Abstract:Purpose: Levobupivacaine showed a lower risk of cardiovascular and central nervous system (CNS) toxicity than bupivacaine which is the most popular local anesthetic agent in obstetric practice. The aim of this study was to investigate the clinical efficacy of levobupivacaine compared with hyperbaric bupivacaine for spinal anesthesia for cesarean section. Methods: 60 pregnant women in ASA I -II group scheduled to have elective cesarean operation were allocated into the study. Patients were randomly divided into… Show more

“…So, their finding was similar to our finding. Similar to our study was the finding of Gulen Gular et al [8] In our study, onset time to T 10 level sensory block (mins) was significantly prolonged in Gr A compared to Gr B. In the study done by F. Erdil et al, [9] the onset time to T 10 level sensory block was significantly shorter in Bupivacaine group than in Levobupivacaine group.…”
Background and Objectives: Bupivacaine is available as a racemic mixture of dextro and levobupivacaine. Many studies show that dextrobupivacaine has greater cardiovascular and central nervous system toxicity than levobupivacaine. The objectives of the present study were to compare the effects of racemic Bupivacaine + Fentanyl and Levobupivacaine + Fentanyl on the complete regression of motor block, onset time to reach T10 level sensory block, duration of T10 level sensory block, onset time of motor block, duration of sensory block.Materials and Method: The study was conducted in 100 patients undergoing transurethral resection of prostate operation, who received either 1.75 ml Bupivacaine (0.5%) + 25 µg Fentanyl (Gr A) or 1.75 ml Levobupivacaine (0.5%) + 25 µg Fentanyl (Gr B) intrathecally.Results: Time to complete regression of motor block, onset time toT10 level sensory block were significantly prolonged in Gr A compared to Gr B. The onset time of motor block was significantly shorter in Gr A compared to Gr B. There was no statistically significant difference between the two groups in respect to the duration of T10 level sensory block, duration of sensory block.Conclusion: Intrathecal Levobupivacaine + Fentanyl used in the present study can be considered as a suitable alternative to Bupivacaine + Fentanyl for spinal anaesthesia in elective TURP surgery.

“…These results were comparable with other studies. [1][2][3][4] In this study, time of onset of sensory analgesia up to T 6 was 12.07 ± 5.95 min and 17.52 ± 8.3 min in Group B and Group L, respectively. Onset of sensory analgesia at T 6 was slower in Group L than Group B.…”

“…After preloading with injection ringer lactate 10 ml/kg intravenously, patients were shifted into operation room and again vitals measured. After appropriate monitors were attached, spinal anesthesia was given with 23 gauge spinal needle at L [3,4] space in the lateral position. The person assessing the patients was blinded for the group to which the patient belonged.…”
BACKGROUND Levobupivacaine has equal potency as bupivacaine but lower CVS and CNS toxicity. Aim was to evaluate clinical efficacy of isobaric levobupivacaine with or without fentanyl in spinal anaesthesia for inguinal hernia surgeries regarding sensory-motor block characteristics, haemodynamic profile and complications. MATERIALS AND METHODS After approval from institutional ethical committee (IEC) and informed written consent, a randomised double blinded controlled trial was conducted during 1 year period. 60 patients of ASA I-II of age 20-60 years, weight 40-90 kg, were divided into two groups 30 each, to receive either 4 mL of 0.5% isobaric levobupivacaine (group L) or 4 mL of 0.5% isobaric levobupivacaine + 25 μg fentanyl (group LF) intrathecally. Exclusion criteria-uncooperative patient and patient refusal, h/o allergy to study drugs, vertebral deformity, morbid obesity and any other associated systemic illness. Patients were monitored for sensory and motor block characteristics, postoperative analgesia, haemodynamics, side effects and complications. Data analysed by using Student t test and Chi square test; p<0.05 was considered as statistically significant. RESULTS Onset of sensory block and time to reach peak sensory level was shorter in group LF (6.40 ± 0.67 and 7.17 ± 0.79 min.) as compared to group L (8.20 ± 0.76 and 9.27 ± 0.98 min.) (p=0.00). Onset of motor block was shorter in group LF (8.57 ± 1.04 min.) compared to group L (9.10 ± 0.92 min.). Duration of analgesia was prolonged in Group LF (152 ± 3.89 min.) compared to Group L (142.30 ± 18.4 min.), (p=0.007). Haemodynamic variables and demographic data were comparable in both groups. CONCLUSION Isobaric levobupivacaine in spinal anaesthesia produces effective sensory-motor block of sufficient duration with stable haemodynamic profile in lower abdominal surgeries. Addition of fentanyl to levobupivacaine results in shortening of onset time, increased peak sensory level and prolonged duration of analgesia.
