It is common clinical practice to use dopamine to manage the reduction in blood pressure accompanying epidural blockade. As propofol is a high-clearance drug, propofol concentrations can be influenced by cardiac output (CO). The purpose of the present study was to investigate the effects of dopamine infusions on propofol concentrations administered by a target-controlled infusion system during epidural block under general anesthesia. ⋯ Propofol concentrations decrease with an increase in CO, suggesting the possibility of inadequate anesthetic depth following catecholamine infusion during propofol anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Prevention of PONV by acustimulation with capsicum plaster is comparable to ondansetron after middle ear surgery.
To compare the efficacy of stimulation of P6 acupoint with capsicum plaster in comparison with iv ondansetron for the prevention of postoperative nausea and vomiting (PONV). ⋯ Stimulation of the P6 acupoint with capsicum plaster is an effective method for prevention of PONV after middle ear surgery and its efficacy is comparable to ondansetron for the first six hours after surgery.

To investigate the reliability of cardiac output assessed by arterial pressure waveform (PulseCO) in comparison with bolus thermodilution measurements in patients undergoing off-pump coronary artery bypass grafting (OPCAB). ⋯ Cardiac output by PulseCO is not interchangeable with cardiac output measured by thermodilution in patients undergoing OPCAB.

Delayed recovery of vecuronium neuromuscular block in diabetic patients during sevoflurane anesthesia.
To study recovery from vecuronium-induced neuromuscular block in diabetic patients during total iv or sevoflurane anesthesia. ⋯ In diabetic patients receiving vecuronium, recovery of T1/control and TOF ratio are delayed during sevoflurane anesthesia, but not in association with total iv anesthesia.
