Objectives: Many women experience pain and discomfort after hysteroscopic procedure. Pain and discomfort after hysteroscopic procedures can be explained by the cervical dilatation, intrauterine manipulation, and/or hydrodistension. This study designed to evaluate the efficacy of intrauterine levobupivacaine instillation for pain control in women undergoing diagnostic hysteroscopy.
Materials and methods: One hundred and twenty (120) women scheduled for diagnostic hysteroscopy and endometrial biopsy due to uterine bleeding were included in this study and randomized either to levobupivacaine group or controls. At the end of hysteroscopy, 5 mL of 0.5% levobupivacaine was instilled intrauterine in levobupivacaine group, while 5 mL of 0.9% saline was instilled intrauterine in controls. Participants were kept in the hospital for 12 h after diagnostic hysteroscopy to detect the postoperative (PO) pain intensity using visual analog scale (VAS), and PO required analgesics.
Results: The VAS was significantly lower in levobupivacaine group compared to controls 3 h. PO (1.31 ± 1.02 vs. 1.62 ± 0.76, respectively), (P = 0.01), 6 h. PO (0.81 ± 1.24 vs. 1.53 ± 0.88, respectively), (P = 0.004), and 9 h. PO (0.55 ± 1.25 vs. 1.12 ± 0.95, respectively), (P = 0.01). The total PO required analgesics were significantly lower in levobupivacaine group compared to controls (P = 0.005).
Conclusion: The intrauterine levobupivacaine instillation was simple, and effective for pain relief after diagnostic hysteroscopy, it significantly decreased pain score assessed by VAS at 3, 6, and 9 h., PO, and it significantly decreased PO required analgesics.
