Dexamathasone added to levobupivacaine improves postoperative analgesia in ultrasound guided interscalene brachial plexus blockade for arthroscopic shoulder surgery.
The purpose of this study was to evaluate the effect of the addition of 5 mg dexamethasone to 10 ml of 0.5% levobupivacaine on postoperative analgesic effects of ultrasound guided-interscalene brachial plexus block (ISBPB) in arthroscopic shoulder surgery under general anesthesia. ⋯ We conclude that the addition of 5 mg of dexamethasone to 10 ml of 0.5% levobupivacaine in ISBPB showed improvement of postoperative analgesia for arthroscopic shoulder operation without any specific complications.

Macintosh laryngoscope vs. Pentax-AWS video laryngoscope: comparison of efficacy and cardiovascular responses to tracheal intubation in major burn patients.
Patients with major burns accompanied with airway edema need more attention for airway management. Although the Pentax-AWS has an advantage in managing endotracheal intubation more easily, its usefulness cannot be assured if it does not maintain hemodynamic stability in burn patients. The aim of this study was to compare cardiovascular responses and general efficacy of the Pentax-AWS and Macintosh laryngoscopes in burn patients. ⋯ The use of Pentax-AWS offers a reduced degree of heart rate elevation compared with the Macintosh laryngoscope and better intubation environments in major burn patients.

Relation between preoperative autonomic function and blood pressure change after tourniquet deflation during total knee replacement arthroplasty.
Tourniquets are used to provide a bloodless surgical field for extremities. Hypotension due to vasodilation and bleeding after tourniquet deflation is a common event. Hemodynamic stability is modulated by the autonomic nervous system (ANS). Heart rate variability (HRV) is a sensitive method for detecting individuals who may be at risk of hemodynamic instability during general anesthesia. The purpose of this study was to investigate ANS function to predict hypotension after tourniquet deflation. ⋯ Preoperative low BRS is associated with hypotension after tourniquet deflation, suggesting the importance of baroreflex regulation for intraoperative hemodynamic stability.

Effect of ketamine on intravenous patient-controlled analgesia using hydromorphone and ketorolac after the Nuss surgery in pediatric patients.
Nuss surgery is preferred in pectus excavatum repair because this procedure produces excellent cosmetic results and prevents postoperative distressed pulmonary function. However, the procedure causes severe pain due to thoracic expansion. This study was designed to investigate the analgesic effect of small doses of ketamine on an intravenous patient-controlled analgesia (IV-PCA) using hydromorphone and ketorolac for pain control after Nuss surgery. ⋯ A small dose of ketamine on IV-PCA reduced the total administered dose of IV-PCA with hydromorphone and ketorolac and reduced the incidence of pruritus after the Nuss procedure in pediatric patients.

The effect of dexmedetomidine on the adjuvant propofol requirement and intraoperative hemodynamics during remifentanil-based anesthesia.
The effects of dexmedetomidine on the propofol-sparing effect and intraoperative hemodynamics during remifentanil-based propofol-supplemented anesthesia have not been well investigated. ⋯ Dexmedetomidine reduced the propofol requirement for remifentanil-based anesthesia while producing more stable intraoperative hemodynamics.
