterial lines. Method(s): We audited our intensive care unit's compliance with our trust policy and found that we were 80% compliant. We formed a multi-disciplinary arterial line working group in order to tackle the problem. Our quality improvement project consisted of two main approaches: 1. To educate staff on how to manage arterial lines correctly. We divided the management of arterial lines into S.A.L.T steps (a 7 step bundle on "Setting up an Arterial Line Transducer") and SUGAR checks ( a series of red flag moments to prompt staff to review the patient prior to starting or increasing insulin administration).We developed educational posters for key areas in ICU and presented our findings at departmental meetings. 2. To change the system, in order to make it easier to do the right thing. We developed a Universal Adult Arterial Pack (UAAP) containing key components in the setup of an arterial line. This also included aide memoires for the S.A.L.T steps and SUGAR checks. In order to measure the effect of these changes, we: 1. Audited compliance on a regular basis. 2. Monitored serious bundle breaches ( for example no label, wrong fluid used) 3. Assessed usage of the UAAP. Result(s): 1. Bundle compliance improved during the first half of 2021, however then reduced in the second half with the number of serious bundle breaches increasing. This coincided with COVID surge 4 - associated with reduced nursing ratios and staff redeployment. 2. UAAP usage increased throughout the project, from an average of 6 to 9 per day. 86% of staff found the packs useful and 85% thought that they reduced the potential for error. Conclusion(s): The presence of a policy does not ensure that staff will know about it or adhere to it. Although we have not yet achieved our target of 100% compliance, we have seen evidence of how our project has the potential to do so in the near future. We aim to roll out our new e-learning module for staff education, manufacture our UAAP on a bigger scale, and disseminate the project to other departments within the trust.

Re-humanisation, Recognising the person behind the patient

Submission content Introduction: At the end of a particularly hectic night shift on the intensive care unit (ICU) I found myself sitting in the relatives' room with the mother and aunt of a young patient, listening to their stories of her hopes and aspirations as she grew up. She had been diagnosed with lymphoma aged 14 and received a bone marrow transplant from her younger sister. Fighting through treatment cycles interposed with school studies, she eventually achieved remission and a portfolio of A-levels. Acceptance into university marked the start of a new era, away from her cancer label, where she studied forensic science and took up netball. Halfway through her first year she relapsed. Main body: When I met this bright, ambitious 20-year-old, none of this history was conveyed. She had been admitted to ICU overnight and rapidly intubated for type-1 respiratory failure. The notes contained a clinical list of her various diagnoses and treatments, with dates but no sense of the context. Rules regarding visitation meant her family were not allowed onto the unit, with next-of-kin updates carried out by designated non-ICU consultants to reduce pressures on ICU staff. No photos or personal items surrounded her bedside, nothing to signify a life outside of hospital. She remained in a medically-induced coma from admission onwards, while various organ systems faltered and failed in turn. Sitting in that relatives' room I had the uncomfortable realisation that I barely saw this girl as a person. Having looked after her for some weeks, I could list the positive microbiology samples and antibiotic choices, the trends in noradrenaline requirements and ventilatory settings. I had recognised the appropriate point in her clinical decline to call the family in before it was too late, without recognising anything about the person they knew and loved. She died hours later, with her mother singing 'Somewhere Over the Rainbow' at her bedside. Poignant as this was, the concept of this patient as more than her unfortunate diagnosis and level of organ failure had not entered my consciousness. Perhaps a coping mechanism, but dehumanisation none-the-less. Conclusion(s): Striking a balance between emotional investment and detachment is of course vital when working in a clinical environment like the ICU, where trauma is commonplace and worst-case-scenarios have a habit of playing out. At the start of my medical career, I assumed I would need to consciously take a step back, that I would struggle to switch off from the emotional aspects of Medicine. However, forgetting the person behind the patient became all too easy during the peaks of Covid-19, where relatives were barred and communication out-sourced. While this level of detachment may be understandable and necessary to an extent, the potential for this attitude to contribute to the already dehumanising experience of ICU patients should not be ignored. I always thought I was more interested in people and their stories than I was in medical science;this experience reminded me of that, and of the richness you lose out on when those stories are forgotten.

