SPINAL IRRITATION

Transient radicular irritation after spinal anaesthesia with 2% isobaric lignocaine.

A typical case of transient radicular irritation after spinal anaesthesia with 2% isobaric lignocaine is described. The definition and history of this syndrome and the implications of the use of pencil point needles with lignocaine for spinal anaesthesia are discussed.

Spinal procaine with and without epinephrine and its relation to transient radicular irritation.

PURPOSE To document the clinical characteristics of procaine with or without the addition of epinephrine. METHODS In this randomized, prospective, double blind study, 62 patients received spinal anesthesia with 100 mg procaine and either 0.3 mg epinephrine (EPI group) or 0.3 ml NaCl 0.9% (SALINE group). Sensory anesthesia to needle prick was evaluated q 1 min for 10 min, q 3 min for 33 min an...

Sensory irritation: risk assessment approaches.

Irritation of eyes and upper airways--sensory irritation--is commonly used as a parameter for setting occupational exposure limits and is a common complaint in occupants of non-industrial buildings. Sensory irritation occurs from stimulation of receptors on trigeminal nerves. In general, chemically reactive compounds are more potent than non-reactive congeners. Animal studies allow prediction o...
