Abstract
This study was carried out on 60 patients aged more than 60 years undergoing orthopedic lower limb surgery in Emergency Hospital, Mansoura University. A routine preoperative assessment was done. The studied patients were randomly classified into 2 groups : BG (n=30) : 3 ml of hyperbaric bupivacaine 0.5% (15 mg) was injected. RG(n=30) : 2 ml of isobaric ropivacaine 0.75% (15 mg) added to 1ml glucose 5% (to give 3 ml solution containing 5 mg ropivacaine + 17 mg glucose/ml). The patients in both groups were observed for: Sensory block (duration, level and recovery), degree of motor block (according to Bromage score), the hemodynamic parameters (including MAP, HR, CVP and SpO2), analgesia (assessed by VAS) and side effects (nausea, vomiting and shivering). In the results of our study, we found that there was a significant decrease in MAP in BG at 5, 15 and 30 minutes compared with the basal value but in RG there was insignificant differences in MAP compared with the basal value. There was insignificant difference as regards time of onset of sensory block or peak sensory level reached in both BG and RG. There was no difference in potency of motor block or adequacy of sensory block between both groups. There was a significant difference in the duration of sensory and motor block as there was faster recovery from motor and sensory block in RG. Also, there was a significant difference in duration of analgesia between RG and BG. The duration of analgesia in BG is longer than in RG.
