目的比较UE可视喉镜与直接喉镜在急诊剖宫产床边患儿气管插管术中的临床效果,探讨UE可视喉镜在患儿气管插管术中的应用价值。方法选取我院2017年1月至2019年4月收治的急诊剖宫产床边有气管插管适应证的患儿40例,男17例,女23例,胎龄33~41周,BMI 11~15 kg/m~2,ASAⅢ或Ⅳ级。随机分为两组:UE可视喉镜组(U组)和Miller直接喉镜组(M组),每组20例。U组采用UE VL300SS型号可视喉镜和普通管芯辅助进行气管插管术,M组采用Miller直接喉镜,通过听诊两肺和监测P_(ET)CO_2确定气管导管的正确位置。记录声门暴露时间、完成插管时间。记录声门暴露等级、一次插管成功例数。记录牙龈出血、皮肤损伤和食管插管等并发症发生情况。结果 U组声门暴露时间明显短于M组,声门暴露Ⅰ级比例和一次插管成功率明显高于M组(P0.05)。两组完成插管时间以及牙龈出血、皮肤损伤和食管插管发生率差异无统计学意义。结论 UE可视喉镜应用于急诊剖宫产床边患儿气管插管术中,能够缩短声门暴露时间,同时提高声门暴露等级,提高一次插管成功率,减少不良反应,提高气管插管安全性。  相似文献

目的 探讨保留自主呼吸条件下七氟醚吸入诱导联合UE可视喉镜在可预料困难气道管理中的应用效果。方法 选择美国麻醉医师协会(ASA)分级Ⅰ~Ⅲ级、术前评估为困难气道的全麻手术患者50例。患者入室后自主呼吸,面罩吸入6 L·min-1氧气+8%七氟烷,间断辅助利多卡因呼吸道表面局麻,联合UE可视喉镜行气管插管。观察患者诱导前(T1)、插管前(T2)、插管后即刻(T3)3个时间点平均动脉压(MAP)、心率(HR)、脉搏氧饱和度(SpO2)的变化,记录插管时间和一次性插管成功率及诱导期间相关不良事件发生率。结果 所有患者诱导插管期间SpO2均稳定在96%以上,无一例出现呼吸抑制。一次性成功插管43例(86%),二次插管成功4例,插管时间在(136.8±35.2)s,喉痉挛、呛咳等不良反应少,2例出现牙龈少量渗血,血流动力学变化无明显差异。结论 保留自主呼吸条件下七氟醚吸入诱导联合可视喉镜气管插管应用于困难气道管理中插管成功率高、血流动力学平稳、不良反应少,是一种安全可行的麻醉诱导方案。  相似文献

Purpose

To evaluate the value of dual energy contrast enhanced (DECE) soft tissue digital mammography and ultrasound elastography (UE) in the detection of breast lesions and discrimination between benign and malignant ones.

Patients and methods

32 female patients with breast lesions were prospectively evaluated at the female imaging unit of Diagnostic and Interventional Radiology Department of the National Cancer Institute, Cairo University. Routine sono-mammography was done for each patient then these patients were submitted to DECE soft tissue digital mammography as well as UE.The DECE digital mammography scans were held via GE Senographe 2000D “GE Healthcare; Chalfont St-Giles, UK” FFDM system with some specific software and hardware adaptations.The UE exams were held on ultrasound scanner with elastography unit and 7.5?Mhz linear array electronic probe (Hitachi digital, EUB- 7500; Hitachi medical, Tokyo, Japan).

Results

This study showed that sensitivity and specificity of DECE soft tissue digital mammography and UE were 86.3%, 60% and 80.9%, 40% respectively.

Conclusion

DECE soft tissue digital mammography demonstrated significant increase in the sensitivity without a loss in specificity. DECE soft tissue digital mammography is fast-reproducible imaging tool without operator dependency. DECE soft tissue digital mammography and UE are valuable tools to evaluate equivocal lesions.  相似文献

Background:  GlideScope laryngoscopy provides a glottic view equal or superior compared to Macintosh laryngoscopy for endotracheal intubation in adult patients. Data evaluating GlideScope laryngoscopy in pediatric patients are lacking. This study compared intubation times of GlideScope laryngoscopy vs Macintosh laryngoscopy in pediatric patients.
Methods:  Sixty ASA I–III patients, aged 10 years or less, were included in this study. Prior to intubation, airway characteristics were measured, and all patients were given an airway class by a separate anesthesiologist using a Macintosh laryngoscope. Patients were then randomly assigned for endotracheal intubation using a Macintosh laryngoscope or the GlideScope, and intubation time was measured. All blades were investigated for blood traces as a surrogate of laryngeal injury.
Results:  Demographic data and airway characteristics were not statistically significant different between groups. GlideScope intubation time (14 ± 5 s) was not different from Macintosh intubation time (13 ± 5 s). Blood traces were not observed on Macintosh or GlideScope blades.
Conclusion:  The GlideScope video laryngoscope is equally suitable to facilitate orotracheal intubation in pediatric patients compared to the Macintosh laryngoscope with respect to intubation time and laryngeal trauma.  相似文献

Objective

We investigated the treatment effects of a home-based rehabilitation program compared with clinic-based rehabilitation in patients with stroke.

Design

A single-blinded, 2-sequence, 2-period, crossover-designed study.

Setting

Rehabilitation clinics and participant’s home environment.

Participants

Individuals with disabilities poststroke.

Interventions

During each intervention period, each participant received 12 training sessions, with a 4-week washout phase between the 2 periods. Participants were randomly allocated to home-based rehabilitation first or clinic-based rehabilitation first. Intervention protocols included mirror therapy and task-specific training.

Main Outcome Measures

Outcome measures were selected based on the International Classification of Functioning, Disability and Health. Outcomes of impairment level were the Fugl-Meyer Assessment, Box and Block Test, and Revised Nottingham Sensory Assessment. Outcomes of activity and participation levels included the Motor Activity Log, 10-meter walk test, sit-to-stand test, Canadian Occupational Performance Measure, and EuroQoL-5D Questionnaire.

Results

Pretest analyses showed no significant evidence of carryover effect. Home-based rehabilitation resulted in significantly greater improvements on the Motor Activity Log amount of use subscale (P=.01) and the sit-to-stand test (P=.03) than clinic-based rehabilitation. The clinic-based rehabilitation group had better benefits on the health index measured by the EuroQoL-5D Questionnaire (P=.02) than the home-based rehabilitation group. Differences between the 2 groups on the other outcomes were not statistically significant.

Conclusions

The home-based and clinic-based rehabilitation groups had comparable benefits in the outcomes of impairment level but showed differential effects in the outcomes of activity and participation levels.  相似文献
