However, the optimal concentration of levobupivacaine for labor analgesia has not been adequately studied. The objective of this retrospective study was to compare the analgesic effect of levobupivacaine between 0.06% and 0.1% both combined with 2 μg/mL of fentanyl. Methods: Primiparous women (ASA I, II) who delivered their babies to our hospital using combined spinal epidural analgesia and patient-controlled epidural analgesia between August 1, 2011 and September 30, 2011 were included into this retrospective study. The analgesic solution for epidural administration was 0.06% levobupivacaine with 2 μg/mL of fentanyl between August 1 and 31, and 0.1% levobupivacaine with 2 μg/mL of fentanyl between September 1 and 30. Their anesthetic and obstetric charts were reviewed to compare obstetric outcome, anesthetic intervention, and patients’ satisfaction. Results: There were 46 women fulfilling the inclusion criteria: 23 women in 0.06% group, and 23 women in 0.1% group. The number of patients who needed more than 3 requests for one actual bolus was significantly higher in the 0.06% group (P 0.05). Conclusion: Our results revealed that 0.06% levobupivacaine combined with 2 μg/mL fentanyl does not provide sufficient analgesic effects for epidural labor analgesia. It seems that levobupivacaine has not been adequately studied after its withdrawal from the US market. Further studies should be conducted to determine the optimal concentration of levobupivacaine for epidural labor analgesia.展开更多

Concerns about pain in labor remain a hot topic, and its popularity gets more common day by day as more women become aware of their rights to achieve a better quality of care during labor. There are various non-pharmacologic (transcutaneous electrical nerve stimulation, hydrotherapy, intradermal water injections and acupuncture) and pharmacologic treatments (nitrous oxide, opioids and regional analgesia techniques: spinal, epidural and combined epidural analgesia) available today. Among these, epidural analgesia offers the most effective form of pain relief and is considered to be the gold standard of labor analgesia. Despite having labor analgesic services, most women still go through painful labor due to lack of knowledge regarding it, particularly in developing countries. The main source of information regarding pain reliefs is from friends and relatives, revealing the lack of information from caregiver’s side. So this study reflects that there is a wide gap in the communication between pregnant women and obstetricians. It supports the fact that obstetricians through the practice of routinely offering labor analgesia can significantly improve the maternal and perinatal outcomes of pregnancy. Provision of standardized epidural analgesia information at an appropriate time in their pregnancy may benefit them by the practice of mutual decision-making. Thus, it may prevent women from making a difficult choice of cesarean section to avoid the fear of painful labor.展开更多

Methods A total of 220 primiparaes with full-term pregnancy, monocyesis and fetal head presentation without any obstetrical or systematic complications were chosen and divided into analgesic group and control group (110 in each group). The mixture of bupivacaine and anisodamine was injected into the epidural space of the parturients in the analgesic group while those patients in the control group did not receive any analgesics. Results The analgesic effect was satisfactory (91.8%), and no side effects occurred in the second stage of labor. The instrument delivery rate was lower in the analgesic group, and there was no significant difference between the two groups in neonatal Apgar’s score. Conclusion The method is feasible in clinic for labor pain relief without increasing the rate of dystocia and complications of delivery.展开更多

It is actually called “childbirth analgesia” in medicine. Labor analgesia, as its name implies, is the use of various methods to reduce or even eliminate the pain during labor. With the development of anesthesiology and pain, it has been widely used in foreign countries, especially in some developed countries in the West. The rate of labor analgesia in the United States is > 85%, and even as high as 90% in Britain. The best childbirth analgesia should include side effect is small to puerpera and fetus, exact analgesic effect, quick effect, maintain time is long, can satisfy normal labor course;puerpera is awake, can cooperate childbirth and do not affect uterine contraction, and do not affect labor course progress. In 2000, WHO proposed that medical institutions should provide various labor analgesic services for parturient women to reduce labor pain as much as possible. Encourage the use of non-pharmaceutical analgesic techniques. In this paper, the effects of different modes of labor analgesia on neonates are described as follows.展开更多

