Prospective Evaluation of Cognitive Outcomes After Anesthesia on Patients in the Beach Chair Position

2016-02-04 18:08:22 | BioPortfolio


The purpose of this study was to use Near Infrared Spectroscopy (NIRS) monitoring on participants undergoing shoulder surgery in the beach chair position to determine cerebral desaturation events and to further determine cognitive changes pre and post surgery using the Mini Mental State Exam.


In this prospective, randomized, controlled study, investigators used a standardized anesthesia protocol to maintain the MAP during surgeries done in the BCP. Investigators hypothesized that, if the MAP was maintained, NIRS monitoring would not change intra-operative anesthesia management and would not affect the post-operative cognitive outcomes of participants undergoing surgery in the beach chair position. Investigators secondarily wanted to document the actual incidence of cerebral desaturation events (CDEs) recorded by NIRS occurring in participants placed in the BCP if the MAP was strictly maintained.

Medical and Biotech [MESH] Definitions

Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.

A genetic process by which the adult organism is realized via mechanisms that lead to the restriction in the possible fates of cells, eventually leading to their differentiated state. Mechanisms involved cause heritable changes to cells without changes to DNA sequence such as DNA METHYLATION; HISTONE modification; DNA REPLICATION TIMING; NUCLEOSOME positioning; and heterochromatization which result in selective gene expression or repression.

Conditions characterized by persistent brain damage or dysfunction as sequelae of cranial trauma. This disorder may result from DIFFUSE AXONAL INJURY; INTRACRANIAL HEMORRHAGES; BRAIN EDEMA; and other conditions. Clinical features may include DEMENTIA; focal neurologic deficits; PERSISTENT VEGETATIVE STATE; AKINETIC MUTISM; or COMA.

The failure to retain teeth as a result of disease or injury.

Abnormal communication between two ARTERIES that may result from injury or occur as a congenital abnormality.
