Clinical Trial Summary

Multimodal anesthetic drug injection has been used extensively and the results of many studies suggest that postoperative pain can relief and improve the postoperative satisfaction of patients. Adrenaline is a combination of multimodal anesthetic cocktail to relieve pain. It is believed that Adrenaline causes vasoconstriction, reduces absorption of anesthetic drug into the system circulation. Currently, a comparative study on the effect of pain reduction of Adrenaline injection in the anesthetic cocktail is relatively low. There are different doses in each institution. In addition, the use of new anesthetic is Levobupivacaine that has more vasoconstrictive effect compare with traditional Bupivacaine. It also reduces the side effects of systemic and cardiotoxic effect. Therefore, the investigators think that It may not be necessary to mix Adrenaline in the multimodal anesthetic drug. Levobupivacaine already to avoid the potential side effects of Adrenaline.


Description:

The patients will be divided into two groups. In group 1, the multimodal anesthetic cocktail consisted of 100 mg Levobupivacaine (0.5%, 20 mL) and 30 mg ketorolac (1 ml). In group 2, the multimodal anesthetic cocktail consisted of 100 mg Levobupivacaine (0.5%, 20 mL), 30 mg ketorolac (1 ml) and 0.6 mg 1:1000 epinephrine (0.6 ml). Both groups were mixed with a 0.9% normal saline solution to a total volume of 100 ml. The outcome research assistant who collects data was blinded to the treatment groups. Patients will be treated with the routine standard regimen for total knee arthroplasty. Surgeons will use same surgical techniques through a standard medial parapatellar approach. In addition, standardized posterior-stabilized TKA (Zimmer Nexgen LPS flex) was used in all patients. After bone cutting before inserting the actual implant, the assistant scrub nurse in the operating room will open the envelope that the patient was classified in group 1 or group 2 and perform mixing according to the prescribed medication. The doctor who undergoes surgery was blinded. The anesthetic cocktail was divided into 4 parts 25 ml each and it was injected into 4 areas. First 25 ml cocktail was injected into the posterior capsule (P), posteromedial (PM) and posterolateral capsule (PL). The second part was injected into the medial gutter (M). The third part was injected into the lateral gutter and the forth part was injected into quadriceps muscle, retinacula tissues, pes anserinus, suprapatellar and infrapatellar fat pads (A). During the first 48 hours, all patients received intravenous morphine prn for pain, as well as dynastat, Tylenol with codeine, as required, for control of pain. After 48 hours, the pain was controlled by oral intravenous morphine and medication as requires until the patient was discharged from the hospital.

The primary outcome measure was the severity of postoperative pain during the first 48 hours after surgery. The pain was assessed by a Visual Analogue Scale (VAS) ranging from 0 (no pain) to 10 (extreme pain) every 6 hours postoperatively. Secondary outcome measures compared the consumption of intravenous morphine, which was measured every six hours in 48 hours after surgery. Additionally, blood loss in the drain at 24, 48 hours was recorded. Any complications following surgery were recorded.
