Norepinephrine has powerful and diverse modulatory effects on hypoglossal (XII) motoneuron activity, which is important in maintaining airway patency. The objective was to test two hypotheses that alpha2-adrenoceptor-mediated, presynaptic inhibition of glutamatergic inspiratory drive (Selvaratnam SR, Parkis MA, and Funk GD. Brain Res 805: 104-115, 1998) and postsynaptic inhibition of the hyperp...
Sensory neuron types have been distinguished by distinct morphological and transcriptional characteristics. Excitability is the most fundamental functional feature of neurons. Mathematical models described by Hodgkin have revealed three types of neuronal excitability based on the relationship between firing frequency and applied current intensity. However, whether natural sensory neurons displa...
Aims and background: The infraclavicular nerve block as a method for anesthesia or analgesia in upper extremities that can be performed under guide of nerve stimulation or ultrasound. One of the adverse reaction to this method is the local anesthetic systemic toxicity that has been decreased when using the ultrasound to avoid intravascular injection. Case report: This case report explains a...
Introduction: As endotracheal intubation is the first action which must be done for serious and very ill patients , so any procrastination leads to dangerous consequences including aspiration and finally death. Routine method for endotracheal intubation is injection of intravascular diazepam- Pethidine and sometimes muscle relaxants , but these drugs in Patients with GCS under 7 cause more decr...
OBJECTIVE The aim of this study is to compare the effects of parasacral and posterior Winnie approaches when combined with the inguinal paravascular approach for lumbar plexus block. METHODS After the approval of the Ethics Committee, 40 patients scheduled to undergo arthroscopic knee surgery were enrolled. The patients were randomly assigned into two groups in a double-blind manner to perfor...
Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...
