injection on the morphine dose response was examined in both naïve rats and rats made tolerant by continuous infusion of morphine (15 μg/h i.t).
We performed bolus infusion of 40 60 mL ropivacaine 0.2% followed by continuous infusion of 4 6 mL/h of ropivacaine 0.2%.
During the entire experiment, anesthesia is maintained by continuous infusion of ketamine (15 mg/kg/h), fentanyl (20 μg/kg/h), and midazolam (0.9 mg/kg/h).
A volume baseline is established by continuous infusion of a balanced electrolyte solution (Jonosteril® PL 1000 ml, Fresenius Kabi Deutschland GmbH, Bad Homburg, Germany, 10 ml/kg/day).
After oxygenation, general anesthesia was induced by continuous infusion of remifentanil (0.5 μg/kg/min), intravenous bolus administrations of propofol (20 mg), and rocuronium (30 mg).
Before the abdominal incision was made, 6 ml of 1% lidocaine was injected epidurally, followed by continuous infusion of 0.3% ropivacaine at a rate of 4 6 ml/h to obtain abdominal muscle relaxation.
Anesthesia and neuromuscular blockade were maintained by continuous infusion of propofol (10 mg/kg/h), fentanyl (5 μg/kg/h), and vecuronium (0.3 mg/kg/h) throughout the all experiments which lasted for less than 1 h.
PTH has been shown to accelerate orthodontic tooth movement on rats, which was studied by continuous infusion of PTH (1 to 10 μg/100 g of body weight/day) implantation in the dorsocervical region, and the molars were moved 2- to 3-fold faster mesially by orthodontic coil spring [18].
Results While impairment of contractile cardiac function by continuous infusion of verapamil resulted in significant changes of cdP/dtAo and cdP/dtLV (p < 0.05), neither in normal as well as in impaired cardiac function did cdP/dtAo and cdP/dtLV present significant changes during preload modifications (p > 0.05).
Animals underwent 2 randomly-ordered experimental sequences of respiratory and metabolic acidosis, obtained by reducing the respiratory rate or by continuous infusion of lactic acid, respectively, targeting an arterial pH of 7.15 ± 0.02. the electrodialysis treatment was then started to restore baseline pH.
A bolus of 0.3 mg/kg medetomidine was followed by continuous infusion of 0.6 mg/kg/h [30].
