Endoscopic and Minimally Invasive Surgery (MIS)
Three things to know about endoscopic light source Correct Ans - 1-DO NOT turn on the
light source until the light cable is connected to the telescope.
2- When not in use, the light source should be placed in "standby" mode.
3- Always set your parameters according to the manufacturer's instructions.
What is Pneumoperitoneum? Correct Ans - The process of insufflating the abdominal
cavity with CO2
Name 4 precautions when preforming pneumoperitoneum. Correct Ans - 1- always have
a back up tank of CO2
2- The insufflator should be positioned on the cart at the level of the patient's heart or
higher to prevent intra-abdominal fluids or gases from contaminating the device.
3- Make sure the alarms are on and working correctly to display the CO2 pressure and
supply level
4- Maintain intra-abdominal pressure under 12 mm/Hg in adult pts to reduce the risk of
systemic hemodynamic changes
True or false. Electrical current can escape through any break in the insulation, and thermal
burns can result from these breaks. Correct Ans - true.
List the three steps in cleaning endoscopic instruments. Correct Ans - 1. clean off the
external debris during the case with a moistened sponge.
2. flush the channels with sterile water to remove gross soil during surgery.
3. Test scissors for sharpness prior to sterilization.
Why is sterile water recommended during endoscopic instrument cleaning. Correct Ans -
Because saline water can cause erosion of metal surfaces.
List FOUR things the circulating nurse should focus on for a patient undergoing endoscopic
or MIS. Correct Ans - 1- Previous incisions that may alter the trocar insertion technique.
2- History of a DVT
3- Consent to include the possibility of an open procedure.
4- Voiding prior to surgery. This helps avoid puncturing the bladder during surgery and
decreases catheriztion
What are TWO risks involved with fluid management in MIS Correct Ans - hypothermia
and fluid overload
List two ways to acheive correct fluid management for the patient during MIS Correct Ans
- 1- monitor overload of IV and irrigation fluids to avoid hyponatremia and hypovolemia
2- monitor the amount of irrigation fluids dispensed and returned during the procedure
