Case Reports[Sciatic, femoral and cutaneous nerve block for arthroscopic meniscectomy in a patient with Eisenmerger's syndrome. Case report].
The principal complication to prevent in Eisenmerger disease with left-right shunt during surgery decreasing of systemic pressure with reduction of pulmonary perfusion and break-down of central oxigenation. A 32 ys old male patient (ASA risk 3) to undergo an extirpation of meniscus by arthroscopic surgery, suffering from Eisenmerger's syndrome with left-type only ventricle, diagnosed when he was 3 ys old and but no repaired by any operation. We performed a sciatic, femoral and lateral cutaneous of thigh nerves block with ropivacaine, that consents a prolonged antalgic effect in postoperative period with minimizing of systemic and pulmonary hypotension risk compared to general, epidural or spinal anaesthesia. Basing on our experience and literature references we think that the anaesthesiological technique with the lowest risk for lower limb surgery in Eisenmerger's syndrome is truncular block.

To reassess reference values for the components of the electrically induced blink reflex, document reference values for facial motor nerve conduction velocity, and demonstrate usefulness of the blink reflex as a diagnostic tool in peripheral facial and trigeminal nerve dysfunction in horses. ⋯ Reference values for the components of the blink reflex and facial motor nerve conduction velocity will allow application of these tests to assist in the diagnosis of equine neurologic disorders involving the trigeminal and facial nerves, the brainstem, and the cranial end of the cervical segment of the spinal cord. This study reveals the usefulness of the blink reflex test in the diagnosis of peripheral trigeminal and facial nerve dysfunction in horses.

Randomized Controlled Trial Comparative Study Clinical TrialAxillary brachial plexus block with ropivacaine 7.5 mg/ml. A comparative study with bupivacaine 5 mg/ml.
Ropivacaine is less cardiotoxic than bupivacaine and may be used in higher doses in order to increase the quality of a block. The aim of this study was to compare the efficacy and safety of 40 ml ropivacaine 7.5 mg/ml (300 mg) and 40 ml bupivacaine 5 mg/ml (200 mg) for axillary plexus block. ⋯ Ropivacaine 7.5 mg/ml, 40 ml, produces axillary plexus block of similar onset and duration but better quality than 40 ml of bupivacaine 5.0 mg/ml.

Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine in peribulbar block: a comparative study with bupivacaine.
Ropivacaine is a new local anesthetic with alleged lower systemic toxicity and slightly lower potency as compared with bupivacaine. The present study aimed to evaluate the efficacy of ropivacaine in peribulbar block, as compared with that of bupivacaine. ⋯ Both local anesthetics were effective in inducing peribulbar block for intraocular surgery. A tendency was noted to a faster onset of peribulbar block with ropivacaine; nevertheless, both drugs had a high degree of success for this block.
