Input: Consider Input: Abstract: Skilled forelimb use was studied in rats with unilateral lesions of the sensorimotor cortex, the caudate-putamen, or the dopaminergic nigrostriatal bundle, in a task involving reaching for food. Limb preference and efficiency were evaluated, as well as the relationship between limb use, spontaneous, and methamphetamine-induced rotation bias, both preoperatively and postoperatively. To induce use of the nonpreferred limb, a bracelet, which prevented reaching but not other movements, was attached to the forearm of the preferred forelimb. Whereas small cortical lesions of the forepaw area of the sensorimotor cortex mildly influenced limb preference and use, larger lesions changed preference. Furthermore, medium-sized sensorimotor cortex lesions impaired contralateral limb use, although surprising recovery occurred on the forced tests with the bracelet. Large cortical lesions abolished effective reaching even on the forced tests. Impairments similar to those following sensorimotor cortex lesions were also obtained following small and large caudate-putamen lesions. By contrast, unilateral dopamine depletions not only blocked use of the limb contralateral to the depletion but also impaired use of the ipsilateral limb. There was recovery in use of the ipsilateral forelimb but not the contralateral forelimb. Correlational analysis showed a weak relation between methamphetamine-induced rotation and limb preference preoperatively but no significant relation between these two variables postoperatively. The similarity in the deficits following sensorimotor cortex lesions and basal ganglia lesions suggests that skilled forelimb use depends upon a shared neural organization within the two systems.

Input: Consider Input: Abstract: Mechanical ventilation was able to induce a decrease in cardiac output and regional blood flow, especially hepatic flow. Thus, hepatic elimination of drugs with a high hepatic-extraction ratio, which was linked to alteration in hepatic blood flow, could be reduced during mechanical ventilation. The aim of this work was to determine the effect of mechanical ventilation on pharmacokinetic parameters of lidocaine, which is a well-known nonrestrictive elimination drug at the hepatic level. Five patients (mean age, 58 years) with normal hepatic function and quite similar gasometric parameters before and after weaning from mechanical ventilation were studied. With a washout period of 48 hours between mechanical ventilation and spontaneous ventilation, each patient was submitted to the following protocol: lidocaine in a bolus (1.5 mg/kg intravenously), followed by infusion (1.0 to 1.7 mg/min for 120 minutes). The results were that the peak plasma concentration after the bolus during mechanical ventilation was 3.22 +/- 0.37 mg/L (mean +/- SE) vs 2.40 +/- 0.35 mg/L during spontaneous ventilation (p less than 0.02). Steady-state plasma concentration during mechanical ventilation was 2.10 +/- 0.20 mg/L vs 1.64 +/- 0.16 mg/L during spontaneous ventilation (p less than 0.01). Total clearance was 604.2 +/- 87.0 ml/min during mechanical ventilation vs 775.0 +/- 112.1 ml/min during spontaneous ventilation (p less than 0.01). Elimination half-life was 245.2 +/- 50.6 minutes during mechanical ventilation vs 160.0 +/- 40.6 minutes during spontaneous ventilation (p less than 0.05). Distribution volume was 188.6 +/- 50.2 L during mechanical ventilation and 183.0 +/- 50.8 L during spontaneous ventilation (not significant). These preliminary data clearly demonstrated a decrease in lidocaine elimination in patients submitted to mechanical ventilation, but the magnitude of dosage adjustment of such a highly hepatic-extracted drug in patients submitted to mechanical ventilation remains to be investigated.

Input: Consider Input: Abstract: To achieve adequate arterial BP, adequate capillary filling time, and adequate peripheral pulses, hypotensive newborn infants often require higher doses of dopamine that reportedly reduce urine output in adults. Whether these larger doses of dopamine also reduce urine output in newborns is not known. Therefore, we determined the effects of administering high-dose dopamine (more than 20 micrograms/kg X min) on the urine output of 15 newborn infants. Five infants were studied prospectively and ten retrospectively. In the prospective study, urine output was determined as the dose of dopamine was increased; in the retrospective study, urine output was determined as the infants were being weaned from high doses of dopamine. Both data sets demonstrate that administering high-dosage dopamine does not reduce the urine output of sick newborn infants. Therefore, we conclude that doses of dopamine previously reported to decrease urine output in adults do not do so in sick newborn infants. Consequently, when necessary, high doses of dopamine may be used in sick newborn infants to achieve cardiovascular stability without reducing urine output.
