Filter by:Nepal and the South Asian sub-continent carry some of the highest rates of burn injury globally, with an associated high morbidity and mortality. Nepal currently has one major center equipped for burn care, in Kirtipur, Nepal and receives referred patients from around the country. At presentation, most patients with major burns have had minimal to no resuscitation on arrival, often hours to days after the burn injury was sustained. Timely fluid resuscitation, initiated as soon as possible after major burn injury, is the main tenet of acute burn care. Lack of adequate resuscitation in major burn injuries leads to kidney injury, progression of burn injury, sepsis, burn shock, and death. The current standard of care for major burn resuscitation is intravenous fluid resuscitation. In Nepal, however, adequately trained and equipped hospitals for treatment of burn care are not available (for a variety of reasons). Additionally, there is not a systematic emergency medical transport system available for provision of medical care and resuscitation during transport. Enteral-based resuscitation with substances like the WHO Oral Rehydration Solution (ORS) is recommended by burn experts and the professional burn societies when resources and access to intravenous fluid resuscitation are not available in resource-constrained settings such as rural areas, low- and middle-income countries, and military battlefield scenarios. Studies have previously demonstrated the efficacy and safety of enteral-based resuscitation in controlled, high-resource settings, however there have not been real-world effectiveness trials in austere settings. Therefore, the investigators seek to ultimately address the problem of pre-hospital and pre-burn center admission resuscitation by studying the feasibility and effectiveness of enteral resuscitation with Oral Rehydration Solution (ORS) in preventing burn shock. This study examines enteral (oral)-based resuscitation with ORS and IV Fluids versus only IV Fluids for the treatment of major burn injuries. The intervention portion of the study will entail randomization of patients presenting with acute burn injuries of 20-40% total body surface area (TBSA) to an enteral-based resuscitation versus the standard of care IV fluid resuscitation. The intervention will continue through the 24-72 hours of the acute resuscitation period. This is a feasibility study, primarily to develop and establish the research infrastructure and practices at the study site for future pilot study and eventually randomized-controlled trial research on this intervention. The primary outcomes will be measures of feasibility such as the adherence rate to the resuscitation protocols. Further, there will be a qualitative component to the study with focus group interviews of the bedside healthcare providers (doctors and nurses) who are caring for the enrolled patients, in order to understand the challenges and facilitators of enteral resuscitation. Qualitative analysis will be done to understand the major themes of challenges and facilitators to enteral resuscitation.
In the last decade, venoarterial extracorporeal membrane oxygenation (VA-ECMO) has become the first-line therapy in patients with refractory cardiogenic shock. VA-ECMO provides both respiratory and cardiac support, is easy to insert, even at the bedside, provides stable flow rates, and is associated with less organ failure after implantation compared to large biventricular assist-devices that require open-heart surgery. In patients with potentially reversible cardiac failure (e.g. myocarditis, myocardial stunning post-myocardial infarction, post-cardiotomy or post-cardiac arrest), VA-ECMO might be weaned after a few days of support and used as a bridge to recovery. Although considered as the ultimate life-saving technology for refractory cardiac failure, veno-arterial ECMO is still associated with severe complications. Specifically, excessive LV afterload and lack of LV unloading under VA-ECMO might induce LV stasis with thrombus formation, pulmonary edema, myocardial ischemia caused by ventricular distension and ultimately increase mortality. ECMO support also exposes to many complications such as infections, hemorrhage or peripheral vascular embolism. These complications are more frequent with prolonged support and are responsible for significant morbidity and mortality, prolonged ICU and hospital stays and higher costs. Levosimendan, which acts to sensitize myocardial contractile proteins to calcium, improves cardiac contractility without increasing the intracellular calcium concentration. Unlike traditional inotropes such as dobutamine, levosimendan neither increases myocardial oxygen consumption nor impairs diastolic function or possess proarrhythmic effects. It also influences the opening of ATP-dependent potassium channels, including those in vascular smooth muscle cells, leading to coronary, pulmonary, and peripheral vasodilation and antiinflammatory, antioxidative, antiapoptotic, anti-stunning and cardioprotective effects. Additionally, Levosimendan which has a long lasting action (up to 7-9 d), resulting from the formation of active metabolite, may be used as a single 24h perfusion. In recent preliminary studies, the drug was associated with accelerated weaning from VA-ECMO and even improved survival. Therefore, a multicenter randomized trial with sufficient statistical power is needed in refractory cardiogenic shock patients supported by VA-ECMO to test if the early administration of Levosimendan can facilitate and accelerate VA-ECMO weaning, and ultimately translate in significantly less morbidity, reduced ICU and hospital length of stays and associated costs.
This clinical study aims to compare the recent septic shock management protocol from American College of Critical Care Medicine (ACCM) to Ultrasound-guided Septic Shock Management (USSM) protocol. USSM protocol laid on Doppler ultrasonography to evaluate stroke volume, cardiac index, and systemic vascular resistance in each step of management to decide the proper fluid resuscitation and vasoactive therapy; differs from ACCM protocol which use clinical finding in its early step. ACCM protocol application elicits risk of improper therapy since clinical sign per se often could not describe the certain cardiac output. This can be prevented earlier by USSM protocol. The outcome compared of the two protocols is: mortality rate, clinical parameter, macrocirculation hemodynamic parameter, laboratory microcirculation parameter, and signs of fluid overload. The investigators hypothesized if the USSM protocol had a better outcome and less fluid overload complication.
