Continuous non-invasive monitoring of energy expenditure, oxygen consumption and alveolar ventilation during controlled ventilation: validation in an oxygen consuming lung model.
We have developed a combined indirect calorimetric and breath-by-breath capnographic device (GEM) for respiratory monitoring: oxygen consumption (VO2), carbon dioxide excretion (VCO2), respiratory quotient (RQ), energy expenditure (EE), alveolar ventilation (VA) and dead space/total ventilation (VD/VT). ⋯ The overall performance of the device is satisfactory and well comparable with any equipment tested. It allows near-continuous non-invasive monitoring of EE, VO2, VCO2, VA, VD/VT in ventilated, critically ill patients, providing a rationale for ventilator settings and nutritional support.

Randomized Controlled Trial Clinical TrialPostoperative pain relief by topical lidocaine in the surgical wound of hysterectomized patients.
To improve postoperative analgesia, local anesthetics have been administered perioperatively as infiltration or as aerosol in the surgical area. A previous study showed good analgesic effects by topical lidocaine in the wound in minor extraabdominal surgery (herniorraphy), while the same treatment in minor lower laparothomies did not improve postoperative analgesia. The present study investigated the effect of topical wound anesthesia using lidocaine aerosol on postoperative pain following major lower abdominal surgery. ⋯ A single dose of lidocaine aerosol topically administered in the surgical wound of hysterectomy patients improved analgesia during the first postoperative day with minimal risk of side effects.

Results of in vitro contracture testing of both parents of malignant hyperthermia susceptible probands.
Malignant Hyperthermia (MH) is regarded as a dominantly inherited condition. Therefore, most investigators do not test the second parent if the first parent is found to be MH susceptible (MHS). The purpose of this study was to validate this policy. ⋯ We conclude that both parents should be tested whenever possible. For genetic research it is important that labelling any parent "presumed normal" may give misleading results.

Case ReportsTransfusion-related acute lung injury (TRALI) after fresh frozen plasma in a patient with coagulopathy.
Transfusion-related acute long injury (TRALI) is due to specific antigen-antibody reaction involving the donor's leucocyte or granulocyte antibodies towards the recipient's antigens. Aggregation in small pulmonary vessels occurs, leading to derangement of permeability. ⋯ When TRALI is suspected the donor blood has to be tested against the recipient. Ventilatory support of the patient is continued until adequate oxygenation is reached.

Randomized Controlled Trial Comparative Study Clinical TrialNo additional analgesic effect of intra-articular morphine or bupivacaine compared with placebo after elective knee arthroscopy.
Intra-articular pain prophylaxis is a controversial measure, adding costs although the benefits are still disputed. We wanted to evaluate the effects of intra-articular opioid or local anaesthesia or a combination of the two on postoperative analgesia and analgesic consumption after elective knee arthroscopy. ⋯ Intra-articular administration of morphine or bupivacaine is not indicated after elective knee-arthroscopy in patients with minor pre-operative pain and a small surgical trauma.
