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 StudyControl of pain through epidural block and incidence of cardiac dysrhythmias in postoperative period of thoracic and major abdominal surgical procedures: a comparative study.
Upper abdomen and thorax surgeries cause intense pain. Some of postoperative pain main complications are cardiocirculatory complications. The objective of this study was to test the hypothesis that postoperative analgesia with employment of local anesthetics plus spinal opioids may reduce the incidence of cardiovascular complications in postoperative period of patients in these conditions, comparing with classical methods of postoperative analgesia, opioids and NSAIDs, administered upon patient's demand. ⋯ The best quality of analgesia in postoperative period, carried out in Group A, reduced the incidence of cardiovascular complications.

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.

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.
