Randomized Controlled Trial Comparative Study
Assessment of the effect of ketamine in combination with remifentanil on postoperative pain.
The combination of ketamine and remifentanil seems to be associated with better analgesia and duration. The aim of this study was to evaluate whether a ketamine- remifentanil combination promotes improved postoperative analgesia. ⋯ The combination of ketamine (5 mcg.kg(-1).min(-1)) and remifentanil (0.4 mcg.kg(-1).min(-1)) for cholecystectomy did not alter the severity of postoperative pain, time to first analgesic supplementation or dose of morphine in 24 hours.

The practice of anesthesiology is not without risks to the anesthesiologist. The operating room (OR), in which anesthesiologists spend most of their time, is regarded as an unhealthy workplace due to the potential risks it offers. In this review, we propose an analysis of the occupational hazards that anesthesiologists are exposed in their daily practice. ⋯ Control of occupational hazards to which anesthesiologists are exposed daily is necessary in order to develop an appropriate workplace and minimize risks to the good practice of anesthesiology. This contributes to decrease absenteeism, improve patients' care and quality of life of anesthesiologists.

Randomized Controlled Trial
The effect of levobupivacaine and bupivacaine on QT, corrected QT (Qtc), and P wave dispersions in cesarean section.
In our study we aimed to investigate the effect of bupivacaine and levobupivacaine on QT, corrected QT (QTc), and P wave dispersion durations during spinal anesthesia in cesarean section. ⋯ Bupivacaine and levobupivacaine may be preferred in spinal anesthesia in pregnant patients who have extended Pwd and QTcd preoperatively.

Preoperative tests aim to reduce morbidity and mortality of surgical patients, cost of perioperative care, and preoperative anxiety. Clinical evaluation allows defining the need for additional tests and strategies to reduce the surgical-anesthetic risk. The aim of this study was to evaluate the benefit of routine preoperative testing of low-risk patients undergoing minor and medium surgical procedures. ⋯ We found that preoperative additional tests are excessively ordered, even for young patients with low surgical risk, with little or no interference in perioperative management. Laboratory tests, besides generating high and unnecessary costs, are not good standardized screening instruments for diseases.

Randomized Controlled Trial
Ropivacaine, articaine or combination of ropivacaine and articaine for epidural anesthesia in cesarean section: a randomized, prospective, double-blinded study.
Initiation of epidural anesthesia with long-lasting local anesthetics consumes a significant amount of time, which could be problematic in busy obstetric anesthesia suites. We have hypothesized that a combination of articaine and ropivacaine provides faster onset and even an early recovery of sensory-motor block characteristics. ⋯ A combination of 2% articaine and 0.75% ropivacaine for epidural anesthesia in a cesarean section should be preferred over epidural 0.75% ropivacaine alone.
