Sedation with sufentanil and clonidine in patients undergoing heart catheterization.

Background: Sedation for heart catheterization has been a cause for concern. Benzodiazepines, alpha-2 adrenergic agonists and opioids are used for this purpose. However, each drug has advantages and disadvantages.

[Temporary lingual nerve dysfunction following the use of the laryngeal mask airway: report].

Background And Objectives: The laryngeal mask has been frequently used in Anesthesiology. Although the rate of complications with this technique is smaller than that of the endotracheal tube, it is not devoid of risks, especially in cases of difficult airways. The objective of this study was to report a case of unilateral lingual nerve damage after the use of the laryngeal mask airway.

[Psoas muscle abscess after epidural analgesia: case report.].

Background And Objectives: Psoas muscle abscess is a rare complication of epidural analgesia. The adequate approach to this complication is fundamental for a good resolution. The objective of this report was to discuss the diagnosis and treatment of psoas muscle abscess.

Pain: current aspects on peripheral and central sensitization.

Background And Objectives: Current research has focused on the biochemical and structural plasticity of the nervous system secondary to tissue injury. The mechanisms involved in the transition from acute to chronic pain are complex and involve the interaction of receptor systems and the flow of intracellular ions, second messenger systems, and new synaptic connections. The aim of this article was to discuss the new mechanisms concerning peripheral and central sensitization.

[Intraventricular pneumocephalus after accidental perforation of the dura mater: case report.].

Background And Objectives: The loss of resistance to air to identify the epidural space is widely used. However, the accidental perforation of the dura mater is one of the possible complications of this procedure, with an estimated incidence between 1% and 2%. The objective of this report was to describe the case of a patient with intraventricular pneumocephalus after the accidental perforation of the dura mater using the loss of resistance with air technique.

[Intrathecal drugs for chronic pain control.].

Background And Objectives: Chronic pain is a challenge for modern medicine. New methods and drugs have been proposed to control pain. Intrathecal administration is a feasible and safe option, but still requires further investigations.
