Abstract
OBJECTIVE Adenoid or adenotonsillar hypertrophy (AATH) causes upper airway obstruction, leading to cardiovascular complications. This meta-analysis was conducted to evaluate the efficacy of adenoidectomy or adenotonsillectomy (AATE) on the cardiovascular system. METHODS Using the Cochrane Central Register of Controlled Trials, PubMed, and EMBASE databases, we identified studies involving a comparison of preoperative and postoperative cardiovascular function in children with AATH. The Cochrane Collaboration's Review Manager 5.3 software was used for meta-analysis. RESULTS A total of 13 studies with 706 participants were included. The meta-analysis demonstrated a significant reduction in mean pulmonary artery pressure (mPAP) of patients after AATE compared with preoperative values. The left ventricular myocardial function index (LVMPI) and the right ventricular myocardial function index (RVMPI) showed a significant decrease after the operation. Moreover, AATE prominently increased left ventricular ejection time (LVET) and right ventricular ejection time (RVET) and reduced the left ventricular interventricular septum diameter (LVIVSD) and the right ventricular end-diastolic diameter (RVedD). There was no significant difference in mPAP, LVMPI, RVMPI, LVET, RVET, LVIVSD, and RVedD between postoperative patients and healthy children (P > 0.05). CONCLUSION AATE can improve cardiovascular function in pediatric patients with AATH. Specifically, it reduces mPAP and LVMPI/RVMPI in pediatric patients. Furthermore, AATE increases LVET and RVET and reduces LVIVSD and RVedD.

Abstract
Obstructive sleep apnea (OSA) is defined by intermittent and recurrent episodes of partial or complete obstruction of the upper airway during sleep. Intermittent and recurrent hypoxia/reoxygenation is the main pathophysiological mechanism of OSA. Its consequences include systemic inflammation, activation of the sympathetic nervous system, and release of oxygen free radicals. Infusion of intravenous (IV) lidocaine has anti-inflammatory, antihyperalgesic, and analgesic properties, supporting its use as an anesthetic adjuvant. Lidocaine can reduce nociception and/or cardiovascular responses to surgical stress, as well as postoperative pain and/or analgesic requirements. Because of the high prevalence of OSA in obese patients, the use of opioids to manage postoperative pain in that population is often accompanied by the development of adverse respiratory events, such as hypoventilation and hypoxemia. IV infusion of lidocaine has been shown to enhance the quality of early recovery after laparoscopic bariatric and upper airway surgery. However, limited evidence exists regarding its use in patients undergoing surgery for OSA. In addition, whether IV infusion of lidocaine can improve postoperative early recovery in patients undergoing surgery for OSA remains unknown. Therefore, we hypothesized that IV infusion of lidocaine can improve postoperative early recovery in patients undergoing surgery for OSA. Perioperative infusion also may be a promising analgesic adjunct to enhanced recovery after surgery (ERAS) protocols.

Abstract
There have been significant advancements in the safe delivery of anesthesia as well as improvements in surgical technique; however, the perioperative period can still be high risk for the pediatric patient. Perioperative respiratory complications (PRCs) are some of the most common critical events that can occur in pediatric surgical patients and they can lead to increased length of hospitalization, worsened patient outcomes, and higher hospital and postoperative costs. It is important to determine the various factors that put pediatric patients at increased risk of PRCs. This will allow for more detailed and accurate informed consent, optimized perioperative management strategy, improved allocation of clinical resources, and, hopefully, better patient experience. There are only a few risk prediction models/scoring tools developed for and validated in the pediatric patient population, but they have been useful in helping identify the key factors associated with a high likelihood of developing PRCs. Some of these factors are patient factors, while others are procedure-related factors. Some of these factors may be modified such that the patient’s clinical status is optimized preoperatively to decrease the risk of PRCs occurring perioperatively. Fore knowledge of the factors that are not able to be modified can help guide allocation of perioperative clinical resources such that the negative impact of these non-modifiable factors is buffered. Additional training in pediatric anesthesia or focused expertise in pediatric airway management, vascular access and management of massive hemorrhage should be considered for the perioperative management of the less than 3 age group. Intraoperative ventilation strategy plays a key role in determining respiratory outcomes for both adult and pediatric surgical patients. Key components of lung protective mechanical ventilation strategy such as low tidal volume and moderate PEEP used in the management of acute respiratory distress syndrome (ARDS) in pediatric intensive care units have been adopted in pediatric operating rooms. Adequate post-operative analgesia that balances pain control with appropriate mental status and respiratory drive is important in reducing PRCs.

