Background and Aims: Laryngospasm and vomiting occurring after tracheal extubation in children is potentially dangerous. The aim of this study was to investigate the effects of preoperative 0.5 mg/kg i.v. Dexamethasone on the incidence of postextubation laryngospasm, and vomiting in children after tonsillectomy. Material and Methods : This study was performed at the Ilam Imam Khomeini hospital,...

we present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound – guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied. it too...

By optimizing the inversion time of a 3D inversion-recovery turbo spin-echo sequence at 3T, we obtained separate images of endolymphatic and perilymphatic space 24 hours after intratympanic administration of gadolinium contrast material. In patients with Ménière disease, endolymphatic hydrops were detected not only in the cochlea but also in the vestibule. Fusion of the 2 types of images visual...

Intratympanic drug delivery refers to drug administration in the middle ear, the main advantage being direct diffusion of substances in the inner ear through the round window membrane with subsequent high intralabiryntine drug concentration and very low systemic side effects. The article is a review of literature concerning the inner ear barrier systems, the physiology of inner ear fluids, intr...

this study aimed to compare the efficacy of dexamethasone and hydrocortisone in the treatment of acute paediatric asthma. forty seven asthmatic children were randomised to receive either dexamethasone (0.6 mg/ml, maximum 16 mg) in a single dose or hydrocortisone (8-10 mg/kg/day) in 4 equal doses for 2 days. our findings showed that the mean length of hospitalization in children receiving dexame...

Objective(s) The aim of this study was to evaluate the effects of dexamethasone on striatal dopaminergic, glutamatergic and gamma amino butyric acid (GABA) ergic neurotransmission in normal and parkinsonian rats. Materials and Methods Dexamethasone (0.15, 0.30, 0.60 and 0.8 mg/kg) was administered to normal or parkinsonian rats (i.p.) followed by the analysis of the striatal neurotransmitter...
