Design of Cecal Ligation and Puncture and Intranasal Infection Dual Model of Sepsis-Induced Immunosuppression
Published on: June 15, 2019
Summary
Improved management significantly reduced mortality rates for Gram-negative sepsis, particularly urologic sepsis. Early diagnosis, parenteral antibiotics, fluid balance, and glucocorticoid use were key factors in this improved patient outcome.
Area of Science:
- Medicine
- Infectious Diseases
- Critical Care
Background:
- Gram-negative bacterial infections pose a significant threat, with sepsis and septic shock leading to high mortality rates.
- Urologic sepsis represents a substantial subset of Gram-negative sepsis cases.
- Historical mortality rates for Gram-negative sepsis have varied, necessitating improved treatment strategies.
Purpose of the Study:
- To evaluate the impact of improved management procedures on mortality rates for Gram-negative sepsis, with a specific focus on urologic sepsis.
- To identify key components of effective sepsis management.
Main Methods:
- Retrospective analysis of 1236 Gram-negative sepsis cases from 1968-1973 at Columbia-Presbyterian Medical Center.
- Comparison of mortality rates with historical data from 1959-1967.
- Detailed examination of management protocols implemented during the study period, including preventive measures, diagnostic and treatment strategies, fluid management, and pharmacologic interventions.
Main Results:
- Overall mortality for Gram-negative sepsis decreased to 16.6% (205 deaths/1236 cases) during 1968-1973.
- Mortality for urologic sepsis specifically was 15.3% (19 deaths/124 cases).
- These rates represent a significant reduction compared to previous periods (56.3% in 1959-1964 and 19.6% in 1965-1967).
Conclusions:
- Improved management protocols, including preventive strategies, early diagnosis and treatment, fluid/electrolyte balance restoration, and judicious use of glucocorticoids and inotropes, are associated with significantly lower mortality rates in Gram-negative sepsis.
- Aggressive and comprehensive management is crucial for improving outcomes in patients with sepsis, especially urologic sepsis.

01:26Urinary Tract Infection I: Introduction
Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
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...
01:26Urine Studies II: Urine Culture and Sensitivity Test
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...
