Totally agree Grannyrebel7 I watch all these programmes as I have a health service back ground including working in theatres.
The efforts that are made these days thanks to modern technology etc. are truly amazing - I watched one episode a while age where about six or seven different specialists were involved as the patient had multi-problems.
I know there are faults in our NHS and sadly it is badly abused by some people but I honestly can say that I believe we are so lucky.
Keep watching them - they may seem frightening but you will see the amazing results in so many cases.
