两种麻醉维持方法对鼻内镜手术患者苏醒期转归的影响研究

目的：观察两种麻醉维持方法对鼻内镜手术患者苏醒期转归的影响。方法：将鼻内镜手术40例随机分为观察组和对照组各20例。观察组采用静脉泵注丙泊酚复合雷米芬太尼进行麻醉维持;对照组采用静脉与吸人复合麻醉。比较两组术后拔管、清醒时问、术后躁动评分、意识状态评分,以及术中、术后血压、心率和血氧饱和度变化等。结果：两组术中血压控制均较满意,出血量亦无显著差异,但观察组拔管及苏醒时间较对照组短,躁动发生率低（P〈0.05）。结论：静脉泵注丙泊酚复合雷米芬太尼用于鼻内镜术中的麻醉维持效果较好。     

聚乳酸/β-磷酸三钙多孔复合材料修复骨缺损的实验研究

[摘要] 目的 观察以聚乳酸(polylactic acid)、β-磷酸三钙（β-TCP）制备的复合材料对骨缺损的修复效果。方法 利用溶液浇铸法技术制备β-磷酸三钙/聚乳酸复合材料。将28只新西兰大白兔随机等分为两组,手术造成右股骨髁部直径8mm腔洞状骨缺损,实验组植入直径8mm复合材料,对照组作空白对照。通过影像学、组织学、图像分析技术观察骨缺损的修复效果及材料的降解情况。结果 影像学结果表明,实验组术后8周新生骨痂将缺损修复,术后16周骨痂塑形良好;对照组术后16周内均无骨痂形成,缺损未修复。组织学显示：实验组术后8周载体材料降解成较大的数块,有新骨形成;术后16 周正常骨材料之间形成贯通的髓腔;对照组为少量纤维组织连接。术后8周和16周材料降解率分别是30. 3%和52. 2%。结论 以聚乳酸、β-磷酸三钙制备的骨修复材料对骨缺损具有良好的修复作用。

阻塞性黄疸大鼠肝功能和病理形态学研究

目的:探讨胆管阻塞对大鼠肝脏功能和病理形态学的影响.方法:60只健康雄性SD大鼠随机分为6组:胆总管结扎组(BDL,n=50)和假手术组(n=10,仅游离胆总管不予结扎).BDL组据结扎持续时间又分为BDL3、BDL7、BDL14、BDL28和BDL42组(每组10只),分别于术后第3、7、14、28、42日测定血清总胆红素(TBIL)、直接胆红素(DBIL)、总胆汁酸(TBA)、谷丙转氨酶 (ALT)等肝功能指标,并观察肝脏组织病理形态.假手术组于术后7 d行上述检测.结果:与假手术组相比,BDL组大鼠肝脏功能指标明显改变,血清TBIL、DBIL、TBA值在阻塞早期(BDL3 或BDL7 组)为最高,后呈下降趋势,至实验末期(BDL42组)时仍高于对照组;ALT等酶学指标也有类似变化.BDL组大鼠的主要病理形态学改变为肝内小胆管增生和肝纤维化.结论:大鼠肝脏功能阻塞早期即发生明显的损害,机体可产生一定的代偿以改善肝功能,但持续存在的胆管阻塞最终导致肝纤维化.大鼠阻塞性黄疸期内病理形态学的改变显示其肝功能测定值并不能反映其肝脏组织的实际损害程度.     

膝骨性关节炎3D打印导板与传统胫骨高位截骨比较

[目的]评价3D打印个性化导板（patient-specific instrumentation, PSI）辅助胫骨高位截骨（high tibial osteotomy,HTO）治疗内翻型膝骨关节炎（knee osteoarthritis, KOA）的精准度和疗效。[方法]回顾性分析2019年1月—2021年2月在本院骨科行内侧开放楔形HTO治疗的35例KOA患者的临床资料。根据医患沟通结果,17例采用3D打印PSI辅助截骨,18例采用传统方法截骨。比较两组围术期情况、随访和影像资料。[结果]两组患者均顺利完成手术,3D组手术切口总长度、手术时间、术中失血量、术中透视次数、下地行走时间和术后住院时间均显著优于传统组（P<0.05）。两组早期并发症发生率的差异无统计学意义（P>0.05）。随访时间平均（14.34±2.03）个月,两组恢复完全负重活动时间差异无统计学意义（P>0.05）。随着时间推移,两组患者的VAS评分、HSS评分和膝关节伸屈ROM均显著改善（P<0.05）。影像方面,与术前相比,术后两组患者的WBLR和MPTA均显著增加（P<0.05）,...

6%羟乙基淀粉130/0.4对患者硬膜外复合全麻诱导期肺循环的影响

Objective To observe the effect of pulmonary circulation by 6% hydroxyethyl starch 130/0.4 during induction period from epidural block combined with general anesthesia. Methods Twenty-six hepatobiliary surgical patients with ASA Ⅰ-Ⅱ, aged 32 y-59 y, weighing 54 kg-73 kg, were randomized into 2 groups(n=13): hydroxyethyl starch 130/0.4 group(HS)and complex acetic acid Ringer's solution (RL). Above-mentioned solutions were infused 7 ml/kg respectively before induction. The pulmonary circulation hemodynamic parameters such as pulmonary arterial systolic pressure (PASP), pulmonary arterial diastolic pressure (PADP), mean pulmonary artery pressure(MPAP), pulmonary artery wedge pressure(PAWP), pulmonary vascular resistance(PVR) and right ventricular stroke work(RVSW) were recorded at base value(T0), 10 min after infusion(T1), 5 min after induction(T2), 5 rain after intubation(T3), 10 rain after intubation(T4)and 20 min after intubation(T5). Results PASP、PADP、MPAP、PAWP and CVP were significantly higher in group HS at T, than the values at T0 (P<0.05); PVR in group HS was obviously lower from T1 to T5 than the value at To (P<0.05 or P<0.01); RVSW was significantly higher in two groups at T1 than base value (P<0.05), but that in group HS was lower than base value (P<0.05 or P<0.01); HR obviously decreased in two groups from T2 to T5 as compared with the value at T0 (P<0.05); MAP was lower from T3 to T5 than the value at To (P<0.05 or P<0.01). PVR was obviously lower in group HS from T1 to T5 than that in group RL (P<0.05 or P<0.01); MAP obviously increased from T2 to T5 in group HS as compared with the value in group RL(P<0.05 or P<0.01). Conclusion 6% hydroxyethyl starch 130/0.4 can obviously reduce PVR during induction pe-riod from epidural block combined with general anesthesia. In all, there is no effect on pulmonary circulation by 6% hydroxyethyl starch 130/0.4.
