Effortil is commonly used in this country as a vasopressor, replacing ephedrine. Various sbustances(i. e. ephedrine, neosynephrine, methedrin and epinephrine) have been added to spinal anesthetic agents in an attempt to prolong their action. We have used premixed 5% lidocaine with 5% dextrose solution as a main agent for spinal anesthesia for the past 6 years, and epinephrine has been used to prolong the spinal anesthesia. In this study, we have attempted to assess the possibility of the clinical use of Effortil in comparison with epinephrine for prologing the anesthetic effect of a spinal anesthetic agent. As a control group, 404 patients received premixed 5% lidocaine solution. In the 2nd group, 398 patients received 0. 2 mg of epinephrine added to the lidocaine solution. In the 3rd group, 337 patients received 3.0mg of Effortil added to the lidoeaine solution. The average duration of anesthetic effect was 97 minutes in the control group with lidocaine, 151 minutes in the 2nd group with epinephrine added to the lidocaine solution, and 113 minutes in the last group with Effortil added to the lidocaine solution. As a result of this study, we came to the conclusion that the Effortil may have a slight prolonging effect. However its effect is questionable as to its reliability for clinical use. Epinephrine is far better than Effortil and is more reliable and predictable for clinical use, as previously reported by other workers. |
