Abstract:
Objective To determine the optimum dose of Oxycodone for anesthesia induction in patients undergoing laparoscopic cholecystectomy. Methods Ninety patients, ASA Ⅰ or Ⅱ , scheduled for elective LC, were randomly divided into 3 groups using random number table (O 1~O 3 groups, n = 30 each). Anesthesia was induced with iv Propofol 1.00~2.00 mg/kg, Oxycodone 0.20 mg/kg, 0.3 mg/kg and 0.4 mg/kg (O 1~O 3 groups, respectively), and Vecuronium 0.10 mg/kg. Before anesthesia induction ( T0 ), 1 min after Laryngeal Mask intubating ( T1 ), the instant of pneumoperitoneum ( T2 ), separation of the gallbladder ( T3 ), wake up immediately ( T4 ), leaving the recovery room ( T5 ), the heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded. At T4, leaving the recovery room ( T5 ), 4 hours after the operation ( T6 ), 8 hours after operation (T7), the numeric pain rating scale (NRS) were recorded. The overall amount of remifentanil and Oxycodone were record. The wake up time, additional analgetic cases and the adverse reactions were recorded. Results The average HR, SBP and DBP fluctuations in the O 2 and O 3 groups were not more than 20.00% of the basal values. There was no significant difference in wake up time between the three groups. There were 22 cases of patients, the NRS> 4, in O1 group requires additional analgesics after they wake up, more than O 2 and O 3 group (7, 3 respectively, P < 0.05). The overall Oxycodone consumption of the three groups were O1: (18.93 ± 4.34) mg (0.90~2.60 mg),O2: (25.50 ± 4.49) mg (1.40~3.00 mg), O3: (26.10 ± 4.55) mg (1.80~3.40 mg) (F = 23.79, P = 0.000). There was no significant difference in adverse reactions between the three groups, but one patient had respiratory depression in O3 group. Conclusion The optimum dose of Oxycodone for anesthesia inducing in laparoscopic cholecystectomy were 0.30 mg/kg.
