Intraoperative Surgical Procedures Flashcards

During a robotic-assisted prostatectomy, the surgical first assistant's primary role at the bedside includes:

Answer: Exchanging instruments, managing specimen extraction, and assisting with stapling

The bedside assistant in robotic surgery exchanges instruments, manages suction/irrigation, and performs tasks the robot cannot do autonomously.

Which tissue layer must be closed separately during a Pfannenstiel incision closure to prevent hernia formation?

Answer: Anterior rectus sheath (fascia)

The anterior rectus sheath is the primary load-bearing layer; failure to close it properly leads to incisional hernia.

A patient under general anesthesia has a sudden rise in end-tidal CO2 and body temperature during orthopedic surgery. The surgical first assistant should:

Answer: Immediately notify the anesthesia team and surgeon of possible malignant hyperthermia

Rising ETCO2 with hyperthermia during anesthesia is a classic early sign of malignant hyperthermia, requiring immediate team notification and dantrolene administration.

When using a harmonic scalpel (ultrasonic energy device), the surgical first assistant should avoid:

Answer: Activating it while the blade is in contact with metal clips or other instruments

Activating an ultrasonic device while touching metal can transfer energy to unintended structures, causing burns or device damage.

During a hepatic resection, the Pringle maneuver is used to control inflow. This maneuver involves clamping the:

Answer: Portal triad (hepatoduodenal ligament containing portal vein, hepatic artery, and bile duct)

The Pringle maneuver clamps the hepatoduodenal ligament to occlude portal vein and hepatic artery inflow, reducing hepatic hemorrhage.

When passing a suture loaded on a needle holder to the surgeon, the surgical first assistant should present it in which orientation?

Answer: Needle in supinated position with the curve oriented for immediate use by the surgeon's dominant hand

Presenting the needle with the curve properly oriented for the surgeon's dominant hand allows immediate use without repositioning.

In vascular surgery, which action by the surgical first assistant best prevents intimal injury when handling a vessel graft?

Answer: Handling only the adventitial surface and avoiding forceps on the intimal surface

Intimal injury promotes thrombosis; grafts should be handled by the outer adventitia only to preserve the inner lining.