AI and ICU Monitoring on the Wake of the COVID-19 Pandemic

The Intensive Care Unit (ICU) is a paradigmatic example of the potential reach of data-centred knowledge discovery. This is because the contemporary ICU heavily depends on medical devices for patient monitoring through electronic data acquisition. This poses a unique opportunity for multivariate data analysis to support evidence-based medicine (EBM), particularly in the form of Artificial Intelligence (AI) approaches. The COVID-19 pandemic has tested the limits of critical care management, often overwhelming ICUs. In this brief chapter, we sketch the role of AI, especially in the form of Machine Learning (ML), at the ICU and discuss what can it offer to address COVID-19 disruption in this environment. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

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 Effect of CRP/Albumin, Platelet/Lymphocyte, SOFA, and APACHE II in Predicting Mortality in Covid-19 Patients in Intensive Care Unit

Objectives: It is important to predict the prognosis during hospital admission of Covid-19 patients. The purpose of this study was to see how CRP/ Albumin (CAR) and Platelet/Lymphocyte (PLR) ratios, obtained from patients in the intensive care unit (ICU) within the first 24 hours of their hospitalization with a Covid-19 diagnosis, predictmortality and how they correlated with acute physiology and chronic health evaluation (APACHE II) and sequential organ failure assessment (SOFA). Method(s): Using hospital records, records of 83 patients hospitalized in the ICU with a diagnosis of Covid-19 between 11.03.2020 and 01.01.2021 were retrospectively analyzed . Patients were divided into two groups discharged (Group I) and exits (ex) group (Group II). CAR and PLR were recorded during the first 24 hours of ICU admission, and APACHE II and SOFA scores were computed. The calculated CAR and PLR were correlated with APACHE II and SOFA scores and their association with mortality was investigated. Result(s): SOFA, APACHE II, PLO, and age were higher, and albumin was lower in patients in the mortal course (p<0.05). ROC analysis revealed that APACHE II and SOFA scores could be employed to estimate mortality. Conclusion(s): We believe that APACHE II and SOFA scores can be used to predict mortality in patients admitted to the ICU due to Covid-19, whereas CRP/Albumin and Platelet/Lymphocyte ratios cannot.

Direct costs of hospital care according to coinfection in adult COVID-19 patients

Objective: To estimate the direct costs of hospital care according to coinfection in adult COVID-19 patients. Material(s) and Method(s): A retrospective follow-up study of adult patients hospitalized for COVID-19 between March and August 2020 at the San Vicente Foundation Hospitals (Medellin and Rionegro, Colombia). Patients whose diagnosis of SARS-Cov2 pneumonia was confirmed by RT-PCR test were included. Death from any cause and length of stay were considered outcome variables. Costs were estimated in 20 20 US dollars. Result(s): 365 patients with an average age of 60 years (IQR: 46-71), 40% female, were analyzed. 60.5% required an Intensive Care Unit (ICU). All-cause mortality was 2.87 per 100 patient-days. Patients admitted to the ICU who developed coinfection had an average length of stay of 27.8 days (SD:17.1) and an average cost of $23,935.7 (SD: $16,808.2);patients admitted to the ICU who did not develop a coinfection had an average length of stay of 14.7 days (SD:8.6) and an average cost of $9,968.5 (SD: $8,054.0). Conclusion(s): A high percentage of patients required intensive care, and there was a high mortality due to COVID-19. In addition, a higher cost of care was observed for those patients who developed coinfection and were admitted to ICU.Copyright © 2023 Asociacion Colombiana de Infectologia. All rights reserved.

