Review Case Reports[Epidural anesthesia and analgesia in the perioperative treatment of a patient with Kartagener syndrome].
Kartagener's syndrome is an inherited disease characterized by a triad of symptoms--bronchiectasis, situs inversus and sinusitis--and is classified as an immotile cilia syndrome. Patients may experience specific airway problems when undergoing anesthesia for surgical procedures. We report the case of a woman with Kartagener's syndrome who underwent surgery under epidural anesthesia with postoperative epidural analgesia, both techniques proving successful.

A potential space between the dura mater and the arachnoides is thought to exist, occupied by a serous fluid and called the subdural space. Recent studies may change this classical concept, however. The dura-arachnoid complex from the epidural to the arachnoid space is formed by morphologically distinct layers: the dura mater, the subdural compartment and the arachnoid mater, which are made up of different cell types. ⋯ The zone of least resistance in the dura-arachnoid complex was the subdural compartment, which could be torn mainly along intercellular spaces, though cell rupture was also observed, affecting the cytoplasmic membranes of adjacent cells. The subdural space is opened by tearing the subdural compartment between neurothelial cells alongside the collagen fibers of the dura mater. Such a tear can be caused mechanically by injecting air or contrast media, which exert pressure on a laminar structure that tends to separate because it is weaker than neighboring ones.

Review[A new hydroxyethyl starch for volume replacement: Elohes 6%].
Various consensus groups convened in recent years to discuss plasma volume expansion solutions have suggested limiting the use of human albumin because of its high cost and have favored synthetic crystalloids or colloids for most clinical settings. Dextrans are colloids that are not widely used in most Europeans countries. Gelatins, in spite of the fact that unlimited amounts can be used, produce only moderate volume expansion and can trigger allergic reactions. ⋯ If the recommended daily dose of this HES is respected, however, coagulation disorders are minimal. The effect of HES on kidney function is at present a subject of controversy. Thus, thanks to its prolonged effect on volume and few side effects, medium molecular weight HES colloids are the ones most often recommended for use in anesthesia and postoperative intensive care.

Review[Resuscitation of the burned child in critical condition].
Recent advances in surgical techniques, control of infection and nutritional support have dramatically increased the survival rates of burned children. The characteristics of severely burned pediatric patients dictate that management be different from that required for adults in the intensive care unit. The formulas for fluid replacement should be based on body surface rather than weight in children and adjusted for degree of stress and age, with appropriate monitoring and treatment of hypothermia, pain and associated psychological disorders. Early assessment and treatment of airway obstruction and gas and smoke inhalation syndromes with high FiO2 is necessary; prophylactic endotracheal intubation may be required.

Cisatracurium is one of ten isomers that form the racemic mix of atracurium (51W89 or 1 R-cis, 1'R-cis atracurium). It is three times more potent than atracurium itself and hemodynamically stable thanks to its scarce release of histamine. Cisatracurium is hydrolyzed mainly by the pathway of Hofmann (77%) and to a lesser degree it is metabolized by organ-dependent modes (mainly by the kidney (16%)). ⋯ Cisatracurium has proven useful in intensive care because of its hemodynamic stability, which is comparable to that of steroid derivatives but with faster recovery from blockade once administration is discontinued. Its metabolism predominantly through Hofmann's pathway, with less laudanosine formation than is produced by atracurium, is also appreciated. Cisatracurium is described as the nondepolarizing muscle relaxant of choice for medium-to-long-term surgery on hemodynamically unstable patients or those with kidney or liver disease, and for neuromuscular blockade in intensive care.
