Im just back from knee surgery, an arthroscope to my left knee, which seems to have gone well, I am OK to walk without crutches
my hospital encourages CPAP users to take and use their machines although mine wasnt available in the recovery area although I was always awake there so it wasnt needed
since I have no private insurance, and due to my sleep apnea, and the fact that the knee pain varied, there was a wait of several years for the surgery
originally I was OK for an arthroscope under a general anasthetic and the forms for me to fill out did not ask about any sleep apnea or breathing problems, they only found out about my apnea by chance and cancelled, as the hospital didnt have any respiration equipment in case I stopped breathing
I was placed on another surgery list with a 3 year waiting list.
I humbly complained that the internet mentioned arthroscopes being done under local anasthetics, which seemed the answer to my problems but this was rejected
later I asked an eminent arthritus surgeon about this possibility but he said it would be too difficult with mechanical traction needed to stretch the leg to make more space available in the knee joint.
this was despite the internet mentioning the use of compressed gas to expand the joint
So I eventually went to the large city hospital assuming a general anasthetic was essential, only to be assured by the anasthesist that a local or spinal anasthetic was quite OK and would be used because of my apnea, so I was awake but comfortable during the entire procedure and recovery period.
at this hospital they use compressed water to expand the joint and to make enough working space
this is my experience in australia, other countries may vary but it does seem that that more effort needs to be made to encourage the use of local anasthetics for CPAP users whenever possible, especially at smaller hospitals where specialised recussitation equipment and staff may not be available
later i now realise I posted this on the wrong forum but it may interest some, as I was a cronic and severe anxiety and panic attack sufferer for 20 years and it just shows what recovered agoraphobia sufferers can cope with, I took no tranquillisers at all, except for a few sleeping pills for my cronic insomnia
I know of another recovered agoraphobic who conducts and leads a marching band on ceremonial parades, with EVERYONE looking at him
