3Introduction
- Coronaviruses are family of enveloped,
single-stranded RNA viruses mainly cause mild
symptoms like common cold - At the end of 2019, a novel coronavirus was
identified in a worker in Wuhan Sea food market
in the Hubei Province of China who had pneumonia. - It was observed that this strain exhibited
stronger virulence and quickly passed - from human to human
- In Jan 2020, the WHO designated the disease as
public health emergency - It designated this virus as 2019 Novel Corona
virus later it was renamed as - severe acute respiratory syndrome coronavirus 2
- (SARS-CoV-2) previously, it was referred to as
2019-nCoV.
4Corona Virus- Notorious past History
- 2 epidemics in the past belong to ß corona virus
.Mild illness belonged to a,?,? - 2002 Severe acute respiratory syndrome
Coronavirus (SARS-CoV) - 2012 Middle East respiratory syndrome
Coronavirus (MERS-CoV) - 2019 named SARS-CoV 2 as on genome sequencing
shared 79.5 identity to SARS-CoV. use
angiotensin-converting enzyme 2 (ACE2), the same
receptor as SARS-CoV , to infect humans (ZhouP
Nature 2020) - Designated severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) - Earlier referred to as 2019-nCoV.
- Viral mutations is key for explaining potential
disease relapses - In February 2020, the WHO designated the disease
COVID-19, which stands for coronavirus disease

6Routes Of Transmission
- Droplets do not linger in air
- Do not travel more than 2 meters
- Also detected in blood and stools
- According to a joint WHO-China report,
fecal-oral transmission did not appear to be a
significant factor in the spread of infection

12- Risk of Infection in Pregnant
- Women
- Pregnancy does not increase the risk to contract
the infection - than the general population.
- But Pregnancy alters the bodys immune system and
can cause - more severe symptoms with COVID-19.
- This is particularly true towards the end of
pregnancy, after 28 weeks .
13ICMR Guidelines
Effect of COVID-19 on Pregnancy
- Pregnant women do not appear more likely to
contract the infection than the general
population. However, pregnancy itself alters the
bodys immune system and response to viral
infections in general, which can occasionally be
related to more severe symptoms and this will be
the same for COVID- 19. - Reported cases of COVID-19 pneumonia in pregnancy
are milder and with good - recovery.
- Pregnant women with heart disease are at highest
risk (congenital or acquired).
14ICMR Guidelines
Effect of COVID-19 on Pregnancy
- In other types of coronavirus infection (SARS,
MERS), the risks to the mother appear to
increase in particular during the last trimester
of pregnancy. - There are case reports of preterm birth in women
with COVID-19 but it is unclear whether the
preterm birth was always iatrogenic, or whether
some were spontaneous. - The coronavirus epidemic increases the risk of
perinatal anxiety and depression, as well as
domestic violence. It is critically important
that support for women and families is
strengthened as far as possible that women are
asked about mental health at every contact
15- A small study of nine pregnant women in Wuhan,
China, with confirmed COVID-19 found no evidence
of the virus in their breast milk, cord blood or
amniotic fluid.
16 Concluded that the subjects didnt experience
more severe pneumonia than non-pregnant patients
17- A small retrospective study published in The
Lancet reviewed obstetric and neonatal outcomes
of seven pregnant women at a hospital in Wuhan
who had contracted COVID-19 in their third
trimesters. The outcomes for all seven women
were good none were admitted into intensive
care and all were discharged from the hospital.
18Cochrane Database on COVID19 (coronavirus
disease) - Pregnancy
- According to WHO, pregnant women
- do not appear to be at higher risk of
- severe disease.
- Furthermore, WHO reports that currently there is
no known difference between the clinical
manifestations of COVID-19 in pregnant and non-
pregnant women of reproductive age
19- A (WHO) report concluded that out of 147
pregnant women diagnosed with COVID-19, 8 had
what the WHO classified as severe disease and
1 were critical. - It was determined that they werent more likely
than non- pregnant people to develop
life-threatening illness
20- A study of 43 pregnancy women in New York with
confirmed COVID-19 published in the American
Journal of Obstetrics Gynecology in April
found that - unlike SARS and H1N1, pregnant women do not seem
to experience more severe illness from the
coronavirus compared to the general population.
21(No Transcript)
22- A study published as a letter in The New England
Journal of Medicine looked at testing data from
pregnant women who delivered between March 22
and April 4 at New YorkPresbyterian Allen
Hospital and Columbia University Irving Medical
Center in New York City. - Out of 215 patients, 88 percent of the women who
tested - positive for COVID-19 did not show any symptoms
23ACOG is advising caution based on the impact of
other respiratory illnesses (including
influenza/ SARS outbreak of 20022003), stating
that pregnant women should be considered an
at-risk population for COVID-19.