Methods: Puerperae who underwent vaginal delivery under combined spinal-epidural anesthesia for labor analgesia in Lincheng People's Hospital between June 2014 and March 2017 were selected and randomly divided into three groups, group A received 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, group B received 25 μg large-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, and group C received ropivacaine epidural anesthesia alone for labor analgesia. During delivery, the serum in the second stage of labor was collected to determine the contents of pain transmitters, inflammatory cytokines and stress response indexes. Results: During delivery, serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A and group B were lower than those of group C and serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A were not significantly different from those of group B. Conclusion: 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia is with exact efficacy and good safety.展开更多

Methods: A total of 218 cases of puerperae who received caesarean section in the hospital between January 2015 and January 2017 were divided into control group (n=109) and observation group (n=109) by random table method. Control group received postpartum ropivacaine epidural analgesia alone, and observation group received postpartum ropivacaine combined with sufentanil epidural analgesia. The differences in serum levels of pain neurotransmitters, inflammatory factors and stress hormones were compared between the two groups immediately after childbirth (T0), 6 h after delivery (T1), 12 h after delivery (T2) and 24 h after delivery (T3). Results: At T0, the differences in serum levels of pain neurotransmitters, inflammatory factors and stress hormones were not statistically significant between the two groups. At T1, T2 and T3, serum NPY, β-EP and SP levels of observation group were lower than those of control group at corresponding points in time;serum IL-1β, hs-CRP and IL-6 levels of observation group were lower than those of control group at corresponding points in time;serum Cor, AngⅠ, AngⅡ and NE levels of observation group were lower than those of control group at corresponding points in time. Conclusion:Ropivacaine combined with sufentanil epidural analgesia after caesarean section can effectively inhibit the pain neurotransmitter expression and relieve the systemic inflammatory stress response in puerperae.展开更多

文摘Purpose: Levobupivacaine is thought to be a good alternative to bupivacaine for epidural labor analgesia because of its pharmacologic profile. However, the optimal concentration of levobupivacaine for labor analgesia has not been adequately studied. The objective of this retrospective study was to compare the analgesic effect of levobupivacaine between 0.06% and 0.1% both combined with 2 μg/mL of fentanyl. Methods: Primiparous women (ASA I, II) who delivered their babies to our hospital using combined spinal epidural analgesia and patient-controlled epidural analgesia between August 1, 2011 and September 30, 2011 were included into this retrospective study. The analgesic solution for epidural administration was 0.06% levobupivacaine with 2 μg/mL of fentanyl between August 1 and 31, and 0.1% levobupivacaine with 2 μg/mL of fentanyl between September 1 and 30. Their anesthetic and obstetric charts were reviewed to compare obstetric outcome, anesthetic intervention, and patients’ satisfaction. Results: There were 46 women fulfilling the inclusion criteria: 23 women in 0.06% group, and 23 women in 0.1% group. The number of patients who needed more than 3 requests for one actual bolus was significantly higher in the 0.06% group (P 0.05). Conclusion: Our results revealed that 0.06% levobupivacaine combined with 2 μg/mL fentanyl does not provide sufficient analgesic effects for epidural labor analgesia. It seems that levobupivacaine has not been adequately studied after its withdrawal from the US market. Further studies should be conducted to determine the optimal concentration of levobupivacaine for epidural labor analgesia.
文摘Childbirth experience is one of the most intense pain that majority of women will endure during their lifetime. Concerns about pain in labor remain a hot topic, and its popularity gets more common day by day as more women become aware of their rights to achieve a better quality of care during labor. There are various non-pharmacologic (transcutaneous electrical nerve stimulation, hydrotherapy, intradermal water injections and acupuncture) and pharmacologic treatments (nitrous oxide, opioids and regional analgesia techniques: spinal, epidural and combined epidural analgesia) available today. Among these, epidural analgesia offers the most effective form of pain relief and is considered to be the gold standard of labor analgesia. Despite having labor analgesic services, most women still go through painful labor due to lack of knowledge regarding it, particularly in developing countries. The main source of information regarding pain reliefs is from friends and relatives, revealing the lack of information from caregiver’s side. So this study reflects that there is a wide gap in the communication between pregnant women and obstetricians. It supports the fact that obstetricians through the practice of routinely offering labor analgesia can significantly improve the maternal and perinatal outcomes of pregnancy. Provision of standardized epidural analgesia information at an appropriate time in their pregnancy may benefit them by the practice of mutual decision-making. Thus, it may prevent women from making a difficult choice of cesarean section to avoid the fear of painful labor.
文摘Objective:To study the efficacy and safety of different doses of ropivacaine and sufentanil for epidural labor analgesia.Methods: The primiparae with single birth and cephalic presentation who underwent vaginal delivery in Chengde Maternal and Child Health Hospital between March 2015 and February 2018 were selected and randomly divided into the group A who received subarachnoid injection of sufentanil 4 μg, the group B who received injection of sufentanil 4 μg + ropivacaine 2 mg and the group C who received injection of sufentanil 4 μg+ ropivacaine 3 mg. During childbirth, serum was collected at the first, second and third stages of labor respectively to detect the secretion of pain mediators and oxidative stress mediators;after childbirth, the placenta was collected to determine the expression of stress molecules. Results: At first, second and third stages of labor, serum SP, DYN, NE, PGE2, TNF-α, COR, AT-II and MDA secretion of group B and group C were significantly lower than those of group A whereas SOD and GSH-Px secretion were significantly higher than those of group A, and serum SP, DYN, NE, PGE2, TNF-α, COR, AT-II and MDA secretion of group C were significantly lower than those of group B whereas SOD and GSH-Px secretion were significantly higher than those of group B;after childbirth, GRP78, CHOP, Bax and Caspase-3 mRNA expression in placenta of group B and group C were significantly lower than those of group A whereas Bcl-2 mRNA expression were significantly higher than that of group A, and GRP78, CHOP, Bax and Caspase-3 mRNA expression in placenta of group C were significantly lower than those of group B whereas Bcl-2 mRNA expression was significantly higher than that of group B.Conclusion: The analgesic effect of sufentanil 4 μg + ropivacaine 3 mg for epidural labor analgesia is the most significant.

