Sevoflurane suppresses hypoxia-induced growth and metastasis of lung cancer cells via inhibiting hypoxia-inducible factor-1α.
Hypoxia promotes the progression of lung cancer cells. Unfortunately, anesthetic technique might aggravate hypoxia of lung cancer cells. Sevoflurane is a commonly used anesthetic. Its effect on hypoxia-induced aggressiveness of lung cancer cells remains unknown. The aim of the study is to investigate the effects of sevoflurane on hypoxia-induced growth and metastasis of lung cancer cells. As hypoxia-inducible factor-1α (HIF-1α) plays a pivotal role in mediating the adaptation and tolerance of cancer cells under hypoxic microenvironment, the role of HIF-1α in the effect of sevoflurane on hypoxia-induced growth and metastasis has also been elucidated. ⋯ Sevoflurane could suppress hypoxia-induced growth and metastasis of lung cancer cells, which might be associated with modulating HIF-1α and its down-stream genes. Moreover, p38 MAPK signaling pathway was involved in the regulation of HIF-1α by sevoflurane.

Randomized Controlled Trial Comparative StudyFace-to-face tracheal intubation in adult patients: a comparison of the Airtraq™, Glidescope™ and Fastrach™ devices.
Airway management in emergency settings can be difficult due to limited access to the patient. The use of video laryngoscopes along with the Fastrach™ device improves tracheal intubation; however, the use of such devices in a face-to-face intubation model has not been evaluated in adult patients. ⋯ The Airtraq™ device provided faster insertion and intubation times and enabled better Cormack-Lehane grades. Additionally, the Airtraq™ device required the minimum number of optimization maneuvers and was associated with fewer complications and fewer intubation attempts than the Glidescope™ and Fastrach™ devices during face-to-face tracheal intubation.

ReviewAnesthetic management of pediatric patients with Sturge-Weber syndrome: our experience and a review of the literature.
Sturge-Weber syndrome (SWS) is a rare sporadic congenital neurocutaneous syndrome which is characterized by vascular malformation involving the brain, face and eye. The anesthetic management is complicated by its localized as well as systemic manifestations, associated anomalies and difficult airway due to the presence of angiomas of the oral cavity and airway. We retrospective analyzed the perioperative anesthetic management of children with SWS undergoing ophthalmic surgery and reviewed the literature. ⋯ Preoperative evaluation with airway assessment should be performed with the knowledge of local and systemic manifestation of the syndrome. Proconvulsant and anticonvulsant properties of the anesthetics, as well as drug interactions of antiepileptic medications should be considered when planning anesthesia. Avoiding a rise in intracranial and intraocular pressures, vigilant intraoperative monitoring and postoperative care are the key for conducting safe anesthesia in these children. For ophthalmic procedures, LMAs can be used for airway maintenance with minimal complications in children with SWS.
