Overview of today’s presentation • • • • Two main approaches to maternity care How these affect outcomes for mother and baby Conclusions regarding normalcy of birth today The doula’s role in normalizing birth Birth Never Changes • Throughout time, in all countries & cultures, the physiologic process of birth is the same as it has always been. Canadian Task Force: “What is Normal Birth?” • Natural means “existing or derived from nature; not made, caused by, or processed by humankind.* Childbirth is ‘natural’ if there is little or no human intervention.” Birth Today– Two Approaches • Birth as Nature Intended ▫ Psychophysiologic (“mind-body”) Management • Industrialized (Medicalized) Birth ▫ “obstetric package” Psychophysiologic Management • Designed to maintain and enhance the woman’s resources for giving birth ▫ Psychological ▫ Physiological • Based on these premises ▫ Woman’s state of mind influences labor process ▫ Her participation increases good outcomes ▫ Low intervention and cesarean rates are desirable Industrialized (Medicalized) Management • Designed to replace or alter the body’s own resources with med/tech interventions • Gives more control over the birth process • Based on these premises ▫ The normal process is unreliable or unsafe ▫ Overall, outcomes are improved with a package of routine interventions ▫ Requires less skill for difficult births, easier to teach ▫ Inductions, cesareans are no worse and may be better for mother or baby than normal birth What Price are We Paying? • As cesarean and induction (without medical indication) rates rise, key indicators of quality care worsen-- Original intention – to improve outcomes Now that it has become “usual care,” are outcomes improving? What is “Normal Birth?” • Defined by physiology? ▫ The “physiological norm” does not change. • Defined by typical care practices – the “statistical norm?” ▫ Changes constantly, with geography, culture, and institution • Is this association causal or coincidental? ▫ Influenced by new knowledge, technology, societal trends • If epidural rate is 85%, it is the norm, but is it normal? Why is the distinction important? • The physiological norm -- standard against which all care practices must be measured. ▫ How and how much is the normal process altered? ▫ How are outcomes affected? ▫ What are the tradeoffs? • Maternity services can be rated by how closely they adhere to principles of physiological birth. A 2011 report of insurance billing records for 2008 Childbirth Connection’s Analysis Childbirth Connection’s conclusions • “Complicating conditions” high rates of minor or modifiable risk factors and preventable coomplications • High prevalence of diagnoses based on unreliable screening tests or subjective clinical judgment • Caused by overuse of questionable medical procedures (induction, C/S, episiotomy • Payment tied to number or procedures – incentive to dx high risk & disincentive to promote health and prevention • Our current Maternity Care payment and reporting system causes misleading and inflated views of risks of childbearing • See Childbirth Connection’s “Blueprint for Action: Steps toward a High-Quality High-Value Maternity Care System http://transform.childbirthconnection.org/blue print. 21 How does place of birth affect labor? • A “safe” undisturbed environment supports spontaneous behavior and facilitates secretion of oxytocin (“love hormone”) • A strange environment with invasive noisy equipment is disturbing and may increase anxiety and catecholamine production Compare usual “medicalized practices with “physiologically normal” practices ▫ Interferes with effects of oxytocin ▫ Slowed labor, adverse fetal response 23 How does the caregiver affect labor? • Midwifery: ▫ Fewer costly, risky interventions ▫ Attention to women’s psychosocial needs ▫ Better outcomes for selected populations • Obstetrics: ▫ A surgical specialty ▫ Appropriate for high risk situations ▫ Less personal care, more reliance on tests and technology 25 How does the way labor begins affect labor? • Spontaneous – ensures fetus’s readiness for life outside mother’s uterus • Elective induction increases ▫ ▫ ▫ ▫ Late term prematurity NICU admissions, mother-baby separation Labor time in hospital Cesareans for fetal distress, failed induction in nullips ▫ Postpartum hemorrhage 27 How does continuous support affect labor? 29 How does hydration affect labor? • Continuous doula support increases • Intravenous hydration may lead to— ▫ Spontaneous vaginal birth ▫ Maternal satisfaction with birth ▫ Psychological well-being ▫ Inconvenience and discomfort for mother ▫ Fluid overload, hyponatremia, foot and hand swelling that lasts for days ▫ Mother feeling deprived of basic comfort • Continuous doula support decreases • Drinking her choice of liquids ▫ Pain medications use ▫ Surgical delivery (cesareans, instruments) ▫ NICU admissions ▫ Enhances sense of normalcy for mother ▫ Usually adequate in normal labor • Caution: Too much oral fluid can lead to fluid overload and prolonged labor…. • “Usual care” – just the opposite 31 How does care of the amnionic sac affect labor? How does type of monitoring affect labor? • Electronic fetal monitoring associated with ▫ ▫ ▫ ▫ 33 • Artificial rupture of membranes (ROM)- More C/S for non-reassuring FH Tracings No improvements in newborn outcomes** Restrictions of mother’s activity Inability of cg to auscultate FHT ▫ May speed labor (by average 40 min.) ▫ May cause a pre-existing fetal malposition to become persistent ▫ Increases chance of infection • Spontaneous ROM • Auscultation is less disturbing to the mother, and • Auscultation has as good outcomes as EFM ▫ Usually occurs late in 1st stage or in 2nd ▫ May enhance chance of rotation to OA 35 How do pain & medications affect