24- Precautions for all pregnant
women - Social distancing-at least 1 meter
- Avoid unnecessary visits outside home
- Avoid contact with people suffering from viral
illnesses - Practise Hand hygiene, Respiratory hygiene,
- Avoiding touching the face
- Work from home
25ROUTINE ANC CARE IN TIMES OF COVID
25
26 Routine ANC Visits Basic Principles
- Routine Antenatal visits to be kept minimal
- Consultation on phone or video conferencing
- Come alone or keep the number of people
accompanying to one - Follow hand hygiene,wear masks and
gloves,frequent hand sanitisation pre and post
visit
27MFM GUIDANCE FOR COVID 19
27
28Modified ANC routine In Current scenario
- 75 gm 2hr GTT instead of 50 gmGCT
- Cell-free DNA screening (at gt10 weeks) rather
than the combined test (ie, - nuchal translucency on ultrasound and serum
analytes) - Fetal kick counts hand outs to be given
- Teleconsultation
- Home BP monitoring
- Screen for symptoms on phone . Patients who are
symptomatic, suspected or COVID19 positive

33Indications for testing COVID 19 in
pregnancy-ICMR
- 1. A pregnant woman who has acute respiratory
illness with one of the - following criteria
- a history of travel abroad in the last 14 days (6
March 2020 onwards). - is a close contact of a laboratory proven
positive patient or - she is a healthcare worker herself or
- hospitalized with features of severe acute
respiratory illness. - 2. A pregnant woman who is presently asymptomatic
should be tested between 5 and 14 days of coming
into direct and high risk contact of an
individual who has been tested positive for the
infection.
33
34- Rapid Tests Guidelines
- In hotpots/cluster as per MOHFW and in large
- migration gatherings/evacuees centers
- All symptomatic ILI(fever,cough,sore throat,runny
nose) - a.Within 7 days-rRT-PCR b.After 7 days Antibody
test(If - Negative,confirmed by rRT-PCR)
34
35Test Method
- CDC recommends collection of a nasopharyngeal
swab specimen - Detected by reverse-transcription polymerase
chain reaction (RT-PCR) - Centers authorized by the government of India and
state governments - false negative rate of 10-30 even with two
serial swabs - In the near future, testing may be conducted by
Nucleic Acid Ampli cation Test (NAAT) or by
serological testing. - Serology faster and cheaper stay positive even
after 3 weeks of infection
35
36Course of COVID 19 In Pregnancy
- Most women have mild or moderate cold/flu like
symptoms. - Other reported cases of COVID-19 pneumonia in
pregnancy are milder and with good recovery - Women with severe diseases are those who have
associated comorbidities like DM,HT,
BMIgt40,respiratory disease or of advanced age - Pregnancy and Perinatal Outcomes of Women With
Coronavirus Disease - (COVID-19) Pneumonia A Preliminary Analysis.Liu
D, AJR Am J Roentgenol. 2020
37Course of COVID 19 In Pregnancy
- At present there is one published case of a woman
with severe COVID- 19 admitted at 34 weeks, in
the ICU with multiple organ dysfunction and
acute respiratory distress syndrome, requiring
extracorporeal membrane oxygenation - Data from Australia have identified that there
are significant increases in - critical illness in later pregnancy, compared
with early pregnancy - Liu Y, . Clinical manifestations and outcome of
SARS-CoV-2 infection - during pregnancy. Journal of Infection 2020
38Pregnancy complications due to COVID
- Meta analysis by Mascio D,Am J Obstet Gynecol
MFM. 2020 41 covid positive pregnant women were
studied
Baby
- Maternal
- preterm birth lt37 weeks (41.1 ),
- Stillbirth (2.4 )
- Admission to a NICU (10 )
- Neonatal death (2.4 )
- PPROM (18.8 ),
- preeclampsia (13.6 ),
- cesarean delivery (91.1 ),
- data reflect small numbers, related to severe
maternal illness, women mostly intubated,may not
directly due to fetal/neonatal infection with the - coronavirus
39Effect on Fetus
- Very recent evidence, suggests that the virus may
be transmitted vertically( Dong L JAMA 2020) 3
out of 33 neonates born to COVID positive
mothers tested positive for corona virus - Chen et al. found no evidence of COVID-19 in the
amniotic fluid or cord blood of 6 infants of
infected women(Lancet 2020)
40Effect on Fetus
- Currently, there are inadequate data on COVID-19
and - risk of miscarriage or congenital anomalies or
