World J Otorhinolaryngol Head Neck Surg 2023; 9:9-26. [PMID: 37006744 PMCID: PMC10050970 DOI: 10.1002/wjo2.54] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 12/23/2021] [Indexed: 12/15/2022] Open
Abstract
Objectives To examine the volume, topics, and reporting trends in the published literature of randomized clinical trials for pharmacologic pain management of pediatric tonsillectomy and adenotonsillectomy and to identify areas requiring further research. Data Sources PubMed (National Library of Medicine and National Institutes of Health), Scopus (Elsevier), CINAHL (EBSCO), and Cochrane Library (Wiley). Methods A systematic search of four databases was conducted. Only randomized controlled or comparison trials examining pain improvement with a pharmacologic intervention in pediatric tonsillectomy or adenotonsillectomy were included. Data collected included demographics, pain-related outcomes, sedation scores, nausea/vomiting, postoperative bleeding, types of drug comparisons, modes of administration, timing of administration, and identities of the investigated drugs. Results One hundred and eighty-nine studies were included for analysis. Most studies included validated pain scales, with the majority using visual-assisted scales (49.21%). Fewer studies examined pain beyond 24 h postoperation (24.87%), and few studies included a validated sedation scale (12.17%). Studies have compared several different dimensions of pharmacologic treatment, including different drugs, timing of administration, modes of administration, and dosages. Only 23 (12.17%) studies examined medications administered postoperatively, and only 29 (15.34%) studies examined oral medications. Acetaminophen only had four self-comparisons. Conclusion Our work provides the first scoping review of pain and pediatric tonsillectomy. With drug safety profiles considered, the literature does not have enough data to determine which treatment regimen provides superior pain control in pediatric tonsillectomy. Even common drugs like acetaminophen and ibuprofen require further research for optimizing the treatment of posttonsillectomy pain. The heterogeneity in study design and comparisons weakens the conclusions of potential systematic reviews and meta-analyses. Future directions include more noninferiority studies of unique comparisons and more studies examining oral medications given postoperatively.

Abstract
Although ketamine is primarily used for induction and maintenance of general anesthesia, it also presents sedative, amnestic, anesthetics, analgesic, antihyperalgesia, neuroprotective, anti-inflammatory, immunomodulant, and antidepressant effects. Its unique pharmacodynamics and pharmacokinetic properties allow the use of ketamine in various clinical settings including sedation, ambulatory anesthesia, and intensive care practices. It has also adopted to manage acute and chronic pain management. Clinically, ketamine produces dissociative sedation, analgesia, and amnesia while maintaining laryngeal reflexes, with respiratory and cardiovascular stability. Notably, it does not cause respiratory depression, maintaining both the hypercapnic reflex and the residual functional capacity with a moderate bronchodilation effect. In the pediatric population, ketamine can be administered through practically all routes, making it an advantageous drug for the sedation required setting such as placement of difficult vascular access and in uncooperative and oppositional children. Consequently, ketamine is indicated in prehospital induction of anesthesia, induction of anesthesia in potentially hemodynamic unstable patients, and in patients at risk of bronchospasm. Even more, ketamine does not increase intracranial pressure, and it can be safely used also in patients with traumatic brain injuries. This article is aimed to provide a brief and practical summary of the role of ketamine in the pediatric field.

Abstract
Adequate pain management is important for successful postoperative recovery after any surgical procedure. Unfortunately, the USA and many other parts of the world are in the midst of an opioid epidemic, and healthcare providers are thus tasked with balancing the comfort and recovery of their patients after an operation against the individual and societal harms of the over-prescription of opioids. The goal of this article is to discuss the range of opioid formulations currently in use, examine why this may be problematic, and explore alternatives that provide similar efficacy and may improve overall safety in the pediatric population after urologic surgery. Improving the way opioids are prescribed through clinical practice guidelines as well as considering alternatives to opioids can ensure patients have access to safer and more effective pain treatments and potentially reduce opioid misuse.

Abstract
INTRODUCTION The comparison of ketamine with tramadol for pain control remains controversial in pediatric adenotonsillectomy or tonsillectomy. We conduct a systematic review and meta-analysis to explore the efficacy of ketamine vs tramadol for pain relief in children following adenotonsillectomy or tonsillectomy. METHODS We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through October 2019 for randomized controlled trials (RCTs) assessing the effect of ketamine vs tramadol for pediatric adenotonsillectomy or tonsillectomy. This meta-analysis is performed using the random-effects model. RESULTS Six RCTs are included in the meta-analysis. Overall, compared to ketamine group for pediatric adenotonsillectomy or tonsillectomy, tramadol is associated with substantially lower CHEOPS at 1 h (SMD = 1.56; 95% CI = 0.20-2.92; P = .02; low quality) and longer first time of additional pain medication (SMD = -0.47; 95% CI = -0.74 to -0.19; P = .0008; low quality), but demonstrates no obvious effect on CHEOPS at 6 h (SMD = 0.51; 95% CI = -1.17 to 2.19; P = .55; low quality), sedation scale at 1 h (SMD = -0.80; 95% CI = -3.07 to 1.48; P = .49; low quality) or additional pain medication (RR = 1.31; 95% CI = 0.85-2.02; P = .23; moderate quality). CONCLUSIONS Tramadol may be better to alleviate the postoperative pain after pediatric adenotonsillectomy or tonsillectomy.

