Postoperative infections in the upper respiratory tract
1Department of Otorhinolaryngology, Södersjukhuset, Karolinska Institute, Stockholm, Sweden.
Abstract:
Pathogenesis, prophylaxis and treatment of postoperative infections in the upper respiratory tract are discussed. Surgical procedures always hamper the normal mucosal defence system, which means that true pathogens and members of the normal flora can establish a heavy growth that will, inevitably, to some extent challenge the humoral and cellular defense of the mucosal and submucosal tissues. It is stressed that the activation of granulocytes and macrophages, which leads to the release of proteolytic proteases, can cause tissue destruction and thus also bacterial invasion. Prophylaxis should be based on good surgical technique, efficient drainage of the wound and prevention of accumulation of secretions. Antibiotic prophylaxis is recommended in risk situations, such as in extensive surgery and when the wound extends through the tissue from the skin to the mucosa. Postoperative infections have to be treated with surgical drainage and elimination of devitalized tissues in combination with antibiotic regimes based on results of bacteriological analysis.
Insights
Preventing and treating upper respiratory tract infections after surgery involves understanding how surgical procedures compromise mucosal defenses. Effective strategies combine surgical technique, wound care, and judicious antibiotic use for optimal patient outcomes.
Area of Science:
- Otolaryngology
- Infectious Disease
- Surgical Pathology
Background:
- Surgical procedures can impair the upper respiratory tract's natural mucosal defense system.
- This impairment allows pathogens and normal flora to proliferate, challenging local immune responses.
- Immune cell activation can lead to tissue destruction and facilitate bacterial invasion.
Purpose of the Study:
- To discuss the pathogenesis of postoperative upper respiratory tract infections.
- To outline prophylaxis strategies for preventing these infections.
- To detail treatment approaches for established infections.
Main Methods:
- Review of pathogenesis mechanisms, including immune cell activation and tissue damage.
- Analysis of prophylactic measures: surgical technique, wound drainage, and secretion management.
- Evaluation of antibiotic prophylaxis indications and treatment protocols based on bacteriology.
Main Results:
- Surgical trauma compromises mucosal defenses, increasing infection risk.
- Prophylaxis relies on meticulous surgical practice and preventing secretion buildup.
- Antibiotic prophylaxis is crucial in high-risk scenarios like extensive or trans-mucosal wounds.
Conclusions:
- Effective prevention hinges on optimizing surgical techniques and wound care.
- Antibiotic prophylaxis should be reserved for specific high-risk situations.
- Treatment requires surgical intervention (drainage, debridement) coupled with targeted antibiotics.