fetal growth restriction. - Data from the SARS epidemic are reassuring,
suggesting no increased risk of fetal loss or
congenital anomalies associated with infection
early in pregnancy - Shek CC, Pediatrics 2003 Oct
40
41 Management of COVID 19 Positive
- As per guideline by Indian Government,COVID 19
positive patients Based on the symptoms patient
are divided into 3 groups mild, moderate and
severe. - Mild cases are shifted to government designated
COVID CARE CENTER - Moderate cases are shfited to Dedicated COVID
Health Center - Severe cases are shifted to Dedicated COVID
Hospital

44- ANC Care in COVID POSITIVE
- ASYMPTOMATIC PATIENT
- Routine appointments, scans / tests
- should be delayed until after the recovery
- If it is deemed that obstetric care cannot be
delayed until after the period of isolation,
infection prevention and control measures should
be arranged locally to facilitate care preferably
at the end of the working day - If ultrasound equipment is used, this should be
decontaminated - after use in line with national guidance
44
45- Management of COVID Gravid
not in Labour - Symptomatic
- Medical Supportive therapy rest, oxygen
supplementation, fluid management and
nutritional care as needed. Maternal oxygen
saturation (SaO2) should be maintained at 95
percent during pregnancy, - Fetal Survellience a Bluetooth-enabled external
fetal monitor can transmit the fetal heart rate
tracing to the obstetric - provider. (ACOG) MONICA NOVII WIRELESS PATCH
SYSTEM. - Frequency as per gestation age and patient profile
45
46- Fever Paracetamol is the preferred drug
- Secondary bacterial infection pregnancy safe
antibiotics

47Use of medications to manage pregnancy
complications in covid positive
47
48 SPECIFIC MEDICATIONS
- Hydroxychloroquine in a dose of 600 mg (200 mg
thrice a day with meals) and Azithromycin (500
mg once a day) for 10 days has been shown to
give virological cure on day 6 of treatment in
100 of treated patients in one study( JHMI
Clinical Guidance for Available Pharmacologic
Therapies for COVID-19) - Alternative dosage regimens for
hydroxychloroquine are to give 400 mg - twice a day on day 1 and then 400 mg once a day
for the next four days - Antiviral lopinavir-ritonavir (400/100 mg) twice
daily for 14 days no difference in time to
clinical improvement or mortality - was seen ( Cao B 2020)
48
49- Side effects QTc prolongation, in particular, as
- well as cardiomyopathy and retinal toxicity)
- Published clinical data on either of these
- agents are limited.
49
50Post recovery Follow Up
- Scheduled ANC care that falls within the
isolation period should be - rearranged for post-isolation.
- If patient required hospitalisation for severe
illness , ultrasound for fetal growth
surveillance is recommended 14 days after
resolution of acute illness. - No evidence yet that (FGR) is a risk of COVID-19
- Two-thirds of pregnancies with SARS were affected
by FGR and a placental abruption occurred in a
MERS case,(Wong SF Am J Obstet Gynecol 2004
51- LABOUR MANAGEMENT
- MFM LABOUR AND DELIVERY GUIDANCE FOR
- COVID 19 AJOG 2020
51
52MFM LABOUR AND DELIVERY GUIDANCE FOR COVID 19
- Timing of Delivery
- In most women with non severe illness delivery
not indicated - In critically ill intubated pregnant woman gt32
weeks,delivery may relieve the extra metabolic
and pulmonary load. - Possible benefits of this need to be weighed
against the possible risks of worsening the
systemic status with a surgical intervention.
52
53- Mode Of Delivery
- Mode of birth should not be influenced by the
- presence of COVID-19,
- unless the womans respiratory condition demands
urgent delivery.
54Labour Triage
- A protocol should be in place in every maternity
unit to receive pregnant women in labour or
suspected labour with confirmed or suspected
COVID-19 infection. - The woman should call in advance to alert the
maternity unit about her arrival whenever this is
possible
54
55 Precaution for transmission prevention
- Designate rooms, or section of floor to be used
for suspected/confirmed COVID-19 positive
patients - Respiratory precautions
- Room type Negative pressure room is not required
- PPE should be used
- Minimize change in providers.
- Designate one team for COVID-19 patients.
