Q

So neurologic origins of pain during labor and childbirth there are three types of pain experienced by women during the first stage of Labor
Visceral pain:
Referred pain:
Somatic pain:

Q

from cervical changes, distention of lower uterine segment, and uterine ischemia (First and third stages of labor)
contractions cause cervical dilation and effacement
uterine ischemia results from compression of the arteries supplying the myometrium during uterine contractions the pain from distention of the lower uterine segment stretching of cervical tissue as it efaces and dilates pressure and traction on adjacent nerves and structures and uterine ischemia during the first stage of Labor is visceral pain

A

Q

originates in uterus, radiates to abdominal wall, lumbosacral area of back, iliac crests, gluteal area, and down thighs
Is located over the lower portion of the abdomen
originates when the pain that originates in the uterus radiates and that’s what referred pain is it
doesn’t women who or anybody really who’s actually had their abdomen opened up during surgery and closed and stitched back up people will complain of severe shoulder pain after an abdominal surgery there’s nothing wrong with her shoulder they have trapped air that is causing referred pain to the shoulders so that’s what referred pain is a woman in labor will have referred pain during most of the first stage of Labor the woman usually has discomfort only during contractions and is free from pain between the contractions during the second stage of Labor the woman has so much pain which is often described as intense sharp burning and very well localized as you can see down here and be well actually no skip down to see there’s seat this pain results from the following distention and traction on the peritoneum and uteruservical supports during contraction pressure against the bladder and rectum stretching and distention of the perineal tissues and laceration of the soft tissues of the cervix vagina and perineum so most of this pain they said they stop they feel the contractions but what they’re complaining of most is right here this red area

Q

pain described as intense, sharp, burning, and localized
Stretching and distention of perineal tissues and pelvic floor to allow passage of fetus from distention and traction on peritoneum and uterocervical supports during contractions and lacerations of soft tissue
Second stage
Is right here this red area which would make sense they’re about to give birth to a baby pain experience or the third stage of Labor or when the placenta is delivered and the after Pains of that early postpartum period or uterine similar to the pain experienced early in the first stage of Labor so that would be more visceral pain

Q

can affect the intensity of childbirth pain and we know pain is tough because it is very subjective you’ll see one woman react one way and another woman react to completely different way in the same phase of Labor fatigue can decrease or if she just worked at 12 hour shift at night and then gets home and then her labor starts she’s already tired it’s going to be harder for her to cope

Q

anxiety is commonly associated with increased pain during labor mild anxiety is considered normal for a woman excessive anxiety and fear however cause more catecholamines secretion which will increase stimuli to the brain and increase that pain perception this is anxiety and fear heightened muscle tension increases in the effectiveness of uterine contractions decrease we often call this the bear tension pain cycle as the fear elevates detention the body tightening up and using a lot of energy will increase which will make you sore and worn out and will increase the pain which will also increase the anxiety which will increase the tension so if I can never ending cycle challenge

Q

Childbirth for a healthy young woman maybe her first experience was significant pain and as a result she may not have developed effective pain coping strategies this is what we talk about when we’re referring to previous experience women who’ve had three and four kids know exactly what to expect their neighbors are shorter typically is each with each child and they know what to expect so they’re a little less afraid of the painful experiencing experiences in her life may have a really hard time coping if she’s not prepared adequately

Q

helps explain the way hypnosis and the pain relief techniques taught in childbirth preparation classes work to relieve the pain of Labor according to this Theory pain Sensations travel along sensory nerve Pathways to the brain but only a limited number of Sensations or messages can travel through these nerve pathways so using distraction techniques you can they work by closing down a hypothetic gate in the spinal cord that’s preventing the pain signal from reaching the brain and the perception of pain is there by diminished so obstetric pain management techniques that utilize distraction include massage a back massage or effleurage of the abdomen aromatherapy hypnosis music guided imagery there’s there’s quite a few different ways that we can distract the pain signal from reaching the brain and thus decrease the perception the main impetus behind the gate control theory as it relates to pain to a positive stimulus by using all of the five senses to accept the more positive stimulus and pay less attention to the negative

Q

Comfort the most helpful interventions enhancing Comfort are caring nursing approach in a supportive presence which leads you to support evidence indicates that a woman satisfaction with her labor and birth experience is determined by how well her personal expectations of childbirth and the quality of support and interaction she receives from her caregivers women who have continuous support beginning early and labor or less likely to use pain medications or epidural analgesia or anesthesia and are more likely to experience a spontaneous vaginal birth and express satisfaction with their childbirth experience

important because if they’re very stressed out if there’s a lot of lighting if there’s a lot of people in the room it’s a lot of noise in the room that’s what you may think is being more of a distraction technique actually has the opposite effect where it’s more like a living room environment or a home environment or have home births because it’s the most comfortable place that you know to help with that nonpharm management

