Earlier this year the dramatic story of a makeshift operation aboard an aircraft flying from Hong Kong to London hit Britain's newspapers. Here the surgeon who performed the in flight operation gives an account of what happened, and he and the other doctors who treated the patient assess the problems of managing medical emergencies in the air.
A personal account
I was on board a Boeing 747 bound from Hong Kong to London and was seating myself before departure when a call was made by the stewardess: “If there is a doctor on board would they please make themselves known to the cabin staff.” I offered assistance. A 39 year old woman in the back row of economy class had become concerned about the swelling developing in her forearm which another doctor, Dr Tom Wong, was examining as I joined him. She told us that she had fallen off a motorcycle on the way to the airport. She had been shaken by the accident and had missed her original flight before catching this one. The problem appeared to be bruising and a probable minimally displaced fracture of the right forearm. She did not complain of any other injuries, and though I had attended an advanced trauma and life support course in 1990, I did not carry out a full primary survey—there seemed to be no need, and it might have been misunderstood by the patient.
I decided that the forearm injury could be managed satisfactorily on board. I recommended that in the first instance the arm should be raised on a pillow and that more formal splinting could wait until after take off, to avoid any delay to the flight.
After take off, when the seat belt signs had been switched off, Dr Wong and I splinted the arm. Samsplint—a flexible aluminium and rubber based splinting material, a bandage, and a sling were all available in the plane's M5 medical emergency kit. A Hong Kong newspaper was used as additional padding. The splint was effective, the arm was elevated, and the passenger felt comfortable. I then completed a medical report with the air stewardess. All seemed well and we returned to our seats to enjoy our first meal on board.
The first signs of real trouble
About 45 minutes later (more than an hour into the flight) I was told that the passenger had developed left sided chest pain, which she had noticed when she had bent down to remove her shoes. Examination confirmed tenderness of the lower left ribs with probable fractures of between two and four ribs.
An injectable painkiller was indicated for the rib fracture pain and this was sought from the emergency kit. The kit was well supplied with drugs and also included a guide on their recommended dosages. An injection of nalbuphine was prepared, but when I returned to the patient she was obviously ill. The injection was not given, and I re-examined her. She was in respiratory distress with mild tachypnoea. Chest percussion and auscultation could not be carried out effectively because of the engine noise but her trachea was significantly deviated to the right. I realised there was a serious problem and asked Dr Wong for a second opinion. He agreed with the findings and an oxygen mask was immediately applied.
I then visited the flight deck and explained to the captain that the patient had a tension pneumothorax and asked if medical advice could be obtained from the ground, particularly advice on the available surgical equipment. It was not possible to receive immediate advice and I decided to proceed with surgery.
In flight surgery
The aircraft's medical kit had a scalpel, sharp pointed scissors, and a 14 gauge urinary catheter. Xylocard (100 mg of lignocaine in 10 ml) was available for use as a local anaesthetic, but in the heat of the moment, neither I nor Dr Wong were able to calculate the percentage of lignocaine in it.
There the routine equipment ended; we prepared heated hand towels for sterile drapes, a modified coathanger as a trocar for the urinary catheter, a bottle of Evian water with two holes created in its cap for use as an underwater seal drain, and a length of oxygen tubing to attach the catheter to the drain. In addition Sellotape was used to anchor the catheter to the oxygen tubing and five star brandy as a disinfectant for the introducer.
I advised the patient that she had a serious condition and that an operation was required, but she was too ill to give written consent. With the patient seated in her aircraft seat, the operation—the insertion of a chest drain under local anaesthetic—was performed. I planned to insert the chest drain into the left second intercostal space in the mid-clavicular line because this was the most accessible area and would control a tension pneumothorax. As soon as the drain was connected, air was released from the pleural cavity and within five minutes the patient had almost fully recovered. The patient was left sitting in her passenger seat and settled down to enjoy her meal and the inflight entertainment.
I then had to prepare a full medical report for the second time, a task made difficult by the changing time zones. The air stewardess thought that we should document all the times in British Summer Time and this proved to be the best decision.
The patient was now comfortable, felt well and we retired to our seats to recover. Eight hours later I was again summoned by the stewardess to see the patient, who had developed more chest pain and dyspnoea.
I found her sitting on the toilet with the underwater seal drain on a high shelf. All the water and air had syphoned out of the bottle into the chest. The crisis resolved when I placed the underwater seal drain on the floor—draining the water back from the chest to the bottle. The air bubbled out of her chest when she coughed. After a few minutes she was almost back to normal, but exhaustion precluded the completion of a third full medical report.
Back on land
On arrival at Heathrow she was transferred from the aircraft by British Airways ambulance to Ashford Hospital. She was still mildly short of breath and complaining of discomfort over the left chest wall. Examination showed clinical evidence of a fracture of the left sixth rib in the mid-axillary line. A full blood count and arterial blood gases were normal. A chest radiograph revealed a 30% residual left sided pneumothorax; and our temporary drainage catheter had been inserted in the third intercostal space and was still in place.
She was given parenteral analgesia, intravenous antibiotics, and tetanus prophylaxis. The Foley catheter was removed and a 28 Fr chest drain was placed under local anaesthetic. A repeat radiograph showed complete lung expansion, and subsequent recovery in hospital was uneventful.
