Introduction. Spinal anesthesia is one of the oldest and most commonly used regional techniques. It based on injection a local anesthetic into subarachnoid space, during which there transient interruption impulse conduction in spinal nerve roots. Application anesthesia. The use depends following factors: site surgical procedure, type duration degree necessary relaxation, presence accompanying d...

Identification of the subarachnoid space has traditionally been achieved by either a blind landmark-guided approach or using prepuncture ultrasound assistance. To assess the feasibility of performing spinal anaesthesia under real-time ultrasound guidance in routine clinical practice we conducted a single center prospective observational study among patients undergoing lower limb orthopaedic sur...

We report on an 80-year-old woman who had shunt-responsive idiopathic normal pressure hydrocephalus (iNPH). Her brain MRI showed an initial change in the subarachnoid space (a disproportional narrowing of the subarachnoid space at the cerebral high convexities) at the age of 70 years, followed by enlargement of the ventricles (Evans index: 0.31) at the age of 78. The observation suggests that c...

To test whether modulations of spinal serotonin (5-HT) levels would affect the development of morphine tolerance, we treated rats with either intrathecal 5-HT or 5,7-dihydroxytryptamine (5,7-DHT; a 5-HT neurotoxin) in addition to systemic infusion with morphine (2 mg x kg(-1) x h(-1)). Continuous infusion of 5-HT (10 microg x 6 microL(-1) x h(-1)) into the lumbar subarachnoid space of rats for ...

introduction: endoscopic repair is considered the treatment of choice in cerebrospinal fluid (csf) rhinorrhea. the aim of our study was to analyze the etiopathogenesis of csf rhinorrhea, the outcome of treatment and the causes of failure in a developing-country setting.   materials and methods: a retrospective review of patients treated with endoscopic repair for csf rhinorrhea at a tertiary ca...

OBJECTIVE To investigate motor evoked potentials during short term L-arginine infusion in cerebral vasospasm after experimental subarachnoid hemorrhage. METHODS Three groups were designated for this study: control group, subarachnoid hemorrhage-saline infusion group, and subarachnoid hemorrhage-L-arginine infusion group. A subarachnoid hemorrhage was created by intracisternal injection of aut...

Spinal hematoma is a rare and usually severe neurological disorder that, without adequate treatment, often leads to death or permanent neurological deficit. Epidural as well as subdural and subarachnoid hematomas have been investigated in some studies. A 66-year-old man referred to our hospital because of acute onset paraplegia and incontinency started 3 h before admission. With impression of s...