Raghavan K, Moo DXY, Tan Z. Severe obesity in children as an independent risk factor for perioperative respiratory adverse events during anaesthesia for minor non-airway surgery, a retrospective observational study. PROCEEDINGS OF SINGAPORE HEALTHCARE 2019.

Abstract
Purpose: The purpose of this article is to quantify grades of obesity and their independent effects on perioperative adverse events in children having ambulatory minor non-airway surgery. Methods: After obtaining ethics committee approval, we selected every tenth child aged 2 to 16 years who was identified as having been a day case between January 2012 and December 2014. Weight groups were defined based on age- and gender-specific body mass index (BMI) cutoff points. A sample size of 1102 was calculated to demonstrate a three-fold increase in the primary outcome measure, perioperative respiratory-airway adverse events, among obese children, with a power of 80% and an alpha error of 5%. Chi-squared and Fisher exact tests were used to compare proportions, and independent sample t tests were used to compare means. Results: Severely obese children had a significantly higher incidence of perioperative respiratory-airway adverse events when compared to normal-weight children despite no difference in respiratory and other comorbidity. Obese children had higher prevalence of overall medical comorbidities and obstructive sleep apnoea when compared to normal-weight children and there was no significant difference in the incidence of perioperative respiratory-airway adverse events and other outcome measures between obese and normal-weight children. Conclusions and recommendations: Severely obese children have a higher risk of perioperative respiratory-airway adverse events even during minor non-airway surgery despite absence of medical comorbidities. We recommend the use of age- and sex- specific BMI cutoffs or BMI percentile charts to identify children who are severely obese to anticipate and prevent major respiratory adverse events.

Abstract
STUDY OBJECTIVES There are few studies measuring postoperative respiratory complications in obese children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy (AT). These complications are further compounded by perioperative medications. Our objective was to study obese children with OSA for their respiratory characteristics and sleep architecture on the night of AT. METHODS This was a prospective study at a tertiary pediatric hospital between January 2009-February 2012. Twenty obese children between 8-17 years of age with OSA and adenotonsillar hypertrophy were recruited. Patients underwent baseline polysomnography (PSG) and AT with or without additional debulking procedures, followed by a second PSG on the night of surgery. Demographic and clinical variables, surgical details, perioperative anesthetics and analgesics, and PSG respiratory and sleep architecture parameters were recorded. Statistical tests included Pearson correlation coefficient for correlation between continuous variables and chi-square and Wilcoxon rank-sum tests for differences between groups. RESULTS Baseline PSG showed OSA with mean obstructive apnea-hypopnea index (oAHI) 27.1 ± 22.9, SpO2 nadir 80.1 ± 7.9%, and sleep fragmentation-arousal index 25.5 ± 22.0. Postoperatively, 85% of patients had abnormal sleep studies similar to baseline, with postoperative oAHI 27.0 ± 34.3 (P = .204), SpO2 nadir, 82.0 ± 8.7% (P = .462), and arousal index, 24.3 ± 24.0 (P = .295). Sleep architecture was abnormal after surgery, showing a significant decrease in REM sleep (P = .003), and a corresponding increase in N2 (P = .017). CONCLUSIONS Obese children undergoing AT for OSA are at increased risk for residual OSA on the night of surgery. Special considerations should be taken for postoperative monitoring and treatment of these children. COMMENTARY A commentary on this article appears in this issue on page 775.

Abstract
PURPOSE OF REVIEW Clinical studies and new guidelines are frequently being published in the area of preoperative fasting. A growing population of patients with obstructive sleep apnea is being referred for outpatient procedures including adenotonsillectomy. RECENT FINDINGS Recently published preoperative fasting guidelines for pediatric patients are covered along with studies comparing gastric volume following different fasting intervals. Pediatric obstructive sleep apnea is discussed. Clinical presentation, severity, perioperative risks, and controversies as whether outpatient procedures are suitable for these patients are presented. New data covering different perioperative aspects are presented. SUMMARY A more liberal preoperative intake is encouraged with fasting for 2 h for clear liquids, 4 h for breast milk, 6 h for formula and light meals, and 8 h for heavy meals is widely accepted. Interpersonal variation in residual gastric volume exists. Children with obstructive sleep apnea under 3 years of age and those with severe obstructive sleep apnea and comorbidities are not candidates for ambulatory surgery. Polysomnography has specific preoperative indications. Dexmedetomidine can decrease emergence agitation and has an opioid-sparing effect. Intravenous acetaminophen is presented as an opioid-sparing analgesic. Dexamethasone is effective in preventing postoperative nausea without increased risk of bleeding. Surgical techniques may affect postoperative pain.

