Anesthesia Key

CLINICAL PEARL In-hospital treatment of TBI should focus on minimizing secondary insults to the injured brain due to hypotension, hypoxemia, hypercarbia, hypocarbia, hyperthermia, intracranial hypertension, seizures, hypoglycemia, and hyperglycemia. A….

FIGURE 28.1 jVO2 flow chart. 2. Elevated SjVO2 is a marker of either luxuriant blood flow (or hyperemia) or diminished ability of the brain tissue to extract oxygen. Hyperemia is…

2. Aortocaval compression occurs at approximately 20 weeks of gestation when the parturient is positioned supine and the gravid uterus compresses both the aorta and inferior vena cava. This makes…
