Pearls:
1. Subcutaneous unfractionated heparin is used for prevention of DVT in
immobile patients or in hospitalized patients unable to ambulate. However,
after orthopedic surgery, especially after joint procedures, its efficacy is
very poor, given the increased venous stasis ,you should use warfarin.
2. Both chronic laxative use and chronic diuretic use can produce
hypokalemia. Severe hypokalemia, with plasma potassium <3 mEq/L, can
markedly affect skeletal, smooth, and cardiac muscles. Skeleta

onset of PE. if pt has nephrotic syndrome, these pts are very high risk for
PE/thrombosis.
watch his o2 sats, check EKG, if hypoxia cannot be corrected with high flow

长见识了,说到抗凝又有个疑问,是不是西方人的凝血功能特强啊?我看ICU每个病人都是用heparin来DVT prophylaxis. 在国内很少见用的,即使是大手术的病人,就看到有做心脏手术有用的,也没见谁得DVT或PE了。是不是我太孤陋寡闻了?谁来解一下惑。

不佩服风mm不行,又学了不少。
没有人想到PE吗?半夜里把attending叫起来后,她第一个反应是病人又来了一次PE。
病人在做CT前就被上了heparin drip,转到了ICU。PT INR回来后是1.2. SaO2很好,没
有chest pain, SOB.
至于fluid,a-fib八成是和这个有关,病人的确如风mm分析的以前的echo有右心扩大,
LV的EF是正常的,我和senior谈了他还是认为要bolus病人。肺没有crackle,CXR没有
congestion. 脚也不肿,不太像是fluid overload. 现在病人还在run着fluid..... 我
不知道well compensated的右心衰是不是需要fluid restriction.
BMP回来后钾只有2.1,低钾会导致afib吗,不太确定。
BUN 55,Creatinine 1.2, 看上去像dehydration. 这个肾功能你们会让病人去做
contrast CT吗?

PE is always high on the list of any patients with active malignancy,
heparin is a no brainer at those situations, esp if pt has DVT/PE in the
past, and her INR is subtherapeutic.
also very important, she should be on lovenox lifelong as long as her cancer
is not cured, instead of coumadin.
but I am not that sure her rapid onset of Afib in this case is caused by
another epside of PE because she did not present with related symptoms(breas
swelling is her chief complain) and her afib only happened

最后更新一下最新进展,attending还是决定hydrate病人后送去CT,CT结果是。。。。
。。。。没有PE. 病人on heparin同时加了coumadin,明天我去问问她为什么不用
lovenox.
cardiologist给用了amiodarine drip, 病人不久就恢复了sinus rhythm. 病人血压还
是出奇的低,对fluid没有反应,一度降到70,很吓人,但病人却没什么不舒服的。他
们还是给上了dopamine.
afib的病人自然是查了TSH了,呵呵,是正常的,troponin也正常。
明天又要on call了,看看会不会收到有趣的病人再来和大伙讨论讨论。

好惨,所以大家一定要养成随时随地document的习惯,出了事,个个都把自己撇的清清
楚楚的,intern没有上级医生的指示哪敢擅自停heparin。
给PE病人tPA,挺新奇的,都没见到过。还有做angiogram,都确诊了还做啥,就算没确

Why the patient needs pulm angiogram?
It is unnecessary at all on this case. I had one PE patient who was treated
with tPA and heparin expired anyway. no one would operate on a dying patient

这件事怎么想怎么觉得郁闷:
1“How much bleeding risk will the bolus add to the heparin drip? ”我后来
去查了查文献,竟然没有查到,就想:What’s the possibility that such a
clincal trial exists?越想越觉得主治医都未必知道答案. 可当时为什么不反问主治
医一句:“What do you think?”结论是:因为我这一段时间被三年级印度MM训练的,
都不会反问了(详见第二段)。以后要改回来!
2印度MM这么当众揭人疮疤,难道那连柳下惠故事都有的印度古老文明里,就没有类似
“打人不打脸、骂人不揭短”的话么?
我曾经仔细想过,如果我是resident的话,应该怎么做?我想我应该:
(1)主治医查房时候能不提尽量不提,因为纵使患者真的出血了,你能分清是肝素持
续静点还是bolus 引起的吗?处理上又有什么区别呢?
(2)如果打算查房时候提出来讨论学习的话,我会先和 intern 达成一些共识,

来自主题: MedicalCareer版 - 给马上开始intern的xdjm的几点建议
Nice! Very very helpful~
我只做过Sub-I,没有intern的经验,不过医学都大同小异吧,也和大家分享一下。
每天给药的时间是固定的,我们这里BID是900和1500,Q12h是900和2100,TID是600,
1200,1800,Q8h是600,1400,2200。如果上午十点写一个抗生素Q12h的医嘱,护士要
到晚上9点才会给药,所以要在后面写一个first dose now,病人才会得到及时治疗。
不写的话主治医生下午一看,病人高烧半天了,什么抗生素都没上,肯定要皱眉头。
每个人都会犯错误,客气的指出别人的错误,避免医疗过失,别人会非常感谢你。我曾
经指出过一个chief忘记给术后的heparin,另一个chief医嘱写错写到别人的chart上。
还有高烧病人送了血培养实验室却返回尿培养,intern只打了个电话说实验室没收到就
放弃了,我反正也闲的没事直接到实验室去翻一张张送检单,结果发现是和另一个病人
标签贴反了。所以那些高年都对我特别好,因为他们知道我会仔细的检查每一个医嘱,
让他们很放心。