Abstract
PURPOSE To discuss developments in paediatric anaesthesia and explore the factors which have contributed to improved anaesthetic-related patient outcomes. METHODS Narrative review of findings in the literature retrieved from MEDLINE/Pubmed and manual search. RESULTS Adverse perioperative outcomes related to anaesthesia have been extensively debated over the past few decades, with studies implicating factors such as major human error and equipment failure. Case series and event registries have enlightened physicians on sources of error and patient risk factors such as extremes of age, comorbidity and emergent circumstances. Anaesthetic-related deaths in children fell from 6.4 per 10,000 anaesthetics in the early 1950s to as low as 0.1 per 10,000 anaesthetics by the end of the century. Advances in anaesthetic agents, techniques, monitoring technologies and training programmes in paediatric anaesthesia play a vital role in driving this downward trend. CONCLUSION Despite substantial progress, there is still much room for improvement in areas such as adverse-event reporting, anaesthetic-related risk and late neurocognitive outcomes. Systematic reviews comparing paediatric patient outcomes after neuroaxial block versus general anaesthesia are currently unavailable. The future of paediatric anaesthesia will most likely be influenced by much-needed large prospective studies, which can provide further insight into patient safety and service delivery.

Abstract
Adenoid hypertrophy is the most common cause of pediatric upper airway obstruction, and it can lead to cardiopulmonary complications such as pulmonary hypertension, cor pulmonale, and even heart failure. The aim of this study was to detect the asymptomatic cardiopulmonary changes that could happen in children with adenoid hypertrophy.Eighty children with adenoid hypertrophy were included in this study. Chest x-ray was used to assess the cardiothoracic ratio, whereas echocardiography was used for measuring the pulmonary arterial pressures, right ventricular diastolic filling parameters, and right ventricular end-diastolic diameters. All patients underwent adenoidectomy with or without tonsillectomy, and they were subjected again to echocardiographic assessment 6 months after the operation. No patient showed an increase in the cardiothoracic ratio on x-ray. Preoperative echocardiography showed an increase in pulmonary artery pressure (22.7 [SD, 3.8] mm Hg), a decrease in right ventricular diastolic filling parameters (E/A = 1.03 [SD, 0.17]), and an increase in right ventricular end-diastolic diameters (1.89 [SD, 0.19] cm). Postoperatively, pulmonary artery pressure decreased to 17.2 [SD, 2.1] mm Hg, right ventricular diastolic filling (E/A) increased to 1.25 [SD, 0.11], and right ventricular end-diastolic diameters decreased to 1.68 [SD, 0.12] cm. The comparison between preoperative and postoperative results for each individual parameter was statistically significant. Clinically asymptomatic cardiopulmonary changes due to adenoid hypertrophy are not rare. Early diagnosis and treatment of upper airway obstruction can prevent these serious complications. Echocardiographic examination should be recommended for these patients as a part of preoperative preparation to avoid anesthetic complications.

Abstract
The care of the child having ambulatory surgery presents a specific set of challenges to the anesthesia provider. This review focuses on areas of clinical distinction that support the additional attention children often require, and on clinical controversies that require providers to have up-to-date information to guide practice and address parental concerns. These include perioperative risk; obstructive sleep apnea; obesity; postoperative nausea and vomiting; neurocognitive outcomes; and specific concerns regarding common ear, nose, and throat procedures.

Abstract
Obstructive sleep apnoea (OSA) correlates positively with obesity and age, both of which are becoming increasingly prevalent. Obstructive sleep apnoea occurs much more frequently in clinical practice than formerly diagnosed, and that this condition represents complex challenges for difficulty in mask ventilation, laryngoscopic intubation, accelerated arterial desaturation, postoperative monitoring and discharge status. In this review article pathophysiology, diagnosis, and perioperative management of this group of patients have been discussed in detail.

