Randomized Controlled TrialEvaluation of preemptive effect of epidural S(+)-ketamine for hysterectomy: plasmatic concentrations of interleukins.
Some studies showed that ketamine inhibits the production of cytokines. The objective of this study was to evaluate the preemptive analgesic effect of epidural S(+)-ketamine in hysterectomy and plasmatic cytokines (IL-6, TNF-α and IL-10). ⋯ The epidural injection of 25mg S(+)-ketamine before incision reduced the pain intensity only 12 hours after surgical incision and did not alter concentration of cytokines.

ReviewBispectral index and other processed parameters of electroencephalogram: an update.
The processed analysis of electroencephalogram became extremely important to monitor nervous system, being used to obtain a better anesthetic adequacy. The objective was to conduct a review about each processed parameter, defining its real importance. ⋯ An adequate analysis of processed parameters of electroencephalogram may provide more intraoperative safety as well as result in a better outcome for the patient.

Randomized Controlled Trial Comparative StudyPostoperative analgesic efficacy of different volumes and masses of ropivacaine in posterior brachial plexus block.
The efficacy of posterior brachial plexus block for shoulder surgeries is demonstrated by different authors. However, there is no consensus on the ideal mass and volume of local anesthetic to be employed. The objetive of this study was to compare different volumes and masses of ropivacaine in posterior brachial plexus block in arthroscopic surgeries of the shoulder. ⋯ This study concluded that 5 mL of 1% ropivacaine promoted analgesic efficacy similar to 10 mL or 20 mL of 0.5% ropivacaine in the posterior brachial plexus block using neurostimulator.

Case ReportsIntracranial subdural hematoma: a rare complication following spinal anesthesia: case report.
Intracranial subdural hematoma is a rare complication following spinal anesthesia. The diagnosis is usually difficult because initial symptoms are the same of post-dural puncture headache. The objective was to report a case of early diagnosed subdural hematoma after spinal anesthesia performed with a fine-gauge needle and single puncture. ⋯ Headache is the most frequent complication after spinal anesthesia and it is considered of benign evolution. In many cases however, it leads to the late or absent diagnosis of potentially fatal conditions, like subdural hematoma. This case describes a rare case of an acute subdural hematoma following spinal anesthesia with fine-gauge needle in a patient without risk factors for bleeding.

ReviewSuprascapular nerve block: important procedure in clinical practice.
Shoulder pain is a frequent complaint that results in great functional disability in the affected shoulder as well as the decrease in patients' quality of life. Suprascapular nerve block is an effective therapeutic method and has been increasingly used by anesthesiologists both for regional anesthesia and postoperative analgesia of surgeries carried out in this articulation, which justifies this review, whose main purpose was to describe the applied technique and clinical indications. ⋯ Suprascapular nerve block is a safe and extremely effective procedure in shoulder pain therapy. It also has an easy reproducibility and has been very used by professionals of many medical specialties. When it is well-indicated, this method must be taken into consideration.
