Cryopreservation and Related Cases

One pet cryopreservation was performed on a member's beloved cat in October. Alcor now has 33 pets in its care.

An elderly, long-time member in California suffered a pair of apparent seizures recently. He was briefly hospitalized and released after a period of overnight observation. After additional tests were completed, Alcor personnel visited this member in San Diego to assess his condition. The member continues to be cared for by a close relative and Alcor will monitor his condition through close contact.

Probate Matters: The A-1097 probate is nearing conclusion, and the executor is preparing to close the estate, now that all taxes are filed and paid. Alcor has been reimbursed for the renovations made to this patient’s property, which was bequeathed to Alcor and is on the market in California.

Patient Care

edited 11-7-06 to improve clarity

We have completed the boil-off testing for the last of our new dewars (Bigfoot #12). Though this dewar is operating at a slightly higher efficiency that the previous two, it is boiling off about 16.7 liters per day. This is nearly twice the rate of our best performer, Bigfoot #9, which consumes just over 9 liters per day. We’re discussing the return of the new dewars for repair with the manufacturer, but will likely engage in some troubleshooting before they are sequentially returned.

Patients Moved Well

Okay, maybe the patients themselves didn't move so well, but the staff and the hired crane and forklift operators moved them nicely. As mentioned also in a brief Alcor United post, "no dewars were dropped, dinged, banged or otherwise harmed" in the changing of locations. The old patient care bay is holding the two single-person cool-down dewars, a -140 degree C freezer, and a metal cabinet for wrenches and gloves and such. The new patient care bay seems a lot more full now, with all the dewars nicely in a row. (We have pictures that I hope to see posted soon.)

That old care bay will now become a consolidated filing and supplies room; the old cool-down bay will become our training area; and the freezer will be decommissioned for a while, but will eventually move into the research area for exploring higher temperature patient care alternatives.

We're extremely happy to see this step done, as it finally means we're nearing the end of the on-going construction. Moving the patients has launched a cascade of physical tasks that must now be done. Moving boxes, people, equipment; reorganizing each space; pitching and tossing where possible.... Call me silly, but I'm excited.

Tomorrow

Tomorrow is the day. We've been waiting for over a year. Tomorrow we move the patients.

The construction isn't done. As everybody already knows, we've been involved in a dispute with the construction company over the completion of this project. They basically abondoned it for a long while last year, during a time that we had more intense concerns than riding herd on languishing construction people. Unfortunately during that time, the construction company became over-extended and suffered serious critical personnel injury. Once we turned our attention back to that painfully-late project, it was too late to save it gracefully. Instead, it has been frustrating. (We're still trying to finish, but it finally won't be much longer.)

The liquid nitrogen plumbing isn't quite done. We will not have automated fills of the dewars for at least a week after the patients move. We've been pulling our entire nitrogen supply off the bulk tank since it was filled last week, but we still haven't pulled enough to replace the broken valve. Hugh, as the critical individual on this project, has decided his annual-and-only vacation at the Space Access conference is more important. We'll have to fill the dewars manually (as they need it), and Hugh will be involved with all of them until the plumbing is complete.

If there is a critical juncture in this move, it's in the fact that the plan involves using a crane to pick the dewars up and swing them around to the new space (lifting only a few inches off the ground). We know we can roll them and all the wheels are greased, so we just have to put them in reach of the crane. We'll be testing the lifting lugs, and on some dewars that are more than a decade old. The patients are safely submerged in liquid nitrogen, but we've been boiling off the uppermost layers to reduce the weight of the units. That will reduce the load on the lugs somewhat.

We've never had any of these dewars fail (or fall) with patients inside; but like the delicate move from California, this move is fraught with the potential for disaster.

We believe it will be fine and that all will be well and the new space seem used after so long unfinished. But there's that niggling doubt, that concern for defenseless things, furry or otherwise, that this could go horribly wrong.

We have tried to engineer this move for safety. Hiring professionals to do the heavy lifting, instead of rolling dewars by hand along the heavily sloped parking lot... that was for patient and staff safety. We have installed a new hoist, that will simplify the moving of patients, if a dewar should suffer a leak. We weren't able to obtain a plasma cutter in time for the move, and that may become a time-sensitive issue if one of the dewars impacts. (We have cutting tools, of course, but they would take longer in extracting the patients than the beam would.) We do have a spare dewar and enough liquid nitrogen to fill it and the means to do so quickly.

We have also tried to engineer it for speed. We don't want the bays to be split any longer than they have to, and we don't want to have to do this two days in a row. The plan is good. The plan should work.

Betty Bulk Tank's first fill

Today we took a major step in improving patient care, in that we filled our new 900-gallon bulk tank for the first time. This poor tank had been neglected for several years for several years before we spotted it on the web; it had even been exposed to the elements since before our purchase in July, 2003. When we finally rescued it in November, 2005, it had rust spots, broken valves, and a large layer of dust.

Betty cost $12k when newly-used and can hold 900 gallons. She cost more than $3k for shipping and off-loading, and $2500 for repair and restoration. When new, these tanks go for $45k, not including shipping/off-loading. We like the price, and we like the added comfort of additional nitrogen on-site.

Hugh Hixon has been working hard to restore it to operational status. He changed the vacuum valve and modified the tank to accommodate nitrogen (originally configured for oxygen); and though we’re still working on plumbing the patient care bay for the patients, we decided it was time to partially fill the tank. I won’t comment on how we watched the wrong gauge, and filled nearly-full as opposed to part-way. …
