Is regional anaesthesia associated with postoperative cognitive deficit? A prospective randomised controlled trial.
Query!
Scientific title
The prospective randomised controlled phase III GRAIL Trial will consider patients receiving general anaesthesia compared to those receiving regional anaesthesia to undergo extracorporeal shock wave lithotripsy for the treatment of kidney stones and will evaluate whether there is any difference in the incidence of postoperative cognitive dysfunction (POCD) in the short and medium term.

Description of intervention(s) / exposure
To study patients undergoing a single surgical treatment: extracorporeal shock wave lithotripsy (ESWL) for treatment of kidney stones. General anaesthesia will consist of routine clinical practice using midazolam/fentanyl/propofol/laryngeal mask/spontaneous respiration of air and oxygen. Regional anaesthesia will conform to current practice consisting of #25 gauge spinal needle and 0.5% heavy spinal marcaine. Patients will complete a neuropyschological test battery preoperatively, 7 days and 3 months postoperatively and a short test version at discharge.