55
5656
57- Precaution for transmission prevention
- Birth attendants should be limited to one named
- contact
- Separate delivery room and operation theatres
- Neonatal resuscitation corners located at least 2
m - away from the delivery table
- Patient should wear mask during labour and
delivery
58Attendence in Labour
- AT first arrivalfull maternal and fetal
assessment should be done - Assessment of the severity of COVID-19 symptoms
by a multidisciplinary team(Pulmonary,critical
care team) - Maternal observations including temperature,
respiratory rate and oxygen saturations - CTG-fetal surveillance
- Inform anesthetist and Neonatologist
59Care in Labour
- Maternal vital monitoring as standard with the
addition of hourly oxygen saturations. - Oxygen therapy for maternal reasons only to keep
oxygen saturation gt 94 - RCOG recommends continous electronic fetal
monitoring - Oxytocin augmentation is recommended to shorten
time to delivery - Early intervention with oxytocin and amniotomy
for slow and dysfunctional - labour
60Care in Labour
- An individualised decision to shorten the second
stage of labour with elective instrumental birth
in a symptomatic woman who is becoming exhausted
or hypoxic - In case of deterioration in the womans symptoms
assesment of risks and benefits of continuing
the labour versus proceeding to emergency
caesarean birth if this is likely to assist
efforts to resuscitate the woman
61Labour management
- All care should be taken to reduce need for blood
transfusion - In addition to standard oxytocin, consideration
should be made for prophylactic tranexamic acid
and misoprostol (400 mcg buccally) - avoiding delayed cord clamping. RCOG recommends
delayed clamping - Cord blood banking can be done(ACOG)(risk of
COVID-19 transmission by blood products has not
been documented and is unclear at present)
62Anesthesia Consideration
- Early epidural to minimize need for general
anesthesia in the event of emergent cesarean
section - COVID-19 is not a contraindication to neuraxial
anesthesia - Iv analgesia should be avoided
- General anesthesia is considered an aerosolizing
procedure, should be avoided,if not then special
personal protective equipment should be worn.
63 Infant evaluation CDC recommendations
- Mothers with suspected COVID-19 and unknown test
results (either pending or not tested) infants
born to such women are not COVID- 19 suspects - Mothers with known COVID-19 infants are COVID-19
suspects, and they should be tested, - isolated from other healthy infants cared for
according to infection - control precautions for patients with confirmed
- or suspected COVID-19
64- Neonatal care of COVID positive patients
- No evidence of COVID-19 transmission through
breastmilk - However, given risk of neonatal morbidity from
transmission through maternal exposure, CDC
recommend separation of mother and neonate after
discussion with mother - Separation not required if infant tests positive
- RCOG and FOGSI recommends breast feeding with
discussion of risk - factors with mother
65 Breastfeeding considerations
- Breast milk provision (via pumping) is
encouraged. - The CDC recommends that during temporary
separation, women who intend to breastfeed
should be encouraged to express their breast
milk to establish and maintain milk supply. - Before expressing breast milk, women should
practice appropriate hand/skin hygiene washing
not just hands but also breast prior to pumping.
65
66- Period of separation- AAP
- until patient is afebrile for 72 hours without
use - of antipyretics and
- her respiratory symptoms are improved and
- at least two consecutive SARS-CoV-2
nasopharyngeal swab tests collected 24 hours
apart are negative.
66
67PRECAUTIONS WHILE BREAST FEEDING
- Wash hands before touching the baby, breast pump
or - bottles.
- Avoid coughing or sneezing on the baby while
feeding. - Consider wearing a face mask, if available, while
feeding - or caring for the baby.
- Where a breast pump is used, follow
recommendations for pump cleaning after each
use. - Considering asking someone who is well to
- feed the baby
68Postnatal care for COVID postive
- Continued medical evaluation for respiratory
status and symptoms and standard practices of
routine postnatal care - Hygiene related to the puerperium and hand
hygiene - Advice on management of engorged breasts when
feeding has not been established and measures to
enhance breastfeeding after the isolation period
is completed. - Healthy, nutritious diet to recover from the
infection and build - immunity
69 Post partum care in Non Covid Patients IN
Current Scenario
- Expedited Discharge Planning
- All vaginal deliveries should have a goal of
discharge on postpartum day 1, or even same day
if possible for selected women. - All cesarean deliveries should have a goal of
discharge on postoperative day 2, with
consideration of postpartum day 1 discharge if
meeting milestones. - Discuss anticipated maternal discharge with
pediatrics/neonatology to determine timing of
infant discharge. - Home care with supplies for blood pressure follow
up will be critical to - expediting discharge of patients with a
hypertensive disorder.
