Randomized Controlled Trial Comparative Study Clinical Trial
[Femoral nerve block as pain relief in hip fracture. A good alternative in perioperative treatment proved by a prospective study].
Almost 25% of all patients with hip fracture experience temporary confusion pre- and directly postoperatively due to trauma, advanced age, transport between units, and the use of analgesics, 35-50% of the patients suffer temporary or chronic decubitus. Analgesics often lead to nausea. A femoral nerve block can interrupt sensory impulses from the hip joint and provide complete pain relief without affecting the CNS, thus making preoperative care easier and postoperative rehabilitation can be started earlier. 80 consecutive patients with hip fracture were randomized to femoral nerve block or pharmacological treatment only. ⋯ Femoral nerve block provides adequate pain relief, equivalent to pharmacological treatment in most patients. The time for postoperative mobilization was shorter and less temporary confusion was seen. There were no complications in this group, making nerve block a good alternative to traditional pharmacological preoperative treatment for patients with hip fractures.

Therapeutic selective nerve root block in the nonsurgical treatment of traumatically induced cervical spondylotic radicular pain.
To investigate the outcomes resulting from the use of fluoroscopically guided therapeutic selective nerve root block in the nonsurgical treatment of traumatically induced cervical spondylotic radicular pain. ⋯ These initial and preliminary findings do not support the use of therapeutic selective nerve root block in the treatment of this challenging patient population with traumatically induced spondylotic radicular pain.

Randomized Controlled Trial Clinical TrialPostoperative analgesia in video-assisted thoracoscopy: the role of intercostal blockade.
This study examined (1) the opioid and nonopioid requirement of patients undergoing video-assisted thoracoscopy (VATS) as a measure of postoperative pain and (2) whether percutaneous intercostal blockade might reduce morphine requirements and improve analgesia in VATS procedures. ⋯ Postoperative morphine requirements after VATS surgery are considerable, with pleurectomy being the most painful procedure. Intercostal blockade with bupivacaine provided effective pain relief and a dramatic reduction in morphine requirements. This technique is recommended for VATS surgery, especially if day-case procedures are being contemplated.

Comparative Study
Encapsulation of mepivacaine prolongs the analgesia provided by sciatic nerve blockade in mice.
Liposomal formulations of local anesthetics (LA) are able to control drug-delivery in biological systems, prolonging their anesthetic effect. This study aimed to prepare, characterize and evaluate in vivo drug-delivery systems, composed of large unilamellar liposomes (LUV), for bupivacaine (BVC) and mepivacaine (MVC). ⋯ MVC(LUV) provided a LA effect comparable to that of BVC. We propose MVC(LUV) drug delivery as a potentially new therapeutic option for the treatment of acute pain since the formulation enhances the duration of sensory blockade at lower concentrations than those of plain MVC.

Randomized Controlled Trial Comparative Study Clinical Trial
Increased success rate with infraclavicular brachial plexus block using a dual-injection technique.
To test the hypothesis that dual injection of the local anesthetic in coracoid infraclavicular brachial plexus block might enhance both sensory and motor block for anesthesia of the upper limb when compared with a single-injection technique. ⋯ Dual injection of local anesthetic guided by nerve stimulator increases the efficacy of coracoid block when compared with a single injection of the same dose of local anesthetic.
