Background: Total Intravenous Anesthesia (TIVA) compared to general anesthesia has some pits and falls. Many drugs have been employed for this anesthesia. Propofol is accounted as the last advent anesthetic drug. It belongs to alkyl phenol families and has been accounted one of the best choices for the continuous infusion. Invention of midazolam as the first water soluble benzodiazepine was also an important event in anesthesia and it can be used as continuous infusion for the anesthesia. Materials and Methods: In this randomized controlled clinical trial, alfentanyl plus propofol or midazolam were used for TIVA anesthesia in 60 female patients undergoing Dilatation and Curettage (D&C) in Dr.Shariati hospital in March 2002 till March 2003. They were allocated reandomly in two group of alfentanyl plus propofol (propofol group) or alfentanyl plus midazolam (midazolam group) Results: There was no significant difference in mean of age between propofol group and midazolam group (P>0.05), also There was no significant difference in preanesthesia condition such as blood pressure and heart rate between propofol group and midazolam group (p>0.05). After induction of anesthesia there was a gross blood pressure decrease in both group that it was greater in midazolam group (85 mmHg versus 73 mmHg, P<0.05 ); following this, there was an increase in heart rate in both groups that it was modest in propofol group (98 Beat/Sec versus 118 Beat/Sec, P<0.05). There was no significant difference in mean infused alfentanyl (P>0.05) also there was just one naloxane injection in midazolam group that have no significant difference between groups (P>0.05). Recovery room stay was significantly lower in propofol group (25 minutes versus 39 minutes, P<0.05). Conclusion: The results of this study was similar to Vuyk et.al.In their study there was a significant lower recovery time estimated by psychomotor reflexes and there was significant lower drowsiness, place and time orientation time compared to midazolam group. Finally according to the results of this study it can be resulted that TIVA with propofol is more suitable than midazolam and it can lower hospitalization time and cost. In future studies using other narcotics and other narcotics-anesthetic compounds with various dose can be mentioned. |