Ethnic, racial and migrant inequalities in respiratory health

Disparities in the incidence, prevalence, and morbidity and mortality rates of many respiratory diseases are evident among ethnic groups. Biological, cultural and environmental factors related to ethnicity can all contribute to the differences in respiratory health observed among ethnic minority groups, but the inequalities observed are most commonly due to lower socioeconomic position. People who migrate within a country or across an international border may experience an improvement in respiratory health associated with improvements in socioeconomic position. However, migrants may also experience worse health outcomes in destination countries, as they are faced by barriers in language and culture, discrimination, exclusion and limited access to health services. While some high-quality studies investigating ethnicity and respiratory health are available, further research into ethnic differences is needed. Improving the recording of ethnicity in health records, addressing barriers to accessing respiratory healthcare and improving cultural literacy more generally are some of the ways that inequalities can be tackled.Copyright © ERS 2023.

Using the "omnicell" automatic drug dispensing cabinet to monitor sedative drugs in a critical care unit

Introduction: Automatic drug dispensers are now widely used in critical care.1-2 They can provide information about dispensed drugs. Good practice in sedation restricts the use of sedatives and titrates doses to defined responses.3-4 Objectives: To extract drug dispenser issuing records for sedatives and link these to patient records to evaluate sedative use. Method(s): in October 2019, we introduced two Omnicell XT automated dispensing cabinets (Omnicell inc. CA, USA) into a 42 bedded general/neurological unit. ICNARC (Intensive care national audit and research centre) and CCMDS (Critical care minimum data set) data was collected using the Ward Watcher program. Dispenser issuing records for alfentanil, propofol and midazolam were obtained as Excel files for 13 months from January 2020. Output time stamps were converted to dates and times. Outputs were linked to outputs of the ICNARC and CCMDS records for the patients that the drugs were issued to. All the outputs had patients identified by their unique hospital numbers. These were used in Excel "power queries" to produce a spread sheet with a single row per patient. Multiple admissions used the first diagnosis, the final outcome and the total length of stay. The total dose of sedatives was calculated from ampoule dose and number. The duration of treatment was calculated from the first and last issues of the drug. ICNARC codes were used to identify the primary system in the admission diagnostic code and those patients admitted for COVID-19. Variables were compared using Chi Squared, Mann-Whitney U and Kruskal Wallis Tests. The significance of associations was established using Spearman's Rho. Linear regression was used to define relationships more clearly. Result(s): Table one summarises the patient characteristics with respect to all admissions during the study period and for patients who had had the studied drugs issued to them. Midazolam was used in fewer patients, they were more likely to be male, heavier (p>0001) and to die than patients receiving Propofol or Alfentanil (p>0.001). With respect to diagnostic groups, all the sedatives, particularly Midazolam (p<0.001), were more likely to be used in patients with COVID-19. The relationship between the dose of sedative drugs and patient age and weight was explored using the dose per advanced respiratory day. All three drugs had a significant but weak negative relationship with age, lower doses being given to older people (Propofol r2 = 0.02, p=0.01. Alfentanil r2 = 0.04, p=0.00. Midazolam r2 = 0.07, p=0.00.). There was also a weak but significant relationship between increasing dose of Propofol with patient weight (r2 = 0.02, p=0.01), but there was no relation between weight and doses of the other drugs. Conclusion(s): Information from automatic drug dispensers can be interpreted and combined with other datasets to produce clinically relevant information. The limited weak relationships between drug dose and age and weight suggests that sedative drugs could have been better titrated to response.

