Magnetic resonance imaging analysis revealed a significant time-dependent expansion of injectates. Magnetic resonance imaging and the degree of dermatomal anesthesia confirmed that the upper and lateral TAP compartments do not appear to communicate. Separate injections at the upper intercostal and lateral classic TAP plexuses are necessary to block the entire abdominal wall.
A young man was accidentally intoxicated with isobutyl nitrite by a threefold lethal dose. Due to nitrites' ability to change hemoglobine into methemoglobine the patient showed signs of severe hypoxia, which could not be treated by conventional means. Therefore the patient was rapidly transferred to a hyperbaric chamber. The patient was treated with pure oxygen at 283 kPa under which a blood exchange transfusion was performed. The patient fully recovered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