Q

many non-pharmacologic measures is comparable to or even Superior to that of opioids that are administered parentally
In the past few years attendance a child with education classes has declined increasing numbers of women are utilizing online childbirth education rather than attending traditional classes
Encourage nonpharm first - need know how cope with pain
Nonpharmacologic measures often simple, safe, few adverse reactions, and inexpensive
Provide sense of control over childbirth
Methods require practice for best results
Try variety of methods and seek alternatives, including pharmacologic methods, if measure used is not effective

Q

choose them first before going to pharmacologic measures many of the non-pharmacologic methods for relief of discomfort are taught in different types of prenatal preparation classes or the women or couple may have searched the internet or reads various books and articles on the subjects in advance
however any of these methods require practice for best results because of the increased use of epidural analgesia or anesthesia nurses may be less likely to encourage women to use non-pharmacologic measures in part because these methods may be viewed as more complex and time consuming
Lamaze, Bradley, breathing techniques, touch, hydrotherapy, hypnosis, music
Lamaze and Bradley are several childbirth prepared methods women can take classes with their Partners however in the past few years attendance
some other techniques would be distraction techniques to attention focusing techniques like breathing paste breathing imagery Pace breathing
effleurage which is that light stroking usually of the woman’s abdomen counter pressure so back lower back pain is very effectively comforted with some steady pressure applied to Mom’s hips Touch Massage the feet the the shoulders the back application of heat or cold acupressure some countries use something called a transcutaneous electrical nerves stimulation or TENS unit during labor and especially in the postpartum
increase in aromatherapy though especially with the invention of Doterra and Young Living
hypnosis

Q

should be implemented before pain becomes so severe that catecholamines increase and labor is prolonged
it is unacceptable for women in labor to endure severe pain when safe and effective relief measures are available unless she wants to be in that pain but then even then we need to attempt the non pharmacologic pain management
pharmacologic and non-pharmacologic measures when used together increase the level of pain relief and create a more positive labor experience for the woman and her family
Sedatives
Analgesia and Anesthesia

A

Pharmacologic pain management

17
Q

sedatives relieve anxiety and induce sleep they may also be given to augment analgesics and reduce nausea when an opioid is being used don’t typically use them very metally Phenergan not using those very very much anymore but they can be used together so you’ve got Valium Ativan Phenergan seek and all just to help Mom relax not necessarily to take all the pain away however because of the potential for neonatal central nervous system depression barbiturate should be avoided if birth is anticipated within 12 to 24 hours so anything that’s going to barbiturates as in the secanal I’ve not seen seeking all used very much at all it’s been a long time since I’ve seen that used anything that’s going to pass the blood-brain barrier of the fetus is going to impact how they respond to the extra uterine environment

A

Sedatives

18
Q

so keep this in mind as we go through this analgesia and anesthesia anesthesia encompasses analgesia Amnesia relaxation and reflex activity anesthesia abolishes pain perception by interrupting the nerve impulses to the brain the loss of sensation
Refers to the alleviation of the sensation of pain or the raising of a threshold for pain perception without loss of consciousness so here are some systemic analgesia
Opioids
Opioid Agonist
Opioid Agonist-Antagonist
Opioid Antagonists

A

Analgesia and Anesthesia

19
Q

provide sedation and Euphoria but they’re analgesic effect in labor is fairly Limited we often go straight for the short acting analges because of because they actually readily cross that placenta effects on the fetus and newborn can be profound including absent or minimal fetal heart rate variability which we’ll talk about in the next chapter and significant neonatal respiratory depression requiring treatment right after birth the opioid the opioids commonly used currently In Obstetrics are my parading fentanyl Fentanyl and now beeping which is new Bang a parenting Fentanyl

A

Opioids

20
Q

Fentanyl are opioid agonists because opioids can inhibit uterine contractions they should not be administered until Labor as well established unless they are being used to enhance therapeutic rest during prolonged early phase if you remember from lecture early phase is the longest of the three phases of the first stage of Labor in fact it’s not it’s as long as both second and third are as long as active in transition put together it’s the longest now some women have a prolonged early phase labor giving them a little bit of an opioid Agonist or even an opioid with a sedative however neonatal effects can persist for the first two to three days of life with my parity so my parenting which is your Demerol we don’t typically use because of that effect but you can

