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.

A Very Long-term Longitudinal Study on the Evolution and Clinical Outcomes of Persistent Iatrogenic Atrial Septal Defect After Cryoballoon Ablation

Background

Persistent iatrogenic atrial septal defect (iASD) is a common but poorly characterized complication after cryoballoon (CB) pulmonary vein isolation (PVI) procedures. We therefore investigate its prevalence, evolution, risk factors, and clinical outcomes in a prospective longitudinal study.

Therapeutic effects of topical 0.03% Tacrolimus ointment in children with refractory vernal keratoconjunctivitis in Middle East

ObjectiveThe purpose of this paper is to review the efficacy and safety profile in children treated with topical 0.03% Tacrolimus ointment for vernal keratoconjunctivitis in Middle East and to propose a treatment posology. According to recent studies, a complex non-IgE dependent mechanism plays a relevant role in the pathogenesis of vernal keratoconjunctivitis. Numerous cells and mediators have been found in the serum, conjunctiva and tears of patients with Vernal keratoconjunctivitis.DesignThis case series included 10 patients from a single centre, pediatric department of a tertiary hospital with active symptomatic vernal keratoconjunctivitis. All the patients had proliferative lesions and corneal involvement despite conventional medications, including topical steroids. All other medications, systemic and topical: steroids, antihistamines and cyclosporine, were unsuccessful. Patients were treated with topical 0.03% Tacrolimus ointment twice daily for 8 weeks and then once a day for the next two month followed by thrice a week for two months. The changes in symptoms and signs after treatment were evaluated, also the development of possible complications was assessed.ResultsThe results showed a significant reduction in signs and symptoms after 4 weeks of the treatment. Clinical resolution of giant papillae and corneal lesions were seen within eight weeks and no additional drug was required during that period, except tear substitutes. Treatment was continued for period of two months and then slowly reduced.ConclusionThe use of 0.03% Tacrolimus ointment is safe and effective in children refractory to conventional treatment of vernal keratoconjunctivitis even in high temperature climate as Middle East. Due to the effectiveness of the treatment, the dosage used may be proposed for conventional use.     

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.     

全麻复合硬膜外阻滞对换瓣手术病人术后血浆皮质醇、血糖及术后恢复的影响

目的观察全麻复合硬膜外阻滞对心脏瓣膜置换手术病人血浆皮质醇(Cor)、血糖(Glu)及术后恢复的影响。方法将20例换瓣手术病人随机分为全麻复合硬膜外阻滞(GEA)和单纯全麻(GA)两组。于术前、术后4 h、术后第1、3、7天取血浆测Cor、Glu浓度,并记录术后清醒时间和拔管时间。结果与术前比较,GA组病人术后4 h,术后第1天血浆Cor水平均显著升高(P<0.05),GEA组血浆Cor水平仅在术后4 h显著增高(P<0.05),但其术后4 h,术后第1天的血浆Cor水平明显低于GA组(P<0.05)。术后第1天,GEA组血浆Cor水平即恢复致术前水平,GA组至术后第3天才恢复致术前水平。两组病人Glu从术后4 h至第7天均高于麻醉前水平,GEA组升高的幅度小于GA组,在术后各时点两组之间差异有显著意义(P<0.05)。GEA组病人术后清醒时间、术后拔管时间早于GA组(P<0.05),术后VAS显著低于GA组(P<0.05)。结论全麻复合硬膜外阻滞可减轻心脏换瓣手术病人应激反应和术后疼痛,有利于病人术后早清醒与早拔管。     

不同麻醉方法对乳腺癌患者血液流变学的影响

目的比较两种麻醉方法对乳腺癌患者血液流变学的影响。方法32例ASAⅠ~Ⅱ级行择期乳腺癌根治术患者随机分为两组:Ⅰ组为全麻组;Ⅱ组为硬膜外加全麻组,诱导前硬膜外给2%利多卡因5 ml,继之行全麻诱导。全麻用药两组相同,Ⅱ组术中每50分钟硬膜外给2%利多卡因6~8 ml。术后24 h内用0.5%布比卡因镇痛,Ⅰ组术后肌注哌替啶镇痛。分别于麻醉前、麻醉后30、90 min各取桡动脉血10 ml,测血液流变学指标。结果两组麻醉后309、0 min全血高切及低切粘度、红细胞压积及红细胞聚集指数下降(P<0.05),但Ⅱ组这几项指标下降明显且持续时间长,且有血浆粘度及纤维蛋白原浓度的下降(P<0.05)。结论全麻加用硬膜外阻滞对血液流变学的影响更有利于预防术后上肢静脉血栓的形成。
