Happy New Year!!!!!

 

As you’re about to read, ours wasn’t very happy and Christmas wasn’t very merry either. The second week of December was pretty normal. Zach was on a very small amount of oxygen as the doctors thought that he had a virus which he would get over himself and the oxygen was there just to help with the oxygen saturation (sats) in his blood which was lower as a result of the virus. On the evening of the 15^th Dec Hayley and I sat down to a Chinese from one of the local takeaways and put Zach to bed. During the night Hayley noticed that Zach was making a noise when he was breathing, which is usually a sign that he’s finding it a bit more difficult. The doctors that were on that night came and had a look, and weren’t too concerned although they did take a chest x-ray. Zach was supposed to be going to Birmingham Children’s Hospital for a stem cell harvest that day and they were happy for him to still go. A quick chat with nurses soon changed that and after a phone call to one of Zach’s consultants and they all decided not to send him, just as well. Around the same time, Hayley started complaining of not feeling too well. She ended up having to go and speak to hew down the big white telephone. Sickness had been doing the rounds on the ward and it would appear that poor Hayley was its next victim. Well morning came and Zach wasn’t feeling too well, neither was Hayley, so she was sent home by the ward to tough it out and left Zach and I to stay on the ward, this being the first time Hayley had had to leave Zach. Professor Grundy came to see Zach and had a look at his x-ray. He diagnosed bi-lateral pneumonia. Zach would have some samples taken from his lungs the next day to help further diagnoses and treatment. As the day went on Zach grew more tired and uninterested. Then at about 1730ish the doctor was called again to take another look at Zach. His oxygen requirement was increasing and he was struggling to maintain his oxygen saturation level. She had a look and an oxygen mask was put on him which he didn’t like too much. Then he started to really fight and breathing was becoming more and more difficult. They took another chest x-ray and his condition had worsened dramatically. It showed a lot of fluid build-up. An Anaesthetist was called and after a little hesitation from the on call doctors, he decided that Zach needed to be intubated, which is when a tube is put down in order to maintain his airway. This would reduce the stress he was going through and stabilise him. As this was being done, the doctors called the Paediatric intensive care unit (PICU) and it was decided that Zach would be transferred. Once the ball was rolling it was a very slick operation although something no parent ever wants to see. Zach was anesthetised, intubated and moved in the space of about 40 mins. When he was anaesthetised his lungs collapsed quickly and it took a while for them to “re-recruit” or inflate the collapsed parts.

 

Once through on PICU he was put on a type of ventilator called an oscillator. This works the lungs differently from a conventional ventilator by inflating the lungs and keeping them inflated, and just panting them rather than doing breathes as you would normally. It is gentler but looks disturbing as it makes you breathe at about 300 breathes per minute. This would help to clear the fluid from the lungs and reduce the build-up of CO2 that had occurred. We were sat down with the PICU consultant and one of Zach’s consultants and they explained that he was critically ill and the next 24hrs would be difficult. Through the night Zach had made some progress and they managed to switch Zach on to a conventional ventilator. The next day things looked like they were heading in the right direction. The PICU doctors weren’t entirely happy with progress that Zach had made but he was more stable. They diagnosed him with RSV (Respiratory Syncytial Virus). This is a common virus and would make adults feel a bit rough with a cough and runny nose, but often puts healthy infants and babies in intensive care. As Zach was immune-supressed it was hitting him hard. He made very slow progress and had to be put back on the oscillator a few days later, as his CO2 was starting to build up again. The progress he had made then started slipping. The doctors then started looking into ECMO. This is a lung bypass machine, which is only available in four hospitals in the UK. It is a very specialised piece of equipment which would oxygenate Zach’s blood for him, allowing his lungs to rest and repair. It is very high risk as it involves putting one or two large cannulas into a vein in the neck. The blood is thinned to allow it to pass through the machine. The criteria that children have to meet are very specific because of the risks involved. 30% of children put on ECMO end up with brain damage as a result of bleeding in the brain. Some children don’t survive due to other complications. Well the first time the ECMO service was asked, they refused Zach. It would now appear after further discussions with the Zach’s doctors that certain staff within the ECMO service think that all children with cancer that are put onto ECMO die. So they had to find another way of getting Zach better. They tried different drugs, putting him in different positions, giving him physiotherapy to try to bring up the secretions in Zach’s lungs. Zach made some progress then stopped again. The ECMO service were contacted again, more tests were carried out and they came back….no. then Zach made some more progress and the ECMO service were asked again….no. this time they thought that he would be more at risk being put on ECMO than if he was treated conventionally. So Zach’s doctors carried on and then he started slipping backwards. One evening ended with a doctor running down the ward towards us saying that she thought Zach may be giving up as his sats had dropped significantly during a session of physio and they were struggling to get them back up, and that if we wanted to come and stand by his bed if we thought it would help. This is the sort of news that you normally get before you wake up in a pool of sweat, but this was real and happening. We stood there as Zach slowly recovered but it highlighted to everyone how ill Zach was. The ECMO service was contacted again…..no. Zach then started to slip again. We were sat down and told that they would try three more drugs on Zach. The third would be surfactant, which is a fluid used to treat ante-natal babies with under developed lungs. It has to be squirted down his ventilation tube. Given Zach’s situation and that he was on the maximum amount of ventilation the doctors said that if he deteriorated to the point where he would need resuscitation then they could not help him any longer, and they would preserve his dignity, unplug him from all his machines and drips and pass him to us, so that we could cuddle him. This is the most disturbing thing that we’ll ever probably be told. The surfactant would be the last thing they tried. By about 1 am it was time to try the surfactant. They squirted it down, it was quite disturbing as you can imagine swallowing something and it goes the wrong way. Despite his sedation poor Zach was coughing and retching, but after he settled his sats came up a bit. It takes a long time for surfactant to work. It did seem to have a bit of an effect but then he started to slip again. We were advised to call our families. This we did and by the evening of the 27^th Dec everyone was here by Zach’s bed. Come the early hours of the 28^th the nurse looking after Zach woke us up as Zach was starting to loose colour and she feared that this maybe him letting go. Everyone rushed to his bed side and we hoped and prayed and cried. His sats were dropping, along with his blood pressure and heart rate. Then they stopped dropping, and started climbing very slowly. By midday everything was looking a bit more normal but he was still critically ill. The doctors were starting to run out of ideas.

 

ECMO were contacted again….this time Glasgow said they would consider him. He needed more tests first. They scanned his heart and found a small hole. This is quite normal as Zach’s heart was working hard trying to pump blood around his lungs. After further consideration they came back…….no. He was too high risk as he had been on a ventilator too long. The ECMO option was now out. Zach would have to do this on his own. In the meantime he had been put on a gas called Nitric Oxide which occurs naturally in the lungs and helps be improving gaseous exchange. The amount he was on had gone up and up and up. The Professor in the PICU had managed to speak to a doctor in Los Angeles, who is a leading expert in RSV. He suggested putting Zach back on to a conventional ventilator, starting a 28 day course of steroids, along with sildenafil, which is found in Viagra, and would help by increasing blood flow around his lungs and give him time. The junior doctors had become fixated with Zach’s CO2 levels during his treatment and in order to treat it had been turning up the pressures on his oscillator, but because Zach’s lungs were in such a poor condition they had been chasing figures which were unachievable in his condition and the hole in his heart made this worse. So the PICU Professor, who is also a respiratory consultant, sat them all down and drew up a plan of how Zach’s treatment should go. Zach was put on a conventional ventilator and his new drugs started. The results were almost immediate.

 

Zach has now recovered to the point where they will be able to take him off his ventilator and wake him up, which is great considering he was on four drips and eight syringe drivers, all of which were running almost continuously as well as all the machines he was connected to. It has been a complete rollercoaster of emotions. It is something that you often see on TV or read about but never expect to happen to you. It makes you take a good look at everything in your life and puts a whole new perspective on it. The last three weeks have flown by despite the longs hours of waiting for tests and results. You completely lose track of the time and the days. Our next milestone is still to get to Birmingham for Zach’s stem cell harvest and examination under anaesthetic (EUA) of his eye before his chemotherapy starts again and to get him a MRI scan to see how his brain tumour has been getting on without chemo. They have drawn some of his cerebral spinal fluid (CSF) and didn’t find any cancerous cells which is good as it means it hasn’t spread during this episode.
