Intraoperative Procedures Flashcards

Which hemostatic agent is derived from oxidized cellulose and works by providing a mechanical matrix for clot formation?

Answer: Surgicel (oxidized regenerated cellulose)

Surgicel is oxidized regenerated cellulose that provides a physical scaffold for platelet aggregation and clot formation.

The surgeon asks for a #15 blade. Which handle is MOST appropriate?

Answer: #3 handle

The #15 blade is designed for the #3 handle and is used for small, precise incisions such as in plastic or ophthalmic surgery.

During laparoscopic surgery, CO2 is used as the insufflation gas primarily because it:

Answer: Is rapidly absorbed and does not support combustion

CO2 is quickly absorbed by the body, is non-flammable making electrosurgery safe, and is exhaled through normal respiration.

A patient in the lateral decubitus position requires an axillary roll. The purpose of this roll is to:

Answer: Relieve pressure on the brachial plexus of the lower arm

An axillary roll placed just below the dependent axilla relieves pressure on the brachial plexus and axillary vessels to prevent nerve injury.

Which of the following describes the correct method for measuring suture before handing it to the surgeon for a ligature?

Answer: Measure from fingertip to elbow (approximately)

A ligature tie is typically measured by the ST from fingertip to elbow (~18 inches) to provide adequate length without excess.

The circulator reports that the patient's temperature has dropped to 35°C during a long procedure. The ST's BEST response is to:

Answer: Prepare warm irrigation fluids and notify the surgeon

Intraoperative hypothermia increases bleeding risk and infection rates; warm irrigation fluids and patient warming measures should be implemented.

When a free tie (ligature) is passed to the surgeon, it should be:

Answer: Stretched between both hands of the ST

The ST stretches the ligature between both hands to present it clearly so the surgeon can grasp the center without tangles.
