welcome to another MedCram coronavirus update so I wanted to go over the recent

numbers and total deaths is 910 that means that it surpassed SARS total

recovered is a good three and a half times now the total number of deaths

about a week ago they were substantially below the total number of deaths so

we're seeing an improvement here in the total number of recovered now these

numbers are provided to us from the w-h-o the CDC and a number of other

agencies recently here there's been some news that China seems as though but that

w-h-o is now being allowed to go in and that team is being headed up by dr.

Bruce I'll would according to the New York Times article if we look here the

others that they have listed here is actually on the cruise ship

just south of Tokyo you can see that they're wanted to talk about a recent

article that was just published in JAMA the Journal of the American Medical

Association on February 7th and we will put a link in the description below that

links to the article I think is an excellent article and basically it's a

description of 138 patients that were admitted to a university hospital in

Wuhan and describes exactly what happened to them this is an article that

looked at patients that were admitted from the first of January until the 28th

of January and at this hospital there was a total of 138 patients how do they

diagnose these all of these were positive for coronavirus but they did

not look at serum viral titers or serum viral load they looked at sputum so

that's one of the weaknesses of the study the other thing I want to mention

here is these are 138 patients that were sick enough to come to the hospital

that's really important to understand because this is going to give you a

limited look at what happens to patients who are sick enough to come to the

hospital and seek medical attention so what they noticed in the article is that

first of all the patient has symptoms then they typically developed shortness

of breath then they became admitted to the hospital

then after they admitted to the hospital one of two things happened either they

were admitted to the intensive care unit or they were admitted to the regular

floor and then we'll talk about where it goes from there now in terms of timing

that's important to get to as well from the time of symptoms to the time of

shortness of breath was about five days according to their survey and then from

shortness of breath to admission here at the 138th was two days on average and

then from admission to intensive care if they were gonna go to the intensive care

was one day so let's talk about what those symptoms were so first of all the

average age of patients admitted into the study was 56 years old and unlike

previous reports that showed a real high predilection to men only 54% of these

patients were male when I say only it looked more like a 50/50 kind of mix as

opposed to 60 or 70 that had been shown before so what were the symptoms fever

was seen in ninety eight point six percent of the patients kind of an

ironic figure given that 98.6 degrees Fahrenheit is the average temperature

for a human being a fever is defined by the way as a temperature of greater than

100 point four Fahrenheit or 38.0 degrees centigrade fatigue was seen in

about 70% of patients cough was seen in 59 percent of patients low lymphocytes

what we call lymphopenia a common sign that you can see in viral infections

that was seen in as high as 70 percent of patients a prothrombin time PT that's

of a measure of the Bloods ability to coagulate when you have a high PT that

means that your blood is a little bit more thin and that was seen in about 58

percent of patients an elevated lactate dehydrogenase which is another lab value

typically seen in viral infections that was seen in about 40 percent now when

they looked at CT scans a hundred percent of those patients have what they

call ground-glass opacities that's inflammation in the lungs and that's

consistent with what we see in a viral pneumonia of any type so

in other words what we're seeing here is not very specific for coronavirus but

could in fact be seen in a flu could be seen in other types of viruses that

could do this one of the things though that they saw is that there was a

substantial amount that had just nausea and vomiting and that was kind of

unusual it wasn't as high as eighty to ninety percent but it was there in terms

of treatment for these patients almost all of them receive a settlement which

is the flu medication also antibiotics were used on the majority and in about

forty five percent of patients steroids were used they weren't really able to

tell whether or not any of this stuff had a benefit to the patient

of course this study was not designed to look at that so let's look at the 138th

patients that came in the first thing I'm gonna mention to you and we're gonna

talk about this at the end I think this is probably the biggest thrust and the

biggest surprise out of this paper was that 41 percent of these patients or a

total of 57 patients were patients that did not come to the hospital with the

corona virus but in fact picked it up there we call that a nosocomial

infection so yes there were patients at the hospital that were there for a

completely different reason and they developed corona virus at the hospital

and there were health care workers that went to work without corona virus and

picked it up taking care of patients at the hospital what percent of the

patients in the hospital that were treated for corona virus had that a

substantial amount 41 percent we'll talk about that at the end of this

presentation so of these 138 patients regardless of whether or not they came

to the hospital with it or not or developed it there what happened to them

so of 138 and on average after about one day there was a decision to have them

move to the intensive care unit about 36 patients or 26 percent of the 138 went

to the intensive care unit and 74 percent were stable enough to be

admitted to the regular floor so let's focus our time a little bit on what

happened to the patients in the intensive care unit so why did they have

to go to the intensive care unit well there's many reasons why somebody could

go to the intensive care unit for instance they could go into a RDS they

could have a serious arrhythmias or they could go into shock sometimes

you can have more than one of these things so don't expect all of these

things to add up but if you look at of the hundred and thirty-eight how many of

them had a RDS 16 percent of patients admitted to the hospital had to go to

the intensive care units for a RDS reasons of the people who are admitted

twelve percent of the hundred and thirty eight had arrhythmias and eight percent

of people admitted to the hospital had to go to the intensive care unit because

of shock now if you want more information on a RDS please look at our

a RDS video how coronavirus kills and that describes what a RDS is in detail

and what are the treatments that the intensive care unit can use to treat

these kind of things now of those that went to the intensive care unit

what kind of oxygen supplementation did they need there's three basic types of

oxygen supplementation that you'll see in the intensive care unit one is known

as high flow oxygen the other is non-invasive positive pressure

ventilation this is kind of like CPAP but it's actually called BiPAP because

the ventilator helps you when you take a breath in so it gives you a higher

pressure when you're breathing in and it'll lower pressure when you're