labor? • Suffering may increase likelihood of trauma and PTSD • Narcotics ineffective and unpleasant • Epidural reduces pain, but not suffering; • Is invasive and unsafe without precautions and interventions • Side effects – ▫ low blood pressure, fever, fetal malposition and distress, urine retention, slow progress 37 How do positions and movement affect labor? • Supine position or restriction of movement ▫ Increases dystocia, malposition, pain, fetal distress, maternal stress • Freedom of movement and choice of position ▫ Increases comfort, decreases above effects ▫ Enhances maternal satisfaction ▫ Some studies find shorter labors 39 How do pushing positions affect labor? • Supine position (most common in NA) ▫ Narrows birth canal, increases effort needed to birth baby ▫ Increases vacuum, forceps deliveries ▫ Increases pelvic floor damage, episiotomy ▫ Prolongs 2nd stage • Non-supine positions & mother’s choice ▫ Increase chance for spontaneous birth ▫ Reduce pelvic floor damage ▫ Increase mother’s satisfaction How does perineal care affect birth? • Routine episiotomy ▫ More 3rd and 4th degree lacerations ▫ Prolonged postpartum pain & healing ▫ No benefit to mother or baby, except rarely • Avoidance of episiotomy ▫ 30 – 50% intact perinea ▫ If combined with non-supine positions and spontaneous bearing down, few long-term pelvic floor problems ▫ Less pain, faster healing 41 How do pushing techniques affect labor? • Prolonged breath holding & straining ▫ Increases fetal distress ▫ Increases pelvic floor damage ▫ Increases long-term problems of pelvic floor relaxation • Delayed or spontaneous bearing down ▫ More intact perinea & spontaneous births ▫ Fewer 3rd & 4th degree tears ▫ Improved fetal well-being How does surgical birth affect outcomes? • May prevent serious problems for mother or baby • Sometimes necessitated by earlier interventions • V-E/ forceps ▫ Damage to mother’s perineum ▫ Swelling, bruising of baby • Cesarean ▫ ▫ ▫ ▫ ▫ All the risks of major abdominal surgery Increased maternal problems in future childbearing Prolonged time required for neonatal adaptation Prolonged maternal recovery Delayed or compromised mother-infant interaction 51 How does natural birth affect outcomes? • To mother ▫ Hormonal enhancement of positive maternal feelings & behaviors ▫ Usually quicker recovery time • To baby ▫ Optimal condition at birth (no need to recover from medications, procedures) • To both ▫ Mutual regulation between mother and baby Temperature Breastfeeding • To family ▫ Ready and able to adjust to their new roles together ▫ JOY!!! How does timing of cord clamping affect baby? • Immediate clamping & cutting ▫ Enables removal of baby to warmer, ▫ Doesn’t prevent jaundice, as believed • Delaying clamping for 2 min. or more ▫ Allows physiologic transfusion of blood between baby and placenta ▫ Improves infant hematologic status at 2 and 6 months (i.e., less anemia) ▫ Encourages close mother-infant contact 55 How do the first days after birth affect mother and baby? • Mother and baby together promotes ▫ Establishment of “on cue” breastfeeding ▫ Mutual regulation of temperature ▫ Maternal behavior • Father-baby skin-to-skin contact in first day and after promotes protectiveness and closeness toward baby • Separation increases newborn distress and maternal depression or detachment World Health Organization criteria for normal birth • • • • Spontaneous onset, 37-42 wks Low risk at start & remaining so Spontaneous birth of vertex Mother & baby in good condition • “Normal birth” – a diagnosis made in retrospect Numerous definitions. . . (We’ll focus on two definitions) What is Normal Labor? (cont.) •Gould (midwife) adds to WHO: ▫ Labor and birth involves strenuous physical work by mother, ▫ Includes movement by mother (seeking comfort & progress), and ▫ Movement by fetus through the birth canal •“Movement and the notion of hard work are crucial to a midwifery understanding of normal labor.” --D. Gould, J Adv Nurs, 2000 Psychosocial Outcomes of Normal Labor (Gould) • A healthy mother and baby who are ready to adjust together to their new roles; • Empowerment of the woman • Sense of achievement from her own productive efforts and her ACTIVE control (rather than passive role) in the birth. Supporting & Preserving Normal Birth • Besides playing the role proven to be effective in improving outcomes… • Model confidence in the physiological process, not a sense of urgency or need to control it. Watch before acting. ▫ Patience and confidence: “Babies come out:” Help her accept her labor pattern. “Labor unfolds at its own pace.” • Easier said than done. . . Supporting & Preserving Normal Birth Supporting & Preserving Normal Birth Think of your own practice. Do you Feed or lead her desire to start labor? Urge her to keep moving, changing positions, to hasten labor, even if progress is occurring? Suggest bath to stop labor that begins at night? Do you suggest that labor may not be proceeding normally with words or actions? Are you uncomfortable not “doing something?” • We mustn’t rush the woman or the process, as long as mother and baby are doing well. • This does not mean that we never intervene with suggestions, encourage activity • Guidance, not commands or management • It means we are relaxed and patient, because this reinforces her confidence ▫ We are not controlling or authoritative, unless we really need to be ▫ When there’s a deadline or a problem, then we act! “How Normal is Birth Today?” The Normal Birth Supporter’s Motto If it ain’t broke, don’t fix it! Conclusions • What will be the impact on the human species if giving birth and being born are removed from the life cycle? • Does it matter? • Rarely do women have normal births in the countries of North America or in most other countries.
