35
Q

Posterior to the bladder (men) and Pouch of Douglas (women)

A

Pelvic

36
Q

What part of the normal abdominal anatomy includes the following?

Heart chambers in the subxiphoid view and PSLA view

37
Q

Abdominal Injuries

Target goal in the absence if TBI is a systolic of ___ to ___ mmHg and in the presence of TBI systolic minimum is ___mmHg

A
  1. 80-90mmHg

38
Q

What is a section of the bowel that is displaced through an open wound and protrudes externally?

A

Eviscerated bowel

39
Q

Treatment of an eviscerated bowel should focus on what?

A

Protecting the protruding segments and providing a moist environment

  • clean or sterile dressings moistened with saline
  • periodically re-moisten
  • Initial dressing may be covered with large, dry dressing to keep warm
  • Psychological support, keep patient calm. Any action that increases intraabdominal pressure can cause more contents to protrude.
