Suture Sheet: Key Facts, PRISM Flashcards
(32 cards)
how are sutures classified?
according to size (They can range from 0-0 (very thick) to 9-0 (extremely thin).
capsule closure: suture
2-0 or 3-0 Vicryl
subcutaneous closure: suture
3-0 or 4-0 Vicryl
skin: suture
4-0 Nylon or Prolene
when are sutures removed? why?
10-14 days;
because at this point the tensile strength of the wound equals the tensile strength of the suture.
suture (non-absorb/absorb) for DEEP CLOSURE
absorbable
what does it mean to be CHROMIC
*treated with CHROMIC SALTS –> to inc strength and decrease hydrolysis;
natural, absorbable suture material like pig collaen, sheep intestine, catgut
digestion: absorbable, NATURAL suture materials
20 days, digested by LYSOSOMAL ENZYMES
Vicryl tensile strength at 14 days
65% tensile strength
digestion: VICRYL
Hydrolyzed (to CO2 and H20) in 80-120 days
digestion: RAPID vicryl
Hydrolyzed in 42 days; loses strength in 7-10 days
VICRYL plus: describe unique feature
Coated with broad spectrum antibiotic Triclosan (also found in toothpaste)
digestion: DEXON
Hydrolyzed in 100-200 days
digestion: PDS
Hydrolyzed in 90 days
PDS tensile strength at 14 days
70% tensile strength
digestion: MAXON
Hydrolyzed in 180 days; Longest lasting absorbable (“Max”-imum)
longest lasting absorbable material
MAXON (polyglyconate)
Monocril tensile strength at 14 days
20-30% tensile strength
digestion: MONOCRIL
Hydrolyzed in 90-120 days
suture type for superficial closure/skin sutures
non-absorbable
digestion: SILK
actually very slowly absorbed (hydrolyzed in 1 year)
Silk tensile strength
very low tensile strength
weakest suture material
COTTON / LINEN
highest knot slippage rate
NYLON; (Ethilon, Surgilon)
monofilaments are at a higher risk of knot slippage
