CONTEXT Venous outflow from the cranial cavity occurs mainly through the internal jugular vein (IJV). The increase in venous outflow through IJV is possible by head elevation. IJV collapse may indicate the reduction of blood volume in the vein and show the head elevation effectiveness. AIMS The aim of this study is to examine the impact of head elevation(More)
Pharmacological sedation is one of the effective ways of prevention of gag reflex development in patients experiencing anxiety and fright before dental treatment. We are reporting a case where we could successfully eliminate exaggerated gag reflex (intravenous [IV] Gagging Severity Index) in a dental patient using IV sedation with dexmedetomidine. IV(More)
Use of sedation in patients with obstructive sleep apnea (OSA) in dentistry is limited. Hypoxia may develop during medication sleep in dental patients with OSA because of repetitive partial or complete obstruction of the upper airway. In this regard, anesthesiologists prefer not to give any sedative to surgical patients with OSA or support the use of(More)
CONTEXT It is believed that 15°-25° head-down tilt position increases the internal jugular vein cross-sectional area (IJV CSA). The increase in IJV CSA before puncture reduces the risk of its perforation. This pattern was not observed in all patients. We assumed that the absence of respiratory-based IJV excursion is one of the criteria of head-down tilt(More)
Dear Editor, Ultrasound guidance does not always guarantee a successful cannulation and lack of complications.[1] Thus, an ultrasound of the internal jugular vein (IJV) with a maximum diameter of <7 mm is associated with decreased cannulation success.[2] The vein puncture with a small diameter may result in double wall punctures. As a consequence, the(More)
