Comparison of ring block
, dorsal penile nerve block, and topical anesthesia for neonatal circumcision: a randomized controlled trial.
Infants who received a combination of Ring Block
and Sucrose had a lower FLACC score than infants who received Ring Block
alone for the first assessment during circumcision (p < .004).
No comparison was done using a topical agent or the circumferential ring block
, although previous research has shown these methods to be similar, or in some cases superior, to DPNB.
The ring block
around the base of the swelling was performed using 2% Lidocaine hydrochloride.
Anesthesia of teat was achieved using ring block
technique using local anesthetic 2% Lignocaine hydrochloride (Lox (b)).
The udder and lacerated teat were cleaned using Potassium permanganate solution and ring block
of right hind teat was done at the base of the teat using 2% Lignocaine solution.
