CHAPTER 11. SURGICAL INFECTION (PURULENT-INFLAMMATORY DISEASES)

54 topics with brief summaries: definitions, key facts, and classroom questions.

This chapter is dedicated to surgical infection, the cornerstone of general surgery. Here we examine the pathogens, pathogenesis, and endogenous intoxication syndrome, without which competent management of purulent-inflammatory diseases is impossible.

The section covers the entire spectrum of pathologies: from superficial skin and tissue processes (furuncle, carbuncle, erysipelas, necrotizing fasciitis) to deep and life-threatening conditions. You will study purulent diseases of the hand (felon), osteomyelitis, bursitis, as well as serous cavity infections—peritonitis, purulent pleurisy, and pericarditis. Special attention is paid to generalized forms, primarily surgical sepsis and its specific types.

At clinical sites and in examinations, differential diagnosis, surgical tactics (for example, the rules for opening deep limb phlegmons or felons), and principles of complex therapy are scrutinized most strictly. Pay special attention to the phases of inflammation—the choice between the scalpel and conservative management depends entirely on them.

Frequently asked questions for this section

What flora causes purulent surgical infection?

The disease is caused by pyogenic microbial flora. This is a nonspecific infection; its pathogens are neither viruses, nor fungi, nor specific anaerobic clostridia.

Which microorganism most frequently causes nosocomial infections in burn centers?

Pseudomonas aeruginosa, as it easily affects a weakened organism and suppresses the regeneration of damaged tissues.

Does the size of the wound affect the likelihood of developing a surgical infection?

No, the size of the injury is not decisive. The penetration of pyogenic microbes is equally possible in both extensive injuries and minor microtraumas.

What role does the gastrointestinal tract play in the development of toxemia?

In peritonitis and intestinal paresis, the gastrointestinal tract becomes the third source of intoxication. Digestive juices, bile, and enzymes stagnate, decompose, and are massively absorbed into the blood, increasing toxemia.

Can an abscess be cured with antibiotics alone?

No. Antibiotics complement but do not replace surgery. Delaying surgical intervention leads to severe complications.

What is the main difference between folliculitis and anthrax carbuncle?

Unlike folliculitis, the anthrax carbuncle is completely painless, has no purulent discharge, and is covered with a black escar with hemorrhagic vesicles at the periphery.
