Comparative Study
Indications for and benefits of lumbar facet joint block: analysis of 230 consecutive patients.
The authors evaluated the effectiveness of using a facet joint block with local anesthetic agents and or steroid medication for the treatment of low-back pain in a medium-sized series of patients. ⋯ Lumbar facet joint block is a minimally invasive procedure to differentiate between facet joint pain and other causes of lower-back pain. The procedure seems to be useful for distinguishing between facet joint pain from postoperative pain due to inappropriate neural decompression after lumbar surgery. It can be also recommended as a possible midterm intervention for chronic low-back pain.

Randomized Controlled Trial Clinical TrialEffect of addition of clonidine to local anaesthetic mixture for peribulbar block.
Clonidine added to local anaesthetics prolongs the duration of anaesthesia and analgesia of peripheral, neuraxial and retrobulbar blocks. The present randomized blinded controlled study was conducted to evaluate the effect of the addition of clonidine to local anaesthetic mixture on the quality, onset time, duration of peribulbar block, perioperative analgesia and patients' comfort. The study comprised two groups of 12 patients each. ⋯ No significant haemodynamic, respiratory or sedative effects were recorded. The perioperative pain scores and the analgesic requirements were significantly (P<0.01) lower in group B patients. We found that addition of clonidine 1 microg/kg to local anaesthetic mixture significantly increases the duration of anaesthesia and analgesia after peribulbar block.

ReviewCervicogenic headache: interventional, anesthetic, and ablative treatment.
Cervicogenic headache is becoming an accepted clinical syndrome in which headache pain is thought to originate from the cervical spine. Unfortunately, there are no diagnostic imaging techniques of the cervical spine and associated structures that can determine the exact source of pain. ⋯ This suggests that consistent reproducible anatomic and neurophysiologic pathways exist for the reproduction of typical clinical pain patterns and the ability of neuroblockade to consistently interrupt these pain pathways. This article describes the essential anatomy required to understand the use of diagnostic nerve blocks, and their predictive value in anticipating response to neuroablative and interventional therapy with a review of the major interventional, anesthetic, and ablative techniques for cervicogenic headache.

Transient femoral nerve palsy following ilio-inguinal nerve blockade for day case inguinal hernia repair.
Transient femoral nerve palsy (TFNP) has been reported in patients undergoing inguinal hernia repair involving the use of ilio-inguinal nerve block. Ilio-inguinal nerve blocks can be administered under vision by the surgeon or by the anaesthetist using a standard blind technique. There has been no study that has specifically examined the incidence of this complication and whether its development is related to the type of method used to administer the block. ⋯ TFNP is a recognised complication following ilioinguinal nerve blockade for inguinal hernia surgery. Our series shows that ilio-inguinal block given under direct vision does not appear to reduce the chance of this complication occurring. This may result from the fact that this complication could be due to local infiltration into the operative field rather than direct infiltration around the femoral nerve. As inguinal hernia repair undertaken as a day case procedure increases, the awareness of this complication is important to avoid morbidity