Low-dose ketamine adjuvant treatment for refractory pain in children, adolescents and young adults with cancer: a pilot study. BMJ Support Palliat Care 2019; 12:e656-e663.

Abstract
OBJECTIVES Ketamine, an N-methyl-D-aspartate receptor antagonist, is effective at relieving adult cancer pain, although there have been very few reports to date regarding its use in children and in adolescents and young adults (AYA). This study assessed the efficacy, safety and opioid-sparing effects of low doses of ketamine added to opioid analgesics to alleviate persistent cancer pain. METHODS This prospective, multicentre, observational trial collected data regarding demographics, pain characteristics, pain score assessment within the first 48 hours of ketamine administration, tolerance and satisfaction from 38 patients aged 2-24 years prescribed with ketamine as an adjuvant antalgic for refractory cancer pain in 10 French paediatric oncology centres. RESULTS The mean visual analogue scale pain score decreased from 6.7 to 4.3 out of 10 (n=39, p<0.001) from day 1 to day 3 and by at least 2 points in 56% of the patients (n=22) 48 hours after initiation of ketamine. Nine patients experienced poor tolerance (≥2 side effects), all with infusion rates lower than 0.05 mg/kg/hour. None had limiting toxicities. An opioid-sparing effect was highlighted in four patients. Fifty-four per cent of the prescribers and 47% of the patients found the addition of ketamine 'very helpful'. CONCLUSIONS Low doses of ketamine as an adjuvant to opioids significantly reduced the intensity of pain in half of the study population. A tendency towards better pain control is shown, although a lack of statistical power somewhat limits our conclusions, especially in children. Nevertheless, ketamine may be a useful option for improving the treatment of refractory pain in children and AYA with cancer.

Abstract
Pain is a common and highly distressing symptom in pediatric patients with advanced malignancies. Prompt recognition, assessment, and treatment of pain are necessary, especially at the end of life. Opioid medications remain the mainstay of treatment of malignant pain in children at the end of life and the amount of opioids required for adequate pain control in patients is highly variable. Nonpharmacological approaches including behavioral and physical approaches in addition to non-opioid pain medications should be used when possible to augment pain control. Identification and treatment of any underlying pathology is important and use of adjuvant medications based on pathophysiology and source of pain should be considered. In cases where adequate pain control is not achieved through these multiple modalities, an interdisciplinary approach including potential interventional techniques and alternative treatments is required. This multimodal approach to pain management is best provided by interdisciplinary teams, as these teams can best address the complex causes of pain and associated distress that occurs in patients and within families.

Abstract
OBJECTIVES Tonsillectomy is the oldest and most frequently performed surgical procedure practiced by ear, nose, and throat physicians. In this study, our aim was to compare the analgesic effects of peritonsillar, rectal, as well as intravenous infiltration of ketamine and intravenous tramadol hydrochloride infiltration for postoperative pain relief and sedation after tonsillectomy in children. MATERIALS AND METHODS This randomized controlled study evaluated the effects of peritonsillar, intravenous, and rectal infiltration of ketamine in children undergoing adenotonsillectomy. One hundred twenty children who were categorized under American Society of Anesthesiologists classes I to II were randomized to 4 groups of 30 members each. Group 1 received intravenous (IV) ketamine (0.5 mg/kg), group 2 received rectal ketamine (0.5 mg/kg), group 3 received local peritonsillar ketamine (2 mg/kg), and the control group received IV tramadol hydrochloride infiltration (2 mg/kg). Children's Hospital of Eastern Ontario Pain Scale scores and Wilson sedation scale were recorded at minutes 1, 15, 30, 60 as well as hours 2, 12, and 24 postoperatively. The patients were interviewed on the day after the surgery to assess the postoperative pain and sedation. RESULTS All the routes of infiltration of ketamine were as effective as those of tramadol hydrochloride (P > 0.05). A statistically significant difference was observed between IV infiltrations and all groups during the assessments at hours 6 and 24. The analgesic efficacy of IV ketamine was found especially higher at hours 6 and 24 (P(6) = 0.045, P(24) = 0.011). CONCLUSIONS Perioperative, low-dose IV, rectal, or peritonsillar ketamine infiltration provides efficient pain relief without any adverse effects in children who would undergo adenotonsillectomy.

