I tortured a man who will die soon.
In the afternoon, when I found out what cases I was assigned
for the next day, I trudged up to the Intensive Care Unit to grudgingly filter
through two weeks’ of notes from doctors and nurses of all kinds who had relentlessly
tried, without any success, to help George get better.
His lungs were bad. He was in the final stages of emphysema,
a disease in which the connecting, elastic fibers of the lungs rot out and
dissolve, leaving behind a floppy, over-explanded lung incapable of relaxing
inward after each breath.
His journey through my hospital had started two weeks before,
when his left lung had collapsed yet again and he was wheeled into the
emergency room hoping that somebody could help him. It was very hard to breathe.
Over years the elastic connective tissue in both of his
lungs was horribly stretched, but in the top corner of his left lung, they had
stretched and stretched until a bleb had formed, an air-filled pocket whose
contents were completely excluded from the rest of the lung. The bleb no longer
participated in the taking in of oxygen and releasing of carbon dioxide that a
lung is meant to do.
One Monday morning, the bleb popped. George breathed air in,
and instead of air flowing into the alveoli, the microscopic gas-exchange units
that line the lung, the air he breathed in traveled through his mouth, past his
vocal cords into the trachea, down into the bronchi and out through the popped
bleb, and curled back around the outside of his lung, compressing the very
thing from which it arose.
This is called a pneumothorax. The latin is simple: air
chest. The mechanics are simple. The lung cannot expand. Your own breaths fight
you.
When he rolled into the Emergency Room, gaspingly short of
breath, George wanted the lung fixed. The surgeons told him that the lung could
be reexpanded with an operation, so on that afternoon they entered his chest.
They used a caustic solution to irritate the lining of the lung, hoping the
inflammation they caused would be enough to get the lining of the lung to once
again adhere to the inner lining of the chest wall. This is called pleurodesis.
The pleura is the lining of the lung, and –desis means “to stop.”
The chest x-ray after the surgery was unchanged: there it
was, the left lung, collapsed into the bottom inner corner of its half of the chest,
compressed by the product of its own breaths, too weak and floppy to expand
back into place, to move air in and out again.
After the first few sleepless nights in the Intensive Care
Unit, the fluid started to build up. His kidneys had been going downhill for
years, and they just couldn’t keep up anymore. The doctors kept giving him IV
fluid because he was wasn’t eating and his blood pressure was low, but his
kidneys couldn’t keep up and clear the water he didn’t need.
As his kidneys struggled to keep up with the fluid it began
to seep across membranes, to weep across the cell-thick tissues that separate
the body’s essential liquids into different compartments. There was too much
water, and it pushed and drizzled its way through to infiltrate the far corners
of his body, until the fluid under his skin made a soft weeping imprint where
his arm rested against the edge of his glasses as he fell asleep.
The fluid oozed out of his lungs too, into the space around
his lungs, and on the left side it fought for space with the air from the
pneumothorax, leaving little room for the lung itself.
He needed oxygen. At first, when he came into the emergency
room, he just needed four liters per minute through his nose, a little more
than he used at home, just enough to bump his oxygen level up to normal.
When I met him, fifty-five liters per minute of oxygen were
flowing through his nose, and an oxygen mask was blowing more in through his
mouth. He sat forward in bed, gasping and grunting with each breath.
He was tired. He was thin, and old, and he wasn’t making any
sense. I was tired too, so I filled out the paperwork and rushed out of the Intensive
Care Unit, eager to get home.
The next day in the late morning an ICU nurse and two
orderlies pushed George’s bed into the elevator and brought him down to the
operating room. Outside the double doors to the operating room I took the
anesthesia resident’s customary spot at the head of the bed, watching the blood
pressure, heart rate and oxygen level on the transport monitor while pushing
the weight of the hospital bed with both arms. George was grunting.
The surgeons had this idea, to bring this sick old man to
the operating room, because they wanted to make things better for him. Every
day they had to snake a bronchoscope through his mouth and into his lungs to
suction out the thick secretions that lay there, clogging up the small airways
whose patency were vital to his survival. He was too weak to cough the
secretions up anymore. So every day a thoracic surgeon slid a long thin fiberoptic
bronchoscope, a narrow tube with suction capability and a camera on the end,
through George’s mouth and deep into his lungs and found the plugs of mucus
waiting there and sucked it all out. It was horrible. Every day they did it,
and it was hard to give him any sedation because he could barely breathe to
begin with, and the whole thing made him cough so much.
George also couldn’t eat anymore. He just didn’t have the
strength, and he was working so hard to breathe, so it was no longer safe for
him to feed himself. He had a thin yellow tube snaking down to his stomach from
his right nostril, but that could clog up after days.
He was coming to the operating room for a mini-tracheostomy,
a hole in his neck that would let the surgeons suction out his lungs easily
whenever the need arose, and for a feeding tube placed directly into his
stomach through a small hole in the skin overlying it, so he could get
nutrition reliably and safely.
The alternative, of course, was dying.
But he was old and sick and tired and he was working so hard
to breathe that he couldn’t really speak much, so his wife signed the forms and
I pushed his stretcher, heavy and slow, back to the operating room that I had
painstakingly prepared for him.
The feeding tube was first. I poured liquid lidocaine into
an oxygen mask and turned up the flow. The lidocaine became aerosolized,
floating in and out of his gaping mouth with every breath. The back of his throat
became numb enough for the surgeon to insert the endoscope, about an inch
across and feet long, into his mouth, past his esophagus and into his stomach. George
fought it at first, then settled into it, the surgeon sliding the scope in and
out to visualize the folds of the stomach, the surgery fellow pinching the skin
of his abdomen with more numbing medicine, then the pressure as the fellow
eased a thin tube through the surface of his body and into his stomach.
