2) Haemodynamically unstable (<90/60mmHg) : immediate laparotomy
RARELY METHOTREXATE
Investigation in Ectopic
Inv: Beta HCG raised very much
USG ABDOMEN : EMPTY UTERUS ALTHOUGH POSITIVE PREGNANCY TEST WITH FREE FLUID IN POUCH OF DOUGLAS
REPEAT BETA HCG IN 48 HOURS IF USG FINDINGS ARE NOT
CONFIRMATIVE OF ECTOPIC PREGNANCY OR BETA HCG < 1500
NB : REQUIRES TO DO REPEAT BETA HCG IN 48 HOURS IF BETA HCG NOT >1500 , AND IF USG NOT CONCLUSIVE OF ECTOPIC PREGNANCY
Free fluid in Pouch of douglas - RUPTURED ECTOPIC
ECTOPIC PREGNANCY AND IUD
- Absolute Risk OF Ectopic Pregnancy : absolute meaning in term of getting pregnant at all
Without IUD»_space;> WITH IUD - Relative risk Of Ectopic Pregnancy : relative meaning in relation to
With IUD»_space;»Without IUD
RISK FACTOR FOR ECTOPIC PREGNACY
Highest in PID then IUD ….
MISCARRIAGES
COMPLETE : Massive bleeding PV + Passage of clots
TVS : Empty uterus no retained products of conception
INCOMPLETE: Bleeding PV + h/o passage of pdts of conception
TVS: Products of conception seen on the uterus but no viable fetus
INEVITABLE : Bleeding heavily + Open cervix
TVS: Fetus present +/- heart beat and miscaarriage is inevitable
MISSED : Pain / bleeding or both
TVS: Fetus without heart beat
THREATENED: Bleeding PV + fetal heart seen on usg
REPEAT URINE HCG AFTER 3 WEEKS TO CHECK FOR Retained products of placenta
Pelvic inflammatory disease
Young sexually active female
C.F : Fever+ Adnexal tenderness + Cervical Excitation, dyspareunia, vaginal purulent discharge.
Complications : Infertility, pelvic paina and ectopic pregnancy
Inv: Screening for Chlamydia and Gonorrhoea
Treatment of PID
Inpatient management of PID :
IV Ofloxacin + IV Metronidazole x 14 days
IV Ceftriaxone 2g AND Tab Doxy 100 mg BD + Tab Metronidazole 400 mg BD x 14 days
Outpatient management
IV Ceftriaxone 1g stat + Tab doxy 100 mg + Tab Metronidazole 400 mg BD x 14 days
OR
Tab Ofloxacin + Tab Metronidazole x 14 days
Management of PID in Pregnancy
Ceftriaxone or Cefuroxime safe in Pregnancy
Azithromycin safe in pregnancy
Doxy contraindicated in Pregnancy
CERVICITIS
Neisseria andChlamydia
C/F : IntermenstrualBleeding and Post Coital Bleeding
Investigations:
1) Vulvovaginal swab - NAAT to find neisseria and chlamydia- first line
AFTER NAAT POSITIVE
2) Endocervical swab and high vaginal swab sent in transport medium for gonorrhoea culture
Treatment of cervicitis
1) If chlamydia cervicitis - Doxycyline and azithromycin
2) if Neisseria cervicitis - ciprofloxacin or ceftriaxone
AMENNORHOEA
Cause
1. Hypothalamic amennorhoea : Low Gnrh , followed by Low LH and FSH
2. PCOS
3. Hyperprolactinemia
4. Premature ovarian failure : raised FH
5. Post Pill amennorhoea - after 6 months from stopping pill
Inv :Low LH, FSH, Oestrogen (negative feed back ) and raised prolactin
7.Anatomical
8.Pregnancy
ANEMIA IN PREGNANCY
<110g/L - First Trimester (upto 12 weeks )
<105g/L- Second (13w-27w ) and third Trimester (28w - 41w)
<100g/L-Post Partum
If anemia confirmed, Tab ferrous sulphate
Terminologies of menstruation
- Dysmenorraghia : Pain before or during menstruation
- Menorraghia : Heavy menstrual bleeding
- Amennorhea : Absent menstrual bleeding
DYSMENORRHOEA (Pain during menstruation)
Primary : no cause
Secondary : underlying pathology ( Endometriosis, Adenomyosis, PID )
Primary t/t:
* Mefenamic acid - first line
* Combined OCPS - Second line
* Mirena IUS - Third line
Secondary T/t : Treat underlying cause
APLA Syndrome
M/C for recurrent miscarriages Any women with one or more first trimester or second trimester miscarriages should be screened for Antiphospholipid antibodies before next pregnancy
T/T any pregnant women diagnosed with APLA should be given asprin 75 mg + Heparin
CTG
Normal : HR (110-160bpm ) ; Variability : 5-25 bpm ; Deceleration: none or early
Non reassuring: HR (100-109 OR 161-180 ); Variability : <5 ( 30 - 50 mins ) and >25 ( 15-25 mins) ;Deceleration : Late deceleration for less than 30mins.
Abnormal: HR( <100 or >180 bpm ) ; Variability : <5 (>50mins) or >25 (>25 mins) ; Deceleration: late deceleration for more than 30 mins OR acute bradycarida or single prolonged deceleration for more than 3 mins .
Management according to CTG
- Normal - Continue same tx
- Suspicious : 1 non reassuring feature
T/t: Conservative management :
1. Position to lateral decubitus
2. iv fluids
3. oxytocin or tocolytics
*Pathological : 2 non reassuring or 1 abnormal
T/t : Conservative first line
then expedite birth
Preeclampsia
GHTN ( New onset hypertension >140/90mmHg after 20 weeks of gestation ) + PROTEINURIA after 20 weeks of gestation
Proteinuria meaning
* 24 hour urine protein> 0.3g/24 hours ( least relied on theses days )
