This document discusses medical termination of pregnancy in India. It provides definitions and describes the Medical Termination of Pregnancy Act passed in 1971 that legalized abortion in India. The key methods of abortion discussed include medical methods using medications like mifepristone and misoprostol as well as surgical procedures for terminating pregnancies in the first and second trimesters. Surgical procedures described include vacuum aspiration and dilation and evacuation.
the deliberate use of artificial methods or other techniques to prevent pregnancy as a consequence of sexual intercourse. The major forms of artificial contraception are barrier methods, of which the most common is the condom; the contraceptive pill, which contains synthetic sex hormones that prevent ovulation in the female; intrauterine devices, such as the coil, which prevent the fertilized ovum from implanting in the uterus; and male or female sterilization.

EMERGENCY CONTRACEPTION & RECENT ADVANCEMENT IN CONTRACEPTION
Introduction
Emergency contraception (EC) is a method of contraception used as an emergency procedure before menstruation is missed, to prevent pregnancy following unprotected intercourse or expected failure of contraception.
Cont..
Emergency contraception is any method of contraception which is used after intercourse and before the potential time of implantation. This nomenclature, advocated by WHO lately and accepted by international Medical Advisory Panel and others recently.
Alternative terms: Postcoital contraception- still commonly used and 'morning after' contraception
Emergency contraception is not true contraception but rightly called interception. Interceptive - agents that do not interfere with fertilization but act on blastocyst before or soon after missing periods.
Emergency contraception is a backup plan. It cannot be used as an ongoing method of contraception because:
i) relatively high failure rates
ii) High incidence of irregular bleeding
INDIAN SCENARIO: NEED
India has the highest number of unsafe abortions in the world.
6,20,472 abortions reported in India in 2012, Two-third of them were unsafe
A woman dies every two hours due to unsafe abortion.
Widespread availability of EC can help reduce these abortions.
INDICATIONS
1. For aged couples who meet very infrequently.
2. Following single act of sexual exposure in young girls
3. When pregnancy is apprehended owing to rupture of condom, premature ejaculation in couples practising coitus interruptus etc.
4. In case of rape.
ADVANTAGES
Saves the couple from unwanted pregnancies
From unnecessary operative interferences for fear of pregnancy
From the agony of waiting for the next menstrual cycle.
Prevents adolescent pregnancies
Helps to reduce unsafe abortion
COMBINED ETHINYL ESTRADIOL AND LEVONORGESTREL (YUZPE METHOD)
Yuzpe method (Canadian Prof. Albert Yuzpe) consists of the oral administration of 2 doses of 0.1mg(100 µg) ethinyl estradiol (EE) and 0.5mg(500 µg) levonorgestrel 12 hours apart.
Failure rate- 0-2%
Ovral tablets (each containing 50 µg ethinyl estradiol and 250 µg levonorgestrel) are most commonly used to provide these doses.
Others- Noral, Ovidon
PROGESTIN-ONLY (LEVONORGESTREL)
In India- EC pill, Pill 72, unwanted
LNG-ONLY PILLS
2 doses of 0.75mg LNG pill to be taken orally 12 hours apart within 72hours of intercourse. OR Single dose of 1.5mg LNG pill to be taken within 72 hours of intercourse.
Trials have shown that a high proportion of pregnancies were averted even up to 5days (120hours). WHO recommends levonorgestrel for emergency contraceptive pill use.
Failure rate- 0-1%
Cont.
Side Effects:-
1. Nausea- in 50% using Yuzpe regimen & 20% for Levonorgestrel.
2. Vomiting - in 20% Yuzpe regimen & 5% using LNG-only pills.
If vomiting occurs within 2 hours of taking the pills - the dose should be repeated. In cases of severe vomiting - administer pills vaginally.
3. Irregular uterine bleedi
Abortions and Maternal Termination of Pregnancy pptMichael Kino
Abortion means spontaneous or induced expulsion of products of conception before the period of viability( 28 weeks).
In medical practice, the abortion occurs in 1st trimester, miscarriage in the 2nd trimester and premature labor in the 3rd trimester.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

2. INTRODUCTION
⚫Medical termination of pregnancy is refers as the
induction of abortion. The induction of abortion may
be legal & illegal. There are many countries in the
globe where the abortion is not yet legalised. In india
theabortion was legalised by “medical termination of
pregnancy Act ’’of 1971, &has been inforced in the
april 1972.
4. MEDICAL TERMINATION OF PREGNANCY
ACT 1971:-
⚫The Indian abortion laws falls under the Medical Termination of
Pregnancy (MTP) Act, which was enacted by the Indian
Parliament in the year 1971 with the intention of reducing the
incidence of illegal abortion and consequent maternal mortality
and morbidity. The MTP Act came into effect from 1 April 1972
and was amended in theyears 1975 and 2002.
