Flashcards in Surgical infection Deck (13):
1

Prophylactic antibiotic for biliary tract surgery with active infection

1. ampicillin sulbactam
2. piperacillin sulbactam
3. ticarcillin sulbactam

2

Prophylactic antibiotic for colorectal, obstructed small bowel

1. cefazolin + metronidazole

3

Types of SSI

1. incisional
2. organ/ space infections

4

Treatment of incisional SSI

1. incision and drainage
2. without antibiotics - except in SIRS or cellulitis

5

Characteristic of primary microbial peritonitis

1. diffuse tenderness and guarding without localized findings
2. aabsence of pneumoperitoneum
3. presence of >100 wbc
4. single morphology of microbe

6

Treatment of primary microbial peritonitis

antibiotic therapy for 14 to 21 days
removal of indwelling devices

7

Cause of secondary microbial peritonitis

contamination of the peritoneal cavity due to perforation or severe inflammation and infection of an intra abdominal organ

8

Treatment of secondary microbial peritonitis

1.source control
2. resect or repair diseased organ
3. debridement of necrotic, infected tissue
4. administer antibiotics

9

Cause of tertiary/ persistent peritonitis or postoperative peritonitis

leakage from a GI anastomosis or intra abdominal abscess in whom standard therapy fails

10

Treatment of tertiary peritonitis

CT guided percutaneous drainage of intra abdominal abscess

11

Hemodynamic critera of cardiogenic shock

1. SBP < 90 mmHg for at least 30 mins
2. Reduced cardiac index < 2.2
3. elevated pulmonary artery wedge pressure > 15 mmHg

12

What percentage of the blood volume is in the splanchnic circulation

20%

13

This best describes hemodynamic response to neurogenic shock

increased cardiac index
unchanged volume capacitance
