Q

Urogenital prolapse

What is it and what does it encompass?

Risk factors
Symptoms
Management

A

A descent of one of the pelvic organs resulting in protrusion on the vaginal walls.
(Due to a loss of anatomical support)

Types
- Cystocele - Bladder sags into vagina
- Rectocele - Rectum sags into vagina
- Uterine prolapse - Uterus moves into vagina

RF
- Increasing age
- Multiparity (vaginal deliveries)
- Obesity

Sx
- Sensation of pressure, heaviness, dragging - usually worse at end of day
- Incontinence, frequency, urgency, (urinary retention)

Management
- If asymptomatic/mild prolapse - no treatment needed
- Conservative - weight loss, pelvic floor muscle exercises
- Mechanical support e.g. ring pessary (artificial pelvic floor)

If severe - surgery
Cystocele - anterior colporrhaphy
Uterine prolapse - hysterectomy
Rectocele - posterior colporrhaphy

Q

Asherman’s syndrome

Pathology
RF
Sx
Dx
Tx

A

An acquired condition where scar tissue (adhesions) form inside the uterus - leading to less space in the uterus (and adherence of the walls)

RF - previous surgery of uterus, pelvic infections, cancer treatment

Previous surgeries: hysteroscopy, dilation and curettage, C-section

Sx
- Pelvic pain/cramping
- Amenorrhea/hypomenorrhea

A

The growth of ectopic endometrial tissue outside of the uterine cavity. - highly oestrogen dependent process

More common in nulliparous women.

Pathology
It can occur throughout the pelvis (commonly on/behind ovaries and the pelvic peritoneum. Also - vagina, bladder, rectum). It causes inflammation, with progressive fibroids and adhesions (that can render the pelvic organs immobile in its most severe form)

Sx
- Chronic pelvic pain
- Dysmenorrhoea (pain starts a few days before bleeding)
- Painful intercourse (dyspareunia)
- Fertility issues/subfertility
- Non gynaecological - dysuria, urgency, haematuria, dyschezia (painful bowel movements)

Rf - early menarche, PCOS, pre-menopausal group, first trimester of pregnancy Benign ovarian cysts - very common Complex (e.g. multi-loculated) ovarian cysts should be biopsied to exclude malignancy. Pathology Follicular cyst - Most common type of ovarian cyst - Due to non-rupture of the dominant follicle Corpus luteum cyst - If corpus luteum doesn't break down (when pregnancy does not occur) - Can present with intraperitoneal bleeding (Benign germ cell tumour - Dermoid cyst/teratoma --> most common in women <30 years (may contain, skin, hair, teeth)) Vague symptoms - Palpable adnexal mass (near the fallopian tube and ovaries) - Abdominal distension/bloating - Early satiety - Pelvic pain

32
Baby blues Symptoms
A short term dip in mood after delivering a baby. (Seen in 6-70% of women) It usually starts 2-7 days after giving birth and goes away 1-2 weeks after. (Could be due to changes in hormone levels - oestrogen dropping by more than 100 times. or due to parental stress) Sx - Mood swings - Irritable, anxious, restless - Feeling guilty that you're not happy - Fatigue - Changes to appetite (Usually emotional support, counselling and patience can help a new mum get through this period)

