Levobupivacaine and levobupivacaine-morphine with normal nerve block in total knee replacement in postoperative patient controlled analgesia

Levobupivacaine and Levobupivacaine-Morphine With Normal Nerve Block In Total Knee Replacement In Postoperative Patient Controlled Analgesia Aim: We aimed to investigate the effect of analgesics and on the requirement of additional medication with femoral nerve block nerve catheter through the phenomenon of postoperative patient-controlled analysis of levobupivacaine (% 0.5) and levobupivacaine (% 0.5) + morphine (1 mg) after operation application control, total knee replacement with ultrasound in postoperative patient controlled analgesia. Materials and Methods: A total of 40 patients, ages ranging from 18 to 75 were enrolled, with the approval of the Ethics Committee approval by Çukurova University Faculty of Medicine, interpreters and volunteers, for knee replacement surgery done by the department of orthopedics and traumatology. The patients were randomly divided into two groups. Sodium thiopental anesthesia was induced in all patients (3-5 mg / kg) and for gerçekleştirildi and neuromuscular blockade vecuronium (0.1 mg / kg). Anesthesia was maintained with sevoflurane in oxygen + nitrous oxide +. After the operation with ultrosan before the group II (n = 20), 20 ml of 0.5% levobupivacaine, group II (n = 20), 20 ml of 0.5% levobupivacaine + 1 mg of morphine after the femoral nerve and femoral nerve block catheter 6 ml / h 5% levobupivacaine + 0.05 ml / kg of morphine administered by patient-controlled analgesia. Intraopperatif patients with sevoflurane consumption and postoperative hemodynamic parameters 1.15,30,60 minutes, 2,4,6,12,18 hours, hemodynamic parameters, pain levels (VAS), analgesic requirements, and side effects of sedation levels and leg movements were recorded engine. Postoperative follow-up 2 after hours of Orthopaedics and was admitted to T raumatology, 18th catheter was removed 24th hours was continued for hours. Findings: Demographic data and hemodynamic parameters and the side effects of sedation levels were similar. Postoperative visual analogue scale values used levobupivacaine + morphine group were significantly lower than those used only levobupivacaine (p<0,05). Engine block also occurred in this patient group more than the other, but it did not affect postoperative mobility. Although similar to the total amount of local anesthetic used in patients with morphine analgesic demand added to the group were lower than the other group. Result: Postoperative femoral nerve block in patients undergoing total knee replacement and after analysis, PCA is an effective method is applied through the catheter. More effective analgesia with morphine was added to the local anesthesia, and patients with reduced need for additional mobilization of the affected anesthetic prolonged duration of motor block level.
