对于因其它原因住院的危重病人,如继发急性胆囊炎(AC),由于腹痛、腹部压痛等临床表现常被原发病所掩盖,另外其它一些体征如:发热、白细胞增高、肝功能异常等也缺乏特异性,因此做出诊断往往是很困难的。作者在传统的放射性核素胆系闪烁扫描(RC)的基础上应用静脉注射吗啡进行强化,即吗啡强化的放射性核素胆系闪烁扫描(MC),减少了假阳性率,提高了AC诊断的准确性。本文报告了MC阳性的20个病例,讨论了MC阳性的可信性。资料和方法所有20个病例为截止到1992年5月31日以前35个月间,Ohio州立大学医院住院病人MC阳性病人。MC的具体方法是:首先按常规方法进行RC,静注(?)Tc放射性核素后间隔5分钟摄腹部平片共持续60分钟,如果肠道显影而胆囊未显影,则静脉注射吗啡(0.05～0.1mg/kg)后再观察150分钟。MC真阳性(TP):胆囊持续不显影且手术证实
For critically ill patients hospitalized for other reasons, such as secondary acute cholecystitis (AC), due to abdominal pain, abdominal tenderness and other clinical manifestations are often covered by the primary disease, while other signs such as: fever, leukocytosis, liver dysfunction, etc. There is also a lack of specificity, so it is often difficult to make a diagnosis. On the basis of conventional radionuclide biliary scintigraphy (RC), the authors performed morphine-fortified intravenous injection of morphine-fortified radionuclide biliary scintigraphy (MC) to reduce the false positive rate and improve the diagnostic value of AC accuracy. This article reports 20 MC-positive cases and discusses the plausibility of MC-positive. DATA AND METHODS All 20 cases were MC-positive inpatients at Ohio State University Hospital as of the 35 months prior to May 31, 1992. The specific method of MC is as follows: firstly, RC is carried out according to the conventional method, and the flat abdomen is lasted for 60 minutes after the intravenous injection of Tc radionuclide for 5 minutes. If the gut develops and the gallbladder is not developed, morphine (0.05 ~ 0.1 mg / kg) and then observed for 150 minutes. MC true positive (TP): Gallbladder continued undeveloped and surgically confirmed
