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.

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
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.

Patients' experiences with multiple stimulation axillary block for fast-track ambulatory hand surgery.
Ambulatory axillary block by multiple nerve stimulation (MNS) is effective and time efficient, but may be rejected by patients because of block pain. This prospective study assessed patients' anxiety and acceptance of this block, identified which of the components of blocking procedure is most painful (i.v. line insertion, repeated needle passes, local anesthetic injection, or electrical stimulation) and recorded patients' anesthetic preferences for the future hand surgery. ⋯ Fear of block pain is diminished after experiencing the blocking procedure. Electrical stimuli was perceived as painful by 53% of patients, and this pain was more intense than with other block components. The majority of our patients would choose axillary block without sedation for future hand surgery and are satisfied with fast-tracking.

Case Reports
[A case report of hemidiaphragmatic paresis caused by interscalene brachial plexus block].
A 76-yr-old woman was scheduled for left upper extremity orthopedic procedure. Preoperative examinations were within normal limits except forced vital capacity. Interscalene brachial plexus block with 0.25% bupivacaine 15 ml, was performed under general anesthesia. ⋯ A chest X-ray demonstrated the elevation of hemidiaphragm. She was diagnosed as ipsilateral hemidiaphragmatic paresis, treated with oxygen inhalation under deep breathing for approximately one hour, and then transferred to the common ward. We conclude that respiratory movement should be carefully observed following interscalene brachial plexus block especially in geriatric patients.