Evaluation of Microbiological Culture and Antibiogram of the Patient with Corneal Ulcer due to Exposure Keratitis in the Intensive Care Unit in Sina Farshchian Hospital (2019-2020)

Background: Since patients admitted to the intensive care unit have a compromised im-mune system and are more prone to infection than other patients, timely diagnosis and treatment of corneal ulcers among this group of patients can prevent vision loss. Therefore, it is necessary to treat eye infections and corneal ulcers promptly and economize prohibitive costs. Objective(s): Appropriate treatment with the most effective antibiotic before the answer is available to prevent corneal ulcer complications and blindness. Method(s): This study was conducted from November 2019 to November 2020 and after approval by the ethics committee of Hamedan University of Medical Sciences with the code of ethics: IR.UMSHA.REC.1398.716. First, the corneal secretions of 121 patients admitted to the intensive care unit of Sina Hospital are prepared by an ophthalmologist (after anesthetizing the cornea with tetra-caine drops and sterile swabs) and culture in four growth mediums (blood agar, chocolate agar, thio-glycolate, and EMB). Microbial cultures are examined after 48 hours and a fungal culture is examined one week later. Disc diffusions are placed in positive microbial cultures. Antibiotic susceptibility or resistance of the antibiogram was recorded. Other demographic data, including patients' age and sex, are extracted from ICU files. Also, test results and patient identifications are recorded in a checklist designed for this purpose. Result(s): Of all the antibiotics used against common bacteria, vancomycin (84%), colistin (80.43%), cefazolin (80%), and levofloxacin (60%) had the highest sensitivity and gentamicin (93.75%), ceftazidime (86.42%) Erythromycin (85%) had the highest resistance against isolated bacteria. Conclusion(s): The data obtained from this study showed that the most common microorganisms in the age group under the age of 30 years were Acinetobacter Baumannii, in the group of 30-60 years old was Klebsiella pneumonia, and age group over 61 years old was Staphylococcus aureus, and the most sensitive antibiotics in the age group under 30 years were vancomycin and levofloxacin and the age group30-60 were colistin and vancomycin and in the age group over 61 years were vancomycin and cefazolin.Copyright © 2023 Bentham Science Publishers.

Medical intensivist directed VV ECMO cannulation for the facilitation of tracheostomy in a patient with severe tracheal stenosis: A case report

Objectives: We present a case report of medical intensivist driven ECMO program using ECMO as a pre-procedural tool to maintain oxygenation in a patient with critical tracheal stenosis during tracheostomy placement. Method(s): VV ECMO is primarily used to support patients when mechanical ventilation is unable to provide adequate gas exchange. Alternatively, it has been used pre-procedurally when intubation is required in anticipation of a difficult airway. Described here is the first intensivist preformed awake VV ECMO cannulation to facilitate tracheostomy in a patient with severe tracheal stenosis. Result(s): The patient is a 41-year-old female with the relevant background of COVID19 pneumonia status post tracheostomy and subsequently decannulated after prolonged intubation and ICU stay. As a result, the patient developed symptomatic tracheal stenosis and presented two years after her ICU stay for scheduled bronchoscopy and balloon dilation. However, the patient developed worsening stridor and shortness of breath requiring heliox and BPAP. After multidisciplinary discussion between the critical care team ENT teams, the decision was made to cannulate for VV ECMO as a pre-procedural maneuver to allow for oxygenation during open tracheostomy in the OR. Dexmedetomidine and local anesthesia were used for the procedure with the patient sitting at 30 degrees on non-invasive ventilation and heliox. The patient was cannulated with a 21F right internal jugular return cannula and 25F right common femoral drainage cannula by medical intensivists in the intensive care unit using ultrasound guidance. The patient went for operative tracheostomy the next day and was subsequently decannulated from ECMO the following day without complication. She was discharged home on trach collar. Conclusion(s): Intensivist performed ECMO cannulation has been shown to be safe and effective. We anticipate the indications and use will continue to expand. This case is an example that intensivist driven preprocedural ECMO is a viable extension of that practice.

Totally Percutaneus Veno-Venous ECMO Therapy for COVID 19 Patients. Bridge to Recovery or Lung Transplantation?

