  • Anesthesia management of pregnancy with moderate to severe scoliosis

    Objective To discuss the characteristics of delivery and anesthesia management of pregnant women with moderate to severe scoliosis, and to summarize the anesthesia implementation strategies for pregnant women with scoliosis. Methods Pregnant women with moderate to severe scoliosis admitted to West China Second University Hospital, Sichuan University between January 2020 and January 2022 were retrospectively included. The demography information, delivery mode, anesthesia implementation plan and other relevant data of the women were analyzed. Results A total of 9 women with moderate to severe scoliosis were included, with an average age of 29.9 years. The median (lower quartile, upper quartile) of the Cobb angle of the women was 42° (35°, 54°). There were 5 women with moderate to severe impairment of lung ventilation function, 1 woman with grade Ⅲ heart function, and 8 women with comorbidities. Among the 8 women who underwent cesarean section, 3 underwent general anesthesia, 4 underwent epidural block, and 1 underwent local anesthesia with enhanced sedation. One woman who chose vaginal delivery underwent epidural labor analgesia. All women passed the surgery or delivery period safely, with 5 transferred to the intensive care unit for further treatment after surgery, and 4 safely returned to the ward after surgery. All women recovered and were discharged. Eight fetuses survived, and 1 fetus underwent lethal induced abortion. Conclusions Pregnant women with moderate to severe scoliosis during pregnancy have poor tolerance to vaginal delivery due to severe malformations and organ dysfunction, especially cardiopulmonary dysfunction. Most of them terminate pregnancy through cesarean section. When making anesthesia decisions, it is important to carefully consider the women’s own condition and surgical risks.

  • Local versus Systemic Application of Opioids for Labor Analgesia: A Systematic Review

    Objective To assess the effectiveness and safety of local versus systemic application of opioids for labor analgesia. Methods We searched PubMed (1966 to January 2008), EMBASE (1980 to January 2008), The Cochrane Library (Issue 1, 2008), CBM (1978 to January 2008), CNKI (1979 to January 2008) for randomized controlled trials (RCTs) involving local versus systemic application of opioids for labor analgesia. Quality assessment and data extraction were conducted by two reviewers independently. Meta-analyses were conducted with The Cochrane Collaboration’s RevMan 4.2.10 software. Results A total of 12 trials involving 5909 participants met the inclusion criteria. Meta-analyses showed that local application of opioids was superior to systemic application in terms of maternal satisfaction with pain relief during labor (RR 1.63, 95% CI 1.27 to 2.09). No significant difference was found between the two groups in the incidence of low neonatal Apgar score at 5 minutes (RR 0.63, 95% CI 0.40 to 1.01). Conclusion Local application of opioids for labor analgesia appears to be more effective than systematic use in reducing pain during labor. But as for safety concerns, maternal and neonatal adverse effects are observed in both groups. Thus, more high-quality and large-scale RCTs are needed.

  • Clincal Evidence of Analgesia During Labor

    Objective To assess the effects on labour, maternal, and neonatal outcomes of different techniques and drugs for analgesia during labour. Methods We searched The Cochrane Library (Issue 4, 2006) , MEDLINE (Jan. 1978 to Oct. 2006) and CBMdisc (Jan. 1980 to Oct. 2006) to collect the current best evidence of labor analgesia. Results We included eight Cochrane systematic reviews and six other meta-analyses. The evidence showed that epidural analgesia was associated with a longer second stage of labour, more frequent oxytocin augmentation, higher incidence of instrumental vaginal delivery and maternal fever. But it was unlikely to increase the risk of caesarean section. Conclusion Epidural analgesia is superior to other approaches.

  • Methodological Evaluation of Clinical Randomized Controlled Trials in Clinical Anesthesiology

    Objective To evaluate the current situation of the design of the randomized controlled trials (RCTs) in Clinical Anesthesiology, Chinese Journal of Anesthesiology and Chinese Journal of Pain Medicine from 1999 to September in 2003. Method The clinical therapeutic studies in the three journals from 1999 to September of 2003 were hand searched over page by page to identify strictly the randomized controlled trials according to Chinese Cochrane Center hand search guideline. Results 412, 378 and 142 papers of the three journals were published, among which, there were 237, 221 and 68 papers of RCT. Conclusions Although the quality of RCT in the three journals has been increased significantly year by year, but there still exist some problems. The quality of RCT papers needs more improvement to guarantee RCT to be more precise as it demands.

