Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 2
Abstract
Introduction: Subarachnoid (spinal) block is a safe and effective alternative to general anesthesia when the surgical site is located on the lower extremities, perineum, or lower body wall. Aim: The aim of this study is to evaluate the effect of equal doses of intrathecal isobaric bupivacaine and isobaric ropivacaine in terms of duration of analgesia and hemodynamic parameters. Materials and Methods: 50 patients were randomly allocated into two groups; Group B received isobaric bupivacaine 0.5% 3 ml (15 mg) and Group R received isobaric ropivacaine 0.5% 3 ml (15 mg); American Society of Anesthesiologists I and II patients, aged 20-60 years, height: 150-170 cm, patients undergoing elective lower limb and perineal surgeries with duration <2 h were included in the study. Results: In Group B, the mean duration of sensory block is 219.9 min. In Group R, the mean duration of sensory block is 162.9 min. In Group B, the mean duration of motor block is 203.8 min. In Group R, the mean duration of motor block is 142.9 min. Conclusion: Ropivacaine is an ideal drug for ambulatory anesthesia and a good alternative to bupivacaine for surgeries of short duration.
