Randomized Controlled Trial Comparative Study Clinical Trial
A clinical comparison of psoas compartment and inguinal paravascular blocks combined with sciatic nerve block.
The extent of inguinal paravascular blockade and psoas compartment blockade with sciatic nerve block was evaluated in 60 patients. Volumes of 30 ml and 20 ml 0.35% bupivacaine with 1/200,000 epinephrine were injected for lumbar plexus and sciatic nerve block, respectively. ⋯ Sensory blockade of the lateral femoral cutaneous and obturator nerves was more rapid with psoas compartment block. The study suggests that the psoas compartment block is effective in blocking the femoral, lateral femoral cutaneous and obturator nerves, but the inguinal paravascular block is only effective in blocking the femoral nerve.

A short cut review was carried out to establish whether regional nerve block is better than intravenous analgesia in reducing pain in hip fractures. Altogether 21 papers were found using the reported search, of which four presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these best papers are tabulated. A clinical bottom line is stated.

Clonidine as coadjuvant in eye surgery: comparison of peribulbar versus oral administration.
To determine whether the administration of peribulbar or oral clonidine would enhance analgesia and anesthesia in ophthalmologic surgery. ⋯ Despite the higher intraoperative blood cortisol levels, 30 microg peribulbar clonidine decreased the onset time to anesthesia, while 15 and 30 microg peribulbar clonidine prolonged the time to first rescue analgesics in patients under peribulbar block, without increasing the frequency of adverse effects. Conversely, oral administration of clonidine alone did not enhance anesthesia or analgesia following eye block, suggesting a local mechanism of action of clonidine.
