Pelvic fracture in multiple trauma: classification by mechanism is key to pattern of organ injury, resuscitative requirements, and outcome.

Three hundred forty-three multiple trauma patients with major pelvic ring disruption were studied and subdivided into four major groups by mechanism of injury: antero-posterior compression (APC), lateral compression (LC), vertical shear (VS), and combined mechanical injury (CMI). Acetabular fractures which did not disrupt the pelvic ring were excluded. The mode of injury was: MVA, 57.

Controlled ventilation in dental outpatients. Controlled ventilation with atracurium and alfentanil analgesia compared with halothane.

This study compares anaesthesia with controlled ventilation of the lungs with atracurium and alfentanil analgesia with halothane anaesthesia. Recovery time, the incidence of dysrhythmias and postoperative morbidity were evaluated. Anaesthesia with controlled ventilation was found to reduce significantly the incidence of cardiac dysrhythmias during dental surgery, and to produce a significantly more rapid recovery than halothane anaesthesia.

Metabolic rate and thyroid status in rats fed diets of different protein-energy value: the importance of free T3.

Oxygen consumption and thyroid hormone status have been investigated in relation to dietary protein and energy intake in young growing rats fed a control diet of 18% protein as well as diets containing 9 and 4.5% protein fed ad libitum and an 18% protein diet fed at a restricted intake for up to 14 days. Measurements of growth rate, food intake and oxygen consumption indicated that the rats fed a 4.

Muscle protein synthesis in the streptozotocin-diabetic rat. A possible role for corticosterone in the insensitivity to insulin infusion in vivo.

The effect of insulin infusion in vivo on muscle protein synthesis was investigated in rats. In 10-days-streptozotocin-diabetic rats infused in vivo with amino acids and glucose, the rate of protein synthesis per unit of RNA (RNA activity) was markedly decreased. Pre-treatment with large doses of insulin at 17 and 1 h before the infusion fully restored RNA activity to normal.

Developmental defects of the lungs.

Poor lung development was first noted on scintigraphy using 99mTc-phytate in 32 children. They had all been referred for a hepatosplenic scan but the initial circulatory phase of the radiopharmaceutical was also recorded as a routine procedure. In 3 patients it revealed aplasia of an entire lung; bilateral pulmonary hypoplasia was observed in 14 of 16 patients with diaphragmatic herniae.
