Observation of the effect of dizocine sedation on brachial plexus nerve block / 中国基层医药

ABSTRACT

Objective:To observe the application value of dizocine sedation in brachial plexus nerve block.Methods:From January 2016 to December 2018, 80 patients with brachial plexus block anesthesia in the Second People's Hospital of Tongxiang were selected and divided into two groups according to the random number table method, with 40 cases in each group.The control group was not given sedation intervention, while the observation group was given dizocine sedation.The heart rate, mean arterial pressure, blood oxygen saturation and Ramsay scores at different time points were compared between the two groups.The anesthetic effect of the two groups was analyzed.Results:The onset time of sensory block in the observation group[(8.86±0.92)min] was significantly shorter than that in the control group[(11.43±1.08)min]( t=11.457, P<0.05). The duration of sensory block[(729.95±54.43)min] and the duration of analgesia[(879.96±165.52)min] in the observation group were significantly longer than those in the control group[(600.73±49.86)min, (750.27±261.19)min]( t=11.072, 2.653, all P<0.05). There were no statistically significant differences in the mean arterial pressure, heart rate and blood oxygen saturation at each time point between the two groups before operation (all P>0.05). The mean arterial pressure and heart rate of the observation group were significantly lower than those of the control group at 15 min, 30 min after operation and at the end of operation (all P<0.05). The Ramsay score between the two groups had no statistically significant difference before operation ( P>0.05). At 15 min, 30 min after operation and at the end of surgery, the Ramsay scores of the observation group were (4.08±0.54)points, (4.15±0.37)points, (2.96±0.19)points, respectively, which were significantly higher than those of the control group [(1.79±0.27)points, (1.77±0.16)points, (1.93±0.14)points], the differences were statistically significant ( t=23.989, 37.341, 27.602, all P<0.05). Conclusion:After dizocine sedation is used in brachial plexus block patients, the vital signs fluctuate slightly and the sedation effect is obvious.