⚫Recently, the Supreme Court permitted a rape survivor to
terminate herpregnancy at 24 weeks, which is beyond the
permissible 20 weeks limit prescribed under the Medical
Termination of Pregnancy Act, 1971
5. LEGAL ABORTION :-
- Termination is performed by the medical
practitioners(assisted in at least 25 mtp °ree in OBG) by
theact.
- Termination is doneat the placeapproved under theact.
- Termination done forcondition & within thegestation week
prescribed by theact.
- Theabortion has to be reported to thedirectorof health
service of thestate.
6. INDICATION
⚫Women whose physical and/or mental health were
endangered by the pregnancy
⚫Women facing the birth of a potentially handicapped or
malformed child
⚫Rape
⚫Pregnancies in unmarried girls under theageof eighteen
with theconsentof aguardian
⚫Pregnancies thatarea result of failure in sterilisation
7. FIRST TRIMESTER TERMINATION OF
PREGNANCY
METHODS OF FIRST TRIMESTER ABORTION:
Mifepristone (RU-486) and Misoprostol –
Mifepristone(200mg) an analog of progestin
(norethindrone) acts as an antagonist, blocking theeffect
of natural progesterone.
⚫Addition of low dose prostaglandins (800mg) (PGE1)
improves the efficiency of first trimester abortion. It is
effectiveupto 63 days and is highlysuccessful when used
within 49 days of gestation.
8. .
⚫Methotrexateand Misoprostol –
Methotrexate 50 mg/m2 IM (before 56 days of
gestation) followed by 7 days later misoprostol 800
μg vaginally is highlyeffective.
Misoprostol may have to be repeated after 24 hours
if it fails.
Methotrexateand misoprostol regimen is less
expensive but takes longer time than
Mifepristoneand Misoprostol.
9. .
SURGICAL METHODS OF FIRST TRIMESTER ABORTION:
⚫MENSTRUAL REGULATION:
It is the aspiration of the endometrial cavitywithin 14 days
of missed period in a woman with previous normal cycle.
Theoperation is done as an out patientoran office
procedure
It is donewith aseptic precautions.
After introducing the posteriorvaginal speculum, the
cervix is steadied with an Allis forceps.
10. .
.
Cervix may be gently dilated using 4 or 5 mm size dilators.
Thecannula is rotated, pushed in and out with gentle strokes.
Theoperatorshould examine the aspirated tissue by floating it in a
clear plastic dish overa light source.
This will help todetect failed abortion, molar pregnancyorectopic
pregnancy.
5–6 mm suction cannula (Karman’s) is then inserted and attached to
the 50 mL syringe forsuction.
The procedure is contraindicated in the presenceof pelvic
inflammation.
12. ⚫VACUUM ASPIRATION (MVA/EVA):
Done upto 12 weeks with minimal cervical dilatation
It is performed as an outpatient procedure using a plasticdisposable Karman’s
cannula (up to 12 mm size) and a 60 mL plastic (doublevalve) syringe.
It is quicker (15 minutes), effective (98–100%), less traumaticand saferthan
dilatation, evacuationand curettage.
The procedure may be manual vacuum aspiration (MVA) orelectricvacuum
aspiration (EVA).
Hand operated doublevalve plastic syringe isattached toacannula.
Thecannula is inserted transcervically into the uterus and thevacuum isactivated.
A negative pressure of 660 mm Hg iscreated.
Aspirationof the products of conception is done
13. DILATATION AND EVACUATION
(D+E) &( D+C) :
Theoperation consists of dilatation of the cervixand evacuation of
the product conception from the uterus
PROCEDURE :-
1. Vaginal examination is done to note the size and position of the
uterus and to note the state of cervix. USG should be performed
when there is any doubt about the gestational age.
2. Posteriorvaginal speculum is introduced and an assistant is
asked to hold it.
3. Theanterior lipof the cervix is to begrasped byan Allis forceps.
14. .
4. The cervix may have to be dilated with smaller size graduated metal
dilators up to one size less than that of the suction cannula. Feeling of
“snap” of the endocervix around the dilator is characteristic. Instead
laminaria tent 12 hours before (osmotic dilator) or misoprostol (PGE1) 400
μg given vaginally 3 hours prior to surgery produces effective dilatation.
5. Intravenous methargin 0.2 mg is administered.
6.The appropriate suction cannula is fitted to the suction apparatus by a
thick rubber or plastic tubing. The cannula is then introduced into the
uterus, the tip is to be placed in the middleof the uterinecavity.
