Induction of anesthesia with propofol in urological outpatient surgery.
Propofol (Diprivan) in a new formulation, a short-acting intravenous anesthetic, was used as an induction agent for short urological procedures. Forty unpremedicated patients were treated with either propofol or thiopental in a randomized study. The onset of anesthesia and duration of apneic period were prolonged and the decrease in systolic blood pressure was more profound in the propofol group. Heart rate was less stable and recovery time was longer in the thiopental group. Other parameters, such as quality of anesthesia, acceptability of the drug or rate of side effects, were similar in both groups. These results suggest that propofol in a new formulation is a suitable agent for short urological procedures in outpatient surgery.

The effect of alfentanil on experimental myocardial infarction size: a comparison with fentanyl and halothane.
We compared the action of alfentanil on experimental myocardial infarction size with two widely used anesthetic drugs: fentanyl and halothane. Myocardial infarction size, measured by histological techniques, was identical for the three drugs investigated. Our results demonstrate that the action of alfentanil on factors governing myocardial oxygen supply and demand in the rat with coronary artery ligation is no different from the action of fentanyl or halothane.

Embolization of detached fragments of intravenous plastic catheter.
Three cases of embolization by detached fragments of "Intracath" intravenous catheters are described. In two, successful surgical removal was performed, whilst in the third, due to the poor general condition of the patient, no attempt at removal was made and after long-term observation, there were no untoward side effects.
