Abstract
Various studies have described the use of Dexmedetomidine with local anaesthetic drugs in caudal blocks for the management of postoperative pain in children. This study was designed to determine the analgesic effect of caudal Dexmedetomidine with Ropivacaine in paediatric genitourinary infraumbilical surgeries. Postoperative analgesic effects of caudal Ropivacaine with or without Dexmedetomidine in paediatric genitourinary infraumbilical were evaluated. This study was a prospective, interventional, comparative study conducted after ethical approval from the institute. Informed expressed consent was taken from each patient's guardians. The sample size was calculated to be 31 in each group. The two groups were randomly assigned and the intervention involved caudal epidural injection with either Ropivacaine combined with Dexmedetomidine or Ropivacaine with Normal Saline. Children receiving Ropivacaine with Dexmedetomidine had a significantly prolonged duration of analgesia compared to those receiving Ropivacaine alone (840.35 ± 149.97 vs. 412.90 ± 93.46 min, P < 0.001). Postoperative rFLACC scores were consistently lower in the Dexmedetomidine group, indicating better pain control (P < 0.05 at 6, 12, and 24 h). Total analgesic consumption was lower in the Dexmedetomidine group (500.67 ± 212.92 vs. 741.75 ± 268.06 mg, P < 0.01). No significant differences in adverse effects were observed between the groups. The addition of Dexmedetomidine to Ropivacaine in caudal epidural significantly prolongs analgesia, improves pain control, and reduces analgesic consumption in paediatric genitourinary infraumbilical surgeries.

Abstract
BACKGROUND Morphine is commonly used in pediatric caudal blocks. We compared the analgesic efficacy and effect on cortisol levels of intrathecal morphine and bupivacaine with caudal morphine and bupivacaine in children undergoing lower abdominal surgeries. METHODS Forty children undergoing lower abdominal surgeries were randomized to receive 4 μg/kg of intrathecal morphine and 0.5% hyperbaric bupivacaine (n = 20), or caudal morphine 40 μg/kg and 0.25% bupivacaine (n = 20). Postoperative analgesia was provided with intravenous (IV) paracetamol (PCM). The primary outcome was time to reach Face, Legs, Activity, Cry, and Consolability (FLACC) score ≥4 postoperatively. Secondary outcomes were perioperative serum cortisol levels, analgesic requirement, and parent satisfaction. RESULTS Since seventy 5% of patients receiving intrathecal morphine and bupivacaine did not reach a FLACC score ≥4 within 24 hours, the primary outcome was presented as the Kaplan-Meier curve. The probability of FLACC score <4 was significantly higher with intrathecal morphine and bupivacaine than with caudal morphine and bupivacaine (P < .001). The unadjusted and adjusted (for gender) hazard ratio (95% confidence interval [CI]) of occurrence of pain (FLACC score ≥4) was 0.07 (0.03-0.15, P < .001) and 0.06 (0.03-0.14, P < .001), respectively. The difference in means (95% CI) of cortisol levels between caudal morphine (with bupivacaine) and intrathecal morphine (with bupivacaine) groups were after intubation -0.667 (-4.99 to 3.65, P = .76), at 2 hours intraoperatively 7.88 (3.55-12.2, P < .001), 6 hours postoperatively 16.8 (12.5-21.1, P < .001), and 24 hours postoperatively 15.4 (11.1-19.7, P < .001) μg/dL. Intraoperatively, rescue fentanyl was required by 60% of patients on caudal morphine and bupivacaine against 20% of patients receiving intrathecal morphine and bupivacaine (absolute risk-reduction [95% CI] of 40% [12%-68%]; P = .010). Postoperative rescue fentanyl was required in 45% of patients on caudal morphine and bupivacaine and 5% of patients on intrathecal morphine and bupivacaine. All (100%) patients on caudal morphine and bupivacaine required postoperative PCM against 6 (30%) patients on intrathecal morphine and bupivacaine (absolute risk-reduction [95% CI] of 70% [50%-90%]; P < .001).The median (interquartile range [IQR]) parent satisfaction score for patients on caudal morphine (with bupivacaine) and intrathecal morphine (with bupivacaine) was 0(0-0) and 2(2-2) at 12 hours postoperatively (P < .001) and 0(0-1) and 2(1.5-2) at 24 hours postoperatively (P < .001). One patient in each group developed nausea and vomiting, and 1 patient in the intrathecal group developed pruritus. There was no incidence of respiratory depression. CONCLUSIONS Intrathecal morphine and bupivacaine results in longer duration of analgesia, lower analgesic consumption, prevents surgical-stress-related elevation of serum cortisol, and improves parent satisfaction compared to caudal morphine with bupivacaine in children undergoing lower abdominal surgeries.

Abstract
Various adjuvants are added to local anesthetics in caudal block to improve analgesia. The comparative analgesic effectiveness and relative rankings of these adjuvants are unknown. This network meta-analysis (NMA) sought to evaluate the comparative analgesic efficacy and relative ranking of caudal adjuvants added to local anesthetics (versus local anesthetics alone) in pediatric infra-umbilical surgery. We searched the United States National Library of Medicine database (MEDLINE), PubMed, and Excerpta Medica database (Embase) for randomized controlled trials (RCTs) comparing caudal adjuvants (clonidine, dexmedetomidine, ketamine, magnesium, morphine, fentanyl, tramadol, dexamethasone, and neostigmine) among themselves, or to no adjuvant (control). We performed a frequentist NMA and employed Cochrane's 'Risk of Bias' tool to evaluate study quality. We chose the duration of analgesia (defined as 'the time from caudal injection to the time of rescue analgesia') as our primary outcome. We also assessed the number of analgesic dose administrations and total dose of acetaminophen within 24 h. The duration of analgesia [87 randomized control trials (RCTs), 5285 patients] was most prolonged by neostigmine [mean difference: 513 min, (95% confidence interval, CI: 402, 625)]. Dexmedetomidine reduced the frequency of analgesic dose administrations within 24 h [29 RCTs, 1765 patients; -1.2 dose (95% CI: -1.6, -0.9)] and the total dose of acetaminophen within 24 h [18 RCTs, 1156 patients; -350 mg (95% CI: -467, -232)] the most. Among caudal adjuvants, neostigmine (moderate certainty), tramadol (low certainty), and dexmedetomidine (low certainty) prolonged the duration of analgesia the most. Dexmedetomidine also reduced the analgesic frequency and consumption more than other caudal adjuvants (moderate certainty).

Abstract
Background: Clonidine is an anesthetic with favorable efficacy and safety profiles for caudal epidural block, but comparisons with other adjuvants need to be confirmed in pediatric patients. Aim: To investigate the effects of clonidine as an adjuvant in caudal epidural block to improve the intraoperative and postoperative analgesia in pediatric surgery. Methods: PubMed, Embase, and the Cochrane Library were searched for available papers published up to February 2021. The outcomes were pain score, duration of analgesia, complications, and number of analgesic requirements. The meta-analysis was performed using random-effects models. Results: Fifteen randomized controlled trials (RCTs) were included. There were no differences between clonidine and the control drug regarding the duration of analgesia (SMD = -0.71, 95%CI: -1.64, 0.23; I 2 = 95.5%, Pheterogeneity < 0.001), pain score (SMD = 0.35, 95%CI: -0.28, 0.98; I 2 = 80.8%, Pheterogeneity < 0.001), and requirement for additional analgesia (OR = 8.77, 95%CI: 0.70, 110.58, I 2 = 81.9%, Pheterogeneity = 0.004), but using clonidine resulted in fewer complications than the control drugs (OR = 0.33, 95%CI: 0.20, 0.54, I 2 = 21.8%, Pheterogeneity = 0.217). The sensitivity analysis showed that the results were robust. A publication bias was observed. Conclusion: Clonidine has the same efficacy as the other adjuvants for caudal epidural block for pediatric surgery but fewer complications. These results support clonidine as an adjuvant to local anesthetic, but additional studies should be conducted.

Abstract
Objective The aim of this systematic review and meta-analysis is to compare the outcomes of morphine vs. clonidine use as adjuvants in caudal anaesthesia. We are specifically focused on analgesic and side effect profiles. Methods We searched databases and trial registration sites and include here randomised controlled trials that compare the analgesic effects of caudal clonidine vs. morphine as adjuvants on postoperative pain. The risk ratio for evaluating pain scores, the need for rescue analgesia and all adverse effects were assessed. The i2 statistic was used to assess heterogeneity. We also assessed risk of bias with Cochrane’s Collaboration tool. The quality of evidence was assessed with Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Results Four randomised controlled trials (including 166 patients) that evaluated the use of clonidine vs. morphine as adjuvants in caudal block were included in this systematic review and meta-analysis. The pooled estimate for postoperative analgesia revealed no statistically significant differences between the clonidine group compared to morphine group (MD=2.90; 95% CI 4.05 to 9.85; i2 93%). Significantly less postoperative nausea and vomiting were reported among the patients that received clonidine vs. those that were treated with morphine (RR 0.57, 95% CI −0.36 to −0.90, i2 26%). There were no statistically significant differences between the two groups in assessments that included urinary retention, pain scores or need for rescue analgesia at 24 hours. Conclusion Clonidine is just as effective as morphine when used an adjuvant to local anaesthetic for caudal block, and has a more desirable side effect profile, particularly with respect to postoperative nausea and vomiting.

Abstract
BACKGROUND Ultrasound-guided quadratus lumborum block is a regional anesthetic technique which can provide perioperative analgesia for all age groups, including pediatric patients undergoing abdominal surgery. We hypothesized that the quadratus lumborum block would be as efficacious as a caudal block, the gold standard of pediatric lower abdominal regional anesthesia, in providing pain control after ureteral reimplantation but also have a longer duration. METHODS Forty-seven pediatric patients between the ages of 1 and 17 years undergoing bilateral ureteral reimplantation surgery via a low transverse incision were enrolled and randomized into the quadratus lumborum block and caudal block groups. All blocks were performed preoperatively under general anesthesia. We analyzed the following outcomes: the requirement for narcotic analgesics, pain score, episodes of emesis, and complications at 0, 4, 24, and 48 hours postoperatively. RESULTS The study included 44 patients after excluding three who were ineligible. The fentanyl requirement for postoperative rescue analgesia during the first 24 hours was significantly lower in the quadratus lumborum block group than in the caudal block group (median [interquartile range]: 0 [0-1] vs 3 [0-5], P = 0.016, 95% confidence intervals: -4 to 0) but not at 30 minutes, 4, or 48 hours. No significant difference was observed in the pain scores or the incidence of interventions to treat nausea and vomiting during the entire period. No postoperative complication was observed. CONCLUSION The quadratus lumborum block was more effective in reducing the postoperative opioid requirement for rescue analgesia during the initial 24 hours than caudal ropivacaine/morphine.

Abstract
BACKGROUND This meta-analysis was conducted to evaluate the analgesics effect and safety of dexmedetomidine (DEX) combined with bupivacaine (BU) on caudal epidural block. MATERIAL AND METHODS Published studies were identified using the PubMed, EMBASE, Web of Science, and the Cochrane Library from inception until October 2017. Relative risk (RR), the standardized mean difference (SMD), and the corresponding 95% confidence interval (CI) were calculated using the STATA 12.0. RESULTS Ten randomized controlled trials (RCTs) were selected for this meta-analysis, involving a total of 691 patients. There was a longer duration of postoperative analgesia in children receiving DEX (SMD=3.19, 95% CI: 2.16-4.22, P<0.001). Furthermore, there was a lower number of patients requiring rescue analgesics in the (BU) + (DEX) group (6 hours: RR=0.09, 95% CI: 0.05-0.17, P<0.001; 12 hours: RR=0.50, 95% CI: 0.32-0.79, P=0.003; 24 hours: RR=0.66, 95% CI: 0.51-0.85, P=0.002). Finally, the occurrence of adverse events, between BU and DEX + BU group, was not statistically significant (RR=0.96, 95% CI: 0.58-1.58, P>0.05). CONCLUSIONS DEX seems to be a promising adjuvant to BU increase duration of caudal analgesia without an increase in side effects in children. However, the result may be influenced by clinical heterogeneity. More large-scale, multicenter, approaching, double-blinded RCTs are required to confirm our results.

Abstract
Background Clonidine is a common adjunct to local anesthetics for pediatric neuraxial block; however, the pros and cons between clonidine and other adjuncts remain unclear. Thus, we performed this meta-analysis of randomized controlled trials to assess the efficacy and adverse effects between clonidine and other adjuncts added to local anesthetics. Materials and methods The systematic search, data extraction, critical appraisal, and pooled analysis were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Randomized controlled studies were searched in Cochrane (to present), Medline (1946 to present), Embase (1974 to present), and Biosis (1995 to present). Relative risks (RRs), standard mean difference (SMD), and associated CIs were calculated using RevMan statistical software to assess continuous and dichotomous data. Heterogeneity in studies was measured by forest plots and I2 values. Subgroup analysis was performed for continuous and dichotomous variables, while meta-regression was applied for continuous data with high I2 values. Results A total of 15 randomized controlled studies met the inclusion criteria. There was a longer duration of postoperative analgesia in the clonidine group than for other adjuncts (SMD=1.54, p=0.005, I2=96%). The number of patients requiring rescue analgesia was lower in the clonidine group without the addition of epinephrine (RR=0.55, p=0.0002, I2=0), while the RR for the comparison with epinephrine was significant (p=0.62, I2=95%). The duration of motor block was longer in the clonidine group (mean difference [MD]=1.06, p<0.00001, I2=0). The clonidine group also had a lower incidence of postoperative nausea and vomiting (PONV; RR=0.49, p<0.00001, I2=0). Postoperative bradycardia, hypotension, and urinary retention were not significantly different between clonidine and other adjuncts (p>0.05). Conclusion Clonidine, compared with other adjuncts, added to local anesthetics for neuraxial block, provides a longer duration of postoperative analgesia with lower incidence of PONV. However, the duration of motor block may also be prolonged by clonidine.

Abstract
BACKGROUND The use of intrathecal morphine may result in serious side effects in parturients undergoing cesarean delivery. Nalbuphine, is a mu receptor antagonist and a ĸappa receptor agonist. Combinations of opioid agonist and agonist antagonist can decrease the incidence of opioid related side effects. We aimed to investigate the effect of adding nalbuphine, to intrathecal morphine on postoperative nausea and vomiting and pruritus after a cesarean delivery. METHODS Eighty parturient undergoing elective cesarean delivery under spinal anesthesia were randomized into two similar groups. Group 1: received 10 mg of 0.5% hyperbaric bupivacaine with 0.2 mg morphine. Group 2: received as a group 1 plus 0.5 mg nalbuphine, with total volume 2.5 mL in both groups. Measurements: Data on the severity of nausea and vomiting were collected using a numerical rating scale and visual analogue scale was used to quantify pruritus. Onset and duration of sensory blockade, Visual Analog Scale for pain, the first time to ask for rescue analgesia and total rescue analgesic consumption were recorded. RESULTS Nausea and vomiting and pruritus severity scores and number of patients developed nausea and vomiting and pruritus were significantly lower (P<0.001) in group 2. Onset and duration of sensory block, time to first request for rescue analgesia, Visual Analog Scale for pain and paracetamol consumption showed no statistically differences between both groups (P>0.05). CONCLUSIONS We concluded that the addition of nalbuphine to intrathecal bupivacaine plus morphine significantly reduced the incidence and severity of postoperative nausea and vomiting and pruritus without affecting analgesic potency.

Abstract
Context: Caudal block is one of the most common regional anesthetic techniques employed in pediatric urogenital surgeries. Adjuvants play an important role to improve postoperative analgesia. Aims: The aim of this study was to evaluate the analgesic effect of dexamethasone when given systemically as against caudally as an adjuvant to caudal block. Subjects and Methods: In this randomized controlled study, sixty American Society of Anesthesiologists Physical Status I and II patients aged 3–6 years were randomly allocated into two groups of thirty each. Group D received caudal block with local anesthetic solution and 0.1 mg/kg injection dexamethasone. Group I received a caudal block with local anesthetic solution. They received intravenous injection dexamethasone 0.1 mg/kg after the block. Both the groups were compared for the duration of postoperative analgesia and analgesic requirement. Statistical Analysis Used: Statistical analysis was done with unpaired t-test and Chi-square test as was appropriate. Results: Group D showed a significant prolongation of postoperative analgesia (626.33 ± 59.39 min) as compared to Group I (194.67 ± 27.76 min). Similarly, requirement of analgesic was reduced on 1st postoperative day in group receiving caudal dexamethasone. Conclusions: Dexamethasone significantly prolongs the duration of postoperative analgesia of a caudal block when given caudally than when given intravenously.

Abstract
BACKGROUND The caudal epidural block is one of the most commonly used regional anesthetic techniques in children. Administration of morphine via caudal injection enables analgesia, even for upper abdominal surgery. The thoracic paravertebral block has also been successfully used to treat perioperative pain during upper abdominal procedures in pediatric patients. AIM In the current study, we compared the two regional techniques for upper abdominal surgery in infants to determine whether one of them was preferable to the other. METHODS Consecutive patients under 12 months of age who underwent upper abdominal surgery were retrospectively divided according to the chosen postoperative analgesia: Group C, caudal ropivacaine-morphine; Group P, paravertebral catheter. We analyzed the following outcomes: requirement for additional analgesics, pain scores, need for mechanical ventilation and oxygen dosage, postoperative blood pressure and heart rate, time to pass first stool, time until first full meal, and complications. RESULTS Twenty-one consecutive patients were included: 10 in Group C and 11 in Group P. Median age at surgery was 80 (47.5-270.0) and 84.5 (34.3-287.5) days, respectively. No difference was found between the two groups in requirement for additional analgesics at 24 h after surgery (median 1 in Group C vs 1 in Group P, P = 0.288, 95% CI: -2 to 1). BOPS pain scores were only lower in Group P when compared to Group C at 24 h after surgery (median 1 vs 2, P = 0.041, 95% CI: -2 to 0). None of the patients had perioperative complications. CONCLUSIONS In this small series, there was no significant difference between caudal ropivacaine-morphine and paravertebral catheter for postoperative care in infants undergoing upper abdominal surgery. Further prospective studies are needed to compare the efficacy and incidence of complications of caudal block and paravertebral catheter for postoperative analgesia.

Abstract
This review focuses on pharmacokinetics and pharmacodynamics of opioid and non-opioid analgesics in neonates and infants. The unique physiology of this population differs from that of adults and impacts drug handling. Morphine and remifentanil are described as examples of older versus recently developed opiates to compare and contrast pharmacokinetics and pharmacodynamics in infants. Exploration of genetics affecting both pharmacokinetics and pharmacodynamics of opiates is an area of active research, as is the investigation of a new class of mu-opiate-binding agents which seem selective for analgesic pathways while having less activity in pathways linked to side effects. The kinetics of acetaminophen and of ketorolac as examples of parenteral non-steroidal analgesics in infants are also discussed. The growth in regional anesthesia for peri-operative analgesia in infants can fill an important role minimizing intra-operative anesthetic exposure to opioids and transitioning to post-operative care. Use of multi-modal techniques is recommended to decrease undesirable opiate-related side effects in this vulnerable population.

Abstract
INTRODUCTION To test the efficacy and safety of caudal anesthesia (CA) supplemented by low dose morphine in children who undergo renal surgery. MATERIALS AND METHODS Forty patients aged 2 months-14 years were enrolled and randomly divided into two groups of 20 patients each: Group A (bupivacaine 0.2% with fentanyl); Group B (bupivacaine with morphine). The duration of surgery and hospitalization time were recorded. Postoperative pain score was measured by Face Legs Activity Cry Consolability scale and Wong-Baker Faces scale for those who are older. Overall use of rescue analgesics was calculated. RESULTS There was no statistical difference in the length of surgery, incidence of pruritus, postoperative nausea, vomiting and urinary retention between the two groups. However the postoperative opioid requirements were significantly higher in Group A 1.03 ± 0.9 mg/kg compared to Group B, in which only one patient required opioid therapy (p < 0.0001). Moreover the need for non-opioid rescue analgesic was higher in Group A, (36 ± 5.7 mg/kg of paracetamol) compared to morphine CA group there only 26 ± 3.6 mg/kg required during first 24 h of the postoperative period (p = 0.0312). The Face Legs Activity Cry Consolability pain score (1, 4, and 24 h after surgery) and Wong-Baker Faces scale were significantly higher in Group A. The hospitalization period was shorter in the CA morphine group, but the difference did not reach statistical significance. None developed hemodynamic instability or respiratory depression. CONCLUSIONS Our data show that CA supplemented with low dose morphine provides a longer duration of analgesia without significant side-effects in children undergoing renal surgery.

Abstract
Context: Postoperative pain management is becoming an integral part of anesthesia care. Various techniques of pediatric pain relief have been designed among which the most commonly practiced is caudal epidural block. Several adjuvants have been used to prolong the duration of caudal analgesia such as clonidine, neostigmine, ketamine, opioids, and ephedrine. We have designed the study using dexmedetomidine as an adjuvant to assess analgesic efficacy, duration of postoperative analgesia, hemodynamic stability, postoperative sedation, and any adverse effects in children. Aims: The aim is to study the effects of dexmedetomidine as an adjuvant to bupivacaine in caudal analgesia in pediatric patients posted for infraumbilical surgeries. Settings and Design: This is a randomized, double-blind study in which effect of dexmedetomidine is studied when added to bupivacaine in the caudal epidural block. The observations are made intraoperatively for hemodynamic stability and postoperatively for the duration of analgesia. Subjects and Methods: This study was conducted in 100 children of American Society of Anesthesiologists physical status I and II, aged 2–10 years, undergoing elective infraumbilical surgeries. They were divided into two groups as follows: Group A: (0.25%) bupivacaine 1 ml/kg + normal saline (NS) 1 ml. Group B: (0.25%) bupivacaine 1 ml/kg + 1 μg/kg dexmedetomidine in 1 ml NS. As this study was double-blind, patients were randomly assigned to receive either (bupivacaine + saline) or (bupivacaine + dexmedetomidine) in each group. The patients were observed for hemodynamic stability, respiratory depression, and postoperative pain using face, legs, activity, cry, consolability (FLACC) pain scale for 24 h postoperatively. Statistical Analysis Used: Unpaired Student's t-test. Results: The mean duration of effective analgesia in Group A patients was 4.33 ± 0.98 h versus 9.88 ± 0.90 h in Group B patients. Likewise, the difference in mean FLACC score of both the groups was also statistically significant, 7.21 ± 0.76 and 6.49 ± 1.72 in Group A and Group B, respectively. Conclusion: Dexmedetomidine as adjuvant to Bupivacaine increases duration of caudal analgesia and improves hemodynamic stability without an increase in adverse effects in children undergoing infraumbilical surgeries.

Abstract
Background and Aims: Caudal analgesia is one of the most popular regional blocks in paediatric patients undergoing infra-umbilical surgeries but with the drawback of short duration of action after single shot local anaesthetic injection. We evaluated whether caudal dexamethasone 0.1 mg/kg as an adjuvant to the ropivacaine improved analgesic efficacy after paediatric herniotomies. Methods: Totally 128 patients of 1–5 years age group, American Society of Anaesthesiologists physical status I and II undergoing elective inguinal herniotomy were randomly allocated to two groups in double-blind manner. Group A received 1 ml/kg of 0.2% ropivacaine caudally and Group B received 1 ml/kg of 0.2% ropivacaine, in which 0.1 mg/kg dexamethasone was added for caudal analgesia. Post operative pain by faces, legs, activity, cry and consolability tool score, rescue analgesic requirement and adverse effects were noted for 24 h. Results: Results were statistically analysed using Student's t-test. Pain scores measured at 1, 2, 4, and 6 h post-operative, were lower in Group B as compared to Group A. Mean duration of analgesia in Group A was 248.4 ± 54.1 min and in Group B was 478.046 ± 104.57 min with P = 0.001. Rescue analgesic requirement was more in Group A as compared to Group B. Adverse effects after surgery were comparable between the two groups. Conclusion: Caudal dexamethasone added to ropivacaine is a good alternative to prolong post-operative analgesia with less pain score compared to caudal ropivacaine alone.

Abstract
Background: Caudal block is a reliable regional analgesic technique for pediatric urogenital surgeries. Various adjuvants have been tried to enhance the duration of action of bupivicaine. Though clonidine is extensively used as an adjuvant in caudal anaesthesia, it can have troublesome adverse effects like bradycardia, hypotension and sedation. Lately dexamethasone has become popular as an adjuvant in paediatric caudals due to its safety profile. Aim: The aim of this study was to compare dexamethasone and clonidine coadministered with bupivicaine caudally in paediatric patients undergoing urogenital surgeries in terms of analgesia and adverse effects. Settings and Design: Prospective, double blinded randomised study. Subjects and Method: Sixty American Society of Anesthesiologists physical status I and II children, aged 1-6 years undergoing urogenital surgeries were allocated in 2 groups: Group I: 0.5 mL.kg−1 of 0.25% bupivicaine with dexamethasone 0.1 mg.kg−1 in 1 ml normal saline (NS) Group II: 0.5 mL.kg−1 of 0.25% bupivicaine with clonidine 1 μg.kg−1 diluted in 1 ml normal saline. The parameters studied included duration of analgesia, intraoperative and postoperative hemodynamics, sedation scores and incidence of adverse effects like wound dehiscence, bleeding, vomiting and respiratory depression. Statistical Analysis Used: Statistical analysis was carried out using Stata Version 10. After checking for the normality assumption, t-test for comparing means of two independent samples was used for comparing baseline continuous variables. P values <0.05 were considered significant. Results: Patients in Group II had longer duration of analgesia postoperatively. Patients in this group also had lower heart rate and more sedation scores. Conclusion: Our study shows that caudal dexamethasone is a good alternative to clonidine with more stable hemodynamics and lesser sedation scores in the immediate postoperative period. Both the drugs offer good analgesia postoperatively with the duration of analgesia more in clonidine.

Abstract
Background: Many adjuvants are used to increase the efficacy of epidural local anesthetics for postoperative analgesia. Aims: The aim was to compare the efficacy of epidural morphine (0.1 mg/kg) and clonidine (2 μg/kg) with bupivacaine (0.125%) for postoperative analgesia in abdominal surgeries. Settings and Design: Double-blind retrospective randomized study. Methodology: All the patients (n = 60) varying from age group belonging to American Society of Anesthesiologists I–II were randomly allocated to receive epidural analgesia Group A - Morphine (0.1 mg/kg). + Bupivacaine (0.125%) (n = 30), Group B - Clonidine (2 μ/kg) + Bupivacaine (0.125%) (n = 30). We monitored vitals and requirement of inhalational gases intra-operatively, pain by visual analogue score (VAS) and vitals postoperatively. We used rescue analgesics (injection diclofenac 1 mg/kg intravenous) when VAS score > 5. Postoperatively, various parameters were monitored for first 2 h at intervals of 30 min and at 4, 8, 12, 16, and 24 hourly intervals after giving 1st dose. Statistical Analysis Used: Continuous data are analyzed by Student's t-test (paired ‘t’-test for intragroup variations and unpaired ‘t’-test for intergroup variations). Chi-square test was used for categorical data. A P ≤ 0.05 was considered to be statistically significant. Results: Mean duration of analgesia was 8.35 ± 0.42 h in Group A (morphine) and 7.45 ± 0.44 h in Group B (clonidine). This difference was statistically significant (P < 0.001), indicating a prolongation of analgesia in group morphine. There was no need of rescue analgesia in any subjects. Group A patients were hemodynamically stable and required less inhalation agents intra-operatively compared to group B patients. Conclusions: Epidural morphine plus bupivacaine has a longer duration of analgesia and greater hemodynamic stability as compared to epidural clonidine plus bupivacaine for postoperative analgesia in abdominal surgeries.

Abstract
BACKGROUND Pediatric patients may be at an increased risk of adverse effects from various medications. Recently, there have been a number of serious adverse events, including several pediatric patients experiencing severe respiratory depression and death as a result of the use of codeine for pain control following tonsillectomy and adenoidectomy. OBJECTIVE To assess the safety of opioid agonists in pediatric patients undergoing operative procedures or have experienced trauma and to evaluate the risk of respiratory depression and death among this population. METHODS PubMed and Medline were searched to identify randomized controlled studies from 1994 to 2012 addressing postsurgery/trauma opioid use in pediatric patients. Relative risks and confidence intervals (CIs) were calculated using data available in clinical trials. RESULTS A total of 16 clinical trials were evaluated for this review. Randomized controlled trials included studies comparing opioids versus non-opioids for a variety of painful conditions. The relative risk of respiratory depression associated with opioid use in 1 trial was 1.63 (95% CI: 0.64-6.13). The remaining 15 trials reviewed described no significant difference in respiratory depression or adverse effects associated with treatment. No deaths were attributed to opioid use in any of these studies. CONCLUSION Opioid-associated respiratory depression was very rare and no deaths were reported in the reviewed studies. These findings under the well-defined conditions of controlled studies may not be the best means of determining overall opioid-associated side effects in pediatric patients.

Abstract
BACKGROUND One of the most commonly used regional anesthetic techniques in pediatric surgeries is the caudal epidural block. Its main disadvantage remains the short duration of action. Hence, different additives have been used. Dexmedetomidine is a potent as well as highly selective α2 adrenergic receptor agonist. The aim of this randomized, double-blinded, study was to compare the duration of postoperative analgesia of caudal dexmedetomidine versus morphine in combination with bupivacaine in pediatric patients undergoing lower abdominal or perineal surgery. PATIENTS AND METHODS A total of 50 pediatric patients 1-5 years old The American Society of Anesthesiologists status I, II scheduled for lower abdominal and perineal surgeries were included in the study. The patients were enrolled into 2 equal groups: Group A patients (n = 25) received dexmedetomidine with bupivacaine while Group B patients (n = 25) received morphine with bupivacaine. Patients were placed in a supine position then inhalational general anesthesia was induced, and laryngeal mask airway (LMA) was placed. Patients were then given caudal epidural analgesia. By the end of surgery reversal of muscle relaxation was done and the LMA was removed. Post-operatively, the sedation as well as pain score were observed and recorded. RESULTS The current study showed that minor complications were recorded in the post-anesthesia care unit; in addition, significantly longer periods of analgesia and sedation were detected in Group A. However, no significant differences in demographic data, as well as in the duration of surgery, and the time of emergence from anesthesia and patient condition during recovery were detected. CONCLUSION The present study suggested that use of dexmedetomidine, during single dose injection, as an additive to the local anesthetic bupivacaine in caudal epidural analgesia prolongs the duration of post-operative analgesia following lower abdominal as well as perineal surgery compared with caudal morphine with no side-effects on the vital signs. Postoperative side effects were seen with caudal morphine injection rather than with dexmedetomidine.

Abstract
BACKGROUND Epidural administration of dexamethasone might reduce postoperative pain in adults. We evaluated whether a caudal block of 0.1 mg kg(-1) dexamethasone combined with ropivacaine improves analgesic efficacy in children undergoing day-case orchiopexy. METHODS This randomized, double-blind study included 80 children aged 6 months to 5 yr who underwent day-case, unilateral orchiopexy. Patients received either 1.5 ml kg(-1) of 0.15% ropivacaine (Group C) or 1.5 ml kg(-1) of 0.15% ropivacaine in which dexamethasone of 0.1 mg kg(-1) was mixed (Group D) for caudal analgesia. Postoperative pain scores, rescue analgesic consumption, and side-effects were evaluated 48 h after operation. RESULTS Postoperative pain scores at 6 and 24 h post-surgery were significantly lower in Group D than in Group C. Furthermore, the number of subjects who remained pain free up to 48 h after operation was significantly greater in Group D [19 of 38 (50%)] than in Group C [four of 37 (10.8%); P<0.001]. The number of subjects who received oral analgesic was significantly lower in Group D [11 of 38 (28.9%)] than in Group C [20 of 37 (54.1%); P=0.027]. Time to first oral analgesic administration after surgery was also significantly longer in Group D than in Group C (P=0.014). Adverse events after surgery including vomiting, fever, wound infection, and wound dehiscence were comparable between the two groups. CONCLUSIONS The addition of dexamethasone 0.1 mg kg(-1) to ropivacaine for caudal block can significantly improve analgesic efficacy in children undergoing orchiopexy. Clinical trial registration NCT01604915.

Abstract
BACKGROUND AND OBJECTIVES Dexmedetomidine (D) can prolong the duration of local anesthetics, but the effect of caudal dexmedetomidine on the potency of levobupivacaine (L) for caudal block has not been investigated. This study was designed to determine the effect of caudal dexmedetomidine on levobupivacaine for caudal block in pediatric patients. METHODS Eighty-nine children scheduled for elective inguinal hernia repair or hydrocele were randomly assigned to one of the three groups: Group L (caudal levobupivacaine), Group LD1 (levobupivacaine plus 1 μg·kg(-1) dexmedetomidine), or Group LD2 (levobupivacaine plus 2 μg·kg(-1) dexmedetomidine). The primary endpoint was the minimum local anesthetic concentration (MLAC), which was determined using the Dixon up-and-down method. The secondary endpoints were the duration of analgesia and sedation. RESULTS The MLAC values (sd) of caudal levobupivacaine were 0.103 (0.01)%, 0.068 (0.02)%, and 0.055 (0.03)% in Groups L, LD1, and LD2, respectively. The values of EC50 and EC95 (95% CI) of caudal levobupivacaine from logistic regression analysis were 0.094 (0.083-0.105)% and 0.129 (0.1-0.159)%, 0.058 (0.044-0.072)% and 0.106 (0.067-0.144)%, and 0.046 (0.033-0.059)% and 0.091 (0.055-0.127)% in Groups L, LD1, and LD2, respectively. The mean durations of analgesia in the postoperative period were 141, 378, and 412 min in Groups L, LD1, and LD2, respectively (L vs LD1 or LD2, P < 0.001). The mean durations of sedation in both Groups LD1 and LD2 also were significantly prolonged, compared with Group L (P < 0.01). CONCLUSIONS Caudal dexmedetomidine reduces the MLAC values of levobupivacaine and improves postoperative analgesia in children without any neurological side effects.

Abstract
This paper is the thirty-fourth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2011 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior (Section 2), and the roles of these opioid peptides and receptors in pain and analgesia (Section 3); stress and social status (Section 4); tolerance and dependence (Section 5); learning and memory (Section 6); eating and drinking (Section 7); alcohol and drugs of abuse (Section 8); sexual activity and hormones, pregnancy, development and endocrinology (Section 9); mental illness and mood (Section 10); seizures and neurologic disorders (Section 11); electrical-related activity and neurophysiology (Section 12); general activity and locomotion (Section 13); gastrointestinal, renal and hepatic functions (Section 14); cardiovascular responses (Section 15); respiration (Section 16); and immunological responses (Section 17).

Abstract
Neuraxial drugs provide robust pain control, have the potential to improve outcomes, and are an important component of the perioperative care of children. Opioids or clonidine improves analgesia when added to perioperative epidural infusions; analgesia is significantly prolonged by the addition of clonidine, ketamine, neostigmine, or tramadol to single-shot caudal injections of local anesthetic; and neonatal intrathecal anesthesia/analgesia is increasing in some centers. However, it is difficult to determine the relative risk-benefit of different techniques and drugs without detailed and sensitive data related to analgesia requirements, side effects, and follow-up. Current data related to benefits and complications in neonates and infants are summarized, but variability in current neuraxial drug use reflects the relative lack of high-quality evidence. Recent preclinical reports of adverse effects of general anesthetics on the developing brain have increased awareness of the potential benefit of neuraxial anesthesia/analgesia to avoid or reduce general anesthetic dose requirements. However, the developing spinal cord is also vulnerable to drug-related toxicity, and although there are well-established preclinical models and criteria for assessing spinal cord toxicity in adult animals, until recently there had been no systematic evaluation during early life. Therefore, in the second half of this review, we present preclinical data evaluating age-dependent changes in the pharmacodynamic response to different spinal analgesics, and recent studies evaluating spinal toxicity in specific developmental models. Finally, we advocate use of neuraxial drugs with the widest demonstrable safety margin and suggest minimum standards for preclinical evaluation before adoption of new analgesics or preparations into routine clinical practice.

Abstract
BACKGROUND The addition of clonidine to peripheral nerve blocks is controversial in children. OBJECTIVE The aim of our study was to evaluate the effect of clonidine added to ropivacaine in pediatric axillary brachial plexus block (ABPB). METHODS Children aged 1-6 years, scheduled to undergo forearm or hand surgery, were recruited into this prospective, double-blind controlled trial. Patients were randomly allocated to receive an ABPB either with ropivacaine 0.2% 0.4 ml · kg(-1) plus saline in 1 ml (RS) or ropivacaine 0.2% 0.4 ml · kg(-1) plus clonidine 1 μg · kg(-1) in 1 ml (RC). Primary endpoints were quality of postoperative analgesia as assessed by pain scores and total 24-h postoperative analgesia requirements. Secondary outcomes were time to first analgesia request and duration of motor blockade. RESULTS Sixty patients were recruited (n = 30 per group) into the study. Pain scores were comparable throughout the first 24 h between the two groups. Ten children in the (RS) and six in (RC) groups required supplementary analgesia during the first 24 h (P = 0.24). Children who required further analgesia did so after 288 ± 94 min in the (RS) and 437 ± 204 min in the (RC) group (P = 0.06). There was no difference in the duration of motor block [186 ± 71 and 154 ± 56 min, P = 0.12 for (RS) and (RC), respectively]. CONCLUSION Ropivacaine (0.2% 0.4 ml · kg(-1) ) for ABPB provides sufficient postoperative analgesia in children scheduled for forearm or hand surgery. The addition of clonidine to ABPB does not improve overall postoperative analgesia but may increase the time to first analgesia request.
