Randomized Controlled Trial Clinical TrialEffects of fentanyl on pain and hemodynamic response after retrobulbar block in patients having phacoemulsification.
To determine the effects of systemic fentanyl analgesia in preventing the pain related to the administration of retrobulbar anesthesia and cataract surgery. ⋯ The results suggest that fentanyl preemptively decreases injection and intraoperative hyperalgesia and provides hemodynamic stability without affecting patient cooperation, resulting in cataract surgery with retrobulbar anesthesia that is comfortable for both surgeon and patient.

[Peripheral nerve stimulator for femoral nerve block. Is it really necessary?].
There are several methods to locate the femoral nerve in the perivascular inguinal space, being the most common the use of a peripheral nerve stimulator. This study aimed at evaluating femoral nerve block performed with peripheral nerve stimulator as compared to the loss of resistance to air technique, both by single injection or with catheter insertion. ⋯ Whereas the peripheral nerve stimulator is more widely used in the inguinal region, our study has shown that the loss of resistance to air technique is an effective and feasible alternative.

Alemanno's brachial plexus block ten years later: topographic study of the anesthetized areas.
The study analyzes the extension of anesthesia induced by Alemanno's brachial plexus block technique on the various areas of competence of the different nerves. ⋯ Alemanno's technique is recommended for operations on the shoulder and humerus, whereas more peripheral techniques may be preferable for interventions on the forearm and hand.
