Methods: Preoperatively the lowest pulseoximeter saturation (SpO_2) under room air breathing was measured after 2 μg/kg of fentanyl givenintravenously in 35 patients who were scheduled with continuous intravenous morphine analgesia (12μg·kg^(-1)·h^(-1)) postoperatively. Results: The test dose fentanyl resulted in respiratorydepression in 19 of 35 cases, while 8 (42.1%) of the 19 cases developed respiratory depressionpostoperatively. However in the rest 16 patients, no patient (0) developed respiratory depression (P< 0.01). The fentanyl-induced lowest SpO_2 significantly correlated with the lowest SpO_2postoperatively (P < 0.01). The analgesia effect in terms of verbal analogue scale was correlatedneither with the fentanyl-induced lowest SpO_2 nor with the lowest SpO_2 postoperatively (P > 0.05).Conclusion: The patient who was sensitive to fentanyl-induced respiratory depression would take ahigh risk to develop postoperative respiratory depression with intravenous morphine analgesia andthe patient with respiratory depression does not always go with satisfactory analgesia.展开更多

Methods Thirty-nine patients scheduled for abdominal surgeries were randomly assigned to different PCA treatment groups using either lornoxicam or fentanyl postoperatively. Pain intensity difference (PID) and sum of pain intensity difference (SPID) were used to assess the analgesic efficacy of both drugs during a 24-hour period. Results The analgesic efficacy of lornoxicam is 1/66 of fentanyl, which was shown by SPID value of 3.250 and 3.058, respectively (P > 0.05). Lornoxicam caused fewer adverse events than fentanyl (33% vs. 68%, P < 0.05). Conclusion In clinic, we can use lornoxicam to treat postoperative pain effectively and with less adverse reactions com-pared with fentanyl.展开更多
