Ultrasound guidance for regional anesthesia has gained enormous popularity in the past decade. The usage of ultrasound guidance has reawaken many block techniques in daily clinical practice. In this review, the author described how the ultrasound guidance has changed the manner of intraoperative and postoperative analgesic methods. ⋯ Those success rates increased using sonography, whereas the complications decreased. Advanced sonography shows the clear images of the detailed nerve tissues, so that we can perform the more pin-pointed nerve block considering postoperative benefits of patients. However, it must never be forgotten that both the pre-scan examination before a needle insertion and the continuous watching of an advancing needle tip are essential to perform safer regional anesthesia techniques.

General anesthesia using remifentanil is accompanied with post-operative shivering at a high incidence. Post-operative shivering can be divided into thermoregulatory and non-thermoregulatory. Hypothermia causes thermoregulatory shivering. ⋯ Thus, opioid transition using fentanyl and/or morphine during anesthetic management is essential for the prevention of non-thermoregulatory shivering. It is also reported that magnesium, ketamine and pethidine have preventive effects on non-thermoregulatory shivering. The mechanism underlying post-operative shivering associated with general anesthesia using remifentanil is very complicated; therefore, we speculate that multimodal approach is required for its prevention.

Critical care echocardiography (CCE) using the transthoracic approach is a noninvasive imaging tool at the bedside and is of great value in the intensive care setting because of its portability, widespread availability, and rapid diagnostic capability. Time-dependent scenarios occur during shock and during cardiopulmonary resuscitation. Potentially treatable causes of shock or cardiac arrest including hypovolemia, cardiac tamponade, left ventricular failure, or massive pulmonary embolism should be detected or excluded as soon as possible. ⋯ Competence in basic CCE includes qualitative assessment of left ventricular cavity size, left ventricular systolic function, right ventricular cavity size and function, identification of pericardial fluid, and measurement of inferior vena cava diameter. Basic CCE should be a required part of the training of every ICU physician. This review discusses the application of basic CCE performed by the emphasis on focused or goal-directed assessment.

General anesthesia was successfully performed in an 86-year-old woman with severe tracheobronchomalacia Tracheobronchomalacia in adult is a very rare disease, characterized by weakness of the trachea and bronchi, causing luminal narrowing during expiration. The patient had laparoscopic cholecystectomy. We used propofol, remifentanil, and rocuronium for induction of anesthesia. ⋯ The patient did well, and was discharged from the hospital 3 days after the operation. In this case, no special care such as postoperative CPAP was necessary, but normally, general anesthesia for a patient with tracheobronchomalacia requires attention. We gave general anesthesia satisfactorily in a patient with tracheobronchomalacia.

Comparative Study
[Comparative study of the KingVision videolaryngoscope and Airwayscope using manikins].
KingVision (KV) is a new videolaryngoscope. In this study, we compared the ease of use of the KV with the Airwayscope (AWS) by experienced personnel in a simulated manikin. ⋯ KV may be a suitable device for routine anesthesia care and difficult airway intubation. Further studies in a clinical setting are necessary to confirm these findings.