  • The association between the variants of HNF1B gene and the risk of prostate cancer: a meta-analysis

    ObjectivesTo systematically review the association between the variants of HNF1B gene and the risk of prostate cancer.MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM and WanFang Data databases were electronically searched to collect case-control studies on the association between the variants of HNF1B gene and risk of prostate cancer from inception to December, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 14.0 software.ResultsA total of 15 case-control studies involving 30 532 patients and 38 832 controls were included. The results of meta-analysis showed that: there was a strong significant association between rs4430796 variants (Gvs.A: OR=0.802, 95%CI 0.784 to 0.821, P<0.001; GGvs.AA: OR=0.659, 95%CI 0.606 to 0.717, P<0.001; AGvs.AA: OR=0.762, 95%CI 0.714 to 0.814, P<0.001), rs11649743 variants (Avs.G: OR=0.875, 95%CI 0.820 to 0.941, P<0.001; AAvs.GG: OR=0.669, 95%CI 0.564 to 0.792, P<0.001; AGvs.GG: OR=0.855, 95%CI 0.798 to 0.916, P<0.001), rs7501939 variants (Avs.G: OR=0.833, 95%CI 0.807 to 0.859, P<0.001), rs3760511 variants (Avs.C: OR=0.834, 95%CI 0.803 to 0.868, P<0.001) and risk of prostate cancer.ConclusionsCurrent evidence shows that HNF1B gene variants are associated with risk of prostate cancer. Due to limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.

  • Efficacy of dexmedetomidine for controlled hypotension in orthognathic surgery: a systematic review

    ObjectiveTo systematically review the efficacy of dexmedetomidine for controlled hypotension in orthognathic surgery. MethodsThe PubMed, Embase, Cochrane Library, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on dexmedetomidine for controlled hypotension in orthognathic surgery from inception to May, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 8 RCTs involving 371 patients were included. The results of meta-analysis showed that the operation time of dexmedetomidine group was not significantly different from that of hypotensive drug group, but was shorter than that of saline group (MD=−23.20, 95%CI −44.05 to −2.35, P=0.03). There were no statistically significant differences in the mean arterial pressure and the intraoperative blood loss between dexmedetomidine group and the control group. Compared with those in the control group, the heart rate (MD=−18.78, 95%CI −30.80 to −6.77, P=0.002) and the incidence of postoperative adverse events (OR=0.25, 95%CI 0.08 to 0.76, P=0.01) in dexmedetomidine group were less than those in the control group significantly. ConclusionCurrent evidence shows that dexmedetomidine can be used effectively for controlled hypotension in orthognathic surgery. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusion.

  • Effect of preload versus coload on reducing the incidence of spinal anesthesia-induced hypotension during cesarean section: a Meta-analysis

    ObjectiveTo evaluate the effect of different rehydration strategies on the incidence of spinal anesthesia-induced hypotension and neonatal outcomes during elective cesarean section.MethodsWe searched PubMed, Embase, the Cochran Library, China National Knowledge Internet, VIP database, Wanfang database, and China Biology Medicine database from inception to January 2018, to collect randomized controlled trials (RCTs) about the incidence of spinal anesthesia-induced hypotension during elective cesarean section and neonatal outcomes of preloading or coloading. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the study. Meta-analysis was conducted using RevMan 5.3 software.ResultsA total of 11 RCTs were included, including 894 parturients, of whom 448 cases in the preload group and 446 cases in the coload group. Comparing with the preload group, the incidence of spinal anesthesia-induced hypotension during cesarean section in the coload group significantly decreased [risk ratio (RR)=1.27, 95% confidence interval (CI) (1.13, 1.43), P<0.000 1]. Subgroup analysis showed that in the crystalloid fluid group, the difference in the incidence of hypotension between the preload group and the coload group was statistically significant [RR=1.48, 95%CI (1.26, 1.73), P<0.000 01]; while in the colloidal fluid group, the difference in the the incidence of hypotension between the preload group and the coload group was not significant [RR=1.00, 95%CI (0.85, 1.17), P=0.96]. The lowest systolic blood pressure, the incidence of nausea and vomiting, and neonatal outcomes had no significant difference between the two groups.ConclusionsComparing with preloading crystalloid fluid, rapid infusion of crystalloid fluid at the same time implementation of spinal anesthesia could significantly reduce the incidence of hypotension during cesarean section while there was no superiority in infusion of colloid fluid. There was no significant effect on the severity of hypotension, nausea and vomiting, and neonatal outcomes. Due to the limitation of the quantity and quality of the included studies, the above conclusions need to be verified by more high-quality studies.
