Surgical Treatment for Primary Brainstem Hemorrhage to Improve Postoperative Functional Outcomes.

Background: It remains controversial whether primary brainstem hemorrhage (PBH) should be managed conservatively or treated promptly by surgical evacuation of the hematoma. In the present study, we discuss 5 cases of PBH that were treated surgically and the ability of surgical management to improve postoperative functional outcomes.

Methods: The 4 patients with pontine and medullary hemorrhage underwent surgery via the lateral or midline suboccipital and trans-rhomboid fossa approach in the half-sitting position.

Improvement of Respiratory Depression in a Patient with Primary Medullary Hemorrhage Following Removal of Hematoma in the Half-sitting Position.

Primary medullary hemorrhage is a rare event that may result in ataxic respiration. Although it remains controversial whether primary medullary hemorrhage should be managed conservatively or surgically, recent advancements in neuroimaging and microsurgical techniques have shown promise for improving outcomes and prognosis following surgery. The present report discusses the case of a 70-year-old woman admitted to our institution due to sudden-onset nausea and vomiting.

Effect of acute hypoxic preconditioning on qEEG and functional recovery after cardiac arrest in rats.

Acute hypoxic preconditioning (AHPC) can confer neuroprotection from global cerebral ischemia such as cardiac arrest. We hypothesize that acute neuroprotection by AHPC will be detected early by quantitative EEG (qEEG) entropy analysis after asphyxial cardiac arrest (aCA). Cerebral ischemia lowers EEG signal randomness leading to low entropy.
