Correlation between electrical stimulus intensity and postoperative complications of puncture trigeminal ganglion radiofrequency thermocoagulation / 实用医学杂志

ABSTRACT

Objective To investigate the relationship between electrical stimulus intensity and postopera-tive complications of puncture trigeminal ganglion radiofrequency thermocoagulation (PTGRT). Methods 86 pa-tients with trigeminal neuralgia (TN) on the second and the third branch underwent trigeminal ganglion radiofre-quency thermocoagulation in Xuanwu Hospital , Capital Medical University from June 2013 to December 2015 enrolled in this study. Electrical stimulus intensity in surgery and postoperative pain VAS score , numbness score, masseter muscles score and complications were recorded at 0, 24 and 48 hours post-surgery. Correlations among electrical stimulus intensity in surgery and postoperative pain VAS score,numbness score, masseter mus-cles score were analyzed. Result The 86 patients had different degrees of facial numbness , some patients had different degrees of masseter weakness , and 2 patients had mild sialorrhea in two days after PTGRT without serve complications. Eighty-three patients (96.51%) had no pain, and VAS score wass 0 at 0, 24 and 48 hours post-PTGRT. Electrical stimulus intensity in surgery had apparent negative correlation with numbness score at 0 , 24 and 48 hours popst-PTGRT (P < 0.01), with negative correlation with masseter muscles decreasing at 48 hours post-PTGRT (P < 0.05). Conclusion Suitable temperature and time in PTGRT were needed to be chose ac-cording to the electrical stimulus intensity.
