The overall diagnostic accuracies of EUS and US for small PLGs were 80.9% and 63.9% （P 〈 0.05）, respectively. EUS correctly distinguished 12 （63.2%） of 19 neoplastic PLGs but was less accurate for polyps less than 1.0 cm （4/10, 40%） than for polyps greater than 1.0 cm （8/9, 88.9%） （P = 0.02）.CONCLUSION： Although EUS was more accurate than US, its accuracy for differentiating neoplastic from non-neoplastic PLGs less than 1.0 cm was low. Thus, EUS alone is not sufficient for determining a treatment strategy for PLGs of less than 1.0 cm.展开更多
目的观察右美托咪定预防腹腔镜下胆囊手术术后恶心、呕吐（postoperation nausea and vomiting,PONV）的效果。方法选择择期行腹腔镜下胆囊手术的患者60例,随机均分为3组：右美托咪定0.05μg·kg^-1组（D1）、右美托咪定0.1μg·...目的观察右美托咪定预防腹腔镜下胆囊手术术后恶心、呕吐（postoperation nausea and vomiting,PONV）的效果。方法选择择期行腹腔镜下胆囊手术的患者60例,随机均分为3组：右美托咪定0.05μg·kg^-1组（D1）、右美托咪定0.1μg·kg^-1组（D2）和生理盐水组（NS）,每组20例。麻醉诱导：静脉给予咪达唑仑0.05mg·kg^-1,顺式阿曲库铵0.15mg·kg^-1,芬太尼2μg·kg^-1和依托咪酯0.3 mg·kg^-1,3min后进行气管插管采取机械通气。麻醉诱导插管后各组给予相应药物容积均为5mL。麻醉维持以丙泊酚4~12mg·（kg·h）^-1和瑞芬太尼0.25~2μg·（kg·min）^-1泵注,顺式阿曲库铵间断静注,围术期保持患者的各项生命体征平稳。记录术后24h时内头晕、头痛不良反应及恶心、呕吐的发生情况。结果 D1组、D2组PONV的发生率均明显低于NS组（P〈0.05）;而不同剂量药物的D1和D2组PONV的发生率比较差异无统计学意义（P〉0.05）。结论右美托咪定能有效减少腹腔镜下胆囊手术PONV的发生率,0.05μg·kg^-1与1μg·kg^-1剂量的右美托咪定的效果无明显不同。展开更多
