31

Perineum

S2,S3,S4

Pain impulses carried by somatic nerve fiber; pudendal nerves

32

Inhalation agents
effects on uterus

Cause uterine relaxation - increase blood loss

33

Parentral agents effects on labor

Opioids minimally decrease progression of labor

34

Regional anesthesia is given for:

Primigravida
Prolong labor
High parenteral analgesic requirement
Use of oxytocin
Large baby
Small pelvis
Fetal malpresentation

35

Vasopressors
a1 stimulation effects

uterine contraction

36

Vasopressors
b2 stimulating effects

uterine relaxation

37

Small dose on phenylephrine effects

increase blood flow increase bp

38

Oxytocin uses

Used to induce labor and to prevent postpartum blood hemorrhage

39

oxytocin complications:

Complication: fetal distress, uterine tetany, maternal water retention, hypotension, reflex tachycardia

40

Ergot alkaloids
uses

to treat uterine atony

41

What is used to treat PPH?

Prostaglandins

42

Magnesium
uses

Use to stop premature contraction and to prevent eclamptic seizures

43

magnesium side effects

Side effects: hypotension, heart block, muscle weakness and sedation. Also INCREASES blockage of non-depolarizing agents. Cardiac and respiratory arrest can occur

44

treatment for magnesium side effects

Treatment
D/C- mag
Calcium
Lasix

45

B2 agonist

stop premature labor

46

Hypotension

Ephedrine, oxygen, left uterine displacement and IV fluids. Small doses of phenylephrine can also be used

47

Unintentional IV injection (of epidural)

Place supine with left uterine displacement
Thiopental or propofol to stop seizures

48

Unintentional intrathecal injection

Place supine with left uterine displacement
Ephedrine and fluids
Intubation and ventilation in high spinal

49

Postdural puncture headache

Bed rest
Hydration
Oral analgesic
Caffeine

50

Postdural puncture headache

blood patch

51

Signs of Fetal Distress (7)

Repetitive late deceleration
Loss of beat-to-beat variability
Fetal heart rate < 80
Fetal scalp pH < 7.20
Meconium stained amniotic fluid
Oligohydramnios
Intrauterine growth retardation

52

Obesity what % of ideal body weight
BMI
morbid obesity BMI

>20% of ideal body weight
BMI >30
BMI>40

53

obesity labs

High glucose, cholesterol and TG

54

obesity PFT results

restrictive lung disease

55

obesity breathing issues

increase work of breathing
decrease ERV (expiratory reserve volume)
decrease FRC
decrease chest wall compliance

56

in morbid obesity- closing capacity results in

In morbid obesity, closing capacity exceeds FRC - V/Q mismatch - arterial hypoxemia

57

obesity distribution of lipid soluble drugs

Increase volume of distribution for lipid-soluble drugs

58

treatment for pickwickian syndrome

Oropharyngeal appliances
Positive pressure nasal mask
Surgery

59

Obesity-hypoventilation syndrome leading to (ten things total listed)

Hypercapnia
Hypoxemia
Somnolence; poor sleep at night
Pulmonary HTN
Systemic HTN
RVH / LVH
Dependent edema
Cyanosis-induced polycythemia
Rales
Pulmonary edema
