Comparison between Naropin and Bupivacaine Used in Lower Level Epidural Obstruction
Abstract: Objective: To compare 0.5% Naropin with 0.5% Bupivacaine in clinical effect and safe for epidural anesthesia. Method: 40 cases of patients (ASA I II grades) who are operated on lower abdomen under epidural anesthesia are divided into two groups; Naropin group: 0.5% Naropin (n = 20 cases); Bupivacaine group: 0.5% Bupivacaine (n = 20 cases). Taking L2~3 lines epidural puncture to be initially injected for Naropine or Bupivacaine 8~10 ml, gross dosage doesn’t exceed 20 ml. To observe two groups of patients who use gross medicine dosage, feeling obstruction scope, effect of initial taking medicine and side effect. Result: The difference between two groups using gross medicine dosage, feeling obstruction scope, effect of initial taking medicine is not clear; The Naropin group stopping pain time, muscle relaxing effect and feeling movement obstruction separation are relatively stronger than that of Bupivacaine group; The low blood pressure rate for Naropin is higher than that of Bupivacaine group. Conclusion: The 0.5% Naropin is better than 0.5% Bupivacaine in low level of epidural anesthesia. The Naropin group stopping pain time, muscle relaxing effect and feeling movement obstruction separation are relatively stronger than that of Bupivacaine group.
