WK3: Pain in labour and midwifery team practice Flashcards
What is the role of the midwife in managing pain in labour?
- Educate women + family on pain and their optinos
- Normalise labour pains
- ‘It is not somwhting that we need to take away’
- Pain is effective contractions
- painful contracts bring baby on
- Pain can be different in every lanout and baby
- We work with the pain rather than against it to ensure the women copes best
- Western culture has a sway to the removal of pain in labour. I.e. epidural use
Difference between nursing and midwifery is significant when thinking about pain. Nurses try to relieve it
Describe pain in the context of child bearing.
- Complex
- Personal
- Subjective (is what the woman says it is)
- Multifactorial
- Influenced by psychological, biological, economic and sociocultural factors (it is because of these that s it so different for everyone)
- A normal part of the physiological factors
- Healthy pain: gols is not to remove it but to support the women experiencing it
Explain the impact fear (internal influence) has on labour pain and the midwife role in mitigating this.
- Antagonist to oxytocin is cortisol and adrenaline hormones (fear-related)
- Consider environmental factors that reduce these and induce cortisole
- Women have a deep engrained fear of labour and birth= increases the perception of pain.
- Fear, anxiety and loss of control are associated with increased use of pharmacological pain relief and does not help or remove the pre-existing fear/anxiety (can have long term effects)
Midwives role: to reduce women’s fear and anxiety and communicate in the way that women believe in their abilities (promote courage)
Explain the gate pain theory.
What they propose:
Any nerve signal can go to one of two places to go to the brain. Either inhibitory interneurons or transmission cells.
*nocioceptors detect pain
* mechano receptors detect touch, pressure …
- Mechanoreceptors when stimulated increase inhibitory interneuron on the pain signals
= close the gate to your brain preventing the reception of pain.
Any nerve signals can go to one of two destinations while on the way to the brain. Either the;
Transmission cells= pick of the signal and take it to the brain
Inhibitory interneurons= that it would pass through the first and have the activity less intense.
- Theory based on the existence of a ‘gate’ that could facilitate/inhibit transmission of pain signals
- Brain exerts ‘downward’ control over our experience of pain by influencing the amount of pain stimulation allowed to pass a ‘gate’ in spinal cord
- i.e we experience greater levels of pain if more stimuli is let through the gate
Degree of pain experienced depends on amount of information that gets through the gate to the brain influenced by:
1. Where the pain starts (in peripheral pain fibres)
2. Activity in other peripheral fibres (i.e. carrying competing information)
3. Messages coming from brain (distractions)
What are some non pharmacological pain relief options that ‘close the gate’ and what are their potential benefits and hrams?
rubbing painful site
acupuncture
Hot water
Ice packs
TENS machine
Comb (touch receptor in hand becomes focus point of comb, rhythmic to keep doing, some acupressure points in the hand)
Repeatedly count down from 10
Bounce on a ball for repetition
Benefits: they increase inhibitory interneurons on the pain pathway, thus loading the pain pathway and decreasing the perceived pain (a double negative).
Exercise, distractions and stress can release the body’s own painkillers
E.g. endogenous opiates such as endorphins
What factors impact a woman’s pain perception?
- Consider what triggers the gate to shut?
(action of the synapse at the dorsal horn before the pain signals travel to the brain) - Past experience
- Meaning of situation
- Attention to the pain (focous else where/distraction or attention else where)
- Anxiety (cortisole, stress)
- Anticipation
- Culture
- Expectations
- Suggestion (support person/midwife suggests that the pain is good and normal)
What factors affect the perception of pain?
- Birthing environment (home vs hospital)
- Trust in womans innate ability to give birth
- Level of invasive procedures occurred
- Level of invasive procedures
- Type and length of labour (precip vs long labout)
- Fatigue
- Ability to express pain without judgement
- Feelings of control (not so much in controlling labour, but being in control fo what is done)= indice feelings of safety
How can a midwife assist a woman when choosing pain management
Based on;
- Every women is very individual
- Philosophical approach to birth (is she interested in intervention free? Does she understand why she wants this?)
- What is her attitude to pain (accepting or traumatised)
- Experience withp pain management in the past
- Individual prejudice
- Influenced by close others, especially partner
- offer her all options and give the benefits and risks
- understand her birth plan/preferences as early as possible so you can support her choices when it gets difficult.
What are some non-pharmacological pain relief options?
Comfort inducing measures
- Positioning, mobility, posture
- Use of water, heat, cold, showers, water immersion
- Massage, pressure * Encouragement
- Aromatherapy
- Meditation
- Affirmations
- Music
- Involvement of partners and other support people
- Relaxation-guided imagery
Others
- TENS
- Sterile water injections
- Acupuncture/Acupressure
- Homeopathy
Explain the non-pharmacological pain management of water immersion including its risks and benefits.
Water immersion includes a shower, and bath.
- around 35%
- submerge/cover over abdomen
- reduced pain perceived by women
- Can reduce the length of labour as it increase oxytocin and reduces stress hormones
Key benefits
- Heat relieves muscle spasm- therefore pain
- Relieves the effects of gravity and discomfort of pelvis
- Reduces anxiety
- Increase of natural opiates
- Reduces catecholamine secretion
- Woman feels in greater control
- similar to warm compress it promotes streaching of the perineum thus, reducing tear risks/severity
Complications
- cant use if have IV antibiotics, CTG monitored,
- infection
- pyrexia
Explain the non-pharmacological pain management of hypnosis/calm birth including its risks and benefits.
What is it?
- a method of managing pain and anxiety during childbirth, involving various therapeutic relaxation techniques
e.g. deep breathing and visualization
Benefits
- avoid pharmacologically pain relief options that come with other side effects
- greater maternal satisfaction
Complications/risks
- mother ay not remember first moments with baby as is still in the zone
The role of the midwife
- Protect the environment
- Respect woman’s choices
- Respect what she requests including the language you use.
Does it work?
- May be effective in reducing pain, increasing vaginal birth and reducing use of oxytocin
- Greater maternal satisfaction
Explain the non-pharmacological pain management of TENS amchine birth including its risks and benefits.
Transcutaneous Electrical Nerve Stimulation
- Electrical pulses prevent the pain signals from the uterus and cervix from reaching your brain
- Also stimulates the release of endorphins
- Best if used early in labour (Hamilton 2003)
- Insufficient evidence that it is more effective than placebo or other forms of pain management, no evidence of harm
- Anecdotal evidence = highly effective to a point
- Gives her something to do= distraction
What are the general benefits of non-pharmacological pain relief?
- Relatively safe
- Don’t interrupt balance of physiology, oxytocin production/progress of lanour
- Promote woman’s control of the process= promotes feeling safe
- Don’t interfere with woman’s memory of the process (unlike opiates do)
- Able to be participated in by other members of the support team
- Promotes sense of achievement
- Does not negatively impact baby (babys ability to BF, breathing etc)
What factors do non-pharmacological pain relief options rely on?
- Motivation to try them and keep trying them
- Physiology working
- Well woman
- Well-informed staff and support people
- Minimal interference (with light and assessments from the medical team)
- Trust in the process/ Mindset
What are the three main pharmacological pain relief options for labour?
- morphine
- epidural analgesia
- N2O:O2
