Or
2. Increased destruction (ITP, drug induced)

Intrinsic path; PTT test
Factors V, VIII, IX, X, XI
Hemophilia B is a deficiency in...
Factor IX
X-linked recessive
Management of hemorrhage in hemophiliacs.
1 unit Factor VIII/kg = 2% rise

7. Thin mandibular inferior border (panorex)
ASA I
Normal healthy
ASA II

(ex. SCA)
ASA IV
Severe systemic disease that is a constant threat to life.
ASA V
Moribound patient not expected to survive with or without the operation
ASA VI
Brain dead patient; organ donor
What is the ASA class of an asthmatic and SCA patient respectively?
ASA II
ASA III
Seizure management
Position patient to prevent injury
Post-ictal airway support: suction airway, towel under shoulders, oxygen as needed.

Seizure >5 minutes, activate EMS
Ritalin, Concerta, Adderall, Strattera and Clonidine are all common ADHD medications.
Which ones interact with sedation medications?
Adderall: caution with meperidine.

Clonidine: pontentiates CNS depressants.
True or False:
Males are 3-4 times more likely to be affected by Autism.
TRUE.
Females are more likely to have mental retardation when affected.
What are the key differences between Autism and Asperger's?
Autism: social, language and cognitive impairment.

Asperger: social impairment only
Name some common medications for ASD.
Abilify, Prozac, Ritalin, Concerta, Risperdal, Tegretol

Note: Risperdal (anti psychotic, anti aggression) & prozac potentiates CNS depressants. Caution with sedations.
Name an example of a syndrome caused by chromosomal anomaly.
Down syndrome

Trisomy 21-sporadic mutation resulting in extra copy of chromosome.

Risk increases with maternal age.
True/false: those with the mosaic variant of trisomy 21 are higher functioning.
True. Up to 3% may have this variant where not all cells are equally affected.
