Hemodynamic Stability of Bupivacaine With and Without Adrenaline for Paracervical Block for Cervical Conization

Summary

Cervical conization is done for pre-cancer disease. The procedure is performed with local anesthesia and general anesthesia. Local anesthesia is given by paracervical block, and several different local anesthetics is being used including bupivacaine with and without adrenaline. Adrenaline might reduce local bleeding and reduce toxicity of bupivacaine by reducing absorption, but might affect cardiovascular function. This study will examine this effect.
