CFA Tissue Retraction & Exposure 2

Question 1

Which retractor is most appropriate for maintaining exposure of deep pelvic structures during prolonged procedures?

Accepted Answer

Balfour retractor

Answer

The Balfour retractor is a self-retaining abdominal retractor designed to maintain wide, sustained exposure of deep pelvic structures.

Question 2

When retracting the liver during an upper abdominal procedure, the first assistant should apply pressure in which direction?

Accepted Answer

Upward and laterally

Answer

Retracting the liver upward and laterally elevates it away from the operative field while minimizing the risk of parenchymal tearing.

Question 3

A first assistant notices the surgical team is using a malleable retractor against a major vessel. The priority concern is:

Accepted Answer

Pressure-induced vascular occlusion or injury

Answer

Sustained pressure from a retractor against a major vessel can cause occlusion, thrombosis, or direct vascular injury.

Question 4

The Weitlaner retractor differs from the Gelpi retractor primarily in that it:

Accepted Answer

Has blunt rather than sharp prongs and a ratchet lock

Answer

The Weitlaner retractor has a ratchet locking mechanism and is available with blunt or sharp prongs, whereas the Gelpi retractor uses sharp, curved prongs for tissue penetration.

Question 5

During a procedure, the surgeon requests 'more retraction' on a muscle belly. The first assistant should:

Accepted Answer

Apply steady, gradual force while monitoring tissue response

Answer

Steady, gradual retraction force prevents muscle tearing and ischemia while achieving the needed exposure.
