Comparative evaluation of midazolam and butorphanol as oral premedication in pediatric patients.
To compare oral midazolam (0.5 mg/kg) with oral butorphanol (0.2 mg/kg) as a premedication in 60 pediatric patients with regards to sedation, anxiolysis, rescue analgesic requirement, and recovery profile. ⋯ Oral butorphanol is a better premedication than midazolam in children in view of its excellent sedative and analgesic properties. It does not increase side effects significantly.

Preventive analgesia: Effect of small dose of ketamine on morphine requirement after renal surgery.
N-methyl D-Aspartate (NMDA) receptors seem to be responsible for pain memory and their blockade can contribute significantly in prevention of pain. This study was conducted to evaluate the preventive effect of small dose of ketamine, a NMDA receptor blocker, given before skin incision in renal surgery, with the aim to compare analgesic efficacy, intra operative and post-operative side effects. ⋯ Our results demonstrate that small dose of ketamine decreases post-operative pain, reduces morphine consumption, and delays patients request for analgesia beyond the clinical duration of action of ketamine after open renal surgery.

The analgesic efficacy of peritubal infiltration of 0.25% bupivacaine in percutaneous nephrolithotomy - A prospective randomized study.
Percutaneous nephrolithotomy is a routine endourologic procedure in patients with renal stones. Although it is less painful than open surgery, good postoperative analgesia is required to alleviate pain around nephrostomy tube. ⋯ Peritubal infiltration of 0.25% bupivacaine is efficient in alleviating postoperative pain after PCNL.

Combined spinal epidural and epidural volume extension: Interaction of patient position and hyperbaric bupivacaine.
Previous trials have documented failure of block augmentation with epidural volume extension, when applied after the intrathecal injection of hyperbaric bupivacaine was made in sitting position. However, there is no study comparing the effect of change in patient position during block performance, on the results of epidural volume extension. ⋯ If epidural volume extension is being applied with intention of rapid extension of sensory block when hyperbaric bupivacaine has been injected intrathecally, the combined spinal epidural block should be performed in lateral position rather than in the sitting position.

Comparative study of intrathecal dexmedetomidine with intrathecal magnesium sulfate used as adjuvants to bupivacaine.
No drug, used as adjuvant to spinal bupivacaine, has yet been identified that specifically inhibits nociception without its associated side-effects. ⋯ It was found that onset of anesthesia was rapid and of prolonged duration in the dexmedetomidine group (D). However, in the magnesium sulfate group (M), although onset of block was delayed, the duration was significantly prolonged as compared with the control group (C), but to a lesser degree than in the dexmedetomidine group (D). The groups were similar with respect to hemodynamic variables and there were no significant side-effects in either of the groups.
