What is new in management of Surgical Infection Prof. Ravi Kant
Slide 2-

Contents: Introduction Types of surgical infections Definition of SSI Types SSI Recent management of SSI sepsis Peritonitis
Slide 3-

Soft tissue/wound Infictions. Third most reported nosocomial infections 16% of all reported nosocomial infections Most common surgical patient nosocomial infection (38%)
Slide 4-

2/3 involved surgical incision 1/3 deep structures accessed by incision Deaths in patients with nosocomial infections—77% related to infection. Soft tissue/wound Infictions. EWMA Journal 2005; 5(2): 11-15.
Slide 5-

Introduction < 1900= 70-80% mortality for wound infection >1900: Ignaz Semmelweis and Joseph Lister = antiseptic surgery
Slide 6-

Introduction Surgery, trauma, non-trauma local invasion can lead to bacterial insult. Once present, bacteria, initiate the host defense processes. Inflammatory mediators (kinins, histamine, etc.) PMN’s arrive, etc.
Slide 7-

Introduction Surgical infections surgical wound itself or in other systems in the patient. They can be initiated not only by “damage” to the host but also by changes in the host’s physiologic state.

Sepsis Sepsis: Commonly called a "blood stream infection.“ The presence of bacteria (bacteremia) or other infectious organisms or their toxins in the blood (septicemia) or in other tissue of the body.
Slide 65-

Sepsis Sepsis may be associated with clinical symptoms of systemic (bodywide) illness, such as fever, chills, malaise , low blood pressure, and mental status changes. Sepsis can be a serious situation, a life threatening disease calling for urgent and comprehensive care.
Slide 66-

Sepsis, Septic shock Signs of: Increased C.O. Altered O2 SATURATION. Metabolic acidosis (usually) Can lead to ---Death.

The aim Sepsis is condition diagnosed on the bases of clinical & laboratory parameters increased level of inflammatory mediators reflects global dysregulation of immune response Examine the latest evidence for the use of immuno-modulating drugs obtained from human clinical trials
Slide 70-

immune response is multi-faceted Aim : Eliminate invading object Maintain homeostasis Limit tissue damage

Sepsis And host response More than adequate or Inadequate.
Slide 72-

Inadequate Host response Stimulation by Levamisole Pro inflammatory Cytokine interferon y Anti- prostaglandins (immunosuppressive mediators

Slide 75-

Severity assessment PAC- initially Ultra low frequency ossillations in CO/global end diastolic vol -severity high Lactate levels –good severity predictor Low exogenous clearance – very early predictor of mortality C reactive protein – high risk of organ failure/ too slow to monitor
Slide 76-

Management of Sepsis Hemodynamic, respiratory stability Source control in sepsis Early enteral feed/intensive insulin therapy stress ulcer prophylaxis, and deep vein thrombosis Daily hemodalysis – better survival

Early goal-directed therapy (EGDT) Oximetric central venous catheters were placed to measure central venous pressure (CVP) & CvO2 500-mL aliquots of isotonic crystalloid were given by bolus infusion to achieve a central venous pressure greater than 8 mm Hg. Rivers E, Nguyen B, Havstad S, et al. Early goal-directed therapy in the treatment of severe sepsis and septic shock. N Engl J Med 2001;
Slide 78-

Early goal-directed therapy (EGDT) Mean arterial pressure was maintained at 65 mm Hg or higher with vasopressors. If the CvO2 saturation was still less than 70%, blood was transfused to a hematocritof 30. If the CvO2 saturation was still less than 70%, dobutamine was started. Rivers E, Nguyen B, Havstad S, et al. Early goal-directed therapy in the treatment of severe sepsis and septic shock. N Engl J Med 2001;
