СКАЧАТЬ article about Mario and the tube I’d designed, and, although Oslin was much smaller, she wondered whether we could do anything to help him. When I first met the lad he was wearing a bright red shirt, had tight, curly black hair, and was pushing himself around the ward on a kiddies’ bicycle with his back to me. Susan called to him and he turned around. The sight of his face took my breath away. There was no hair on the front of his scalp and no eyelids, just white sclera and a severely burned nose and lips. His neck was webbed from contracting scars with a tracheostomy tube in the middle. And the noise coming from him was heart-rending, a kind of rattling with thick mucus secretions made up by a long, noisy in-drawing of breath then a high-pitched wheeze as he forcibly exhaled. It was worse than a horror movie and tragic beyond belief. My first thought was, ‘Poor kid, he should have died with his dad. It would have been much kinder.’

      Strangely enough he was happy, as he’d never had a bicycle before the explosion. I kneeled on the floor to talk with him. He looked straight at me but I couldn’t tell whether he could see my face as his corneas were opaque, so I took his little hand. There would be no objectivity in this discussion. I needed to help him, even if I wasn’t sure how it could be done. We could work that out.

      By this point I was chief of cardiac surgery in Oxford and I had to get back there to operate. In any case there was no Westaby tube in Cape Town, and if there had been it wouldn’t have fitted anyway since the adult size was too big. Could I persuade Hood over in Boston to make a smaller tube? Probably, but not within the time frame that we’d been presented with; if he developed pneumonia in the next couple of weeks he’d surely die.

      My return flight to Heathrow was the following day, so instead of going for lunch in the harbour I asked Susan whether she’d take me to see Oslin’s township. Cape Town was my favourite city in the world but this was an aspect I’d never seen before, the sort of place that warranted an armed escort through its thousands of acres of misery and depravity. I’d come back in a couple of weeks when I had the tube, and a surgical strategy – that’s what flying time was for. I quickly had it clear in my mind and before the plane touched down in Heathrow I’d drawn up the operation in detail.

      I was back at the Children’s Hospital in three weeks. There had already been a fund-raising drive to help Oslin and they expected to pay my expenses. But none of that mattered. I was driven to help the boy as no kid on earth deserved that. I guess thousands of Vietnamese children suffered the same with napalm, but I hadn’t met them. I did know Oslin and I cared about him. So did the doctors and nurses at Red Cross. Perhaps the whole of Cape Town cared. As the airport taxi reached the city I saw the newspaper billboards emblazoned with ‘UK Doc flies in to save dying Township boy’ stuck on lamp-post after lamp-post. No pressure then.

      At the hospital I met Oslin’s mother for the first time. She’d been at work when the gas cylinder exploded and was now clearly depressed. She said virtually nothing, but signed the consent form for an operation that even I didn’t understand.

      We operated the following morning. I’d needed to trim the adult tube by shortening both bronchial limbs, the tracheostomy T-piece and the top part that would sit below his vocal cords, but even this shortened adult tube wouldn’t fit inside the two-year-old’s scarred windpipe. My objective was to rebuild his major airways around the tube. If it worked he’d have even wider airways than before the accident.

      Clearly he wouldn’t be able to breathe or be ventilated during the reconstructive surgery, so we’d do it with him supported on the heart–lung machine. This meant we’d open his sternum as we would in a heart operation. The tricky part was to gain access to the whole length of the trachea and main bronchial tubes from an incision in the front of his chest, these structures being situated directly behind the heart and large blood vessels.

      I’d already worked it all out on a cadaver in the dissecting room in Oxford. When a sling was placed around the aorta and the adjacent vena cava they could be pulled apart to expose the back of the pericardial sac, like opening a pair of curtains and looking out onto a tree. Then a vertical incision between the two served to expose the lower trachea and both main bronchi.

      My plan was to fillet these damaged tubes then lay in the modified T-Y stent. Next we’d repair the front of the opened airways and cover the tube with a patch of Oslin’s own pericardium. It would be just like sewing an elbow patch onto a worn jacket sleeve. Simple. It should all heal up around the tube and we could maybe remove the prosthesis in time, after the tissues had healed and moulded around the silicone. That was my plan, in any case. Maybe ‘fantasy’ would have been a more realistic term, but no one else had a better solution.

      The skin incision started in Oslin’s neck just below his voice box and extended all the way down to the cartilage at the lower end of his breastbone. Since he was emaciated, unable to eat, there was no fat, so the electrocautery cut straight through to the bone, which we then sawed through. I cut out his fleshy, redundant thymus gland and dissected down onto the upper part of his inflammed trachea, all while he was ventilated through his tracheostomy tube. We needed to go on bypass before removing this and exposing the rest of his airways. The metal retractor stretched open his scarred little chest, exposing more of the fibrous pericardium. The front of this was removed for the tracheal patch and I saw that his little heart was beating away happily. Rarely do I see a normal child’s heart, as most are deformed and struggling.

      When I was ready to open the windpipe we started the bypass machine. This rendered the lungs redundant so we could remove the contaminated tracheostomy tube from the clean surgical field. Through the hole the devastation was clear to see. Poor Oslin had been breathing through a sewer. I cut down the length of it with the electrocautery and continued the incision into each main bronchus until I could see normal respiratory lining just at the limits of our access. Copious thick secretions poured out of the obstructed airways, then we scraped tissue off the walls, which caused all-too-predicable bleeding.

      But the electrocautery eventually stopped the haemorrhaging, so we inserted the shiny white T-Y tube and covered it with a patch of Oslin’s own pericardium. I adjusted the length of the rubber cylinder for the last time to get it just right, then sewed the patch into place to seal the implant. It needed to be airtight, otherwise the ventilator would push air into the tissues of the neck and chest, making him blow up like the Michelin man. With the shiny new breathing tubes attached to the ventilator we blew air into his little lungs. There was no leak. Both inflated then deflated normally. A sense of excitement permeated the room. The high-risk strategy was working.

      Oslin’s heart bounced off the bypass machine and his lungs moved freely, needing much lower pressure from the ventilator. Our anaesthetist murmured, ‘Unbelievable. I’d never have believed it possible.’ I covered the repair by closing the back wall of the pericardium, then asked that the registrar put in the drains and close.

      Through the theatre window we could see Oslin’s mother sitting in the waiting room, still expressionless and rigid with fear. I anticipated a blunt response to our news. But she was too emotionally drained to register relief, simply holding out her hand and squeezing mine. She whispered, ‘God bless you,’ then a tear zigzagged down her pockmarked cheek. I wished her a better life in the future, one way or another.

      The intensive care unit was pleased to have him back. Most of their patients were township kids having heart surgery, and some of the nurses lived in that same environment. They’d cared for Oslin and his depressed mum for weeks, watching them both deteriorate. So ‘UK Doc’ had flown in to save ‘Township boy’ and succeeded. I was proud of that. Now it was time to ride off into the sunset.

      Oslin recovered and could breathe freely through the white rubber tube in his neck. He couldn’t speak but went on to have his corneal transplants. Being able to breathe and see at the same time was as much as he could have hoped for. The little family were relocated to better social housing on the outskirts of the city – crude but clean, and safer. СКАЧАТЬ
