Unilateral spinal anaesthesia with hyperbaric bupivacaine.

Background: The dosage of local anaesthetic and the time the patient must be kept in the lateral decubitus position for a unilateral spinal anaesthesia is not known. The aim of this study was to determine the ideal dosage of hyperbaric bupivacaine and the time required for the lateral decubitus position for a unilateral spinal block.

Methods: Ninety patients who were scheduled to receive spinal block for surgery in the lower extremity were randomised into 9 groups (n = 10).

Biochemical and structural approach to collagen synthesis under electric fields.

The effects of electric fields of different intensities and directions on the collagen synthesis of guinea pigs was studied. The effects of vertical and horizontal electric fields of 1.9 kV/m and 0.

Changes in hydroxyproline levels in electric field tissue interaction.

Guinea pigs when exposed to external electric field (1.9 kV/m) for 9 hrs/day for 3 days registered rise in the levels of hydroxyproline in liver, lung and kidney, suggesting increased synthesis of collagen.