Abstract
Obstructive sleep apnoea syndrome (OSAS) is a common medical disorder among adults, which is increasingly being recognized in children too. It is a breathing disorder characterized by upper airway obstruction with or without intermittent complete obstruction that disrupts normal breathing during sleep. Anatomical and neuromuscular disorders are mainly responsible for this disorder. This disorder leads to a state of chronic hypoxemia, which has significant cardiac, pulmonary and central nervous system implications. Diagnosis of OSAS is based on thorough history and clinical examination along with appropriate sleep studies including polysomnography. The mainstay of treatment of paediatric OSAS is adenotonsillectomy. Good anaesthetic practice in Paediatric patients with OSAS revolves around good and ideal airway management. Early detection of airway obstruction, intense monitoring to warn of impending airway problems and appropriate and early intervention of airway compromise are good anaesthetic practices. Coexisting medical problems should be adequately addressed and safe analgesic techniques in the perioperative period go towards improving outcomes in patients with paediatric OSAS.

Abstract
The prevalence of childhood obesity has more than tripled over the past five decades. Obesity results in low lung volumes, likely through increased loading of the chest wall and abdomen. The prevalence of asthma in children has paralleled the rise in obesity; obesity may increase the severity of asthma, but a direct link has been difficult to establish. Obesity is a risk factor for obstructive sleep apnea (OSA) in children as well as adults. Obese children may be at increased risk for persistent OSA following adenotonsillectomy treatment for OSA. Severe obesity and OSA may lead to the obesity-hypoventilation syndrome, with hypoxia, hypercapnia, and reduced ventilatory drive. Obesity can increase a child's risk for complications of anesthesia and recovery from surgery.

Abstract
Obstructive sleep apnea syndrome (OSA) affects 1%-3% of children. Children with OSA can present for all types of surgical and diagnostic procedures requiring anesthesia, with adenotonsillectomy being the most common surgical treatment for OSA in the pediatric age group. Thus, it is imperative that the anesthesiologist be familiar with the potential anesthetic complications and immediate postoperative problems associated with OSA. The significant implications that the presence of OSA imposes on perioperative care have been recognized by national medical professional societies. The American Academy of Pediatrics published a clinical practice guideline for pediatric OSA in 2002, and cited an increased risk of anesthetic complications, though specific anesthetic issues were not addressed. In 2006, the American Society of Anesthesiologists published a practice guideline for perioperative management of patients with OSA that noted the pediatric-related risk factor of obesity, and the increased perioperative risk associated with adenotonsillectomy in children younger than 3 yr. However, management of OSA in children younger than 1 yr-of-age was excluded from the guideline, as were other issues related specifically to the pediatric patient. Hence, many questions remain regarding the perioperative care of the child with OSA. In this review, we examine the literature on pediatric OSA, discuss its pathophysiology, current treatment options, and recognized approaches to perioperative management of these young and potentially high-risk patients.

Abstract
STUDY OBJECTIVES Polysomnographic respiratory events in children should be scored using pediatric respiratory rules. However, due to a lack of data on adolescents, recently revised rules allow children aged 13-18 years to be scored by adult or pediatric criteria. To clarify which criteria to use, we describe the evolution of respiratory events with Tanner stage, and we compare events in children aged 13-18 years with the new American Academy of Sleep Medicine adult and pediatric respiratory rules. DESIGN Cross-sectional SETTING Academic hospital PARTICIPANTS Healthy subjects aged 8-18 years recruited for research purposes. INTERVENTIONS Physical examination to determine Tanner stage, overnight polysomnogram, and determination of sex hormones. RESULTS Sixty-eight subjects (Tanner 1-5) were studied, mean age [SD] = 13 +/- 3 years, median apnea hypopnea index (AHI)= 0.1 (range: 0-1.2)/h. The median percentages of total sleep time (TST) with SpO2 < 92% were 0.1 (0-4.2)%, and with end-tidal CO2 > 50 torr was 0.1 (0-88.6)%. Thirty-two subjects were aged 13-18 years, (Tanner 3-5). The difference between AHI scored by pediatric (median = 0 [0-0.9]/h) and adult (median = 0 [0 - 0.5]/h) criteria was statistically significant (P = 0.043), but not clinically relevant. CONCLUSIONS Respiratory events in normal children aged 8-18 years are rare and unrelated to Tanner stage. Adult or pediatric respiratory rules can be used for scoring polysomnograms in asymptomatic subjects approaching adulthood. Further studies are needed in symptomatic children within this age group.
