65 Trial

Dr Swapnil Pawar March 15, 2020

Effect of Reduced Exposure to Vasopressors on 90-Day Mortality in Older Critically Ill Patients With Vasodilatory HypotensionA Randomized Clinical Trial François Lamontagne, MD1,2; Alvin Richards-Belle, BSc3; Karen Thomas, MSc3; et al Introduction- Vasopressors are commonly administered to patients in intensive care units (ICUs) to treat in order to prevent hypotension associated myocardial injury, kidney injury, and death. Vasopressors, however, may reduce blood flow in vasoconstricted vascular beds and are associated with effects on cardiac, metabolic, microbiome, and immune function. Balancing risks of hypotension with risks from vasopressors is, therefore, a challenge when managing patients in ICUs. Blood pressure is used to guide the administration of vasopressors. The norm is […]

Hyperoxemia in Intensive Care

Dr Swapnil Pawar March 5, 2020

Oxygen is a vital element and impaired oxygen delivery in critically ill patients is associated with increased mortality.  As a consequence, reassuring oxygen delivery has become a cornerstone of many resuscitation protocols and liberal use of supplemental oxygen is common.  This is predominantly due to our understanding of physiology. Oxygen is a critical element to fuel oxidative phosphorylation for the generation of ATP by mitochondria. Since ATP is mainly produced by means of oxidative phosphorylation, hypoxemia may impair the production of ATP and thereby lead to cellular ATP depletion. On the contrary, The negative effects of too much oxygen are less clear and many health care professionals […]

NONSEDA Trial

Dr Swapnil Pawar February 28, 2020

Nonsedation or Light Sedation in Critically Ill, Mechanically Ventilated Patients Invasive mechanical ventilation after tracheal intubation is among the most frequently performed procedures in adult patients admitted to the intensive care unit (ICU). Sedation and analgesia are provided at the time of intubation and may be maintained for hours or days. The aim of sedation is to minimize oxygen consumption and facilitate a patient’s ability to remain comfortably connected to a ventilator. Over the past two decades, it has been recognized that prolonged and deep sedation can increase the duration of mechanical ventilation, delay weaning, impair neuromuscular function, produce delirium, […]

De-resuscitation in Intensive Care

Dr Swapnil Pawar February 20, 2020

The accumulation of a positive fluid balance is a frequent occurrence in critically ill patients. As Paracelsus said, ” All things are poisons, nothing is without poison. Only the dose permits something not to be poisonous.” Like other drugs, it is the dose of fluids which makes them poisonous. What is de-resuscitation? Where did this term originate from?The use of intravenous fluid therapy is universal among critically ill patients to optimize tissue perfusion and oxygen delivery. Apart from intravenous fluids administered during initial resuscitation, fluid accumulation occurs from nutrition, maintenance fluids, and diluents used for intravenous drug therapy. An aggressive […]

Sir William Osler said that “except on a few occasions, the patient appears to die from the body’s response to infection rather than from the infection” Sepsis is a major problem across the globe. Apart from the enormous financial costs of sepsis, the human toll of this disease is staggering and new interventions that limit the ravages of this disease are urgently required. Despite numerous RCTs, we still have not found the magic bullet to cure sepsis. The role of Vitamin C in Sepsis has been debated a lot recently.

Permissive Hypercapnia in ARDS

Dr Swapnil Pawar February 3, 2020

Lung protective ventilation has become the cornerstone of the management of ARDS patient. As a consequence, hypercapnia is inevitable. However, permissive hypercapnia is not without its own problems. In this podcast, we discuss this dogma and challenge traditional practices.  What is permissive hypercapnia? Permissive hypercapnia is a ventilation strategy that allows an unphysiologically high partial pressure of carbon dioxide (PCO2) to permit lung protective ventilation with low tidal volumes. The term “permissive hypercapnia” was coined by Hickling and associates in the early 1990s in their seminal descriptions of improved survival in ARDS in which plateau pressures and tidal volumes were limited.

Driving Pressure Vs Tidal Volume in ARDS

Dr Swapnil Pawar January 20, 2020

Recently there has been a growing interest in driving pressure as a significant parameter for titration in mechanical ventilation for ARDS patients. It has challenged our dogma of 6-8 mls/kg tidal volume ventilation. In this podcast, we discuss the current evidence and future of mechanical ventilation in ARDS.  Our understanding of mechanical ventilation in ARDS has evolved significantly since the year 2000. The key concepts that have been accepted in practice include low tidal volumes, low plateau pressure, lower driving pressures and reduced frequency of injurious strain cycles. The main focus is to avoid ventilator-associated lung injury. With the recent […]

Effect of early nutritional support on Frailty, Functional Outcomes, and Recovery of malnourished medical inpatients Trial (EFFORT) trial Anorexia arises as a physiological response to acute illness and predisposes hospital inpatients to serious caloric and protein deficits. In combination with immobilisation and pronounced inflammatory and endocrine stress response, these nutritional deficits contribute to muscle wasting and progressive deterioration of metabolic and functional status, particularly in medical patients with multiple morbidities. Hospitals don’t provide the best possible food and often patients complain about the quality of the food.  More than 30% of medical inpatients are at increased risk of malnutrition, a […]

Thrombolysis in Submassive PE

Dr Swapnil Pawar December 31, 2019

The role of thrombolysis in submassive PE remains controversial to date. In this podcast, Dr Chacko & I dive deeper to explore the current evidence on this topic. What is Submassive PE and what are the key differences between Submissive and Massive PE The terms massive, submassive, and low-risk PE have been coined to risk stratify PE based on the likelihood of mortality. Massive PE is characterized by sustained hypotension with a systolic pressure of < 90 mm for >15 minutes or the requirement for vasopressor support. A submassive PE does not cause hypotension but causes right heart strain, dilation, […]

ICP Monitoring in TBI

Dr Swapnil Pawar December 1, 2019

TBI remains a major cause of death and disability worldwide. Poor outcome is associated in part with the primary insult and importantly from secondary brain injury, which is a complex series of pathologic events triggered in the early phase after TBI that then evolve over time. Apart from treating Primary pathology, modern TBI management focuses on the prevention, identification and management of SBI.  Neuromonitoring is central to SBI management. This includes serial clinical examination, imaging and the use of invasive and non-invasive devices that allow cerebral physiology to be assessed over time. Traditionally neuromonitoring has focussed on ICP monitoring which […]

CVS Physiology Part 2

Dr Swapnil Pawar December 1, 2019

The cardiovascular events that occur during these phases can be subdivided into mechanical and electrochemical events: Ventricular Systole: Mechanical Isovolumetric contraction At the beginning of ventricular systole, the atrioventricular valves close, heard as the first heart sound, and the intraventricular pressure rises rapidly. This rise in pressure causes the AV valves to […]

Effects of tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic brain injury (CRASH-3): a randomised, placebo-controlled trial Intro –  As we know, TRANEXAMIC ACID is a synthetic analogue of the amino acid Lysine. It reduces bleeding by preventing the breakdown of fibrin clots i.e fibrinolysis. The CRASH-2 trial showed that in patients with trauma with major extracranial bleeding, early administration (within 3 h of injury) of tranexamic acid reduces bleeding deaths by a third. Subsequent analyses showed that even a short delay in treatment reduces the benefit of tranexamic acid administration. However, […]

Dr Swapnil Pawar & Dr Jose Chacko What is ARC? Augmented renal clearance (ARC) is the phenomenon of enhanced renal function in critically ill patients. ARC is characterized by a higher than predicted increase in the renal elimination of solutes. It occurs due to an increase in glomerular filtration and altered renal tubular function, usually manifest as an increase in the creatinine clearance. ARC leads to increased clearance of drugs excreted through the kidneys resulting in suboptimal concentrations of important medications, including antibiotics, and may lead to treatment failure. This phenomenon was first described more than 40 years ago in […]
