Contraindications for Plebotomy
Cellulitis Trauma Burns Radical Mastectomy on that side AV Fistula Hematoma That arm already has an IV
Phlebotomy vs Venipuncture
Plebotomy is the process of making an incision in a vein with a needle. The procedure itself is known as Venipuncture.
Complications of Venipuncture
Cellulits Plebitis Thrombosis Laceration of nearby Artery Hemorrhage or Hematoma Syncope (at the sight/thought of blood)
Phlebitis
Infection of a vein

Purple Top (EDTA)
Full Blood Count (CBC)
A1c
Malaria + Sickle Cell
Electrophoresis
These tests require a purple cap tube and each one requires its own vial and blood needs to be sent to the lab asap:
Tacrolimus ESR Lead Testing Chromosomes Renin and a bunch more.
Tacrolimus
Immunosuppressant.
Blood levels are used to guide minimum dose needed to suppress immune function so as to minimize side effects.
Pink Cap
Cross Match
This Tube must have FOUR patient IDENTIFIERS and be SIGED
Grey Cap
Blood Glucose
Lactate
Ethanol
Blood stops flowing during venipuncture
Vein Collapsed.
Withdraw catheter and get another vein
Can you perform venipuncture on an artery?
Never
You can get arterial gases and arterial testing but these require different equipment.
Catheterization Indications
Output measurement (always with IV therapy)
To obtain a sterile urine sample (instead of a clean catch - this would not necessarily be a Foley, could use a strait cath for this)
Imaging of the urinary tract (running in dye/isotopes to be followed by Xray/CT)
Bladder Irrigation (w/saline or meds ex: Amphotericin B irrigation for fungal UTI)
Intermittent decompression of Neurogenic Bladder (again, unless bed-ridden, this will be a strait cath, possibly even self inserted)
Tidiness in managing bed ridden patients (I should think this somewhat controversial as it is not an insignificant infection risk with pseudomonas and
Common Nosicomial Catheterization Caused UTI pathogens
Usually it’s E.Coli or Enterobacteria - as anywhere but
Nosicomial Bugs are notoriously resistant to antibiotics and several can form biofilms on the tubing and in the bag. Also, many nosocomial UTIs occur when urine is alkinized from drugs or dietary changes.
Proteus Mirabilis Candida Albicans (esp ICU pts)
Pros + Cons of Plaster Splints
*Easier to mold than fiberglass, but messier
Mess cleans up with water though, not
solvent
*Plaster curing is an exothermic process and\
could potentially cause Pt a burn if COLD
water were not used to hydrate plaster
*Plaster is heavier than fiberglass and will soft-
en if it gets wet but
*Plaster will ‘wick’ underlying moisture off a
wound, which keeps things nice and
dry beneath, whereas fiberglass will
incubate bugs in moisture.
So…. Mix plaster with COLD water and keep i DRY!
Merits of Fiberglass
Its light weight, hard and the cast itself is waterproof, though the pad beneath is not so moisture will get trapped between skin and cast, no real way around that.
It cures quickly, as soon as it’s exposed to air, so you have to work fast
Its a resin + you need to wear gloves while applying and protect pts skin from the uncured fiberglass
Indications for Casting + Splinting
To immobilize simple NON-DISPLACED fractures, soft tissue ligament sprains, dislocations + strains
Straighten congenital abnormalities like club foot
Manage ankle ulcers + charcot foot
Casting Contraindications + Complications
Don’t cast early, let swelling ebb then cast 4+ days out.
Don’t cast over infection or wounds - you might get away with a casting window but think that through carefully
No Matter what you do, Cast Dermatitis may result from no air flow. Blow COOL AIR under the cast with a hair dryer. NO BABY PWD or itching beneath the cast with a knitting needle - you might scratch and cause infection!
Prevent compartment syndrome by
1) not casting until swelling is done
2) Bi-Valving the cast to allow for expansion
DVT from lack of movement - get Pt up and around and contracting that calf muscle inside his cast to prevent clot formation.
Pressure Sores + Nerve Damage: You must PAD bony prominences well and ensure that you mold the cast with your palms + not your finger-tips as tips make indentations that might press down on the skin and/or nerves
head of fibula - perineal nerve is a common site of nerve pressure damage.
Hematoma Block?
When fracture ends are displaced blood vessels are broken and bleeding between the broken bones occurs - this is the hematoma
To anesthetize that area (usually the wrist: radius or ulna) 7-8 ccs of LIDOCAINE is injected directly into the hematoma from various directions.
Then the fracture is reduced: pulled out and repositioned. This would obviously be very painful without the anesthesia.
Sugar Tong Splint For? Describe:
For DISPLACED Colles Wrist Fracture : Distal Radius fracture with posterior radial displacement. Also called Dinner Fork Fracture.
Also for fractures of the ulnar and or radial shafts
Splint extends from just proximal of the Metacarpal joints on the dorsal hand, around the medial aspect of the elbow and back to the
palm opposite the metacarpals.
Fingers need to be able to bend at the metacarpals. Thumb has FULL range of motion
