Plasma concentrations of bupivacaine and two of its metabolites during continuous interscalene brachial plexus block.
An interscalene brachial plexus block was performed via a catheter with 20-28 ml of 0.75% bupivacaine plus adrenaline for surgery of the shoulder region in 12 patients. Constant infusion of 0.25% bupivacaine 0.25 mg kg-1 h-1 was continued for 24 h. During surgery light general anaesthesia, without analgesics, was maintained. Plasma concentrations of total and unbound (free fraction) bupivacaine...
متن کاملInterscalene brachial plexus block for shoulder surgery.
BACKGROUND AND OBJECTIVES To evaluate the efficacy of interscalene brachial plexus block as the primary anesthetic for shoulder surgery, the influence on blood loss, and the rate of complication. METHODS Retrospective review of 676 reconstructive surgical procedures of the shoulder for anesthetic technique (regional or general), regional anesthetic technique (paresthesia versus nerve stimulat...
متن کاملEffect of interscalene brachial plexus block on heart rate variability
BACKGROUND Interscalene brachial plexus block (ISB) may be followed by cardiovascular instability. Until date, there is no clear picture available about the underlying mechanisms of ISB. In this study, we aimed to determine the changes in heart rate variability (HRV) parameters after ISB and the differences between right- and left-sided ISBs. METHODS We prospectively studied 24 patients opera...
متن کاملPersistent phrenic nerve paralysis following interscalene brachial plexus block.
A 60-yr-old man, 160 cm tall, weighing 75 kg, with American Society of Anesthesiologists physical status class II, was admitted for elective right shoulder surgery. His medical history was unremarkable except for recent mild diabetes with no related neuropathy, controlled by diet and glimepiride. Physical examination results were unremarkable, and the results of laboratory studies were all with...
متن کاملInterscalene brachial plexus block. Effects on pulmonary function.
BACKGROUND AND OBJECTIVES The interscalene is one of the most common approaches used in brachial plexus block. However, the association of this approach with the ipsilateral blockade of the phrenic nerve has been demonstrated. The resulting diaphragmatic dysfunction causes changes in lung mechanics, which can be potentially deleterious in patients with limited respiratory reserve. The objective...
