ReviewGuideline-oriented perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.
Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. ⋯ Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

Comparative StudyChanges in polymorphonuclear leukocyte elastase concentrations and hemolysis parameters in patients transfused with different blood preparations, and in the blood preparations themselves.
Massive blood transfusion induces hemolysis and increases polymorphonuclear leukocyte elastase (PMNE) concentration. The purpose of this study was to compare hemolysis and PMNE concentrations in massive blood transfusions with three different preparations. ⋯ During the storage of MAP-CRC, CPD-CRC, and WB, CPD-CRC had the greatest hemolysis and WB had the highest concentration of PMNE. Patients who received massive blood transfusion of MAP-CRC had the least hemolysis and the lowest concentration of PMNE.

Comparative StudyComparison of oxygen consumption calculated by Fick's principle (using a central venous catheter) and measured by indirect calorimetry.
We investigated the clinical usefulness of the Fick method using central venous oxygen saturation ScvO2 and cardiac output (CO) measured by pulse dye densitometry (PDD) for monitoring oxygen consumption VO2. This prospective clinical study was performed in 28 mechanically ventilated postoperative patients after major abdominal surgery. VO2 was determined by two methods, i.e., the Fick method and indirect calorimetry. ⋯ VO2 values determined by the Fick method were significantly lower than those measured by indirect calorimetry (110 +/- 29 vs 148 +/- 28 ml x min(-1) x m(-2); P < 0.01). Bland and Altma analysis showed that the mean bias and precision were 33 ml x min(-1) x m(-2) and 32 ml x min(-1) x m(-2), respectively. The correlation between the two measurements of VO2 was weak (r (2) = 0.145; P = 0.0038), indicating that the Fick method using PDD and ScvO2 is not clinically acceptable for the monitoring of VO2.

Randomized Controlled TrialThe effect of heat-moisture exchanger and closed-circuit technique on airway climate during desflurane anesthesia.
We assessed whether closed-circuit anesthesia (CCA) could provide a more favorable airway climate than semi-closed anesthesia (SCA), and we also determined the beneficial effect of heat moisture exchangers (HMEs) on the preservation of airway climate during desflurane anesthesia. ⋯ CCA was much more advantageous than SCA for maintaining the patient's airway climate during the 2-h study. The beneficial effect of HME on the airway climate should be emphasized, especially in patients undergoing general anesthesia.

Case ReportsCalcineurin-inhibitor-induced pain syndrome after bone marrow transplantation.
Calcineurin-inhibitor-induced pain syndrome (CIPS), a rare complication seen in patients with organ transplants, is associated with the use of calcineurin inhibitors (CIs) such as cyclosporine (CSP) and tacrolimus (FK). Patients with this syndrome usually present with severe leg pain. This case report demonstrates the successful pain control of this pain syndrome in a 42-year-old female patient who had been given CIs (FK and CSP) as an immunosuppressive agent after a bone marrow transplant. ⋯ Due to the presence of allodynia, our patient's pain had neuropathic pain-like characteristics, unlike the pain in previously reported patients with other organ transplants. Her pain was successfully relieved by the administration of oral amytriptyline, clonazepam, oxycodone, and intravenous lidocaine, all of which ordinarily have an analgesic effect on neuropathic pain. CIPS in patients with hematopoietic stem cell transplants treated with FK may have a mechanism by which neuropathic pain may develop that is different from that in patients with other organ transplants.
