VAS – Visual analogue scale, NS – Normal saline group, IV – Intravenous, IP – Intraperitoneal dexmedetomidine. *Level of significance between Groups NS and IV. †Level of significance between Groups IV and IP. ‡Level of significance between Groups NS and IP. P<0.02 is considered statistically significant
