A
  • Childbirth is a “normal” process
  • Has months to prepare for labor

Q

pain during labor and birth

A

-Neurologic origins
-Perception of pain
-Expression of pain
-Factors that influence pain response (tolerating pain - how much pain someone is willing to induce; support? prepared? what methods individual wants)
peoples response in labor - blood pressure increase, n/v, can hyperventilate which increases pain level

Q

Physiologic Factors

A

dilation and effacement (thinning of cervix) - allow baby to leave uterus
pressure and pulling on pelvic structures
distention of the vagina and perineum
contractions - stop blood flow
fatigue - the more tired you are the less you can handle pain
support and help of caregivers
fetal position - face presentation can cause more pain

Q

other factors

A
  • culture
  • anxiety - if pt is nervous and they don’t know whats going to happen, muscles will tense
  • pervious experience - will affect ability to cope
  • gate-control theory of pain - paplov’s, distract brain will decrease pain level
  • comfort - position mom wants to be in will diminish pain
  • support
  • environment - comfortable? can see more around?

A

no side effects to the fetus, risk for sedation decreases, don’t slow down labor

A

if doesn’t work then between a rock and hard place if only method for pain, have to be educated before labor

Q

Criteria for pain relief

A
  1. must be as safe as possible for mom/baby
  2. must relieve pain
  3. must not interfere with labor progress

16
Q

pharmacologic pain relief

A
  • if drug passes placenta will have some effect on baby
  • epidural can compromise mom bp and then endanger fetus blood flow
  • no pain relief until active stage of labor, if given too early then can stop labor
  • some meds might not be okay depeds on mom and baby
17
Q

opioid agonists drugs

A

Dilaudid (takes effect 10-15 min), Demerol (IV push, given over morphine but high rate of respiratory depression), Fentanyl (Sublimaze) (short acting), Sufenta

18
Q

opioid agonists

A

reduces proceptions of pain w/o sedation, higher level of people vomiting, given IV some IM, usually if birth in 4 hours don’t give IV meds, watch respiratory rate in mom

19
Q

opioid (narcotic) agonist

A

stadol, nubain – act to depress pain at certain receptor sites

20
Q

opioid (narcotic) antagonists

A

narcan - give to newborn after delivery or to mom in labor

21
Q

nerve block analgesia and anesthesia

A
  • Local Perineal Infiltration
  • Pudendal Block
  • Epidurals
  • Spinal (subarchnoid block)
  • Combined Epidural/Intrathecal(spinal)
  • General anesthesia/Nitrous Oxide (malpractice in the US, have to get baby out in 5 minutes)
22
Q

local perineal infiltration

A
  • Usually xylocain 1%
  • Numbs perineum for repair of episiotomy
  • No relief of contraction pain
  • Fan like multiple injections
  • Post delivery: ice to perineum (24hrs.) to decrease edema, hematoma formation then sitz baths

not to give relief from pushing or contractions, done for repair of epistotomy

23
Q

pudendal block

A
  • Numbs the lower vagina/perineum for vaginal birth
  • No relief of contraction pain, done just before delivery for vacuum and forceps delivery
  • Transvaginally inject the pudendal nerve through the vagina using a trumpet needle guide
  • Usually xylocaine 1%
  • not for relief of contraction for 2nd pushing stage
24
Q

Epidural

A
  • Pain relief for both contractions and delivery
  • Type of regional anesthesia
  • Usually a local anesthetic and an opioid analgesic are used together
  • Injected into epidural space between the dura and the spinal canal,usally L3-L4 for vaginals and T4-T6 c-sections. Can reposition for c-sec. if it’s not expected
  • most common in US
  • epidural space- negative pressure space
  • want mom laying straight or have hot spots where it goes to the side
  • does not get rid of al sensations of done correctly
  • have to have time for it to take affect
  • watch for oxygenation so mom has pulse ox
25
pior to epidural
``` “cat” position prep w/ Betadine skin wheal to numb injection area uses glass syringe with 18# needle -has to be dead center in the epidural space to balance it ```
26
epidural requires
10x more med than spinal because it is outside the meninges - Sooo…Give a test dose BEFORE starting large amounts of medication - Test dose: to watch for improper placement in a vein or in the subarachnoid space - Epinephrine (3 ml) is given before a full dose is given
27
With intravascular injection you have
tachycardia, Pulse O2 <95% , C/O Ringing in ears/tongue numbness THEN lightheadness THEN twitching THEN coma THEN seizures
28
With insertion into spinal fluid
rapid & intense motor and sensory block
29
last steps of epidural
Then combination of drugs are given– Local anesthetic (Naropin) with an analgesic (Fentanyl) All drugs are preservative free to prevent paralysis by drug attaching to nerve root and sloughing off Takes approximately 20 minutes to take affect and is positional - needs to be preservative free so no damage to the nares
30
Adverse effects with epidural
``` Hypotension Bladder distension Prolonged 2nd stage Catheter migration Nausea and vomiting Pruritus Delayed respiratory depression itching something ordered PRN ```
31
Nursing care for epidurals
``` Preload with RL 500-1000ml Displace uterus to left manually with a wedge Assess for hypotension Assess FHR Evaluate bladder regularly and empty PRN Transfer and move with assistance Up only after epidural has worn off ```
32
(spinal) subarchnoid block
Done when a stat c-section is needed and no epidural has been done Major problems: hypotension, headaches, bladder distension Advantages: simple, rapid, low failure rate
33
spinal care
Bed rest Hydration May need a blood patch- 10-15 mls of the woman’s blood is injected into the epidural space to close dura and stop spinal fluid leakage CAN DO A EPIDURAL/SPINAL COMBINATION
34
general anesthesia
For c-section-- if epidural or spinal not possible or if woman refuses a regional Leading cause of death is aspiration Considered malpractice by many if used for a vaginal delivery Meds do cross the placental barrier and end up w/ sleepy infants at delivery To reduce amount of time with anesthesia till cord clamping, woman is prepped and draped before anesthesia is given contraindicated unless mother won't let you do anything else or emergency
35
general anesthesia nursing implications
Check on last time food/fluid Restrict fluid intake PO Give ordered drugs (IV Pepcid) - prevent aspirating Give O2 after extubation and evaluate O2 saturation after procedure (>95%)
36
general anesthesia steps
First, gives Penathol and O2- no pain relief but puts to sleep for intubation Wedge under hip SELLICK MANEUVER Second, Nitrous Oxide and O2 till cord is clamped—procedure is timed to get baby out within 5 minutes Third-After cord clamped meds to produce deep sleep-more Penathol, narcotics and inhalation agents
37
posible complications post delivery
Fetal depression Uterine relaxation Vomiting and Aspiration
