RESUMO
Contralateral acute subdural hematomas that occur during removal of brain tumors under general anesthesia are extremely rare, and there are no reports of this developing during awake craniotomy for brain tumors. We report a case of a 12-year-old boy who complained of sudden and severe headache and nausea around the completion of removal of a glial tumor of the frontal lobe under awake anesthesia. Postoperative computerized tomography scan revealed the presence of contralateral acute minimal subdural hematoma. We suggest that during craniotomy with awake anesthesia for brain tumors, contralateral acute subdural hematoma may occur, even in the absence of brain bulging or changes in vital signs. Sudden intra-operative headache and nausea should be investigated by immediate postoperative computerized tomography scans to ascertain diagnosis.

Vagal reflex during laryngosopy and tracheal intubation may result in cardiac arrhythmia such as bradyarrhythmia and asystole. A 66-year-old woman, scheduled for coronary artery bypass surgery, received intravenous bolus of midazolam 2 mg, sufentanil 50 microgram, and vecuronium 10 mg for induction of general anesthesia. After two minutes of manual ventilation, tracheal intubation was attempted and the patient became asystolic during laryngoscopic manipulation. The laryngoscope was immediately withdrawn, and the patient returned to normal sinus rhythm. Ten minutes later, more experienced practitioner performed the second laryngoscopic intubation, but it eventually induced asystole again. External cardiac massage was commenced and normal sinus rhythm retuned at a rate of 60 beats/min after 1-2 minute later.
