Summary
Paracervical block with lidocaine effectively reduced pain during cervical manipulation in hysteroscopic sterilization. However, it did not significantly alleviate pain during device placement in the upper uterus or fallopian tubes.
Area of Science:
- Gynecology
- Pain Management
- Minimally Invasive Surgery
Background:
- Office hysteroscopic sterilization is a common procedure.
- Pain management during hysteroscopic sterilization is crucial for patient comfort.
- Paracervical block is a potential method for pain relief.
Purpose of the Study:
- To evaluate the effectiveness of paracervical block (PCB) using 1% lidocaine compared to a saline placebo.
- To assess pain relief during key stages of office hysteroscopic sterilization.
Main Methods:
- A randomized, placebo-controlled, blinded study involving 80 women undergoing hysteroscopic sterilization.
- Participants received either a paracervical block with 1% lidocaine or a normal saline injection.
- Pain was measured using a visual analog scale (VAS) at multiple procedural points.
Main Results:
- Lidocaine significantly reduced pain during tenaculum placement and cervical os traversal (P<.001).
- No significant difference in pain was observed during device placement in the tubal ostium (P=.33).
- Procedural time and group assignment were significant factors influencing pain scores (P=.047 and P<.01, respectively).
Conclusions:
- Paracervical block with 1% lidocaine is effective for managing pain associated with cervical manipulation in hysteroscopic sterilization.
- PCB does not significantly reduce pain during the upper uterine or tubal manipulation stages of the procedure.
