Randomized Controlled Trial Clinical TrialEffects of immediately initiating an epidural infusion in the combined spinal and epidural technique in nulliparous parturients.
Intrathecal fentanyl with bupivacaine provides rapid labor analgesia of limited duration. We investigated the effect of initiating an epidural infusion of 0.1% ropivacaine with fentanyl 2 microg/mL and epinephrine 1:400,000 (REF) on the duration of analgesia and incidence of side effects after intrathecal injection in the combined spinal and epidural technique. ⋯ Initiating an infusion of REF prolongs the duration of analgesia, but also results in a greater decrease in blood pressure. Despite this effect on blood pressure, there was no difference in ephedrine use.

Clinical TrialMyofascial pain in patients with postthoracotomy pain syndrome.
Postthoracotomy pain syndrome is generally considered to be neuropathic pain due to intercostal nerve injury. However, nonneuropathic pain can also occur following thoracic surgery. We present a series of cases with postthoracotomy pain syndrome in which myofascial pain was thought to be a causative component of postthoracotomy pain syndrome. ⋯ Postthoracotomy pain may result, at least in part, from a nonneuropathic origin (myofascial pain). It is recommended that each patient be examined in detail to determine whether there is a trigger point in a taut muscular band within the scapular region. If found, this point is suggested as a good area for anesthetic injection.

Case ReportsComplete brachial plexus palsy after total shoulder arthroplasty done with interscalene block anesthesia.
This report illustrates that brachial plexus palsy can result from either interscalene block or total shoulder arthroplasty. It is often impossible to determine which procedure caused the deficit; therefore, we believe the focus should be placed on treatment of the neurologic deficit. This report provides a suggested algorithm for diagnosis and treatment of postprocedure brachial plexus palsy. ⋯ Proper diagnosis and treatment of postprocedure brachial plexus palsy may improve recovery of function. Several precautions may reduce the likelihood of brachial plexus palsy following interscalene block for total shoulder arthroplasty.

Case ReportsLateral cervical epidural catheter placement for continuous unilateral upper extremity analgesia and sympathetic block.
The use of the laterally directed cervical epidural catheter for the treatment of acute and chronic pain has not been previously described. We have used this technique in a series of 30 patients to produce unilateral upper extremity analgesia and sympathetic block. We present a case report of a patient treated with this technique and a description of the technique and results from the series. ⋯ This case report shows results typical of this series of 30 patients. In this series, the laterally directed cervical epidural catheter was an effective technique to produce continuous unilateral analgesia and sympathetic block. Key Words: Analgesia (epidural), Autonomic nerve block, Reflex sympathetic dystrophy, Postoperative pain.

Case ReportsDetermining epidural catheter location using nerve stimulation with radiological confirmation.
The use of epidural stimulation to confirm epidural catheter placement has been shown. This case report describes the benefits and problems of using the epidural stimulation test to confirm epidural catheter placement and provides supporting evidence for these observations using radiological imaging. ⋯ This report illustrates some of the potential benefits and problems of using the nerve stimulation test to confirm epidural catheter placement, with radiological verification.
