Abstract:ObjectiveTo observe the effect of epidural use of Dexmedetomidine and Ropivacaine on patients undergoing repeated cesarean section.MethodsA total of 40 parturient,treated in Jiangsu Women and Children Health Care Hospital from December 2015 to December 2016,scheduled for repeated cesarean section under epidural anesthesia were selected randomly.According to the random number table method,the patients were divided into group D and group R,with 20 patients in each group.0.75%Ropivacaine 15 ml was administered epidurally,with addition of 0.5 μg/kg of Dexmedetomidine in group D,and 2 ml of normal saline in group R.Mean arterial pressure(MAP),heart rate(HR)before anesthesia (T0),at 10 min after administration of the specific drugs (T1),at 30 min after administration of the specific drugs(T2),and end of surgery (T3)were recorded.The onset time of epidural sensory block,maximum sensory analgesic level,the time to maximum sensory analgesic level,the time of sensory block were collected.The modified Bromage scale,Ramsay grade and grade of traction reaction at T2,cases who used remifentanil,incidence of respiration inhibition and shiver were also assessed.Blood from umbilical veins was collected for blood gas analysis.The Apgar scores were evaluated at 1 and 5 min.ResultsThere was no significant difference in the MAP and HR at T0,T1,T2and T3between the two groups(P>0.05).The onset time of epidural sensory block and the time to maximum sensory analgesic level in group D was shorter than that in group R,and the time of sensory block in group D was longer than that of group R,with significant difference (P<0.05).The degree of sedative satisfaction in group D was higher than that in group R,the effect of traction reaction in the operation in group D was less than that of group R,and the proportion of the use of Remifentanil in group D was lower than that of group R,and the incidence of respiratory inhibition in group D was lower than that in group R,with significant difference (P<0.05).The score of Apgar at 1 min after birth in group D was higher than that in group R,with significant difference(P<0.05).ConclusionFor patients undergoing repeated cesarean section,epidural use of Dexmedetomidine combined with Ropivacaine can enhance the anesthetic effect,without obvious adverse maternal or neonatal effects.
