Q

Onset of regular contractions, mild intensity
Cervix dilate and effaces but a little fetal dissent
Able to cope, smiling, talkative
Should not exceed 20 hours

42
Q

First stage

Active phase

A

Intensification of contractions
Fetal dissent is progressive
anxiety tends to increase, fear loss of control, decreased ability to cope
* Metabolic acidosis compensated by respiratory alkalosis
Cervix dilate from about 4 to 7 cm

43
Q

First stage

Significant anxiety, crying and yelling, hyperventilation and restlessness, “lose her mind”
Cervical dilation slows from 8 to 10 cm and rate of fetal dissent increases
Generalized discomfort, sensitivity to touch
Needs partner support or nurses
Hiccuping, belching, nausea or vomiting, perspiration on upper lip

44
Q

Positional changes a fetus

Flexion

A

As fetal head to sense, result of resistance, fetal chin flexes downward onto chest

45
Q

Positional changes a fetus

Internal rotation

A

Fetal HEAD must rotate to fit diameter of pelvic cavity, occiput rotates from LEFT to RIGHT (side to front) and sagittal suture aligns in anterioposterior pelvic diameter

46
Q

Positional changes a fetus

Restitution

A

Shoulders of infant enter pelvis obliquely, neck becomes twisted. Once head emerges, neck untwist turning head to one side and aligns (restitution) with position of back in birth canal

47
Q

Positional changes a fetus

External rotation

A

Shoulders rotate to the anterior posterior position and pelvis head is turned farther to the side

48
Q

Positional changes a fetus

Expulsion

A

After external rotation, anterior shoulder is born before posterior shoulder, body follows quickly

49
Q

Third stage

Placental separation signs

  2. Rise a fundus in abdomen
  3. Sudden gush or trickle of blood
  4. further protrusion of umbilical cord out of vagina
50
Q

Third stage

Placental delivery

A

Retained placenta – more than 30 minutes elapsed

  • Shultze Mechanism: expelled with fetal shiny side presenting,” shiny shultze”
  • Duncan Mechanism: expelled with maternal surface delivering first, surface is rough, “dirty Duncan”
51
Q

Fourth stage

A

One to four hours after birth
Physiologic readjustment of mothers body begins
VS: drop in blood pressure, increased polls, moderate tachycardia
May experience shaking chill
Hemodynamic changes
Acid/base is more balanced

Half-life of 4.5 hours
For sleep to encourage rest

54
Q

Diazepam (Valium)
Midazolam (Versed)
Benzodiazepine

A

Treat anxiety, anticonvulsant action
Fetal side effects: increase in variability of FHR, hypotonicity, hyperactivity, impaired temperature regulation, impaired metabolic response to cold stress
Not recommended before baby is born
Associated with low Apgar scores when administered five minutes or less before birth

55

Promethazine (Phenergan)

A

Sedative, antiemetic

Crosses placenta barrier and result in decreased FHR variability

56
