Sedation depends on the level of sensory block induced by spinal anaesthesia.

چکیده
We have investigated the relationship between the extent of spinal block and occurrence of sedation. In a first series of 43 patients, the distribution of sedation score (measured on the Ramsey scale) was related to the extent of spinal block (pinprick). In a second series of 33 patients, the relationship between sedation score and spinal block persisted after injection of midazolam 1 mg. This study confirmed that high spinal block was associated with increased sedation.

Block-dependent sedation during epidural anaesthesia is associated with delayed brainstem conduction.
BACKGROUND Neuraxial anaesthesia produces a sedative and anaesthetic-sparing effect. Recent evidence suggests that spinal cord anaesthesia modifies reticulo-thalamo-cortical arousal by decreasing afferent sensory transmission. We hypothesized that epidural anaesthesia produces sensory deafferentation-dependent sedation that is associated with impairment of brainstem transmission. We used brains...
متن کاملBispectral index is related to the spread of spinal sensory block in patients with combined spinal and general anaesthesia.
BACKGROUND A relationship between the depth of sedation as measured by the bispectral index (BIS) and spinal sensory block height in patients with light to no additional sedation has been described previously. The present study was designed to investigate the hypothesis that BIS values closely correlate with the spread of spinal sensory block in patients deeply sedated with an i.v. target-contr...
متن کاملA Comparative Prospective, Randomised, Double Blind Study of the Effect of IV Dexmeditomidine on Subarachnoid Block Versus 0.9 % Normal Saline as Control
The objective of the study was to evaluate the effect of intravenous dexmedetomidine on the duration of subarachnoid block, hemodynamic changes and sedation in patients undergoing surgeries under spinal anaesthesia with 0.5% of hyperbaric bupivacaine. It was a prospective randomised controlled double blind trial.100 ASA physical status I/II patients undergoing elective surgeries under spinal an...
متن کاملComparison of Spinal Anesthesia in L3-L4 and L4-L5 on Sensory-Motor Block Level and Hemodynamic Status in Cesarean Section
Background and Objective: The injection site in spinal anesthesia is one of the factors that can affect the height of the sensory block. This clinical trial study aimed to compare the effect of spinal anesthesia at L3-L4 and L4-L5 on the level of sensory-motor block and hemodynamic status in cesarean section. Materials and Methods: Seventy patients undergoing elective cesarean section and rece...
متن کاملInfluence of the baricity of a local anaesthetic agent on sedation with propofol during spinal anaesthesia.
BACKGROUND This study examined the effect of different levels of spinal anaesthesia, induced by solutions of different baricity but containing the same amount of local anaesthetic agent, on the requirement for sedation with propofol. METHODS Thirty-six patients undergoing varicose vein surgery under spinal anaesthesia were randomly allocated to receive tetracaine 15 mg in 3 ml of either gluco...