Abstract
OBJECTIVES To evaluate if the pre-emptive administration of ketamine would potentiate the effect of intravenous morphine analgesia in the management of post-thoracotomy pain. METHODS This was a unicentre, double-blind, placebo-controlled, parallel-group, prospective study. Patients were randomly assigned to receive 1 mg/kg ketamine (ketamine group) or an equivalent dose of normal saline (placebo group) before thoracotomy in 1:1 ratio. All patients received postoperatively intravenous morphine administration as additional analgesic regimen. Primary end-point was the pain relief measured with Visual Analogue Scale at rest. The secondary end-points were the reduction of inflammatory response expressed by plasma C-reactive protein levels, the morphine consumption and the rate of side effects. The measurements were carried out 6, 12, 24, 36 and 48 hours postoperatively. RESULTS A total of 75 patients were randomized of whom 38 were allocated to ketamine group and 37 to placebo group. Baseline characteristics were comparable. Ketamine compared with placebo group showed a significant reduction of pain scores (P = 0.01), C-reactive protein (P < 0.001) and morphine consumption (P < 0.001). No acute psychological side effects related to the use of ketamine were registered. CONCLUSIONS The administration of ketamine before surgery may be an effective adjunct to intravenous morphine analgesia in acute post-thoracotomy pain management. In ketamine group, satisfaction of pain relief was significantly higher with a significant reduction of inflammatory response and morphine consumption compared with placebo group. Our results, if confirmed by larger studies, may be of clinical relevance in situations where epidural analgesia or other analgesic procedures different from systemic opioid analgesia are unavailable or contraindicated.

Abstract
OBJECTIVE Tonsillectomy surgery is associated with severe postoperative pain that usually requires analgesics including opioids. Pain control is still a big problem after tonsillectomy surgery. We aimed to evaluate the efficacy of preemptive analgesia using montelukast for pediatric post-tonsillectomy pain management. This is the first-time use of montelukast in post-tonsillectomy pain. STUDY DESIGN Double-blind, controlled-randomized study. SETTINGS University teaching and research hospital. SUBJECTS AND METHODS A total of 60 children, aged 5 to 15 years, American Society of Anesthesiologist class I-II, scheduled for elective tonsillectomy were enrolled in this clinical trial study. The patients were randomized into 2 groups: the montelukast group (group M, n = 30) and control group (group C, n = 30). Group M recieved an oral montelukast tablet and group C recieved placebo at 2400pm on the morning before surgery. Post-tonsillectomy pain was evaluated with the Wong-Baker FACES Scale during the 24 hours after surgery. Patients' intraoperative hemodynamic parameters and intraoperative and postoperative complications were recorded. RESULTS There were statistically significant differences between group C and group M for Wong-Baker FACES pain rating scale scores (P < .05). In the 24 hours after surgery, the total number of patients using rescue analgesics was higher in group C than in group M, and the difference was statistically significant (P < .001). There was no significant difference in demographic parameters (P > .05). There were no significant differences in postoperative nausea and vomiting, otalgia, trismus, fever, or halitosis between the groups (P > .05). CONCLUSION Preemptive montelukast can be used safely to reduce the serious pain caused by tonsillectomy in children.

Efficacy of ketamine in improving pain after tonsillectomy in children: meta-analysis. PLoS One 2014; 9:e101259.

Abstract
BACKGROUND AND OBJECTIVES The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. SUBJECTS AND METHODS Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or opioid administration (opioid group) where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination) 0-24 hours after leaving the operation room were included in the analysis. RESULTS The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration) regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. CONCLUSION Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

Abstract
Primary cleft palate repair may result in significant pain in the immediate postoperative period, which can lead to vigorous crying resulting in wound dehiscence and pulmonary complications. Effective pain control with opioids is the mainstay but administration on the floor has to be countered with the complications associated with their use, chiefly respiratory depression and sedation. We retrospectively examined the efficacies of intraoperative administration of intravenous (IV) dexmedetomidine (DEX) and ketamine (KET) to prevent early postoperative pain in children undergoing primary cleft palate repair and compared the results against relevant literature. The Texas Children's Hospital anesthesia database was queried to identify children undergoing a palatal surgery from December 2011 to December 2012. Inclusion criteria permitted completed primary palatal surgery without major complications and intraoperative administration of DEX or KET. The control group (CTRL) received no additional drug. A comprehensive literature review was performed. A total of 71 pediatric patients underwent palatal surgery during the study period with 46 patients qualifying for analysis. Although results were not significant, consistent trends were observed with regards to lower opioid requirements during the first 24 hours for both medications compared with the CTRL. KET also had shorter time to discharge. The literature review resulted in several studies supporting decreased postoperative pain end points for both DEX and KET. In our sample, DEX and KET reduced postoperative opioid requirements. KET seems to have the added benefit of a shorter hospital stay. These finding are supported in the literature. With further investigation, the addition of these drugs may serve to provide improved pain relief without over sedation in patients undergoing cleft palate repair.

Abstract
Obstructive sleep apnea (OSA) is more common in surgical candidates than in the general population and may increase susceptibility to perioperative complications that range from transient desaturation to catastrophic injuries. Understanding the potential impact of OSA on patients' surgical risk profile is of particular interest to otolaryngologists, who routinely perform airway procedures-including surgical procedures for treatment of OSA. Whereas the effects of OSA on long-term health outcomes are well documented, the relationship between OSA and surgical risk is not collinear, and clear consensus on the nature of the association is lacking. Better guidelines for optimization of pain control, perioperative monitoring, and surgical decision making are potential areas for quality improvement efforts. Many interventions have been suggested to mitigate the risk of adverse events in surgical patients with OSA, but wide variations in clinical practice remain. We review the current literature, emphasizing recent progress in understanding the complex pathophysiologic interactions noted in OSA patients undergoing surgery and outlining potential strategies to decrease perioperative risks.

