Mandibular nerve block allows surgery to be performed on the mandible. However, pain in the postoperative period needs to be treated with opioids or non-steroidal anti-inflammatory agents which have undesirable side effects. We examine the feasibility of continuous mandibular nerve block with 0.25% bupivacaine top-ups using a catheter for intraoperative and postoperative pain relief in two patients with a fracture of the mandible. ⋯ Continuous mandibular nerve block with 2-4 mL 0.25% bupivacaine top-ups injected twice a day through a catheter provides excellent pain relief in patients with a fracture of the mandible. This method may have implications for the management of pain of other etiology in the mandibular region.

Case Reports
The anesthetic management of ventricular septal defect (VSD) repair in a child with mitochondrial cytopathy.
To present the anesthetic management for the correction of a ventricular septal defect (VSD) in a patient with multiple acyl CoA dehydrogenase deficiency (glutaric aciduria type II; GAII). A review of the literature about anesthetic management of patients with mitochondrial diseases undergoing cardiopulmonary bypass (CPB) is also included. ⋯ The anesthetic management of patients with any mitochondrial disease requires normoglycemia, normothermia and the avoidance of metabolic stress in order to preserve energy production by the diseased mitochondria.

Case Reports
Complete separation of the tube from the mask during removal of a disposable laryngeal mask airway.
To describe a complication of the disposable laryngeal mask airway (LMA). ⋯ Although the use of the LMA is associated with rare and minimal complications, each airway should be carefully inspected before its use for loss of integrity resulting from sterilization or for defects in manufacturing.

Randomized Controlled Trial Comparative Study Clinical Trial
Dopamine may preserve the myocardial oxygen balance better than dobutamine when administered with milrinone.
To compare the hemodynamic effects of dopamine with those of dobutamine when administered with milrinone in patients undergoing non-cardiac surgery. ⋯ Dopamine and dobutamine administered with milrinone induce different hemodynamic changes: dopamine increases MAP without affecting HR, whereas dobutamine increases HR. Our data suggest that the myocardial oxygen balance might be better preserved with dopamine than with dobutamine when administered with milrinone.

Clinical Trial
Systolic blood pressure, not BIS, is associated with movement during laryngoscopy and intubation.
To compare bispectral index (BIS) values to hemodynamic variations, in order to evaluate adequacy of anesthesia during orotracheal intubation with muscle relaxants. ⋯ Systolic pressure elevations were associated with inadequate anesthesia as evaluated by the "isolated forearm" technique, during laryngoscopy/intubation. BIS values were not different between groups, suggesting that systolic blood pressure may be a better predictor of inadequate anesthesia under the circumstances described.
