Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Assessment of Respiration01:23

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Respiratory Assessment: Purpose and Indications01:19

Respiratory Assessment: Purpose and Indications

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
Asepsis01:28

Asepsis

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.
Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Summary

Septic surgeries increase airborne microbes and particulate matter in operating rooms, posing risks for infection and occupational exposure. Environmental factors like temperature and door openings significantly impact microbial load.

Area of Science:

  • Environmental microbiology
  • Infection control
  • Occupational health

Background:

  • Surgical site infections (SSIs) are a significant public health issue.
  • Current prevention focuses on antibiotics and antisepsis, neglecting airborne contamination.
  • Operating room airborne contamination in septic procedures is understudied.

Purpose of the Study:

  • To assess environmental and microbiological changes during septic surgeries.
  • To understand implications for infection control.
  • To evaluate occupational exposure risks.

Main Methods:

  • Evaluated 20 septic surgical procedures.
  • Measured air quality, bacterial, and fungal loads.
  • Used MALDI-TOF for bacterial identification and Vester matrix for risk analysis.

Main Results:

  • Increased temperature, PM0.5, and Gram-positive bacteria intraoperatively.
  • Elevated fungal diversity persisted postoperatively.
  • Identified *Staphylococcus aureus* and *Pseudomonas aeruginosa*; seven risk scenarios highlighted factors like door openings and temperature.

Conclusions:

  • Septic surgeries alter operating room environments, increasing microbial burden.
  • Conditions promote microbial exposure, impacting infection prevention.
  • Findings are relevant for both patient safety and healthcare worker health.
