Haemodynamic stability after paracervical block: A randomized, controlled, double-blind study comparing bupivacaine-adrenaline with bupivacaine.

Background: Paracervical block is widely used in gynaecological interventions on cervix and uterus. Many surgeons add adrenaline 100 μg or pitressin 3-5 IU in a total volume of 10-20 mL to reduce total blood loss. We wanted to examine haemodynamic stability in healthy patients given bupivacaine with and without adrenaline.