7.The pressureof the suction is raised to 400–600 mm Hg. Thecannula
is moved up and down and rotated within the uterine cavity (360°) with
the pressure on. The suction bottle is inspected for the products of
conception and blood loss. The suction is regulated bya finger placed over
a holeat the baseof thecannula
15. The end point of suction is denoted by:
(a)No more material is being sucked out
(b)Gripping of the cannula by the
contracting smaller size uterus
(c)Appearance of bubbles in the cannulaor
in the transparent tubing.
8. After being satisfied that the uterus is
remaining firm, and there is minimal
vaginal bleeding, the patient is brought
down from the table afterplacing a sterile
vulval pad.
.
16. SECOND TRIMESTER TERMINATION OF
PREGNANCY
MEDICAL METHODS:
⚫PROSTAGLANDINS:
They act on the cervix and the uterus.
The PGE (dinoprostone, sulprostone, gemeprost, misoprostol) and
PGF (carboprost) analogues are commonly used
PGEs are preferred as they have more selective action on the
myometrium and less side effects.
17. 1. Misoprostol (PGE1 analogue)
o 400–800 μg of misoprostol givenvaginally at an interval of 3–4 hours is most
effectiveas the bioavailability is high.
o Alternatively, firstdose of 600 μg misoprostol givenvaginally, then 200 μg,
orallyevery 3 hours arealso found optimum.
o Recently 400 μg misoprostol is given sublinguallyevery 3 hours fora maximum
of fivedoses.
o This regimen has got 100% success in second trimesterabortion.
1. . Gemeprost (PGE1 analogue):
o 1 mg vaginal every 3–6 hours for fivedoses in 24 hours has gotabout 90%
success.
o The mean induction-abortion interval was 14–18 hours.
18. 1. Mifepristoneand prostaglandins:
o Mifepristone 200 mg oral, followed 36–48 hours later by misoprostol
o 800 μg vaginal; then misoprostol 400 μg oral every 3 hours for 4
doses is used.
o Success rateof abortion is 97% and median induction delivery
interval is 6.5 hours.
o Pretreatmentwith mifepristone reduces the induction— abortion
interval significantlycompared to use of misoprostol alone.
2. Prostaglandin F2 (carboprost):-
-250mg IM every 3 hours fora maximum 100 dose can be used
19. ,
⚫OXYTOCIN:
High dose oxytocin as a singleagentcan be used forsecond trimesterabortion.
It iseffective in 80% of cases.
It can be used with intravenous normal salinealong with any of the medications
used either intra-amniotic or extra-amniotic space in an attempt to augment
theabortion process.
MODE OF ACTION:
Myometrial oxytocin receptorconcentration increases maximum (100-200
fold) during labour.
Oxytocin acts through receptorand voltage mediated calcium channels to
initiate myometrial contractions.
20. SURGICAL METHODS:
It is difficult to terminate pregnancy in the second trimesterwith reasonable safetyas in
first trimester.
Between 13 and 15 weeks
⚫Dilatation and Evacuation in the midtrimester is less commonly done.
o Pregnancies at 13 to 14 menstrual weeks areevacuated.
o In all midtrimesterabortion cervical preparation must be used (WHO 1997) to
make the process easyand safe.
o Intracervical tent (Laminaria osmoticdilator), mifepristoneor misoprostol are used
as thecervical priming agents.
o The procedure may need to be performed under ultrasound guidance to reduce the
risk of complications.
o Simultaneous useof oxytocin infusion is useful.
21. Between 16 and 20 weeks:
---- Intra-amniotic
---- Extra-amniotic
⚫Intra-amniotic:
Intra-amniotic instillation of hypertonicsaline (20%) is less commonly
used now. It is instilled through theabdominal route.
Modeof action: There is liberation of prostaglandins following necrosis of
the amniotic epithelium and the decidua. This in turn excites uterine
contraction and results in theexpulsion of the fetus.
Procedure:
Preliminaryamniocentesis is done bya 15 cm 18 gauge needle.
Theamountof saline to be instilled is calculated as numberof weeks
of gestation multiplied by 10 mL.
Theamount is to be infused slowly at the rateof 10 mL/min.
22. ‘
⚫Extra-amniotic:
Extra-amniotic instillation of 0.1% ethacrydine lactate
done transcervically through a number 16 Foley‘s catheter
Thecatheter is passed up thecervical canal forabout 10 cm above the internal os
between the membranes and myometrium and the balloon is inflated (10 mL)
with saline.
It is removed after 4 hours. The success rate is similar to saline instillation but is
less hazardous.
Itcan be used in cases contraindicated forsaline instillation.
Stripping the membranes with liberation of prostaglandins from the decidua
and dilatation of the cervix by the catheter are some of the known factors for
initiationof theabortion.
