Which suture is contraindicated in infected wounds due to its multifilament braided structure?
Answer: Silk
Silk's braided multifilament structure can harbor bacteria, making it contraindicated in infected or contaminated wounds.
A circular stapler (EEA) is used primarily for which type of anastomosis?
Answer: End-to-end bowel anastomosis
The end-to-end anastomosis (EEA) circular stapler creates a circumferential staple line for bowel-to-bowel reconnection.
What is the absorption mechanism of synthetic absorbable sutures like Vicryl?
Answer: Hydrolysis
Synthetic absorbable sutures like Vicryl are absorbed by hydrolysis, where water breaks the polymer chains.
Which needle body shape is best suited for suturing in deep, confined cavities?
Answer: 5/8 circle
A 5/8 circle needle requires less wrist rotation, making it ideal for deep, confined spaces like the pelvis or bladder.
The TA (thoracoabdominal) stapler applies staples in what configuration?
Answer: Double staggered rows
The TA stapler applies two staggered rows of staples simultaneously to ensure a secure, hemostatic closure.
Nylon suture (Ethilon) is classified as which type?
Answer: Non-absorbable synthetic monofilament
Nylon (Ethilon) is a non-absorbable synthetic monofilament suture used for skin closure and microsurgery.
What is the purpose of coating Vicryl suture with polyglactin 370 and calcium stearate?
Answer: To reduce tissue drag and improve handling
The coating on Vicryl reduces tissue drag, allowing the suture to pass smoothly through tissue and improving knot rundown.
