history
History
  • Lister: 1867 On the antiseptic principle in practice of surgery
  • Louis Pasteur, Ignaz Semmelweis, Theodor Kocher and William S. Halsted
  • Application of antiseptic practices allowed infection rate of operation to drop from 90% to 10%.
history3
History
  • Antibiotics: introduced in the middle of 20th century
  • Hope serious surgical infection eliminated, but this did not occur.
  • Nosocomial infection, widespread antibiotics therapy
  • New techniques: endoprosthesis, transplantation requires immunosuppressive agents, et al.
definition
Definition

The infection required operative intervention, including that complicated from trauma, operation and burns, et al.

Caused by the invasion, resident and proliferation of pathogens, such as bacteria, viruses and fungi et al.

classification
Classification:

Pathogenesis:

Non-specific infection: suppurative infection

presentation: redness, swelling, hot, soreness

pathogens: Staphylococci aureus, Streptococci.

Specific infection: tuberculosis, tetanus, gas gangrene, fungi

Etiology

Causes of surgical infection:

normal bacterial flora---pathogenic bacteria

exogenous bacteria

low host resistance

etiology10
Etiology

Bacteria factors:

adherence

toxins: exotoxin, endotoxin

numbers of bacteria: 105

etiology11
Etiology

Local factors:

injury of skin or mucosa

duct obstruction

blood supply

skin or mucosa diseases

etiology13
Etiology

Systemic factors:

  • severe disease
  • hormone
  • malnutrition
  • AIDS
pathology
Pathology
  • Non-specific infection:
  • bacteria proliferation
  • leucocyte infiltration
  • inflammatory media and cytokines release
  • congestion, excudation
  • accumulation of serum, blood cells, necrotic tissues
  • redness, swelling, hot and soreness, and dysfunction.

diagnosis
Diagnosis
  • Clinical presentation:

systemic condition

local condition

organic-systemic dysfunction

specific expression

  • Investigation:

experiment test

imaging: US, X-ray,CT, MRI

management
Management
  • Local treatment:
  • protect infection site
  • superficial lesion
  • deep lesion
  • Antibiotics:
management20
Management
  • Improve systemic conditions:

hydro-electrolyte,

nutrition

companion diseases

furuncle
Furuncle
  • Acute suppurative infection within one hair-follicle and surrounding tissue
  • Pathology: acute suppurative inflammation
  • congestion and exudation of components of blood

Furunculosis: infection of several hair follicles in a circumscribed area.

carbuncle
Carbuncle
  • A confluent infection involving multiple contiguous follicles in which the infection is limited to the subcutaneous tissue by thick overlying skin and dense subcutaneous fascia.
  • Carbuncles require incision for drainage and treatment.
cellulites
Cellulites
  • acute infection of loosing connective tissue.
  • Pathogens: B-hemolytic Streptococci or Staphylococci aureus
  • Clinical presentation: redness of skin, swilling and boundless
  • Anaerobic cellulites: crepitation
  • Treatment: antibiotics

incision and draninage

erysipelas
Erysipelas

Skin wound local inflammation

lymphadenitis systemic inflammation

Redness of skin with clear boundary

Edema of proximal lymphanode

Systemic sepsis

abscess
Abscess
  • Characterized by a necrotic center without a blood supply and composed of debris from local tissues, dead and dying leukocytes, components of blood and plasma and bacteria
  • This semiliquid central portion (Pus) is surrounded by a vascularized zone of inflammatory tissue.
treatment
Treatment
  • Incision and drainage
  • Antibiotics
paronychia
paronychia

lateral nail fold trauma redness, pain

suppurative infection

Treatment:

  • incision and drainage
  • removal of the nail: infection extend

deep to the nail

  • antibiotics

Suppurative tenovaginitis, bursitis and infection of palm spaces

infection of the flexor tendon sheath, bursts

and palm spaces, which is usually caused by a

puncture wound to the volar aspect of the digit

or palm
