Surgical Techniques Flashcards
1
Q
What are the proper “surgical scrub” procedures practiced at the site of the skin incision?
A
- clip the hair from around the surgical site
- disinfect the area where the incision will be made (surgical field) by scrubing in a spiral (beginning where the incision will be made, working outward; clean –> dirty)
- use 3 alternating scrubs of betadyne and alcohol (leave final “paint” of betadyne solution)
- use a scalpel with apply digital pressure over the bald to make incision
- make the incision as a single decisive incision (not sawing motion)
2
Q
Describe the approaches for a laparotomy (invasive) procedure.
A
- clip site
- surgical scrub
- incise skin with scalpel
- use rat-tooth forceps to handle skin and abdominal muscle
- elevate abdominal muscles
- cut along linea alba to open abdomen
3
Q
Describe the approaches for a thoracotomy (invasive) procedure.
A
- insert endotracheal tube
- clip site
- surgical scrub
- incise skin with scalpel
- use rat-tooth forceps to handle skin and intercostal muscle
- cut intercostal muscle (between ribs)
note: loss of negative pressure in chest cavity results in collapse of lungs so need to manually infalt lungs or use a mechanical ventilator

9
Q
why may other instruments be inappropriate for the same use? ( scalpel vs scissors)
A
- scissors crush/damage tissue, delaying healing
- scalpel causes less trauma and results in a smoother wound margin, facilitating healing
10
Q
why may other instruments be inappropriate for the same use? (rat tooth vs crushing forceps)
A
rat-tooth forceps prevent excessive crushing of cell
11
Q
