Q

what are normal maternal changes

A

Circulatory system: 10-20bpm increase, need for iron increases
Respiratory: increase in rate, diaphragm moves up into chest, consumption rate increases
Genital Tract: fundal grows a cm per week of pregnancy. 20 weeks, should be at belly button (umbilicus). Bladder has extra weight on it, urinate frequently
GI system: elevated progesterone = vomitting, also relaxation of smooth muscle - decrease gastric mobility = constipation
Metabolism: 10-20 percent increase in BMR (base metabolic rate), insulin resistance, fat deposition

Q

Stage 1 - Labour

A

dilation and effacement of the cervix
longest stage
begin with contractions that gradually increases in frequency, strength and length
fetus descends into pelvis (decrease in fundal height)
cervix softens, shortens, thins and dilates until at 10 cm

Q

Early Labour

A

you can still walk around fine
bloody show - pink, red or brown discharge
Spontaneous rupture of the membrane (SROM) - water breaks
contractions are mild and irregular
Contractions: F - far apart and irregular, L- short ~20-30 sec, S - mild

Can’t walk, to strong
SROM may or may not occur
bright red blood show
dilation to 10 cm progresses
vomiting, shaking, overwhelming emotions
Contractions: F - 3 to 4 min, L- 45 to 60 sec, S - moderate to strong

Q

Stage 2

A

Fully dilated to 10cm
Feels the urge to push
ends when baby is born
Contractions: F - 2 min or less, L - 60-90 secs, S- strong
uterus will change shape and rise up
bloody show, stool amniotic fluid drainage
bulging until presenting part Is visible

Q

Clinical considerations - When do we look?

A

dangle - umbilical cord
baby’s coming
decrease blood - vaginal bleeding is heavy and the pt is hypotensive or in shock
body parts decreased LOC

Q

Imminent birth as per ALS - how is it different between Primips and Multips

A

Primps - presenting par visible during and between contractions, maternal urge to push, contractions are less than two min apart
Multips - contractions 5 min apart of less and any other sings of second stage are present

22
Q

Stage 3

A

Birth of the baby to delivery of the placenta
Occurs 5-30 min after birth
Observation - lengthening of cord, sudden gush or trickle of blood, uterine contractions

23
Q

Placenta delivery

A

placenta will separate from uterine wall
apply gentle controlled cord traction (CCT) and guard the uterus with other hand
encourage delivery, ask mom to push
when delivered - inspect for wholeness, put in bag from OBS kit, label it with maternal patients name and time of delivery
HIGHEST RISK stage because of increase bleeding

24
How to prepare
get pt on a firm surface (if they don't want to move, leave them where they are prepare a neonatal resus station open OB kit dispatch for a second crew
25
Phase of a normal labour and delivery
decent flexion internal rotation extension restitution external rotation expulsion
26
Decent
Fetus moves down toward the pelvis and becomes engaged (duck waddle)
27
Flexion
fetal chin to chest
28
Internal Rotation
Fetal occiput turns toward maternal pelvis
29
Extension
Birth with head facing down
30
Restitution
baby's head rotates to the side
31
External Rotation
Fetus turns to deliver shoulder
32
Expulsion
Birth of baby
33
Cord Clamping
Clamp and hand width of baby's abdomen, cut the cord when it stops pulsating up to 2 minute mark ( wait till blood is no longer pumping, plus avoids mother from having anemia) No crying - cut the cord and CPR Multiple babies - Cute and deliver other baby
34
Uncomplicated Delivery Care
massage uterus to help minimize bleeding- should feel firm and central Check for bleeding every 5 min for the first 15 min monitor vitals encourage voiding to decrease the risk of postpartum hemorrhage keep newborn warm, skin to skin, breastfeed (if possible) monitor newborn using APGAR
35
Oxytocin - what does it do?
Increases the amplitude a frequency of uterine contractions, delays uterine blood flow and decreases cervical activity causing dilations and thinning of cervix
36
what are all the malpresentation that we can deliver?
Occiput anterior (face down) occiput posterior (sunny side up) breech transverse face compound brow
37
what are malpresentation that we CAN'T deliver?
Transverse Lie - head and breech can be felt with exam of abdomen Shoulder presentation - shoulder is presenting part Oblique Lie - fetus lies diagonal
38
Limb presentation, do we deliver?
Not possible to deliver, we discourage pushing, wrap the presenting limb and keep it warm while we transport
39
Brow presentation, how do they present?
the face is coming out first, its nose is leading they're way
40
Frank breech, what is it?
Hips flexed and legs extended, the butt is coming out first from the cervix
41
Complete Breech, what is it?
both hips and knees are flexed, both butt and feet enter the cervix first
42
Footling breech, what is it?
one hip and one knee flexes, the other is presenting out of the cervix.
43
How do you approach a breech presentation?
Hands off approach, just have your hands there to catch the baby, let gravity of the work, have mom on the end of the bed.
44
during the hands off approach, how does the timing work?
8 min for a full delivery 4 min from when you see the umbilicus 3 min when you see neck, at 1 min left, use the smellie veit maneuver
45
What is the smellie veit maneuver?
have a hand on the babies chest and two fingers exerting gentle pressure on the face to increase flexion place other hand on the baby's back with two fingers hooked to pivot around the symphysis pubis and allow the fave to be born
46
Cord prolapse, what do you do?
L&G, if there is a pulse, put cord gentle back in, ask mom if she wants to do it. if there is no pulse, put it back in and push the object to make it pulse again, use gravity to your advantage
47
what is the Exaggerated "sims" position?
On the side, with the R arm behind and the hips propped up by a pillow to have gravity working with you
48
What is a sing of shoulder dystocia?
turtle sign, the head comes out and back in because the shoulders are stuck
49
what does ALARM stand for?
Ask for help Lift legs, hyperflex thighs Adduct shoulders (apply suprapubic pressure) Rollover (all fours) Manual posterior arm (try to grab and torpedo) do x2 then leave
50
Postpartum Hemorrhage, when does it happen and what happens?
occurs either right after <24hrs or up to 12 weeks later Excessive bleeding is defined as 500 ml or more of blood. Severe PPH is at 1L Pt will be pale, confused, light headed, diaphoretic, in hypovolemic shock
51
PPH causes are the 4T's what are they?
Tone - exhausted uterus & cannot contract Tissue - parts of the placenta retained and clotting compromised Trauma - uterine rupture/lac during delivery Thrombin - coagulation abnormalities
52
How to treat PPH
Fundal massage - one hand on lower abdomen and use smooth circular movement to massage. Do for 10 - 15 min and Breast feed to help release oxytocin Bimanual Compression - one hand above symphysis pubis & other on top of fundus and squeeze together - for 5-10 minutes until bleeding stops
53
Meconium, what is it?
Newborns first stool/bowel movement
