38 First Trimester Review The Whole Period of Pregnancy Can Be Divided Into Three StagesThe first trimester (early pregnancy): 1-12wThe second trimester (middle pregnancy): wThe third trimester (late pregnancy): 28-40w
39 1. History and symptoms A. Cessation of menstruation This is the first frequent symptom of pregnancy, althougha few women may have slight bleeding after conception.Amenorrhea is not only due to pregnancybut also other reasons.Women of breast feeding may be pregnantbefore the recovery of menses.
40 B. Nausea and VomitingAlso called morning sickness because they occur upon arising. These symptoms appear one or two weeks after the period is missed and last until 10th to 12th week, its severity varies from mild nausea to persistent vomiting (e.g. Hyperemesis gravidarum).
41 C. Urinary symptomsIncreased frequency of urination is due to increased circulation associated with the effect of estrogen and progesterone on the bladder, combined with pressure by the gradually enlarged uterus on the bladder.
42 D. MastodyniaIt may be present in early pregnancy and ranges in severity from a tingling sensation to frank pain.
43 2. Signs Breast changes Breast enlargement and vascular engorgement. Nipple and areola become blacker.Enlargement of the accumulated sebaceous glandsof the areolas (Montgomery’s tubercles) may be noted.
44 Changes of the reproductive organs Vagina: The vaginal wall become discoloration as the pelvic blood vessel becomes congested.Cervix: Cyanosis and a gradual softening due to congestion.
45 Uterus: Enlargement and softening. The isthmus of the uterus is also soft and can be compressed between the fingers palpating vagina and abdomen (Hegar’s sign).After the 12th week, the fundus of the uterus is usually palpable above the symphysis pubis.
46 3. Supplementary examination Pregnancy testThe laboratory test for pregnancy are based on theidentification of human chorionic gonadotropin (hCG),which can be detected as early as 7-9 days after fertilizationby high sensitive technique.The samples may be blood or urine.
47 Basal body temperature (BBT) A persistent elevation of BBT for longer than 18 daysmay be presumptive evidence of pregnancy.
48 Progesterone is given to a women with amenorrhea. Progesterone testProgesterone is given to a women with amenorrhea.If she is pregnant, no bleeding will follow, otherwise,bleeding should occur within 7-10 days of progesteroneadministration.This is reliable in the nonpregnant patient only ifthere is adequate estrogen stimulation of the endometrium.
49 UltrasonographyThere are trans-vaginal and abdominal Ultrasonagraphys.A gestational sac can usually be identified at 5-6 weeksafter the beginning of the last period.Fetal heart beating can be detected by about 7th week andthe fetus itself can be seen by about the 8th week.Doppler is also an ultrasound technique,which diagnoses the pregnancy by revealing the heart beating.
52 Nausea, vomiting, frequency of micturition subside SymptomsNausea, vomiting, frequency of micturition subsideAmenorrhea continuesQuickening: perception of active fetal movement by women(From 18th week)Progressive enlargement of lower abdomen by the growing uterus
63 16th week: midway between symphysis pubis and umbilicus 22~24th week: at the level of umbilicus28th week: at the junction of the lower 1/3 and upper 2/3 of the distance between the umbilicus and ensiform cartilage
65 Braxton-Hicks Contraction In 1872, John Braxton Hicks investigated the laterstages of pregnancy and noted that many women feltcontractions without being near birth.This process was usually painless but caused women confusionas to whether or not they were going into actual labor
66 CauseBraxton Hicks contractions are a tightening of the uterine muscles for one to two hours and are thought to be an aid to the body in its preparation for birth.
67 Alleviating factors Rhythmic breathing Lying down on the left side A slight change in movementUrination
68 Very early, the uterus undergoes spontaneous contraction Firmer at one moment and soft at anotherCan be excited by rubbing the uterusIrregular,infrequent, spasmodic, and painessNear term, frequent with increase in intensity, discomfortMerge with the labor
69 Palpation of fetal parts Diagnosis of pregnancyIdentify the presentation and position of fetus
71 Active fetal movements Positive evidence of pregnancy & live fetusFaint flutter→stronger movement
72 External ballottement Be elicited as early as 20th weekObese women & scanty liquor amniiby a push to the foetal parts with one hand abdominallyand the other hand receiving the impulse
73 Ballottement is a medical sign which indicates increased fluid in the suprapatellar pouch over the patella at the knee joint. To test ballottement the examiner would apply downward pressure towards the foot with one hand, while pushing the patella backwards against the femur with one finger of the opposite hand.
90 SignsFetal heart sound can be heard at rate varies from 120 to 160 beats per minute.The fetal body can usually be palpated by the 18th to 20th week of gestation unless the patient is too fat, the abdomen is tender or there is an excessive amount of amniotic fluid.
95 Symptoms: Amenorrhoea Enlargement of the abdomen Lightening: due to the engagement of the presenting partFrequency of micturitionFetal movement
96 Cutaneous changes: increased pigmentation and striae Sign:Cutaneous changes: increased pigmentation and striaeUterine shape: cylindrical to spherical beyond 36th weekFundal heightBraxton-Hicks contractionFetal movementPalpation of the fetal parts
100 After 24 weeks, the SFH measured in cm After 24 weeks, the SFH measured in cm. correspond to the number of the weeks up to 36 weeks.A variation of ± 2 is accepted as normal.Variation beyond the normal range needs further evaluation.
