Into the blue
I am in a smallish, whitish room in a hospital in Brisbane. It is night. On the wall opposite my bed I can dimly make out a crucifix with its limp passenger. Beneath it float wide blank windows through which I watch the synapses of city light: a web of tiny illuminations and extinctions that seem, when I loosen my gaze, almost to form patterns; as if they are about to make sense. I am surprised at how calm I feel.
In the weeks leading up to this moment I have set my affairs in order. Made a will, written letters for the children, waxed my legs. Said my farewells at the airport and boarded the flight from Melbourne with my mother. July 2010.
Some months before this, after decades of resistance, I gave in at last to the inevitability of major surgery. My capitulation was sudden and took place in a different wing of this same hospital, where I had come to consult a respected spinal surgeon. The surgeon had a quiet, almost diffident, manner and a moustache that put me in mind of a doleful Groucho. I am not sure what made my mind up, the moustache or the way his finger traced my wayward spine quite gently on the X-ray before him. But just as he began to tell me that I would not be a candidate for the type of noninvasive surgery we had been talking about, I realized with a small thud of certainty that, not only was I going to have this surgeryinvasive though it might beI was going to come back to Brisbane and he was going to do it.
In the aftermath of my decision, I was buoyed in a backwash of something like relief; a giving up of hope and its attendant efforts, a yielding to forces beyond my will. But when I lay awake at night, disquiet rose around me. It was not just the surgery that was worrying methe cutting and drilling, the inevitable riskit was that in some blank corner of myself I felt that I would not wake up afterward. I knew logically, and during the day could convince myself, that for an otherwise healthy forty-eight-year-old, the likelihood of calamity was low. But at night, there in my bed in Melbourne, the conviction multiplied inside me that even if everything went according to plan, the me who woke after surgery would not be the same in some essential way as the me who had been wheeled into the operating theater beforehand. I developed a dread of the moment when the anesthetic drugs would take effect and I would cease to be. I pictured myself in a stark, poorly lit room with two doors, one in, one out, neither of which I could open from within. Otherwise the room was empty. No windows, no furniture. In this darknesswhich I now realize had the same sinuous quality as the shadows beneath my childhood bedI would be trapped alone. Perhaps forever. At least until such time as someone else chose to release, not me but some other, ostensibly similar, version of me who would slip soundlessly into the life that had once been mine.
Shortly after making my decision I rang a separate Brisbane medical practice. I asked to speak to the doctor whose job it would be to render me unconscious and keep me that way during the long operation. Halting, almost apologetic, I explained to the receptionist that I had spent some years researching the process known as anesthesia, and that I was now rather nervous about what was going to happen to me. I think I know too much, I said.
Oh dear, said the receptionist. Thats not good.
This book explores perhaps the most brilliant and baffling gift of modern medicine: the disappearing act that enables doctors and dentists to carry out surgery and other procedures that would otherwise be impossibly, often fatally, painful.
Anesthesia . The term was appropriated from the Greek by New England physician and poet Oliver Wendell Holmes in 1846 to describe the effect of the drug ether following its first successful public demonstration in surgery. Anesthetize : to render insensible.
These days there are other sorts of anesthetics that can numb a tooth or a torso simply (or unsimply) by switching off the nerves in the relevant part of the body. But the most widespread and intriguing application of this curious craft is what is now known as general anesthesia. In general anesthesia it is not the nerve endings that are switched off, it is your brainor at least parts of it. These, it seems, include the connections that somehow enable the operation of our sense of self, or (loosely) consciousness, as well as the parts of the brain responsible for processing messages from the nerves telling us that we are in pain: the neurological equivalent of shooting the messenger. Which is, of course, a good thing.
More than a good thing. I would not have boarded that plane to Brisbane had it been otherwise. And I dont assume my fears were greater than those of anyone else in my predicament. But it was also true that for the previous decade I had been deeply preoccupied with a question or series of questions, often nebulous and contradictory, that amounted to this: what really happens to us when we are anesthetized?
By this I mean not what happens to the pinging, crackling apparatus of our nerves and spinal cords and brains, but what happens to us to the person who is me or the person who is youas doctors go about the messy business of slicing and delving within us? And, fused somehow to this, another odd and stubborn question: can whatever happens (or doesnt happen) while we are under anesthesia continue to affect us in our waking lives? Can it change the way we feel or think or behave in the minutes, months and even years after surgery? Finally I wondereda niggling, almost soundless irritation largely obscured by the first two questionswhy did I care?
Not so long ago, if you were unlucky enough to need surgery and strong enough to withstand it, you would be tied down and cut open, usually conscious and probably screaming. Poppy. Hemlock. Hemp. Over the centuries healers tried every imaginable way of preventing or deadening pain: pressing on arteries, pinching nerves, soaking sponges in narcotic herbs for patients to breathe through. Some practitioners favored a blow to the jaw; others rubbed stinging nettles on one part of the body to distract from another. Alcohol. Opium. Hypnosis. Prayer. Until the mid-1800s, surgery was almost always an agonizing last resort. Most of todays routine operations were impossible, and even when they werent, many patients chose death in preference. Suffering so great as I underwent cannot be expressed in words, wrote one survivor. The particular pangs are now forgotten; but the blank whirlwind of emotion, the horror of great darkness and the sense of desertion by God and man... I can never forget.
