We studied the peripheral motor axons of the two pyloric dilator (PD) neurons of the stomatogastric ganglion in the lobster, Homarus americanus. Intracellular recordings from the motor nerve showed both fast and slow voltage- and activity-dependent dynamics. During rhythmic bursts, the PD axons displayed changes in spike amplitude and duration. Pharmacological experiments and the voltage depend...

Purpose: to develop objective acoustic criteria of the condition optic nerve and its sheaths for an early diagnosis intracranial hypertension (IH). Material methods. The research involved 24 patients (average age 35.8 ± 8.5 years) with suspected IH. control group consisted 48 healthy subjects 28.5 9.5 years). Ultrasound examination retrobulbar part (ON) included measurement ON thickness (ONSD) ...

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...

case presentation in this report, ultrasound-guided sciatic nerve block was performed in a 25-year-old patient with tetanus to progress his respiratory drive which was decreased due to high dose sedative administration. this procedure accelerates the weaning process and extubation. introduction muscle rigidity and generalized spasm can cause severe pain in patients with tetanus. administration ...

We determined the effects of 10 daily exposures of intermittent hypoxia (IH; 1 h day(-1); oxyhaemoglobin saturation = 80%) on muscle sympathetic nerve activity (MSNA, peroneal nerve) and the hypoxic ventilatory response (HVR) before, during and after an acute 20 min isocapnic hypoxic exposure. We also assessed the potential parallel modulation of the ventilatory and sympathetic systems followin...

conclusions the study indicated advantages of this modified bier's block compared to the traditional one including ability to perform surgery on upper limb bones and considerable pain relief at surgical and tourniquet sites during the operation until one hour thereafter. results this study showed the presence of analgesia at surgical and tourniquet sites during the operation in 96% of patients,...

objectives to compare an out-of-plane interscalene catheter technique to the in-plane technique in a randomized clinical trial. patients and methods eighty-four patients undergoing open shoulder surgery were randomized to either the in-plane or out-of-plane ultrasound-guided continuous interscalene technique. the primary outcome was vas pain rating at 24 hours. secondary outcomes included pain ...

OBJECTIVES To compare the analgesic efficiencies of caudal blocks, ultrasound (US)-guided transversus abdominis plane (TAP) blocks, and ilio-inguinal/ilio-hypogastric (II/IH) blocks performed to provide postoperative analgesia in pediatric patients undergoing unilateral lower abdominal surgery. Methods: This prospective, randomized, single-blinded study was conducted in the Department of Pediat...

The actions of the novel bradycardiac agent ZD7288 [4-(N-ethyl-N-phenylamino)-1, 2-dimethyl-6-(methylamino)pyrimidinium chloride] were investigated on the hyperpolarization-activated cation current Ih and on network activity in spontaneously spindling ferret lateral geniculate (LGNd) slices in vitro using intracellular recording techniques. In voltage-clamp recordings, local application of ZD72...
