I’m sorry to hear about your dad OP, I hope you get some answers and manage to get counselling soon. The NHS isn’t in the business of euthanising their patients, so please rest assured this wouldn't have been the case but do ask for a de-brief and a copy of his notes.
As a community nurse I deal with syringe drivers on a fairly regular basis, so just wanted to address some points (haven’t read all the comments, so if these have already been addressed apologies). A syringe driver, as has been mentioned, is essentially a syringe filled with medications to assist in controlling pain, secretions, agitation and nausea/sickness. Sometimes a very small dose of steroid can be added if needed for site reactions. It’s essentially a little plastic tube that goes into the subcutaneous tissue (needle is removed after it’s inserted) and delivers the medication over a 24 hour period. Usually it’s the district nurses who replenish this daily.
Some people have mentioned that it delivers doses at a certain time, or is controlled by the patient. This isn’t the case, and maybe these posters are thinking of the medication that you can press a button and it is delivered to you. With syringe drivers the doses for the required medications are added to the syringe and diluted with either water for injection or saline for injection, so the meds are essentially all mixed together. This medication is then delivered over 24 hours continuously until it’s replenished. The syringe driver is kept in a locked box which the DNS have the key for and the key pad lock is kept on. If the patient (and/or the family) find they’re experiencing more pain/agitation/sickness/secretions, then the DNs are on the other end of the phone and can come out to administer stat doses of the medication needed to control the symptoms. The doses given are guided by the prescription. If patients have stat doses then these can be incorporated into the syringe driver at the next replenishment. The aim is to get the patient to a level where their symptoms are controlled, they’re comfortable and they’re not needing stat doses.
I've seen people mentioning that people pass quicker. This is really individual. Yes, once symptoms are controlled the patient can be more relaxed, so maybe in that way it can allow for a patient to pass quicker but this isn’t exactly true. I’ve seen patients be on syringe drivers for weeks, they’re alert and still eating/drinking etc. Just because someone is started on a syringe driver doesn’t mean that they will pass quickly or that they’re at the very end of life. Sometimes the best way to deliver the medication is via the syringe driver and it allows the patient to stay comfortable. Of course we get patients who are at the end of life who can no longer swallow, which is a progression of their illness, and therefore the syringe driver is best to deliver the medications to avoid aspiration. At this stage we would recommend the patient not eat or drink due to this risk, but promote good oral hygiene to keep the mouth hydrated. Syringe drivers aren’t there to “knock the patient out” either. The aim is to keep the patient comfortable at all times and manage their symptoms. It’s more a progression of the illness and a shutting down of the systems that cause the patient to sleep more etc.
Sorry that was long, I just wanted to address the comments around syringe drivers as some people have the assumption that once they or a loved one are started on it that they’re written off/it’s the very end. Yes they’re used for our palliative patients, but dying is a process and it’s an individual one at that. I wouldn’t like to think people are reluctant to the use of the syringe driver/attach negative connotations to it, because it’s something that can really help a patient on their journey, so hopefully people can take this info forward with them.
