evidence: Regarding level of sensory blockade, no significant difference was found among three groups (Mean sensory block in Gr I was 8.33±0.48, Gr II 8.50±0.78 and in Gr III 8.60 ± 0.77) .
intervention: group II lignocaine1% (9ml) with neostigmine 100μg in saline (1ml) and group III received lignocaine 1% (9ml) with neostigmine 200μg in NS (1ml)
comparator: Group I received lignocaine 1% (9ml) with normal saline (1ml),
