[Effect of dexmedetomidine on anesthetic requirements in cardiovascular surgery].
An anesthetic-sparing effect of dexmedetomidine has been shown in several studies. We investigated the effect of dexmedetomidine on anesthetic requirements in 24 patients undergoing cardiovascular surgery. ⋯ The combined use of dexmedetomidine decreases anesthetic requirements in cardiovascular surgery.

In this article, we describe 14 case reports of using ultrasound guidance to facilitate blockade of the cervical nerve root. ⋯ We conclude that ultrasound guidance might be useful for cervical nerve root blocks by improving nerve and vascular localization, and injections under real-time fluoroscopy might make this block safer by identification of the intravascular injection.

This study aimed to investigate the annual incidence and characteristics of perioperative pulmonary thromboembolism (PTE) in Japan from 2005 through 2007, and to compare the current trend with that observed in our previous studies conducted since 2002. ⋯ The incidence of perioperative PTE and fetal PTE has currently decreased; however, prophylaxis with anticoagulant drugs may have reduced the mortality in some cases.
