Postarthroscopy analgesia using intraarticular levobupivacaine and intravenous dexketoprofen trometamol.

PURPOSE

The aim of this prospective study was to determine the efficacy of intraarticular levobupivacaine with and without intravenous dexketoprofen trometamol for postarthroscopy analgesia.

METHODS

Sixty patients who underwent arthroscopic knee surgery were randomly assigned to three treatment groups. When the surgical procedure was completed, patients received the following treatments: group I (n = 20) patients received 20 mL intraarticular normal saline and 2 mL intravenous dexketoprofen trometamol (50 mg); group II (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous normal saline; and group III (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous dexketoprofen trometamol (50 mg). The visual analogue scale (VAS) was used, and the total analgesic consumption was assessed at 1, 2, 4, 6, 12, and 24 h post-operatively.

RESULTS

The VAS scores at 1, 2, 4, 6, 12, and 24 h post-operatively were significantly increased in group I and group II compared with group III (p < 0.05). The average VAS score during the first 24 h post-operatively was significantly lower in group III than in group I and group II (p < 0.001). Total meperidine consumption was significantly lower in group III than in groups I and II (p < 0.001).

CONCLUSION

Intraarticular levobupivacaine with adjuvant intravenous dexketoprofen trometamol administration provided better pain relief and less analgesic requirement after arthroscopic knee surgery during the first 24 h than that induced by dexketoprofen alone or levobupivacaine intraarticular alone.