A

Opioid Agonist

21
Q

opioid Agonist antagonist analgesic would be your newbane it’s commonly used in the labor and delivery setting the opioid Agonist antagonists are Agonist at the Kappa opioid receptors you don’t need to know all the ins and outs of these this is not pharmacology so you don’t need to worry about the method of action the onset and the peak I’m not asking for any of that okay what I want you to take away from these systemic and analgia or anesthesia is that it does cross the placenta it does affect the fetus this is very important opioids can also cause excessive CNS depression in the mother or both of them

A

Opioid Agonist-Antagonist

22
Q

we also have Narcan on hand for Mom and for baby so if the excessive CNS depression in the mom we give Mama some Narcan if baby is born we give a that’s why they’re short acting again and we give Mom an injection of State all or newbain or fentanyl and the baby is born soon after that Administration the baby is still experiencing effects so they don’t want to breathe it’s the first time taking a big deep breath and they’re going to not want to do that so we always make sure that we pass on to the nursery nurse the last time that that system that they can be prepared in case they need to administer the Narcan to the newborn let’s see here what else can we tell you about this so yeah as far as like your medication guide on pages like 346 and 347 you don’t need to worry about all those details I’m not going to ask you what the dosages for newbane for the first time you have Minister not important just understand the big picture idea systemic it’s going to affect the baby and what happens when the baby is seeing us depressed they don’t want to breathe they don’t want to suck they don’t want to do anything but be a blob so we have to reverse him sometimes with Narcan

A

Opioid Antagonists

23
Q

Several different methods referred to as neuraxial analgesic and anesthetic techniques are used and obstetrics to produce sensory blockade in various degrees of motor blockade over a specific region of the body a variety of local anesthetic agents are used in these techniques to reduce Regional anesthesia the principal pharmacologic effect of local anesthetics is the temporary Interruption of the conduction of nerve impulses notably pain these are usually your cane drugs that were using to produce the sensation
Leaving the discomfortable labor and vaginal birth a block from the 10 to S5 is required for cesarean birth of block from T8 to S1 is essential so same way with a spinal we got to get her to curve her back and assume the Sims position or sit on the edge and really really roll her shoulders over to open up that integral space to allow for them to put the needle in insert the epidural catheter they take the needle out they tape up the epidural catheter in the right space and that is a joint effort the nurse and the CRNA or anesthesia provider where she’s checking mom’s pulse she’s got a pulse oxide and then make sure there’s not a significant increase in Mom’s heart rate and Mom doesn’t experience side effects of having that lidocaine opioid are there legs automatically fall asleep the CRNA will kind of go over what to expect during that initiation the testos was good to go they go ahead and hook her up to the pump and get her get her comfortable woman is positioned preferably on her side but not completely on our sides this is kind of done with the wedge we want to get the uterus off of that ascending being a Cava and the descending a order and we’re taking blood pressures about every 3 minutes to assess for hypotension I didn’t need to make sure oxygen is on standby and ephedrine which will be given by the CRNA and if need be you open up your IV fluids to give her a little bolus beat a heart rate pattern and contraction pattern is all also evaluated closely if Mom has a drop in her heart rate baby will have a reflexive reaction to that as well with a drop in their heart rate the most common message of epidural block is the continuous block so it’s hooked to a pump they’re not coming in and giving additional additional injections so the advantages of epidural blocker there’s quite there’s quite a few they’re awake they’re comfortable they good relaxation Airway reflexes remain intact but the disadvantages are fairly numerous the women’s ability to move freely into maintain control of her labor is limited she’s not getting out of the bed CNS effects can occur if a solution containing a local anesthetic agent is accidentally injected that’s why we do that testos hypotension hypotension happens this is 10 to 30% of women I’m betting it’s higher anecdotally would be higher hypertension you typically are going to see at some degree I can result in significant decrease in utero placental perfusion and auction delivery to the fetus urinary retention so we got to put a Foley in and they’ll tend to itch women who what’s making them itch is the fentanyl it’s not a reaction it’s not it’s just a side effect of the fentanyl they’ll be a little itchy so that’s our epidural so some contraindications people who can’t get a spinal or epidural these would be somebody who has an active maternal hemorrhage maternal hypertension we’re having a hard time maintaining her blood pressure coagulopathy so if a woman’s receiving anticoagulant therapy she has to have been off of it for over 12 hours if she’s a bleeding disorder and that’s just because we don’t want to introduce that needle into her back and bleed into her spine she has an increased ICP due to mass if she’s allergic to any of it if she refuses or is it able to cooperate and then there are some maternal cardiac conditions were that she she can not have an epidural or spinal
Local perineal infiltration anesthesia
Pudendal nerve block
Spinal anesthesia (block)
Epidural anesthesia/analgesia

