About Indeterminate Causality

Indeterminate Causality is a collection of some of my comics, doodles, and sketches. It's a commentary on life, situations we all find ourselves in, the world of medicine, being a guy, and interpersonal interactions, with a slant towards making scenarios as amusing as possible. Updated Monday-Wednesday-Friday (I try, sometimes its difficult with school/exams and such).

New Comics

Hey all,

I know it's been a while since I've updated here. I've been on my surgery rotation and haven't had much time to draw. Comics should be back shortly! (hopefully!)

Beta Blockers

212 Beta Blockers

The screening process for getting into medical school is getting worse and worse. I blame autocorrect and spell-check.

211 Imitation

And don't be afraid to wear that surgical cap and the surgical booties around the hospital. Or at home. Or out at night.

Don't get all high and mighty that you're a med student, you're no different than anyone else. If you want to be a good doctor don't you ever forget that.

This can also be applied to Anal Fissures; be glad I didn't decide to draw that.

What? You don't think that when we're on our surgery rotation that you won't get enough practice with those exams?

What? Don't act all surprised at that. With that little awkward dirty comment you know you'll remember it forever now.

Man, you have too much time on your hands to think of this stuff. Shouldn't you be studying?

201 Stirrups

I'm not sure why, but there are a lot of exam tables that have the stirrups pointing towards the door. This was obviously a mean joke perpetrated by whoever designed the room.

Make sure you look for that sort of thing, it isn't something you want to miss.

199 Recapitulation

Which is much like a real breast augmentation, in that it will hopefully further your careers. However, if you lack any significant talent, it won't really help. Good luck!

That's where you go to get TREATMENT!

197 Murmurs

This holds true for most residents, too. And orthopods. Actually, if an ortho guy hears a murmur it is most likely at least a 5/6 because those guys don't even carry stethoscopes.

196 OB/GYN

I mean, you might as well be up all night, every night like a vampire. I'm not suggesting you become a soulless blood-sucker, though. That would just be wrong.

195 Males

You see, with inadequate air flow, the brain goes hypoxic and to keep that from happening, the blow job was invented. I'm kidding of course. I'm going to be in trouble for saying this.

Well, it could also have been a she that did those things. Stupidity isn't sexist, you know.

Replace It

193 Replace It

No, seriously, use colon. Why? Normal colonic mucosa is columnar, and when constantly stimulated by stomach acid, will undergo metaplasia. And what does it turn into? Squamous epithelium, which is exactly what we want there.

Also, I was considering getting a Masters in Public Health, and maybe a Ph.D in nanotech too. You can never have enough education!

You know, some people are pathological empathetics; they are abnormally incapable of showing empathy.

Note: Names have been changed to protect the annoying. If one of the above names is yours and you are a gunner that is purely coincidental. However, if you know me, and are a gunner, and don't see your name...well then you know what it was changed from.

185 Pirates

ARBs - Angiotensin Receptor Blockers, which are similar to Angiotensin Converting Enzyme Inhibitors or ACE Inhibitors, but without the bradykinin-induced dry cough. Pirates like ARBs because they don't have time to be coughing whilst pillaging.

Comics Are [almost] Back!

Just a heads up, new comics will start being posted again next week! I take my boards shortly and will then have some time to do some drawing. Not sure if any of you missed these, but I sure did. Monday the 25th should have a new comic!

In the mean time, if you all could send some good karma my way I'd really appreciate it.



PS. If you haven't seen it already, and want to be notified of new comics via Facebook, I have a Facebook page here

Wednesday, May 9, 2012


Hey all,

I've been really busy studying for boards lately, and haven't had time to do much [any] drawing. Sorry about that, but unfortunately school comes first. I will attempt to get some comics up when I can, but will probably not get many up before the middle of June, when I should get back to the normal 3x/week schedule. I'll get back here when I can!

Wish me luck on boards!

184 No Brainer

I mean, you could also view pregnancy as a couple's issue, in which case being female is irrelevant. The point is, make sure your patients realize that sex may equal babies.

If you win at Professor Bingo, you MUST ask a question. If you win a lot, you become that student that the professor knows by name. Play this game wisely.

Social Interaction

179 Social Interaction

I can't believe we have to sit through a lecture entitled "Empathy is Necessary in Medicine. If You Don't Have It, Learn To Fake It."
That must be frustrating for you to have to sit through. Please tell me more about it.

Obnoxious Patients

176 Obnoxious Patients

Obviously you cannot do that these days, but back when I was a resident, that's sometimes what happened.  Barbaric practices, I say. But then again I said that you can fix behavior with Haldol. Confusing, huh?

175 Edema

Excess fluid doesn't get invited to parties. It's depressed about this, and sinks pretty low.

Anatomy of a MS-II

174 Anatomy of a MS-II

Yea, it's much like the Anatomy of a MS-I, but much more haggard, and worried looking. Also, MS-II is obviously more conflicted about the end of the school year as 1. The year is ending, and 2. Boards are looming.

Difficult Patients

173 Difficult Patients

This is best if you say it in iambic pentameter, but as I'm a doctor and not a poet, I'm pretty sure that the timing or syllables are off somehow. Whatever. You get the point.

Medical Jargon

169 Medical Jargon

Actually, it could also just be that it's really simple and we want to make it seem more complex. You don't know what caput medusae is? It's quite simple to understand, if you speak Latin and know Greek mythology.

166 Windows

If there were windows, you'd have to recover from your injuries in the hospital before taking your boards, leaving you less time to study, and thus making your chances of passing much lower.
