Randomized Controlled Trial
Therapeutic cervical medial branch blocks in managing chronic neck pain: a preliminary report of a randomized, double-blind, controlled trial: clinical trial NCT0033272.
Based on the criteria established by the International Association for the Study of Pain, the prevalence of persistent neck pain, secondary to involvement of cervical facet or zygapophysial joints has been described in controlled studies as varying from 54% to 67%. Intraarticular injections, medial branch nerve blocks and neurolysis of medial branch nerves have been described in managing chronic neck pain of facet joint origin. ⋯ Therapeutic cervical medial branch nerve blocks, with or without Sarapin or steroids, may provide effective management for chronic neck pain of facet joint origin.

The BiP Test: a modified loss of resistance technique for confirming epidural needle placement.
Correct identification of the epidural space minimizes complications and ensures successful epidural blockade. The loss of resistance technique is the most common technique used for identification of the epidural space. However, sometimes loss of resistance occurs when the needle is not actually in the epidural space. The injection in this instance will result in the medication not being deposited in the epidural space. At other times, loss of resistance is not definitive. Further advancement of the needle may predispose to a wet tap. ⋯ This technique adds a useful confirmatory test to the already well-known loss of resistance technique used to verify the position of the epidural needle.

Randomized Controlled Trial Clinical Trial
The value of nerve root infiltration for leg pain when used with a nerve stimulator.
Randomized comparative study of the efficacy of nerve root infiltration (NRI) guided by neurostimulator to find the value of nerve stimulators in nerve root infiltration was undertaken. The response to nerve root infiltration using local anaesthetics and steroid is unpredictable, partly because the exact nerve root giving rise to pain may not be truly infiltrated. The nerve stimulator is advocated to identify the nerve root of concern prior to infiltration. ⋯ When responded there was no significant statistical difference using the Oswestry disability score between both groups. After excluding disc bulge in patients who respond partially to NRI, it is worthwhile repeating the injection. There was a significant difference in response rate when NRI was done under guidance of a nerve stimulator, the stimulator is safe to use and increases the specificity of the block.

Randomized Controlled Trial Comparative Study
Fentanyl and clonidine as adjunctive analgesics with levobupivacaine in paravertebral analgesia for breast surgery.
The addition of fentanyl or clonidine to levobupivacaine was evaluated in patients undergoing breast surgery under general anaesthesia with intra- and postoperative paravertebral analgesia. Patients were randomly allocated to four groups: Group L received 19 ml bolus levobupivacaine 0.25% plus 1 ml saline followed by an infusion of levobupivacaine 0.1%; Group LF received 19 ml bolus levobupivacaine 0.25% plus fentanyl 50 microg followed by an infusion of levobupivacaine 0.05% with fentanyl 4 microg x ml(-1); Group LC received 19 ml bolus levobupivacaine 0.25% plus clonidine 150 microg followed by an infusion of levobupivacaine 0.05% with clonidine 3 microg x ml(-1); Group C (control) received general anaesthesia without paravertebral analgesia. All groups received postoperative i.v. morphine patient controlled analgesia (PCA). Although mean (SD) postoperative PCA morphine consumption was decreased in LF [7.9 (4.1) mg] and LC [5.9 (3.5) mg]vs L [27.7 (8.6) mg] or C patients [21.7 (5.5) mg], p < 0.01, paravertebral fentanyl and clonidine were associated with significantly increased vomiting and hypotension, respectively.

Randomized Controlled TrialCombination of oral tramadol, acetaminophen and 1% lidocaine induced periprostatic nerve block for pain control during transrectal ultrasound guided biopsy of the prostate: a prospective, randomized, controlled trial.
Prostate biopsy for diagnosing cancer can be painful. Tramadol is a centrally acting analgesic used to treat many pain disorders. We determined whether administering oral tramadol and acetaminophen combined with 1% lidocaine induced periprostatic nerve block would significantly decrease the pain experienced by patients during standard 10-core transrectal ultrasound guided needle biopsy of the prostate. ⋯ Administering 75 mg tramadol/650 mg acetaminophen orally with periprostatic 1% lidocaine before transrectal ultrasound guided prostate biopsy is a safe, easy and effective method of controlling pain during the biopsy procedure.
