The left superior vena cava (LSVC) is often complicated with congenital heart defect. Although we simply clamp LSVC during cardio-pulmonary bypass (CPB), appropriateness of this technique has not been clarified. We noninvasively evaluate cerebral tissue oxygenation while the clamping of LSVC under CPB by near-infrared spectroscopy (NIRS). ⋯ These data demonstrated that LSVC could be safely clamped when LSVC pressure was under 30 mmHg.

The dual puncture is one of the diseaseful complications at the induction of the epidural anesthesia, which causes severe symptoms of intracranial hypotension such as headache and nausea. The clinical courses of 3 patients with the dual puncture symptoms after pulmonary resections were retrospectively reviewed, and the effect of the continuous epidural saline infusion treatment (CESI) for the dual puncture was evaluated. ⋯ In contrast, the symptoms of the others who were treated with the CESI were quickly recovered or were effectively prevented. This report strongly suggested that the CESI was convenient and effective treatment for dual punctune symptoms by suppressing the cerebrospinal fluid leakage by elevation of the fluid pressure in the extradural space.