We could have put him to sleep. We could have flushed
medications into the small IV in the third finger of his right hand that would
have removed all conciousness, blunted all pain, and relaxed his muscles. We
could have then inserted a thin plastic breathing tube into his mouth and
attached that tube to a ventilator. We could have asked the surgeons to make a
bigger hole in his neck, one that we could attach to a ventilator to breathe
for him. And at the end, when the holes had been made in his stomach and his neck,
we would have taken the breathing tube out of his mouth and connected the
ventilator to the tracheostomy and transported him back upstairs to the ICU.
Just one single dose of anesthetic would have been enough to guarantee that he stay
dependent on the ventilator for the rest of his life. Once the weak muscles of
his diaphragm felt that extra push of air coming from the breathing machine
they would have lost their own drive. So when we planned out this anesthetic,
when we found out we were taking a sick dying man to the operating room that
was fighting for every breath, my attending and I decided to keep him awake.
Their were two options: keep him completely awake for the procedure, or
guarantee he need a ventilator forever. Rarely is something in medicine so
sure.
George struggled through the feeding tube placement, but
once the wide tube of the endoscope was out of his mouth he relaxed a bit,
renewing his attention to breathing and bringing his oxygen level back almost
to normal.
Next came the tracheostomy. This time the surgeon slid a
bronchoscope in through the back of George’s numb mouth and now, instead of
sliding down the esophagus, he angled the camera upward, tucking under the
epiglottis we all watched on the video screen and diving between the vocal
cords and into the trachea, the conduit to the lungs. With every breath the
rings of cartilage lining his trachea bounced up and down, pulled by the weak
muscles of his neck and chest. The surgeon struggled to keep the camera in the
right place.
George winced as the surgery fellow numbed his neck with
lidocaine. George was struggling. I was holding his forehead back with my left hand, proferring his outstretched neck to the
surgeons.
“I can’t see you. Are you through the skin even?” The
surgical fellow was struggling to pass the tracheostomy tube through the skin
as the surgeon watched from the inside with the bronchoscope.
“I can’t advance it. I can’t even see where I am on the
video screen. Are you still in the trachea? He’s moving too much.”
The surgeon pulled the bronchoscope completely out and
changed spots with his fellow. The fellow passed the bronchoscope again and
again I held George’s oxygen mask tightly on. George was sitting bolt upright,
still struggling to breathe. Again he surgeons could see nothing, again the movement
was too much. There was blood in the airway now too: they had entered the
trachea once, twice, but never could they see well enough with the bronchoscope
to guide them all the way in safely.
I took out an LMA and smothered it with thick lidocaine ointment.
George’s oxygen level was dipping now. The LMA, or Laryngeal Mask Airway, is a
piece of soft inflatable plastic, oval in shape, that is attached to a stiff
plastic tube. You insert it in the mouth and pass it past the back of the tongue
and it seats just above the entrance to the lungs. It seals off the back of the
throat and you can push air into the lungs without having to insert a breathing
tube all the way in, farther down.
This LMA was big though, as long as George’s outstretched
hand, and I put it in his mouth with him wide awake, wide-eyed and staring at
me.
“George I’m going to put this little breathing thing in the
back of your throat because your oxygen level is getting really low. It’s going
to help me breathe for you. I know it’s uncomfortable, but you should still be
numb back there.”
The LMA twisted in the back of his throat and he struggled.
I pulled it out. Again I put it in and this time it dropped into place. The
surgeon slid the bronchoscope through it and slid in and out of the trachea,
again and again, suctioning out blood and trying in vain to see well enough to
place the tracheostomy tube that was the reason why we were all here all
together in this operating room. I held the LMA tightly in my left hand,
pulling with my wrist on George’s forehead, keeping his neck cocked back as the
surgeon tried again and again to make the perfect hole in his neck.
“We can’t get it. I’m pulling out.”
And it ended. I stopped squeezing the ventilation bag with
my right hand, I looked in George’s eyes and I pulled the LMA out. He coughed
up thick piles of blood. His oxygen level dropped and rebounded, again and
again. He was no different from when I met him the afternoon before, sitting
upright and gasping at breaths, grunting unmelodically in between. He had a
feeding tube now, and a couple of needle holes in his neck, but he was alive
and still pulling each thin breath in on his own.
We moved him back to the hospital bed that he arrived on and
brought him up the slow elevator to the ICU. A team of nurses and doctors
greeted us.
“They couldn’t get the trach. Feeding tube went in fine.
Local only, no sedation.”
Outside George’s room, I filled the ICU doctor in on the
details of the procedure, me clenching the LMA tightly in my left hand while my
wild-eyed patient struggled to breathe while the bronchoscope passed into his
trachea again and again.
_____________________________________________________
A week later I passed the ICU doctor in the hallway. He was
tall with short-cropped blonde hair and piercing green eyes.
“Remember that guy you dropped off on Monday afternoon?”
“I wish I could forget it.”
“On Tuesday he cleared. All of a sudden everything lifted
and he wasn’t confused anymore. He said he was done with everything and he
wanted to go home to die. We called psychiatry to come because nobody believed
him, but they said he was totally lucid. It took his wife a while to get used
to the idea because she had been signing all the consents up until then, but
she came around. He went home on Hospice on Thursday.”
“That’s the best outcome he could hope for. We tortured him.
If only he’d cleared a week earlier.”
If only he knew exactly what it meant when he came into the
hospital three weeks before that, when he said he wanted everything done.