Objective: Multiple major health organisations recommend the use of extracorporeal membrane oxygenation (ECMO) support for COVID-19-related acute hypoxaemic respiratory failure. Method(s): From march 2020 to november 2021 we done 108 veno-venous ECMO therapies. 35 patients required implantation immediately in intensive care unit in place of call by mobile ECMO team. Depend from distance of call it was used medical ambulance, rescue helicopter or medical plane. Result(s): In the first analyzed period (March-December 2020), 90-day mortality was 41%. 8 (7.6%) patients were discharged from the Intensive Care Unit. The remaining 3 (4.2%) were discharged home. 7 patients (6.6%) had both lung transplants. 7 patients (6.6%) required conversion to VV-A ECMO therapy due to the development of acute heart failure. Conclusion(s): In the analyzed period of March-December 2020, the mortality was 41%. As a result, the lower effect of regression of consolidation and inflammatory lesions of lung tissue indicates that ECMO therapy remains the treatment method in high-risk patients as a bridge therapy to lung transplantation.

Maternal outcome of pregnant and postpartum women admitted to intensive care unit due to COVID-19 infection: A retrospective study

Background: Previous data of COVID-19 indicates the obstetric population to be at specified risk for critical COVID-19 disease. In this study patient records were analyzed to gain information about the connection between pregnancy and intensive care treatment due to COVID-19 infection. Material(s) and Method(s): A retrospective study of all COVID-19 positive obstetric patients in Helsinki University Hospital admitted to intensive care units (ICU) from the beginning of March 2020 until the end of January 2022. Primary outcome is to compare the number of COVID-19 positive obstetric ICU patients to all ICU patients. Secondary outcomes are maternal 30-day survival and immediate neonatal survival. The study also looks at number of variables related to pregnancy and ICU treatment including age, previous medical history, BMI and COVID-19 vaccination status, obstetric data (i.e., gestational weeks, obstetric complications and route of delivery), treatments received at the ICU and length of ICU and hospital stay. Result(s): In total 20 obstetric patients with COVID-19 were admitted to the intensive care unit during the observation period. This is 2,3% of all COVID-19 patients and 27,4% of all 18-45 years old female COVID-19 patients treated in the intensive care unit in Helsinki University Hospital. Maternal 30-day survival was 95% (n = 19). Immediate neonatal survival was 95% (n = 19). Conclusion(s): Pregnancy increased the risk of ICU admission for COVID-19 infection. These results align with previous studies reporting pregnancy as a risk for critical COVID-19 infection and ICU admission. The 30-day survival was high compared to all ICU patients.

Improving Outcomes in Oesophagectomy Patients

Introduction: Aberdeen Royal Infirmary is a low volume centre carrying out approximately 13 oesophagectomies per annum. Due to minimal exposure to post-operative oesophagectomy patients, staff had low perceived confidence in their management within the Intensive Care Unit (ICU). After an initial pause due to the COVID-19 pandemic, oesophagectomy service provision restarted in June 2020. Prior to this project, no standardised care pathway existed for post-operative oesophagectomy patients. A protocol driven management pathway was implemented within the ICU setting in October 2020. Objective(s): 1. Standardise the first 5 days of post-operative care for oesophagectamies 2. Improve 30 day mortality rate 3. Reduce opiate use on step down to High Dependency Unit (HDU) 4. Improve ICU Medical and Nursing staff perceived confidence in the management of oesophagectomy patients. Method(s): A multi-disciplinary approach was taken, with input from ICU, Surgical, Anaesthetic, Physiotherapy, Nursing, Pain and HDU teams. Standards of care for post-operative oesophagectomy patients were identified and a protocol was subsequently produced for use within ICU with reference to current Enhanced Recovery After Surgery (ERAS) guidelines.1 The protocol covered the first 5 days of post-operative care. It identified tasks to be completed each day and highlighted which staff group was responsible for performing each task. Additionally, an information sheet was distributed to Medical and Nursing ICU staff to educate them on oesophagectomy patients and recognition of potential complications that arise when caring for this patient group. Data on 30 day mortality and opiate use at step down to HDU was collected from electronic notes. This was collected retrospectively prior to implementation of the protocol from January 2019 - July 2020 and prospectively following its implementation, from October 2020 - December 2021. ICU staff perceived confidence in managing post-operative oesophagectomy patients was measured using a combined quiz and survey. It was completed by staff prior to introduction of the protocol. Following implementation of the protocol and distribution of the information sheet, the quiz and survey was repeated to evaluate improvement in staff confidence. Result(s): A total of 38 oesophagectomy cases were identified. 21 cases were reviewed prior to implementation of the protocol, with 1 mortality at 30 days. 17 cases were reviewed following implementation of the protocol, with 0 mortalities at 30 days. Qualitative scoring showed a 20% increase in staff confidence to manage this patient group. Review of drug prescription charts revealed a reduction in dose of modified release opiates at step down to HDU. Conclusion(s): Oesophagectomy is major surgery and causes significant staff anxiety in low volume centres. This protocol has successfully standardised care for this patient group and allowed continuation of this essential service provision during the COVID-19 pandemic. This protocol improved 30 day mortality, reduced opiate use at step down to HDU and improved ICU staff perceived confidence in caring for post-operative oseophagectomy patients.