70- Investigational approaches in
treatment - Redesmivir nucleotide analogue that has activity
against (SARS-CoV-2) in vitro.I.V agent
systematic evaluation of the clinical impact of
remdesivir on COVID-19 has not yet been
published. - IL-6 pathway inhibitors no published clinical
data supporting its use - Convalescent plasma
71- Convalescent plasma
- A case series described administration of plasma
from donors who had completely recovered from
COVID-19 to five patients with severe COVID-19
on mechanical ventilation and persistently high
viral titers despite investigational antiviral
treatment . - The patients had decreased nasopharyngeal viral
load, decreased disease severity score, and
improved oxygenation by 12 days after
transfusion, but these findings do not establish
a causal effect. - Finding appropriate donors and establishing
testing to confirm neutralizing activity of
plasma may be logistical challenges.
71
72MTP/ Abortion care services RCOG
- 1.4 Priority
- Abortion care is an essential part of health
care for women services must be maintained
even where non-urgent or elective services are
suspended.
72
73MTP/ Abortion care services RCOG
is time-sensitive. should be paid to
- providing care as early as possible given
gestational limits. - Organise access to abortion care
- so that delays are minimised
73
74MTP/ Abortion care services RCOG
Suspected/ Confirmed COVID 19 If the woman
requires face-to-face assessment but the
pregnancy is likely to be under 20 weeks
gestation, care should be booked after at least
7 days since the illness started (unless she
continues to be unwell, excluding a persistent
cough).
74
75MTP/ Abortion care services RCOG
Suspected/ Confirmed COVID 19 If the woman is
suitable for an early medical abortion at home,
she should be advised to take this approach if
she has no or mild symptoms (persistent cough is
acceptable), and before the pregnancy reaches 10
weeks gestation
75
76MTP/ Abortion care services RCOG
- Suspected/ Confirmed COVID 19
- If the abortion cannot be safely deferred and
face-to-face contact is necessary, request the
woman attend at a specific time (typically end
of clinic, in a location that is equipped to
manage COVID-19 patients) so correct IPC
(infection prevention and control) measures can
be put in place. The woman should be given a
surgical face mask to wear and asked to wash her
hands on arrival.
76
77 MTP/ Abortion care services RCOG
Suspected/ Confirmed COVID 19 If surgical
abortion is performed Perform vacuum aspiration u
nder LA or IV sedation where feasible to avoid
need for GA Consider whether Spinal Anesthesia or
iv sedation would be more appropriate than an
anaesthetic requiring ventilation.
77
78MTP/ Abortion care services RCOG
- Suspected/ Confirmed COVID 19
- Consider checking full blood count, clotting and
blood group if unwell. - Ensure that best practice is followed to reduce
risk of transmission of infection (e.g. limit
number of people in theatre, use PPE and
decontaminate area after procedure as
recommended by PHE).
78
79MTP/ Abortion care services RCOG
- Self-isolation due to contact with suspected
COVID-19 same practices as described for
suspected cases to be followed
79
80MTP/ Abortion care services RCOG
- Given that it is especially important to reduce
contact during the COVID-19 pandemic, providing
a second dose of 400mcg misoprostol for women
to use 34 hours after the first if they have
completed the abortion would seem prudent.
80
81 MTP/ Abortion care services RCOG
- There is evidence that NSAIDs (e.g. ibuprofen
400800 mg) are effective for abortion-related
pain, but also evidence that paracetamol is not. - Use paracetamol in preference to ibuprofen for
symptoms of confirmed/suspected COVID-19 but
ibuprofen can continue to be used in other
circumstances
81
82MTP In Indian Context
- MTP Medication schedule H medication and cannot
be prescribed online or on Telemedicine - Follow all general principles of practice as per
MTP Act - Assessment of patient and filling of all consent
forms is essential
82
83MTP In Indian Context
Follow Additional Local Government Guidelines
for COVID19 as appropriate for example in Noida
it is now mandatory to test for SARSCov2 prior
to any operative procedure.
83
84MTP In Indian Context
- In Delhi at the hospital entrance a complete
evaluation for any influenza like illness/
travel history / contact with suspected/
confirmed COVID19 case /hotspot area residence
etc is taken and then the woman is referred to
general OPD or a separate COVID care centre
(test not done routinely for all operative
procedures)

ECTOPIC PREGNANCY Mx in COVID 19 PANDEMIC
- proceed with minilap
- Concerns re Methotrexate as it Is a
immunosuppresant. Is self isolation required? - No because it is approx two one off doses in
women who have healthy Immune systems - Rare cases WBC count can fall so Follow up is
