Abstract

Insights

Intrapleural antibiotic irrigation, commonly with vancomycin, is a well-tolerated treatment for postpneumonectomy empyema (PPE) after thoracic surgery. Recurrence of PPE was observed in 28% of patients within six months.

Area of Science:

  • Thoracic Surgery
  • Infectious Diseases
  • Pharmacology

Background:

  • Postpneumonectomy empyema (PPE) is a serious complication following lung cancer surgery.
  • Intrapleural (IP) antibiotic irrigation is considered when systemic therapy and drainage are insufficient.

Purpose of the Study:

  • To evaluate the use and outcomes of IP antibiotic irrigation for treating PPE.
  • To identify common antibiotic agents and treatment protocols.

Main Methods:

  • Retrospective analysis of 18 adult patients who received IP antibiotic irrigation between 2006-2011.
  • Data collected included demographics, surgical history, systemic antibiotics, and IP antibiotic details (agent, dose, preparation).

Main Results:

  • Most patients (72%) underwent extrapleural pneumonectomy (EPP).
  • Vancomycin was the predominant antibiotic for both systemic therapy (100%) and IP irrigation (94%).
  • The median number of IP doses was 5.5, with 28% experiencing PPE recurrence within 6 months. Treatment was well tolerated.

Conclusions:

  • Vancomycin is the most frequently used antibiotic for IP irrigation in PPE management at this institution.
  • IP antibiotic irrigation is a safe and potentially effective adjunct therapy for refractory PPE.

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pneumonia IV: Management

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
