Randomized Controlled Trial Comparative Study Clinical Trial
Sciatic nerve blockade improves early postoperative analgesia after open repair of calcaneus fractures.
To determine the effectiveness of analgesia, with or without sciatic nerve blockade, after open repair of calcaneus fracture. ⋯ Sciatic nerve blockade confers significant benefit over morphine alone for analgesia after open repair of calcaneus fractures. Postsurgical sciatic nerve blockade provides the longest possible postoperative block duration.

Randomized Controlled Trial Clinical TrialAnalgesia and discharge following preincisional ilioinguinal and iliohypogastric nerve block combined with general or spinal anaesthesia for inguinal herniorrhaphy.
Preincisional ilioinguinal and iliohypogastric nerve block (IINB) reduces postoperative analgesics after inguinal herniorrhaphy. The effect of an IINB on postoperative pain and discharge profile was therefore studied in day-surgery patients undergoing inguinal herniorrhaphy with general or spinal anaesthesia. ⋯ Only a relatively short immediate analgesic benefit could be demonstrated by a combination of IINB with spinal anaesthesia compared with IINB combined with general anaesthesia. The use of general anaesthesia facilitated an earlier postoperative discharge than spinal anaesthesia.

[Racemic bupivacaine, levobupi vacaine and ropivacaine in regional anesthesia for ophthalmology -- a comparative study].
Racemic bupivacaine, used in peribulbar anesthesia owing to its high potential to promote motor blockade, presents a smaller safety margin for cardiotoxicity in relation to ropivacaine and levobupivacaine. The objective of this study was to compare the degree of motor blockade and alteration of intraocular pressure (IOP) produced by racemic bupivacaine, levobupivacaine and ropivacaine in peribulbar block. ⋯ Considering the advanced age of most of these patients and the high concentrations of local anesthetics used in peribulbar blockade, the use of ropivacaine and levobupivacaine produces motor blockade as effective as racemic bupivacaine while minimising risks for cardiotoxicity.

To evaluate the effectiveness and safety of an orbital block using an ultrashort, wide-bore blunt metal cannula to inject local anesthetic agents into the anterior sub-Tenon's space. ⋯ Effective and predictable ocular anesthesia can be achieved using a blunt, ultrashort cannula for sub-Tenon's block. The technique greatly reduces the risks for globe perforation, muscle damage, and other serious complications.
