Tetanus Flashcards
T/F
All tetanus spp can cause tetanus infection.
False. Some spp are non-tetanospasmin producing
Elderly Affected are: T cell B cell Immune cells
Immune senescence affects ????
Yes
Skin popping from drug/heroin injection
Wrist
Forearms
Interdigital areas
Under the tongue
(Also check these areas for infective endocarditis)
Why can’t cardiac muscle be tetanized?
Long refractory period due to slow calcium channels (L-type)
Binding of toxins
Already bound- cannot be removed na (4-6weeks)
Unbound- can still be removed
Give meds to address symptoms
Positive spatula test
Normal: gag reflex
Tetanus (+): no gag, involuntary contraction of jaw-> spasm -> biting
Why is culture not reliable?
Anaerobic, cannot grow easily
Toxin causes the disease not the bacteria itself
Shorter incubation, shorter onset, poorer prognosis
Do early tracheostomy bcos of laryngeal muscle spasms
Antibiotic duration
7 days
Immunization
How long to stay in hospi
~4-6 weeks
Give antitoxins/ Ig to perform neutralization of the unbound toxins
Human tetanus Ig
Less anaphylactic reactions than equine antitoxin
Diazepam shorter acting
Why bzd given IV?
Mgmt in ER: Tracheostomy plus NGT
Medications are additive (u do not change the initial med) —> bzd is last to tanggal
But not really often given bcos of propylene glycol—> lactic acidosis
IV bcos:
More rapid action than oral
More titrable and with direct action in the blood
High bp mgmt
Scenario for high bp:
Nicardipine- super lowered bp-> discontinue -> start iv fluids
-di pa tumataas bp-> give vasopressors
short acting, rapid onset, easily titrable
- esmolol
- Propranolol
- use iv form
complications
Matagal maunbound ang toxin—> prolonged ventilator -> VAP
Upright position- para no aspiration
Central-line infections
Septicemia
Pressure ulcer -reduce pressure in sacral area by side to side lying
Stress ulcer
Thrombophlebitis- from diazepam injection; give LMWH and compression stockings
No prophylactic antibiotics for infection
All preventive
Tetanus prophylaxis
Passive- TIG
With Antibodies na: fast action
There is already temporary amnestic response??? (Double check!)
Not immunogenic
Can still receive tetanus containg vax during active infection
Give both active and passive immunization during active infection
