Subject: RE: [CCM-L] A scary parable of H1N1

Notes:
NZ: New Zealand
FLAARDS : Flu-A-Associated-ARDS (acronyme moqueur du Dr Steve Webb)

1) H1N1 is not SARS or Ebola ...

2) Everyone working in NZ ICUs who was not either sick themselves with H1N1
(very very few) or looking after sick children at home (very few)  came to
work.

3) No-one in our unit caught it from a patient. I know of a couple of
healthcare workers in other ICUs who got it (and were not hospitalised) but
in whom it was thought that they caught it via "home" (via their children,
from school etc).

4) It just reached "stage 2" of the 4-stage "disaster" scenario I  talked
about in Singapore a couple of years ago (attached FYI). (i.e. it was "A
very large problem with preserved function of most of the hospital
infrastructure").

5) (ici, "private joke" sans intérêt)

6) Yes, Lou, perhaps one in eight to one in ten of those ventilated  will
"need" ECMO. Let me just say a couple of things (disclaimer I am NOT an ECMO
practitioner) -- a) ECMO centres vary as to their criteria -- NZ has been
(what do you expect) quite "harsh" and taken on patient who had P/F ratios
of <50, and are failing despite "other manoeuvres"  (high PEEP, reverse
ratio, inhaled NO, prone position, aggressive
diuresis/ultrafiltration). b) Severe FLAAARDS is associated with  obesity --
some of it massive -- e.g. we had a patient who was 38w  pregnant and
weighed 175 kg, who survived without ECMO but took a  month on IPPV -- and
ECMO is technically VERY difficult in very obese  people. Some patients who
otherwise met ECMO criteria were not treated with ECMO because of massive
obesity.

7) As I've said many times -- shunt reduction manoeuvres (high mean airway
pressures, inhaled NO) were often surprisingly effective. We used NO and do
not use prostacyclin. I know some Aussies did use  inhaled prostacyclin and
were less than impressed with it. Be slow to  wean the PEEP below 15 or so
(if you once needed 20 to get adequate  oxygenation). Beware barotrauma,
even WITH strich conformance to  ARDSnet parameters.

8) We had one patient with pancreatitis Lou, no other specific  surgical
issues came to light with this that I know of in NZ.

9) Here is a rapid response publication which tells a great deal about  the
national health impact --
http://www.eurosurveillance.org/ViewArticle.aspx?ArticleId=19319

Those people who would like to know "population estimates" should read it
carefully. Of course, it may have different epidemic  characteristics in
different countries, and it may also have marked regionally variable
impacts.

PDF from journal not yet available -- so I made one from printer-version
plus figures (attached) if you would like that (easier to print and read).
Home-made it is 5  MB -- hence yousendit.
