Asthma, most common, may occur first time during pregnancy
Attacks render fetus and mother prone to hypoxia
Pneumonia, leading indirect causes of maternal death in USA because the immune system of Mom is already depressed

Q

Vagina cavity

A

Inside is acidic owing to the breakdown of glycogen ( in the vaginal mucosa ) which creates a low pH environment inhibiting growth of bacteria.
This acid harms sperm killing off many because sperm is alkaline in nature.

28
Ectopic Pregnancy
Fertilized ovum becomes implanted somewhere other than the uterus Normal symptoms of pregnancy with severe abdominal pain All females with lower abdominal pain should be suspected of ectopic pregnancy
29
Rh Sensitization
Rh is a protein found on RBC's of most people. When woman who is Rh neg becomes pregnant by a man that is Rh positive, and the fetus inherits the factor, the fetal blood can pass into the woman's circulation and produce maternal antibody isoimmunization to the factor. (The fetus will and can be attacked by Mom)
30

Shoulder Dystocia
Difficulty in delivering shoulders Fetus cant breath if compacted with shoulders -Use McRoberts maneuver knees to the chest -apply pubic pressure on lower abdominal wall and may need to gently pull on patients head

33
Assisting Delivery
- crowning, gentle pressure on newborns head - support head when head exiting, do not pull on newborn. If membrane is still covering, tear membrane with hands - slip finger down neck to check for Nuchal cord - if nuchal cord, gently slip over head, if can't cut cord - clear airway with suction as soon as head exits - gently guide head upwards and downward for shoulders - delivered, maintain same level as vagina - wipe blood or mucus from newborn, suction mouth and nostrils, - dry newborn with towels, stimulate, suction and wrap with towels - record time of birth

35
Prolapsed Umbilical Cord
Cord emerges first before fetus - supine mom with hips elevated - 100% oxygen - pant with each contraction decreasing bearing down - push presenting part (not cord) back into vagina until no longer presses on cord - cover exposed portion of cord with dressings moistened in saline - maintain position and transport fast
36
Amniotic Fluid Embolism
When amniotic fluid and fetal cells enter woman's pulmonary and circulatory system
37
Delivery of Placenta
Bear down to expel placenta when following contractions occur Place placenta in plastic bag Examine perineum for lacerations and apply pressure to tears
38
Uterine Inversion
Placenta fails to detach and adheres to uterine wall when expelled resulting in prolapsed uterus -keep recumbent -100% oxygen -two IV lines with saline and titration -treat for shock -oxytocin to help hemmorage Attempt once to push uterus easily back inside. If this fails, cover portruding uterus with saline wet dressing

48
Breech Presentation
Butt first or limb first - flex knees of Mom - don't pull, but let butt deliver - once legs are out, support body - lower newborn to hang legs so body weight pulls itself - grab legs when head is visible lift up and down of legs and head should exit easily - if no head after 3 minutes, newborn in danger of suffocation. Insert v shaped fingers of newborns nose and mouth pressing against the vaginal canal until head is delivered - do not pull. If still not delivered rapidly transport maintaining newborns airway