Evaluation of plasma angiotensin II and angiotensin II receptor levels in patients with sepsis and septic shock: a prospective observational study.
End-stage renal disease (ESRD) is an important risk factor for coronary and valvular cardiac disease leading to cardiac surgery. with concern for higher post-op complications with volume overload and coagulopathies in this patient' outcomes as mentioned above in patients who receive early post-op dialysis versus hemodialysis on day 1 or thereafter. ed for mechanical ventilation and rs of clinical course and mortality. Previous studies have demonstrated that presence of ESRD is an independent risk factor for post-operative respiratory failure and mortality in patients undergoing cardiac surgery, partially mediated through volume overload and prolonged mechanical ventilation, as well as coagulopathy attributed to platelet dysfunction and uremia. Prolonged mechanical ventilation after cardiac surgery has been shown to be associated with higher morbidity and mortality. Fluid overload is a predictor of length of mechanical ventilation and intensive care unit (ICU) stay. Therefore early restoration of volume and electrolyte homeostasis and clearance of uremic toxins should be one of the principal goals in the immediate post operative period in patients with ESRD. However, to the best of our knowledge, the effect of timing of post-operative renal replacement therapy, specifically hemodialysis, on clinical outcomes has not been studied in ESRD patients undergoing cardiac surgery. Accordingly, we have conducted this study to evaluate the effect of early population affecting their overall hospital course including longer duration of ICU stay, need for mechanical ventilation support and blood products transfusion we are planning to conduct this study and compare the short term hemodialysis treatment after cardiac surgery, on clinical outcomes related to volume overload and coagulopathy (i.e. duration of mechanical ventilation, transfusion requirements, and length of ICU stay) in patients with ESRD
Transthoracic echocardiography (TTE) has been used as a reference technique for CO measurement and its accuracy has been adequate for many clinical uses. TTE is painless, safe and non-invasive. Some drawbacks of TTE are being expensive, bulky and needs advanced training. Currently, due to increased interest in minimally invasive hemodynamic monitoring, multiple new methods have become commercially available to assess CO: the arterial pulse aortic flow, bioreactance, and bioimpedance. One of these new devices is LiDCOrapid (LiDCO Ltd, Cambridge, UK). It is a new, minimally invasive monitor which estimates beat-by-beat CO and fluid responsiveness from the arterial waveform. It has been validated after vascular, urological and thoracic surgery and shows good agreement with the PA catheter in swine, in patients with normal left ventricular systolic function and in patients with vasodilatation. However, LiDCO has not yet been validated in patients with septic shock. Therefore, the aim of this study is to validate LiDCOrapid parameters in septic shock patients using TTE derived parameters as the non-invasive reference.
In septic shock patients, the hemodynamic coherence between systemic, regional and microcirculatory blood flow can be tracked by "capillary refill time (CRT) response to an increase in stroke volume induced by a rapid fluid challenge". A parallel improvement in regional blood flow, microcirculation and hypoperfusion-related parameters should be expected in CRT-responders as reflection of preserved hemodynamic coherence. CRT non-response is associated with a more severe systemic inflammatory state, endothelial and microvascular dysfunction, and a higher adrenergic tone. The objective of this study is to determine if CRT response after a rapid fluid challenge signals a state of hemodynamic coherence as demonstrated by a parallel improvement in regional and microcirculatory blood flow in CRT-responders, and to explore the pathophysiological mechanisms associated to CRT non-response.
The Cardiogenic Shock Working Group is a multicenter registry where we collect de-identified clinical variables from the medical records and follow-up phone calls of shock patients from multiple institutions and centralize this data to a single registry for analysis of clinical outcomes.
Precision/personalized medicine becomes an important part of modern medical system in the recent years. In the past, the treatments for patients have been decided by doctors according patients' symptoms and/or regular biochemical profiles. However, it is not uncommon that patients' condition varies tremendously even they have same diagnosis, and under such condition, treatment efficacy may be limited due to the heterogeneity among patients. Therefore, lack of therapeutic efficacy may be not really ineffective, and the main reason may be inadequate patient classification. For this reason, the "omics"-based personal/precision medicine emerges recently and becomes more and more important. However, in contrast to feasible and common "personalized" medicine, the approach of precision medicine to the molecular medicine level is still difficult, especially among patients in intensive critical units (ICUs). In contrast to cancer, which has remarkable advances in the past decades, the precision/personal medicine is more difficult in critical and emergent medicine. One reason is the amount of omics data is quite huge and thus dealing with omics data is time consuming. Therefore, it is not effective in daily clinical practice in ICUs care. For this condition, the investigators propose that the combination of clinical data, including pulse diagnosis by traditional Chinese medicine (TCM) doctor or ANSwatch wrist sphygmomanometer, fluid responsiveness by "Masimo" Radical-7 Pulse CO-Oximeter, and the specific database from monitors in ICUs may be a feasible way to predict outcome among ICU patients. There are two main goals for this study: (1) After establishing clinical traditional Chinese medicine (TCM) pulse diagnosis and ICU clinical parameters databases, acquiring and features of pulse diagnosis by applying AI and (2) analyzing the correlations between the features of pulse diagnosis and important clinical parameters.
