OBJECTIVE This randomised, double-blind, parallel group phase II/III study with adaptive two-stage design and interim analysis compared the efficacy and tolerability of spray (containing a Salvia officinalis fluid extract) against placebo in the treatment of patients with acute viral pharyngitis. - STUDY PARTICIPANTS in two study parts, a total of 286 patients with subjective and objective ev...

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...

This paper presents the analysis of a two phase flow ejector for the transcritical CO2 cycle. A detailed simulation model of a two phase flow ejector was developed. A controllable ejector expansion device was designed, constructed, and installed in a transcritical CO2 experimental air conditioning system. System-level experimental results were obtained at different operation conditions and vari...

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...

abstract acute upper airway obstruction (uao) is a life threatening complication that is well recognized after carotid endarterectomy, thyroidectomy and pharyngeal area intervention. it is not widely acknowledged that airway obstruction can occur after cervical spinal fusion surgery which was first described in 1955. there are a number of common postoperative problems which may become apparent ...

OBJECTIVE To investigate the safety and efficacy of Throat Coat) (Traditional Medicinals,) Sebastopol, CA), a traditional demulcent herbal tea, in comparison with a placebo tea in the symptomatic treatment of acute pharyngitis. DESIGN Multicenter, prospective, randomized, double-blinded, placebo-controlled, two-armed, parallel-group clinical trial. SETTINGS Three primary care clinics in Dul...

In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...

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 ...
