Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care01:29

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

532
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

6.0K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Asepsis01:28

Asepsis

3.5K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Urine Studies II: Urine Culture and Sensitivity Test

1.5K
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

Acute Pyelonephritis II: Diagnostic Studies and Management

490
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Area of Science:

  • Critical Care Medicine
  • Infectious Diseases
  • Pathophysiology

Background:

  • Sepsis incidence is increasing globally, driven by factors like an aging population, immunosuppression, and antibiotic resistance.
  • Despite rising incidence, sepsis survival rates have improved due to advances in intensive care and adherence to evidence-based guidelines.
  • Sepsis is defined as life-threatening organ dysfunction arising from a dysregulated host response to infection, with severity assessed by the Sequential Organ Failure Assessment (SOFA) score.

Purpose of the Study:

  • To discuss the latest definitions of sepsis and the scientific community's response.
  • To provide an overview of current understanding regarding sepsis pathogenesis.
  • To present updated treatment guidelines for sepsis management.

Main Methods:

  • Literature review and synthesis of current research on sepsis definitions, pathogenesis, and treatment.
  • Analysis of the impact of new definitions and guidelines on clinical practice.
  • Discussion of emerging research trends and future directions in sepsis care.

Main Results:

  • The article details the new definitions of sepsis and explores the ongoing discourse surrounding them.
  • It provides insights into the complex mechanisms underlying sepsis pathogenesis.
  • Updated treatment guidelines incorporating recent advancements are presented.