Adenotonsillectomy has a high incidence of postoperative pain. Therefore, the purpose of this study was to evaluate the effectiveness and safety of either ketamine or fentanyl for postoperative pain relief in children following adenotonsillectomy. Sixty children aged 3-12 years, scheduled for adenotonsillectomy, were enrolled in this randomized, double-blind study. Patients were divided into two groups of 30 cases and received intravenous ketamine (0.5 mg kg(-1)) or fentanyl (1 microg kg(-1)). Modified Hannallah pain scale or Observational Pain Scores (OPS), nausea, vomiting, bleeding, rescue analgesia, sedation and post-anesthesia recovery scores were recorded both at first and 15th minute postoperatively. Moreover, patients receiving ketamine (group 1) or fentanyl (group 2) had comparable OPS and sedation score both on arrival and at 15th minute in the recovery room (p > 0.05). Although rescue analgesics were similarly required in both groups (p > 0.05), the time to reach rescue analgesia was shorter in group 1 (p = 0.001). Only one patient in fentanyl group had nausea and vomiting in the first 15 min that needed antiemetic in the recovery room. In conclusion, intravenous fentanyl (1 microg kg(-1)) compared with intravenous ketamine (0.5 mg kg(-1)) might provide extended time to first analgesic in children undergoing adenotonsillectomy. Interestingly, fentanyl and ketamine did not differ in post-operative vomiting.

Abstract
STUDY OBJECTIVE To evaluate the efficacy and the quality of recovery with intravenous (IV) paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children. DESIGN Prospective, randomized, double-blinded clinical trial. SETTING Operating room and Postanesthesia Care Unit (PACU) of a university-affiliated hospital. PATIENTS 64 ASA physical status I and II children, aged 6 to 16 years, scheduled for adenotonsillectomy. INTERVENTIONS All patients were premedicated with oral midazolam 0.5 mg/kg 30 minutes before surgery. Patients were randomized to two groups following induction of general anesthesia. The paracetamol group (n = 32) received 15 mg/kg of IV paracetamol and the tramadol group (n = 32) received 1.0 mg/kg of IV tramadol. MEASUREMENTS Modified Hannallah pain scores, emergence agitation, Aldrete scores, sedation scores, time to first administration of analgesic, heart rate, and mean arterial blood pressure were recorded for each patient. Data were recorded every 5 minutes for the first 30 minutes and every 10 minutes for the remaining 30 minutes in the PACU, then at 2, 3, 4, 5, 6, 8, 12, and 24 hours in the ward. The frequency of postoperative nausea and vomiting also was noted. Satisfaction of parents and nurses was determined on a 4-point scale at the end of the study. MAIN RESULTS No significant demographic differences between groups were noted. No statistically significant difference was found in postoperative pain scores in either group. Agitation scores, Aldrete scores, sedation scores, and number of patients who received rescue analgesia and time to administration of rescue analgesia were similar in both groups. CONCLUSIONS The IV formulation of paracetamol was associated with similar analgesic properties and early recovery to that of IV tramadol after adenotonsillectomy in children.

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
OBJECTIVE To evaluate the efficacy of preoperative intravenous or peritonsillar infiltration of ketamine for postoperative pain control in children following adenotonsillectomy. PATIENTS AND METHODS 78 children between 5 and 18 years of age who were scheduled for elective adenotonsillectomy were randomly assigned to four groups: group 1 (n = 19) received intravenous ketamine (0.5 mg/kg), group 2 (n = 21) intravenous normal saline, group 3 (n = 19) ketamine (0.5 mg/kg) injected through the tonsillar capsule, and group 4 (n = 19) normal saline injected in the same location. The incidence of postoperative pain and vomiting as well as the severity of postoperative pain were compared between study groups during the 6-hour postoperative period using a visual analog scale (VAS) at rest, upon swallowing saliva, drinking liquids and eating ice cream. RESULTS There were no demographic differences between the four groups. The incidence of postoperative pain was significantly lower in groups 1 [7 (36.8%) vs. 10 (47.6%); p = 0.032] and 3 [5 (31.5%) vs. 12 (63.2%); p = 0.001] compared with their controls. The amount (in milligrams) of pethidine and metoclopramide used for pain and nausea control was significantly lower in groups 1 (12.5 ± 5.3 vs. 19.6 ± 9.6 mg, p = 0.038, and 2.9 ± 1.1 vs. 4.6 ± 2.6 mg, p = 0.042, respectively) and 3 (8.6 ± 3.1 vs. 21.6 ± 8.4 mg, p < 0.001, and 1.6 ± 0.9 vs. 5.3 ± 3.2 mg, p = 0.002, respectively) compared with their controls. These values were also higher in group 1 compared with group 3. The VAS scores on swallowing saliva (3.9 ± 2.7 vs. 2.7 ± 1.2; p = 0.018), on drinking liquids (3.7 ± 2.6 vs. 2.8 ± 1.6; p = 0.013) and on eating ice-cream (4.3 ± 2.4 vs. 2.8 ± 1.5; p = 0.001) were also significantly higher in group 1 compared with group 3. CONCLUSIONS Our results show that peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity, need for analgesics and need for antiemetics. Thus, peritonsillar infiltration of ketamine is suggested for postoperative pain control in those undergoing adenotonsillectomy.

