Case ReportsA case of delayed emergence from anesthesia caused by postoperative brain edema associated with unexpected cerebral venous sinus thrombosis.
Cerebral venous sinus thrombosis (CVST) is rare but displays various and often dramatic clinical symptoms. Few cases of CVST have been reported in the field of anesthesiology. We encountered an unexpected case of CVST that presented with delayed emergence from anesthesia after resection of a brain tumor. ⋯ A magnetic resonance venogram revealed thromboses in the superior sagittal and straight sinuses. On the 9th postoperative day, the patient died without recovering consciousness or his brainstem reflexes. Anesthesiologists should be aware of CVST as a cause of delayed emergence from anesthesia after craniotomy.

Randomized Controlled TrialMild hypercapnia with hyperventilation attenuates recovery from anesthesia in elderly patients.
Mild hypercapnia with hyperventilation has been reported to significantly decrease recovery time from inhaled anesthesia in young and middle-aged patients. However, its efficacy has not yet been clarified in elderly patients, although delayed emergence can deteriorate their quality of recovery. ⋯ Recovery time was significantly decreased by the ANEclear in the elderly group. This reduction was comparable to the time for middle-aged patients.

Is microvascular decompression surgery a high risk for postoperative nausea and vomiting in patients undergoing craniotomy?
Patients undergoing microvascular decompression surgery often experience postoperative nausea and vomiting (PONV). However, there is little information about the incidence of PONV after microvascular decompression. We hypothesized that microvascular decompression is an especially high-risk procedure for PONV in patients undergoing neurosurgery, and investigated risk factors related to PONV after neurosurgery. ⋯ In this retrospective study, microvascular decompression surgery was an especially high-risk factor for PONV in patients undergoing craniotomy. It may be necessary to adopt a combination of prophylactic methods to reduce the incidence of PONV after microvascular decompression.
