Background: Abdominal hysterectomy is often a long duration procedure and warrants intense pain relief in the post-operative period. Dexmedetomidine when added to bupivacaine in subarachnoid block prolongs the duration of surgical anaesthesia, decreases blood loss and prolongs duration of post-operative pain relief. Aims and Objective: To compare two different doses dexmedetomidine as an adjuvant to bupivacaine in sub-arachnoid block in abdominal hysterectomy surgeries. Materials and Methods: 60 patients of age group 30-60 years posted for elective abdominal hysterectomies under American Society of Anaesthesiologists (ASA) physical classification I or II were randomly allocated into 2 groups of 30 each. Group A received 5 micrograms (μg) of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Group B received 10 μg of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Changes in blood pressure, heart rate, respiratory rate, oxygen saturation, ephedrine consumption, blood loss, duration of sensory block, duration of motor block, duration of analgesia were compared between two groups. Results: There was no significant difference in change in heart rate, respiratory rate, oxygen saturation, duration of sensory block, duration of motor block between two groups. Patients in group B had significant decrease in blood pressure, blood loss and significant increase in ephedrine consumption compared to Group A. The duration of analgesia was also prolonged in group B compared to Group A. Conclusion: Dexmedetomidine in dose of 10 μg is a better adjuvant to bupivacaine for abdominal hysterectomy surgeries.Asian Journal of Medical Sciences Vol.8(2) 2017 59-63

 To study the analgesic efficacy and side effects of Tramadol for painless labor in combination with Bupivacaine. Randomized, controlled, double blind, open prospective study conducted at Department of Obstetrics and Gynaecology, Chitwan Medical College from July 1st 2015 to June 30th 2016. 100 patients of ASA Grade I and II, aged between 20-35 years willing for epidural analgesia for labor pain were included in the study. They were divided into two groups: Group A- Control group and Group B- Study group. Subjects of Group A received 10 ml of 0.25% Bupivacaine and that of Group B received 10ml of 0.25% Bupivacaine with 1mg/kg body weight of tramadol. Analgesic efficacy was assessed by Visual Analogue Scale (VAS) and other vital parameters (Blood Pressure, Heart Rate and Respiratory Rate) before the administration of the drug and at different time intervals of 0, 5 min, 10 min, 15 min, 30 min, 45 min, 60 min and every hourly up to maximum of 5 hrs. Neonatal out comes were assessed by the use of APGAR scores and the side effects of the drugs in two groups were also evaluated. Total number of patients was 100, of ASA Grade I and II, aged between 20-35 years. The mean age of patients in Group A was 23.54 ± 3.74 years and 24.22 ± 3.64 years in Group B. Mode of delivery was spontaneous vaginal in 42 patients (84%) in group A and 45 patients (90%) in group B. Instrumental vaginal delivery was done in 1 patient (2%) of group A and none of group B. Cesarean section was done in 7 patients (14%) of group A and 5 patients (10%) of group B. There was no significant difference in heart rate, blood pressure and respiratory rate at various time intervals. Pain score of Group B was significantly less at 60th min and had lower values than Group A at various time intervals. Time for first top up was significantly delayed and the total dose of bupivacaine was significantly lower in Group B patients but the incidence of nausea and vomiting was significantly high among Group B patients. At one minute majority of the babies of group A had mean APGAR score 6.98 ± 0.55 versus 7.18 ± 0.60 in group B. At 5 minute, Group A had mean score of 8.02 ± 0.47 versus 8.22 ± 0.58 in Group B. There were no significant differences in 2 groups. In both the groups there was no significant effect on duration of second stage of labor and it wasn’t prolonged in any of the patients. Epidural anesthesia with bupivacaine and tramadol provided better pain relief and reduced the total dose of bupivacaine in majority of the patients with no adverse effects on mother and fetus. As tramadol is cheap, safe and effective, it can be considered as a better option to improve quality of pain relief during labor.

We aimed to determine the usefulness of intrathecal pethidine as the sole anaesthetic for transurethral resection of prostate (TURP) while comparing the incidence of hypotension with intrathecal bupivacaine. A double-binded randomized prospective trial was conducted involving 40 patients for TURP. The patients were divided equally into two groups; group A received 2 ml 0.5% bupivacaine intrathecally and group B received 40 mg pethidine intrathecally. Changes in blood pressure and heart rate were measured over the first 30 minutes. The highest sensory block and the time to reach it were documented. The degree of motor blockade was also recorded. There was no significant difference in the incidence of hypotension. The pethidine group had significantly greater reduction in heart rate, a lower degree of motor block, shorter period before requests for postoperative analgesia but a higher incidence of sedation, nausea and vomiting. Intrathecal pethidine did not offer any advantage over intrathecal bupivacaine for TURP.

Background In obstetrics, pregnancy induced hypertension is still a burning question and complicates a large number of pregnancies in developing countries. Chance of hypotension is more in patients getting magnesium sulfate with subarachnoid block but it may be managed with adequate preloading and by pressor agent ephedrine. Objectives This study was designed to observe the effect of magnesium sulphate on quality of subarachnoid block in terms of onset and duration of motor and sensory block, APGAR score of the neonates and haemodynamic status of the patients. Methods Sixty parturients undergoing caesarian sections under subarachnoid block were enrolled for the study. They were divided into two groups. Group-A include normal parturient undergoing caesarian section and group-B include pre-celamptic parturient treated with magnesium sulphate within 1 to 2 hours before block. After recording of base line haemodynamic status (BP, HR, SPO2) all patients received subarachnoid block with 2 ml (10 mg) hyperbaric bupivacaine at L3-4 level. Onset of sensory block was assessed by using pinprick, onset of motor block was assessed by onset time of weakness of lower limb and onset time of complete paralysis of lower limb after SAB. Duration of motor block was assessed by modified bromage scale. Height of the block was assessed by using pin prick at the intercostals space in the mid axillary line after 5 minute of SAB. Neonatal assessment was done by using apgar score in 1 and 5 minutes after delivary of baby. Blood pressure was recorded normally at 2 min interval until 15 minutes then every 5 minutes interval till the surgical procedure is completed. Results Duration of motor block in group B is significantly higher 276 ± 44.92 min compared with group A which was 197.96 ± 24.25 min (P = 0.000). Duration of sensory block in group B also significantly higher with 308.76 ± 61.43 min compared with group A which was 264 ± 30.57 min, and (P = 0.001). Changes in systolic blood pressure in group B patient is more and highly significant (P < .05), for upto 60 min. But changes in diastolic blood pressure in-group B was only highly significant with group A for upto 9 minutes. APGAR score was significantly low both in 1 minute and 5 minutes, in group B patients which was 5.80 ± .61 at 1 minute and 7.73 ± .827 at 5 minutes and in group A which was 6.60 ± .85 at 1 minute and 8.30 ± .595 (mean ± SD) at 5 minutes. Onset of sensory block and onset of motor block revealed on significant difference between groups. Conclusions Chance of hypotension is more in patients getting magnesium sulfate but it may be managed with adequate preloading and by pressor agent ephedrine. APGAR score of baby of magnesium sulfate getting patient is low but it is acceptable.

Abstract Background Brachial plexus block has substituted general anesthesia in the majority of patients planned for upper limb surgeries as it avoids the undesired effects of the medications used in general anesthesia as well as the stress response associated with airway manipulation. Opioid agonist–antagonists such as nalbuphine are used as adjuvant to improve the anesthetic properties of bupivacaine. Verapamil has an additive effect in brachial plexus blockade in the form of decreasing the consumption of analgesics in the postoperative period with reducing onset time and extending the duration of motor and sensory blockade. The aim of this study is to investigate the adjuvant effect of verapamil versus nalbuphine to 0.5% bupivacaine in brachial plexus block as regards onset, duration of sensory and motor blockade and postoperative analgesic augmentation. The study is randomized, prospective, double-blinded, comparative study where 90 patients subjected to arm, forearm and hand surgeries were randomized into three groups, group A received 30 ml of plain bupivacaine 0.5% plus 2 ml of normal saline, group B received 30 ml of bupivacaine 0.5% plus 2 ml verapamil equivalent to 5 mg, group C received 30 ml of bupivacaine 0.5% plus 10 mg of nalbuphine diluted in 2 ml of normal saline. Results Results of this study showed that group C and group B sensory block time onset was 7.25 ± 1.5 vs. 10.92 ± 3.84 min, P < 0.001 and was shorter than that in group A (13.2 ± 2.66 min). In addition, the motor block onset was (11.10 ± 1.24 vs. 13.50 ± 3.77 min, P < 0.001) shorter than group A (17.16 ± 1.30 min). In group C and group B, sensory block duration was 396 ± 32.17 vs. 355.83 ± 18.48 min, P < 0.001, respectively and was longer than that in group A (321.13 ± 25.08 min). Also, there was prolonged motor block duration in group C and group B recording (338.92 ± 25.2 vs. 302.93 ± 15.24 min, P < 0.001) and was longer than that in group A (280.70 ± 32.35 min). Time of demand of rescue analgesia dose was significantly long in group C and group B (449.53 ± 52.45 vs. 418.13 ± 41.12 min, P < 0.001) and was longer than group A (361.31 ± 21.42 min). Both verapamil and nalbuphine have additive effect to bupivacaine improving the all anesthetic parameters of the block. Conclusion Both drugs produce favorable enhancement of time onset and effective prolongation of duration of sensory and motor blockade and extend the period of postoperative analgesia with superiority to nalbuphine over verapamil.

INTRODUCTION Abdominal hysterectomy (AH) is a quite common gynaecological surgical procedure and electively done under central neuraxial blockade. AH is performed for malignant as well as benign indications such as uterine leiomyoma, persistent vaginal bleeding, or pelvic organ prolapse. AIMS AND OBJECTIVES Compare the onset of motor and sensory block. Find out the duration of the sensory and motor blockade. Observe intraoperative hemodynamic changes and assess post-operative analgesia requirements in 24 hour. Duration of analgesia assessed by requirement of rst rescue analgesic. Observe any untoward incident during intraoperative and post-operative period and managed accordingly MATERIALS AND METHODS Study Area: Department of Anesthesiology & critical care, DARBHANGAMEDICALCOLLEGE AND HOSPITAL. Study Population: Adult patients (30- 65 years) undergoing elective abdominal hysterectomy with regional anaesthesia were included for this study. Study Period:January 2019 to March 2020 Sample Design: Subjects were divided into two groups (n=35) equal in numbers and they sampled as per computerized randomization chart. These patients were divided into two groups, group B (with epidural 0.5% bupivacaine and 100g fentanyl) and group R (with epidural 0.75% ropivavaine and 100g fentanyl). Study Design: Prospective, open, randomized, controlled study. RESULTS: In Our study showed that 3.38kg/m2 and 24.86 3.60 kg/m2in group B and R respectively. The duration of surgery was 100.86 9.35minutes and 98.86 8.32 minutes and the duration of stay, was4.86 0.81days and 4.60 0.914 days in group B and group R respectively. Now with comparison of both groups, time to onset of sensory block (uptoT6) has signicant variation. But the other parameters namely, time to onset of motor block, two segment regression or duration of sensory block, rescue analgesia timing and complete motor recovery time were comparable and not signicant statistically in both groups. SUMMARY & CONCLUSIONS To conclude that in the present study using 0.5% bupivacaine with fentanyl and 0.75% ropivacaine with fentanyl epidurally, ropivacaine produced an earlier onset but similar duration of sensory block. The onset, quality and duration of motor block werecomparable in both the groups. It is important that new local anaesthetics with lower cardiotoxic property are adopted to ensure that regional techniques using large amounts of local anaesthetics remain safe with minimal complications. The recovery prole of ropivacaine may be useful where prompt mobilization is require

Introduction: Acute coronary syndrome remains as one of the most important causes for morbidity and mortality in developed countries. Therefore, evidence-based management strategy is required to offset the loss of health during an acute coronary syndrome. An effective approach includes both medical and surgical methods. This study was conducted to evaluate the medical method of management. Objective: To study blood pressure and heart rate variability after administration of Ivabradine or metoprolol in cases with acute coronary syndrome. Materials and methods: The study was a Prospective single center observational study conducted in patients attending Cardiology Intensive Care Unit in Nayyar Heart and Superspecialty Hospital, a tertiary care centre located in an urban area. All patients with Acute coronary syndrome admitted to the emergency or cardiac care unit were analysed with ECG as a preliminary diagnostic test and confirmed with troponin markers. They were either given Ivabradine or Metoprolol. Baseline evaluation and follow up was done and necessary data was collected and analysed.   Results: 100 patients were included in the study out of which 50 were given Metoprolol (Group A) and 50 were given Ivabradine (Group B). Themean age of studied cases was found to be 66.54 years in group A and 68.69 years in group B. It was observed that there was a fall in heart rate by 26.8 beats per minute with beta blocker and 24.4 beats per minute with Ivabradine. In case of blood pressure measurement, in patients with beta blocker administration, there was a fall of 25 mm Hg in systolic blood pressure and 17 mm Hg in diastolic blood pressure However, with Ivabradine there was only a fall of 8mm Hg in systolic Blood pressure and 6 mm Hg in diastolic blood pressure. Conclusion: Although Metoprolol is the drug of choice to decrease heart rate and blood pressure in acute coronary syndrome, Ivabradine is being increasingly used in cases where beta blockers are contraindicated as it has similar efficacy in lowering heart rate without compromising contractility of cardiac muscle, thereby maintaining LVEF and blood pressure. Keywords: Acute coronary syndrome, Beta Blockers, Metoprolol, Ivabradine.

BackgroundThis randomized trial compared perineural dexamethasone (5 mg) and dexmedetomidine (100 µg) for ultrasound-guided infraclavicular brachial plexus block. We hypothesized that both adjuvants would result in similar durations of motor block and therefore designed the study as an equivalence trial (equivalence margin=3.0 hours).MethodsOne hundred and twenty patients undergoing upper limb surgery with ultrasound-guided infraclavicular block (using 35 mL of lidocaine 1%–bupivacaine 0.25% with epinephrine 5 µg/mL) were randomly allocated to receive perineural dexamethasone (5 mg) or dexmedetomidine (100 µg). Patients and operators were blinded to the nature of the perineural adjuvant. After the performance of the block, a blinded observer assessed the success rate (defined as a minimal sensorimotor composite score of 14 out of 16 points at 30 min) as well as the incidence of surgical anesthesia (defined as the ability to complete surgery without local infiltration, supplemental blocks, intravenous opioids, or general anesthesia). Heart rate and blood pressure were recorded before the block as well as during the first 2 hours after its performance. Furthermore, the level of sedation (using the Ramsay Sedation Scale) was recorded in the postanesthesia care unit. Postoperatively, the blinded observer contacted patients with successful blocks to inquire about the duration of motor block, sensory block, and postoperative analgesia.ResultsNo intergroup differences were observed in terms of success rate and surgical anesthesia. Compared with dexmedetomidine, dexamethasone provided longer durations of motor block (17.4 (4.0) vs 14.3 (3.0) hours; p<0.001; 95% CI 1.7 to 4.5), sensory block (19.0 (4.0) vs 15.0 (3.2) hours; p<0.001; 95% CI 2.6 to 5.4), and analgesia (22.2 (3.6) vs 16.9 (3.9) hours; p<0.001; 95% CI 3.7 to 6.9). Dexmedetomidine resulted in lower heart rate and blood pressure after the performance of the block, as well as an increased level of sedation postoperatively.ConclusionCompared with dexmedetomidine (100 µg), dexamethasone (5 mg) results in longer sensorimotor block and analgesic durations, as well as a decreased level of patient sedation. Further studies are required to compare dexamethasone and dexmedetomidine using different doses, local anesthetic agents, and approaches to the brachial plexus.Trial registration numberNCT03610893

Introduction: Neuraxial opioids are widely used as adjuvants to local anaesthetic as they improve quality and duration of block. Neuraxial opioids like Butorphanol and Fentanyl allow prolonged analgesia in the postoperative period and faster recovery from spinal anaesthesia. Aim: To compare the safety and efficacy of Butorphanol and Fentanyl combined with bupivacaine for spinal anaesthesia in infraumbilical surgeries. Materials and Methods: The present study was a randomised controlled trial in which 110, ASA I and II patients of either sex who underwent elective infraumbilical surgeries under spinal anaesthesia were selected. Patients were allocated randomly into two groups A (n=55) and B (n=55). Group A (F) received intrathecal 0.5% hyperbaric bupivacaine 12.5 mg (3 mL) with fentanyl 25 microgram (0.5 mL) to make it total 3.5 mL. Group B (B) received intrathecal 0.5% hyperbaric bupivacaine 12.5 mg (3 mL) with butorphanol 250 microgram (0.25 mL) and Normal Saline (NS) 0.25 mL to make it total 3.5 mL. Heart Rate (HR), Systolic and Diastolic Blood Pressure (SBP, DBP), two segment regression time of sensory block, motor block were assessed at preset intervals. Chi-square test or Fischer’s-exact test were used and a p-value ≤0.05 was considered as statistically significant. Results: Mean of two segment sensory regression time of Group A was 41.94±1.73 minutes and Group B was 50.56±4.43 minutes (p<0.0001). Time to onset of motor block in Group A was 5.28±.32 minutes and Group B was 5.27±.32 minutes (p=0.96). Mean duration of motor block in Group A was 81.23±4.87 minutes and Group B was 109.83±2.61 minutes (p<0.0001). Time to rescue analgesic was 289.27±7.37 minutes in Group A and 378.41±10.25 minutes in Group B (p<0.0001). HR, SBP and DBP were comparable among the groups. Conclusion: Intrathecal bupivacaine-butorphanol mixture was clinically better as it provided longer duration of analgesia with lesser incidences of pruritus and nausea/vomiting compared to intrathecal fentanyl-bupivacaine mixture.

Background: Regional anesthesia techniques for gynecological procedures are on increasing trends due to their advantage of postoperative analgesia owing to intrathecal adjuvants. The present study was aimed to comparatively evaluate the clinical efficacy of clonidine with nalbuphine when co-administered intrathecally with 0.5% hyperbaric bupivacaine for Lower abdominal surgeries in Gynecology. Methods: With institutional ethics committee clearance No. 193MC/EC/2018, randomized, double blind study was conducted. After obtaining informed written consent total of 84 patients scheduled for lower abdominal surgeries were randomly allocated into two groups: Group A (n=42) - Inj.  3.5 ml Bupivacaine 0.5% + 0.2 ml Clonidine(30µg) intrathecally.  Group B (n=42) - Inj.3.5 ml Bupivacaine 0.5%+0.2 ml Nalbuphine(2mg) intrathecally. The characteristics of sensory and motor block, hemodynamic data, side effects were recorded. Results: The onset of sensory block was earlier in Group B than Group A (3.08±0.52 min vs 4.00±0.54 min, p<0.001 ). The onset of motor block was also earlier in Group B than Group A (7.78±0.80 min vs 8.80±0.95min, p<0.001). The time to first rescue analgesia in patients receiving intrathecal clonidine was significantly delayed than patients receiving intrathecal nalbuphine (284.95 ± 12.93 min vs 211.52 ± 15.92 min, p<0.001). Introperative hemodynamic changes were comparable and none of the patient suffered from respiratory depression except very little cases of shivering which are not significant. Conclusions: Intrathecal clonidine as adjuvant to bupivacaine provided was clinically more effective than nalbuphine for prolonging the duration of analgesia for gynecological procedures.
