Randomized Controlled Trial Comparative Study Clinical TrialInterscalene brachial plexus block is superior to subacromial bursa block after arthroscopic shoulder surgery.
Arthroscopic shoulder surgery is often associated with severe postoperative pain. The results concerning subacromial bursa blockade (SUB) as a method of pain relief have been contradictory. We hypothesized that a SUB and interscalene brachial plexus block (ISB) would similarly reduce early postoperative pain and the need for oxycodone as compared to placebo (PLA). ⋯ After arthroscopic shoulder surgery SUB has a minor effect only on postoperative analgesia, whereas an ISB with low-dose ropivacaine effectively relieves early postoperative pain and reduces the need for opioids.

Randomized Controlled Trial Clinical Trial
Periprostatic nerve block gives better analgesia for prostatic biopsy.
To prospectively compare two local anaesthetic techniques for prostatic biopsies, which are usually taken with no anaesthesia; because multiple biopsy techniques are becoming more common and there is an increasing need for analgesia/anaesthesia during the procedure. ⋯ A periprostatic nerve block with 1% lignocaine was associated with significantly less pain during prostatic biopsy than was rectal lignocaine gel or placebo.

Accidental intrathecal injection of bupivacaine during epidural analgesia in labour remains a hazard, with the potential to cause total spinal anaesthesia and maternal collapse. Sacral block appears early after intrathecal injections compared with epidural ones, and we therefore used SI motor block to determine a safe and reliable test dose for epidural catheter misplacement. ⋯ We conclude that testing for SI motor block 10 min after epidural injection of bupivacaine 10 mg is a reliable test to detect accidental intrathecal injection in the obstetric population.

Case ReportsPresacral neurolytic block for relief of pain from pelvic cancer: description and use of a CT-guided lateral approach.
A CT guided lateral approach for neurolysis of the presacral plexus is described for treatment of pelvic pain due to advanced cancer. The technique was evaluated in two patients with unrelieved pelvic and perineal pain. Other neurolytic techniques used to treat pelvic pain due to advanced cancer are reviewed with a discussion of benefits and potential side effects of this technique.

A new posterior approach to the sciatic nerve in the subgluteal region was developed. We describe our clinical experiences on 135 consecutive patients. ⋯ The study demonstrated that the sciatic nerve can be easily blocked using this new posterior subgluteal approach, suggesting that it represents a safe and effective alternative to block the sciatic nerve at a proximal level, with the potential for reducing the discomfort experienced by the patient during block placement.
