Sterile scrub
|
|
|
What is the procedure for the sterile scrub
|
Start at incision, turn scrub and work around in circles, discard scrub and use new scrub after making 1 turn around incision (don't want to drag dirt/bact into clean area), alternate hibiclens/alcohol x3, leave last hibiclens scrub on patient for 5 minutes before last alcohol scrub
|
|
|
What is the rule for determining suture size
|
Use the smallest diameter suture that will adequately hold mending tissue to minimize trauma and foreign material
|
|
|
What are the smallest and larges suture sizes
|
12-0 is the smallest, 7 is the largest
|
|
|
What determines flexibility of suture, when would we want a more flexible suture
|
Torsional stiffness and diameter, when ligating vessels/performing continuous suture patterns
|
|
|
What determines suture friction/drag, which characteristic causes more damage, which has less knot security
|
Surface characteristics and coating, rough, smooth
|
|
|
Braided materials are often coated to reduce what property, what is the negative affect of this property
|
Capillarity - fluid and bacteria are carried into interstices of multifilament fibers, infection may persist because neutrophils and MP can't follow
|
|
|
What is 'knot tensile strength'
|
Force (lbs) suture can withstand before breaking when knotted, suture tensile strength SHOULD NOT exceed tissue tensile strength (by much)
|
|
|
What is a traditional cutting needle, what is a negative outcome of using this needle
|
3 cutting edges, 3rd cutting edge is on concave curvature (cuts toward edges of wound/incision), creates notch where suture will lay, may split skin when tying
|
|
|
What is a reverse cutting needle, what does using this needle prevent
|
3 cutting edges, 3rd cutting edge is on convex curvature (cuts away from edges of would/incision), suture less likely to split tissue when tying
|
|
|
What is a taper needle, when are they used
|
Sharp tip that pierces and spreads tissues w/out cutting them, used on easily penetrated tissues (intestine, subcutaneous tissue, fascia)
|
|
|
What are some drawbacks of using 'eyed' needles
|
Pulling double thickness through skin, not used on fragile tissue
|
|
|
What are some properties of swagged needles
|
Suture is continuous with needle, do not use needle as handle when tying knots - weaken crimp, pull out suture
|
|
|

|
Synthetic non-absorbable monofilament (ex 3-0 Prolene)
|
|
|
When performing SQ sutures what type of suture is used
