- I am an anesthesiologist at the VA hospital in Palo Alto.
- During the 1989 Loma Prieta quake we had two cases going on.
- Incidentally, the quake happened in the midst of the annual
- meeting of our largest society of anesthesiologists. Many of
- us were in New Orleans at that time! In any event, the room
- shook quite a bit they say, some of our equipment (on wheels) moved
- a few feet and then back. Fortunately, none of the cases were
- critical dire emergencies (more on that below), the emergency
- power worked fine, the OR suite was in a pretty new building.
- The two cases finished up without any problem.
-
- Now, very few operations involve non-stop critical activities.
- There is almost always time for the surgeon to stop whatever
- he/she is doing so as not to cut anything "by accident." That
- per se is not a great risk. A bigger risk is that you are having
- critical emergency surgery that must be completed, a really BIG
- earthquake hits, knocking out both standard AND emergency power.
- We are equipped to deal with this, although in an event that sever
- it would be pretty challenging. (For example, the heart-lung
- machine that we have has its own battery backup, and failing that
- it can be cranked by hand, though it takes a lot of muscle power).
-
- I'm not too familiar with earthquake warning devices, but I would
- guess that they would have significant numbers of false alarms.
- Furthermore, the warning isn't really going to help very much
- so it wouldn't really be worth investign in them even if they
- were reliable.
-
- We rewrote our disaster protocol after the earthquake to get people
- better prepared. Actually they all did quite well. The main
- part of our hospital was structurally damaged and had to be
- evacuated. They evacuated over 100 patients (I think) in 28
- minutes (pretty good with mostly older inpatients). One patient
- had an abnormal heart rhythm in the parking lot (the temporary
- evacuation site) and had to have it shocked electrically in the
- parking lot!
