Obstetrics – Clinical Diagnosis Obtain a full history from a pregnant woman
Demonstrate sensitive communication with female patients Ability to distinguish relevant aspects of history Ability to take an accurate menstrual history Ability to assign risk status to a particular pregnancy Demonstrate knowledge of health promotion issues during pregnancy
HPI Establish pregnancy if unknown status – delayed menstruation (up to a week, on a
background of previous normal cycles), date of the last period, evidence of morning sickness, if a home pregnancy test has been used, has it been confirmed by ultrasound? Other symptoms include breast pain and presence of foetal movement.
History of present pregnancy: o Mother’s age o Date of last menstrual period o Weeks gestation o Expected delivery date o Planned?
o Symptoms / complications during pregnancy (of importance is: pelvic/abdo pain vaginal bleeding cramping – suspicion of ectopic or abortions. Vaginal discharge (infection) fluid leakage (ruptured membranes) also important Some routine problems of pregnancy include
back pain constipation dehydration oedema urinary frequency
Foetal movement (usually by 16-20 weeks) Blurred vision, headache, rapid weight gain Any prenatal care received up until now?
Menstrual history: Date of last menstrual period Age of menarche Regularity Abnormal bleeding (amenorrhea, dysmenorrhea, etc) Heavy bleeding / spotting / breakthrough bleeding Prior use of the OCP
Past History Obstetrics history of prior pregnancies –
o Dateo Outcomeo mode of deliveryo length of time in labouro birthweighto any complications.
Sexual history – STDs, dyspareunia. Other relevant past medical / surgical history. Medications – prior to and during pregnancy. Allergies
Family History Congenital problems (mother & father’s family) Other relevant family history (hypertension, IHD, DM) Social History Tobacco / EtOH history Recreational drugs Occupation of both parents
Examination of a pregnant woman
Ability to palpate pregnant abdomen and interpret findings
(“Would you like me to examine the patient’s vital signs?” – HR, RR, temp) Blood pressure + weight (again, ask examiner if this should be measured) Abdominal palpation:
o Abdominal inspection (scars, abnormal distension, etc.) o Foetal movement o Uterine tenderness o Fundal height (from the top of symphysis pubis.
At 12 weeks, fundal height should be at the pubic symphysis. At 16 weeks, it should be midway between symphysis & umbilicus. At 20 weeks, at the umbilicus. At 20-32 weeks, fundal height in centimeters above symphysis should equal
gestational age in weeks. Use a measuring tape Check for foetal position (>32 weeks): vertex, breech or transverse. Foetal heart tones – listen with bell of stethoscope (normal range is 120-160
bpm. Present usually after 20 weeks). Deep tendon reflexes Oedema Dipstick urine protein (ask examiner)
Foetal Heart Sounds Area of the mother’s abdomen where foetal heart sounds best heard depends on position
of foetus & degree of descent into pelvis.- Cephalic presentations, foetal heart best heard below umbilicus- I. Occipito anterior – near midline- II . Occipito transverse – further towards mother’s side- III. Occipito posterior – in the flank (towards mother’s back)
- Breech presentation: at or above level of umbilicus
Examination of a woman in labour Knowledge of parameters of assessing progression of labour Ability to communicate effectively with birth partners Demonstrate strategies to soothe an anxious patient
Foetal lie – whether infant is longtitudinal or transverse. Palpate bimanually the fundus, either side of the uterus, and the presenting part above the pubic symphysis (Leopold maneuvers).
Foetal presentation – vertex or breech. Using same technique, however this is more difficult and may require ultrasound to confirm.
[ Suspected membrane rupture – speculum exam with pool, nitrazine and fern tests (to diagnose amniotic fluid) ]
Cervical exam: o 1 – Dilation (fingers to assess how open cervix is at level of internal os: 10 cm is full
dilation) o 2 – Effacement (subjective measurement of how much length is left of the cervix) o 3 – Station (distance from level of ischial spines of the most descended aspect of the
presenting part. If at level of spines, station = 0) o 4 – Consistency (cervix firm/medium/soft?) o 5 – Position (cervix posterior/mid/anterior?)
Foetal presentation & position: o Presentation can be palpated during cervical exam (eg. hair/sutures vs gluteal
cleft/anus) o Position: In the vertex presentation, can be done by palpation of the sutures.
Distinguish between occiput & posterior fontanelle vs posterior fontanelle, and describe accordingly (pg. 23, blueprints book).
Stages of labour: o 1 – Onset of labour until complete dilation of cervix. o 2 – Full dilation until delivery of infant o 3 – After delivery of infant until delivery of placenta
Cardinal movements of labour: o Engagement: foetal presenting part enters pelvis
o Flexion: of head, to allow the smallest diameter to present to pelvis o Descent: of vertex with passage of head down into pelvis o Internal rotation: following descent into midpelvis o Extension: as vertex passes beneath and beyond pubic symphysis. o External rotation: after the head delivers.
Assessment of fetal well-being Demonstrate ability to use Pinard stethoscope
Pinard stethoscope is used to monitor foetal heartbeat every 15-30 min during Stage 1 of labour, and following every contraction during Stage 2. More common nowadays to use hand-held ultrasound (SonicAid).
Demonstrate ability to take CTG readings using:o External padso Scalp electrode **
Main use for the CTG is information regarding variations in foetal heart rate, measuring the frequency of contractions, and comparing contractions with the foetal heart rate tracing to determine the type of decelerations occurring.
Foetal heart rate tracing: o Determine baseline is within normal range (between 110-160 bpm). o Above 160 bpm, foetal distress secondary to infection, hypoxia or anaemia is of
concern. o A flat tracing is also non-reassuring (hypoxia, various drugs)o As is increased “sinusoidal” variability (foetal asphyxia, foetal anaemia) o Beat-to-beat variation is normally 2-3 bpmo Long term variability (over 15 secs) = 10-15 bpmo Should be at least 3-5 cycles/min around baselineo Tracing considered formally reactive if there are 2 accelerations above baseline
which last for at least 15 secs within 20 mins. Decelerations:
o Early: Begin and end ~ at the same time as contractions. Result from increased vagal tone due to head compression during contraction.
o Variable: Can occur at any time Result from umbilical cord compression. Repetitive variables seen when cord wrapped around neck or within shoulder
(and compressed with each contraction). o Late:
Begin at peak of contraction and slowly returns to baseline after contraction result of uteroplacental insufficiency.
Mnemonic for assessing foetal well-being: DR C BRAVADO o Determine Risk - Assess prenatal and intrapartum risk factors and labor progresso Contractions - Adequate? Hypertonic? o Baseline RAte - Should be 110-160 BPM, requires 10min monitoring to establish;
bradycardia = < 110; severe bradycardia = < 100; tachycardia = > 160, severe tachycardia = > 200 (note; the latter can be from fetal congenital heart disease)
o Variability: Normal = 10-15BPM around baseline More accurately assessed w/FSE Best predictor of good fetal outcome (better than accels); Decreased with sleep, hypoxia, acidosis, prematurity, CNS anomalies, and
drugs including narcotics o Accelerations:
Requires > 15BPM over baseline x > 15sec; presence is reassuringo Decelerations--Must correlate with timing of contractions to classify o Overall assessment
Foetal scalp electrode: o Used in the case of repetitive decels or if foetus difficult to trace externally with
doppler. Small electrode attached to foetal scalp. Tracing is more sensitive in beat-beat variability and in no danger of being lost during contractions (where the foetal heart position may change).
Foetal scalp pH: o if tracing nonreassuring, this can be used to directly assess foetal hypoxia and
acidemia. o Reassuring if pH > 7.25o Indeterminate between 7.20-7.25o Non-reassuring if < 7.20.
Obstetrics – Investigations Pregnancy testing
Ability to carry out a urinary pregnancy test Many home pregnancy tests have a high sensitivity and will be positive around the time of
missed menstruation (as early as 8-9 days after ovulation). These test for beta-hCG, produced by the placenta shortly after implantation into the uterus,
peaking by 10 weeks of gestation. When using a urinary pregnancy test, patient will either need to urinate in a cup (with
midstream urine) and then place a small amount of urine, using a dropper, into the testing well (or urinate directly on a testing stick).
Most of the tests have two windows –
o one that tells if the test has been performed correctly (control) o one that gives the positive or negative result. o In the result window, the tests usually give a line or a plus. For the line tests, any
colored line, no matter how faint, in the result window during the alotted time is a positive result, meaning the urine contains hCG.
Demonstrate knowledge of quantitative HCG assessment
Another alternative is a quantitative beta-hCG blood test, measuring amount of hCG in the blood (compared with a qualitative test which determines the presence or absence of hCG).
Ante natal investigations
Ability to take an adequate blood pressure

ultrasound (18-20 weeks) – o number of foetuses in uteruso foetal ageo physical developmento placental positiono amniotic fluid around foetus
3rd trimester: o Haematocrito glucose loading test.o Group B strep culture (36 weeks)
Screening for congenital/genetic abnormalities: CVS: 11-13 weeks (0.5% risk of miscarriage) Amniocentesis: 15-18 weeks (0.25% risk of miscarriage) Nuchal translucency + blood test (free-beta-hCG, PAPP-A):
o 12 weeks, Down Syndrome. CF carrier test: DNA from buccal cell sample (mouth swab) CTG criteria & normal vs abnormal CTG traces: refer to above (foetal well-being)

Ultrasound investigations
Demonstrate a systematic approach to looking at ultrasound photographs Ability to check name and date and tell orientation of US Demonstrate ability to determine foetal position and presence of fetal heart
Check name of patient, date of US, gestational age (if known) Assess regional coverage: do the images cover the region required? Assess exposure: are all of the tissues to be imaged sufficiently bright for diagnosis? Assess patient positioning: have the images been obtained in the correct plane? Examination of the image in detail:
o foetal positiono foetal lieo placental locationo foetal anatomical survey.
Ultrasound is the only frequently performed imaging technique in obstetrics.o Indications (in general)
Diagnosis of early pregnancy 5/40 – gestational sac 6/40 fetal heart
Bleeding in early pregnancy (threatened abortion, ectopic) Determination of gestational age/foetal size/foetal number Placental location Identification of foetal malformations Abnormal size for dates (polyhydramnios & oligohydramnios) Diagnosis of foetal death Assessment of foetal well-being Confirmation of presentation (eg. vertex vs breech)
o Indications (specifically): Early pregnancy:
Confirmation of pregnancy: gestational sac containing embryo (with heartbeat by 5 wks)
Investigating pain or bleeding associated with suspected abortion or ectopic.
Middle pregnancy: Anatomical surveys to rule out congenital malformations Placental location Foetal age Prior to CVS, amniocentesis, nuchal translucency screening.
Late pregnancy: Assessment of suspected IUGR & foetal distress. Malpresentation Review of foetal anamoly
Demonstrate knowledge of the limitations of ultrasound investigation
Relatively free of hazards. Whilst some artefacts can occur, the do not usually detract from the quality of the image
obtained. Image detail significantly reduced by obesity and abdominal scars. High quality detail may not be present with older scanning equipment.

cervix with other hand) Feel shape, consistency, mobility, identify tenderness or masses.
o Assess pelvic muscles: 2 fingers drawn out clear of cervix and spread. Patient should be able to contract them together for 3 seconds.
o Rectovaginal examination: Index in vagina, ring in rectum Allows palpation of retroverted uterus
Knowledge of the methods of investigation of urinary incontinence **
Urinalysis and urine culture:o To rule out infection
Neurological examination:o Perineal sensationo Pelvic floor contractiono Reflexes:
deep tendon anal bulbocavernosal
Standing stress test:o Patient (full bladder) stands over a towel or sheet with feet a shoulder width apart.o Patient coughso Dr observes for leakageo Can be done in lithotomy position as an alternativeo Low sensitivity and specificity
Cotton swab testo To Dx a hypermobile bladder neck with genuine stress incontinenceo Insert lubricated swab into urethra to the angle of the urethrovesical junction (UVJ)o Patient strains as if urinating: UVJ descends and the swab moveso Normal angle is < 30 degrees from horizontalo 30-60 degrees associated with a hypermobile bladder neck.
Cystometrogram:o Distinguishes b/w genuine stress incontinence and detrusor instabilityo Pressure sensors used to determine bladder and sphincter tone as bladder is filledo Observations made about:
Bladder filling capacity Presence/absence of a detrusor reflex Patient’s ability to control or inhibit the strong desire to void
Uroflowmetryo Measures rate of flow through urethrao Patient asked to spontaneously void whilst sitting on a chairo Particularly useful in patients complaining of:
Hesitancy Incomplete bladder emptying Poor stream Urinary retention
Urethroscopy/Urethrocystometry
Ability to fit a ring pessary Vaginal pessaries:
o Mechanical support for lost structural integrity of pelviso Indicated if surgery is C/Io Placed in the vagina, positioned like a diaphragmo Need regular follow up to avoid trauma and necrosiso No sex whilst in position
Common Gynaecological cancers
Ability to relate to the patient with cancer
See Greg Gard’s lecture (Monday wk 5) for facts Be sensitive, listen to the patient, tell them about the problem, options etc…. (touchy, feely!)
Explanation of further investigation
Ability to explain techniques and principles of:o Infertility investigation
90 % of young couples conceive within 1 yr Infertility Causes (some couples have multiple causes):
o Anovulation: 20%o Male factors: 25-40%
Endocrine: Hypothalamic dysfunction, pituitary failure, hyperprolactinaemia,
exogenous androgens, thyroid disease, adrenal hyperplasia Abnormal Spermatogenesis:
Mumps orchitis, chemical/radiation/heat, varicocele, cryptorchidism) Abnormal motility:
Varicocele, antisperm antibodies, kartagener’s syndrome, idiopathic Sexual dysfunction:
Retrograde ejaculation, Impotence, decreased libidoo Uterine-tubal factors: (30%)
Uterine abnormalities Congenital, submucosal leiomyoma, intrauterine synechiae
Tubal occlusion PID, Tubal ligation, endometriosis
o Peritoneal factors: (40%) Endometriosis, pelvic adhesions
o Cervix abnormalities (10%) DES exposure, stenosis, surgery, cervitis, hostile mucus, mulleriuan duct
abnormality
History:o Male
Puberty Previous pregnancies fathered Environmental exposures Illness:
STI’s Mumps orchitis
Surgery: Hernia repair, orchidopexy, bladder neck surgery, prostate Trauma to genitals Occupation: is he home when ovulation occurs
o Female: Menstrual history Endometriosis: (Maybe Pain, Dyspareunia, Abnormal bleeding) Adhesions: (maybe pain) STI’s Contraception Previous pregnancies Pelvic infections Abdominal surgery
o Both: Technique, frequency, timing Feelings about infertility Previous investigation
Physical Examinationo Male:
Endocrine signs Signs of testosterone deficiency Varicocele Identify urethral meatus / penile abnormalities Testicular size (Normal = 3.5-5.5 x 2.1-3.2)
o Female: General health Hirsuitism Endocrine Sexual development Abdominal/pelvic exam
Investigations:o Ovulation:
Track menstrual cycle Measure basal body temperature (rise mid cycle) Cervical mucus: ‘raw egg white’ at mid cycle Midluteal surge serum progesterone (day 21 rise, 7 days pre
menstruation) LH surge (at ovulation, midcycle) US: visulaise follicle development or change to secretory
endometrium Endometrial biopsy: adequate gland and stromal development Premenopausal/ovulatory symptoms Progestin challenge:
o 5-10/7 progestin administration, then stopped: should bleedo demonstrates endometrium’s response to progesterone
Endocrine evaluation:o FSH, LH, prolactin, TFT’s, thyroid antibodieso Cushings: Serum testosterone, DHEAS, 17-
hydroxyprogesterone, 24hr urinary cortisol, overnight dexamethasone suppression test
o Intracranial pathology: MRI or CTo Male:
Semen analysis: Volume (mean 2.75ml) Count (>20 million) Morphology (>60% normal) Motility (>40%) Ph WCC Antibodies Infection If abnormal:
o Endocrine evaluation: TFT’s, serum testosterone, prolactin, FSH
Post coital test Less common Normal= large no. sperm seen in thin acellular mucus.
o Uterine-tubal Pelvic ultrasound Hysterosapingogram Sonohystogram
Hysteroscopy Laparoscopy
o Peritoneal causes: Laparoscopy
o Cervical causes: Post coital test
o Cancer treatments Vulval:
o Leukoplakia Topical corticosteroids
S/E: mucosal thinning, absorption PUVA, methotrexate, cyclosporin
o VIN seen with 5% acetic acid (6% go onto cancer, linked with HPV) Wide local excision or laser ablation
o Carcinoma (95% are squamous, rare, occur in elderly mainly) Stage 1 and 2 (<2cm, no nodes)
‘triple incision’ or radical vulvectomy + wide excision + inguinal nodes may need skin grafts
Cervical:o Regular Pap smears (2 yearly if normal)o Abnormal pap smear:
3 types: ASCUS: Atypical squamous cells of undetermined significance)
o Follow up pap smear in 6 months Squamous intraepithelial lesions Squamous cell carcinoma
If suggestive of CIN 1 (inflammatory cells, or mild atypia) Repeat pap smear in 6 months Or Colposcopy if 2nd repeat +ve
If suggestive on CIN 2/3 or cancer Colposcopy
o Abnormal tissue has characteristic blood vessels and stains white with acetic acid
o Punch biopsies taken for histologyo Doesn’t detect adenocarcinoma
o CIN 1 (mild dysplasia) Repeat pap smear 6 months 50% return to normal serial pap smears (6 monthly), colposcopy if continue to be abnormal. Takes 7 years on average to progress to cancer
o CIN 2/3 (moderate dysplasia) (98% curable) Small lesions confined to exocervix:
Cryotherapy Laser
Electrocautery (requires laser) Repeat colposcopy, papsmears
Endocervix Surgical excision of the transformation zone
o Cone biopsyo Loop (LEEP) Electrosurgical Excision procedureo Smear taken of tissue deep to that of biopsy and margins
checkedo INVASIVE DISEASE
95% SCC, 5% adenocarcinoma Stage 1 (tumors confined to cervix) – (80% 5 yr survival)
Consider cone biopsy to maintain fertility for microinvasive disease 1A1- simple hysterectomy 1A2 and 1B - radical hysterectomy
Stage 2 (local invasion beyond cervix but not beyond pelvic wall, involves vagina but not lower third)
TAH (60%- 5 yr survival) Stage 3 (Spread to pelvic wall and lower 1/3 of vagina)
Extensive radiotherapy and chemotherapy TAH (up to 50% survival?)
Stage 4 Palliation
Endometrial cancero Surgical stagingo TAHo BSOo Peritoneal washingo Pelvic aortic node samplingo Local or regional radiationo (stage 3 and 4 also: hormonal therapy and chemotherapy)
Ovariano 90% are epithelial tumors:
TAHBSO, omentectomy, debulking procedures, taxol and cisplatin based chemotherapy
o Germ cell tumors Removal of affected ovary, combination chemotherapy
o Colposcopy See above.
