目的 比较甲苯磺酸瑞马唑仑和丙泊酚在超声胃镜检查中的有效性和安全性。方法 采用随机对照的研究方法,选择接受超声胃镜病人60例,分为观察组(29例)和对照组(31例)。观察组采用甲苯磺酸瑞马唑仑麻醉,对照组采用丙泊酚。观察麻醉过程中不同时点的血流动力学指标、改良警觉/镇静(MOAA/S)评分各时刻的变化、苏醒及离室时间、围术期不良事件。结果 观察组的血流动力学影响更小;观察组可进入足够的镇静深度,而对照组的镇静程度更深;2组起效时间相似,且迅速苏醒而离室,但在苏醒及离室时间方面观察组稍短;不良事件对照组高于观察组。结论 甲苯磺酸瑞马唑仑应用于无痛超声胃镜检查,其对血流动力学影响小,能产生足够的镇静深度,能使患者迅速苏醒,且不良事件发生率低,总体有效性和安全性优于丙泊酚。

Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.

目的 研究添加与不加甲苯对24 h尿微量总蛋白(MPr)和尿微量白蛋白(UMA)定量测定的影响。方法 收集各个浓度段门诊及住院病人的新鲜随机尿共82份,检测即刻与在低、中、高温度条件下,加和不加甲苯保存24 h后尿液MPr和UMA的浓度,通过配对t检验方法检验差异有无统计学意义。结果 即刻尿MPr的值与低中温条件下、有无甲苯的24 h尿MPr的检测值比较,差异均无统计学意义(P＞0.05),但与在高温条件有无甲苯检测值比较,差异均有统计学意义(P＜0.05);即刻尿UMA的值与低中温条件下、有无甲苯的24 h尿UMA检测值比较,差异均无统计学意义(P＞0.05),与高温条件下有无甲苯检测值相比,差异均有统计学意义(P＜0.05);同一温度保存24 h,得到尿MPr、尿UMA的检测值,有无甲苯的检测结果比较,差异均无统计学意义(P＞0.05)。结论 实验证明甲苯在24h尿MPr与尿UMA的定量检测中无使用的必要性。

Objective To investigate the effect of toluene in the quantitative detection of 24 hour(24 h) urine micro protein(MPr) and urine micro albumin(UMA). Methods Eighty-two random urine of the patients with different concentrations were collected.The group without toluene and the other group with toluene were stored at the low, medium and high tempreture for 24 h respectively. Then MPr and UMA were measured in 0 h and 24 h. Paired t-test was used to test whether the difference was statisticallysignificant. Results When stored at the low and medium temperature,the results of immediate detection of MPr and UMA were compared with those of the addition of toluene or without for 24 h. The difference was not statistically significant (P>0.05). However, there was significant difference in MPr and UMA value of urine at high temperature under the same comparison(P<0.05). Stored at the same temperature for 24 hours, the results of MPr and UMA were compared between the adding groups and the non-adding groups. The results showed that there was no significant difference between them. Conclusion The specimens for the quantitative detection of the 24 h MPr and UMA are not need to be added with toluene, and toluene in the urine is not preservatively effective.

目的 了解和改善南沙区某制鞋厂甲苯的职业危害情况。方法 采用劳动卫生学调查方法。 结果 车间空气中甲苯浓度督导前为26.00~315.00 mg/m³,督导后浓度降至4.60~46.40 mg/m³;作业工人自觉症状在督导后有不同程度的改善,与督导前的情况相比,两者差异有统计学意义(P<0.01);暴露组白细胞减少情况与对照组间的差异有统计学意义(采用Fisher确切概率法,P<0.01);督导后血红蛋白含量下降得到明显改善,并与对照组基本接近。结论 加强职业卫生监督、定期进行职业危害因素监测和工人健康监护,对于甲苯作业的职业卫生防护具有重要意义。