A

Pharmacologic pain management: nerve blocks

24
Q

that would be just a local block right there on the perineum either before the head is delivered or after or in that fourth fourth stage of Labor when we’re doing the episiotomy repair lacerations that need to be sutured to do a repair nerve block does not relieve the pain from the contraction it does absolutely relieve the pain in the lower vagina the vulva and the perineum

A

Local perineal infiltration anesthesia

25
Q

that would be just a local block right there on the perineum either before the head is delivered or after or in that fourth fourth stage of Labor when we’re doing the episiotomy repair lacerations that need to be sutured to do a repair nerve block does not relieve the pain from the contraction it does absolutely relieve the pain in the lower vagina the vulva and the perineum
our spinal block to the lowest final anesthesia may be used for vaginal birth but it is not suitable for labor
most women in labor are going to get the epidural block
typically is used for a scheduled C-section - Mama cannot feel anything we call it from the tits to the toes
how this is place is a woman sits or lies on her side with a back curve to whiten that intervertebral space after the anesthetic solution is injected the woman may be positioned up right to allow the anesthetic solution to flow downward to obtain a lower level in a seizure for vaginal birth to obtain the higher level she’ll be positioned to Pine with the shoulders and the head slightly elevated going to displace the uterus of course and the spinal will actually last for one to two hours so it’s fairly ideal for a C-section because well they’ll place it layer back and get her draped and and or get her prepped for surgery and surgeries don’t usually take that long so the anesthetic effect will start to wear off
before the induction of this anesthetic maternal vital signs are assessed in a 20 to 30 minute electronic fetal monitor strip is obtained mother is bolused with LR 15 to 30 minutes prior to the induction of the anesthetic to help ward off that hypotension fluid
there’s a higher incidence of bladder and uterine attack as well as postural puncture headache or that spinal headache we call it leakage of the CSF from the site of the puncture is the major cause and so that’s called the spinal headache and how we fix that yeah we’ll try caffeine drip or blood patch will actually draw blood for Mom’s arm and the CRNA will inject her blood into her into her back to help a clot off
we know a woman has got a spinal headache is when she complains of severe headache as soon as she sits up and then when she lays flat there’s no headache that is the Hallmark of a spinal headache
Disadvantages

Spinal anesthesia (block)

26
Q

Marked hypotension
Impaired placental perfusion
Ineffective breathing patterns

Autologous epidural blood patch

A

Disadvantages - Spinal anesthesia (block)

27
Q

achieved by injecting a suitable local anesthetic agent
From T10 to S5 is required for cesarean birth of block from T8 to S1 is essential so same way with a spinal we got to get her to curve her back and assume the Sims position or sit on the edge and really really roll her shoulders over to open up that integral space to allow for them to put the needle in insert the epidural catheter they take the needle out they tape up the epidural catheter in the right space and that is a joint effort the nurse and the CRNA or anesthesia provider where she’s checking mom’s pulse
she’s got a pulse oxide and then make sure there’s not a significant increase in Mom’s heart rate and Mom doesn’t experience side effects of having that lidocaine opioid
legs automatically fall asleep the CRNA will kind of go over what to expect during that initiation the
positioned preferably on her side but not completely
wedge we want to get the uterus off of that ascending vena Cava and the descending aorta and we’re taking blood pressures about every 3 minutes to assess for hypotension
it’s hooked to a pump they’re not coming in and giving additional additional injections so the advantages of epidural blocker there’s quite a few they’re awake they’re comfortable they good relaxation Airway reflexes remain intact but the disadvantages are fairly numerous the women’s ability to move freely into maintain control of her labor is limited she’s not getting out of the bed CNS effects can occur if a solution containing a local anesthetic agent is accidentally injected that’s why we do that testos hypotension significant decrease in utero placental perfusion and delivery to the fetus urinary retention so we got to put a Foley in
they’ll be a little itchy
Positioning
Difficulty if patient is obese
Disadvantages/contraindications

A

Epidural anesthesia/analgesia

28
Q

contraindications people who can’t get a spinal or epidural these would be somebody who has an active maternal hemorrhage maternal hypertension we’re having a hard time maintaining her blood pressure coagulopathy increased ICP if she’s allergic to any of it if she refuses or is it able to cooperate and then there are some maternal cardiac conditions