文摘Objective To observe the effects of labor analgesia on maternal and neonatal outcome by epidural application of 0.125% bupivacaine combined with anisodamine on the labor stage, and modes of delivery and neonatal Apgar’s score. Methods A total of 220 primiparaes with full-term pregnancy, monocyesis and fetal head presentation without any obstetrical or systematic complications were chosen and divided into analgesic group and control group (110 in each group). The mixture of bupivacaine and anisodamine was injected into the epidural space of the parturients in the analgesic group while those patients in the control group did not receive any analgesics. Results The analgesic effect was satisfactory (91.8%), and no side effects occurred in the second stage of labor. The instrument delivery rate was lower in the analgesic group, and there was no significant difference between the two groups in neonatal Apgar’s score. Conclusion The method is feasible in clinic for labor pain relief without increasing the rate of dystocia and complications of delivery.
文摘The term “painless delivery” originated from foreign countries and has a history of more than 100 years. It is actually called “childbirth analgesia” in medicine. Labor analgesia, as its name implies, is the use of various methods to reduce or even eliminate the pain during labor. With the development of anesthesiology and pain, it has been widely used in foreign countries, especially in some developed countries in the West. The rate of labor analgesia in the United States is > 85%, and even as high as 90% in Britain. The best childbirth analgesia should include side effect is small to puerpera and fetus, exact analgesic effect, quick effect, maintain time is long, can satisfy normal labor course;puerpera is awake, can cooperate childbirth and do not affect uterine contraction, and do not affect labor course progress. In 2000, WHO proposed that medical institutions should provide various labor analgesic services for parturient women to reduce labor pain as much as possible. Encourage the use of non-pharmaceutical analgesic techniques. In this paper, the effects of different modes of labor analgesia on neonates are described as follows.
文摘Objective: To study the efficacy of low-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia. Methods: Puerperae who underwent vaginal delivery under combined spinal-epidural anesthesia for labor analgesia in Lincheng People's Hospital between June 2014 and March 2017 were selected and randomly divided into three groups, group A received 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, group B received 25 μg large-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, and group C received ropivacaine epidural anesthesia alone for labor analgesia. During delivery, the serum in the second stage of labor was collected to determine the contents of pain transmitters, inflammatory cytokines and stress response indexes. Results: During delivery, serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A and group B were lower than those of group C and serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A were not significantly different from those of group B. Conclusion: 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia is with exact efficacy and good safety.
文摘Objective To re-evaluate the systematic review of the safety and effectiveness of epidural analgesia(EA)for labor analgesia.Methods The Cochrane database,PubMed,EMBASE,EBSCO,Web of Science,ScienceDirect,China Biomedical Literature database,CNKI,Wanfang and VIP databases were searched,and the search time was limited to August 2020.Two researchers screened the literature and extracted data according to the inclusion criteria.AMSTAR was used to evaluate the methodological quality of the included studies.Pain intensity and pain relief satisfaction were used as the main indicators for re-evaluation of the effectiveness.Midwifery rate,cesarean section rate,back pain,fever,nausea and vomiting,umbilical artery pH value,and newborn Apgar score were used as the main indicators to re-evaluate the safety.Results and Conclusion A total of 9 meta-analyses were included.The safety and effectiveness of EA and opioid intravenous analgesia,acupuncture stimulation,inhalation analgesia,no analgesia,and continuous delivery were evaluated separately.The included systematic reviews showed that EA could increase the rate of device-assisted delivery,causing maternal fever,and prolonging the first and second stages of labor.But the incidence of back pain,nausea,and vomiting was lower.Therefore,analgesia had a good effect with better satisfactory degree.Current evidence shows that EA is safe and effective for labor analgesia,but the quality of the reports of current studies is not high.
文摘Objective: To study the efficacy of ropivacaine combined with sufentanil and ropivacaine alone for epidural labor analgesia. Methods: Primiparae who received vaginal delivery under epidural analgesia in Ankang People's Hospital between March 2015 and February 2017 were selected and randomly divided into accepting the group A who received ropivacaine combined with sufentanil for epidural analgesia and the group B who received ropivacaine alone for epidural analgesia. During the first, the second and the third stage of labor, the serum was collected to determine the levels of pain mediators SP, 5-HT and PGE2 as well as stress hormones NE, E, F-C, AT-II and INS;after delivery, the placenta tissue was collected to determine the expression of stress molecules GRP78, CHOP, Nrf-2 and ARE. Results: Serum SP, 5-HT, PGE2, NE, E, F-C, AT-II and INS levels of group A during the first, the second and the third stage of labor were significantly lower than those of group B;GRP78, CHOP, Nrf-2 and ARE mRNA expression in placental tissue of group A after delivery were significantly lower than those of group B. Conclusion: ropivacaine combined with sufentanil for epidural labor analgesia is more effective than ropivacaine alone in reducing pain and inhibiting stress response.
文摘Objective: To discuss the effect of ropivacaine combined with sufentanil epidural labor analgesia on pain neurotransmitters as well as cytokine production and stress hormone secretion. Methods: A total of 218 cases of puerperae who received caesarean section in the hospital between January 2015 and January 2017 were divided into control group (n=109) and observation group (n=109) by random table method. Control group received postpartum ropivacaine epidural analgesia alone, and observation group received postpartum ropivacaine combined with sufentanil epidural analgesia. The differences in serum levels of pain neurotransmitters, inflammatory factors and stress hormones were compared between the two groups immediately after childbirth (T0), 6 h after delivery (T1), 12 h after delivery (T2) and 24 h after delivery (T3). Results: At T0, the differences in serum levels of pain neurotransmitters, inflammatory factors and stress hormones were not statistically significant between the two groups. At T1, T2 and T3, serum NPY, β-EP and SP levels of observation group were lower than those of control group at corresponding points in time;serum IL-1β, hs-CRP and IL-6 levels of observation group were lower than those of control group at corresponding points in time;serum Cor, AngⅠ, AngⅡ and NE levels of observation group were lower than those of control group at corresponding points in time. Conclusion:Ropivacaine combined with sufentanil epidural analgesia after caesarean section can effectively inhibit the pain neurotransmitter expression and relieve the systemic inflammatory stress response in puerperae.
