My reconstruction turned into 4 surgeries, 9 transfusions & a cardiac arrest… I need advice

I am so sorry to hear your story Nisey​   You've been thru the mill, that is for sure.  

Gosh, that's a HUGE number of blood transfusions .... was it due to your low blood pressure?  Did they say what brought it on?

They usually warn you beforehand that any surgery procedure comes with inherent risks .... but you never expect anything to actually happen, that is for sure! 
Did they fully explain to you what brought on the cardiac arrest, other than mentioning the anaesthetic drug (that you'd had before without incident?) 

Have you spoken to your Breast Care Nurse to see if they have heard of others having similar occurrences?   Is she aware of others who've had incidents with that particular surgeon?

I think you'd need to get your head around all the facts before approaching any lawyers.  It would be good if you could somehow get a copy of your hospital file, that is for sure! 

Maybe it was something to do with the drugs used to 'wake you up'?  Are you allergic to anything?  If yes, were they aware of it?

I hope you are recovering well both physically and mentally ..... maybe chat with our helpline, if you'd like a confidential chat with someone?  1800 500 258 (Mon-Fri, 9-5)
Take care
