Background and Objective: Fentanyl and clonidine as adjuvants are commonly mixed with 0.5% bupivacaine heavy, by intrathecal route, for prolonging both sensory and motor blockade as well as for enhancing postoperative analgesia in patients undergoing major abdominal or lower limb surgery. This study was undertaken to compare the intraoperative effects and postoperative analgesia of fentanyl and clonidine, used as adjuvant to intrathecal bupivacaine during knee arthroplasty. Methodology: This prospective, randomized study was conducted on 60 patients of ASA grade I or II, between 20 and 50 years of age divided into two groups of 30 each. The patients were given 3 ml of 0.5% hyperbaric bupivacaine with either 25 mcg of fentanyl (Group F) or 50 mcg of clonidine (Group C) intrathecally. The onset of sensory and motor block, the duration of blockade, hemodynamic parameters, sedation score, total postoperative analgesia time, and side effects if any were recorded. Results: Both the groups were statistically comparable for demographic data, onset of sensory and motor blockade, duration of blockade and hemodynamic parameters. However, the sedation score was more in clonidine group. The duration of analgesia was significantly prolonged in clonidine group when compared with fentanyl group. Conclusion: In comparison to fentanyl, addition of clonidine to intrathecal bupivacaine prolongs the duration of postoperative analgesia and cause a higher sedation score.

ABSTRACT Introduction This single-center, prospective, randomized, double-blind study compares the effect of intrathecal fentanylbupivacaine and tramadol-bupivacaine on the onset and duration of sensory and motor blockade, as well as postoperative analgesia in lower abdominal surgeries. Materials and methods Patients of either sex, aged 18 to 60 years, American Society of Anesthesiologists (ASA) grade I/II undergoing lower abdominal surgeries like appendicectomy, inguinal hernia repair surgery, and hydrocele surgery were administered either 2.5 mL of 0.5% bupivacaine + 0.5 mL (25 μg) of fentanyl citrate (group F) or 2.5 mL of 0.5% bupivacaine + 0.5 mL (25 mg) of tramadol (group T) intrathecally. Monitoring of the vital parameters, onset and duration of sensory and motor block, duration of postoperative analgesia, visual analog scale (VAS) score, sedation score, and any adverse drug reactions was done at predetermined intervals. Results Sixty patients were randomized to the group F (n = 30) and group T (n = 30). The duration of sensory blockade was significantly prolonged in group F (314.66 ± 49.25 minutes) as compared to group T (261.66 ± 27.92 minutes). Similarly, duration of motor blockade was longer in group F (263.66 ± 40.97 minutes) compared to group T (214.66 ± 26.61 minutes). The total duration of analgesia was significantly prolonged (p < 0.001) in group F (412 ± 97.888 minutes) compared to group T (301 ± 38.75 minutes). Hemodynamic parameters, such as pulse, systolic blood pressure, diastolic blood pressure and oxygen saturation were comparable in both the groups. Visual analog scores were significantly lower in the group F patients as compared to the group T patients. The group F patients had got significantly higher sedation scores as compared to Group T patients. Discussion Fentanyl 25 μg, when added to 2.5 mL of 0.5% hyperbaric bupivacaine, confers prolonged duration of sensory and motor blockade than 25 mg tramadol added to 2.5 mL of 0.5% hyperbaric bupivacaine. The bupivacaine-fentanyl combination prolonged duration of sensory and motor blockade, improved analgesia, as manifested by lower pain scores, and prolonged duration of postoperative analgesia.

Background: In this double-blind, randomized study, the efficacy of tramadol, an atypical opioid, was tested versus lidocaine in excision of cutaneous lesions of the face. Methods: Eighty-eight patients were randomly assigned to receive either 2 mg/kg tramadol 2% plus adrenaline 1:200,000 (group T, n = 46) or 3 mg/kg lidocaine 2% plus adrenaline 1:200,000 (group L, n = 42) for excision of cutaneous lesions. Pain at the injection site, 2 and 20 minutes postinjection and 3, 6, and 12 hours postoperatively, was monitored on a 0 to 10 numerical rating scale (NRS). Irritation at the injection point and the duration of postoperative analgesia were also recorded. Results: There were no significant differences in demographic data, topography, size of the lesions removed, and operative time between the two groups. A tendency toward lower injection NRS pain scores was observed in group L compared to group T (p = .064). No statistically significant differences between the two groups were found at 2 and 20 minutes postinjection (p = .741 and p = .142, respectively); however, pain scores were significantly higher in group L at 3, 6, and 12 hours postoperatively (all p < .001). Erythema at the injection site was observed in nine group T and two group L patients (p = .076). No postoperative analgesics were required in the tramadol group of patients, whereas acetaminophen with or without codeine was administered in all but five lidocaine group patients during the first 12 hours. Conclusion: Tramadol may be used as a reliable local anesthetic agent, providing longer postoperative analgesia compared to lidocaine; however, it bears a higher incidence of irritation at the injection site.

Effective Analgesia

Background: Dexmedetomidine and midazolam both modulate spinal analgesia by different mechanisms, and yet, no human studies are available to compare them for postoperative analgesia after neuraxial administration. Objectives: We investigated the addition of dexmedetomidine or midazolam to intrathecal bupivacaine on the duration of effective analgesia and clinical safety profile. Study Design: Prospective, randomized, double blind, placebo controlled study. Setting: University teaching hospital. Methods: The study cohort included a consecutive and prospective series of patients, referred for endourological procedures. The patients were randomly allocated into 3 groups (20 patients each) to receive intrathecally 3 mL of 0.5% hyperbaric bupivacaine in combination with 5 mcg of dexmedetomidine (dexmedetomidine group), 1 mg of midazolam (midazolam group) or 0.5 mL of 0.9% saline (control group). The groups were compared to the regression time of sensory block, duration of effective analgesia (defined as the time interval between administration of intrathecal drug to the time of first analgesic request or a numeric rating scale ≥ 4.0), sedation score, and side effects in the first 24 hours. Statistics: One way-ANOVA, Kruskal Wallis test, and Chi-square test (χ2), significance level: P < 0.05. Results: The duration of effective analgesia (time to first analgesic request) was significantly prolonged in the dexmedetomidine group (286 ± 64 minutes, P < 0.01) when compared with midazolam group (236.9 ± 64.9 minutes) and the control group (212.7 ± 70.2 minutes). Pairwise comparisons among the 3 groups with Bonferroni adjustment revealed that patients from the dexmedetomidine group were more sedated in comparison to the midazolam and control groups at the end of the first 15 minutes after intrathecal injection [χ2 (2) = 7.157, P = 0.028], with a mean rank sedation score of 35.58 for dexmedetomidine, 25.00 for midazolam, and 30.93 for control. No significant differences in the side effects were observed during the study period. Midazolam did not lengthen the time of the two segment sensory regression or the time to first request analgesia. Limitation: The study cannot be extrapolated to muscle cutting surgeries under spinal anaesthesia. Conclusions: The addition of dexmedetomidine (5 mcg) to 3 mL of intrathecal hyperbaric bupivacaine (0.5%) significantly prolongs the duration of effective analgesia in comparison to 1 mg midazolam or placebo (0.9% normal saline) with a comparable incidences of side effects.

Background: Objective of the study was to identify the efficacy of midazolam as an adjuvant to intrathecal hyperbaric bupivacaine 0.5%, a prospective, randomized, double blind study was conducted to compare the onset, duration of sensory and motor block, postoperative analgesia, hemodynamic changes and complications.Methods: Sixty patients, ASA I/II, Age 18-60 year, scheduled for infraumbilical surgeries, were randomly allocated to group BNS(n=30) to receive intrathecally 2.5 ml of 0.5% hyperbaric bupivacaine with 0.4 ml normal saline; and group BM (n=30) to receive 2.5 ml of 0.5% hyperbaric bupivacaine +2 mg preservative free midazolam 0.4 ml (5mg/ml). We observed onset, duration and regression of sensory and motor block, degree of sedation and pain scores, hemodynamic changes and adverse effects. (PS) version 3.0.0.34 was used for power and sample size calculation. Statistical analysis was performed using Microsoft (MS) office excel software with the student’s t-test and chi-square test (P=0.05)Results: Highest level of sensory blockade (p<.05), motor block duration (179.67±14.94 vs 151.83±10.96 min), sensory block duration (222±16.5 vs 174±12.53 min) and time to first requirement of i.v. analgesia were significantly higher in group BM. Postoperative VAS score was significantly less in group BM. Both groups were comparable in demographic data and hemodynamic changes.Conclusions: Intrathecal 2 mg midazolam found as an attractive adjuvant to 0.5% hyperbaric bupivacaine in spinal anesthesia in infraumbilical surgeries by producing significantly longer duration of motor and sensory block, good quality of intraoperative and postoperative analgesia with less incidence of nausea vomiting as compared to bupivacaine alone.

Caudal Epidural

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.

Introduction: Various adjuvants have been added to bupivacaine to shorten the onset of block and prolong the duration of block. Present study was undertaken to compare the efficacy of intrathecal clonidine or buprenorphine with bupivacaine in lower abdominal surgeries. Methods: 90 ASA I and II patients undergoing lower abdominal surgeries were randomly allocated into three groups(n=30). Group A received 3ml of 0.5% hyperbaric bupivacaine with 1ml normal saline, Group B received 3ml of 0.5% hyperbaric bupivacaine with 60 mcg buprenorphine(1:5 dilution) and Group C received 3ml of 0.5% hyperbaric bupivacaine with 30mcg clonidine(1:5 dilution) respectively (Total volume 4ml). Onset time and duration of sensory and motor block, duration of analgesia, hemodynamics, VAS score, sedation score and side effect were compared. Results: The duration of analgesia was significantly longest in Group C (354.50±38.48min), followed by Group B (277.10±25.47min) and Group A(131.50±20.15min) (p<0.001) Conclusion: Clonidine(30mcg) and buprenorphine(60mcg) when used as adjuvants to 0.5% hyperbaric bupivacaine intrathecally produces significantly longer duration and better quality of postoperative analgesia than bupivacaine alone. On comparing the two drugs, Clonidine appears to be superior in terms of postoperative analgesia. Keywords: clonidine, buprenorphine, intrathecal, postoperative analgesia.

Background: Intrathecal ropivacaine is now routinely used for lower limb surgery. Adjuvants e.g. fentanyl, dexmedetomidine or morphine etc. are commonly used to prolong the intraoperative anesthesia or postoperative analgesia. The available literature lacks information on use of butorphanol and nalbuphine as adjuvants with 0.75% isobaric ropivacaine. We aimed to compare nalbuphine and butorphanol as adjuvant with isobaric ropivacaine in lower limb orthopedic surgeries. Methodology: After institutional ethical committee approval and informed written consent, a total of 108 patients of ages between 18 to 65 y, of either sex, American Society of Anesthesiologists (ASA) grade ӏ & ӏӏ, scheduled for elective lower limb orthopedic surgeries, were enrolled and  randomly allocated into two groups: Group RN; to receive isobaric ropivacaine (0.75%, 7.5 mg/ml) 2.5 ml plus nalbuphine 500 µg (0.5 ml), and Group RB; to receive isobaric ropivacaine 2.5 ml plus butorphanol 100 µg (0.5 ml) intrathecally. Primary outcome measure was the duration of sensory‑motor blockade from the time of intrathecal drug administration. Statistical analysis was performed by using t-test and chi-square test as applicable. A p < 0.05 was considered as significant. Results: Duration of sensory (p < 0.001) and motor blockade (p = 0.02) was significantly prolonged in nalbuphine group than butorphanol group. Onset of blockade was earlier in nalbuphine group. Duration of motor block and sensory analgesia was prolonged in group RN (p < 0.001). Perioperative hemodynamic parameters and the observed side effects including bradycardia, hypotension, nausea and vomiting, sedation and shivering were comparable between the two groups (p = 0.77). Conclusion: Intrathecal nalbuphine produces prolonged motor blockade as well as postoperative analgesia than intrathecal butorphanol when used as adjuvants to isobaric 0.75% ropivacaine.

Abstract The use of opioids in intrathecal or epidural anesthesia has become popular to optimize postoperative analgesia. However, opioid-induced side effects, such as respiratory depression, nausea, vomiting, urinary retention and pruritus, limit their use. Several investigations have shown that intrathecal or epidural administration of opioids produces a dose dependent modulation of spinal nociceptive processing in animals and humans and is not associated with sedation. Aim of Study The purpose of this study was to assess the spinally mediated analgesic effects postoperativally of intrathecal Nalbuphine plus bupivacaine after lower abdominal surgeries in comparison to intrathecal bupivacaine plus fentanyl Patients & Methods : 60 patients came to Ain-shams Hospital for lower abdominal surgeries, They were randomly allocated into two equal groups (30 patients each) group F and group N. Group F : Bupivacaine-Fentanyl Patients received an intrathecal injection of 3 ml of 0.5% heavy (hyperbaric) bupivacaine plus 0.5 ml (25 µg) fentanyl. Group N: Bupivacaine-Nalbuphin Patients received an intrathecal injection of 3 ml of 0.5% heavy (hyperbaric) bupivacaine plus 0.5 ml (0.5 mg) Nalbuphine. All patients were assessed and monitored for: Hemodynamics: ECG for heart rate, and non-invasive arterial pressure, respiratory rate and arterial oxygen saturation, onset of sensory block, onset of motor block, duration of analgesia & 1st rescue analgesia, duration of motor block, adverse effects as: hypotension, bradycardia, respiratory depression, pruritus, shivering, nausea and vomiting were recorded. Results & Conclusion Addition of a small dose of nalbuphine or fentanyl to bupivacaine in spinal anesthesia moderately prolonged the time of postoperative analgesia the duration of postoperative analgesia is nearly the same in nalbuphine group & the fentanyl group. There is more rapid onset of motor block in fentanyl group than in nalbuphine group but with no difference in sensory or motor block regression. No respiratory depression or degree of sedation occurs in both groups. Hemodynamic stability & side effects incidence are the same in both groups

Background: Spinal anesthesia is commonly used for caesarian section for its reliability and ease of administration. However, it is limited by fixed duration of anesthesia, hypotension and lesser control of block height. The combination of reduced dose of local anesthetic agent with intrathecal opioid makes it possible to achieve adequate spinal anesthesia with minimum hypotension and prolonged postoperative analgesia. The study aims to monitor the effect of intrathecal fentanyl and bupivacaine on reduction of higher blocks and simultaneously improving the quality and avoiding higher doses of local anesthesia agents. Methods: Forty patients scheduled for elective caesarian section were divided in to two groups of twenty each. Group I patients received Bupivacaine 12.5 mg (0.5%) for spinal anesthesia and group II patients received combination of Bupivacaine 8.5 mg (0.5%) with fentanyl 25 mcg. Patients were observed for hypotension, bradycardia, nausea, pruritus, quality of surgical anesthesia and duration of postoperative analgesia. Results: All the patients had adequate surgical anesthesia for the procedure and in no patient conversion to general anesthesia was required. Peak sensory level was higher (T2-T3 vs T4-T6) and motor block was more intense in the regular dose bupivacaine group of patients. More patients in bupivacaine only group developed hypotension and the requirement of vasopressors was significantly higher than the low dose bupivacaine with fentanyl group. Also the Visual analogue scale score for pain was less in the bupivacaine-fentanyl group, who received less postoperative analgesics for first twelve hours. Conclusions:  We conclude that combination of low dose bupivacaine (8.5mg) with fentanyl provides adequate surgical anesthesia for caesarian section and with low incidence of hypotension and nausea. Also, addition of fentanyl helps in prolongation of postoperative analgesia. JMS 2017;20(2):62-68
