Ultrasound-guided paravertebral block using an intercostal approach.

30 Oct 2009 We describe an ultrasound-guided technique of continuous bilateral paravertebral block using an intercostal approach in 12 patients undergoing elective abdominal surgery. Postoperatively, each of the patient's paravertebral catheters was bolused ... Read more...

Ropivacaine spinal anesthesia is not antagonized by ondansetron pretreatment.

30 Oct 2009 BACKGROUND: We investigated a possible effect of ondansetron on the duration of sensory and motor block produced by ropivacaine. METHODS: Fifty male patients undergoing transurethral surgery received either 8 mg oral ondansetron the evening before ... Read more...

An ultra-low dose of naloxone added to lidocaine or lidocaine-fentanyl mixture prolongs axillary brachial plexus blockade.

30 Oct 2009 INTRODUCTION: In this prospective, randomized, double-blind study, we evaluated the effect of an ultra-low dose of naloxone added to lidocaine and fentanyl mixture on the onset and duration of axillary brachial plexus block. METHODS: One hundred ... Read more...
