Background: This study was conducted to compare and evaluate the caudal epidural clonidine when mixed with ropivacaine and bupivacaine in prolonging postoperative analgesia in children of Indian genotype undergoing hypospadias surgery, as well as compare the intraoperative haemodynamics using caudal bupivacaine with clonidine vs ropivacaine with clonidine. The study was also aimed at studying the side effects and the duration of post-operative pain relief of bupivacaine with clonidine v/s ropivacaine with clonidine. Methods: This is a prospective randomised comparative study that was carried out in the Department of Anaesthesiology, KEM Hospital, Pune, over 12 months (from October 2016 to September 2017), among 56 children having an ASA Grade of II, aged between 1 to 8 years admitted for hypospadias surgery. The data gathered was cleaned using Microsoft Excel, before statistical analysis was done. Results: It was observed that caudal epidural analgesic duration was more in the bupivacaine clonidine group than in the ropivacaine clonidine group. The sedation score was higher at the second hour in the bupivacaine clonidine group. The HR and mean arterial pressure values were found to be notably higher in the ropivacaine clonidine group than those in the bupivacaine clonidine group. Intraoperatively and postoperatively, there was a decrease in pulse rate and MAP but at no time did the value reach the criteria for intervention. Other side effects like postoperative vomiting, nausea, motor blockade, respiratory distress not observed in any group. Conclusion: Bupivacaine 0.25 % 0.5 ml per kg with clonidine 1 microgram / kg via caudal route increased the duration of postoperative analgesia with no adverse effects as compared to ropivacaine 0.25 % with clonidine 1 microgram/ kg. Hence clonidine is more efficient in increasing postoperative analgesia when added with Bupivacaine as compared to ropivacaine in Indian genotype in hypospadias surgery.

Background: Extensive use of ultrasonography for block execution has increased the success of procedure due to direct visualization of anatomical structures. Infra-clavicular brachial plexus block can be an attractive alternative to supraclavicular nerve block for upper limb surgeries. The objective of our study was to assess and compare the efcacy and success rate of USG guided technique versus PNS technique in Infra-clavicular brachial plexus block. Material And Methods: 70 adult patients with age in the range of 18-60 years, weight 50-80 Kg, ASA Grade I & II posted for elective upper limb surgeries of hand, wrist, forearm and distal arm under infra-clavicular brachial plexus block. Group P (PNS)– Nerve stimulator guided Infraclavicular brachial plexus block. Group U (USG)– Ultrasound guided Infraclavicular brachial plexus block. Block execution time, sensory blockade, motor blockade and success rate were assessed. Assessment of sensory blockade was done by Hollmen scale whereas motor block assessment was done by Bromage Scale. Results: There was statistically signicant difference between the groups for block execution time, onset of sensory and motor blockade, time for complete sensory and motor block and success rate(p<0.05). Conclusion: We conclude that, Ultrasound guided infraclavicular nerve block has shorter block execution time, faster sensory and motor block onset, signicantly earlier complete sensory and motor blockade, higher success rate with lesser pricks and minimal complications and should be preferred over PNS technique.

BACKGROUND Studies suggest that clonidine can improve the duration of analgesia, quality of pain control when used with ropivacaine for caudal blocks in children. This study was designed to understand the effects of caudally administered ropivacaine 0.25 % (1ml/kg) alone and ropivacaine 0.25 % (1ml/kg) with clonidine 2 mcg/kg, in children between 2- 10 years. METHODS Sixty children posted for various sub-umbilical surgical procedures were included after written informed consent and ethics committee approval. Children were randomly divided into 2 groups of 30 each: Group R —ropivacaine 0.25 % 1 ml/kg into caudal epidural space and Group RC—ropivacaine 0.25 % 1 ml/kg and clonidine 2 mcg/kg into caudal epidural space. RESULTS The mean age of patients was similar with no statistical difference (4.83 vs 5.36, P = 0.3353). The duration of anaesthesia was significantly longer in the RC group (544.83 minutes vs 268.00 minutes, P < 0.0001). The effect size was very high (Cohen d=23.86). The pain score was comparable up to 1 hour for the two groups. But 2 hours later, the pain scores were significantly lower for the ropivacaine and clonidine groups. The effect on motor blockade was similar in both groups with no motor blockade at 4 hours follow up. 5 cases of urinary retention were seen in the study with no statistically significant difference in terms of complication rate between the two groups. No case of hypotension or bradycardia was seen. There was a significant difference between the two groups in terms of cardiovascular parameters (HR, SBP, DBP) after administration of drugs. CONCLUSIONS The addition of clonidine to ropivacaine for caudal blocks in children was associated with better quality of pain control and a longer duration of analgesia without any additional motor blockade. There was no significant difference seen in terms of complication. KEY WORDS Analgesia Duration, Caudal Analgesia, Clonidine, Pain Control, Ropivacaine.

Background: Alpha-2 adrenergic agonists used as adjuvant to spinal anaesthesia produce substantial sensory and motor blockade of bupivacaine. This study was planned to compare the sensory and motor blockade characteristics of intrathecal combinations of adjuvants dexmedetomidine and clonidine with hyperbaric bupivacaine in the cases who underwent lower limb surgery under spinal anaesthesia.Methods: This was prospective, randomized, double blind study. 90 patients of age group between 18-60 years, ASA grade I and II were allotted into 3 equal groups. Group B received 15 mg bupivacaine plain, group BD and BC received dexmedetomidine (5mcg) and clonidine (50mcg) as adjuvants to bupivacaine respectively.Results: The duration of 2 dermatome regression time, sensory blockade and motor blockade were longest in dexmedetomidine group (129.37±4.87; 386±58.43; 353±48.87) in compared to clonidine (109.77±5.95; 296.53±57.19; 269.7±51.2) and bupivacaine group (81.03±6.83; 211.1± 30.47;181.03±20.8). Both drugs do not affect the peak level of sensory blockade, sensory block onset and motor block onset time. Dexmedetomidine and clonidine do not cause sedation in intraoperative and postoperative period.Conclusions: We conclude that addition of dexmedetomidine and clonidine in spinal anesthesia with hyperbaric bupivacaine increase the duration of ‘2 dermatome regression’ time, sensory and motor blockade and both are more with dexmedetomidine than with clonidine.

Epidural analgesia is the most commonly used method for surgical anesthesia, obstetric analgesia, post-operative pain control, and chronic pain management. These epidurals are used either as a single-shot technique or with the catheter that allows intermittent boluses or continuous infusion, or both. All of these variables are controlled by choice of drug concentration, dosage, and level of injections. To compare the onset and duration of sensory block, motor block, and post-operative analgesia duration using Ropivacaine with Tramadol and Ropivacaine with Midazolam in the Epidural technique. In this prospective, non-randomized, comparative study, the total of 160 patients who underwent surgeries below the umbilicus did under epidural technique at Govt. Kilpauk Medical college hospital a Govt. Royapettah hospital, Chennai, was screened. Patients were divided into two groups. Patients in Group R received an epidural injection of 0.5% Ropivacaine (30ml) with Tramadol 2 mg/kg, whereas patients in Group L received an epidural injection of 0.5% ropivacaine (30ml) with Midazolam (50mg/kg). On studying the comparison of the onset of sensory, motor blockade, and duration of the sensory-motor blockade in the two groups, the onset of sensory blockade, motor blockade, and duration of motor blockade was more among ropivacaine with midazolam group. In comparison, the duration of sensory blockade was more among ropivacaine with tramadol group. A statistically significant difference in onset of sensory, motor blockade, and duration of sensory blockade across the group was found (p&#60;0.005). Tramadol or Midazolam's addition to caudal epidural block with ropivacaine showed significant prolongation of post-operative analgesia compared to ropivacaine alone. The mean duration of analgesia was more among ropivacaine with the Tramadol group.

BACKGROUND Isobaric levobupivacaine has minimal effect on positional variation of sensory and motor blockade given intrathecally. Also, it has lesser cardiotoxic and neurotoxic effects. Present study was done to compare efficacy, analgesia haemodynamic effects and any adverse effects after spinal anaesthesia with isobaric levobupivacaine with nalbuphine and fentanyl as adjuvants in transurethral endoscopic surgeries. METHODS 60 male adult patients of American Society of Anaesthesiologists (ASA class I-III) of age group 40 - 80 years were randomized into 2 groups (n = 30) in this prospective, double blinded study. 10 mg of 0.5 % levobupivacaine with 25 µg fentanyl in group LF and 10 mg of 0.5 % levobupivacaine with 0.8 mg nalbuphine in group LN. Parameters assessed were sensory and motor blockade characteristics and hemodynamic variables in both the groups. Adverse effects were recorded if any. RESULTS Onset of sensory and motor blockade were significantly faster in group LF compared to group LN. In both the groups, time for two segment regression was comparable. Statistically significant prolonged analgesic duration was noticed in group with nalbuphine than fentanyl as adjuvant to isobaric levobupivacaine. Difference in haemodynamic variation was not significant in both the groups. CONCLUSIONS Intrathecal nalbuphine 0.8 mg as an adjuvant with isobaric levobupivacaine 0.5 % 10 mg is as efficacious as fentanyl 25µg in transurethral endoscopic surgeries in elderly population with better hemodynamic stability.

Objective: Intrathecal magnesium as an adjuvant to hyperbaric ropivacaine could extend duration of sensory blockade and improve the quality of post-operative analgesia; thereby reducing opioid requirements and its adverse effects. Hence, we conducted this prospective, randomized, double-blind clinical trial to observe its effects for day care surgeries. Methods: After obtaining institutional ethical committee approval and registration of trial, patients’ informed consent was taken and eighty adult patients of either gender, ASA 1 and 2, posted for infra umbilical surgeries were divided into two groups: Group RM received 3 ml hyperbaric Ropivacaine with 0.75 ml magnesium sulfate (75 mg) and Group R received 3 ml hyperbaric Ropivacaine with 0.75 ml sterile water. Sensory and motor blockade parameters, hemodynamic variables, and adverse effects were monitored, analyzed using appropriate statistical tests. Results: Total duration of sensory blockade was significantly prolonged in Group RM compared to Group R (242.8 ± 9.9 versus 186.6 ± 8.4 min) (***p<0.001). Complete motor regression was observed significantly earlier in Group RM than in Group R (151.3 ± 7.8 versus 184.7 ± 5.6 min) (*p<0.05). Post-operative pain free interval was significantly prolonged in group RM compared to group R (725.2 ± 18.6 vs. 515.2 ± 17.8 min) (***p<0.001). Conclusion: We concluded that intrathecal magnesium as an adjuvant to hyperbaric Ropivacaine significantly prolonged both sensory blockade duration, post-operative pain-free interval without increasing motor blockade duration and the incidence of adverse effects.

Objective: To determine the effectiveness of dexmedetomidine on the spinal anaesthesia as an adjuvant to the hyperbaric levobupivacaine in patients undergoing cesarean section. Study Design: Comparative/Observational Place & Duration: The study was conducted at Anesthesiology/Obstetrics and Gynaecology departments of Mayo hospital, Lahore for duration of six months i.e from 1st November 2020 to 30th April 2021. Methods: This analysis included a total of 120 cases. After the informed consent the patients had received comprehensive demographics. Three equal classes of patients were divided into groups A, B and C. Group I had 40 patients and received 2.5 ml isobaric levobupivacane, group II with 40 patients and received 2.5 ml isobaric levobupivacaine and 5μg dexmedetomidine, and group III received 2.5 ml isobaric levobupivacaine and 25 μg fentanyl intrathecally. The outcomes of these groups were analysed in which sensory and motor blockage period were measured from the time the intrathecal drugs were administered. The full SPSS 26.0 version was used to analyze the results. Results: The mean age of the patients in group I was 27.44 ± 7.64 years with BMI 23.19±8.44, mean age in group II was 27.22 ±7.42 years with BMI 24.44 ± 6.16 and in group III mean age was 26.99 ±9.61 years with BMI 24.72 ±4.34. Duration of sensory and motor blockade was observed and resulted that it was earlier in group III as compared to group I and II. Prolonged duration of sensory and motor blockade was observed in group II as compared to groups I and III with significantly P value< 0.001. Conclusion: We concluded that for an adjuvant of 0.5 percent isobaric levobupivalacaine, Intrathecal dexmedetomidine induces both prolonged motor blockage and post operative analgesia than fentanyl.

Introduction:- Ketamine and Fentanyl used intrathecally as adjuvant to 0.5% hyperbaric bupivacaine for patients undergoing TAH to shorten the onset of sensory and motor blockade and prolonging the duration of block. Aims and Objective:-We evaluated onset and duration of sensory and motor blockade and timing of regression of sensory blockade to T 12 and motor blockade to Bromage scale 3. Material and Methods:-This analytical Comparative Study was conducted in Department of Anaesthesiology, Era’s Lucknow Medical College and Hospital, Era University, Lucknow over a period of eighteen months from 2016 -2018 following approval from institutional ethical committee and written informed patient consent. The sample size of 162 female patient aged 40 to 60 years, belonging to ASA physical status 1 and 2 undergoing TAH were randomly allocated to three groups in double blind manner. Group I Received Inj. Bupivacaine (0.5% Heavy) 3.0ml + Inj. Ketamine (25 mg), Group II Received Inj. Bupivacaine (0.5% Heavy) 3.0 ml + Inj. Fentanyl (25 µgm), Group III (Control Group): Received Inj. Bupivacaine (0.5% Heavy) 3.0 ml + Normal saline 0.5 ml. Onset and Duration of Sensory and Motor Blockade and time taken for regression of sensory level to T12 and motor level to Bromage scale 3 noted. Results:- The present study showed that both Ketamine as well as Fentanyl shortened the onset time and prolonged the block duration. However, with respect to onset time, ketamine has shorter onset of blockade than fentanyl. Conclusion:- Both the modalities independently assured quicker onset and prolonged duration of block, thus suggesting that adjuvant use of either of two could be beneficial. Keywords: TAH, Ketamine, Fentanyl, Bupivacaine.
