Randomized Controlled Trial Comparative Study Clinical Trial[Sufentanil vs morphine combined with ropivacaine for thoracic epidural analgesia in major abdominal surgery].
Pain, postoperative ileus, nausea, vomiting are the universal complications after major abdominal surgery. The aim of this study was to assess pain relief, side effects and recovery of gastrointestinal function during epidural analgesia with ropivacaine plus sufentanil and ropivacaine plus morphine after major abdominal surgery. ⋯ Continuous administration of epidural ropivacaine combined with sufentanil or with morphine resulted in good analgesia. Epidural analgesia with ropivacaine plus sufentanil provided the best balance of analgesia, side effects and recovery of gastrointestinal function.

Lumbar plexus and sacral plexus are responsible for sensory and motor innervation of the whole inferior limb and their blockade can be used as a single technique or integrated with general anaesthesia for hip-, femur-, knee-, lower leg-, ankle- and foot surgery. For the performance of the blocks, knowledge of peripheral and central percourse of the nerves and their anatomical relationships to bone-, muscle-, vessel and skin structures is important. In case of the sciatic nerve, a cutaneous projection of the percourse of the nerve is possible (the so-called sciatic line) formed by a virtual line from the midpoint of the line between great trochanter and ischial tuberosity to the apex of the popliteal fossa. ⋯ Regarding the last one, the following approaches are possible, depending on the anatomical site of performance: classic proximal posterior block, parasacral proximal block, lithotomic posterior proximal block, subgluteal posterior proximal block, anterior proximal block, lateral medio femoral popliteal proximal block, block distal from the poplitea, subcalcaneal block. The terms distal and proximal are in relation to the small trochanter. All blocks have to be performed using a nerve stimulator, teflon insulated needles of various measures depending on the kind of block, variable stimulation from 1,5 mA (when evoking muscle contraction) to 0,5-0,3 mA (injection of local anaesthetic) with frequencies of 2 Hz/0,1 ms.

Over the past few years, increasing emphasis has been placed on the need to improve the management of acute pain. Despite a growing trend in acute pain management, many difficulties are still present for the treatment of postoperative pain. Loco-regional techniques together with an effective pain management should accelerate rehabilitation, decrease risk of postoperative complications and speed return to normal activities. ⋯ Rofecoxib showed a reduction of morphine consuming after spinal fusion and has been admitted by FDA for the treatment of post operative pain. Newer methods of pain relief, as patient controlled analgesia (PCA), can provide excellent and safe pain relief. When high-tech options such as PCA are used, patients need a management by an anesthesiologist-based acute pain service (APS), allowing a better pain relief with less side effects compared to patients supervised by less experienced medical staff.

Randomized Controlled Trial Comparative Study Clinical Trial[Cervical plexus block and continuous cervical peridural block with ropivacaine for carotid surgery: a comparison between the 2 methods].
To evaluate the efficacy and security of the cervical plexus block and the continuous cervical peridural anaesthesia in carotid surgery, using ropivacaine as local anaesthetic. ⋯ cervical plexus block and continuous cervical peridural anaesthesia performed with ropivacaine are both effective for anaesthesia in carotid surgery. Ropivacaine, for its minor cardiotoxicity, yields eventual complications related to the two methods, less severe.

Peripheral neural blockade techniques are commonly used procedures to provide perioperative anesthesia and analgesia. Several continuous infusion catheter techniques have been described to extend the use of peripheral neural blockade into the postoperative period as an effective method of providing pain management. The analgesic benefit of continuous local anesthetic peripheral block in the management of postoperative pain is primarily related to the properties of providing intense analgesia thereby reducing perioperative opioid requirements and opioid-related side effects and promoting early recovery of postoperative activity. ⋯ The sciatic nerve is the largest nerve in the body and it lies deep in the posterior thigh. According to its anatomy, the sciatic nerve can then be reached at different levels from the parasacral space to the popliteal fossa, ideally identifying a sciatic line running from the inferior border of the gluteus maximus muscle between the greater throcanter and the ischiatic tuberosity to the popliteal fossa. A variety of continuous peripheral blocks have been described in this paper including continuous sciatic block at several levels (para-sacral nerve block, subgluteal sciatic nerve block) and popliteal nerve block.
