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

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: Various methods exist for treating post-operative pain which includes systemic narcotics, NSAIDS, patient-controlled analgesia, regional anaesthesia techniques, epidural local anaesthetic – narcotic mixtures, cryoanalgesia, transcutaneous electric nerve stimulation, psychological methods. Various opioides intrathecally and epidurally have been tried for post-operative analgesia. These include - morphine, pethidine, pentazocine, methadone, tramadol, Fentanyl, sufentanyl. In present study, we tried to find out analgesic effectiveness of intrathecal Fentanyl for post-operative analgesia, combined with 0.5 % Bupivacaine and side effects if any, in patients undergoing lower limb surgeries. Materials and Methods: After approval from the local ethics committee and with written informed consent from patient, a randomized controlled prospective study is carried out in the medical college and hospital.100 patients belonging to American Society of Anesthesiologists (ASA)classification I &amp; II, aged between 18-60 years, posted for elective lower limb surgeries, were randomly allocated for the study. Group-I: 50 patients received intrathecal 3 ml of 0.5 % hyperbaric Bupivacaine only. Group-II : 50 patients received intrathecal 3 ml of 0.5% hyperbaric Bupivacaine and Fentanyl 25 mcg.The patients studied across the group did not vary much with respect to age,height, weight and sex distribution. Results: The onset of sensory blockade was faster by 1.27 min in Group-BF. The perioperative and postoperative hemodynamic parameters were comparable in both the groups. The sensory analgesia in Group II was significantly prolonged by 159 mins, thus increasing the duration of analgesia. The time of first request of analgesics by the patients in group-II is prolonged compared to group-I thus prolonging the duration of analgesia. Analgesic requirement is also reduced in study group in early post-operative period. The onset of motor block was faster when Fentanyl was added to intrathecal Bupivacaine and it was 1.1 min earlier in study group. The duration of motor block to Bromage III was prolonged by almost 22 min in study group as compare to control group. Visual analogue scores were significantly lower in group-II compared to group-I after two hours of surgery thus reducing the frequency of supplemental postoperative analgesics. Conclusion: With the present study we can summarize that intrathecal Fentanyl potentiates the action of Bupivacaine thereby bringing about better quality and longer duration of analgesia, intense motor block, no hemodynamic disturbance and better postoperative outcome with/ minimum side effects.

ABSTRACT Clonidine, a centrally acting α2 adrenergic agonist has been under use as an adjuvant with hyperbaric bupivacaine for prolonging analgesia and maintaining hemodynamic stability during lower limb orthopedic and lower abdominal surgeries. The purpose of our study was to compare the efficacy and safety of intrathecal Clonidine 50 and 75 μg as adjuvant to hyperbaric Bupivacaine 15 mg (3 mL), and hyperbaric Bupivacaine 3 mL with saline 0.5 mL for onset and duration of anesthesia, hemodynamic stability, and side effects if any. This prospective randomized controlled study was conducted on 120 patients scheduled for lower limb orthopedic surgeries under spinal anesthesia. The study population was divided into three groups with 40 patients in each group. Group I (controlled group) received 3 mL (15 mg) of 0.5% Bupivacaine heavy and 0.5 mL of normal saline. Group II received 50 μg of clonidine followed by Bupivacaine 0.5% 3 mL (15 mg) and group III received 75 μg of clonidine followed by Bupivacaine 0.5% 3 mL (15 mg) intrathecally. Time taken for onset of sensory and motor blockade, duration of anesthesia, and any perioperative and postoperative complications was noted. We found that clonidine 75 μg given prior to bupivacaine, 3 mL, significantly prolongs the duration of anesthesia with minimal changes in hemodynamic parameters and postoperative complications.
