DISTENDING MEDIA
Need to distend uterus to view as uterus is almost closed structure.
Minimum 45mm of Hg for diagnostic Upto 70mm of Hg for operative If more than MAP ,more chances of
overload Gaseous and liquid High and low viscosity medium
![Page 19: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/19.jpg)
Carbon dioxide
Neatness Doesn't damage instruments Doesn't mess up office/OR CO2 and bleeding incompatible CO2 and blood form obscuring
bubbling foam Cannot flush debris CO2 embolism rarely
![Page 20: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/20.jpg)
CO2
Insufflation should not exceed 100ml/min
Unlike laparoscopy which are in litres/min
Use only hysteroinsufflator Ideal for diagnostic office
hysteroscopy
![Page 21: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/21.jpg)
HYSKON
32 percent dextran 70 in dextrose Immiscibility with blood Excellent visualization even in active
bleeding Compatible with electrosurgery and lasers Outflow less due to high viscosity Hyskon allergic reaction 0.05% treat like
anaphylaxis Pulmonary edema 0.11% due to overload
as it pulls water into intravascular space.
![Page 22: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/22.jpg)
HYSKON
Fibrinoplastic action leading to bleeding diathesis
Clogs instruments if instruments are not washed immediately with hot water
Remains in bloodstream for 4-6 weeks
![Page 23: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/23.jpg)

NORMAL SALINE
Safest Instilled with 2-3 litres bag from 6-8
feet Continuous high flow required Cannot use monopolar cautery as it
contains electrolytes, bipolar can be used.
Still overload can occur which can be treated with diuretics
Stop if deficit is 1.5 litres
![Page 25: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/25.jpg)
1.5%GLYCINE AND 3%SORBITOL Taken from urology Hypotonic Metabolized to CO2 and free water Female brain cells cannot pump cations
due to progesterone action so more prone for cerebral edema.
Check osmolality and sodium minimum pre op intra op and 4 hr post op
Stop if >500ml deficit, Can use monopolar
![Page 26: Hysteroscopy](https://reader036.fdocuments.net/reader036/viewer/2022062405/55616069d8b42a654b8b4c29/html5/thumbnails/26.jpg)
5%MANNITOL AND 2.2%GLYCINE Both are safer and isoosmolar Mannitol is diuretic also Studies have shown that glycine2.2%
is very safe upto 1000ml deficit Can use monopolar Keep strict inflow and outflow Take into account the fluids infused
by anesthesiologist as RL commonly given is hypoosmolar

CONTRAINDICATIONS
Active PID Active profuse bleeding Recent perforation Pregnancy Cancer cervix Systemic disorders affecting fluid
and electrolytes

PROCEDURE
Cervical priming and dilatation if needed
Per vaginal examination to know the position of uterus
Vaginoscopic technique Systematic examination Operations with correct use of
electrosurgery and lasers

CONCLUSION
Hysteroscopy is a part of every gynecological surgeon’s armamentarium
Generally a low risk technique using natural pathway.
Supersedes laparoscopy in philosophy of MIS
