Epidural abscess after patient-controlled epidural analgesia. Case report.
Epidural analgesia is often used to control postoperative pain or to manage chronic pain in oncologic patients. However, it is not free from complications. This case reports a young healthy female patient submitted to epidural analgesia in patient-controlled infusion pump, which developed epidural abscess requiring surgical decompression. ⋯ Epidural analgesia often used to control postoperative or chronic pain, although very effective, is not free from severe, although rare complications, such as epidural abscess.

Inhaled gases humidification and heating during artificial ventilation with low flow and minimal fresh gases flow.
Inhaled gas humidification and heating are necessary in patients under tracheal intubation or tracheostomy to prevent damage to respiratory system resulting from the contact of cold and dry gas with the airways. This study aimed at evaluating the effect of respiratory circle systems with carbon dioxide absorbers from Dräger's Cicero anesthesia machine (Germany) as to inhaled gases heating and humidification ability using low fresh gases flow (1 L min(-1)) or minimum flow (0.5 L min(-1)). ⋯ There have been no significant differences in inhaled gas humidity and temperature with fresh gases low flow or minimum flow.

In has been shown in non-obstetric patients, that a fast acute fluid preload immediately after spinal anesthesia was more effective than a slow preload before regional block to decrease the incidence and severity of arterial hypotension after spinal anesthesia. This study aimed at comparing the incidence of arterial hypotension and vasopressants consumption in parturients submitted to C-section under spinal anesthesia with different fluid preload regimens. ⋯ Acute preload before or after spinal anesthesia performance, in a slow or fast rate, does not change vasopressants consumption, the incidence of maternal arterial hypotension, nausea and vomiting, as well as fetal wellbeing.

Remifentanil is the newest opioid for anesthetic procedures. This study aimed at reviewing the literature, with emphasis on information of clinical interest published from January 2000 to December 2002. ⋯ Remifentanil is currently the best opioid for continuous intravenous infusion and may improve anesthesiologist's efficiency provided usage recommendations are followed.

Influence of stimulation frequency on rocuronium and pancuronium-induced neuromuscular block onset. Acceleromyography evaluation.
Factors associated to patients and neuromuscular blockers (NMB), as well as others inherent to neuromuscular function monitoring, may affect neuromuscular block onset. This study aimed at the influence of two different stimulation frequencies on rocuronium and pancuronium-induced neuromuscular block. ⋯ Rocuronium and pancuronium-induced neuromuscular block onset and time required for complete adductor pollicis muscle neuromuscular block are shorter when higher stimulation frequencies are applied.