Abstract
Ketamine has found many applications in pediatric anesthetic practice. Insights into the mechanism of action and the pharmacokinetics and pharmacodynamics of its isomers have led to a re-evaluation of this drug, expanding the range of applications in children. Ketamine is a remarkably versatile drug that can be administered through almost any route. It can also be used for different purposes. The aim of this review is to look at the possible applications of this drug in children.

The effect of preoperative fasting on postoperative pain, nausea and vomiting in pediatric ambulatory tonsillectomy. Int J Pediatr Otorhinolaryngol 2009; 73:263-73.

Abstract
OBJECTIVE The aim of this prospective randomized study was to examine whether active counseling and more liberal oral fluid intake decrease postoperative pain, nausea and vomiting in pediatric ambulatory tonsillectomy. METHODS Families, whose child was admitted for ambulatory tonsillectomy or adenotonsillectomy, were randomly assigned to the study groups (n=116; 58 families in each group). The intervention group received the fasting instructions with face-to-face counseling for the child's active preoperative nutrition, and the control group the fasting instructions according to the hospital's standard procedure. The level of postoperative pain and nausea was scored in the postanesthesia care unit (PACU) during the first postoperative hour, as well as at 2, 4, 8 and 24h postoperatively. The first scoring in PACU was performed by the attending nurse with a 0-10 scale. The rest of the estimations were made independently and simultaneously by the children using a VAS scale, and by the parents using a 0-10 scale. RESULTS The children in the control group were in more pain in the PACU than the children in the intervention group, and the difference between the groups was statistically significant (p=0.0002). All pain scores, according to the children and the parents, increased after the surgery. In both groups the highest score values were found at home 8h after surgery, and no significant difference was found between the study groups. On the first postoperative morning, the children in the control group were in pain (p=0.047). The children did not have significant nausea in the PACU, but the nausea increased postoperatively. Four hours after surgery the children were most nauseous according to all estimations (60%, n=116). More than half of the children vomited and most vomited clotted blood. Nausea and vomiting decreased during the evening of the surgery, but six children vomited the next morning, four of them vomited blood. The incidence and intensity of postoperative nausea and vomiting between the intervention and control groups were not statistically significant. However, preoperative nutritional counseling and more liberal per oral fluid intake appeared to have a positive effect on the children's well-being and helped them to better tolerate postoperative nausea and vomiting. CONCLUSIONS The preoperative counseling about active preoperative nutrition significantly reduces the child's pain during the first posttonsillectomy hours and might prepare the child to better tolerate the stress of potential postoperative nausea and vomiting.

Abstract
BACKGROUND Tonsillectomy is one of the most frequently performed operations in children and frequently associated with moderate-to-severe pain. OBJECTIVES The aim of the present study was to assess the effect of a subhypnotic dose of ketamine on postoperative pain and morphine consumption after tonsillectomy in children. METHODS This randomized double-blind study involved 84 children, 2 to 12-year-olds, undergoing elective outpatient tonsillectomy. Children were assigned to 2 groups. Group K received morphine and ketamine, 0.25 mg/kg, at induction and Group M received morphine. Modified Children's Hospital of Eastern Ontario (mCHEOP) scale was used to evaluate postoperative pain. Pain, morphine consumption, and unwanted side effects were recorded for a 24-hour period. One-way analysis of variance and chi2 tests were used for statistical analysis. RESULTS Pain scores and adverse events were similar between the 2 groups. Although morphine consumption was less in the ketamine group during the immediate postoperative period, total morphine consumption over the course of the study was not significantly different between the 2 groups. Fewer patients in the ketamine group required supplementary oral analgesia in the postoperative surgical unit. CONCLUSIONS The addition of ketamine 0.25 mg/kg at induction of anesthesia did not decrease postoperative morphine consumption in children undergoing tonsillectomy.

Abstract
The management of pain in children with life-limiting illnesses is complex and unfortunately not often done effectively. Pain is a multidimensional symptom that can overshadow all other experiences of both the child and family. This article focuses on topics common to practitioners caring for children with lifelimiting illnesses, including a review of myths and obstacles to achieving adequate pain control, a review of the pathophysiology of pain, an overview of the use of opioids in children, an approach to the management of neuropathic pain, and a brief discussion of nonpharmacologic pain management strategies.

