The Effectiveness and Safety of Intravenous Dexmedetomidine of Different Concentrations Combined with Butorphanol for Post-Caesarean Section Analgesia: A Randomized Controlled Trial.

ABSTRACT:

Purpose

The present study aimed to determine the effectiveness of intravenous dexmedetomidine of different concentrations and to evaluate its maternal and neonatal safety when combined with butorphanol in parturients undergoing cesarean section.

Patients and methods

A total of 114 parturients between 24 and 43 years of age, with singleton pregnancy who underwent elective cesarean section under epidural anesthesia, were randomly allocated to four groups: group C received 0.9% sodium chloride after delivery, followed by butorphanol (3 ?g·kg^-1·h^-1); patients in groups D1, D2, and D3 received 0.5 ?g·kg^-1·h^-1 dexmedetomidine after delivery, followed by butorphanol (3 ?g·kg^-1·h^-1) combined with dexmedetomidine 0.03, 0.05, and 0.08 ?g·kg^-1·h^-1, respectively. The primary outcome was the visual analogue scale (VAS) score at 6 h after delivery when patients were at rest. Secondary outcome measures included VAS after delivery when patients were on movement and uterine cramping, Ramsay sedation scale (RSS), relative infant dose (RID) of dexmedetomidine, satisfaction with analgesia after surgery and symptoms of CNS depression in neonates.

Results

There were no significant differences in patient characteristics among the groups (P > 0.05). The VAS at all timepoints after delivery in groups D2 and D3 were significantly lower than in groups C and D1 (P < 0.001). RSS scores were clearly higher in group D3 than in the other three groups at 6 h and 12 h (P < 0.0001). RID in groups D1, D2, and D3 was 0.171%, 0.197%, and 0.370%, respectively. Compared with group D1, RID was higher in group D3 (P = 0.0079). Degree of satisfaction with analgesia was higher in groups D2 and D3 (P < 0.005).

Conclusion

Continuous intravenous infusion of 0.05 ?g·kg^-1·h^-1 dexmedetomidine combined with 3 ?g·kg^-1·h^-1 butorphanol could be safely applied in healthy parturients with satisfactory analgesia after cesarean section without changes in sedation.

Project description:BackgroundPost-caesarean section analgesia is important physiologically and psychologically for both mothers and infants. Patient-controlled analgesia is a well-established method of administering opioids for postoperative pain. However, to date, no study has systematically investigated the effects of opioids administered through intravenous patient-controlled analgesia (IVPCA) or patient-controlled epidural analgesia (PCEA) in parturients who have undergone caesarean section.MethodsThis systematic review and network meta-analysis aimed to evaluate the analgesic and adverse effects of opioids administered via IVPCA or PCEA in parturients who have undergone a caesarean section. PubMed, Embase, Scopus, Web of Science, and Cochrane Library were searched from inception through 02 10, 2022 for relevant records. Randomised controlled trials (RCTs) that compared opioids administered via IVPCA or PCEA and reported outcomes of interest were included. Studies were excluded if the solution for patient-controlled analgesia contained antiemetics and/or other analgesics in addition to opioids. The methodological quality of RCTs was assessed using the revised Cochrane Risk of Bias Tool. Summary data were extracted from each eligible study. The primary outcome was pain intensity, and the secondary outcomes were opioid-related adverse effects. Frequentist network meta-analyses were performed using a contrast-based random-effects model. This study is registered with PROSPERO, CRD42021254040.FindingsTwenty-three studies with 2589 parturients were included. Compared with IVPCA morphine as a reference treatment, PCEA fentanyl had better analgesic effects at 4 h (mean difference [MD] in the visual analogue scale score, -0.75; 95% confidence interval [CI] [-1.16, -0.34]) and 8 h (MD, -0.93; 95% CI [-1.57, -0.28]) and yielded lower odds of developing nausea/vomiting (odds ratio [OR], 0.27; 95% CI [0.09, 0.80]) and sedation/drowsiness (OR, 0.22; 95% CI [0.11, 0.45]). However, PCEA fentanyl may be more likely to cause pruritus than IVPCA treatments.InterpretationConsidering the analgesic efficacy; opioid-induced nausea, vomiting, and sedation; and the well-being of breastfed infants, PCEA fentanyl may be the treatment of choice for post-caesarean section analgesia.FundingThe Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation (TCRD-TPE-111-27).

Project description:BackgroundThe OptiBIRTH study incorporates a multicentre cluster randomised trial in 15 hospital sites across three European countries. The trial was designed to test a complex intervention aimed at improving vaginal birth after caesarean section (VBAC) rates through increasing women's involvement in their care. Prior to developing a robust standardised model to conduct the health economic analysis, an analysis of a hypothetical cohort was performed to estimate the costs and health effects of VBAC compared to elective repeat caesarean delivery (ERCD) for low-risk women in four European countries.MethodsA decision-analytic model was developed to estimate the costs and the health effects, measured using Quality Adjusted Life Years (QALYs), of VBAC compared with ERCD. A cost-effectiveness analysis for the period from confirmation of pregnancy to 6 weeks postpartum was performed for short-term consequences and during lifetime for long-term consequences, based on a hypothetical cohort of 100,000 pregnant women in each of four different countries; Belgium, Germany, Ireland and Italy. A societal perspective was adopted. Where possible, transition probabilities, costs and health effects were adapted from national data obtained from the respective countries. Country-specific thresholds were used to determine the cost-effectiveness of VBAC compared to ERCD. Deterministic and probabilistic sensitivity analyses were conducted to examine the uncertainty of model assumptions.ResultsWithin a 6-week time horizon, VBAC resulted in a reduction in costs, ranging from €3,334,052 (Germany) to €66,162,379 (Ireland), and gains in QALYs ranging from 6399 (Italy) to 7561 (Germany) per 100,000 women birthing in each country. Compared to ERCD, VBAC is the dominant strategy in all four countries. Applying a lifetime horizon, VBAC is dominant compared to ERCD in all countries except for Germany (probabilistic analysis, ICER: €8609/QALY). In conclusion, compared to ERCD, VBAC remains cost-effective when using a lifetime time.ConclusionsIn all four countries, VBAC was cost-effective compared to ERCD for low-risk women. This is important for health service managers, economists and policy makers concerned with maximising health benefits within limited and constrained resources.
