Brief Summary

The aim of this study is to investigate the relationship between the patient positioning in the beach chair position with consequential arterial pressure changes and their influence on regional cerebral oxygen saturation under two anesthesia techniques, general anesthesia in one group of patients and interscalene block in the second group of patients.

Conditions

Impaired Oxygen Delivery; Cerebral Hypoxia

Keywords

interscalene block, general anesthesia, shoulder arthroscopy, cerebral oxygen saturation, beach chair position

Study Population

patients for elective arthroscopy of the shoulder

You may not qualify if:

• The patients who have refused to take part in the study, patients assessed as ASA III or higher, who have cerebrovascular or coronary disease, coagulopathy, hypersensitivity to local anesthetics or other contraindications to one or the other type of anesthetic techniques All patients in whom the operation lasted less than 20 minutes or longer than 90 minutes, have been also excluded from the study.
