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
STUDY OBJECTIVE Caudal block helps relieve pain after sub-umbilical surgery in pediatric patients; however, the duration for which it exerts its analgesic effect is limited. The addition of certain adjuvant agents to local anesthetics (LAs) that are used to administer caudal block can prolong postoperative analgesia. Therefore, we aimed to compare the efficiencies and side effects of caudal adjuvants in the settings of pediatric lower abdominal and urological surgeries. DESIGN A network meta-analysis (NMA). PATIENTS One hundred and twelve randomized controlled trials (RCTs) involving 6800 pediatric patients were included in the final analysis. INTERVENTIONS Different adjuvant agents, namely clonidine, dexamethasone, dexmedetomidine, fentanyl, ketamine, magnesium, midazolam, morphine, neostigmine, and tramadol. MEASUREMENTS The primary outcome was the duration of analgesia. The secondary outcomes included the requirement for additional analgesia, analgesic consumption, and postoperative complications. The effects and rankings were evaluated using NMA and the surface under the cumulative ranking curve scores, respectively. RESULTS Neostigmine, dexmedetomidine, and dexamethasone were found to be the three most effective adjuvants that prolong the duration of analgesia for caudal block, and these adjuvants extended this duration by 8.9 h (95% confidence interval [CI], 7.1-10.7), 7.3 h (95% CI, 6.0-8.6), and 5.9 h (95% CI, 4.0-7.7), respectively. Caudal neostigmine was associated with an increase in the incidence of postoperative nausea and vomiting, whereas dexmedetomidine and dexamethasone showed no postoperative complications. CONCLUSIONS This NMA provided evidence and suggested that dexmedetomidine and dexamethasone may be the most beneficial adjuvant pharmaceutics adding to LAs for caudal block in children. However, given the off-label status of caudal dexmedetomidine and dexamethasone, further high-quality RCTs are still warranted, especially to determine whether delayed neurological complications will occur.

Abstract
Introduction: Postoperative analgesia is very important parameter for overall management of pediatric patients. Aims: To compare the analgesic efficacy of caudal dexmedetomidine versus caudal tramadol with bupivacaine 0.25 % in paediatric Infra-umbilical surgeries. Objectives: To study hemodynamic changes. The duration of post-operative analgesia and to compare motor block and post-operative sedation in both groups, as well as the side effects associated with analgesia in both the groups. Methods: The study was carried out in 60 patients of either sex belonging to ASA Grade-I/II between age group of 1 to 8 years undergoing infra umbilical surgeries. After taking written informed consent from all the patient's care taker, pre-anaesthetic evaluation was carried out and procedure was explained to patient's care taker. Patients were randomly devided into 2 groups. Group BT: Patient received 1 ml/kg 0.25% bupivacaine with tram-adol 1 mg/kg. Group BD: Patient received 1 ml/kg 0.25% bupivacaine with dexmedetomidine 1 µg/kg. Our method of anaesthesia was G. A. with caudal block. Postoperative analgesia was assessed by FLACC score for 24 hours and If FLACC ≥ 4, Paracetamol suppository (15 mg/kg) was given as rescue analgesia. Post-operative sedation was assessed by Ramsay sedation score up to 6 hr postoperatively. Postoperatively, all the patients were monitored for any complications like Nausea, Vomiting, Shivering, Bradaycardia, Hy-potension and Respiratory depression. Results: Patients were comparable in both the groups regarding age, weight, sex distribution (P > 0.05). Mean duration of surgery in group BT was 55.3 ± 9.6 mins, in group BD was 56.7 ±12.8 mins. There was no statistically significant difference in the duration of surgery between the two groups on intergroup comparison (p > 0.05). There was no statistically significant difference in mean heart rate, mean arterial pressure and mean oxygen saturation between the groups on intergroup comparison intraoperatively and postoperatively (p > 0.05). Ramsay Sedation score was 2.0 ± 0.4 at 1 hr posto-operatively in Group BT patients. So, after 1 hr of surgery, patients of BT group remained anxious, restless and agitated. While in group BD, Sedation score was 2.0 ± 0.3 at 6 hr postoperatively. Thus all patients remained cooperative , oriented and tranquil up to 6 hr post-operatively. Group BD had significant sedation compared to Group BT for 6 hrs postoperatively (p < 0.05). We observed significant difference between the groups in terms of FLACC score. Group BT patients achieved statistically significantly higher FLACC score compared with Group BD.(P < 0.05). The mean duration of analgesia was 6.9 ± 1.2 hr in Group BT, 13.2 ± 2.8 hr in Group RD (p < 0.05). There was a statistically significant prolongation in the duration of analgesia in Group BD (p < 0.05). In present study, incidence of nausea and vomiting occurred in 5 (16.7%) of patients in Group BT and 3 (6.7%) in Group BD. None of the patients had Shivering, Brady-cardia, Hypotension, Respiratory depression, Neurological sequale in both the groups.

