Intrauterine local anesthesia
Background:
The first local anesthetic to be discovered was cocaine an alkaloid in
large amount (0.6 to 1.8%) on the leaves of Erythroxylon coca a shrub growing in
the Andes Mountains. Vast quantities were consumed orally and annually. The plant
ash when chewed releases the plant alkaloid and absorbed across the mouth mucous
membrane. In 1880 Niemann noted that the tongue was numb with no sensation
upon chewing this substance. It is well known that Lidocaine was absorbed across
the mucous membrane.
Anesthesia for gynecological surgery procedure is not very satisfactory in certain

in the hospital. Paracervical block uses from 10 to 18 cc of 1% Lidocaine a relatively
large amount. The VAS score from the block itself is between 19 to 69 mm. Aquoted
study showed that paracervical block does not significantly decrease pain with IUD
insertion.
Study Design:
This is a retroactive study comparing patients with gynecological
procedure without any anesthesia and with ° intrauterine 1% Lidocaine injected into
the uterine cavity. Pain was evaluated with the VAS score at 1. Instrument insertion,
2. Actual procedure and 3. 5 minutes post operation.
The procedures include 1. IUD insertion, 2. SIS, 3. Endometrial biopsy, 4. D&C.
Others such as IUI , sterilization etc may also be included. ,
Results:
After 3-5 cc of 1% Lidocaine injection into the uterine cavity, the median
VAS score is only about 5 mm. On testing serum Lidocaine at 5 minutes after
injection the serum level is below 1.5 mg/L. Our normal Lidocaine therapeutic level
is 1.5 to 5 mg/L. Without anesthesia the VAS score is about 75 mm.
Conclusion:
Injecting 3-5 cc of 1% Lidocaine into the uterus results in very good
anesthesia. Knowing the serum level is below 1.5 mg/L this procedure can be used
with impunity.
