Randomized Controlled Trial Comparative Study
Comparison of lornoxicam and fentanyl when added to lidocaine in intravenous regional anesthesia.
In this study, our goal was to compare intraoperative and postoperative analgesic effects of lornoxicam and fentanyl when added to lidocaine Intravenous Regional Anesthesia (IVRA) in a group of outpatients who underwent hand surgery. ⋯ Addition of fentanyl to lidocaine IVRA seems to be superior to lidocaine IVRA and lornoxicam added to lidocaine IVRA groups in decreasing tourniquet pain at the expense of increasing side effects. However, lornoxicam did not increase side effects while providing intraoperative and postoperative analgesia. Therefore, lornoxicam could be more appropriate for clinical use.

Randomized Controlled Trial Comparative Study
Comparative study related to cardiovascular safety between bupivacaine (S75-R25) and ropivacaine in brachial plexus block.
Bupivacaine is a fi rst choice for regional anesthesia considering its effectiveness, long duration and less motor blockade. Bupivacaine (S75-R25) is a mixture of optical isomers containing 75% levobupivacaine (S-) and 25% dextrobupivacaine (R+) created by a Brazilian pharmaceutical company. This investigation compared cardiac safety and efficacy of bupivacaine S75-R25 with vasoconstrictor and ropivacaine for brachial plexus blockade. ⋯ This study showed similar efficacy between bupivacaine S75-R25 for brachial plexus blockade and ropivacaine, with similar incidences of supraventricular arrhythmias.

Observational Study
Postoperative nausea and vomiting: validation of the portuguese version of the postoperative nausea and vomiting intensity score.
The Postoperative Nausea and Vomiting (PONV) Intensity Scale was developed to define clinically important PONV. The aim of this study was to translate, retranslate and validate the PONV Intensity Scale for use in Portuguese Post Anesthetic Care Unit (PACU) settings. ⋯ The PONV Intensity Scale appears to be an accurate and reliable assessment and monitoring instrument for PONV in the PACU settings.

The anesthesiologist must be aware of the causes, diagnosis and treatment of venous air embolism and adopt the practice patterns to prevent its occurrence. Although venous air embolism is a known complication of cesarean section, we describe an unusual inattention that causes iatrogenic near fatal venous air embolism during a cesarean section under spinal anesthesia. One of the reasons for using self-collapsible intravenous (IV) infusion bags instead of conventional glass or plastic bottles is to take precaution against air embolism. ⋯ Fluid bags without self-sealing outlets pose a risk for air embolism if the closed system is broken down, while the flexibility of the bag limits the amount of air entry. PVC-based bags, which have more flexibility, have significantly less risk of air entry when IV administration set is disconnected from the outlet. Using a pressure bag for rapid infusion can be dangerous without checking and emptying all air from the IV bag.

Case Reports
Anesthesia for cesarean section in a patient with Guillain-Barre syndrome: case report.
Guillain-Barre syndrome during pregnancy is considered a rare neurological complication, and there is no consensus in literature for anesthetic management for cesarean section in such patients. The objective of this paper is to report the case of a pregnant woman with Guillain-Barre syndrome undergoing cesarean section. ⋯ The anesthetic technique for pregnant women with Guillain-Barre syndrome requiring cesarean section remains at the discretion of the anesthesiologist, who should be guided by the clinical conditions and comorbidities of each patient.
