‘Good evening. Ipswich Hospital. Which department, please?’
‘Accident department, please.’
‘Sorry, that line is engaged. Can I put you on hold?’
There followed mindless waiting-forever music, tunes that made minutes seem like hours, time more joyfully spent waiting to be castigated by the medical director.
Then the young doctor was found.
‘Thank you, Professor. I know you’ve been in theatre all day. I’m Lucy, the on-call medical SHO. I was hoping that you would accept an emergency that has been with us for some time. An aortic dissection.’ (In medicine, people are frequently referred to by their condition rather than their name.) ‘He’s a GP and had heart surgery a few years ago – an aortic valve replacement at Papworth.’
‘Then why aren’t Papworth operating on his aortic dissection?’
There followed an embarrassed silence.
‘Their surgeon on call said he had another emergency waiting and we should send the doctor somewhere else.’
I was rather nonplussed by this approach as there were several cardiac centres in London that were closer to Ipswich. Aortic dissection is a dire emergency, where the main artery supplying the whole body suffers a sudden tear through the innermost of its three layers. This exposes the middle layer, which usually splits along its entire length under the high pressure, all the way from just above the valve down to the leg arteries. Branches to the vital organs can be sheared off, interrupting their blood supply and causing stroke, dead gut, pulseless legs or failing kidneys. Worse still, the split aorta is likely to rupture at any time, causing sudden death. And the poor chap was a doctor. He deserved better. Anyone deserved better.
I asked his age and current condition. The man was sixty and had complained of sudden severe chest pain, rapidly followed by paralysis of his right side. That meant he had extensive brain injury caused by the carotid artery supplying the left cerebral hemisphere becoming detached. The longer he was left before surgery, the less likely he was to experience any recovery. The patient couldn’t speak but sweet, persistent Lucy remained optimistic, saying that he was still awake and could move his left side.
There was one piece of critical information I didn’t have, besides his name, that is. What was his blood pressure? Before committing any patient with dissection to an ambulance or helicopter journey, it was vital that the blood pressure was carefully controlled with intravenous anti-hypertensive drugs because a surge in pressure can easily rupture the damaged vessel. So many patients die during or soon after transfer for that very reason.
‘180/100. We can’t seem to get it down.’ An element of panic had now entered her voice.
What that meant was that all the senior staff had buggered off home and left her to it, and she had never seen such a case before. After a day of conflict and castigation I chose my words carefully.
‘Oh shit! You must get that down. Get him on nitroprusside.’
I pictured the paper-thin tissue expanding to bursting point while the dissection process extended further throughout the vascular tree. Even with emergency surgery, one in four of these patients died.
Lucy responded that they didn’t want to drop the blood pressure too far because he wasn’t passing much urine and the CT scan showed that the left kidney had no blood flow. Only surgery could help fix that, so the sooner we got him onto an operating table the better. Should the guts lose their blood supply, little could be done. I asked whether he had abdominal pain or tenderness. Apparently not, so that was a positive.
This terrified patient had been lying paralysed on a hard hospital trolley for hours, surrounded by his family. He knew his own diagnosis and was fully aware that urgent surgery was his only chance of survival. Worse still, he’d had heart surgery before for an abnormal aortic valve, which is often associated with a weakened aortic wall. Reoperations are much more taxing than virgin surgery, so I summarised the situation in my mind. Physician with the highest-risk acute emergency needs reoperation but has an established stroke and one kidney down. His blood pressure is uncontrolled and he is at least two hours away by road. Could they arrange a helicopter? No, they had already tried. No wonder Papworth weren’t interested!
Lucy sensed that I was wavering. Hedging my bets, I told her that I had no idea whether we had any intensive care beds available.
So Lucy played her trump card. ‘The family asked that he be sent to you personally. Apparently you were at medical school together. I think he was a friend of yours.’
What was that question I never asked? Something we don’t regard as important – the patient’s name. Surgeons are less interested in people. We want problems to fix, but I had already had enough problems for one day.
Suddenly the penny dropped. A GP in Suffolk. My own age and with previous heart surgery. He was a jovial rugby prop forward, captain of the 2nd XV at Charing Cross Hospital, my old mate Steve Norton. We met on our first day at medical school in 1966. I was a shy, unassuming backstreet kid, frightened by my own shadow, and no one from my family had ever been to university before. Steve was an ebullient extrovert, full of confidence, destined to become a much-loved GP in rural Suffolk while I underwent metamorphosis into a fearless operating machine. Same profession, worlds apart. How did that happen?
I just said, ‘Bugger the beds. Send him across as fast as you can. I appreciate you should be going off duty, Lucy, but someone must come with him to screw that pressure down. And please send the CT scan.’
With no one to delegate to at this time of the evening, I had to make all the arrangements myself. The on-call nursing team had already worked all day and were just finishing a routine lung cancer operation. They were less than delighted by the prospect of a protracted emergency reoperation, one they expected to take all night. With foot down and blue lights flashing, the ambulance ought to be with us by 11 pm. If Steve survived to see Oxford alive, I would wheel him directly to the anaesthetic room.
Now the battle had started. Was there an empty intensive care bed? If not, there would be a bloody row about accepting a patient from outside the region without asking. Who was the on-call anaesthetist? I got lucky with Dave Pigott, a dour South African who helped with my artificial hearts and revelled in a challenge. Then lucky again that Ayrin was the scrub nurse. She was a diminutive, ultra-polite Filipino girl who never complained about anything because she was proud to work for the NHS. Her invariable response to any expression of gratitude was ‘Welcome.’ I used to think that this was the only English word she knew. The perfusionists always moaned and groaned when called at night, but they were all ultra-reliable. I just asked switchboard to call in whoever was on the rota and I looked forward to the surprise.
As the sun went down, we waited. I called home and spoke to my long-suffering wife Sarah, who thought I was in Cambridge and was sad for me that I wasn’t. I explained that I was waiting to operate on Steve Norton from medical school and wouldn’t be home tonight. That concerned her. I wasn’t the duty surgeon, and she remembered the heated discussions when I was faced with the prospect of operating on my own father during his heart attack. In the end, my cardiology colleague Oliver spared me the moral issues by curing him with coronary stents.
Sarah asked tentatively whether I should ask the on-call surgeon to do it. How did I feel about operating on a good friend at such high stakes? Cardiac surgeons are rarely introspective
