Analysis of the Effect of Concentration Increasing Method on the Analgesic Effect of Epidural Intermittent Pulse Injection of Ropivacaine in Parturients at Different Times
Objective:Exploring the analgesic effect of concentration increasing method controlled epidural intermittent pulse injection of ropivacaine on parturients at different times.Method:A total of 140 first-time parturients with full-term pregnancy admitted to Zhangzhou Hospital of Fujian Medical University from January 2021 to January 2023 were selected as study objects and divided into control group(n=69)and observation group(n=71)according to random number table method.Both groups were given ropivacaine by PIEB.The control group was given labor analgesia with fixed concentration,while the observation group was given labor analgesia by concentration increment method.The pain degree,analgesic drug consumption,pain outbreak and adverse reactions of the two groups were observed at different times.Result:The VAS scores in observation group were lower than those in control group 15 min after full uterine opening and delivery,and the difference was statistically significant(P<0.05).The total dose of ropivacaine and sufentanil in observation group were lower than those in control group,and the patient controlled Epidural analgesia(PCEA)press times were lower than those in control group,the difference was statistically significant(P<0.05).The incidence of pain outbreak in the observation group was 5.63%,which was lower than 15.94%in the control group,and the number of additional analgesic drugs was less than that in the control group,the difference was statistically significant(P<0.05).The incidence of adverse reactions in observation group was 16.90%,which was lower than 31.88%in control group,and the difference was statistically significant(P<0.05).Conclusion:The use of concentration increasing method for programmed epidural intermittent pulse injection of ropivacaine for pain relief in primiparous women during childbirth has a good analgesic effect,with fewer pain outbreaks and reduced dosage of pain medication and adverse reactions.
