6 Halstead principles

1. gentle tissue handling2. hemostasis3. aseptic technique4. preserve blood supply5. eliminate dead space6. Appose tissues with minimal tension

2

grips for scalpel handling

pencil--accurate for short, delicate maneuversfingertip--max length with greatest accuracy, stability

3

four motions of cutting with scapel blade

1. slide--precise depth, length and control2. press--stab incisions3. sawing--continuation and cut without removal/reinsertion of blade4. scraping--separate tissue layers

4

three forces used when cutting with scissors

1. close2. shear3. torque

5

grip used with scissors

tri-pod

6

T/FCutting tissue with the portion of the blade near the fulcrum results in greater crushing injury

TRUEUSE TIPS FOR LESS CLOSING FORCE AND MORE SECURE STABILITY OF TISSUE

7

needle hold names for those that cut and don't cut

Mayo-Hegar---don't cutOlsen Hegar--cut

8

suture tage recommendations for synthetic material v gut

suture tagessynthetic: 3 mmGut: 6 mm

9

four grips for manipulating a needle holder

1. tri-pod (thumb-ring)2. thenar3. palmed 4. pencil (castro veijos)

10

strongest grip in a ringed instrument

palmed--provides the greatest needle pressure and control in dense tissue and provides maximum wrist rotation

11

3 types of forceps

1. crushing--Allis, Babcock, Kocher2. noncrushing--Doyen, Statinsky3. hemostatic--Halstead, Kelly, Crile, Carmalts

12

list non penetrating instruments

1. lorna2. ednas3. allis

16

the blood supply in the wound edge is inversely proportional to what...

the blood supply in the wound edge is inversely proportional to the wound closure tension

17

benefits of a continuous pattern suture

quickerdistributes tension evenly along entire length of wound

18

inverting continuous patterns

connell (into lumen)cushinglembert

19

T/Fpurse string sutures are inverting

TRUE

20

5 principles of knot tying

1. simplest secure knot for suture used to minimize knot volume2. avoid friction3. use appropriate tension4. pull suture ends in opposite direction, horizontal and with even tension5. never grasp suture with needle holders

21

where is the weakest point in a suture line or ligature

practically always the knot
