腰硬联合镇痛及患者自控镇痛对产程及分娩结局的影响

目的 探讨腰硬联合(CSEA)及患者自控镇痛(PCEA)对产程及分娩结局的影响。方法 随机选取2014年1~12月足月待产、无妊娠合并症和并发症初产妇996例,其中503例产妇于活跃期实施CSEA+PCEA镇痛(分娩镇痛组),493例未行分娩镇痛(对照组),分别记录并比较两组产妇各产程时间、子宫收缩、镇痛效果、运动神经阻滞程度、产程中缩宫素的使用率、产后出血率、羊水Ⅲ度污染率、新生儿Apgar评分、产钳助产和剖宫产率。结果 分娩镇痛组第一产程、第二产程较对照组有所延长,差异有统计学意义(P<0.05);第三产程无明显改变;子宫收缩力减弱;分娩镇痛组较对照组镇痛效果显著,差异有统计学意义(P<0.05);运动阻滞程度低;缩宫素使用率、产后出血率、羊水Ⅲ度污染率、及新生儿Apgar评分及产钳助产和剖宫产率两组比较,差异均无统计学意义(P>0.05)。结论 腰硬联合分娩镇痛可能会使第一产程、第二产程延长,对子宫收缩力有一定的影响,但并未增加缩宫素的使用率及产钳助产和剖宫产率,其镇痛效果显著,运动阻滞程度低,对分娩结局无不良影响。     

Protocol for the development of consensus-based clinical case reporting guideline extension: CARE for acupuncture

BackgroundHealth research reporting guidelines for case reports (CARE - CAse REport) published in 2013 and 2017 have become a generally accepted standard for publishing case reports. The CARE guidelines represent an architectural framework for writing an evidence-based case report that can be customized as need for a specialty (or disease) if needed. We aim to develop a CARE guideline extension for acupuncture following the EQUATOR Network (Enhancing the QUAlity and Transparency Of health Research) and the 2010″Guidance for Developers of Health Research Reporting". We have established a group of international experts including; clinicians, researchers and methodologists. We performed a needs assessment based on a review of acupuncture case reports published in the indexed medical literature. The needs assessment will be followed by (1) a series of expert interviews to establish a draft, (2) a modified Delphi process, and (3) a consensus meeting. Following the consensus meeting we will pilot test the CARE draft before publishing the CARE extension for acupuncture.MethodsWe will develop the CARE extensions for acupuncture following recommendations of the EQUATOR Network and the 2010 "Guidance for Developers of Health Research Reporting". We will establish an international multidisciplinary group including clinical practitioners, acupuncturists, researchers of reporting guidelines on acupuncture, clinical epidemiologists and statisticians.We performed a needs assessment, reviewing published case reports using acupuncture as a therapeutic intervention from indexed medical journals (PubMed-PMC and Medline, Scopus, Embase, the Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Wan Fang database, Chinese BioMedicine database (CBM), China National Knowledge Infrastructure (CNKI), and VIP). In consultations with advisors we will develop a draft of potential items to be included in the CARE extension for acupuncture. Then we will conduct a modified Delphi process of at least three rounds, hold a face-to-face consensus meeting, pilot test and submit the CARE extension for acupuncture for publication.ConclusionThe development of a widely accepted CARE extension for acupuncture for case reports published in indexed medical journals. These guidelines will follow the EQUATOR Network recommendations and the 2010 "Guidance for Developers of Health Research Reporting".     

Gd-EOB-DTPA增强MRI评估功能性肝体积与肝功能Child-Pugh分级的相关性

目的：对比解剖性肝脏体积（ALV）和功能性肝脏体积（FLV）与肝功能Child-Pugh分级的相关性。方法：选择温州医科大学附属第二医院育英儿童医院2014年1月至2019年4月同时行增强CT和Gd-EOB-DTPA增强MRI扫描的肝硬化患者25例。对所有患者进行肝功能Child-Pugh评分，检测所有入组患者每个肝段的Gd-EOB-DTPA增强MRI平扫期和肝胆特异期的信号对比增强率（CER），以CT扫描的数据为基础利用MI-3DVS计算每个肝段的ALV和全肝的FLV。分析ALV和FLV与肝功能Child-Pugh分级的相关性。结果：肝功能Child-Pugh分级与ALV呈负相关（r=-0.792，P＜0.001），曲线拟合的决定系数（R2）=0.63；肝功能Child-Pugh分级与FLV亦呈负相关（r=-0.911，P＜0.001），曲线拟合的R2=0.80。FLV与肝功能Child-Pugh分级有更显著的负相关性。结论：结合Gd-EOB-DTPA增强MRI平扫期和肝胆特异期的信号CER和ALV计算所得的FLV较ALV能更好地反映肝脏的功能状态。     

罗哌卡因联合舒芬太尼在剖宫产术后镇痛中的临床效果分析

目的：探讨罗哌卡因联合舒芬太尼在剖宫产术后镇痛中的临床疗效。方法方便选取2014年3月—2015年3月该院麻醉科收诊的剖宫产产妇60例,随机法分为观察组及对照组各30例,对照组术后给予罗哌卡因联合吗啡镇痛治疗,观察组术后给予罗哌卡因联合舒芬太尼镇痛治疗,记录并分析两组产妇镇痛效果。结果观察组术后2h、8h、12 h、24 hVAS评分分别为(1.98±0.81)分、(2.28±0.78)分、(1.66±0.67)分、(1.17±0.61)分,均低于对照组(3.51±1.07)分、(3.82±1.03)分、(3.24±0.95)分、(2.16±0.55)分,且差异具有统计学意义(P<0.05)；观察组术后肌力恢复正常时间和肛门排气时间分别为(7.28±1.16)h、18.49±1.71)h,均低于对照组(15.67±3.59)h、20.84±2.10)h,且差异有统计学意义(P<0.05)；③观察组产妇术后不良反应发生率为6.67%,显著低于对照组26.67%,且差异具有统计学意义(P<0.05)；结论罗哌卡因联合舒芬太尼在剖宫产术后镇痛中的效果优于罗哌卡因联合吗啡,不良反应低,能有效缓解孕妇术后疼痛。     

Dural puncture epidural versus conventional epidural block for labor analgesia: a systematic review of randomized controlled trials

IntroductionDural puncture epidural (DPE) analgesia is a modification of conventional epidural analgesia that involves the intentional puncture of the dura with a spinal needle through the needle placed in the epidural space, without a medication being injected intrathecally. There have been contradictory findings regarding better analgesia and better block quality.MethodsA systematic literature search was done to identify randomized controlled trials (RCT) comparing DPE with epidural analgesia. The risk of bias was assessed with the Cochrane tool. Risk ratio and 95% confidence intervals were calculated.ResultsFive RCTs including 581 patients were identified. One RCT on caesarean section was excluded. Single studies suggested slightly better analgesia by finding a median time to achieve sufficient analgesia of two minutes less in the DPE group, a higher number of women having a pain score <10/100 at 20 min, a reduction in the number of epidural top-ups and better sacral spread. The studies did not show a difference between DPE and epidural analgesia for catheter replacement or manipulation rates, the incidence of intravascular placement or unilateral block.ConclusionThere is a lack of clear evidence on either the benefits or the risks of the DPE technique, such that a recommendation for or against its routine use is premature. Two of the three studies showing a beneficial effect of DPE came from the same institution and replication of the findings by other groups is warranted.     

Elective Nodal Irradiation for Limited-stage Small-cell Lung Cancer: Survey of US Radiation Oncologists on Practice Patterns

BackgroundTraditionally, elective nodal irradiation (ENI) has been used in clinical trials that have established thoracic radiotherapy as instrumental in improving survival for patients with limited-stage small-cell lung cancer (LS-SCLC). However, several reports have suggested that the omission of ENI might be appropriate. Current US practice patterns are unknown regarding ENI for patients with LS-SCLC.Materials and MethodsWe surveyed US radiation oncologists via an institutional review board-approved questionnaire. The questions covered demographics, treatment recommendations, and self-assessed knowledge of key clinical trials. χ² and Cochran-Armitage tests were used to evaluate for statistically significant correlations between responses.ResultsWe received 309 responses. Of the respondents, 21% recommended ENI for N0 LS-SCLC, 29% for N1, and 30% for N2; 64% did not recommend ENI for any of these clinical scenarios. The respondents who recommended ENI were more likely to have been practicing for > 10 years (P < .001), more likely to be in private practice (P = .04), and less likely to be familiar with the ongoing Cancer and Leukemia Group B 30610 trial (P = .04). Almost all respondents (93%) prescribed the same radiation dose to the primary disease and involved lymph nodes. When delivering ENI, 36% prescribed the same dose to the involved and elective nodes, and 64% prescribed a lower dose to the elective nodes.ConclusionNearly two thirds of respondents did not recommend ENI, which represents a shift in practice. A recent large clinical trial that omitted ENI reported greater overall survival than previously reported and lower-than-expected radiation toxicities, lending further evidence that omitting ENI should be considered a standard treatment strategy.
