Major components of medical video imaging include:
Fiber optic light cable, Camera Control Unit (CCU)
Special considerations when using a endoscopic light source are:
Place in "standby" mode, do not turn on until light cable is connected to the telescope, set according to manufacturer's parameters
00:51

Special considerations when using insufflation (establishing a pneumoperitoneum)
Always have a backup tank available, position at the level of the patients heart or higher to prevent gases from contaminating the device, make sure alarm is on and audible, maintain pressure under 12 mm/Hg
Advantage of endoscopic surgery versus open surgery
Smaller incisions
Special considerations when using laparoscopic instruments
Scrub should inspect more closely because of unapparent defects that may not be apparent with casual observation, focus on insulation because of risk for thermal burns if not intact
Special considerations for patient undergoing MIS/Endoscopic Surgery
Previous incisions (Hasson minilap) that may require additional sterile supplies, hx of DVT, consent for possibility of open procedure, voiding to empty bladder and prevent puncture during trocar placement/unnecessary catheterization
Correct fluid management procedures in MIS
Monitor overload of IV/irrigation fluids dispensed and returned during procedure (prevent hypervolemia/fluid overload)
Mechanical Methods of Hemostasis
Manual pressure (sponges), hemostatic clamps, sutures, staples, clips, ligatures, and/or pledgets
What is a ligature?
Also known as a tie, strand tied around a blood vessel to occlude bleeding; large vessels may require transfixion suture (crosscriss stitch)
What is a pledget?
Non-absorbable suture support used when possibility of sutures tearing through tissue
Where is a pledget most commonly used?
Vascular closure, septal repair, heart repair and hepatic repair
What is bone wax?
A mixture of beeswax, isopropyl, and a softening agent
