A multivariate analysis identified five independent risk factors for difficult face mask ventilation:

(1) age older than 55 years
(2) body mass index (BMI) greater than 26 kg/m2
(3) presence of a beard
(4) lack of teeth
(5) a history of snoring

2

Difficult tracheal intubation has been variously defined by

(1) the time taken to intubate
(2) the number of attempts
(3) the view at laryngoscopy
(4) the requirement for special equipment

3

when are the the majority of obstetric general anesthetics administered for emergency deliveries?

often during off-hours;

these anesthetic procedures may be conducted by inexperienced anesthesia providers with less proficiency in difficult airway management.

4

larynx visualization - various strategies can minimize this problem, the most important is

optimizing the pts position

5

Comprehensive airway evaluation, prophylactic administration of nonparticulate antacids, and use of regional anesthesia decrease

the risk of aspiration.

6

General anesthesia may be unavoidable occasionally; therefore, awake intubation may be indicated in women in whom

airway difficulties are anticipated.

7

At term gestation the pregnant woman who requires anesthesia should be regarded as having an incompetent

lower esophageal sphincter.

8

When does LES return to normal? post partum

48hrs

1-4 weeks for pyloric sphincter tone to return

chestnut p 35

9

what two "things" likely account for the slight decrease in PaO2 and increase in shunting that are observed in asp pneumonitis?

Bronchospasm and disruption of surfactant

10

Mild to moderate headache, lasting 30 minutes to 7 days. Often bilateral, non pulsating, and not aggravated by physical activity

tension h/a

*often circumferential and constricting, can be associated with scalp tenderness, and are usually of mild to mod severity.

11

Recurrent moderate to severe headache, lasting 4 to 72 hours. Often unilateral, pulsating, and aggravated by physical activity. Associated with nausea, photophobia, and phonophobia

Migraine

*rare to manifest for the first time during pp period

12

examples of :
H2 antagonists

PPI:

**matching category of drug**

13

Hypertension and/or HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome Headache
often bilateral, pulsating, and aggravated by physical activity

Preeclampsia/eclampsia

14

Severe and diffuse headache with an acute or gradual onsetPossible focal neurologic deficits and seizures

Posterior reversible (leuko)encephalopathy syndrome (PRES)

15

Ischemic or hemorrhagic.Cerebral infarction/ischemia: new headache that is overshadowed by focal signs and/or disorders of consciousness.Subarachnoid hemorrhage: abrupt onset of an intense and incapacitating headache.Often unilateral accompanied by nausea, nuchal rigidity, and altered consciousness.

stroke

16

Headache usually without typical features Often overshadowed by focal neurologic signs and/or altered consciousness

Subdural hematoma

17

Late developing headache that is constant in nature Bilateral or unilateral location

Carotid artery dissection

18

Nonspecific headache that may have a postural component.Often accompanied by focal neurologic signs and seizures

Cerebral venous and sinus thrombosis

19

Progressive and often localized headacheOften worse in the morningAggravated by coughing/straining

brain tumor

20

Progressive non pulsating headacheAggravated by coughing/strainingAssociated with increased CSF pressure and normal CSF chemistry

Idiopathic intracranial hypertension (pseudotumor cerebri/benign intracranial hypertension)

21

No history of dural trauma Diffuse, dull headache worsening within 15 minutes of sitting or standing Associated with neck stiffness, nausea, tinnitus, and photophobiaCSF opening pressure < 60 mm H2O in the sitting position

Spontaneous intracranial hypotension

22

Frontal headacheOften an abrupt onset immediately after dural punctureSymptoms can worsen with upright posture

Pneumocephalus

23

Headache is most frequent symptomOften diffuseIntensity increases with timeAssociated with nausea, photophobia, phonophobia, general malaise, and fever

menigitis

24

Frontal headache with accompanying facial painDevelopment of headache coincides with nasal obstructionPurulent nasal discharge, anosmia, and fever

Sinusitis

25

Onset of headache within 24 hours of cessation of regular caffeine consumptionOften bilateral and pulsatingRelieved within 1 hour of ingestion of caffeine 100 mg

Caffeine withdrawal

26

Mild to moderate headache associated temporally with onset of breast-feeding or with breast engorgement

Lactation headache

27

the classic presentation of subarachnoid hemorrahage:

"worst headache of my life"

sudden onset of a severe h/a that is unlike any previous h/a

28

Mild to moderate headache associated with ondansetron intake

Ondansetron headache
