Purpose To investigate the effectiveness of sufentanil patient-controlled intravenous analgesia pump (PCIA) and background infusion in patients of post-cesarean analgesia. Patients and Methods This trial compared two groups of women undergoing cesarean section and receiving PCIA: no background infusion group (n=30), 6-min lockout time, and background infusion group (n=30), 2 mL/h infusion, 10-min lockout time. Both groups with 2 μg/kg sufentanil was diluted to 100 mL with normal saline. VAS scores at rest at 36 h was the primary endpoint. The secondary endpoints were the VAS scores at rest at 6, 12, and 24 h, the total amount of sufentanil consumed, the Ramsay sedation score (RSS) assessed at the same time points, postpartum bleeding within 24 h, the injection/attempt (I/A) ratio, BP and HR, PONV, side effects of sufentanil. Results Compared with the no background infusion group, the background infusion group showed lower VAS pain scores at 6, 12, and 24 h (P<0.01), but no differences at 36 h (95% CI = −0.5–0.8. P>0.05). Attempts, injections, and total sufentanil consumption were significantly different between the two groups (P<0.001), but without difference in I/A. Bleeding was less in the background infusion group at 1 h (P=0.03). The minimal respiration rates were not significantly different between groups. Conclusion Background infusion increased the total consumption of sufentanil within 36 h after cesarean section. Although it did not reduce uterine contraction pain and wound pain at 36 h, it significantly reduced the pain at 6, 12, and 24 h after cesarean section. It improved patient satisfaction and reduced the amount of bleeding after 1 h. Importantly, it did not increase the incidence of hypertension, PONV and respiratory depression.
Background: Patient-controlled analgesia (PCA) is an effective method of postoperative pain, there have been many studies performed that have compared the efficacy of hydromorphone with continuous sufentanil. The purpose of this systematic review is to compare the efficacy and safety of hydromorphone and sufentanil.Methods: Seven databases were searched for controlled trials to compare the efficacy and safety of hydromorphone and sufentanil. After selecting the studies, extracting the data, and assessing study quality, the meta-analysis was performed on several of the studies with RevMan 5.3.Results: Thirteen studies comprised of 812 patients were found. The pain intensity of the hydromorphone group was significantly lower than that of the sufentanil group at 12 hours. With no statistical difference at 24 to 48 hours (MD 12 = À1.52, 95% CI [À2.13, À1.97], P <.05). The sedation intensity of the hydromorphone group at 12, 24, and 48 hours were lower than those of the sufentanil group, with no statistical difference (MD 12 = À0.03, 95% CI [À0.18, 0.12], P > .05; MD 24 = À0.20, 95% CI [À0.42, 0.03], P > .05; MD 48 = À0.03, 95% CI [À0.18, 0.11)], P > .05). The PCA requests in the hydromorphone group were less than that in the sufentanil group, and there was no significant difference (RR = À0.20, 95% CI [À1.93,1.53], P > .05). The incidence of adverse events in the hydromorphone group was less than that in the sufentanil group, and there was a statistical difference: (RR = 0.61, 95% CI [0.47,0.79], P < .05). Conclusion:Compared with sufentanil, PCA with hydromorphone was more effective in relieving pain and PCA requests 12, 24, and 48 hours after operation, and significantly reduced the incidence of adverse events, but it did not have an advantage in sedation intensity.Abbreviations: PCA = patient-controlled analgesia, PCIA = intravenous PCA, RCTs = randomized controlled trials, VAS = Visual Analogue Scale.
This study aims to demonstrate current research priorities and predict future trends in the link between kidney disease and gut microbiota by means of scientometric analysis. We collected nearly 20 years (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020) of publications related to kidney disease and gut microbiota in the Web of Science database. CiteSpace was used to evaluate the knowledge mapping. There are 965 manuscripts about kidney disease and gut microbiota in total, and faster growth after 2016. The country, institution, and author who posted the most are the USA, Univ Calif Irvine, and DENISE MAFRA, respectively. The frequencies are 109, 16, and 17. The most important of them are FRANCE (0.23), Fed Univ Parana UFPR (0.13), and VAZIRI ND (1.14), owing to their highest centrality. In addition, the cited documents that have contributed the most to the co-citations are Wong J (2014); the most key cited reference is Rossi M (2016); the most commonly used keywords are chronic kidney disease, gut microbiota and indoxyl sulfate. Through scientometric analysis of the past 20 years, we obtained the knowledge map of this information, which has important guiding significance for accurately and quickly locating trends in this field.
Purpose: Patient-controlled intravenous analgesia (PCIA) is an option for pain cesarean section analgesia. However, the effect of a background infusion on the analgesic requirements of parturients is still debated. In order to attempt to identify the optimal cesarean section analgesia infusion regime, we evaluated the benefit of the background infusion in this randomized study.Patients and methods: 60 Parturients had a PCIA analgesia protocol initiated consisting of a 0.5mL bolus, and compared 2 Groups: no background infusion, 6 min lockout time (Group A). 2 mL/h infusion, 10 min lockout time (Group B). The total amount of sufentanil consumed, two categories of pain scores, sedation score, postpartum hemorrhage, Injection/attempt (I/A) ratio, side effects, satisfaction were calculated for both groups.Results: Group B significantly reduce visual analog scale(VAS)pain scores 6, 12h. Group A and Group B were not significantly different regarding wound pain at rest (VAS-R) and uterine cramping pain (VAS-U) at postoperative 24, 36 hours. In terms of I/A, Group A was lower than Group B, there was no significant difference. Group B showed significantly higher satisfaction than Group A. Total consumption of sufentanil at 36 hours postoperative was much greater in Group B. Group B can significantly reduce the postpartum hemorrhage within 1 hour. The minimal respiration rates were not significantly different among groups. The side effect were not observed among groups. All parturients had the same Ramsey sedation score.Conclusion: In comparison with the without background infusion, total consumption of sufentanil at 36 hours postoperative was much greater in the background infusion, but it can significantly reduce the uterine contraction pain and wound pain of 12 hours after cesarean section, significantly improve patient satisfaction, reduce the postpartum hemorrhage within 1 hour, and does not increase the incidence of PONV and respiratory depression in parturients.
