Transient neurological symptoms after spinal anaesthesia with levobupivacaine 5 mg/ml or lidocaine 20 mg/ml.

BACKGROUND: Transient neurological symptoms (TNS) after spinal anaesthesia have been reported most commonly in association with lidocaine, but have been observed with other local anaesthetics. The aim of this prospective, randomized, double-blind study was to investigate the incidence of TNS after spinal anaesthesia with either levobupivacaine or lidocaine. METHODS: Patients undergoing inguinal hernia, appendectomy, varicose vein or minor orthopaedic operations were included in the study (60 patients; 47 male, 13 female, overall mean age 30 years). All patients had an American Society of Anesthesiologists score of I or II. The patients were randomly assigned to receive spinal anaesthesia with either 20 mg isobaric levobupivacaine (5 mg/ml) or 80 mg isobaric lidocaine (20 mg/ml). Onset of sensory and motor block and side effects were recorded. On post-operative days 1, 2, and 3, patients were interviewed by an investigator blinded to the spinal anaesthetic used. The patients were classified as having TNS if, following recovery from anaesthesia, there was pain in the buttocks, thighs and/or lower limbs. RESULTS: In the levobupivacaine group, one patient (3.33%) experienced TNS, whereas in the lidocaine group, eight (26.6%) experienced TNS (P=0.002). Maximum times to arrival of sensory blocks were shorter with lidocaine (P<0.001). The levobupivacaine and lidocaine groups did not differ significantly in terms of the highest dermatome included in sensory block or motor block grade. CONCLUSION: After spinal anaesthesia with levobupivacaine, the incidence of TNS was much less than after lidocaine. However, it appears that TNS may occur in association with levobupivacaine.

Effect of locally administered lornoxicam in the management of low back pain after lumbar epidural anesthesia: a double-blind, randomized, controlled study.

AIM: Low back pain after lumbar epidural anesthesia remains an important clinical problem. Possible causes of the back pain associated with epidural anaesthesia are localized trauma, aseptic periosteitis, tendonitis, inflammation of the ligaments, and osteochondritis. Lornoxicam is a new nonsteroidal anti-inflammatory drug (NSAID) that has been shown to be effective and well tolerated in the treatment of postoperative pain. The use of locally administered lornoxicam for the relief of low back pain following lumbar epidural anesthesia has not yet been studied. Thus, the aim of the present study was to investigate the efficacy of lornoxicam in the management of pain after lumbar epidural anesthesia. METHODS: A total of 60 patients were randomized to receive either treatment with lornoxicam or to receive a control treatment. The Lornoxicam group received 12 ml of 0.5% epidural bupivacaine and 4 ml 1% lidocaine, along with 2 mg lornoxicam for local infiltration. The control group received 12 ml of 0.5% epidural and 4 mL 1% lidocaine alone for local infiltration. Following the initial preoperative evaluation, a blinded investigator assessed pain intensity at 24, 48 and 72 hours postoperatively using a Verbal Rating Scale (VRS). RESULTS: The overall frequency of low back pain after epidural anesthesia was significantly higher in control-group patients compared to Lornoxicam-group patients during the 3 days studied (26.6% and 6.6%, respectively, P<0.05). CONCLUSIONS: Our study demonstrated that local administration of Lornoxicam before epidural anesthesia for pilonidal sinus surgery decreased the frequency and severity of low back pain following lumbar epidural anesthesia with lidocaine. In conclusion, local administration of lornoxicam during epidural anesthesia may present a useful option for the relief of post-epidural low back pain.
