Introduction:
The MRSA and MSSA infections are essential clinical problem. Both of the strains have high virulence (as a result of enzyme and toxin production), what disturbs wound healing as well as a general condition of the patient.
Aim:
The purpose of this work was an estimation of the role of MRSA infections among patients operated on for head and neck cancers.
Material And Methods:
From 1155 patients treated for head and neck cancers in The Department of Otolaryngology in Poznan in 2006-2007 189 biological samples were taken to carry out a bacteriological examination. The indications for this procedure were symptoms of infection in the operated area, wound healing per secundam and a hectic fever after the surgery. Biological specimens came from: 57 postoperative wounds, 36 tracheotomy areas, 24 tracheoesophageal fistulas, 9 salivary fistulas, 21 oral cavities and pharynxes, 2 noses, 4 ears, 6 central venous catheter areas, 2 gastrostomies, 2 cerebrospinal fluid (CSF) samples, 1 fluid from pleural cavity, 11 blood samples, 12 urine samples, 2 bronchoalveolar lavages (BAL).
Results:
37 biological samples were aseptic, in 11 samples there were no pathological cultures, in 141 samples pathological bacterial flora was found. MRSA was found in 6 cultures and MSSA was found in 18 cultures.
Conclusions:
In order to prevent the MRSA infection the Hospital Infections Department was formed. The results of commissioned bacteriological examinations are analyzed by the Department, what enables bacteriological flora observation in the hospital, fast identification of MRSA infected patients, and, what is more, MRSA infections prevention. It also helps to select proper medicaments in empiric antibiotic therapy.
Insights
Methicillin-resistant Staphylococcus aureus (MRSA) infections pose a significant clinical challenge, particularly in head and neck cancer patients. This study identified MRSA in 6 cultures, highlighting the need for vigilant monitoring and prevention strategies in surgical settings.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Oncology
Context:
- Head and neck cancers present complex treatment challenges, often involving surgery.
- Bacterial infections, including those caused by Staphylococcus aureus strains like MRSA and MSSA, can complicate patient recovery.
- These infections are associated with high virulence, impacting wound healing and overall patient health.
Purpose:
- To evaluate the prevalence and role of MRSA infections in patients undergoing surgery for head and neck cancers.
- To assess the bacteriological flora in various sample types from these patients.
Summary:
- A bacteriological examination was conducted on 189 biological samples from 1155 head and neck cancer patients treated between 2006-2007.
- Pathological bacterial flora was identified in 141 samples.
- MRSA was detected in 6 cultures, and Methicillin-sensitive Staphylococcus aureus (MSSA) was found in 18 cultures.
Impact:
- The findings underscore the importance of monitoring for MRSA in surgical patients.
- The establishment of a Hospital Infections Department aids in observing bacteriological flora, identifying infected patients, and implementing prevention strategies.
- This surveillance facilitates the selection of appropriate empirical antibiotic therapy, improving patient outcomes.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
