24 février 艾滋病病毒感染初期症状有“接触可能”才注意这些症状,否则,还是不要看的好,以免过度担心。 1.持续低热(93%) 2.疲乏(90%) 3.原因不明的喉炎(70%) 4.体重突然下降10%以上(70%) 5.头痛(60%) 6.恶心(60%) 7.肌肉和关节痛(60%) 8.夜间盗汗(50%) 9.持续腹泻(50%) 10.皮疹(40%) 有相当一部分人在感染HIV病毒后,可以在长达十年之内没有任何明显症状。但其血液、精液里还是含有病毒。期间如果发生危险性活动,将会把病毒传染给性伴。所以没有症状不一定没有受过感染。 阴冷的天气,我抱着Everwood取暖天气转冷,竟下起小雨。 两天之内所有空床全部住满,下周一手术连着7台(要不是停了一台,就是8台了)。接病人,开医嘱,问病史,写首程加大病史,准备术前谈话,记病程,我跟亮两个人累得差点趴下。还好遇上周末,虽然星期天刚好轮我们这边急诊。 昨天的一台LC,发现居然有HIV初筛弱阳性,吓了一跳。还好没有针伤,没有血液接触,手套完好。 下午回来,有些疲倦,书也不想看,网也不想上。外面下着雨,阴冷的天气,使我愈发觉得累。于是,打开KMPlayer,电脑里有新下的PB和Heroes,但我还是选择了Everwood。躺靠在床上,听着熟悉的悠扬的片首音乐,真是惬意,人也放松下来。也许,这就是Everwood的魅力所在吧。 回来了么?打个电话回家,“喂?你好!”接的是姐,然后是爸,就在身边,很融洽。 回来了么?幸福。 临床药理学 笔记之四表观分布容积(apparent volume of distribution,Vd) 代表给药剂量或体内药物总量与血浆药物浓度相互间的一个比例常数 Vd=Dt/Ct (单位: L/kg) Vd的生理意义及应用

Balthazar et al developed a grading system in which patients with acute pancreatitis are classified into 1 of the following 5 grades:
Patients with grades A and B pancreatitis have been shown to have mild uncomplicated clinical courses, while most complications of acute pancreatitis occur in patients with grades D and E. Balthazar et al further constructed a CT severity index (CTSI) for acute pancreatitis that combines the grade of pancreatitis with the extent of pancreatic necrosis. The CTSI assigns points to patients according to their grade of acute pancreatitis as well as the degree of pancreatic necrosis. More points are given for a higher grade of pancreatitis and for more extensive necrosis. Patients with a CTSI of 0-3 had a mortality of 3% and a complication rate of 8%. Patients with a CTSI of 4-6 had a mortality rate of 6% and a complication rate of 35%. Patients with a CTSI of 7-10 had a 17% mortality rate and a 92% complication rate. Grade of acute pancreatis and the points assigned per grade are as follows:
Grade of necrosis and the points assigned per grade are as follows:
Degree of Confidence: In a prospective study of 202 patients, Clavien et al reported a 92% sensitivity and 100% specificity in diagnosing acute pancreatitis via CECT. Balthazar et al report an overall accuracy of 80-90% in the detection of pancreatic necrosis. Small areas of necrosis involving less than 30% of the pancreas can be missed. Nevertheless, the extent of pancreatic necrosis has been found to correlate well with operative findings and clinical severity. In a study by Block et al, the positive predictive value of CECT for pancreatic necrosis was found to be 92%. False Positives/Negatives: The pancreas may appear normal in approximately 25% of patients with mild pancreatitis. In the acute phase of pancreatitis a small number of patients will have a false-positive diagnosis for necrosis due to massive interstitial edema and vasoconstriction of the vascular arcades. Repeat CT within a few days may show normal pancreatic enhancement. 6 février 充实下午连续两台手术,一直到五点,还好主任厉害,算很快了,有些累,腰酸。 下班后,迅速去做CNN的节目,完成后,颈部好酸,摸一摸脸,发现双手还满是乳胶手套的气味。 这,就是充实么?至少,学到很多,忙中有乐。至少,不再拖沓,不再懒惰。 |