Abstract
Introduction Caudal epidural block is a reliable technique in paediatric patients but associated with various complications especially with higher concentration of drugs. We proposed a comparative study between levobupivacaine and ropivacaine at low concentration (0.125%) with clonidine at low dose (1 mcg/kg) taken as adjuvant. We aimed to see duration of post-operative analgesia, degree of motor blockade and other associated complications. Materials and Methods Eighty paediatric patients (1-6 years), American society of anaesthesiologists grade I and II, undergoing infra-umbilical surgery under general anaesthesia were randomly allocated into two groups of 40 each. Group A patients were given caudal levobupivacaine (0.125%) and Group B patients were given caudal ropivacaine (0.125%). Clonidine (1 mcg/kg) was taken as adjuvant in both the groups. Post-operative pain, sedation and motor blockade were assessed at 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 18 hours and 24 hours using Observational Pain Scale, modified Bromage Scale and four-point sedation score, respectively. Any other complications were also noted. Results Motor blockade was not associated with any of the patients. Duration of post-operative sedation was similar in both the groups. Duration of post-operative analgesia was significantly higher in Group A (p < 0.0001). Adverse effects and complications were negligible in both the groups. Conclusion Both levobupivacaine and ropivacaine can be used safely at low concentration (0.125%) taking clonidine at low dose (1 mcg/kg) as adjuvant in paediatric caudal epidural block without significant motor blockade and other complications, duration of post-operative analgesia being significantly higher in the levobupivacaine group.

Abstract
The combination of morphine and ketamine is considered safe and efficacious in many patients. However, a considerable number of immunomodulatory effects have been reported to be produced by both morphine and ketamine. The aim of the present study was to assess the direct effect of morphine and a low dose of ketamine on the T cells of patients with refractory cancer pain in vitro. Venous blood was obtained from patients with refractory cancer pain and peripheral blood mononuclear cells were isolated using the Ficoll-Hypaque density gradient method. Anti-CD3 beads were used to isolate T cells by positive selection. Subsequently, the T cells were treated with vehicle, 200 ng/ml of morphine or 200 ng/ml of morphine + 100 ng/ml ketamine for 24 h, following which the cells were stimulated with anti-CD3 and anti-CD28. Flow cytometric analysis of CD3+ T cells, and interleukin (IL)-2 and interferon (IFN)-γ in the supernatant, reverse transcription-quantitative PCR analysis for the detection of IL-2 and IFN-γ and western blotting for the detection of p65 nuclear factor (NF)-κB were performed. In vitro, the CD4+ and CD8+ T cell counts, CD4+/CD8+ ratio, secretion of IL-2 and IFN-γ in the supernatant, mRNA expression levels of IL-2 and IFN-γ and expression of p65 NF-κB were significantly decreased following treatment with morphine and morphine + ketamine, compared with results in the control group (all P<0.05). However, there was no significant difference between treatment with morphine and that with morphine + ketamine. Treatment with morphine + ketamine in vitro decreased the immune functions of patients with refractory cancer pain, although the effect of treatment with morphine and a low dose of ketamine did not differ significantly from that with morphine treatment alone.

Abstract
Context Adjuvants to bupivacaine for single shot caudal block in children. Aims This study entitled was conducted to compare the effects of addition of tramadol to bupivacaine over addition of clonidine to bupivacaine as a single shot caudal block in children. Settings and Design Sixty children of ASA grade I and II in the age group of 2-12 years coming for various infra-umbilical surgeries were included. Materials and Methods They were divided into two groups of 30 each. Group BC received caudal bupivacaine 0.25% 0.5ml/kg with clonidine 2 mcg/kg Group BT received caudal bupivacaine 0.25% 0.5 ml/kg with tramadol 2 mg/kg. The main parameters studied were hemodynamic changes, duration of post-operative analgesia and incidence of adverse effects. Statistical Analysis Used The results of continuous variables are given as mean ± SD and proportion as percentage. The difference between the two groups was assessed by student's - t test and chi-square test. Results The mean duration of post-operative analgesia in group BT was statistically significant (P <0.001), reducing the requirement of analgesics in group BT. There was no difference in sedation score, nausea, vomiting, urinary retention. Conclusions The present study demonstrated that caudal administration of bupivacaine 0.25% 0.5 ml/kg with tramadol 2 mg/kg resulted in superior analgesia with longer duration of action and reduced requirement of analgesics in first 24 hours postoperatively when compared with 0.25% bupivacaine 0.5 ml/kg with clonidine 2 mcg/kg.

Abstract
PURPOSE To investigate postoperative pain control and analgesic use after heart surgery. METHODS 20 patients undergone heart surgery, randomly entered the study. Each patient was asked to score his pain intensity on visual analog scale (VAS) at four different occasions. RESULTS 120 patients aged 59 year-old; including 81 male were enrolled in the study. 69.2% had coronary artery disease and 16.7% had heart-valve problem. Main types of surgeries were coronary artery bypass surgery (70.5%) and valve repairement (23%). Duration of ICU stay was 4.78±2.7 days and duration of intubations was 17.38 ± 36.46 hours. Pre-surgery pain relief was administrated to 42% of the subjects and morphine and promethazine was the main pre-surgery analgesia medication. Post surgery analgesic included morphine (injection), petidine (injection) and NSAIDS (oral or rectal). According to VAS, mean pain level, 1 and 4 hours after extubation, and before and one hour after transferring to wards was 5.05±2.5, 4.09±2.0, 3.52±1.8, 2.36±1.89, respectively. Although the level of pain reported was mostly moderate, 80% were reported satisfaction with their post-surgery pain management. CONCLUSION A closer pain management control is needed for patients after heart surgery. Introduction of newer pain management techniques, medications and dosages could reduce the pain and suffering.

Abstract
BACKGROUND The authors calculated the effect size for post-operative analgesia of three additives, clonidine, neostigmine, and tramadol to bupivacaine, ropivacaine, or levobupivacaine used for single-dose caudal extradural blockade in children. METHODS A meta-analysis was performed for three end points of efficacy: the increase of time until administration of analgesic drugs, the proportion of patients requiring analgesic drugs during the initial 24 post-operative hours, and the amounts of post-operative analgesic drugs. A Bayesian inference supporting direct statements about the probability of the magnitude of an effect was used to compare the effects size. RESULTS Neostigmine increased the duration of analgesia by 9.96 h (95% confidence interval: 7.75 to 12.16), as compared with 3.68 h (2.65 to 4.7) with clonidine and 4.45 (2.84 to 6.07) with tramadol. There is a 95% probability that neostigmine increases the duration of post-operative analgesia by more than 8 h, clonidine by more than 2.8 h, and tramadol by more than 3.25 h, as compared with local anesthetics alone. The odds ratios for the proportion of patients requiring analgesic drugs were 0.22 [0.13 to 0.37] for clonidine and 0.28 [0.10 to 0.75] for neostigmine. With tramadol, there was no statistically significant difference. All three additives reduced the amounts of post-operative analgesic drugs. Neostigmine and tramadol increase the probability for post-operative nausea or vomiting (PONV). CONCLUSIONS Neostigmine provides the longest post-operative analgesia. With clonidine, the duration of analgesia is shorter and sedation is increased, but the probability for PONV could be decreased.

Abstract
BACKGROUND The aim of this quantitative systematic review was to assess the efficacy and adverse effects of ketamine added to caudal local anaesthetics in comparison with local anaesthetics alone in children undergoing urological, lower abdominal, or lower limb surgery. METHODS The systematic search, data extraction, critical appraisal, and pooled data analysis were performed according to the PRISMA statement. All randomized controlled trials (RCTs) were included in this meta-analysis and relative risk (RR), mean difference (MD), and the corresponding 95% confidence intervals (CIs) were calculated using the Revman(®) statistical software for dichotomous and continuous outcomes. RESULTS Thirteen RCTs (published between 1991 and 2008) including 584 patients met the inclusion criteria. There was a significant longer time to first analgesic requirements in patients receiving ketamine in addition to a local anaesthetic compared with a local anaesthetic alone (MD: 5.60 h; 95% CI: 5.45-5.76; P<0.00001). There was a lower RR for the need of rescue analgesia in children receiving a caudal regional anaesthesia with ketamine in addition to local anaesthetics (RR: 0.71; 95% CI: 0.44-1.15; P=0.16). CONCLUSIONS Caudally administered ketamine, in addition to a local anaesthetic, provides prolonged postoperative analgesia with few adverse effects compared with local anaesthetics alone. There is a clear benefit of caudal ketamine, but the uncertainties about neurotoxicity relating to the dose of ketamine, single vs repeated doses and the child's age, still need to be clarified for use in clinical practice.

Abstract
INTRODUCTION Balanced analgesia, using both opioid and nonopioids agents, has become the standard care for postoperative pain management. Ketamine, a compound with analgesic and antihyperalgesic properties, has been shown to decrease postoperative pain and opioid requirements in adults. The goal of the present meta-analysis was to investigate postoperative analgesic properties of ketamine in pediatric patients. MATERIAL AND METHODS A comprehensive literature search was conducted to identify clinical trials that used ketamine as a perioperative analgesic compound in children and infants. Outcomes measured were postoperative analgesic consumption, pain intensity and duration of sensory block (when ketamine was used by caudal route) during the postoperative care unit (PACU) stay and the early postoperative period (6-24 h after leaving the operative room). The data from each trial were combined to calculate the pooled odds ratios or standard mean differences and their 95% confidence intervals. RESULTS Thirty-five randomized, blinded controlled studies were retrieved from the literature. Systemic ketamine was effective in decreasing PACU pain intensity and analgesic requirement but failed to influence early (6-24 h) pain intensity and analgesic requirement. Ketamine administered locally during tonsillectomy, decreased PACU and early (6-24 h) pain intensity and PACU analgesic requirements. Used as an adjuvant for caudal analgesia, ketamine increased the duration of sensory block and PACU analgesic requirement without impacting PACU pain intensity. Ketamine failed to exhibit a postoperative opioid-sparing effect. CONCLUSIONS This meta-analysis found that administration of ketamine was associated with decreased PACU postoperative pain intensity and nonopioid analgesic requirement. However, ketamine failed to exhibit a postoperative opioid-sparing effect.

Abstract
INTRODUCTION Acute pain in children may be undertreated. Improved understanding of developmental neurobiology and paediatric pharmacokinetics should facilitate better management of pharmacotherapy. The objective of this review is to discuss current paediatric practice and recent advances with these analgesic agents by using an evidence-based approach. AREAS COVERED Using PubMed an extensive literature review was conducted on the commonly used analgesic agents in children from 2000 to April 2010. EXPERT OPINION A multimodal analgesic regimen provides better pain control and functional outcome in children. The choice of pharmacological treatment is determined by the severity and type of pain. However, more research and evidence is required to determine the optimal drug combinations.

Abstract
BACKGROUND Ketamine has been shown to have neurotoxic properties, when administered neuraxially. The mechanism of this local toxicity is still unknown. Therefore, we investigated the mechanism of cytotoxicity in different human cell lines in vitro. METHODS We incubated the following cell types for 24 h with increasing concentrations of S(+)-ketamine and racemic ketamine: (i) human Jurkat T-lymphoma cells overexpressing the antiapoptotic B-cell lymphoma 2 protein, (ii) cells deficient of caspase-9, caspase-8, or Fas-associated protein with death domain and parental cells, and (iii) neuroblastoma cells (SHEP). N-Methyl-d-aspartate (NMDA) receptors and caspase-3 cleavage were identified by immunoblotting. Cell viability and apoptotic cell death were evaluated flowcytometrically by Annexin V and 7-aminoactinomycin D double staining. Mitochondrial metabolic activity and caspase-3 activation were measured. RESULTS Ketamine, in a concentration-dependent manner, induced apoptosis in lymphocytes and neuroblastoma cell lines. Cell lines with alterations of the mitochondrial pathway of apoptosis were protected against ketamine-induced apoptosis, whereas alterations of the death receptor pathway did not reduce apoptosis. S(+)-Ketamine and racemic ketamine induced the same percentage of cell death in Jurkat cells, whereas in neuroblastoma cells, S(+)-ketamine was slightly less toxic. CONCLUSIONS Ketamine at millimolar concentrations induces apoptosis via the mitochondrial pathway, independent of death receptor signalling. At higher concentrations necrosis is the predominant mechanism. Less toxicity of S(+)-ketamine was observed in neuroblastoma cells, but this difference was minor and therefore unlikely to be mediated via the NMDA receptor.

Abstract
The greatest advance in pediatric pain medicine is the recognition that untreated pain is a significant cause of morbidity and even mortality after surgical trauma. Accurate assessment of pain in different age groups and the effective treatment of postoperative pain is constantly being refined; with newer drugs being used alone or in combination with other drugs continues to be explored. Several advances in developmental neurobiology and pharmacology, knowledge of new analgesics and newer applications of old analgesics in the last two decades have helped the pediatric anesthesiologist in managing pain in children more efficiently. The latter include administering opioids via the skin and nasal mucosa and their addition into the neuraxial local anesthetics. Systemic opioids, nonsteroidal anti-inflammatory agents and regional analgesics alone or combined with additives are currently used to provide effective postoperative analgesia. These modalities are best utilized when combined as a multimodal approach to treat acute pain in the perioperative setting. The development of receptor specific drugs that can produce pain relief without the untoward side effects of respiratory depression will hasten the recovery and discharge of children after surgery. This review focuses on the overview of acute pain management in children, with an emphasis on pharmacological and regional anesthesia in achieving this goal.
