Comparison of lidocaine spray and paracervical block application for pain relief during first-trimester surgical abortion: A randomised, double-blind, placebo-controlled trial

Abstract

Surgical abortion is one of the most frequently performed gynaecological procedures and its associated pain has always been a problem in gynaecology. Here we studied the analgesic efficacy of lidocaine spray and paracervical block (PCB) in patients undergoing first-trimester surgical abortion. A randomised double-blind placebo-controlled study was conducted on 108 women requesting pregnancy termination. The subjects were randomly assigned into four groups: Group 1 (PCB plus lidocaine spray) (n=27), Group 2 (PCB) (n=27), Group 3 (lidocaine spray) (n=27) and Group 4 (placebo) (n=27). Intra-procedural and post-procedural pain scores were measured with a standard visual analogue scale (VAS). The median VAS scores during procedure in placebo, lidocaine spray, PCB plus lidocaine spray and PCB groups were 8 (7–9), 5 (4–8), 4 (3–4) and 5 (3–5), respectively. The most effective method of pain relief during first-trimester abortion can be achieved through a combined use of PCB plus lidocaine spray. Therefore, lidocaine spray is a non-invasive complementary anaesthetic method versus traditional PCB for first-trimester surgical abortion.
