FLS Modules ACTUAL UPDATED Questions and CORRECT Answers
Terms in this set (141)
warfarin discontinue time 3 days
Laproscopic instruments diameter and length ranges 2-10mm, 30-45cm
hopkins rod lens light has to travel back through the rod to capture the image.
decreasing light in the camera for... decreasing diameter, increasing scope angle (ie 5mm and 30 degree has less light
than 10mm 0 degree)
When is zero degree scope most useful when working in a small area directly in line with the scope and ports, like the
pelvis
how to check fiber optics light connection black dots= broken fibers
why does it fog up? temperature and humidity discrepancy between the OR and body
tools for defogging - FRED antifog (must dry before putting back in)
- put laparoscope in hot water
methods to clean a smudged lens - gently wipe on clean tissue (liver, uterus, bowel)
- remove scope and clean with hot water and gauze
Insufflation gas type and reasoning CO2- readily available, inexpensive, non combustable, warmed and humidified
better
other gasses used in laparoscopy -nitrous oxide
-helium (inert substance)
why is the CO2 warmed and humidified for laparoscopy? statistically significant decreases in body temp and post-op pain
(not significant with surgery lasting <90 mins)
high flow insufflation 10 or more L per minute
preventing loss of pneumo with suctioning keep suction tip below the fluid level
components of the video tower -light source
-camera control unit
-video monitor
-insufflator
most common light source 300W xenon lamp
, troubleshooting steps: gas preOP 1. check that co2 tank is full (gauge may read 'empty' if connected to central CO2
supply)
2. check co2 tank gasket is secured (need a wrench, spare gasket)
3. check that spare co2 tank is available in the OR
troubleshooting steps: image 1. check that the monitor is plugged in and turned on
2. check that all cables are connected correctly and securely
troubleshooting steps: view of operative field is reduced immediately check the insufflator control panel to determine cause
in size
troubleshooting steps: loss of working space: insufflator 1. the patient may not be adequately relaxed or there is a mechanical block of gas
settings: flow
-measured pressure is the same or higher than the preset 2. inspect abdomen for rhythmic muscle contraction and palpate the abdomen for
pressure firmness
3. check port valves to make sure they are open
flow rate = 0 4. check for kinks in tubing and make sure no one is standing on them
troubleshooting steps: loss of working space: insufflator 1. there is a leak in the insufflation circuit
settings: 2. check that the tubing has not become disconnected from insufflator or port
-low pressure and high flow rate 3. check that all valves are closed
4. check all port sites for leaking co2
flow rate = high 5. check for foley catheter bag distention or bowel distention
troubleshooting steps: loss of working space: insufflator 1. make sure that the insufflator power is on
settings: 2. check gas level in the tank
-low pressure and no flow
flow rate = 0
troubleshooting steps: loss of working space: complete 1. check for disconnected power cords, video cables
loss of operative image (blank monitor) 2. check for blown light source bulb
3. check for disconnected light cable (at scope or light source)
(not a fogged camera)
Monopolar electrosurgery circuit electrical surgical unit-->active electrode-->patient tissue-->dispersive electrode
(grounding pad)
low frequency current from wall source to high frequency current at active
electrode
monopolar: tissue coagulation occurs as a result of tissue heating and protein denaturation.
