Input: Consider Input: Abstract: In 14 intubated, spontaneously breathing children with body weight (bw) ranging from 8.3 to 25.6 kg, the influence of midazolam 0.1 mg kg-1 i.m. (group M0.1, n = 7) and 0.2 mg kg-1 i.m. (group M0.2, n = 7) as premedication, on sedation, ventilation, ventilatory response to carbon dioxide and hormonal stress response was studied in connection with minor surgical procedures during halothane anaesthesia. The concentrations of catecholamines, ACTH and cortisol were measured immediately after induction, during undisturbed anaesthesia, during surgery and 15 min after the end of the surgical procedure. Sedation was better and plasma catecholamine concentrations during undisturbed anaesthesia were less in children receiving the larger dose of midazolam. During surgery and in recovery there were no differences in hormone concentrations. In recovery, the concentrations of all hormones were significantly greater compared with during undisturbed anaesthesia. During surgery, VE and respiratory rate were somewhat lower in group M0.2 while E' CO2 was similar. A dose dependent depression of the response to carbon dioxide was found. However, clinically, the ventilatory response to carbon dioxide after surgery was considered to be adequate in both groups.

Output: Ventilation, ventilatory carbon dioxide and hormonal response during halothane anaesthesia and surgery in children after midazolam premedication.

Input: Consider Input: Abstract: Heparin-induced thrombocytopenia with thromboembolism calls for an immediate substitution of the heparin with other potent anticoagulants, such as coumarin derivatives. The occurrence of this adverse effect in pregnancy poses an additional dilemma because the use of coumarin derivatives is not acceptable during pregnancy, while other medications may not be as effective. In a pregnant patient treated with mucous sodium heparin for deep vein thrombosis, recurrent heparin-induced thrombosis and disseminated intravascular coagulation (DIC) occurred. Replacing the heparin with a different brand of the same drug resulted in reversal of the DIC and in clinical improvement. If severe heparin-induced thrombosis occurs in a patient in whom anticoagulation with other drugs is contraindicated, substituting one brand of heparin for another could be of value.

Output: Heparin-induced thrombocytopenia and recurrent thrombosis in pregnancy. A case report.

Input: Consider Input: Abstract: Studies were designed to explore the association of lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) activities with lipoproteins in human postheparin plasma (PHP). The major peak of LPL activity after gel filtration of PHP eluted after the triglyceride-rich lipoproteins and just before the peak of low density lipoprotein (LDL) cholesterol. When PHP contained chylomicrons, an additional peak of LPL activity eluted in the void volume of the column. Most HTGL activity eluted after the LDL and preceded the elution of high density lipoprotein cholesterol. LPL activity in preheparin plasma eluted in the same position, relative to lipoproteins, as did LPL in PHP. Gel filtration of purified human milk LPL mixed with plasma or isolated LDL produced a peak of activity eluting before LDL. During gel filtration of PHP in high salt buffer (1 M NaCl) or after isolation of lipoproteins by ultracentrifugation in high salt density solutions, most of the lipase activity was not associated with lipoproteins. LPL activity was removed from PHP by elution through immunoaffinity columns containing antibodies to apolipoprotein (apo) B and apo E. Since lipoproteins in PHP have undergone prior in vivo lipolysis, LPL activity in PHP may be bound to remnants of chylomicrons and very low density lipoproteins.
Output: Association of plasma lipoproteins with postheparin lipase activities.
