Four methods of trepanation demonstrated on a single human skull [en]

søndag den 29. september 2013

Dr. Thomas Wilson Parry (1866-1945) owned this particular skull, which he used to perform practical research on trepanation. He performed roughly 50 trepanation experiments on the skulls of the more and less recent deceased, using in this case a shark’s tooth, a flint-pointed bow drill, a flint scraper, and obsidian to achieve the variety of holes. Parry published Trephination of the Living Human Skull in Prehistoric Times in 1923, and an amusing ballad about the practice in 1918.

Selv-trepanering [da]

En ny alternativ behandlingsform?

Heather Perry
Heather Perry
Neurophilosophy har jeg med stor undren læst interviewet med Heather Perry.

Heather Perry er en engelsk kvinde som i 2000 trepanerede sig selv for at få "more mental energy and clarity." Er der nogle moderne mennesker, som frivilligt vil lade sig trepanere og er det overhovedet muligt selv at gøre det? Åbenbart ja! Heather Perry giver selv følgende beskrivelse af forløbet:

I used a hand trepan initially, but that wasn't proving to be terribly successful. Then there was a problem with the people who owned the property we were staying in, so we decided we'd have to just leave it. I wrapped my head up in a towel and we got out of there. A couple of days later, we had another go. We abandoned the hand trepan and got an electric drill instead. I injected myself with a local anaesthetic and then slashed a big T-shaped incision in my scalp, right down to the bone. I was sat there in the bathroom feeling quite relaxed and they started with the drill. It didn't take that long at all, probably about 20 minutes. Eventually I could feel a lot of fluid moving around. Apparently, there was a bit too much fluid shifting around, because they'd gone a little bit too far and I was leaking some through the hole, but this wasn't especially dangerous as there are three layer of meninges before you get to the brain.

I min uvidenhed troede jeg, at det eneste moderne eksempel på trepanering (bortset fra når hjernekirurgerne arbejder) var Jeffery Dahmer, som efter sigende skulle have forsøgt at bore huller i sine ofres hoveder og hælde syre i, for at gøre dem til viljeløse zombier - i øvrigt uden held. Nu er jeg imidlertid blevet klogere: Selv-trepanering er en alternativ behandlingsform, som dog endnu ikke har den helt store udbredelse, og heldigvis da for det. At man selv skal foretage indgrebet ser jeg som et klart udtryk for, at man regner det for så risikabelt, at en eventuel behandler ikke skal risikere at komme i fedtefadet, hvis det skulle ende galt.

Bart Huges & Co.

Forgangsmanden på området er hollænderen Bart Huges, som i 1965 trepanerede sig selv. Han fortalte efterfølgende at selve operationen tog 45 minutter, og at det 4 timer at rense blodet af vægge og loft. Da Huges, som ellers var kendt som en af de første europæiske fortalere for brugen af LSD, efterfølgende ønsket at blive røntgenfotograferet for at få handlingen dokumenteret blev han tilbageholdt i tre uger, hvor han gennemgik diverse psykologiske test, da man mistænkte, at han led af skizofreni. De udførte test viste dog at han var mentalt rask.

Blandt Huges' disciple er folk som Joseph Mellen, Amanda Feilding og Pete Halvorson som alle i årene efter Huges' selv-trepanering fik boret hul i hovedskallen og efterfølgende er stået frem og propaganderet for sagen, bl.a. ved at stifte foreningen International Trepanation Advocacy Group og The Beckley Foundation gennem hvilken man bl.a. støtter den russiske professor Yuri Moskalenkos forskning

Filosofien bag

Formålet med at trepanere sig selv skulle være at man herved reetablere det flow af blod og cerebrospinalvæske som var før lukningen af fontanellen ved kranieknoglernes sammenvoksning. Man ønsker at revitalisere hjernens metabolisme og genskabe barndommens energi og generelt øge hjernens kapacitet. Huges har bl.a. fremlagt tankegangen i artiklen The Mechanism of Brainbloodvolume ('BBV') fra 1964, en artikel, som oftest omtales som Homo Sapiens Correctus. Den etablerede lægevidenskab advarer fornuftigt nok mod selv-trepanering og er desuden generelt afvisende overfor Huges' teori om hjerneblodsvolumen.

Det er da også ganske pudsigt at konstatere at Heather Perry i interviewet med Neurophilosophy ikke taler om trepanering som det eneste saliggørende. Tværtimod er hun lidt tvivlende hvad angår den faktiske effekt af indgrebet. Hun får det afsluttende ord i dette indlæg:

[...] it's not something that I will advocate for everyone [...] It's just something that I decided to try, to see what it was like, so there's no reason why I should be counselling them on whether or not they should have it done too. It's definitely not a miracle cure either. Having said that, I'd be a bad one to ask about the overall long-term effects, because I think my thyroid condition makes it hard to really know. Sometimes when my thyroid meds are working OK, I think I'm feeling the same buzz that I was getting post-trepanation. Maybe for me, whilst the hole was still open, it was enough to kind of boost my brain up to feel that way all the time. My head is a bit of a random one to test it on anyway, particularly as I'd done a bit too much acid to begin with.
