🧵for new residents and students:
Over the last year, I've done 9 threads on different suture materials. Included here are links to each of these. I'll leave this 'pinned' for now. They are:
Prolene, silk, Vicryl, PDS, Ethibond, Nylon, Monocryl, Chromic, and barbed sutures.

- One more redo🧵for the students... Here I will explain what is meant by 'French' when we are talking about Foleys and NG tubes and such. Also we will cover what the 'Gauge' of an IV means. (1/ )
- 🧵regarding several ways in which you can inadvertently damage the tissues when approximating them with sutures. These are particularly important to recognize when the tissue is thin or fragile, because this is when you may not get away with using sloppy technique. (1/ )
- 🧵regarding the Aberdeen knot: a surgical knot that may be used to secure a continuous suture. It is thought to be more secure than a square knot. We will cover how to do it, what *not* to do, and also a little-known modification that may make it even more secure. (1/ )
- 🧵regarding 'the crimp' and other technical pointers having to do with securing surgical drains with suture. We'll go over my preferred method, other methods like the Roman sandal, some errors people make, and other factoids. (1/ )
- 🧵for the new residents and students on the meaning of 'French' and 'Gauge'. We've covered this on here in the past, but a lot of new people are starting on surgical rotations, so let's look at them again. As usual, we'll cover their history and what they mean. (1/ )
- Got a letter from a poly-trauma patient from 14 years ago in whom I did a laparotomy. It describes the childrens' graduations, marriages, and new grandchildren that have taken place since the injury, along with other aspects of life. Reminds you that this work does matter. 😀
- 🧵regarding the terminology of some common suture needle types. This is a revised version of a 🧵I did several months ago (I’ve been on vacation 😎, and it’ll be a bit untiI I have new material). This is the ubiquitous SH needle we all know. But what does SH stand for? (1/ )
- Short 🧵regarding what it means when a needle driver has a gold handle. The gold handles are not just cosmetic: the needle drivers actually *are* better. To understand this, we have to know what is meant by the 'jaws' of the needle driver. (1/4)
- 🧵regarding the 'figure-of eight' suture and also the 'pursestring' suture. We'll go over what they are for, some technical pointers, and errors that can be made while doing them. (1/ )
- 🧵 demonstrating a few basic errors that can be made when working with a Bovie. Note: I won't try to cover all of the science of surgical energy devices, as Twitter threads do have their limits... (1/ )
- 🧵for students and interns on some technical pointers regarding the clamping and ligating of tissues during surgical cases. (1/ )
- Short 🧵for students and juniors about using one's forceps to 'set down' the suture threads in a running suture, so that they are evenly spaced (L picture) instead of awkward and irregular (R picture). We'll see how to do this, and what may happen at times if it isn't done. (1/)
- 🧵regarding the side hole at the end of most endotracheal tubes. This is the 'Murphy eye'. You may or may not have noticed the Murphy eye before. Here we'll briefly go over what it is for, some unintended consequences of it, and (of course) a little history. (1/ )