Developing and evaluating the Digitally Enhanced Liberation from VEntilation (DELVE) system: A study of feasibility and user acceptance

Introduction: In common with many aspects of critical illness recovery, there is no universally accepted formula for "weaning," the term used to describe the process of liberating patients from mechanical ventilation.1-3 Understanding a patient's progress during a prolonged wean can be difficult and requires integration of various datasets. Therefore, it is good practice to ensure that weaning prescriptions are clear, easy to follow and adhered to and that weaning-associated data and meta data are recorded accurately and are easy to interpret. The prototype Digitally Enhanced Liberation from VEntilation (DELVE) system has been designed to be used in combination with the Puritan Bennett(TM) 980 (PB980) ventilator (Covidien, USA). DELVE is an open-loop system which provides an interactive weaning chart, combining the weaning prescription entered by the clinical staff, with actual settings recorded from the ventilator in order to display compliance with the prescription (Figure 1). DELVE also collects measured data from the ventilator which could be used to display respiratory performance, both real-time and historical. Figure 1. DELVE set up with the PB980 ventilator (in the simulation suite). Objective(s): This feasibility study was designed to inform development of the first DELVE prototype and a future clinical trial to determine clinical effectiveness and usefulness. The study objectives were to determine whether DELVE could: 1. Present a digital weaning chart that staff could use effectively and would be superior to the current paper version. 2. Record and display the patients' ventilatory performance, both real time and historical, during liberation from mechanical ventilation. Method(s): This was a mixed-methods, prospective feasibility study of a complex intervention.4 Ventilated patients with a tracheostomy, commencing the weaning process, were recruited from an adult intensive care unit. DELVE was used alongside the current paper-based system for weaning planning and data collection. Patients remained in the study until they no longer required the support of the PB980 ventilator. Result(s): Twenty patients were enrolled for between 25 and 270 hours each. There were no safety incidents or data breaches. DELVE was successfully operated by staff, who were able to connect DELVE to the ventilator, prescribe weaning plans and analyse adherence. The digital weaning chart user interface was intuitive and easy to navigate. It was clearer, more complete and easier to interpret when compared to the paper weaning charts (Figure 2). DELVE reliably collected data every ten seconds and safely stored over six million items of measured data and 25000 events, such as alarm triggers and setting changes, in a form that could allow analysis and pictorial or graphical presentation. Conclusion(s): This study supported the feasibility of this and future versions of DELVE to present both a digital weaning chart and to facilitate visual and numerical data presentation. Future iterations of the system could include a user-friendly dashboard representing patient progress during the weaning process. Assimilation of large volumes of data could be used to enhance understanding and inform decision making around the prolonged wean.
