[Changes in the pain produced by the peripheral venous injection of propofol when it is combined with lidocaine or fentanyl]. / Modificación del dolor producido con la inyección venosa periférica de Propofol al combinarlo con Lidocaína o Fentanyl.

The author studied the use of intravenous Propofol for the relief of pain. He demonstrated that Propofol and 10 mg of Lidocaine intravenously decreased moderate or severe pain from 31.6% to 9% and that increasing the dose of Lidocaine did not significantly decrease the pain further. Fentanyl did not produce a statistically significant further diminution of the pain from the level of relief obtained with Propofol.
