Schedule 3 Procedures
Cards in this deck (22)
- 1Suture needles Tissue trauma 2:A eyed needle with material double threaded causes the most tissue damage due to a large know being dragged through small tunnel made by needle. Should never be done!
- 2Alternatives to suturing:Sterile stapes - internal and external use
Tissue adhesive - variable setting time, sterile individual packaged vial, for rabbits - 3Blunt point:Needles have round, blunted point
Designed to dissect or penetrate through friable tissue without cutting it
For liver, kidney - 4Spatula point:Flattened body with cutting tip
Designed to penetrate between tissue layers
For opthalmic procedures - 5Reverse cutting:3 cutting edges
Apex of triangle is towards outside of needle
Also cut through tough tissue but cutting point is away from tension line - use for wounds likely to be under tension - 6Regular cutting:3 cutting edges
Apex of triangle towards inside of needle
To cut through tough tissues - muscle and skin - 7Tapercut:Similar to taperpoint but combines a reverse cutting edge tip
Slightly more traumatic as have cutting element
For tendons & dense fibrous tissue - 8Suture needles Taperpoint:Atraumatic, designed to pierce and spread tissues not cut them
For intestines, bladder, s/c tissue and fascia where you need minimum trauma for quick healing - 9Suture needles Parts of needle/needle shapes:Needles come in a variety of shapes.
Swaged needles are usually 1/2 circles - 10Suture needles Parts of needle/needle shapes:Hold body of needle with needle holders for control as passed through tissues
Needle holders should grip body of needle close to shank - 11Suture needles Parts of needle/needle shapes:Point - mostly sharp to penetrate tissues, also blunt
Body - 6main types. Choose most appropriate one
Shank - eye at end or material swaged on - 12Examples of Schedule 3 ProceduresWound closures/stitch ups
Skin mass removal, biopsies
Dental scaling and polishing (digital extraction)
Tx of abscesses, aural haematomas

Held with thumb and fourth finger (MacPhails held in palm) - 17Haemaostats artery forcepsTo occlude blood vessels (after 2min)
Choose smalles appropriate size
Applied to vessels before cut or once incised when bleeding seen (tips)
Tied off with 2/3m suture or clamping/twisting/pulling small vessels - 18Scissors (Mayo and Metzenbaum) Curved or straightUsed to cut skin and suture material
Used for cutting or blunt dissection
Held in right hand with thumb and ring finger (to first joint)
Index finger rests along blade for stability, middle finger wraps around ring - 19Tissue ForcepsTraumatic to tissues
Useful for holding tissue going to be excised
Also for holding skin edges but should be applied to dermis rather than skin surface - 20Thumb Forceps (Rat tooth & Atraumatic)Held in a pencil grip and balanced across hand
Should be used as gently and infrequently as poss - 21Scalpel and handleScapel blade incises skin
Scalpel handle used to hold blade
Held in pencil grip, fingertrip grip or (rarely) a palm grip
Hold positively, firmly with controlled pressure
Used to make a stab incision into abscess
Used needleholders to remove - 22Towel Clips (Crossover & Backhaus)Tips placed downwards towards tissue
