0.75-2% of pregnant women undergo non-obstetric surgeries, most commonly for appendicitis or cholecystitis. Anesthesiologists must provide safe anesthesia for both the mother and fetus by considering the physiological changes of pregnancy and avoiding drugs that could harm the fetus or stimulate preterm labor while maintaining normal maternal function and uteroplacental blood flow and oxygen delivery. Regional anesthesia should be used when possible to prevent complications like hypotension, hypovolemia, hypoxia, and hypothermia that could endanger the fetus.

2. 0.75-2% pregnant women undergo
surgeries
Most common indication acute
abdominal infection
Appendicitis(1:2000)
Cholecystitis (8:10000)
3. Directly related to pregnancy - e.g.
Cervical encirclage
Indirectly related to pregnancy - e.g.
Ovarian Cystectomy
Not related to pregnancy -
e.g.Appendicectomy (m.c )
4. Anaesthesiologist who care for pregnant
patient undergoing non-obstetric surgery must
provide safe anaesthesia for both mother &
foetus.
To maintain maternal safety the physiological
&anatomical changes of pregnancy must be
considered,anaesthetic technique & drug
administration modified accordingly.
5. Foetal wellbeing is related to avoidance of
foetal asphyxia& teratogenic drugs & preterm
labour.
Optimization & maintenance of normal
maternal physiological function.
Optimization & maintenance of uteroplacental
blood flow & 02delivery.
Avoidance of unwanted drug effects on the
foetus.
6. Avoidance of stimulating myometrium.
Avoidance of awareness during GA.
Using regional anaesthesia, if possible.
To prevent hypotension, hypovolemia, hypoxia
and hypothermia
12. Teratogenicity is defined as the ability of a drug to cause
fetal abnormalities or deformities.
During the period of organogenesis the embryo is most
vulnerable to teratogenic effects .
17. UTEROPLACENTAL PERFUSION &FETAL
OXYGENATION
Most serious risk during non obstetric
surgery is intrauterine asphyxia.
Fetal oxygenation depends on maternal
oxygen delivery and uteroplacental
perfusion
