Abstract:
Objective:To analyze the effect of ultrasound-guided stellate ganglion block combined with dexmedetomidine on Narcotrend index and pain degree after hip replacement.Methods:Seventy patients who underwent hip replacement in the Third People′s Hospital of Dalian City from January 2018 to June 2019 were selected. The patients were divided into control group and experimental group by random digits table with 35 cases in each group. Before induction of anesthesia, the patients in control group were given dexmedetomidine 0.25 μg/(kg·h) venous pump injection; the patients in experimental group were anesthetized by ultrasound-guided stellate ganglion block combined with dexmedetomidine 0.25 μg/(kg·h). The anesthesia recovery, Narcotrend index pain degree and adverse reaction were compared between 2 groups.Results:The postoperative finger-pointing-nose time, spontaneous breath recovery time, head up time and eye opening time in experimental group were significantly shorter than those in control group: (17.78 ± 2.33) min vs. (22.07 ± 2.59) min, (2.50 ± 0.51) min vs. (3.61 ± 0.58) min, (12.01 ± 1.33) min vs. (18.01 ± 2.05) min and (7.35 ± 1.18) min vs. (9.53 ± 1.46) min, and there were statistical differences ( P<0.01). There was no statistical difference in the Narcotrend index at the time of going into the operating room between 2 groups ( P>0.05); the Narcotrend index at the time of intubation, 5 min after intubation and 10 minutes before conclusion of the surgical procedure in experimental group was significantly higher than that in control group (95.15 ± 3.66 vs. 89.77 ± 4.39, 90.36 ± 3.71 vs. 86.44 ± 4.28 and 88.50 ± 4.06 vs. 82.22 ± 4.17), and there was statistical difference ( P<0.01). The static and dynamic visual analogue score 4, 8, 12, 24 and 48 h after operation in experimental group was significantly lower than that in control group, and there was statistical difference ( P<0.01). No adverse reaction associated with ultrasound-guided stellate ganglion block was observed in the experimental group. Conclusions:Ultrasound-guided stellate ganglion block combined with dexmedetomidine has a significant anesthetic effect in hip replacement patients, which can promote postoperative recovery, as well as improve Narcotrend index and pain level.
