Objective: The investigators sought to investigate the analgesic efficiency of lidocaine
spray, paracervical block (PCB) with lidocaine and PCB with lidocaine plus lidocaine spray
combination in patients undergoing first-trimester surgical abortion.
Methods: A randomized, double-blind, placebo-controlled clinical trial was conducted on 108
women with the request of pregnancy termination.The subjects were randomly assigned into
four groups: PCB (n=27), lidocaine spray (n=27), PCB plus lidocaine spray (n=27) and
placebo(n=27).Intraoperative and postoperative pain scores were measured with a standard
Visual Analog Scale (VAS).
