surg 1 study guideligate, suture, and close tissue - ANS-The primary use for suture is essentially to
ease of tying - ANS-The ideal suture material is one that has handling characteristics such as
class III suture - ANS-Nonabsorbable sutures are strands of material that effectively resists
enzymatic digestion in living animal tissue. The USP categorizes nonabsorbable surgical suture
into classes. A suture composed of monofilament or multifilament metal wire would be a
is nonabsorbable, has good tensile and knot strength, and is the appropriate diameter for the
tissue - ANS-The surgeon needs a suture material that will not degrade over time but becomes
encapsulated and supports a tissue structure that will continue to be exposed to pressure and
stretching forces throughout the patient's life. These physical properties are best described by a
suture that
polypropylene - ANS-A surgeon was teaching the new residents as he closed the muscle and
fascia layer following an open cholecystectomy. He stated that he liked the tensile strength of
this monofilamented synthetic suture, but it was hard to manage with its memory and
slipperiness and normally needed six surgeon's knots to hold. He was using
silk - ANS-A surgeon explains his justification for his suture choice to the new perioperative
nurse in the scrub role. He prefers to suture his intestinal anastomosis with a suture that has
multiple filaments braided together because it ties well and holds the knot, which tightens when
the thread absorbs the tissue fluids. He also needs a strand that is easy to see and only needs
to retain its tensile strength for about 1 year, at which time the intestinal junction will be healed,
even though this suture is considered nonabsorbable. He will ask the nurse for a 24-inch 4-0
polyglactin - ANS-male patient had a vasectomy in his urologist's office. The small incision was
closed with sutures that are synthetic and will "dissolve and fall out" after 2 to 3 weeks. As the
procedure ended, he heard the doctor ask the nurse for 5-0
Swaged - ANS-veteran perioperative nurse remembers a time when all suture needles had
eyes, and she even had her own needle rack. She hand threaded all sutures according to the
surgeon's preference. The newer sutures were originally called "atraumatic" sutures because
they did not double back through a needle eye and cause tissue trauma during pulling or
suturing through the tissue. Today, we call this manufacturing process of connecting the suture
thread to the needle
Double armed - ANS-creating a vascular anastomosis, the surgeon will typically suture one-half
of the anastomosis with one-half of the suture and the other half of the anastomosis with the
