background: sore throat is one of the major complications of tracheal intubation after general anesthesia. harpagophytum is an herbal medicine, the anti-inflammatory and analgesic effects of which have been demonstrated in various studies. we studied the effects of single dose harpagophytum one hour before tracheal intubation, to prevent the sore throat after extubation. methods: in a randomize...

introduction: post-operative sore throat and cough are common complications of endotracheal intubation. these conditions may be very distressing for the patient and may lead to unpleasant memories. this study was performed in order to determine whether beclomethasone and lidocaine spray could reduce the frequency of post-operative sore throat and hoarseness after tracheal extubation.  materials...

introduction: presence of a sore throat after surgery is a common side effect of general anesthesia with intratracheal intubation and can cause discomfort for the patient and prolong the recovery process. in this study we compared the effect of dexamethasone before and after intubation on the incidence of sore throat after tympanoplasty surgery.   materials and methods: in a double-blind, rando...

When a sandstone reservoir enters the ultra-high water cut stage, oil phase changes from continuous to discontinuous, which results in difficulties further development and utilization of reservoir. It is important clarify flow law distribution state discontinuous phases guide remaining production. This study selected samples reservoirs, accurately obtained information digital core, constructed ...

Abstract The cosmological perturbations on a bouncing brane are studied. The brane is moving inside a Klebanov-Strassler throat where the infra-red region of the geometry is smoothly cut off. For an observer confined to the world-volume of the brane, this results in a non-singular bouncing mirage cosmology. We have calculated the scalar perturbations corresponding to the normal displacements of...

background: tracheal intubation is used in general anesthesia and often leads to traumatization of the airway mucosa. these complications can cause postoperative morbidity. this study was designed to determine the effect of ketamine spraying on the endotracheal tube cuff on sore throat, cough, and hoarseness during the first 24 hours of the postoperative period. methods: 120 healthy women with ...

Spherically symmetric thin-shell wormholes in the presence of a cosmological constant are constructed applying the cut-and-paste technique implemented by Visser. Using the Darmois-Israel formalism the surface stresses, which are concentrated at the wormhole throat, are determined. This construction allows one to apply a dynamical analysis to the throat, considering linearized radial perturbatio...
