Laparoscopic And Robotics Quiz

Patient-specific benefit of laparoscopic surgery:

• Shorter recovery time

• Better clinical outcomes

• Decrease postoperative pain

• Decrease medical risk

Anesthesiologist-specific benefit of laparoscopic surgery:

• Shorter recovery time

• Better clinical outcomes

• Decrease postoperative pain

• Decrease medical risk

Surgeon-specific disadvantage of laparoscopic surgery:

• Increase risk of PONV

• Shorter operating times

• Limited access to patient

• Ergonomics

Sharp, multiport, one-way conduits used to insufflate gas and to guide various specialized surgical instruments:

• Trocar

• Laparoscope

• Veress needle

• Da Vinci Surgical System

True about the use of carbon dioxide in laparoscopic surgeries:

• Highly insoluble in blood

• Oxidizing

• Inflammable

• Nonoxidizing

Primary force/s responsible for much of the physiologic derangement:

• Direct mechanical stress

• Neuroendocrine stimulation

• Both of the above

• None of the above

This position may augment venous return and cardiac filling during pneumoperitoneum:

• Reverse trendelenburg

• Steep trendelenburg

• Left lateral decubitus

• Right lateral decubitus

Intraabdominal pressure produced during pneumoperitoneum is known to:

• Reduce hepatic vein flow

• Increase hepatic vein flow

• Change nothing in the hepatic vein flow

• Disadvantageous during laparoscopic hepatic transection surgery

True regarding nitrous oxide, EXCEPT:

• N2O is avoided due to a potentially greater risk of PONV

• N2O is not known to support combustion during a spark ignition

• During an N2O-based anesthetic, N2O has been shown to accumulate in the peritoneal cavity to combustion levels as early as 30 minutes to as late as 2 hours

• None of the above

Subcutaneous emphysema is the inadvertent introduction of CO2 gas into subcutaneous, preperitoneal, or retroperitoneal tissue leads to trapped gas pockets. The following risk factors for subcutaneous emphysema are all true, EXCEPT:

• Shorter operative times (less than 200 minutes)

• Greater number of surgical ports

• Lower BMI, older patient

• Higher IAP, higher insufflation flow rates
