Although alternative dosing strategies can improve antimicrobial exposure in critically ill patients, the high PK variability in this population means that some may still receive sub-optimal antibiotic exposure leading to unfavourable clinical outcomes. Therapeutic drug management (TDM) guided dosing is the only safe and effective way to ensure that all critically ill patients achieve therapeutic antimicrobial exposures and to minimise the likelihood of toxicity. For experts, TDM should be a standard of care, in particular for β-lactams. Nevertheless, because of the assay method for β-lactams and the need for bioanalytical experts, delays in obtaining results frequently occurred. These barriers, combined with difficulties in the interpretation of TDM results, need to be addressed in order to increase its routine utilization. Consequently, study aiming at identify which subgroup of patients or infection are more likely to benefit from TDM are urgently warranted This prospective observational study aimed at evaluating target attainment of piperacillin/tazobactam (PIP/TAZ) and cefepim (CEF) with the use of a Therapeutic Drug Monitoring (TDM) in critically patients during the routine care
this study is conducted to evaluate the role of the novel triple therapy combination in reducing the mortality rate, reducing the shock time, and reversal of organ damage. the study includes two arms, the first arm is the control which received hydrocortisone monotherapy and the second arm is the intervention arm which received the triple therapy regimen. calculation of 28 days in-hospital mortality is the primary outcome. shock time, vasopressor doses, infection markers, and organ function tests are the secondary outcomes. the data will be analyzed by student t-test or Mann Whitney test, Fischer exact or chi-square test for numbers, repeated measures ANOVA will be used to consider confounders and other parameters, mortality will be expressed by Kaplan Meier and ROC curve. For Multivariate analysis of repeated quantitative outcomes, linear mixed models were used to quantify the relationship between one dependent variable (SOFA, SCr, doses of vasopressors) and many independent variables including group type and sepsis phenotype adjusted to other clinical and demographic factors.
The purpose of this study is to determine the most suitable dose of Fludrocortisone in reversal of sepsis and shock associated with sepsis in patients who are admitted to the ICU. The investigators will be looking to see whether patients receiving Fludrocortisone at different doses recover quicker and spend less time in hospital and in ICU, and to understand the reasons why this happens at certain doses. Sepsis is caused by toxic substances (toxins) from bacteria and other organism entering the bloodstream from a site of infection. In some people, the infection can progress to sepsis and septic shock where the functions of organs in the body are affected. Patients suffering from sepsis and septic shock are commonly managed in the intensive care unit (ICU) where they are prescribed antibiotics as standard therapy, as well as other therapies to support the functions of the body. Fludrocortisone is a steroid that has previously shown to be beneficial to help in shock in patients in ICU, but more information is required about the exact dose that is required to achieve this. This has been shown by previous research. However, the exact role of Fludrocortisone and the best dose has not been studied adequately to date as well as the ways in how it works within the body. The study aims to look tat the dose and the way it works.
During Infection, oflfending microbes interact with the host immune system producing a downstream inflammatory cascade involving cytokines and other mediators, which in turn triggers a systemic response. The resultant effects linclude vasodilation, increased vascular permeability, myocardial depression, and impairment of the coagulation cascade, resulting in global imbalance of systemic oxygen supply and demand. During the late stage of sepsis, immunosuppression predominates, leading to multi-organ dysfunction and further clinical deterioration . Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection with two or three on Quick Sepsis-related organ failure assessment score (qSOFA). Septic shock is defined as the presence of sepsis and refractory hypotension to fluid management. Vasopressors are needed to maintain systolic blood pressure more than 90mmHg or mean blood pressure more than 65 mmHg . Experimental and Clinical evidence suggests that sepsis is associated with dysregulated response of Hypothalamic-pituitary-adrenal axis that may involve any of the steps from cortisol production to cortisol use by cells . Glucocorticoid therapy for the treatment of septic shock remains controversial, with conflicting evidence regarding a mortality benefit. It has been used in patients with septic shock who remained hypotensive after fluid and vasopressor resuscitation. Fludrocortisone is a corticosteroid and acts as a powerful mineralocorticoid along with some additional but comparatively very weak glucocorticoid activity. Relative to cortisol, it is to 10 times the glucocorticoid potency but 250 to 800 times the mineralocorticoid potency . Fludrocortisone is added to hydrocortisone to provide additional mineralocorticoid potency. The rationale for adding mineralocorticoid treatment is that an experimental sepsis study showed marked nuclear factor NF-κB mediated down regulation of vascular mineralocorticoid receptors . Corticosteroids attenuate inflammation in various organs an effect partly related to inhibition of nuclear factor NF-κB. Improve cardiovascular function by restoring effective blood volume through increased mineralocorticoid activity and by increasing systemic vascular resistance through vascular α-Adrenergic responsiveness and reduces inflammation-mediated vasodilation .
Fluid responsiveness prediction prior to fluid challenge administration is a topic of interest, which has been extensively investigated, but remains challenging. In clinical practice, functional hemodynamic tests (FHT) consisting of maneuvers that affect cardiac function and/or heart-lung interaction, have been introduced in order to identify fluid responders and non-responders without fluid challenge administration. Changes in cardiac output induced by the Passive Leg Raising (PLR) test reliably predicted the increase in cardiac output to volume expansion. New approaches have been recently developed based on changes in respiratory dynamics, such as a transient increase in tidal volume, or a lung recruitment maneuver or an end-expiratory occlusion (EEO) test. The EEO leaded to an increase in venous return, cardiac preload and stroke volume in preload-responsive patients. The authors found that an increase in cardiac output ≥ 5% during a 15-s EEO reliably predicted its response to a 500-ml saline infusion. However, in order to identify the rapid and transient increase in cardiac index during the EEO, continuous and instantaneous cardiac output monitoring is necessary. Pulse contour analysis methods provide a beat-to-beat estimation of cardiac output and had been used in most of studies validating the EEO test. Carotid doppler is a non-invasive, bedside, easy to use ultrasound technique that measuring blood flow peak velocity (CDPV) and duration of systolic component of each cardiac cycle (from the onset to dicrotic notch- Flow time - FT) allows a reliable estimation of fluid status and could be an interesting alternative to track changes in SV and cardiac output.
The sepsis and septic shock remain major causes of child morbidity and mortality, despite the use of modern antibiotics and resuscitation therapies. Recent interest has focused on biomarkers for early diagnosis, and evaluation the outcomes of sepsis; but there is a still lack of early diagnosis and timely intervention for sepsis in the emergency department (ED). The primary aim was to investigate the role of C-Reactive Protein(CRP), Procalcitonin(PCT), soluble-urokinase plasminogen activator receptor(suPAR) and Presepsin in the early stratification of patients with sepsis. The usefulness of pediatric Sequential Organ Failure Assessment (pSOFA) for predicting of the mortality and the rate of PICU admission in children with septik shock were also investigated. This prospective pilot study was conducted at academic pediatric ED between September 2017-June 2018. All children who met sepsis criteria admitted to ED were involved to study. They kept following up after ED management and their blood samples were taken upon admission on day 0, 1, 2, 4 and 7. The definition made as sepsis, severe sepsis and septic shock. At the same period, 100 healthy children chosen as the control group. The patient characteristics, clinical features, diagnosis, co-morbidities, source of infection, laboratory results (CRP, PCT, lactate, suPAR and Presepsin) and treatments were recorded. The pSOFA score was calculated during first hour of admission. Length of stay in ED and hospital was noted. The main outcome measure was in 7 and 30-day mortality.
Evaluation of preload responsiveness in ARDS patients during prone position is difficult and only one study showed Trendelenburg manoeuvre can be used in this group of patients. This study aims to investigate whether end-expiratory occlusion test, tidal volume challenge (using the changes in PPV) can be used to evaluate preload responsiveness in patients with ARDS ventilated with a low tidal volume and who underwent a PP session.
Coronavirus disease 2019 (abbreviated "COVID- 19") is a pandemic respiratory disease that is caused by a novel coronavirus and was first detected in December 2019 in Wuhan, China. The disease is highly infectious, and its main clinical symptoms include fever, dry cough, fatigue, myalgia, and dyspnoea.1 In China, 18.5% of the patients with COVID-19 developed to the severe stage, which is characterized by acute respiratory distress syndrome, septic shock, difficult-to-tackle metabolic acidosis, and bleeding and coagulation dysfunction. After China, COVID-19 spread across the world and many governments implemented unprecedented measures like suspension of public transportation, the closing of public spaces, close management of communities, and isolation and care for infected people and suspected cases. The Malaysian government had enforced Movement Control Order (MCO) from 18th March to 4th May 2020 and henceforth Conditional Movement Control Order (CMCO) until 9th June 2020. The battle against COVID-19 is still continuing in Malaysia and all over the world. Due to the CMO and CMCO in the country, public and private universities have activated the e-learning mode for classes and as the government ordered, universities are closed and no face-to-face activities allowed. This has forced students of all disciplines including dentistry to stay at home which are wide-spread across Malaysia and shift to e- learning mode. To guarantee the final success for fight against COVID-19, regardless of their education status, students' adherence to these control measures are essential, which is largely affected by their knowledge, attitudes, and practices (KAP) towards COVID-19 in accordance with KAP theory. Once the restrictions are eased students have to come back and resume their clinical work in the campus. Hence, in this study we assessed the Knowledge, Attitude, and Practice (KAP) towards COVID-19 and the students preference for online learning.
Septic shock is a subset of sepsis characterized by a decrease in vascular tone, which contributes to impaired regional blood flow distribution, and leads to organic failure. Besides intravenous fluids and adequate antimicrobial therapy, patients with septic shock require vasopressor support, which can lead to many adverse effects, therefore, non-vasopressor agents that can improve hemodynamic status are needed. In this randomized controlled-study, the investigators will address the efficacy and safety of infusion with methylene blue in patients with septic shock.
