Advances in epidural labor analgesia:Effectiveness and treatment strategies of butorphanol

In this editorial,we provide a critical review of the article by Tang et al published in the World J Clin Cases,focusing on the utilization of butorphanol for epidural analgesia during labor.Our discussion encompasses recent research developments in epidural labor analgesia,specifically highlighting the current status of clinical applications of butorphanol and associated treatment approaches.Epidural analgesia is widely acknowledged as the primary method for pain management during labor,offering effective and prolonged pain relief while allowing mothers to remain alert and actively participate in the delivery process.Among the various drugs utilized for epidural labor analgesia,butorphanol has received increasing attention due to its potential efficacy and distinctive pharmacological properties.As a synthetic opioid analgesic,butorphanol exhibits both agonistic and antagonistic activity on opioid receptors,striking a balance between analgesia and minimizing side effects.Nevertheless,the safety and efficacy of butorphanol in epidural labor analgesia remains controversial.While certain studies have reported positive outcomes with butorphanol,including effective pain relief and a reduced incidence of side effects,others have raised concerns about its safety and efficacy compared to traditional opioids or alternative analgesics.In addition,the optimal dosing strategy and regimen of butorphanol as an adjuvant in epidural labor analgesia still need to be verified.Through comprehensive synthesis and analysis of existing literature,we aim to evaluate the current evidence regarding the use of butorphanol for epidural labor analgesia,delineate areas of consensus and controversy,and propose future avenues for research and clinical practice in this domain.

Effects of combined spinal-epidural anesthesia on anxiety,labor analgesia and motor blocks in women during natural delivery

BACKGROUND The background of this study was analgesia in natural delivery.The combined spinal-epidural anesthesia has obvious analgesic effect on the parturients in natural labor,and combined spinal-epidural anesthesia has been widely used in anesthesia for various diseases.AIM To study the effects of combined spinal-epidural anesthesia on anxiety,labor analgesia,and motor blocks in parturients during natural delivery.METHODS A total of 120 women who gave birth at Changning District Maternal and Child Health Hospital between December 2021 to December 2022 were included;a random number table approach was employed to divide the women into a control group and a joint group,with each group consisting of 60 women.The control group was given epidural anesthesia,while the joint group was given combined spinal-epidural anesthesia.The visual analog scale(VAS)was used to evaluate the degree of maternal pain.Comparisons were made between the two groups’conditions of childbirth and the duration of labor.Apgar scores were used to evaluate the status of the newborns at birth;Self-rating Anxiety Scale(SAS)and General Self-Efficacy Scale(GSES)scores,umbilical artery blood gas analysis indices and stress indices were compared between the two groups;and the frequencies of motor block and postpartum complications were analyzed.RESULTS In comparison to the control group,in the joint group,the VAS scores for the first,second,and third stages of labor were lower(P<0.05).The rates of conversion to cesarean section and postpartum blood loss in the joint group were lower than those in the control group(P<0.05).No significant differences were observed in the Apgar score,the duration of the first stage of labor,or the total duration of labor between the two groups(P>0.05).The second and third stages of labor in the joint group were shorter than those in the control group(P<0.05).When compared to the control group,the postpartum SAS score of the joint group was lower,while the GSES score was greater(P<0.05).Between the control group and the joint group,the differences observed in pH,arterial carbon dioxide partial pressure,arterial oxygen partial pressure,or arterial hydrogen ion concentration were not significant(P>0.05).Nitric oxide,cortisol,and adrenaline levels were lower in the joint group than in the control group(P<0.05).There were no substantial differences in Bromage grade or rate of complications between the two groups(P>0.05).CONCLUSION For parturients during natural delivery,combined spinal-epidural anesthesia can reduce anxiety,provide labor analgesia,shorten labor time,and reduce postoperative stress levels but did not result in a motor block.

Preprocedure ultrasound imaging combined with palpation technique in epidural labor analgesia

BACKGROUND For parturients with paroxysmal uterine contraction pain,rapid analgesia is needed.We used preprocedure ultrasound imaging combined with the palpation technique in epidural analgesia for labor,and evaluated the usefulness of this technique in epidural labor analgesia.AIM To evaluate the usefulness of preprocedure ultrasound imaging in epidural analgesia for labor.METHODS In this prospective randomized observational study,72 parturients were assigned to two groups(combined or palpation group).The target interspace of all parturients was first identified by the palpation technique.Then in the combined group,preprocedure ultrasound imaging was used before epidural puncture.In the palpation group,only the traditional anatomical landmarks technique(palpation technique)was performed.The primary outcome was total duration of the epidural procedure(for the ultrasound group,the duration of the preprocedure ultrasound imaging was included).The secondary outcomes were the number of skin punctures,the success rate at first needle pass,the number of needle passes,the depth from the skin to epidural space,and the complications of the procedure.RESULTS Total duration of the epidural procedure was similar between the two groups(406.5±92.15 s in the combined group and 380.03±128.2 s in the palpation group;P=0.318).A significant improvement was demonstrated for epidural puncture and catheterization in the combined group.The number of needle passes was 1.14 in the combined group and 1.72 in the palpation group(P=0.001).The number of skin puncture sites was 1.20 in the combined group and 1.25 in the palpation group(P=0.398).The success rate at first needle pass was 88.89%in the combined group and 66.67%in the palpation group(P=0.045).CONCLUSION This study demonstrated that the total duration of epidural procedures with preprocedure ultrasound imaging combined with the palpation technique was not longer than the traditional anatomical landmarks technique,which were performed by six experienced anesthesiologists in parturients with normal weights undergoing labor analgesia.

Effects of Ropivacaine-sufentanil Epidural Analgesia on Labor and Maternal and Neonatal Outcomes

[Objectives]This study aimed to investigate the effects of ropivacaine-sufentanil epidural analgesia on labor and maternal and neonatal outcomes.[Methods]A total of 180 primiparas in full-term pregnancy were selected.They were randomly divided into treatment group(n=90)and control group(n=90).The primiparas in the treatment group were injected epidurally with ropivacaine and sufentanil for analgesia,and the primiparas in the control group were subjected to vaginal delivery.The VAS scores at 5,10,30 and 60 min of analgesia were observed.The vaginal bleeding amount,total labor duration,neonatal Apgar score and vaginal delivery rate of the two groups were compared.[Results]Compared with the control group,the VAS score in the treatment group differed insignificantly after 5 min of analgesia(P>0.05),and decreased significantly after 10,30 and 60 min of analgesia(P<0.05).The vaginal bleeding amount of the treatment group was significantly smaller than that of the control group(P<0.05).There was no significant difference in the neonatal Apgar score between the two groups(P>0.05).In the treatment group,the vaginal delivery rate increased(P<0.05),the second stage of labor was prolonged(P<0.05),and the first and third stages of labor did not change significantly(P>0.05).[Conclusions]Epidural analgesia with ropivacaine and sufentanil has a good analgesic effect and good safety,and is worthy of clinical promotion.

Women’s Awareness and Attitudes towards Labor Analgesia Influencing Practice between Developed and Developing Countries

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.

Comparison between 0.06% and 0.1% Levobupivacaine Combined with 2 μg/mL of Fentanyl for Epidural Labor Analgesia

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.

Effects of labor analgesia on maternal and neonatal outcome by epidural low concentration of bupivacaine combined with anisodamine

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.

Effects of Different Modes of Labor Analgesia on Neonatal Neurobehavior

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.

A systematic Review of the Safety and Effectiveness of Epidural Analgesia for Labor Analgesia

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.
