The analgesic effect of the ultrasound-guided transverse abdominis plane block after laparoscopic cholecystectomy.
Several methods are performed to control the pain after a laparoscopic cholecystectomy. Recently, the transverse abdominis plane block has been proposed to compensate for the problems developed by preexisting methods. This study was designed to evaluate the effect of the ultrasound-guided transverse abdominis plane block (US-TAP block) and compare efficacy according to the concentration of local analgesics in patients undergoing laparoscopic cholecystectomy. ⋯ The US-TAP block with 0.25% or 0.5% levobupivacaine 30 ml (15 ml on each side) significantly reduced postoperative pain in patients undergoing laparoscopic cholecystectomy.

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.

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.
