脊柱后路内固定术后硬膜外血肿的预防与护理体会

目的 探讨脊柱后路内固定术后硬膜外血肿的预防与护理体会。方法 遵照回顾性分析法选择我院2013年2 月～2018 年2 月纳入的60 例脊柱后路内固定术患者，依照不同理疗方式进行分组。其中30 例给予常规药物治疗作为对照组，另30 例除了常规治疗之外实施综合护理作为研究组，记录两组硬膜外血肿、腰椎术后血肿及颈椎术后血肿发生率，分别在干预前后进行生活质量评分（QOL）调查，出院时发放满意度调查问卷表，对比两组干预结果。结果 研究组血肿发生率为6.67%，明显低于对照组的20.00%（P＜0.05）。干预前两组的食欲、精神、睡眠、疼痛及日常生活评分相比差异无统计学意义（P＞0.05），干预后研究组的各项评分均高于对照组（P＜0.05）。研究组对干预效果的满意度为90.00%，明显高于对照组的76.67%（P＜0.05）。结论 护理干预运用于脊柱后路内固定中效果显著，能够有效减少硬膜外血肿的发生率，提升生活质量，促进病情稳定，患者满意度较高，可维持良好医患关系。     

Intrathecal catheterisation after observed accidental dural puncture in labouring women: update of a meta-analysis and a trial-sequential analysis

BackgroundOur meta-analysis from 2013 showed that inserting a catheter intrathecally after an observed accidental dural puncture can reduce the need for epidural blood patch in labouring women requesting epidural analgesia. We updated our conventional meta-analysis and added a trial-sequential analysis (TSA).MethodsA systematic literature search was conducted to identify studies that compared inserting the catheter intrathecally with an epidural catheter re-site or with no intervention. The extracted data were pooled and the risk ratio (RR) and 95% confidence interval (95%CI) for the incidence of post-dural puncture headache (PDPH) was calculated, using the random effects model. A contour-enhanced funnel plot was constructed. A TSA was performed and the cumulative Z score, monitoring and futility boundaries were constructed.ResultsOur search identified 13 studies, reporting on 1653 patients, with a low risk of bias. The RR for the incidence of PDPH was 0.82 (95%CI 0.71 to 0.95) and the RR for the need for epidural blood patch was 0.62 (95%CI 0.49 to 0.79); heterogeneity of both analyses was high. The TSA showed that the monitoring or futility boundaries were not crossed, indicating insufficient data to exclude a type I error of statistical analysis. Contour-enhanced funnel plots were symmetric, suggesting no publication bias.ConclusionsConventional meta-analyses showed for the first time that intrathecal catheterisation can reduce the incidence of PDPH. However, TSA did not corroborate this finding. Despite increasing use in clinical practice there is no firm evidence on which to base a definite conclusion.     

全麻复合硬膜外在高龄患者腹腔镜直肠癌根治术中的应用

目的:研究全麻复合硬膜外在高龄患者腹腔镜直肠癌根治术中的应用效果。方法:选择60岁以上择期行腹腔镜直肠癌根治术患者60例,随机分为G组和GA组,每组各30例。G组患者为单纯全麻组,GA组患者为硬膜外复合全麻组。GA组患者在诱导前取L1~2硬膜外穿刺置管,予0.5%罗哌卡因5 ml,术中每小时追加5~7 ml。两组患者诱导方法相同:即,咪哒唑仑0.04 mg/kg、舒芬太尼0.3~0.4μg/kg、顺阿曲库铵0.15~0.20 mg/kg、依托咪酯0.2~0.3 mg/kg。监测并记录患者血压(BP),心率(HR),心电图(ECG),术中全麻药用量及术后患者苏醒情况。结果:GA组患者气腹后、拔管前BP、HR明显低于G组(P<0.05),且全麻药用量明显低于G组(P<0.05)。结论:全麻复合硬膜外应用于老年腹腔镜直肠癌手术较单纯全麻用药量减少,术中循环更加稳定,是腹腔镜直肠癌根治术比较安全可行的麻醉方法。     

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.     

鼻咽癌颈静脉孔侵犯的影像学表现及临床分析

[目的]探讨鼻咽癌颈静脉孔侵犯的临床和影像学特征及临床意义。[方法]回顾性分析8例初治和4例复发鼻咽癌伴颈静脉孔侵犯者的临床表现、CT及MRI特征。[结果]12例中,5例表现为Ⅸ￣Ⅺ颅神经均麻痹的颈静脉孔综合征,7例仅表现为Ⅸ颅神经麻痹。12例,有10例合并舌下神经管受累,3例有一侧的胸锁乳突肌及斜方肌萎缩,2例有一侧舌肌萎缩。CT及MRI显示鼻咽癌颈静脉孔侵犯主要有3种途径,分别为:①鼻咽病变通过茎突后间隙直接蔓延(4例,包括1例茎突后间隙复发);②转移淋巴结直接侵犯(4例,其中2例为咽后淋巴结转移,2例为颈动脉鞘淋巴结复发);③颈静脉孔骨性结构直接破坏(4例,其中1例为单纯颈静脉孔复发)。[结论]鼻咽癌可通过直接蔓延、咽后和颈动脉鞘区转移淋巴结侵犯及骨质直接破坏侵犯颈静脉孔,临床上出现Ⅸ￣Ⅺ颅神经一支或多支均麻痹。CT和MRI,尤其是MRI对于病变的诊断、病变范围的确定和放射治疗计划的制定有非常大的作用。
