Purpose: To investigatge right-to-left shunt determination in dog lungs under inhalantion anesthesia with non-rebreathing and rebreathing systems and fraction of inspired oxygen (FIO2) of 0.9 and 0.4, respectively. Methods: Two groups of 10 dogs each under inhalation anesthesia with sevoflurane: GI in which it was utilized non-rebreathing semiclosed system and FIO2 = 0.9, and GII in which it wa...

BACKGROUND It is skeptical about cardioprotective property of sevoflurane in patients undergoing noncardiac surgery, especially in the elderly patients with coronary heart disease. We hypothesized that long duration of sevoflurane inhalation in noncardiac surgery could ameliorate myocardial damage in such patients. METHODS This was a randomized, prospective study. One hundred twenty-one elder...

Introduction Intraoral synechia is a rare congenital condition, generally associated with other maxillo-facial malformations. We present a neonate with congenital intraoral bilateral synechia without any other facial anomalies. Case Report In this paper, we present a 19-day-old male neonate with congenital intraoral bilateral synechia without any other facial anomalies. We review the literatu...

Available reports suggest that an anterior mediastinal mass causing more than 50% narrowing of the trachea and compressing the great vessels can cause further narrowing of the airway and cardiovascular collapse after the administration of muscle relaxants. Accordingly, inhalation induction of general anesthesia or awake intubation is used to avoid the use of muscle relaxation. The following two...

BACKGROUND Reduced consumption of inhalation anesthetics can be safely achieved by reducing excess fresh gas flow (FGF). In this study the authors describe the use of a real-time decision support tool to reduce excess FGF to lower, less wasteful levels. METHOD The authors applied a decision support tool called the Smart Anesthesia Manager™ (University of Washington, Seattle, WA) that analyzes...

BACKGROUND The first true demonstration of ether as an inhalation anesthetic was on October 16, 1846 by William T.G. Morton, a Boston dentist. Ether has been replaced completely by newer inhalation agents and open drop delivery systems have been exchanged for complicated vaporizers and monitoring systems. Anesthesia in the developing world, however, where lack of financial stability has halted ...

BACKGROUND Previous study of the diagnostic validity of electroencephalography (EEG) to detect abnormalities in equine cerebral cortical function relied on the administration of various drugs for sedation, induction, and maintenance of general anesthesia but used identical criteria to interpret recordings. OBJECTIVES To determine the effects of 2 inhalation anesthetics on the EEG of healthy h...

Continuous general anesthesia is able to exert an influence on the related molecules expression in central nervous system. In this study, we established a short time isoflurane inhalation SD rat model to explore the effect of isoflurane on regulating the relative genes expression in hippocampus. Ten-week male SD rats were anesthesia inducted for 30min. We obtained rat hippocampus tissues after ...
