Monitored anesthesia care (MAC) refers to a service in which anesthesiologists provide a monitoring of patientsÂ’ vital sign during diagnostic or therapeutic procedures, while administering anxiolytics and analgesics. The demands for MAC during various surgical procedures are increasing at operating room and non-operating room. In this case, MAC was provided with dexmedetomidine during a subxiphoid pericardiostomy. A subxiphoid pericardiostomy is an invasive procedure, and MAC can provide a high degree of satisfaction to patients, surgeons, and anesthesiologists. The Patient State Index (PSI) is less familiar electroencephalographic monitor than the bispectral index (BIS), and there are few reports of PSI in patient who has received MAC. We report the experience of MAC, when using dexmedetomidine and PSI monitoring.
Key words: Conscious sedation, dexmedetomidine, electroencephalography, pericardiostomy
