Case Reports
[A case of postoperative convulsive seizure following tranexamic acid infusion during aortic valve replacement].
We present a case of postoperative convulsive seizure in an 84-year-old man who underwent an aortic valve replacement. The patient had hypertension associated with hyperaldosteronism and chronic interstitial nephritis. The duration of cardiopulmonary bypass was 74 min. ⋯ The blood sugar, sodium, and calcium levels were within the normal limits. The seizures were likely due to a total dose of 8 g of tranexamic acid (TXA) administered intraoperatively. Possible mechanisms of TXA-induced seizures include blockage of inhibitory cortical y -aminobutyric acid-A receptors.

GlideScope Cobalt video laryngoscope is a novel indirect laryngoscope for tracheal intubation. It consists of a reusable high-resolution miniature video camera and light source, and a disposable transparent sheath that enshrouds the video camera, thereby preventing contact with the patient. To evaluate the per- formance of GlideScope Cobalt, endotracheal intubation was performed in 100 consecutive patients requiring tracheal intubation for surgery. ⋯ GlideScope Cobalt provided Cormack-Lehane grade 1 or 2 visualization of the glottis in 100 patients. It was easily handled not only by experienced anesthetists but also by novice personnel. GlideScope Cobalt could be an effective aid to airway management in surgical patients.

We report a case of awake intubation in a patient with a difficult airway combined with severe hemorrhagic shock using the Pentax-AWS Airwayscope (AWS). A 65-year-old man experienced severe hemorrhagic shock due to diaphragmatic hernia after extrapleural pneumonectomy and was scheduled for emergent exploratory thoracotomy under general anesthesia. ⋯ The patient underwent awake intubation with the AWS under dexmedetomidine sedation and lidocaine spray for laryngotracheal anesthesia. The patient did not buck during intubation and hemodynamic changes were minimal.

After introducing "BOKUTOH enhanced recvery after surgery (ERAS)" protocol for colorectal surgery in our hospital, the hospital stay after surgery was reduced from 10 days to 7. However, the patients' quality of life (QOL) throughout the perioperative period was not quantified. We assessed the QOL of these patients by using QoR-40J and SF-36v2J (Japanese versions of QoR-40 and SF-36v2) questionnaires. ⋯ Under "BOKUTOH ERAS" protocol management, patients who had had colorectal surgery were able to recover their QOL within 6 days. Thus, leaving hospital by 7 days after surgery was appropriate to our patients.

Ultrasound guided neuraxial block or central venous puncture is now becoming popular in our anesthesia practice to reduce the risk of complications. Pneumothorax is a rare, but possible complication related to these interventions even if the ultrasound is used. However, the pneumothorax itself can also be diagnosed by the ultrasound. We therefore examined the efficacy of ultrasound for diagnosing pneumothorax during lung surgery requiring one lung ventilation. ⋯ Among six ultrasonic lung findings, lung sliding and M-mode procedure are most useful as screening methods of differentiating a pneumothorax.
