Cardiopulmonary resuscitation (CPR) is a lifesaving technique that many are familiar with, yet it comes with significant challenges. Traditional CPR relies on manual chest compressions, which can be inconsistent and difficult to maintain over time, particularly in high-stress or complex medical situations. This inconsistency can drastically reduce the effectiveness of CPR, putting patients at greater … Read more
Introduction Mechanical ventilation is a cornerstone of modern critical care and anesthesiology, providing essential respiratory support to patients who are unable to maintain adequate ventilation and oxygenation. Two critical parameters in the management of ventilated patients are peak airway pressure (Ppeak) and plateau pressure (Pplat). Understanding these pressures is crucial for optimizing ventilatory support, diagnosing … Read more
Introduction As we celebrate Doctor’s Day, it is fitting to honour one of the most pivotal figures in the history of medicine and anesthesia: Dr Crawford Long. His groundbreaking use of ether anesthesia transformed surgery, significantly reducing patient suffering and laying the foundation for modern anesthesiology. Today, we remember and celebrate his contributions to our … Read more
Introduction Diabetes management hinges on monitoring glycemia, with glycated hemoglobin (HbA1c) being a crucial indicator. HbA1c reflects average blood glucose levels over the past two to three months and is widely used to diagnose diabetes and monitor treatment efficacy. The discovery of HbA1c in the late 1960s revolutionized diabetes care by providing a reliable marker … Read more
Introduction The brain is an organ of immense complexity, requiring a robust blood supply to function correctly. Cerebral circulation is essential for delivering oxygen and nutrients while removing metabolic waste. This article explores the anatomy of the brain’s arterial supply, touches on venous drainage, and discusses important clinical aspects, including intracranial aneurysms, cerebral vasospasm, and … Read more
Introduction: Anesthesia is a critical component of tracheal surgery, particularly during the “open airway” phase. Ensuring adequate ventilation while maintaining surgical access to the trachea is a complex challenge that requires careful planning and execution. Various ventilation strategies have been developed to manage this delicate balance, each with its unique advantages and disadvantages. Understanding these … Read more
Newton’s first law of motion, often referred to as the law of inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This fundamental principle is not just a cornerstone of physics but also plays a critical role in the field … Read more
Newton’s second law of motion, F=maF=ma, is a foundational principle in physics that has broad applications in anesthesia, particularly concerning patient care, equipment design, and safety protocols. Ventilation and Respiratory Care In mechanical ventilation, the application of Newton’s second law, ( F = ma ), is evident in the relationship between the force applied by … Read more
Newton’s third law of motion states that for every action, there is an equal and opposite reaction. In the field of anesthesia, this fundamental principle has profound implications for patient care, equipment design, and surgical outcomes. 1. Endotracheal Tube Cuff Inflation When an anesthesiologist inflates the cuff of an endotracheal tube to secure it in … Read more
Serum renin, an enzyme produced by the kidneys, plays a crucial role in regulating blood pressure and fluid-electrolyte balance in the body. Serum renin, an enzyme involved in the renin-angiotensin-aldosterone system (RAAS), plays a significant role in regulating blood pressure and fluid-electrolyte balance. In the perioperative period, monitoring serum renin levels can provide valuable information … Read more
