Abstract:
Objective:To explore the effect of ultrasound-guided superficial cervical plexus block on chronic pain after intracranial space-occupying resection by suboccipital retrosigmoid approach.Methods:A single-center, randomized, double-blind, parallel controlled trial was conducted on 106 consecutive patients who underwent selective resection of acoustic neuromas in the cerebellopontine angle through the suboccipital retrosigmoid approach in Beijing Tiantan Hospital, Capital Medical University from November 2019 to April 2021. The patients were divided into experimental group and control group by random number table method, with 53 cases in each group. The patients in experimental group underwent superficial cervical plexus block with 0.5% ropivacaine under ultrasound-guided, and the patients in control group received an equal volume of 0.9% sodium chloride. Three months after surgery, the patients were followed up for chronic postoperative pain and the chronic postoperative pain rating scale (NRS) score via telephone. The nature of chronic pain was evaluated using the short-form McGill pain questionnaire-2 (SF-MPQ-2).Results:The incidence of chronic postoperative pain and the NRS score of chronic postoperative pain in experimental group were slightly lower than those in control group: 39.6% (21/53) vs. 50.9% (27/53) and 0 (0, 2) scores vs. 1 (0, 3) scores, but there were no statistical difference between the two groups ( P>0.05). There were no statistical difference in SF-MPQ-2 various scores and total score after surgery between the two groups ( P>0.05). Conclusions:Ultrasound-guided superficial cervical plexus block has a certain analgesic effect on chronic pain after intracranial space-occupying resection by suboccipital retrosigmoid approach, but it still requires further verification through an adequate sample size.
