Q

The first scope size is determined by the size of

A

The first scope size is determined by the size of the port incision – if the surgeon makes a very small incision and uses a 5mm port, then you would choose a 5mm scope to start

10mm 0 degree
10mm 30 degree
5mm 0 degree
10mm 30 degree

Q

how would you check the placement of a needle in a laproscopic surgery

how do you check for laminar flow and the make sure that the needle is not in a vessel

A

10cc of saline in a syringe is twisted on to veress needle to check placement

The surgeon will aspirate first – to check that the needle is not in a vessel and then inject saline – to check that the flow is laminar

21
Q

after the syringe has been removed, the placement of the needle of confirmed what would the the assistant do next in a pneumo lapro surgery

A

The syringe is removed and the assistant places the insufflation tubing onto the veress needle

22
Q

A Veress needle

A

is a spring-loaded needle used to create pneumoperitoneum for laparoscopic surgery. Of the three general approaches to laparoscopic access, the Veress needle technique is the oldest and most traditional.

23
Q

if the veress needle is not deep enough or into a organ you will most likely see a pressure that is

what would you do to amend this

A

too high

pull back and see if the pressure drops

24
Q

what is low flow with a veress needle and what is high flow

A

The veress needle only allows low flow (3)so can ask for high flow (40)

25
Q

why do we use Co2 for a pneumo laparoscopic surgery

A

Inexpensive

Non-combustible

Very soluble and reduces risk of gas embolism

26
Q

what is a a gas embolism

A

Gas embolism:

blood vessel blockage caused by one or more bubbles of air or other gas in the circulatory system.

27
Q

what does it mean to say that the patient is “tight” during a laproscopic surgery

A

If the pressure is above the preset number – the patient is “tight”

28
Q

if the pressure drops during pneumo surgery it could be due to

A

Tubing not engaged properly

Ran out of CO2

Port is leaking or open

29
Q

what is the preset pressure

A

the preset pressure (15),

30
Q

what is the trocar usually used

A

a 10 or 12mm port with trocar is placed

if small 5mm

31
Q

cleaning the camera scope before introducing it to the port helps reduce

A

condensation

32
Q

how can you adjust the focus of a camera

A

Focus can be adjusted with the dial on the camera head

33
Q

this part of the trocar must always be within the view of the surgeon

A

The surgeon will need to see the tip always!

34
Q

for a 0 degree trocar the camera must be pointed

A

Camera head is up
Light cable is pointing up (for 0 degree)

direction the light cord is pointing is the direction of view

35
Q

how can you prevent the camera from fogging

A

To clear up the “foggy” view, take out the camera and either wipe the scope on the FRED sponge or dip it in the FRED solution. The best way is hot water (in a thermos) if available; followed by tapping the excess off

36
Q

before dipping the camera in the fred solution you must

A

Wipe the scope clean with lab sponge before dipping in FRED

37
Q

internal cleaning of the camera can be done by

A

Clean scope by briefly touching liver (never the intestines)

38
Q

FRED stands for

A

FRED stands for Fog Reduction Endoscopic Device

39
Q

why do you hold the scope from the top

A

Holding the scope from the top allow you to use the focus dial with one hand

40
Q

The scope should be looking between

A

The scope should be looking between the 2 ports that the surgeon is using

41
Q

Keep the surgeon’s instrument in the

A

Keep the surgeon’s instrument in the middle of the screen

42
Q

If blood hits your scope –

A

do nothing UNLESS the surgeon asks you to clean the scope -

43
Q

who can be a first assist

A
  • A PHYSICIAN ASSISTANT
  • AN MD/DO
  • AN RNFA
  • Not an NP
44
Q

what can PAs do under supervision

A
  • Incisions
  • Placement of laparoscopic and robotic trocars
  • Cutting/tying VESSELS
  • Drilling/sawing/malleting BONE
  • Laparoscopic stapling/clipping/cutting of tissue/vessels
  • Placement of drains
  • Any invasive action
45
Q

without supervision PAs can

A
  • closing all incisions
  • sewing in drains
  • Stapling skin
  • Steristrips/dressings
  • removal or placement of bladder catheter
  • whatever needs to be done before the patient moves off operating table
46
Q

Maintains Sterile Field

Control of Surgical Instruments

PASSES STERILE INSTRUMENTS AND EQUIPMENT TO SURGEON OR ASSISTANT SURGEON

RESPONSIBLE FOR KEEPING COUNT OF SUTURE NEEDLES AND LAP SPONGES ETC

A

surgical tech

47
Q

what does a circulation nurse do

A
  • Monitors Sterile vs Non-Sterile Field
  • Non-Sterile person
  • Provides Scrub with whatever the Scrub wants!
  • Assists Anesthesiologist
  • Once patient is on the OR table, will ready the patient for surgery
48
Q

how do circulating nurses prepare pts for surgery

A
  • Placement of EKG leads
  • BP cuff
  • Finger oximeter
  • Sequential Devices for legs
  • Blankets for warmth
  • Placement of foley catheter
