Insights

Preoperative screening for methicillin-resistant Staphylococcus aureus (MRSA) is not recommended for general thoracic surgery patients, as both MRSA carriage and surgical site infections (SSIs) were found to be low in this study.

Area of Science:

  • Infectious Diseases
  • Surgical Outcomes
  • Public Health

Background:

  • Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) is a known risk factor for surgical site infections (SSIs).
  • Limited data exists on MRSA carriage rates and their impact on SSIs specifically within general thoracic surgery patient populations.

Purpose of the Study:

  • To investigate the significance of preoperative screening for nasal MRSA carriage in patients undergoing general thoracic surgery.
  • To determine the prevalence of MRSA nasal carriage and the incidence of SSIs in this surgical cohort.

Main Methods:

  • Retrospective analysis of 238 patients undergoing thoracic surgery.
  • Review of MRSA nasal carriage screening results and subsequent SSI development.

Main Results:

  • MRSA nasal carriage was identified in 4.6% of patients (11/238); 9 received nasal mupirocin.
  • Overall SSI rate was 1.8% (4/238), with all cases being pneumonia.
  • No SSIs occurred in patients with positive MRSA screening results; no wound infections, empyema, or mediastinitis were reported.

Conclusions:

  • This study observed low rates of both MRSA nasal carriage and SSIs in general thoracic surgery patients.
  • While hospital surveillance for MRSA is crucial, routine preoperative screening for nasal MRSA carriage is not advised for this patient group.

Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

The Thoracic Cage: Sternum01:17

The Thoracic Cage: Sternum

The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid...

The Thoracic Cage: Ribs01:20

The Thoracic Cage: Ribs

Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Pressure Relationships in Thoracic Cavity01:24

Pressure Relationships in Thoracic Cavity

Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

Resistivity01:22

Resistivity

When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:
