Brief Summary:
The beach chair position BCP combined with deliberate hypotension impair cerebral perfusion pressure and oxygenation during arthroscopic shoulder surgeries and produce cerebral ischemia
Detailed Description:
Arthroscopic diagnosis and treatment of shoulder disorders have replaced open procedure as the primary treatment method The beach chair BCP and lateral decubitus LDP positions are both considered as reliable techniques for performing effective arthroscopic shoulder surgeries The usage of BCP for shoulder arthroscopic operations started from early 1980s
The advantages of BCP include lack of brachial plexus strain good intra-articular visualization with the ease of conversion to an open approach if required
The BCP combined with deliberate hypotension has been used to decrease intraoperative blood loss and allow a relatively blood-free surgical field However this combination has the risk to impair cerebral perfusion pressure and oxygenation during surgery and produce cerebral ischemia
Lidocaine a commonly used local anesthetic and class IB antiarrhythmic drug that readily crosses the blood - brain barrier Evans et al initially reported cerebral protection of lidocaine in a feline model of cerebral arterial gas embolism Later on the effects of lidocaine on perioperative neuroprotection were detected However the mechanisms underlying lidocaine treatment-induced neuroprotection remain incompletely understood
Lidocaine may provide cerebral protection through many mechanisms including decreasing the cerebral metabolic rate decelerating the ischemic transmembrane ion shift and reducing the ischemic excitotoxin release
