We conclude that 0.25% levobupivacaine and 0.25% bupivacaine have similar motor and sensory block onset times and qualities when used in posterior approach interscalene brachial plexus block, and provide comfortable anesthesia and analgesia for shoulder surgery.

The result of the study show that the extra-slow injection of hyperbaric bupivacaine provided strictly unilateral sensorial and sympathetic block in 93.9 and 87.9% of the patients, respectively, and that a slow injection of low doses of hyperbaric 0.5% bupivacaine 1 ml was sufficient to provide unilateral spinal anesthesia.

BackgroundSystemic sclerosis (SSc), a progressive disease characterized by excessive accumulation of connective tissue components. Although most patients have long survival, some of them progress rapidly to death. Pulmonary system involvement and pulmonary hypertension are the most frequent cause of death. When the patient with SSc is to be operated, the anesthetic procedure could be a serious problem. In this article, we report a combined spinal – epidural technique in a patient with progressive SSc and the anesthetic considerations that could be recommended for these patients.Case presentationA 68-year-old woman who had a history of progressive systemic sclerosis, pulmonary fibrosis, kyphoscoliosis and decreased oral apertura underwent total hip arthroplasty. This operation was performed successfully under combined spinal epidural anesthesia.ConclusionSystemic sclerosis is a complex disease that involves multiple organ systems. Every aspects of anesthetic care may be altered or hindered by the pathogenesis of disease. Although the choice of regional or general anesthesia is unclear, to choose combined spinal epidural anesthesia may be useful.

Phenol preparations are used in dermatology and plastic surgery for the treatment of acne and during chemical face peeling. At this institution, phenol peeling is used in addition to mechanical dermabrasion for the elimination of subclinical premalignant lesions of patients having xeroderma pigmentosum. As the phenol peel is performed, most surgeons concentrate on skin results, ignoring systemic complications. Local histological changes and systemic toxicity have been seen during applications. Cardiac arrhythmias and even sudden death have been reported. The high incidence of cardiac arrhythmias after topical application of phenol preparations is demonstrated. The case of an 11-year-old boy with a diagnosis of xeroderma pigmentosum who underwent mechanical dermabrasion and chemical peeling with phenol and then developed severe cardiac arrhythmias is reported. A serious systemic toxic effect on cardiac rhythm from cutaneously applied phenol occurred in this case.
