Randomized Controlled Trial Clinical Trial
Plasma concentration of ropivacaine after intercostal blocks for video-assisted thoracic surgery.
Absorption of local anaesthetics following intercostal blocks is rapid. Therefore, plasma concentrations of ropivacaine during intercostal blocks with ropivacaine 2, 5, 7.5 and 10 mg ml-1 (ropivacaine 5 ml injected into each of four intercostal spaces) in patients undergoing video-assisted thoracic surgery were determined. ⋯ After intercostal blocks the absorption of ropivacaine is rapid compared with other techniques for regional anaesthesia and results in relatively high venous and arterial plasma concentrations, especially if a dose of 100 mg or more is used.

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 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.
