Vag and C-section PPT McDizzle's lecture Flashcards
Something to consider epidural analgesia is PAIN control, epidural is blocks LA
ACOG
American Congress of Obstetricians & Gynecologist
on 1993 the ACOG committee on pain relief during labor number 118 stated what?
“…. maternal request is sufficient justification for pain releif during labor….”
ASA
American Society of Anesthesiologist (aka Anesthesiologist are a Sublevel of Anesthetists)
Ingards to Mcd’s research on intrathechal and eidural analgesia he found out what?
that the length of labor was NOT prolonged using intrathechal or epidural opiods, and may shorten the 1st stage of labor in both primi and multiparious women.
Regional anesthesia for child bearing is philosophy both _____ and _____
- Safe
- Participatory (providing the opportunity for individual participation )
What occurs in the 1st stage of labor (5 main body changes)
- Pressure on nerve endings of the uterus
-Contraction of an ischemic myometrium and cervix
-Vasoconstriction
-inflammatory changes
-Dilation of the cervix and lower uterine segment
( how to remember– 1st
the PRESSURE on the nerve ending of the uterus cause VASOCONSTRICTION, which causes the contraction of an ISCHEMIC MYOMETRIUM AND CERVIX, which causes INFLAMMATORY CHANGES, and thus DILATION of the cervix and lower uterine segment)
I dunno maybe it will help???
What causes the 1st stage perceptions?
result of dilation, distention, and stretching of the cervix and lower uterine segment during contraction.
What Causes perception during the 2nd and 3rd stages of labor?
-Traction on the pelvic peritoneum and uterine ligaments
-Tension on the bladder and rectum
-tension on the ligamnets, fascia and muscles of the pelvis
-Pressue on lumbrosacral plexus
(how to remember- stage 2 and 3 the baby is moving down so the pain is lower and it STRETCHES everything by pulling it down)
Somatic pain in the 2nd stage of labor via vaginal and perineal in orgin are from what nerves
pudendal nerves S2-4
What dermatomes cover the perineum
S2-S4
what ligaments are stretched or placed under tension in stage 2 and 3 of labor
- Round ligaments
- Superior pubic ligaments
- Broad ligament
- Cardinal ligament
What factors can influance the perception of Pain r/t labor
- pain tolerance
- Pain threshold
- Individual factors (Intrapersonal, interpersonal, societal)
- Supportive structures
- Cultural factors
What are the 3 NON-pharmacological pain releif THEORIES for prepared child birth?
Grantly Dick-Reed (childbirth without fear)
Lamaze (Psychoprophylaxis)
Fredrick Le Boyer (Birth without Violence)
explain Grantly Dick-Reed non-pharm pain relief for birth
(Childbirth without Fear)
- Natural childbirth
- Believed that pain was a result of not knowing what is happening during labor and delivery
Explain Lamaze non-pharm pain relief for birth
(Psychoprophylaxis)
-Relaxation and breathing techniques
Explain Fredrick Le Boyer non pharm pain relief for birth
(Birth without Violence)
- gentle approach to birthing using “bath” placing women into a bath to ease the transition from the womb to the real world
What are 4 other non pharm pain releif for labor
Hypnosis
TENS
Acupunture
Alternative birthing options
Advantages of systemic analgesics for labor.
5
Ease of use Staffing no IV required (IM) Minimal monitoring Few complications
Disadvantages of systemic analgesics for labor (5)
effectivness depression respiratory decreases N/V Fetal depresion
Main disadvantage of systemic analgesics for labor
Don’t work very well
Opioids for labor with potency
Demerol 0.1 (1/10) Morphine 1 (of historic interest only) Alfentanil 10-5 Fentanyl 75-125 Sufentanil 500-1000
Opioid agonist/Antagonists for labor pains (with potency if u care)
- Nalbuphine (nubain) 0.7-0.8
- Butorphanol (Stadol) 5
- Pentazozine (Talwin) 30-60 mg = 10mg morphine
********** Why is stadol out of favor for use in some OB settings?
Due to a 75% incidence of transient sinusoidal fetal heart pattern (considered benign)
can cause narcotic withdrawl in narcotic addicts
Sedatives for Vaginal OB labor (3)
Phenothiazines
Benzodiazepines
Butyrophenones
Examples of Phenothiazines for sedatives
Thorazine
phenergan
Examples of Benzodiazapines for sedatives
Versed
Valium
Examples of Butyrophenones for sedatives
Haldol
droperidol
Anticholinergics
Atropine
Scopolamine
Glycopyrrolate
What to remember about robinul (glycopyrrolate)
it does NOTcross the BBB
what are 3 periphreal nerve blocks for L&D
field block
Pudendal nerve block
Paracervical Block
What are complications of the paracervical block do to? and what are the complications?
-Do to large volumes
complications are
- LA toxicity
- Fetal bradycardia
