Abstract

Insights

Pacemaker pocket infections (PPIs) are often caused by Gram-positive bacteria like Staphylococcus. Developing hospital-specific antibiotic policies is crucial to combat multidrug-resistant organisms and prevent PPIs.

Area of Science:

  • Infectious Diseases
  • Medical Microbiology
  • Cardiology

Background:

  • Pacemaker pocket infections (PPIs) are rare but can be caused by multidrug-resistant bacteria due to antibiotic misuse.
  • Limited data exists on the specific microbial spectrum of PPIs in the region.

Purpose of the Study:

  • To investigate the microbial spectrum of pacemaker pocket infections (PPIs).
  • To identify common pathogens and their antibiotic resistance patterns.

Main Methods:

  • Retrospective observational study conducted over 3 years (January 2013-February 2016).
  • Collected clinical samples (blood, pus) from 160 patients with PPI.
  • Included 100 environmental and staff samples as controls.
  • Microbial cultures and statistical analysis (P<0.05) were performed.

Main Results:

  • 10.6% (17/160) of patients developed PPI.
  • Coagulase-negative Staphylococcus (41.2%) and Staphylococcus aureus (23.5%) were the most common pathogens.
  • Multidrug-resistant bacteria, including Burkholderia cepacia and Mycobacterium abscessus, were identified.

Conclusions:

  • Gram-positive cocci are a significant cause of PPI.
  • Hospitals should tailor antibiotic policies based on local microbial flora and drug sensitivity patterns to manage PPI effectively.

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Pericarditis IV: Nursing Management

Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
