Introduction: Subarachnoid block is commonly employed technique for lower abdominal and lower limb procedures. Bupivacaine and ropivacaine are commonly used local anesthetics for subarachnoid block. The aim of this study is to compare the efficacy and safety of isobaric Ropivacaine over hyperbaric Bupivacaine. Methods: This was a prospective comparative study for a duration of six months. 60 ASA grade I-II adult patients between 16-60 years undergoing lower limb surgery under spinal anesthesia were randomized into two groups. Group I including patients who received 15 mg of hyperbaric bupivacaine 0.5% and group II including patients who received 22.5 mg of isobaric ropivacaine 0.75%. The onset and duration of sensory and motor block and hemodynamics including heart rate (HR), non invasive mean arterial blood pressure (MAP) and respiratory depression were recorded. Data were entered in Microsoft excel and statistical analysis was done by chi square test and T test using SPSS (version 23.0). Results: Both the groups were demographically statistically insignificant. Successful block was attained in all patients in both groups. The sensory onset and motor onset were significantly delayed in the Ropivacaine Group compared to the Bupivacaine Group P<0.001. There was no significant difference in the hemodynamics (heart rate and mean arterial pressure ). Conclusions: Though isobaric ropivacaine provided lesser degree of sensory and motor block with delayed onset compared to hyperbaric bupivacaine, it can effectively and safely used in subarachnoid block in lower limb surgeries without any major hemodynamic changes and adverse effects.

Background: Cardiovascular system may be profoundly affected by spinal anaesthesia due to unavoidable sympathetic blockade which is more prominent in elderly.A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes.Objective: To assess whether a unilateral spinal anaesthesia using 0.5% hyperbaric bupivacaine will restrict the sympathetic block to avoid the undesired cardio vascular effects.Materials and method: In this prospective study 60 ASA Ill and IV patients aged between 60-90 years undergoing unilateral lower limb surgery were included. Patients were divided into two groups. In group-A, dural puncture was performed with the patient in the lateral decubitus position with 1.5 mL of hyperbaric bupivacaine. In group-B, it was performed with the patient in a seated position using 1.5 mL hyperbaric bupivacaine. Each patient was then placed in supine position. The speed of injection was 1 mL/30s. Patients were placed in the lateral position with operated side down and kept in this position for 10 minutes. Motor and sensory levels were assessed, and haemodynamic alterations were monitored just after block, 5, 10, 15 and 30 minutes of spinal anaesthesia.Results: The demographic data were found similar in both groups. The time to the onset of the sensory and motor block was significantly shorter in group-B. The duration of motor and sensory block was significantly shorter in group-A. Haemodynamically all the parameters revealed better out come in unilateral spinal anesthesia. The incidence of complications (nausea, headache, and hypotension) was also lower in group A.Conclusion: When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during surgery on a lower limb. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.Delta Med Col J. Jan 2017 5(1): 20-24

Background: Spinal anesthesia is a preferred technique of choice in infraumbilical surgeries. The spinal anesthesia effect can be improved by adding various adjuvant like Fentanyl, clonidine, dexmedetomidine. Dexmedetomidine is a highly selective alpha 2 adrenergic agonists. The aim of study to compare efficacy and safety between Dexmedetomidine and Fentanyl with Bupivacaine.Subjects and Methods:A prospective randomized, double-blind study was conducted on 100 patient by dividing them into two groups. Group D: 2.5ml (12.5mg) of 0.5% hyperbaric bupivacaine with 5mcg (0.5ml) dexmedetomidine and Group F : 2.5ml(12.5mg) of 0.5% hyperbaric bupivacaine with 2 5mcg(0.5ml)  fentanyl. The total volume injected intrathecally was 3.0ml in ASA I and II grade patient undergoing lower limb surgery.Results:Patients in dexmedetomidine groupD had a significantly longer sensory and motor block time than patients in fentanyl group F.The mean time of sensory regression to level S1 was 306.00 ± 13 .32 in group D and 206.14± 16.69 in group F(P<0.001). The regression time of motor block to reach modified Bromage 0 was 257.70±14.61 in group D and 178.54±14.23 in group F(P<0.001).Conclusion:Intrathecal Dexmedetomidine is associated with prolonging motor and sensory block as compare to Fentanyl.

Objectives: Dexmedetomidine was shown to prolong the duration of spinal anesthesia and enhance post-operative analgesia. The aim of the study was to compare the effect of intravenous (IV) versus intrathecal (IT) administration of dexmedetomidine on bupivacaine spinal anesthesia in patients undergoing lower limb surgery.Methods: A prospective randomized controlled study was conducted during the year 2014–15. 60 American Society of Anesthesiologists physical status I–II aged 18–60 years scheduled for lower limb surgery under spinal anesthesia were assigned randomly to two groups: (1) IT group (IT group) (n=30) patients received 3 ml of 0.5% hyperbaric bupivacaine and 5 μg of dexmedetomidine intrathecally (100 μg/1 ml ampoule drawn in 40 IU/ml insulin syringe making 5 μg=2 IU=0.05 ml) and (2) IV group (IV group) (n=30) received 3 ml of 0.5% hyperbaric bupivacaine and 0.05 ml of normal saline intrathecally followed 5 min later by IV dexmedetomidine 0.5 μg/kg by infusion pump over 10 min as a single dose.Results: The IT group had a statistically significantly earlier sensory onset to T10 and shorter time from injection to highest sensory level (p<0.001). The regression times of two dermatomes, regression time to S1 dermatome and time to reach Bromage 3 motor block were significantly less in the IT group, whereas regression time to Bromage 0 was prolonged (p<0.001). The IT group showed a significantly longer time to the use of rescue analgesia and less analgesic consumption in first 24 h than the IV group (p<0.001). Furthermore, the intensity of pain was significantly less in the IT group as compared to IV group (p<0.001). Compared with IV group, the IT group had low sedation score, fewer overall side effects, which was statistically not significant (p>0.05).Conclusion: In bupivacaine spinal anesthesia for limb surgeries, dexmedetomidine, when administered intrathecally, has greater augmentation to sensory and motor block, more hemodynamic stability, better analgesic properties, and fewer overall side effects compared to the IV route of administration.

Background: Epidural administration of various analgesics gained increasing popularity following the discovery of opioid receptors in the spinal cord capable of producing potent analgesia. This effect seems to be greatest when epidural anaesthesia in continued in the post-operative period as epidural analgesia. It is now clear that epidural administration of opioids. Ours was a comparative study between epidural bupivacaine with buprenorphine and epidural bupivacaine for post-operative analgesia in abdominal and lower limb surgery. Methods: 60 patients undergoing lower abdominal and lower limb surgeries of either sex with ASA grade 1 and 2 aged between 20 and 60 years for divided into two groups. After completion of the surgery and when the effect of local anaesthetic wears of and the patients complains of pain the intended study drugs were given when visual analogue pain score touched 5 cm mark. Group – A: Patients received 8ml of 0.25% bupivacaine + 0.15mg of buprenorphine. Group – B: patients received 0.25% of bupivacaine alone. In the post-operative period the following parameters were studied, 1. Onset of analgesia, 2. Duration of analgesia, 3. Vital parameters such as heart beat, blood pressure, respiratory rate, sedation score and visual analogue score were recorded, 4. Side effects like nausea, vomiting, hypotension, respiratory depression, and pruritus allergic reaction were looked for. Results: It is observed that onset of analgesia in Group A (0.25% bupivacaine + 0.15mg buprenorphine) was 7.35 min. When compared to Group B which 15.5 min, which is statically signicant (P<0.05). Duration of analgesia in Group A is 17.23 hrs compared to Group B, which is 5.2 hrs, this is statically signicant (P<0.05). Visual analogue scale was reduced in Group A compared to Group B Conclusions: Addition of buprenorphine to bupivacaine by epidural injection for post-operative analgesia improves the onset, The duration and the quality of analgesia
