What are available laparoscope diameters? 2-10mm
What degree scope is best for a field of view in-line with Zero degree
a port?
What is the most commonly used light source? 300 W Xenon lamp
What if there is initial low pressure and high flow rate at There may be a leak in the insufflator circuit. Check all connections.
entry?
Benefits of Monopolar energy. Tissue heated quickly. Less thermal spread/coagulation.
Monopolar voltage/frequency Low voltage, High frequency
What does coagulation mode do? Rapid surface heating with shallow depth of necrosis. intermittent wave form with
higher voltage.
What are some risks of monopolar energy? Current can be diverted through unintentional pathways leading to inadvertent
tissue injury. To avoid this, do not use "hybrid" ports that mix plastic with metal.
How does a grounding pad avoid injury with monopolar Grounding pads help avoid capacitative coupling. This happens when two
energy? conductors are separated by an insulator and the passive electrode stores energy
that can be released with tissue injury. The grounding pad inhibits the passive
electrode from storing energy.
Benefits of bipolar energy. - Lower risk of inadvertent injury.
- Produces less thermal spread and necrosis.
- No grounding pad necessary.
- Works in a "wet" operative field.
Risks of bipolar energy. May cut patent blood vessels before adequate sealing. Device will not work if
there is metal between the jaws.
Risk of ultrasonic dissection (harmonic). The active blade can inadvertently injure something due to high frequency
(50mHz).
Does aspirin need to be discontinued day of surgery. No
How to best enter a patient with bowel obstruction. Direct visualization.
, Cut vs Coag Cut: Heats tissue quickly to convert cell water to steam, lysing the cell.
Coag - Heat more widely dispersed, less cutting.
Benefits of "Cut mode" - Low voltage
- High frequency
- Continuous waveform
- Heats tissue quickly. Cell water converts to steam and causes the cell to
lyse/explode.
Benefits of "Coagulation mode" - High voltage
- Low frequency
- Intermittent waveform
- Rapid tissue heating, shallow depth of necrosis.
- Non-contact. Relies on sparking to tissue.
What is direct coupling? When a monopolar instrument is in direct contact with another metal instrument
and energy is transferred.
What are other dangers of energy use besides direct and - Current diversion
capacitative coupling? - Narrow return circuit.
Bipolar seals vessels up to ___ mm in diameter. 7mm
Ultrasonic coagulation shears seal vessels up to ___ mm 5mm
in diameter.
Benefits of Ultrasonic Coagulation shears. - Combo compression and friction.
- One active blade.
- Monopolar capabilities with the active blade.
- No capacitative coupling.
- High power (Max): Cut
- Low power (Min): Coagulation
How many days prior to surgery should Warfarin be 3 days
discontinued?
ASA 1 Classification Healthy adult
ASA 2 Classification Mild to moderate systemic disease
ASA 3 Classification Severe systemic disease that limits patient activity. May or may not be related to
reason for surgery.
ASA 4 Classification Severe systemic disease that limits patient and are life-threatening with or without
surgery.
ASA 5 Classification Little chance for survival. Surgery is a last resort (resuscitative efforts).
Which ASA classes may not be appropriate for ASA 4 & 5. The body may not handle decreased venous return and need for
laparoscopic surgery? hyperventilation.
