Intravenous anesthesia, using sedative for the rapid loss of consciousness and analgesic for the potent and short-acting effect, has been widely done.
So this study is aimed to see if propofol-fentanyl are effective enough for extracorporeal shock wave lithotripsy(ESWL) used for outpatient and how it will effects on cardiovascular system.
Above all, 45 patients were selected randomly and their blood pressure(BP), heart rate(HR), respiratory rate(RR)and arterial oxygen saturation(SaO2) were measured shortly before giving propofol and fentanyl. Then, after giving propofol and
fentanyl, BP,
HR, RR and SaO2 were measured as the adequate depth of anesthesia. And after 5 to 10 minutes, ESWL was done. Involuntary movements and pain were checked as additional depth of anesthesia.
With the time, HR and SaO2 showed statistically significant decrease with no clnical meanings.
And there was no special treatment for involuntary movements founded in 8 patients but 13 patients suffering from pain were given additional fentanyl.
In conclusion, intravenous anesthesia with propofol and fentanyl works effectively for ESWL Therefore if during ESWL, cardiopulmonary functions are monitored carefully, intravenous anesthesia with propofol and fentanyl will be an effective and
safe
anesthesia.(Korean J Anesthesiol 1995; 29: 552∼557)
