Intravenous dexmedetomidine prolongs bupivacaine spinal analgesia.
BACKGROUND The prolongation of spinal anesthesia by using clonidine through the oral, intravenous and spinal route has been known. The new alpha 2 agonist, dexmedetomidine has been proved to prolong the spinal anesthesia through the intrathecal route. We hypothesized that dexmedetomidine when administered intravenously following spinal block, also prolongs spinal analgesia. METHODS 48 patient...
متن کاملPlain bupivacaine: 0.5% or 0.25% for spinal analgesia?
Plain 0.5% bupivacaine 3 ml was compared with plain 0.25% bupivacaine 6 ml for spinal anaesthesia during transurethral surgery in 40 patients. The solutions were injected over 30 s at the L3/4 space with the patient in the sitting position. The patient was kept sitting for 2 min, supine for 5 min and then placed in the lithotomy position. No significant differences were found in onset time, ext...
متن کاملSpinal analgesia with hyperbaric bupivacaine: influence of age.
The effects of age were investigated on characteristics of spinal analgesia with hyperbaric bupivacaine in 38 younger patients (less than 50 yr: group I), and 48 older patients (greater than 80 yr: group II). Four millilitre of 0.375% bupivacaine in 2.5% dextrose was injected via the L3-4 space in a lateral position, and the patients were immediately turned supine. In group II, the time to maxi...
متن کاملSpinal analgesia with hyperbaric bupivacaine: effects of volume of solution.
The effects of 0.5% bupivacaine 1.5, 2 and 3 ml in 8% glucose was compared in a double-blind study involving 30 patients undergoing spinal analgesia. The time to the onset of maximum segmental spread of analgesia was approximately 15 min for all three volumes. Cephalad spread of analgesia was related to the volume used: 1.5 ml reached T10, 2 ml T8 and 3 ml T7. The duration of analgesia increase...
متن کاملInfluence of obesity on spinal analgesia with isobaric 0.5% bupivacaine.
In an unblinded study 50 patients undergoing cystoscopic procedures received a spinal anaesthetic of plain 0.5% bupivacaine 4 ml administered in the sitting position at the L3-4 space. There was a correlation between the height of blockade assessed by pinprick analgesia and the degree of obesity of the patients measured by weight, weight/height, and weight/height2. Using this dose of spinal ana...