Abstract
STUDY OBJECTIVES To evaluate the effectiveness of ketamine in the prevention of postoperative pain after tonsillectomy. DESIGN Randomized, prospective, double-blind study. SETTING University hospital. PATIENTS 90 ASA physical status I and II patients, aged 5 to 15 years, scheduled for tonsillectomy or adenotonsillectomy. INTERVENTIONS Patients were divided into three groups. The pain preventive group received intravenous (IV) ketamine 0.5 mg/kg in 2 mL saline before the tonsils were surgically removed, followed by a continuous IV infusion of ketamine at 6 micro/(kg/min). In the ketamine group, 2 mL saline was given before the tonsils were surgically removed; saline infusion (10 mL/h) was continued until bleeding control, and 0.8 mg/kg ketamine was given during bleeding control in 2 mL saline. In the control group, only saline was given. MEASUREMENTS AND MAIN RESULTS Cardiorespiratory system data, recovery from anesthesia and discharge parameters, tramadol requirement, and complications were recorded. Recovery from anesthesia and discharge parameters were similar among the groups. Total dose of tramadol was lower in the pain preventive group than in the other groups. In the pain preventive group, verbal pain scale scores were lower in the early postoperative period in the fourth and sixth hours (P < 0.05). CONCLUSIONS Ketamine decreases postoperative analgesic requirements and has analgesic effects when used before surgery in tonsillectomy/adenotonsillectomy.

Abstract
BACKGROUND A few previous studies have suggested the efficacy of i.v. ketamine for postoperative pain relief in children after adenotonsillectomy, but none has investigated the efficacy of peritonsillar infiltration of ketamine in these children. METHODS This randomized, placebo-controlled study evaluated the effects of peritonsillar infiltration of ketamine in children undergoing adenotonsillectomy. Ninety ASA I-II children were randomized three groups of 30 each. Group I received: 2 ml i.v. saline, group II received i.v. ketamine (0.5 mgxkg(-1)) and group III received a local peritonsillar infiltration of ketamine (0.5 mgxkg(-1)). All medications were 2 ml in volume which was applied 1 ml per tonsil 3 min prior to tonsillectomy. Modified Hannallah pain scale [observational pain scores (OPS)], nausea, vomiting, bleeding, rescue analgesia, sedation and Aldrete scores were recorded at first, 15th, 30th and 60th min postoperatively. Patients were interviewed on the day after surgery to assess the postoperative pain, nightmares, hallucinations, vomiting and bleeding. RESULTS Group I had higher OPS scores than group II and group III. Group II and group III had comparable scores, which were not statistically significant (P > 0.05). Group II had higher sedation score at 15th min (P = 0.015). Thirty-two children, 19 of whom were in group I had rescue analgesia in postanesthesia care unit (P < 0.05) and the time to first analgesic requirement was significantly shorter in group I than the other groups (P = 0.006). Group II and group III also had less pain than group I at home (P = 0.023). CONCLUSIONS Low dose ketamine given i.v. or by peritonsillar infiltration perioperatively provides efficient pain relief without side-effects in children undergoing adenotonsillectomy.

Abstract
In this systematic review effectiveness of analgesics for pain after tonsillectomy in children was evaluated and trial methodology of the included studies explored. Databases were searched for randomised, controlled studies on systemic paracetamol, NSAIDs and opioids. Eighty-four studies were evaluated for inclusion. Thirty-six studies were included and 48 excluded. Only in two studies investigated analgesics were given postoperatively for pain. All other studies investigated prophylactic administration of analgesics. Only five studies were truly placebo controlled. Trial methodology of the included studies varied greatly in respect to analgesics and doses used, duration of follow-up periods, methods of pain measurement, rescue analgesics and criteria for administrating rescue analgesia used. Sensitivity of studies was often unclear. Only 16 out of 36 studies were considered to be sensitive. Because of highly variable methodology and lack of sensitivity only limited conclusions on clinical efficacy of analgesics investigated can be drawn. No analgesic in single prophylactic dose provided analgesia for day of operation. Further studies are needed to find the optimal analgesic(s) for pain after tonsillectomy in children.

Abstract
BACKGROUND Obstructive sleep apnoea/hypopnoea syndrome(OSAHS) is the periodic reduction or cessation of airflow during sleep. The syndrome is associated with loud snoring, disrupted sleep and observed apnoeas. Surgery for obstructive sleep apnoea/hypopnoea syndrome aims to alleviate symptoms of daytime sleepiness, improve quality of life, and reduce the signs of sleep apnoea recorded by polysomnography. OBJECTIVES The objective of this review was to assess the effects of any type of surgery for the treatment of the symptoms of obstructive sleep apnoea/hypopnoea syndrome in adults. SEARCH STRATEGY We searched the Cochrane Airways Group Specialised Register and reference lists of articles. We contacted experts in the field, research dissemination bodies and other Cochrane Review Groups. Searches were current as of July 2005. SELECTION CRITERIA Randomised trials comparing any surgical intervention for obstructive sleep apnoea/hypopnoea syndrome with other surgical or non-surgical interventions or no intervention. DATA COLLECTION AND ANALYSIS Two reviewers assessed electronic literature search results for possibly relevant studies. Characteristics and data from studies meeting the inclusion criteria were extracted and entered into RevMan 4.2. MAIN RESULTS In the 2005 update for this review eight studies (412 participants) of mixed quality met the inclusion criteria. Data from seven studies were eligible for assessment in the review. No data could be pooled. Uvulopalatopharyngoplasty (UPPP) versus conservative management (one trial): An un validated symptom score showed intermittent significant differences over a 12-month follow-up period. No differences in Polysomnography (PSG) outcomes were reported. Laser-assisted uvulopalatoplasty (LAUP) versus conservative management/placebo (two trials): One study recruited mixed a population, and separate data could not be obtained for this trial. In the other study no significant differences in Epworth scores or quality of life reported. A significant difference in favour of LAUP was reported in terms of apnoea hypopnoea index (AHI) and frequency and intensity of snoring. UPPP versus oral appliance (OA) (one trial): AHI was significantly lower with OA therapy than with UPPP. No significant differences were observed in quality of life. UPPP versus lateral pharyngoplasty (lateral PP) (one trial): No significant difference in Epworth scores, but a greater reduction in AHI with lateral PP was reported. Tongue advancement (mandibular osteotomy) + PPP versus tongue suspension + PPP (one trial): There was a significant reduction in symptoms in both groups, but no significant difference between the two surgery types. Complications reported with all surgical techniques included nasal regurgitation, pain and bleeding. These did not persist in the long term. An additional study assessed the effects of four different techniques. No data were available on between group comparisons. Multilevel temperature-controlled radiofrequency tissue ablation (TCRFTA) versus sham placebo and CPAP (one trial): There was an improvement in primary and secondary outcomes of TCRFTA over sham placebo and but no difference in symptomatic improvement when compared with CPAP. AUTHORS' CONCLUSIONS There are now a small number of trials assessing different surgical techniques with inactive and active control treatments. The studies assembled in the review do not provide evidence to support the use of surgery in sleep apnoea/hypopnoea syndrome, as overall significant benefit has not been demonstrated. The participants recruited to the studies had mixed levels of AHI, but tended to suffer from moderate daytime sleepiness where this was measured. Short-term outcomes are unlikely to consistently identify suitable candidates for surgery. Long-term follow-up of patients who undergo surgical correction of upper airway obstruction is required. This would help to determine whether surgery is a curative intervention, or whether there is a tendency for the signs and symptoms of sleep apnoea to re-assert themselves, prompting patients to seek further treatment for sleep apnoea.

BMC Anesthesiol 2005; 5:2.

Abstract
BACKGROUND: Despite preclinical evidence suggesting a synergistic interaction between ketamine and opioids promoting analgesia, several clinical trials have not identified dosing regimens capable of eliciting a benefit in the co-administration of ketamine with opioids. METHODS: Ten healthy volunteers participated in a double blinded, randomised, placebo controlled, crossover laboratory study in order to determine whether a low dose of ketamine potentiated the antinociceptive effect of fentanyl without causing an increase in sedative effects. A battery of tests was used to assess both nociception and sedation including electrical current, pressure, thermal stimuli, psychometric tests, and both subjective and objective scores of sedation. Target controlled infusions of the study drugs were used. Ketamine and fentanyl were administered alone and in combination in a double-blinded randomised crossover design. Saline was used as the control, and propofol was used to validate the tests of sedation. Cardiovascular and respiratory parameters were also assessed. RESULTS: The electrical current pain threshold dose response curve of fentanyl combined with ketamine was markedly steeper than the dose response curve of fentanyl alone. While a ketamine serum concentration of 30 ng/ml did not result in a change in electrical pain threshold when administered alone, when it was added to fentanyl, the combination resulted in greater increase in pain threshold than that of fentanyl administered alone. When nociception was assessed using heat and pressure stimuli, ketamine did not potentiate the anti-nociceptive effect of fentanyl. There was no difference between the sedative effect of fentanyl and fentanyl in combination with ketamine as assessed by both subjective and objective measures of sedation. Cardiovascular and respiratory parameters were unaffected by the study drugs at the doses given. CONCLUSION: A serum concentration of ketamine that did not alter indices of sedation potentiated the antinociceptive effect of fentanyl. This potentiation of antinociception occurred without an increase in sedation suggesting that low steady doses of ketamine (30-120 ng/ml) might be combined with mu opioid agonists to improve their analgesic effect in a clinical setting.

Abstract
OBJECTIVES To further evaluate the safety profile and efficacy of intramuscular ketamine for procedural sedation during paediatric minor procedures in the emergency department and to ascertain parental satisfaction with the treatment of their children. METHODS A prospective audit of ketamine use in a UK district general hospital involving 89 children requiring minor procedures. Children received topical anaesthesia followed by an intramuscular injection of ketamine 4 mg/kg and intramuscular atropine 0.02 mg/kg. The procedure was assessed by way of a physician completed form and by evaluation of questionnaires given to parents to gauge levels of satisfaction. RESULTS No child required admission to hospital and there were no serious complications. A high level of satisfaction was expressed by all the parents/guardians of the children treated. CONCLUSIONS High levels of satisfaction among parents and staff together with the avoidance of hospital admission and improved resource management should be a sufficient incentive for hospital trusts to consider the establishment of this type of service.

Abstract
At least 60% of all pediatric surgical procedures are performed as outpatients. Successful outpatient practice requires that both the patients and the procedures are appropriate for outpatient management. Appropriate scheduling ensures that the overall function of the outpatient unit is not compromised. While not all scheduled patients need be perfectly healthy, care must be taken to provide adequate resources to those patients who are not, without diverting resources away from other patients. Anesthesia must be managed with attention to the unique physiologic and psychological challenges of children. Anesthetic management of postoperative nausea and vomiting and provision of adequate postoperative analgesia, including regional techniques, are important elements of the care plan.

Abstract
BACKGROUND Establishment of good analgesia is of major concern in the postoperative period following adenotonsillectomy. The aim of this study was to compare the effects of ketamine, morphine and tramadol on postoperative pain after adenotonsillectomy in children. METHODS Sixty children (age 5-12 years) scheduled for adenotonsillectomy were randomized into four groups to receive intravenously (i.v.) either 0.5 mg.kg(-1) ketamine hydrochloride (K), 0.1 mg x kg(-1) morphine hydrochloride (M), 1.5 mg x kg(-1) tramadol hydrochloride (T) or normal saline (S) in a volume of 4 ml during induction. After tracheal intubation 10 microg x kg(-1).min(-1) ketamine hydrochloride in group K and 0.6 ml x kg(-1) x h(-1) saline i.v. in groups M, K and S were infused peroperatively. Postoperative analgesic requirements and side-effects were recorded. Pain was assessed by the Numeric Rating Scale (NRS) and the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) scores. RESULTS Heart rate increased significantly peroperatively only in group K. NRS at first and fifth minute in group M and at first minute in group T and K and CHEOPS score at first, fifth, 15th and 60th min in group M were found to be significantly lower than in the control group. The time to first analgesic requirement was significantly longer in group M compared with ketamine and the control group. Six children in group M, nine in group T, 11 in group K and 15 in group S needed additional analgesics. CONCLUSIONS Morphine hydrochloride 0.1 mg x kg(-1) i.v. administered during induction of anaesthesia provides efficient pain relief in children undergoing adenotonsillectomy.

Abstract
UNLABELLED We evaluated in a qualitative systematic review the effect of N-methyl-D-aspartate (NMDA) receptor antagonists on reducing postoperative pain and analgesic consumption beyond the clinical duration of action of the target drug (preventive analgesia). Randomized trials examining the use of an NMDA antagonist in the perioperative period were sought by using a MEDLINE (1966-2003) and EMBASE (1985-2003) search. Reference sections of relevant articles were reviewed, and additional articles were obtained if they evaluated postoperative analgesia after the administration of NMDA antagonists. The primary outcome was a reduction in pain, analgesic consumption, or both in a time period beyond five half-lives of the drug under examination. Secondary outcomes included time to first analgesic request and adverse effects. Forty articles met the inclusion criteria (24 ketamine, 12 dextromethorphan, and 4 magnesium). The evidence in favor of preventive analgesia was strongest in the case of dextromethorphan and ketamine, with 67% and 58%, respectively, of studies demonstrating a reduction in pain, analgesic consumption, or both beyond the clinical duration of action of the drug concerned. None of the four studies examining magnesium demonstrated preventive analgesia. IMPLICATIONS We evaluated, in a qualitative systematic review, the effect of N-methyl D-aspartate antagonists on reducing postoperative pain and analgesic consumption beyond the clinical duration of action of the target drug (preventive analgesia). Dextromethorphan and ketamine were found to have significant immediate and preventive analgesic benefit in 67% and 58% of studies, respectively.

Abstract
PURPOSE OF REVIEW The controversy over preemptive analgesia continues unabated, with studies both supporting and refuting its efficacy. The timing of an analgesic intervention and presence of a placebo control may have significant impact on the interpretation of results and may have led to the premature conclusion that preemptive analgesia is of limited clinical utility. A review of the recent literature using strict definitions of preemptive and preventive analgesia is required in order to clarify the broader issue of the benefits of perioperative analgesia. RECENT FINDINGS A total of 27 studies, published from April 2001 to April 2002, were found to evaluate preemptive (n = 12) or preventive analgesia (n = 15). Evidence for a benefit of preventive analgesia was strong, with 60% of studies finding reduced pain or analgesic consumption beyond the clinical duration of action of the analgesic intervention. Evidence for a benefit of preemptive analgesia was equivocal, with 41.7% of studies demonstrating that preincisional treatment reduces pain or analgesic consumption to a greater extent than does postincisional treatment. SUMMARY Studies that used a preventive design had a greater likelihood of finding a beneficial effect. The application of preventive perioperative analgesia (not necessarily preincisional) is associated with a significant reduction in pain beyond the clinical duration of action of the analgesic agent, in particular for the N-methyl-D-aspartate antagonists. The classical definition of preemptive analgesia should be abandoned in favor of preventive analgesia. This will broaden the scope of inquiry from a narrow focus on preincisional versus postincisional interventions to one that aims to minimize postoperative pain and analgesic requirements by reducing peripheral and central sensitization arising from noxious preoperative, intraoperative and postoperative inputs.
