Randomized Controlled Trial Clinical TrialNo enhancement of sensory and motor blockade by ketamine added to ropivacaine interscalene brachial plexus blockade.
Ketamine can enhance anesthetic and analgesic actions of a local anesthetic via a peripheral mechanism. The authors' goal was to determine whether or not ketamine added to ropivacaine in interscalene brachial plexus blockade prolongs postoperative analgesia. In addition, we wanted to determine the incidence of adverse-effects in patients undergoing hand surgery. ⋯ This study suggests that 30 mg ketamine added to ropivacaine in the brachial plexus block does not improve the onset or duration of sensory block, but it does cause a relatively high incidence of adverse-effects. These two findings do not encourage the use of ketamine with local anesthetics for brachial plexus blockade.

Randomized Controlled Trial Clinical TrialEffect of addition of clonidine to local anaesthetic mixture for peribulbar block.
Clonidine added to local anaesthetics prolongs the duration of anaesthesia and analgesia of peripheral, neuraxial and retrobulbar blocks. The present randomized blinded controlled study was conducted to evaluate the effect of the addition of clonidine to local anaesthetic mixture on the quality, onset time, duration of peribulbar block, perioperative analgesia and patients' comfort. The study comprised two groups of 12 patients each. ⋯ No significant haemodynamic, respiratory or sedative effects were recorded. The perioperative pain scores and the analgesic requirements were significantly (P<0.01) lower in group B patients. We found that addition of clonidine 1 microg/kg to local anaesthetic mixture significantly increases the duration of anaesthesia and analgesia after peribulbar block.

Randomized Controlled Trial Clinical Trial[Efficacy of 1% ropivacaine with and without hyaluronidase for peribulbar block].
To determine whether adding hyaluronidase to 1% ropivacaine without adrenalin enhances peribulbar anesthesia for cataract surgery with phacoemulsification. ⋯ The greater efficacy of a peribulbar block with the addition of 10 U/mL of hyaluronidase to 1% ropivacaine without adrenalin, in comparison to 1% ropivacaine alone, was demonstrated by a lower rate of reinjection and ocular mobility, even though no statistically significant difference in either ocular or palpebral akinesia was found.

Iliohypogastric-ilioinguinal peripheral nerve block for post-Cesarean delivery analgesia decreases morphine use but not opioid-related side effects.
To examine if ilioinguinal-iliohypogastric nerve block could reduce the need for post-Cesarean delivery morphine analgesia and thus reduce the incidence of opioid related adverse-effects. ⋯ A multi-level ilioinguinal-iliohypogastric nerve block technique can reduce the amount of systemic morphine required to control post-Cesarean delivery pain but this reduction was not associated with a reduction of opioid related adverse effects in our study group.

Intraoperative intercostal nerve blockade for postthoracotomy pain.
Epidural analgesia is widely employed as a means to control postthoracotomy pain, but is sometimes inadequate. The purpose of this study is to evaluate the effectiveness of intraoperative, temporary, intercostal nerve blockade in addition to epidural analgesia for control of postthoracotomy pain. ⋯ Additional intraoperative intercostal nerve blockade provides an additive benefit for postthoracotomy pain relief, especially early after operation.
