Hi mister Zim. Can you hear me? T so I can hear you? Hi. Uh perfect, thank you. Um Do you have any slides ready or would you like me to put the slides on for you? Uh Yeah, let me try if I can share one second, sir. Cool. If you can guide me where I can. Yes. Uh I think at the bottom uh part of the screen you'll see like one like five tabs, one of them says present now. I think that allows you to share your screen. Do you have that? Yeah, I'm just trying to find that. Sorry. Yeah, present now. Yeah. Yeah, great. Ok, I've got one person so far. We're gonna wait a few more minutes, see if we've got enough people and then we can start. Uh would you be happy for your screen record as well? Is that ok? Yeah, that's fine. Uh So I have that but uh how I get my OK presentation here. Can you see that? Uh not yet allowed to share window allowed to share screen? Yeah, if you, if you don't mind, I send you the presentation. If you can share on my Sure Yeah, thank you. Um, so do you have my email or should I, uh, I'll put my email in the chat and then uh, oh, I can see the screen now. Yeah. All right. Ok, perfect. Thank you. Cool. Should we give it a few more minutes? And then I think, um, we've got 125 people so far, let's give it a few more minutes. Yeah, it's just, uh, I can't see anyone else. Uh I can use. Um So on the right, it will say uh on the right you'll see like um a button which shows about how many who's in the, who's in the call. Um But you probably won't be able to see their screens. I think it's probably best to see your screen. Yeah, I'll keep an eye on the chat box in case there's any questions as well. Ok. Yeah. Ok. We've got uh 11 people so far. Um We, I think we should make a start so we can make sure we can finish on time as well. Um Hi, everyone. Just a bit of housekeeping rules. Um So, you know, if you're, you're welcome to keep your cameras on or you leave your cameras off, that's up to you. But if you can keep your uh microphones muted, if you have any questions, you can unmute yourself. Uh oh, at the end of the talk um or if um if you wanna answer a question, you can unmute yourself, but if you have any questions, uh if you could write them down and leave them till the end and we can try and go through all of it. So we don't disrupt the flow and make sure that we finish on time. Um If Mr Azim has opportunities to ask to the audience here for free to unmute yourself. Um but yeah, that's all I'll leave it to you, Mister Azim. Um If Mister Azim has opportunities to ask to the audience here, if you're free to unmute yourself. Um But yeah, that's all. I uh yes, I am sorry, I was trying to log in through my mobile as well in uh in case I can see it, but it's all right. OK. All right. OK, guys. Uh yeah, as uh as I'm being introduced already. So yes. Uh this is uh me uh I work as a specialty doctor in hospital and these are my credentials. So it's a, it's a, it's a vast topic. It's very difficult to cover each and everything. But uh my main aim is uh just starting from head and going to, to toe and uh just to highlight and give you uh just uh yeah, just a mind stay uh you know, so that you can work along on these things. So, uh as I said, it's not uh it's not everything, it's not uh uh it's, it's not possible to cover each and every uh topic in detail. So we start from uh head. Uh uh and uh we all see head injury quite a quite common topic in the exam about uh the head injuries. Uh uh Most of you might have seen uh bleeding, uh scalp laceration. And uh uh if, if you have the experience, you can appreciate that. It, they, they bleed uh massively. Uh So uh the scalp word in itself, uh summarizes the five layers uh of uh uh of the scalp. So it has a skin connective tissue, then ep inurois uh then loose uh connective tissue and then pericranial, the the top three layers that the skin connective tissue and epineural, they are uh quite tightly fused together and they move as a single unit on the loose connective tissue layer. And it's the connective tissue layer. The second layer that has the major are the main vessels, arteries and uh uh arteries and veins that basically when there is an injury or laceration, they bleed. Uh uh This uh this diagram actually uh highlights uh shows why the scalp laceration bleeds so massively or heavily. So you can appreciate, you know, the the the dark blue lines. So these are the ve venue channels that uh are uh you know, the end is in the, in the second layer of the scalp or the connective tissue. But they have a deeper connections to the uh uh uh uh to the uh sagittal sinuses. So there is a one at the very bottom end, uh it's called the inferior sagittal sinus that goes up and then uh communicate with the superior sagittal sinus. And you can see, I mean, these are connected all the way through the, the bony uh skull, all the way up into the, into the second layer of the connective tissue. So when there is any laceration in this area, uh these causes a massive bleeding and uh how we control this despite of the rest of the body where you have a bleeder. The main prin surgical principles are you, you, you identify the bleeder, uh, you don't blindly put sutures on, on the bleed.
