Randomized Controlled Trial Clinical TrialComparative effect of 6% hydroxyethyl starch (containing 1% dextrose) and lactated Ringer's solution for cesarean section under spinal anesthesia.
This study aimed to compare low-molecular weight hydroxyethyl starch containing 1% dextrose (HES) infusion and lactated Ringer's solution (LR) in the prevention of hypotension associated with spinal anesthesia for cesarean section. ⋯ This study did not show an advantage of HES compared with LR in the prevention of hypotension or in the reduction of ephedrine dose during cesarean section under spinal anesthesia. The anesthesia level, rather than the choice of intravenous fluid solution, might be related to the ephedrine dose.

Randomized Controlled Trial Clinical TrialComparison of heart rate changes after neostigmine-atropine administration during recovery from propofol-N2O and isoflurane-N2O anesthesia.
Propofol augments the reduction of heart rate (HR) in combination with cholinergic agents and attenuates the HR response to atropine. We examined whether propofol anesthesia was associated with an increased incidence and extent of bradycardia after neostigmine-atropine administration compared with the effects of isoflurane anesthesia. ⋯ We conclude that propofol anesthesia attenuates the initial increases in HR, enhances the subsequent decreases in HR, and increases the incidence of bradycardia after neostigmine-atropine injections compared with the effects of isoflurane anesthesia.

Randomized Controlled Trial Clinical TrialThe effect of propofol infusion on minimum alveolar concentration of sevoflurane for smooth tracheal intubation.
This study was conducted to determine the effect of propofol infusion on the minimum alveolar concentration necessary for smooth tracheal intubation (MACEI) of sevoflurane. ⋯ Propofol infusion reduced sevoflurane MACEI. This finding suggests that propofol would be an excellent adjuvant to use with sevoflurane for tracheal intubation.

Randomized Controlled Trial Clinical TrialHemodynamic stability during induction of anesthesia and tracheal intubation with propofol plus fentanyl, ketamine, and fentanyl-ketamine.
This study was conducted to investigate hemodynamic and cardiac stability during anesthesia induction and intubation, using propofol plus fentanyl, propofol plus ketamine, and propofol plus fentanyl and ketamine. ⋯ A combination of propofol plus fentanyl plus ketamine would provide greater reduction of fluctuations in hemodynamic variables associated with induction of anesthesia and tracheal intubation than combinations of propofol plus fentanyl or propofol plus ketamine.
