Case ReportsAccidental subdural injection during attempted lumbar epidural block may present as a failed or inadequate block: radiographic evidence.
Until now, case reports after accidental subdural injection during attempted epidural block have usually described extensive neuraxial blocks with a delayed onset, after low doses of local anesthetic, with a characteristic radiographic appearance on contrast injection. Our radiographic investigation of atypical "epidural" blocks has revealed that subdural injection may go unrecognized clinically and may be a cause of inadequate blocks. The mechanism is explored. ⋯ Accidental subdural injection may now be added to the list of causes of failed or inadequate "epidural" block. Clinicians should be aware of the diagnosis of a possible subdural injection, if a poor quality block with restricted spread and slow onset is associated with pain on postoperative reinjection of the catheter.

To demonstrate the effectiveness of Sarapin in prolonging the action of neural blockade with improved pain relief. ⋯ This prospective, double-blind trial of 500 patients undergoing 828 treatments, one time with Sarapin and a subsequent time without, with each patient acting as their own control, showed no significant differences in the pain relief or duration of significant relief with the addition of Sarapin.

Randomized Controlled Trial Comparative Study Clinical Trial
[Intercostal nerve blockade with alcohol during operation for postthoracotomy pain].
Purpose of this study was to evaluate the effectiveness of intraoperative intercostal nerve blockade with alcohol in addition to epidural analgesia with morphine for control of postthoracotomy pain syndrome. ⋯ Additional intraoperative intercostal nerve blockade with alcohol provides an additional benefit for postthoracotomy pain relief, especially for at least one month following the thoracotomy.

Randomized Controlled Trial Comparative Study Clinical Trial
Epidural block with ropivacaine and bupivacaine for elective caesarean section: maternal cardiovascular parameters, comfort and neonatal well-being.
To determine cardiovascular effects and neonatal outcome of ropivacaine 0.75% and bupivacaine 0.5% for elective epidural caesarean section. ⋯ Both drugs produced equally satisfactory epidural block. Although ropivacaine 0.75% resulted in a greater decrease of maternal heart rate, this effect did not influence neonatal well-being. Both ropivacaine 0.75% and bupivacaine 0.5% can therefore be recommended for epidural anaesthesia in elective caesarean section.

Randomized Controlled Trial Clinical Trial
[Bupivacaine for continuous interscalene brachial plexus analgesia after shoulder surgery].
This study evaluates clinical efficacy of continuous interscalene brachial plexus block with bupivacaine 0.15% for postoperative analgesia after shoulder surgery. ⋯ Continuous interscalene brachial plexus analgesia is a reliable and effective method of providing postoperative pain relief after shoulder surgery and is superior to the systemic analgesia.