Disadvantages/contraindications - Epidural anesthesia/analgesia

A

Pain management: other

30
Q

Used rarely for vaginal births
Infrequently for elective cesarean section
May be necessary if indications necessitate a rapid birth
rarely used for uncomplicated vaginal birth like I have never seen a general anesthetic used for a vaginal birth and it’s used for about 10% of cesareans general anesthesia may be necessary if a spinal epidural block is contraindicated or if circumstances necessitate a rapid birth
major risk associated with general anesthesia are difficulty with or inability to intubate and aspiration of gastric contents if general anesthesia is being considered an IV infusion yet Npo need to be pre-medicated with usually an oral antacid and an H2 receptor blocker like Pepcid or Zantac and then Reglan so they’re got a preload them with some medications
with a wedge add to displace the uterus we’re going to pre-oxygenate with 100% O2 and then they’re going to start giving her medications
in the event that you’re asked to assist with applying cricoid pressure
priorities for post anesthesia care are to maintain an open Airway and cardiopulmonary function and to prevent postpartum Hemorrhage we don’t like doing general anesthetic because it absolutely affects the fetus

A

General

31
Q

Used extensively in other countries
Getting popularity in the United States as an alternative
Self-administered
Laughing Gas
it’s administered in a 50/50 mix with oxygen and a blender mask
does not completely relieve the pain but reduces the perception it causes that euphoric feeling and decreases their anxiety the main side effects of nitrous oxide are nausea and dizziness it is safe for both mother and fetus and does not affect you during activity other advantages include rapid asset of action quick clearance through exhalation without accumulation and maternal or fetal tissues so but those mamas that are a little bit more anxious than the rest this would be a fabulous fabulous method for their anxiety and their pain management especially early in labor

33
Q

first thing is pain assessment Pain Scale usually the 0 to 10 Pain Scale is often used to evaluate women’s pain before and after pain relief interventions are implemented so we do a lot of pain assessment and labor and delivery assess provide the intervention reassess the timing of when you reassess depends on the route in which you gave it this is all fundamental nursing stuff that you learn two semesters ago so pain assessment

A

Pain Assessment

34
Q

non-pharmacologic interventions the nurse supports an assist the women a woman as she uses non pharmacologic interventions for pain relief and relaxation during labor the nurse evaluates the effectiveness appropriate interventions can then be planned or continued for Effective care so for non pharmacologic interventions if she’s using imagery guided imagery and music and aromatherapy shooting all of that and she’s still struggling you’re assessing how well she’s coping with that non-pharmacologic pain documenting it in the record and perhaps offer her something different you know what maybe let’s get up let’s stand up and you guys slow dance beside the bed do something different if she’s having a hard time coping with what she’s doing currently you need to change it up to find something that might help her better

Your Role is to clarify describe procedures or act as the woman’s advocate and act the primary health care provider for further explanation

A

Informed Consent

37
Q

IV route the preferred route would be for things like the - it’s important to give these opioids during a contraction maybe give an over period because that uterine blood the uterine blood vessels are constricted during contractions and the medication stays within the maternal vascular system for several seconds before the uterine blood vessels reopen so you know you can’t just go in there and push it you have to maybe stand there for about 5 or 10 minutes
IM is not preferred because it’s painful however the advantages of using IM route are quick Administration and there’s no need to start an IV line however the disadvantages would be the onset of pain relief is going to be a bit delayed and you need higher doses of the medication
for regional the non anesthetic registered nurse so that would be you the bedside nurse is permitted to do the following when it comes to the epidural or spinal monitor the status of the woman and fetus replaced the empty infusion syringes her bags you can stop the infusion you can remove the catheter if you’re properly educated to do so and you have to initiate emergency measures as needed communicate clinical assessments and changes in patient status to the obstetric in anesthesia care providers
all bedside nurse can do is change it if it’s empty they can put a new syringe in and start it back they can take a catheter out and they assess assess assess so the spinal nerve blocks and epidurals are going to decrease bladder sensation
So the spinal nerve blocks and epidurals are going to decrease bladder sensation so women are going to have to have a fully catheter and of course then once you turn off the pump so if she’s got continuous epidural going and she’s delivered her baby you have to stop the pump otherwise she’s not ever going to be able to get hurt - important for them to regain some control bladder control

A

Administration

38
Q

the nurse monitors and Records the woman’s response to non-pharmacologic pain relief methods and medications continues to monitor maternal Vital Signs and fetal heart rate and pattern
frequent intervals monitor uterine contractions the change in the cervix determining the fetal response after administration of analgesia or anesthesia we have a lot going on when it comes to nursing interventions
know that we’re doing a lot more vital signs a lot more assessment and you know because Mom can’t move when she’s got an epidural it’s important that you continue to position her to help baby find encourage or assist the woman to change positions from side to side every hour or so you’re you’re in there getting her moved around so that the baby finds the best fits that we don’t prolong her labor
