Abstract:
Objective To explore the application of monitored anesthesia care (MAC) under the guidance of bispectral index in surgical treatment of chronic subdural hematoma in elderly patients.Methods Sixty patients (33 males, 27 females, aged 65-85 years, ASA physical status Ⅱ-Ⅳ) undergoing sphenotresia drainage of chronic subdural hematoma from March, 2014 to May, 2015 were randomly divided into BIS-guided monitored care anesthesia group (group M) and local anesthesia group (group C).Propofol and remifentanil were intravenously infused into patients from group M to maintain BIS index 65-75, vital signs stability and no movement.Local anesthesia was performed before skin incision for each patient.The frequency of medication, the incidence of adverse events were record.The satisfied degree of sedation and analgesia were also evaluated.Results The frequency of movement, local anesthesia drug and additional use of esmolol, were significantly less in group M than those in group C.The satisfaction degree of sedation and analgesia were significantly higher in group M than those in group C (P<0.05).There was no significant difference of respiratory depression and airway obstruction between the two groups.No nausea vomiting reflex and respiration occurred in all groups.Conclusion Bispectral index guidance can be safely applied in surgical treatment of chronic subdural hematoma in elderly patients, which can supply more sedative and analgesic satisfaction than local anesthesia.
