Anaphylaxis with angioedema by rocuronium during induction of general anesthesia -A case report-.
Perioperative anaphylaxis is characterized by severe respiratory and cardiovascular manifestations. Correct management of anaphylaxis during anaesthesia requires a multidisciplinary approach with prompt recognition and treatment of the acute event by the attending anesthesiologist. A 34-year-old woman was scheduled to undergo endo venous laser therapy of varicose veins. ⋯ The patient received ephedrine and hydrocortisone with hydration. After achieving stable vital signs and symptom relief, surgery was performed without complications. A postoperative skin dermal test performed to identify the agent responsible revealed a positive skin test for rocuronium.

Retrospective analysis of low-dose methadone and QTc prolongation in chronic pain patients.
Methadone is a synthetic opioid that is widely used for the treatment of chronic pain. The association between methadone treatment and QT interval prolongation or which can lead to torsades de pointes has been confirmed with larger studies on high dose methadone. The aim of this study was to determine the effect of methadone on the QTc interval in patients, whether the daily dose of methadone should be lower than what has been previously investigated. ⋯ This study has shown that methadone use is associated with longer QTc intervals, even among patients with daily doses of less than 80 mg. In this study, no correlation was found between QTc duration and methadone dose, serum levels or duration of use. However, the magnitude of the QTc interval was associated with female gender and the use of antidepressants.

The change of T-wave on electrocardiogram after epinephrine test dose in spinal anesthetized adults.
This study evaluated the efficacy of a T-wave change after the IV administration of low dose epinephrine containing the test dose during spinal anesthesia. ⋯ These results suggest that a change in the T-wave amplitude is useful for detecting the unintentional IV administration of low dose epinephrine during CSEA.

Effects of preoxygenation with the three minutes tidal volume breathing technique in the elderly.
Preoxygenation with tidal volume breathing for 3 min is commonly used technique. An end tidal expiratory oxygen concentration greater than 90% is considerd to be adequate for preoxygenation. The aim of this study was to check the effects of preoxygenation on elderly patients through the comparison with young patients during the 3 min tidal volume breathing technique. ⋯ End tidal oxygen concentration did not reach 90% in 180 sec in the elderly group during preoxygenation with the 3 min tidal volume breathing technique.

Comparison of the effects of acetaminophen to ketorolac when added to lidocaine for intravenous regional anesthesia.
This study was done to evaluate the effect on pain relief when acetaminophen was added to lidocaine for intravenous regional anesthesia (IVRA). ⋯ The addition of acetaminophen to lidocaine for IVRA shortens the onset time of sensory block and delays tourniquet pain onset time, but not with ketorolac. Both acetaminophen and ketorolac reduce postoperative pain and analgesic consumption.
