Placenta previa is an obstetric complication that can occur in the second
or third trimester of pregnancy .
It can some times occur in the latterpart of the first trimester. It is a leadingcause of antepartum hemorrhage (vaginal bleeding)
characterized by the implantation of theplacenta over or near the top of the
cervix .

Placenta previa is classifiedaccording to the placement ofthe placenta :
Type I or low lying: The placenta encroaches the lowersegment of the uterus but does not infringe on thecervical os.Type II or marginal: The placenta touches, but does notcover, the top of the cervix.Type III or partial: The placenta partially covers the top
of the cervix.Type IV or complete: The placenta completely covers thetop of the cervix. This type of praevia often will notbleed until labour starts.

Medical Intervention
Immediate delivery of the fetus Blood volume replacement (to maintain blood
pressure) and blood plasma replacement (to maintainfibrinogen levels) may be necessary.
In cases of fetal distress, a Ceasarean section isindicated.
Vaginal delivery.There are two ways of doing this with a placenta
previa:
1. The baby's head can be brought down to theplacental site (if necessary with Willet's forceps or avulsellum) and a weight attached to his scalp
2. A leg can be brought down and the baby's buttocksused to compress the placental site.

Abruptio placenta
is the separation of the placental lining from the uterus of a female .
it refers to the abnormal separationafter 20 weeks of gestation and prior tobirth.

Abruptions are classified according to severityin the following manner:
Grade 0: Asymptomatic and only diagnosed throughpost partum examination of the placenta.
Grade 1: The mother may have vaginal bleeding with milduterine tenderness or tetany, but there is nodistress of mother or fetus.
Grade 2: The mother is symptomatic but not in shock. There issome evidence of fetal distress can be foundwith fetal heart rate monitoring.
Grade 3: Severe bleeding (which may be occult) leads tomaternal shock and fetal death. There may bematernal disseminated intravascularcoagulation. Blood may force its way throughthe uterine wall into the serosa, a condition
known as Couvelaire uterus .

Causes: unknownRisk factors Maternal hypertension is a factor in 44% of allabruptions. Materna l trauma, such as mo tor vehicle accidents ,
assaults , falls, or nosocomial Drug use is a factor, particularly tobacco , alcohol ,
and cocaine . Short umbilical cord Prolonged rupture of membranes (>24 hours) Retroplacental fibromyoma Maternal age: pregnant women who are younger
than 20 or older than 35 are at greater risk. Previous abruption: Women who have had an
abruption in previous pregnancies are at greaterrisk.
Multipara : Women who have given birth many timesare at greater risk.

Medical Intervention
..Monitor the fundus.
..Give Rhogam if mother is Rh negative .
..Immediate delivery of the fetus may beindicated if the fetus is mature or if the
fetus or mother is in distress...Blood volume replacement...Blood plasma replacement..Vaginal birth is usually preferred over
caesarean section unless there is fetaldistress.

Nursing Intervention1.Primarily, continue evaluate maternal and fetal physiologic status
particularly.Vital signs Bleeding Electronic fetal and maternal monitoring tracings Signs of shock rapid pulse, pallor, cold and moist skin decrease
in blood presureDecreasing uterine output
2. Never perform vaginal or rectal examinations or take any actions
that would stimulate uterine activity.3. Assess the need for immediate delivery.4. If the client is in active labor and bleeding cannot be stopped
with bed rest, emergency cesarean delivery may beindicated.5. Provide bed rest in lateral position.
6. Insert a large gauge intravenous catheter into a large vein forfluid replacement.7. Obtain a blood sample for fibrinogen levels.8. Monitor the FHR. 9. Measure maternal vital signs every 5 to 15
minutes.10. Administer oxygen to the mother via mask and prepare for
cesarean section.11. Address emotional and psychosocial needs.

Eclampsia
is a serious complication of pregnancy and is characterized by convulsions.Usually eclampsia occurs after theonset of pre-eclampsia thoughsometimes no pre-eclamptic symptoms
are recognizable.Cause: unknown

23/63
Signs and symptomsThe majority of cases are heralded by pregnancy-
induced hypertension and proteinuria but the only true
sign of eclampsia is an eclamptic convulsion, of whichthere are four stages.
Premonitory stage This stage is usually missed unless constantly
monitored, the woman rolls her eyes while her facialand hand muscles twitch slightly.
Tonic stage
After the premonitory stage the twitching turnsinto clenching. Sometimes the woman may bite hertongue as she clenches her teeth, while the arms andlegs go rigid. The respiratory muscles also spasm,causing the woman to stop breathing. This stagecontinues for around 30 seconds.

Clonic stage The spasm stops but the muscles start to
jerk violently. Frothy, slightly bloodied salivaappears on the lips and can sometimes beinhaled. After around two minutes theconvulsions stop, leading into a coma , but some
cases lead to heart failure .
Comatose stage The woman falls deeply unconscious,
breathing noisily. This can last only a fewminutes or may persist for hours.

RISK FACTORS1.A woman's previous history of preterm birth, or
pregnancies that ended in miscarriage .2.Multiple pregnancies ( twins, triplets, etc.) are at a higherrisk for premature birth.Uterine or cervical abnormalities.
3.Certain chronic disease such as high blood pressure ,kidney disease and diabetes .
4.Infections of the cervix, uterus or urinary tract . CertainSTDs, Beta Strep .
5.Substance abuse of tobacco , alcohol and other drugs .
Women who have tried to conceive for more than a yearbefore getting pregnant are at a higher risk for prematurebirth. Women under 18 or over 35 are at a higher risk forpremature birth.

of preterm birth more than 4 times. Asa matter of fact this is one of the mostserious risk factors, that is completelypreventable.

Signs and Symptoms1. Four or more uterine contractions in one
hour, before 37 weeks' gestation.2. A watery discharge from the vagina
which may indicate premature rupture
of the membranes surrounding thebaby.3. Pressure in the pelvis or the sensation
that the baby has "dropped".
4. Menstrual cramps or abdominal pain.5. Pain or rhythmic tightening inlower abdomen or back.
6.Vaginal spotting or bleeding .

Medical Intervention There are two tactics that can be used to deal with a
potential premature birth:A.delay the arrival of birth as much as possible,
or B. Prepare the prospectively premature fetus for
arrival.
Both of these tactics may be used simultaneously. The first resort is usually complete bed rest. Proper nutrition and especially hydration are
important. In a hospital setting, a drug-free IV drip may be used
to try to stop premature labor simply by improvingthe mother's hydration .
Administer anti- contraction medication s (to colytics ),such as ritodrine , fenoterol , nifedipine and atosiban .

Placenta accreta is a severe obstetric complication involving anabnormal at tachment of the placenta to themyometrium (the middle layer of the uterine wall ).
Placenta increta occurs when the placenta extends into the muscle ofthe uterine wall and happens in around 17% of allcases.
Placenta percreta the worst form of the condition and occurring in 5 -7% of cases, is when the placenta penetrates theentire uterine wall. This variant can lead to theplacent a attaching to other organs such as thebladder .

Uterine rupture
is a potentially catastrophic eventduring childbirth by which the integrity
of the myometrial wall is breached.In an incomplete rupture theperitoneum is still intact.
With a complete rupture thecontents of the uterus may spill intothe peritoneal cavity or thebroad ligament .