36
Ectopic pregnancy Rf Pathology Sx
Implantation of a fertilised ovum outside the uterus Rf: (Anything that can slow the ovum's passage to the uterus) - Pelvic inflammatory disease (damages the tubes), endometriosis, progesterone only pill, IVF, IUD use, smoking, STI Pathology - Most common site - ampulla of fallopian tube - Most dangerous in the isthmus as it increases the risk of rupture - Should the ectopic pregnancy rupture, the women may present in shock from blood loss (and referred pain from intraperitoneal blood) Sx - history of 6-8 weeks amenorrhoea who presents with lower abdominal pain and later develops dark vaginal bleeding. - Constant lower abdominal pain (due to tubal spasm - mostly unilateral) - Dizziness or syncope - Peritoneal bleeding can cause shoulder pain. (Pregnancy related symptoms like breast tenderness)
37
Miscarriage (spontaneous abortion) Rf Pathology Sx
Rf - Advanced maternal age (>35), history of miscarriage, smoking, alcohol, obesity, diabetes, thyroid problems, previous cervical cone biopsy. Pathology - Highest incidence in the first trimester (first 12 weeks) - Chromosomal abnormalities account for 50% of early miscarriages Sx - Vaginal bleeding with/without clots - Suprapubic pain (cramping may signify the process of expulsion of the fetus) (post coital bleeding)
38
Types of miscarriage
1) Threatened miscarriage - Painless vaginal bleeding (usually within the first 12 weeks) 2) Missed/delayed miscarriage - A gestational sac containing a dead fetus before 20 weeks without the symptoms of expulsion (light vaginal bleeding/discharge -Symptoms of pregnancy disappear) 3) Inevitable miscarriage - Heavy bleeding with clots and pain - Cervical os is open 4) Incomplete miscarriage - Not all products of conception have been expelled - Pain and vaginal bleeding - Cervical os is open
39
Causes of recurrent miscarriage
3 or more consecutive spontaneous abortions. Causes - Antiphospholipid syndrome - Poorly controlled diabetes/thyroid disorders - PCOS - Parental chromosomal abnormalities - Smoking
40
Termination of pregnancy Law regarding it What must be given to women who are having an abortion after 10 weeks of abortion? How is the abortion induced? What is required for monitoring after?
(Abortion) - 2 registered medical practitioners must sign a legal document. Abortion can only be performed within 24 weeks of gestation. Anti-D prophylaxis should be given to women are rhesus D negative and are having an abortion after 10 weeks gestation --> to prevent the mother's own body from producing it's own natural anti-D prophylaxis (which can affect future pregnancies) Medical abortion - Mifepristone (anti-progestogen) followed by misoprostol 48 hours later - to stimulate uterine contractions (this mimicks a miscarriage) Multi-level pregnancy test (detecting hCG level) - A pregnancy test is required after 2 weeks to confirm the pregnancy has ended. Surgical - Transcervical proecdures e.g. vaccum aspiration, dilatation and evacuation --> Following this, an intrauterine contraceptive can be inserted immediately after evacuation.
41
Multiple pregnancy RF Types of multiple pregnancies
Twins occur 1 in 100 pregnancies, triplets 1 in 10000 pregnancies. Rf of dizygotic twins: Previous twins, IVF, induced ovulation, multigravida, increasing maternal age, Afro-carribean. Types of multiple pregnancies 1) Dizygotic twins (most common twin type - 80%) - Non identical - Fertilisation of 2 different oocytes by 2 different sperm (Triplets same cause) 2) Monozygotic twins - Identical - A single ovum that (mitotically) divided into 2 embryos --> Monoamniotic monozygotic twins share the same placenta and amniotic sac. They are associated with: increased spontaneous miscarriage, perinatal mortality rate, increased malformations, prematurity (Most diagnosed only at ultrasound. (Uterus may be larger and palpable before 12 weeks)
42
Complications of multiple pregnancies Maternal Antenatal Monochorionicty
Maternal complications - Gestational diabetes - Pre-eclampsia - Anaemia (due to increased blood volume - dilutional effect + increased demand for folic acid and iron) Antenatal complications (for twins. Triplets will be worse odds) - Greater mortality (6x) - Long term handicap (5x) (Rf: pre term delivery, intrauterine growth restriction, monochorionicity) Monochorionicity 1) Monochorionic, diamniotic - shared placenta but separate amnions --> Leads to twin-twin transfusion syndrome (TTTS) - unequal blood distribution due to abnormal vascular anastomoses with the shared placenta --> One twin (the donor) develops anaemia, IUGR and oligohydramnios whilst the other may develop polycythaemia, polyhydramnios. (TX: laser ablation) - poor prognosis
43
Obesity in pregnancy Maternal risks Fetal risks
Defined as BMI >30. Maternal risks - Miscarriage - Venous thromboembolism - Gestational diabetes - Pre-eclampsia - Postpartum haemorrhage - Wound infections (Higher C-section rate) Fetal risks - Prematurity - Macrosomia - Stillbirth - Increased risk of developing obesity and metabolic disorders in childhood - Neonatal death (within the first 28 days of birth)
44
Gestational diabetes Rf Pathology Fetal complications Maternal complicationsg
Rf - Obese, previous gestational diabetes, previous macrosomic baby, first degree relative with diabetes, unexplained still birth in previous pregnancy, south asian (usually asymptomatic) Pathology - Glucose tolerance decreases in pregnancy Fetal complications - Macrosomia - Raised fetal blood glucose levels induce fetal hyperinsulinemia --> increased fetal fat deposition and excessive growth - POLYHYDRAMNIOS - Raised blood glucose --> increased glucose excretion into the urine --> water follows glucose --> thus producing more urine than usual - Congenital abnormalities - neural tube or cardiac defects Maternal complications - Hypoglycemia may result from treatment - UTI infection - Pre-eclampsia - Pre-existing ischaemic heart disease can worsen
45
What are the 3 types of hypertension in pregnancy? What is the definition of hypertension in pregnancy (gestational hypertension)? Management for gestational hypertension
(Blood pressure falls in the first 24 weeks of pregnancy) Rf of gestational hypertension: nulliparous, maternal age >35, black, obesity. 3 types of hypertension 1) Pre-existing hypertension - A history of hypertension before pregnancy/before 20 weeks gestation - No proteinuria/oedema - If a pregnant woman is taking ACE inhibitor or ARB for hypertension, stop this immediately and start labetolol 2) Gestational hypertension - Blood pressure > 140/90 occurring after 20 weeks gestation in a previously normotensive patient without the presence of proteinuria. - No proteinuria, no oedema - Resolves following birth (after 1 month) - increased risk of pre-eclampsia or hypertension later in life (also an increase in systolic >30 or diastolic >15) MANAGEMENT - Regular monitoring of BP and urinalysis during the pregnancy to exclude pre-eclampsia 1st line - Oral labetalol 2nd line/asthmatic - oral nifedipine (hydralazine) 3) Pre-eclampsia - Pregnancy induced hypertension associated with proteinuria - Possible oedema
46
Pre-eclampsia Definintion RF Pathology Sx
New onset BP >140/90 after 20 weeks of pregnancy AND proteinuria/other organ involvement e.g. renal insufficiency (creatinine > 90), liver, neurological, uteroplacental dysfunction. Triad of: new-onset hypertension, proteinuria, oedema Pre-eclampsia is thought to be caused by abnormal trophoblast invasion and failure of spiral artery remodelling --> and so remains narrow and high resistance --> hypoxic placenta --> oxidatively stressed placenta over secretes proteins --> resulting in manifestations of the disease RF: hypertension in previous pregnancy, CKD, autoimmune diseases, diabetes, maternal age >40, obesity, family history, nulliparity Sx - Hypertension (usually >160/110) - Proteinuria - Headache - Visual disturbance - Papilloedema - Oedema - Abdominal pain (RUQ/epigastric) - Hyperreflexia - Low platelets, abnormal liver enzymes or HELLP syndrome

HELLP syndrome Pathology Symptoms Investigation Treatment
A severe form of pre-eclampsia that can develop in the late stages of pregnancy A subtype of severe pre-eclampsia characterised by: Haemolysis - Dark urine, raised lactic dehydrogenase, anaemia Elevated Liver enzymes - epigastric pain, liver failure, abnormal clotting Low platelets - normally self limiting Sx - N+V - RUQ pain - Lethargy (Most have hypertension and proteinuria) Dx - Bloods: Elevated liver enzymes and low platelet count - Peripheral blood smear - Haemolysis --> Schistocytes Tx - Deliver the baby - IV dexamethasone is administered before and after delivery - Magnesium sulphate for seizure prophylaxis If haematocrit <20% - Blood transfusion If platelet count low - platelet transfusion
48
Eclampsia Definition Treatment
The development of seizures in association with pre-eclampsia - Pregnancy induced hypertension after 20 weeks gestation with proteinuria Tx First line - magnesium sulphate (for prevention and treatment of seizures) - should be continued for 24 hours after delivery/last seizure Important things to monitor during treatment: - Oxygen saturations - Urine output - Reflexes - Respiratory rate (if respiratory depression occurs due to magnesium sulphate, GIVE CALCIUM GLUCONATE)

When are pregnant women screened for anaemia Pathology What are the cut off's to determine if a woman needs iron therapy? What is the management
Screened at booking visit and at 28 weeks Pathology The 40% increase in blood volume during pregnancy is greater than the increase in red cell mass. Iron supplementation is necessary to prevent iron-deficiency anaemia. Folic acid and vitamin B12 are also necessary supplements. First trimester - <110g/L Second/third trimester - <105g/L Post partum <100g/L Management - Oral ferrous sulphate/ferrous fumarate --> Continued 3 months after iron deficiency is corrected.how

How are the 3 trimesters of pregnancy split in humans?
1st trimester - Conception to 12 weeks 2nd trimester - 13 to 27 weeks 3rd trimester - 28 to 40 weeks
51
Venous thromboembolism in pregnancy
Rf - Previous VTE (high risk), >35 years, smoker, varicose veins, immobility, family history, multiple pregnancy, IVF pregnancy, >30 BMI For women with previous VTE or high risk thrombophilia - LMWH throughout antenatal period For women at risk of VTE due to hospitalisation, surgery, co-morbidities --> LMWH should be started and continued until 6 weeks postnatal. Tx In pregnancy - LMWH is the treatment of choice for VTE prophylaxis (DOAC and warfarin is avoided in pregnancy)
52
Chlamydia and gonorrhoea in pregnancy What is the treatment
Most women are asymptomatic Best known as causes of pelvic inflammatory disease and subfertility. Can be associated with preterm labour Tx Chlamydia - Azithromycin/erythromycin (Tetracyclines cause fetal tooth discolouration) Gonorrhoea - Ceftriaxone
53
Bacterial vaginosis Pathology Sx Complications in pregnancy
An overgrowth of predominantly anaerobic organisms e.g. Gardnerella vaginalis --> leads to raised vaginal pH Not sexually transmitted but seen almost only in sexually active women Sx - Asymptomatic in 50% - Vaginal discharge that is offensive Preterm labour, low birth weight and late miscarriages are more common
54
Chlamydia and gonorrhoea symptoms, investigation and treatment
Chlamydia trachomatis - Most prevalent STI in UK - Mostly asymptomatic --> possibly vaginal discharge and bleeding and dysuria - Dx: Vulvovaginal swab and NAAT (in women).... if positive then culture (National screening programme for ages 15-24) - Tx: First line: Doxycycline 7 days, if pregnant - azithromycin/erythromycin Neisseria gonorrhoea - Sx: Vaginal discharge - Dx: Dx: Vulvovaginal swab and NAAT (in women)... Culture Tx: IM ceftriaxone Complication: disseminated gonococcal infection - triad: tenosynovitis, migratory polyarthritis, dermatitis
55
Group B streptococcus (GBS) Rf Symptoms in a baby if spread to them? Indication for treatment and what treatment to give?
The most common cause of early-onset severe infection in the neonatal period. (about 20-40% of mothers have group b strep in their bowel flora) --> Infants can be exposed to GBA during labour. Rf- prematurity, prolonged rupture of the membranes/prolonged labour, previous sibling GBS infection, maternal pyrexia (Symptoms in a baby - Floppy - Respiratory distress - Not feeding well - Unusually/slow/fast heart rate - Changes in skin colour) Dx Women who've had GBS detected in a previous pregnancy should either be given intrapartum antibiotic prophylaxis (BENZYLPENCILLIN) (or testing in late pregnancy followed by antibiotics if positive) Women with pyrexia during labour should also be given intrapartum antibiotic prophylaxis
56
Syphilis in pregnancy
(Rare in pregnancy women) Disease in pregnancy can cause: miscarriage, severe congenital disease or stillbirth. Congenital syphilis: saddle nose, deafness, rhagades (linear scars at the angle of the mouth) Dx and Tx Screen the mother - Venereal Disease Research Laboratory (VDRL) test If the mother has syphilis, Benzylpenicillin should be given to treat the mother (at least 4 weeks of treatment)
57
Puerperal infection/pyrexia Definition Causes Treatment
A temperature of >38 degrees in the first 6 weeks following delivery Causes (mainly infection) - Endometritis - UTI - Wound infection - Mastitis - DVT Treated with sepsis 6 Give: Antibiotics, fluids, oxygen Take: Urine output, blood cultures, lactate Antibiotics - for endometritis - clindamycin and gentamicin
58
Trichomonas vaginalis Sx Dx Tx
A protozoa (STI) Sx - Offensive yellow/green discharge - Dysuria - Dyspareunia - Vulval irritation - Strawberry cervix Investigation - Wet film microscopy - motile trophozoites - NAAT Tx - Oral metronidazole (Can cause premature baby/low birth weight)
59
How to manage suspected UTI in pregnancy?
Arrange urgent hospital admission if: - Severe systemic symptoms e.g pyelonephritis or sepsis Arrange referral if - Recurrent UTI diagnosed during pregnancy - Catheter associated UTI - Atypical organism on culture If first presentation of uncomplicated UTI - Simple analgesia (paracetamol/NSAIDS) - Prescribe antibiotic - nitrofurantoin (avoid in 3rd trimester) 2nd line - cefalexin Associated with increased risk of pre term delivery and intrauterine growth restriction
60
Chickenpox (varicella zoster) exposure in pregnancy How does chickenpox affect the mother? How does chickenpox affect the fetus? Sx? Dx? Tx for 1) chicken pox exposure and 2) chicken pox during pregnancy?
Risk to the mother - 5 times greater risk of pneumonitis Fetal varicella syndrome (mostly is exposure to varicella before 28 weeks gestation) Sx: Skin scarring, eye defects (micropthalmia), microcephaly, learning disabilities May be fatal to the newborn child if mother develops rash close to the birth. Dx - Urgently check if mother has varicella antibodies Tx - Oral aciclovir 7-14 days after exposure for post-exposure prophylaxis If the pregnant women develops chicken pox --> immediate oral aciclovir - within 24 hours onset of rash.
61
Oligohydramnios Pathophysiology Causes Sx Dx Tx
An abnormally low volume of amniotic fluid surrounding the fetus during pregnancy. Pathophysiology - Amniotic fluid is initially produced by the mother which is then replaced by fetal urine. Volume peaks at 38 weeks and decreases near birth --> it's function is to protect the fetus and aid organ development. Causes (either due to increased fluid loss or decreased fluid production) - Rupture of membranes - most common - Renal agenesis + pulmonary hypoplasia (potter sequence) - Decreased fluid production (Intrauterine growth restriction) - Pre-eclampsia - Maternal comorbidities e.g. hypertension (Sx - fetal parts would be easier to palpate, uterus may appear small for dates, if there is rupture of membranes - there may be fluid leaking from the vagina) Dx - Ultrasound - A maximum vertical pocket <2cm) Tx - Serial monitoring and possible therapeutic amnioinfusion - Labour induction between 36-38 weeks.
62
Oligohydramnios complications
(poorer prognosis if diagnosed <24 weeks) - Limb deformities - Pulmonary hypoplasia - Increased risk of chorioamnionitis - Umbilical cord compression - Meconium aspiration
63
Polyhydramnios Causes Sx Dx Tx
Abnormally large volume of amniotic fluid. Mechanisms that are involved 1) Fetal swallowing - Atresia of the GI tract, fetal hypoxia, neuromuscular disorders can decrease fetal swallowing volume 2) Fetal urination - Anaemia and gestational diabetes can cause increased urination due to increased cardiac output Causes - Mostly idiopathic - Oeseophageal/duodenal atresia - Cardiovascular defects - Renal defects - Genetic disorders - Trisomy 21, 18 and 13 - Gestational diabetes - Fetal anaemia (heart works harder to compensate for the reduced oxygen delivery) - Multiple pregnancy Sx - Uterus is large for its date - Fetal parts are difficult to palpate - Picked up on ultrasound Dx Ultrasound - A maximum vertical pocket >8cm If fetal anemia/hydrops fetalis is suspected - Tx Mild polyhydramnios - monitored and treated conservatively Severe polyhydramnios --> Amnioreduction (needle aspiration) Indomethacin can also be given --> reduces renal blood flow and thus fetal urination (however there is a risk of ductus arteriosus constriction)
64
Polyhydramnios complications
- Increased risk of preterm labour - Premature rupture of membranes - Placental abruption - Postpartum haemorrhage - Increased risk of UTI due to increased pressure on urinary tract
65
Causes of failure to progress Criteria for failure to progress Investigation for monitoring progress of labour
Failure to progress - First stage - less than 2cm cervical dilation in 4 hours - Second stage - Taking more than 1 hour in a multiparous woman and more than 2 hours in a nulliparous woman (pushing stage) - Third stage (delivery of placenta) - Longer than 30 mins with active management (oxytocin infusion/cord traction) or longer than 60 mins with physiological management 3 causes: Power - Force of uterine contractions (insufficient uterine action- most common cause) Passenger - SIZE (the larger the more difficult), PRESENTATION (cephalic, shoulder, breech), POSITION (straight down or side to side) Passage - Shape and size of pelvis --> Cephalopelvic disproportion (baby's head doesn't fit through the opening of pelvis) Dx A partogram is used to measure the progress of labour (cervical dilation, maternal BP, pulse, fetal heart rate, etc) --> Dilation of cervix is plotted against duration of labour and if it is progressing too slowly and it crosses the: - ALERT line --> Amniotomy (artificial rupture of the membranes) - ACTION line --> care is escalated to senior decision (perhaps C-section)
66
Treatment for failure to progress
Power - If too weak, give OXYTOCIN infusion to stimulate uterus. Passenger - Changing positions (rotates the baby) Passage - INSTRUMENTAL delivery, C-SECTION, episiotomy (surgical incision to widen the vaginal opening) AMNIOTOMY if cervical dilation is progressing too slowly (Usually prostaglandin first, then amniotomy then oxytocin infusion) Other methods - Membrane sweep - inserting a finger into the vagina to stimulate the cervix - Prostaglandin E2 --> stimulates cervix and uterus to cause onset of labour
67
Cephalopelvic disproportion RF Causes Treatment Complication
RF - Post term birth, family history of large babies, maternal gestational diabetes, obese parents Causes - Large babies - Bony growths of the pelvis - Petite body size - pelvic opening is too small Tx - Delivery either by instrumental delivery or C-section Complications - Shoulder dystocia - Vaginal tears - Postpartum haemorrhage
68
Possible presentations of a baby
Cephalic - Head first (normal) (Transverse - lying side to side) Shoulder - Shoulder first Breech - Complete breech --> Hips and knees flexed - Frank breech --> Hips flexed and knees extended (butt first - most common breech) - Footling breech --> Foot hanging out the cervix
69
Risk factors for breech presentation Tx after 36 weeks
- Uterine malformations - Fibroids (non cancerous growths in the uterus) - Placenta praevia (placenta partially/completely covers the opening of the uterus) - Poly/oligohydramnios - Prematurity Cord prolapse is more common in breech presentation Tx At 36/37 weeks if still breech- External cephalic version (applying pressure on the mother's abdomen) - CI in multiple pregnancy or ruptured membranes (or if C-section is required) If baby is still in breech --> Planned C-section (or vaginal delivery)
70
Shoulder dystocia Pathology Rf Tx Complications
A complication of cephalic delivery where the anterior fetal shoulder becomes stuck behind the pubic symphysis after the head has been delivered --> OBSTETRIC EMERGENCY (Can cause maternal and fetal morbidity/mortality) RF - Fetal macrosomia, high maternal BMI, maternal DM, prolonged labour Tx - Need assistance from senior doctors/paediatricians/anaesthetics - McRobert's manoeuver - flexion and abduction of the maternal hips (posterior pelvic tilt) Episotomy is sometimes used to prevent perineal tears and to allow better access for internal manoeuvers e.g. Rubin/wood screw - reaching into the vagina and rotating the baby Zavenelli - can cause significant maternal morbidity (pushing the baby back into the vagina to be delivered by C-section) (Suprapubic pressure to help shoulders move under the pubic symphysis) Maternal - Perineal tear - Postpartum haemorrhage Fetal - Brachial plexus injury, erb's palsy - Fetal hypoxia and death
71
Uterine rupture Rf Symptoms Treatment Complication
A complication of labour where the muscle layer of the uterus (myometrium) ruptures. Rf - Previous C-section, previous uterine surgery, high parity, increased BMI, increased age, induction of labour, use of oxytocin to stimulate contraction Incomplete rupture - with serosa (surrounding the uterus) intact Complete rupture - Serosa and myometrium ruptured - releasing contents of the uterus into the peritoneal cavity. (possibly the baby released as well) Sx - Acutely unwell mother and abnormal CTG - May occur in induction/use of oxytocin --> Abdominal pain, CEASING OF UTERINE CONTRACTIONS, vaginal bleeding, tachycardia and hypotension Tx - Emergency C-section - Possible hysterectomy (Maternal resus with IV fluids and blood transfusion) Complication Can cause massive internal haemorrhage in the mother and acute fetal hypoxia
72
Premature labour Definition Risk factors Investigation
Birth occurring before 37 weeks gestation. (Would present with painful contractions and cervical dilation) Rf - Previous premature labour, previous induced abortion, maternal infections, multiple pregnancy, short cervix length, low socioeconomic status, maternal diabetes/thyroid disease, fibroids, polyhydramnios Dx - Speculum examination - assessing dilation of cervix - Fetal fibronectin assay (swab) - elevated means high risk of preterm labour - Transvaginal ultrasound - measure cervical length - Cardiotocography - monitoring both fetus and mother
73
Premature labour Prophylaxis Treatment
Prophylaxis 1) Cervical cerclage - inserting sutures into the cervix to strengthen it and keep it closed 2) Progesterone supplement - Maintains pregnancy and prevent labour by decreasing activity of the myometrium and prevents remodelling of the cervix in preparation for delivery. Treatment 1) Tocolysis with nifedipine 2) Corticosteroids - IM betamethasone - reduce perinatal morbidity by promoting pulmonary maturity (given before 35 weeks gestation) (Magnesium sulphate can be given before 34 weeks gestation to protect baby's brain and reduce risk of cerebral palsy) - Cord clamping can also be delayed to increase circulating blood flow in the baby at birth.
74
What medications are used for abortion? Dive into specific - how long along the pregnancy, what other uses do they have?
Mifepristone (anti progesterone) and Misoprostol (Prostaglandin E2) - Used in abortion for pregnancies less than 10 weeks long - Used in intrauterine fetal death (to induce labour)
75
What is the main complication of using prostaglandin E2 in induction of labour? Complication Treatment
Uterine hyperstimulation - Contraction of the uterus is prolonged and more frequent, causing fetal distress and compromise Contractions last more than 2 mins/ more than 5 contractions in 10 mins Can lead to: fetal hypoxia, uterine rupture and emergency c-section Management - Remove vaginal prostaglandin/stop oxytocin infusion - Tocolysis with terbutaline (terbutaline is for acute) (tocolysis in premature labour - longer term --> nifedipine)
76
Umbilical cord prolapse RF Dx Tx
It involves the umbilical cord descending ahead of the presenting part of the fetus. --> It can lead to compression of the cord which can cause fetal hypoxia and eventual death. Rf - Prematurity, multiparity, abnormal presentations e.g. transverse lie, breech, polyhydramnios, multiple pregnancy 50% of cord prolapses occur during amniotomy Dx - This should be suspected when there are signs of fetal hypoxia on CTG or when the cord is visible beyond the introitus. Tx - The presenting part of the fetus may be pushed back into the uterus to avoid compression - If cord is visible past introitus, keep it warm and moist to avoid vasospasm - Mother should be in the knee-chest position (on all 4s) - Tocolytics are used to reduce contractions (terbutaline) (filling the bladder with saline to elevate the presenting part may help) - C SECTION IS USUALLY FIRST LINE DELIVERY
77
What are the methods of instrumental delivery? When is it needed? (indication) Risks to the mother Risks to the fetus
1) Ventouse suction cup delivery 2) Forceps delivery (A single dose of co-amoxiclav is recommended after instrumental delivery to reduce risk of maternal infection) Indications - Failure to progress - Fetal distress - Maternal exhaustion - Needing to control the head in various positions Maternal risks - Perineal tears - Postpartum haemorrhage - Incontinence of the bladder/bowel - injury to the anal sphincter - Nerve injury (femoral) - weakness of knee extension - anterior thigh - Nerve injury (obturator) - weakness of hip abduction and numbness of medial thigh Fetal risks - Cephalohaematoma - ventouse suction delivery - Facial nerve palsy - forceps delivery
78
2 causes of obstructed labour
- Cephalopelvic disproportion - Malpresentation (breech, shoulder)
79
Premature rupture of membranes Dx Tx
Rupture of the amniotic sac before the onset of true labour contractions (smoking, infection, placental issues could be risk factors) Dx: Speculum examination - amniotic fluid pooling in vagina - Insulin like growth factor 1 binding protein elevated on vaginal swab (or placental alpha microglobin 1) Prophylactic erythromycin for CHORIOAMNIONITIS Tx if >34 weeks gestation may induce labour If <34 weeks gestation - Corticosteroids (betamethasone), magnesium sulphate, tocolysis
