Cerium oxide nanoparticles (nanoceria) pretreatment attenuates cell death in the hippocampus and cognitive dysfunction due to repeated isoflurane anesthesia in newborn rats

General anesthetics exposure, particularly prolonged or repeated exposure, is a crucial cause of neurological injuries. Notably, isoflurane (ISO), used in pediatric anesthesia practice, is toxic to the developing brain. The relatively weak antioxidant system at early ages needs antioxidant support to protect the brain against anesthesia. Cerium oxide nanoparticles (CeO2-NPs, nanoceria) are nano-antioxidants and stand out due to their unique surface chemistry, high stability, and biocompatibility. Although CeO2-NPs have been shown to exhibit neuroprotective and cognitive function-facilitating effects, there are no reports on their protective effects against anesthesia-induced neurotoxicity and cognitive impairments. Herein, Wistar albino rat pups were exposed to ISO (1.5 %, 3-h) at postnatal day (P)7+P9+P11, and the protective properties of CeO2-NP pretreatment (0.5 mg/kg, intraperitoneal route) were investigated for the first time. The control group at P7+9+11 received 50 % O2 (3-h) instead of ISO. Exposure to nanoceria one-hour before ISO protected hippocampal neurons of the developing rat brain against apoptosis [determined by hematoxylin-eosin (HE) staining, immunohistochemistry (IHC) analysis with caspase-3, and immunoblotting with Bax/Bcl2, cleaved caspase-3 and PARP1] oxidative stress, and inflammation [determined by immunoblotting with 4-hydroxynonenal (4HNE), nuclear factor kappa-B (NF-κB), and tumor necrosis factor-alpha (TNF-α)]. CeO2-NP pretreatment also reduced ISO-induced learning (at P28–32) and memory (at P33) deficits evaluated by Morris Water Maze. However, memory deficits and thigmotactic behaviors were detected in the agent-control group; elimination of these harmful effects will be possible with dose studies, thus providing evidence supporting safer use. Overall, our findings support pretreatment with nanoceria application as a simple strategy that might be used for pediatric anesthesia practice to protect infants and children from ISO-induced cell death and learning and memory deficits.

Anesthesia for an infant with congenital mediastinal mass: a case report

BackgroundGiant anterior mediastinal masses in infants are one of the most challenging cases faced in pediatric anesthesia practice. They can pose unique challenges for resection such as cardiovascular collapse on induction of anesthesia and injury to surrounding structures that maybe compressed or displaced. Principles that must be followed and kept in mind during removal of giant mediastinal mass include appropriate diagnostic imaging to define mass extent, airway control during induction, a multidisciplinary team approach including cardiothoracic for sternotomy, cannulation to institute cardiopulmonary bypass, otolaryngology for rigid bronchoscopy, preservation of neurovascular structure, and complete resection whenever possible. Our patient had a mass that weighed twice his whole body weight.Case presentationHere we present a 3-month-old Middle Eastern infant weighing 3.2 kg with a large congenital teratoma who presented to the emergency room with cyanosis and respiratory distress. During his hospital course, he underwent three procedures, two of them under light-to-moderate sedation: a diagnostic computer tomography scan followed by mass content drainage by interventional radiology (Figs. 1, 2). On the third day, he had a thoracotomy with complete tumor resection under general anesthesia with the help of an epidural for pain control (Fig. 3). The resected tumor weighed 2.5 kg, which was equal to twice the patient’s total body weight (Fig. 4). After the surgery, he was extubated in the operating room and discharged home 3 days later.Fig. 1Anterior–posterior chest x-ray showing the anterior mediastinal mass (AMM)Fig. 2Cross-section computed tomography (CT) showing large anterior mediastinal mass (AMM)Fig. 3Gross anatomy of the tumor before resectionFig. 4Gross anatomy of the removed tumorConclusionAnterior mediastinal mass patients can be challenging for the anesthesiologist. They need meticulous thorough perioperative assessment to determine the extent of compression on major intramediastinal structures and to predict the complications. Planning by multidisciplinary team and discussion with the family is important. These types of cases should be preferably operated on by an experienced team in a well-equipped operation room in tertiary care institutes.

Extubation and removal of supraglottic airway devices in pediatric anesthesia.

In pediatric anesthesia, respiratory adverse events often occur during emergence from anesthesia and at the time of endotracheal tube or supraglottic device removal. The removal of airway devices and extubation are conducted either while patients are deeply anesthetized or when patients awaken from anesthesia and have regained consciousness. The airways of children are easily irritated by external stimuli and are structurally prone to collapse, and the timing of both methods of airway device removal is similarly associated with various airway complications, including upper airway obstruction, coughing, or serious adverse events such as laryngospasm and desaturation. In current pediatric anesthesia practice, the choice of the timing and method of extubation is made by anesthesiologists. To achieve a smooth and safe recovery from anesthesia, understanding the unique characteristics of pediatric airways and the factors likely to contribute to an increased risk of perioperative complications remains essential. These factors include patient age, comorbidities, and physical conditions. The level of anesthesia and readiness for removal of airway devices should be evaluated carefully for each patient, and quick identification of airway problems and intervention is required if patients fail to maintain the airway and sufficient ventilation after removal of airway devices.

Advances in pediatric anesthesia services over the past 10 years in French-speaking sub-Saharan Africa.

To improve and maintain quality and safety in anesthesia, standards have been proposed regarding human resources, facilities and equipment, medications and intravenous fluids, monitoring, and the conduct of anesthesia. Compliance with these standards remains a challenge in French-speaking sub-Saharan Africa (SSA) and results in high morbidity and mortality particularly in children. This aim of this study was to assess the progress made in improving the pediatric anesthesia infrastructures, human resources, education, medications, and equipment in French-speaking SSA over the past 10 years (2013-2022). This is a descriptive, multicenter, cross-sectional study with retrospective data collection, conducted from September 1 to November 5, 2023. Comparative data from 2012 to 2022 were collected through an online survey. Descriptive statistics were used to summarize data. Data were obtained from 12 countries out of 14. The number of hospitals providing pediatric surgery and anesthesia rose from 94 in 2012 to 142 in 2022 (+51%). The total number of physician anesthesiologists rose from 293 (0.1 physician anesthesiologists/100 000 inhabitants) in 2012 to 597 (0.2 physician anesthesiologists/100 000 inhabitants) in 2022 (+103.7%). Five (0.006 physician anesthesiologists/100 000 children) had completed a fellowship in pediatric anesthesia and intensive care in 2012, and 15 (0.01 physician anesthesiologists/100 000 children) in 2022 (+200%). Five physician anesthesiologists had an exclusive pediatric anesthesia practice in 2012, whereas they were 32 in 2022 (+540%). There is no specialized training in pediatric anesthesia and intensive care in any of these countries. Halothane was always available in 81.5% of the hospitals in 2012, and in 50.4% of the hospitals in 2022. Sevoflurane was always available in 5% of the hospitals in 2012, and in 36.2% in 2022. Morphine was always available in 32.2% in 2012, whereas it was available in 52.9% of them in 2022. Pediatric pulse oximeter sensors were available in 36% of the hospitals in 2012, and in 63.4% in 2022. Capnography was available in 5.3% of the hospitals in 2012, and in 48% in 2022. Progress have been made over the last 10 years in French-speaking SSA to improve infrastructures, human resources, education, medications, and equipment for pediatric anesthesia in French-speaking SSA. However, major efforts must be continued. Standards adapted to the local context should be formulated.

The Prevalence of Difficult Airway and Associated Risk Factors in Pediatric Patients: A Cross-sessional Observational Study.

Difficult airway remains a great challenge in pediatric anesthesia practice. Previously published data show the prevalence of difficult airways in pediatric population varies in a wide range. However, there is a lack of studies in the Asian region. This cross-sectional single-center study was conducted in a tertiary pediatric hospital in China from October 2022 to October 2023. The patients who underwent elective surgery under general anesthesia with tracheal intubation were recruited consecutively. Data on patient characteristics, airway assessment, and airway management information were collected. Multivariable logistic regression analysis was performed to detect the independent variables of difficult airway in pediatric patients. A total of 18,491 pediatric patients were included in this study. The overall incidence of difficult airways was 0.22%, 39% of whom were unanticipated. Very few previous airway management information was available in the patients presented with a known difficult airway. Patients with younger age, higher American Society of Anesthesiologists (ASA) physical status classification grade, and presented for craniofacial and thoracic surgery were associated with higher incidence of difficult airway. Further multivariable logistic regression analysis revealed that age ≤28 days (OR=50.48), age between 28days and 1 year (OR=6.053), craniofacial surgery (OR=1.81), and thoracic surgery (OR=0.2465) were independent risk factors of increased incidence of difficult airway. Our study showed the prevalence of difficult airways in pediatric surgical patients. Patient characteristics, age, and type of surgery were identified as the independent factors associated with increased occurrence of difficult airways. Unanticipated difficult airway was not unusual in our study population, even for the patients with previous surgical history.

Pediatric anesthesia in Europe: Variations within uniformity.

Organization of healthcare strongly differs between European countries and results in country-specific requirements in postgraduate medical training. Within the European Union (EU), the European Board of Anaesthesiology has set recommendations of training for the Specialty of Anaesthesiology including standards for Postgraduate Medical Specialist training including a description for providing service in pediatric anesthesia. However, these standards are advisory and not mandatory. Here we aimed to review the current state and associated challenges of pediatric anesthesia training in Europe. We report an important country-specific variability both in training and regulations of practice of pediatric anesthesia in the EU and in the United Kingdom. The requirements for training in pediatric anesthesia varies between nothing specified (Belgium) or providing anesthesia with direct supervision to a minimum of 50 cases below 5 years of age (Germany) to 3-6 month clinical practice in a specialized pediatric hospital (France). Likewise, the regulations for providing anesthesia to children varies from no regulations at all (Belgium) to age specific requirements and centralization of all children below 4 years of age to specified centers (United Kingdom). Officially recognized pediatric anesthesia fellowship programs are not available in most countries of Europe. It remains unclear if and how country-specific differences in pediatric anesthesia training are associated with clinical outcomes in pediatric perioperative care. There is converging interest and support for the establishment of a European pediatric anesthesia curriculum.

Peri-operative cardiac arrest in children as reported to the 7th National Audit Project of the Royal College of Anaesthetists.

The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest. An activity survey estimated UK paediatric anaesthesia annual caseload as 390,000 cases, 14% of the UK total. Paediatric peri-operative cardiac arrests accounted for 104 (12%) reports giving an incidence of 3 in 10,000 anaesthetics (95%CI 2.2-3.3 per 10,000). The incidence of peri-operative cardiac arrest was highest in neonates (27, 26%), infants (36, 35%) and children with congenital heart disease (44, 42%) and most reports were from tertiary centres (88, 85%). Frequent precipitants of cardiac arrest in non-cardiac surgery included: severe hypoxaemia (20, 22%); bradycardia (10, 11%); and major haemorrhage (9, 8%). Cardiac tamponade and isolated severe hypotension featured prominently as causes of cardiac arrest in children undergoing cardiac surgery or cardiological procedures. Themes identified at review included: inappropriate choices and doses of anaesthetic drugs for intravenous induction; bradycardias associated with high concentrations of volatile anaesthetic agent or airway manipulation; use of atropine in the place of adrenaline; and inadequate monitoring. Overall quality of care was judged by the panel to be good in 64 (62%) cases, which compares favourably with adults (371, 52%). The study provides insight into paediatric anaesthetic practice, complications and peri-operative cardiac arrest.

Factors Associated With Decision to Use and Dosing of Sugammadex in Children: A Retrospective Cross-Sectional Observational Study.

Sugammadex was initially approved for reversal of neuromuscular blockade in adults in the United States in 2015. Limited data suggest sugammadex is widely used in pediatric anesthesia practice however the factors influencing use are not known. We explore patient, surgical, and institutional factors associated with the decision to use sugammadex versus neostigmine or no reversal, and the decision to use 2 mg/kg vs 4 mg/kg dosing. Using data from the Multicenter Perioperative Outcomes Group (MPOG) database, an EHR-derived registry, we conducted a retrospective cross-sectional study. Eligible cases were performed between January 1, 2016 and December 31, 2020, for children 0 to 17 years at US hospitals. Cases involved general anesthesia with endotracheal intubation and administration of rocuronium or vecuronium. Using generalized linear mixed models with institution and anesthesiologist-specific random intercepts, we measured the importance of a variety of patient, clinician, institution, anesthetic, and surgical risk factors in the decision to use sugammadex versus neostigmine, and the decision to use a 2 mg/kg vs 4 mg/kg dose. We then used intraclass correlation statistics to evaluate the proportion of variance contributed by institution and anesthesiologist specifically. There were 97,654 eligible anesthetics across 30 institutions. Of these 47.1% received sugammadex, 43.1% received neostigmine, and 9.8% received no reversal agent. Variability in the choice to use sugammadex was attributable primarily to institution (40.4%) and attending anesthesiologist (27.1%). Factors associated with sugammadex use (compared to neostigmine) include time from first institutional use of sugammadex (odds ratio [OR], 1.08, 95% confidence interval [CI], 1.08-1.09, per month, P < .001), younger patient age groups (0-27 days OR, 2.59 [2.00-3.34], P < .001; 28 days-1 year OR, 2.72 [2.16-3.43], P < .001 vs 12-17 years), increased American Society of Anesthesiologists [ASA] physical status (ASA III: OR, 1.32 [1.23-1.42], P < .001 ASA IV OR, 1.71 [1.46-2.00], P < .001 vs ASA I), neuromuscular disease (OR, 1.14 (1.04-1.26], P = .006), cardiac surgery (OR, 1.76 [1.40-2.22], P < .001), dose of neuromuscular blockade within the hour before reversal (>2 ED95s/kg OR, 4.58 (4.14-5.07], P < .001 vs none), and shorter case duration (case duration <60 minutes OR, 2.06 [1.75-2.43], P < .001 vs >300 minutes). Variation in sugammadex use was primarily explained by institution and attending anesthesiologist. Patient factors associated with the decision to use sugammadex included younger age, higher doses of neuromuscular blocking agents, and increased medical complexity.

The halothane era in pediatric anesthesia: The convergence of a cardiac depressant anesthetic with the immature myocardium of infancy.

Introduced in the late 1950s, halothane became the anesthetic of choice for inhalational induction of children for over 40 years. Halothane enjoyed a generally favorable safety record during its time, but its cardiac contractility depressant effect-well tolerated by most age groups-was profoundly heightened in neonates and infants, leading to increased incidences of hypotension and cardiac arrest. The neonatal myocardium is immature and is characterized by poor ventricular compliance, poor contractility due to fewer contractile elements, immature sympathetic innervation with decreased norepinephrine stores, and immature mechanisms for storage and exchange of calcium in the sarcoplasmic reticulum. Invitro studies of myocardial contractility of mammalian fetal and adult myocardium demonstrated that the fetal heart was twice as sensitive to halothane as the adult. Clinical studies demonstrated that most neonates and infants less than 6 months of age experienced hypotension during halothane induction of anesthesia and significantly (p < .01) greater decreases in blood pressure than older children at equipotent concentrations of halothane. Intraoperative cardiac arrest during the halothane era occurred over twice as frequently in neonates aged less than 1 month than in infants aged 1-12 months and nearly 10 times more frequently than children 1-5 years of age. Halothane was associated with 66% of intraoperative drug-related cardiac arrests in children. The halothane era began to close in the late 1990s with the introduction of sevoflurane, which had a more favorable hemodynamic profile. Shortly thereafter, halothane was completely displaced from pediatric anesthesia practice in North America.

Implementation of an electroencephalogram-guided propofol anesthesia practice in a large academic pediatric hospital: Aquality improvement project.

Propofol-based total intravenous anesthesia is gaining popularity in pediatric anesthesia. Electroencephalogram can be used to guide propofol dosing to the individual patient to mitigate against overdosing and adverse events. However, electroencephalogram interpretation and propofol pharmacokinetics are not sufficiently taught in training programs to confidently deploy electroencephalogram-guided total intravenous anesthesia. We conducted a quality improvement project with the smart aim of increasing the percentage of electroencephalogram-guided total intravenous anesthesia cases in our main operating room from 0% to 80% over 18 months. Balancing measures were number of total intravenous anesthesia cases, emergence times, and perioperative emergency activations. The project key drivers were education, equipment, and electronic health record modifications. Plan-Do-Study-Act cycles included: (1) providing journal articles, didactic lectures, intraoperative training, and teaching documents; (2) scheduling electroencephalogram-guided total intravenous anesthesia teachers to train faculty, staff, and fellows for specific cases and to assess case-based knowledge; (3) adding age-based propofol dosing tables and electroencephalogram parameters to the electronic health record (EPIC co, Verona, WI); (4) procuring electroencephalogram monitors (Sedline, Masimo Inc). Electroencephalogram-guided total intravenous anesthesia cases and balancing measures were identified from the electronic health record. The smart aim was evaluated by statistical process control chart. After the four Plan-Do-Study-Act cycles, electroencephalogram-guided total intravenous anesthesia increased from 5% to 75% and was sustained at 72% 9 months after project completion. Total intravenous anesthesia cases/mo and number of perioperative emergency activations did not change significantly from start to end of the project, while emergence time for electroencephalogram-guided total intravenous anesthesia was greater statistically but not clinically (total intravenous anesthesia without electroencephalogram [16 ± 10 min], total intravenous anesthesia with electroencephalogram [18 ± 9 min], sevoflurane [17 ± 9 min] p < .001). Quality improvement methods may be deployed to adopt electroencephalogram-guided total intravenous anesthesia in a large academic pediatric anesthesia practice. Keys to success include education, in operating room case training, scheduling teachers with learners, electronic health record modifications, and electroencephalogram devices and supplies.

The accuracy of the ultrasound measured transverse cricoid diameter and the epiphyseal transverse diameter of the distal radius in predicting the pediatric endotracheal tube size.

In everyday pediatric anesthesia practice, clinicians frequently exchange an already inserted endotracheal tube because of a leak or resistance causing significant morbidity. We investigated the accuracy of two ultrasound measurements; the transverse cricoid diameter and epiphyseal diameter of the distal radius in the prediction of endotracheal tube size that best fits in children compared to age-based formulas. One hundred children (1-6 years) who underwent elective surgery with endotracheal tube whether cuffed (n = 50) or uncuffed (n = 50) were enrolled. The primary endpoint was the agreement between the reference tube size for which its outer diameter was selected based on transverse cricoid diameter and the final best-fit-ETT. The Correlation and Bland Altman agreement tests were conducted between best-fit-ETT outer diameter and ultrasound-measured outer diameter, and between best-fit-ETT inner diameter and inner diameter calculated by age-based formulas. The agreement rate between transverse cricoid diameter-based endotracheal tube size and best-fit-ETT size was 88% in cuffed group compared to 90% in uncuffed group. A significant positive correlation was reported between the outer diameter of best-fit-ETT and the outer diameter measured by the two ultrasound methods. A lower degree of positive correlation was reported between the inner diameter of best-fit-ETT, and the inner diameter calculated by age-based formulas. Bland Altman's analysis showed agreement between best-fit-ETT outer diameter and epiphyseal diameter of the distal radius in both groups and with transverse cricoid diameter in the cuffed group, with no agreement with age-based formulas in either group. Both transverse cricoid diameter and epiphyseal diameter of the distal radius are reliable predictors of the size of best-fit-ETT pediatric endotracheal tube compared to age-based formulas. To save time and effort, we recommend the US measurement of the epiphyseal diameter of distal radius in the preoperative visit and documenting the predicted tube size with the preoperative assessments.

A Comparative Study of Intramuscular Ketamine and a Combination of Intramuscular Dexmedetomidine and Ketamine as Premedication in Paediatric Anesthesia

Introduction: Preoperative anxiety is an issue of concern in paediatric anaesthesia practice. Forceful transfer of children into the operating room can cause long-term psychological trauma. This clinical study compares intramuscular ketamine and a combination of intramuscular dexmedetomidine and ketamine as anaesthetic premedicants in terms of +anxiolysis, sedation and ease of IV cannulation.&#x0D; Objectives: To compare the level of preoperative anxiety, sedation and ease of cannulation following premedication between intramuscular ketamine and a combination of intramuscular dexmedetomidine and ketamine.&#x0D; Methods: Total of 60 patients belonging to American Society of Anaesthesiologists physical status I-II, in the age group of two to ten years, scheduled for elective surgery under general anaesthesia were included in the study; Group A patients received ketamine 3mg/kg body weight while Group B patients received ketamine 2mg/kg body weight and dexmedetomidine 1mcg/kg body weight intramuscular. The outcome variables were sedation score (Richmond Agitation Sedation Scale), IV cannula acceptance (IV cannula Acceptance Score), and parental separation (Separation Score).&#x0D; Results: The groups were comparable in patient characteristics and hemodynamic parameters between the groups. Median (IQR) sedation score at 10 min were -1 (-2—0) and 0(-1—1) (p&lt; 0.001); mean parental separation scores were 3.76± 0.43 and 3.36±0.55 (p&lt; 0.001); IV cannula acceptance score were 3.73±0.44 and 4.53±7.27 (p= 0.001) in Group A and Group B respectively.&#x0D; Conclusion: Combination of dexmedetomidine and ketamine is superior to ketamine alone in terms of sedation at 15 min and ease of IV cannulation but comparable in terms of anxiolysis.

Dexmedetomidine alleviates propofol-induced neural injury in developing rats.

Propofol, a commonly used intravenous anesthetic, has been associated with neurodegeneration in the developing brain upon repeated exposure. Dexmedetomidine is an α2 adrenoceptor agonist that was previously reported to possess neuroprotective properties. Here, we confirmed the impacts of dexmedetomidine on propofol-induced neuroapoptosis and subsequent spatial learning and memory deficits in neonatal rats. We found that dexmedetomidine effectively mitigated propofol-induced spatial learning and memory impairments and improved aversive memory in developing rats. Dexmedetomidine reduced propofol-induced cell apoptosis in the hippocampus and modulated the mRNA expression of Bcl-2 and Bax. Additionally, dexmedetomidine attenuated the propofol-induced increase of inflammatory factors IL-6 and TNF-α. The reduced phosphorylation levels of Akt and CREB levels by propofol were re-activated by dexmedetomidine. In conclusion, our findings demonstrated that dexmedetomidine effectively mitigated propofol-induced cognitive and memory impairments in developing rats by modulating apoptosis and reducing inflammation via activating the Akt/CREB/BDNF signaling pathway. These findings suggest potential strategies to protect the developing brain from the adverse effects of anesthetics and improve patient care in pediatric anesthesia practice.

EFEKTIVITAS TEKNIK ANESTESI LOW FLOW DIBANDINGKAN TEKNIK ANESTESI INHALASI STANDAR PADA ANAK USIA 1-6 TAHUN YANG MENJALANI OPERASI DI PROF. DR. I.G.N.G. NGOERAH DENPASAR

Since the discovery of sevoflurane, it has been commonly used due to its many advantages, including its safety profile for pediatric anesthesia practice. However, currently no ideal recommendation for how much gas flow should be used during induction in children. High fresh gas flow (FGF) causes waste of anesthetic and oxygen gases, making it both uneconomical and environmentally polluting. To date, there have been very few studies on low FGF in children, so there is no best and efficient method for reducing the need for large amounts of induction gas. The aim of this study is to determine the effectiveness of the low low anesthesia (LFA) technique in reducing sevoflurane volume, induction time, and hemodynamics during surgery in children undergoing surgery. This is a case-control study conducted at Prof. Dr. I.G.N.G Ngoerah Hospital in Denpasar. Forty-six children aged 1 - 6 years underwent elective surgery and were anesthetized with sevoflurane and randomly divided into two groups: the case group using the low-flow anesthesia technique and the control group using the standard anesthesia technique. The case and control groups were statistically similar in terms of demographic data. However, the volume of sevoflurane used from the time of premedication to intubation was significantly different (p &gt; 0.05) between the two groups (35.5 ml vs 44.5 ml). The induction times were not significantly different (209s vs 201s, p&lt;0.05). Additionally, no significant difference was observed regarding hemodynamic stability during anesthesia.&#x0D; Keywords : anesthesia induction, hemodynamic stability, low flow anesthesia, sevoflurane

Trends in pediatric non-operating room anesthesia: Data from the National Anesthesia Clinical Outcomes Registry.

Modern pediatric anesthetic encounters occur in operating rooms and non-operating room settings. Most anesthesia providers have cared for children in radiology, endoscopy, and other interventional settings at some point in their training and career. There is an absence of published data on the frequency, timing, and demographics of these pediatric anesthesia encounters. The primary goal of our study is to present data spanning a variety of institutions and practice settings in the United States to define the percentage of non-operating room anesthetic encounters in children. We also set out to characterize the frequency of the most common procedures in the non-operating room setting within the United States. Using the National Anesthesia Clinical Outcomes Registry data from 2015-2019, we analyzed and reported data on current trends in non-operating room anesthesia including patient demographics, encounter setting, procedure type, and the time at which anesthetic encounters occurred. 2 236 788 pediatric anesthetic encounters (patient age <18 y.o.) were analyzed revealing that 22.7% of all pediatric anesthetics occur in non-operating room settings. Patients were more likely to have higher American Society of Anesthesiologists Physical Status classifications in the non-operating room anesthesia group. Gastroenterological suites are the most common setting reported for pediatric non-operating room anesthesia. Non-operating room anesthesia in the United States is a prominent segment of pediatric anesthetic practice. Pediatric patients encountered in the non-operating room setting have more comorbidities, though further studies are needed to characterize the implication of this finding.

Complication of Anesthesia in Children: A Prospective Observational Study

Background: Any anaesthetic procedure, either regional or general, has some potential for complications. For this reason, careful preoperative assessment and adequate planning of appropriate anesthetic are the cornerstones in safe pediatric anesthetic practice. But in Bangladesh, we have very limited research-based information regarding the complication of anaesthesia in children. Aim of the Study: The aim of this study was to assess the complications of anesthesia in children. Methods: This was a prospective observational study. The study was conducted in Department of Aneaesthesia, ICU &amp; Pain Medicine, Shaheed Suharawardy Medical College and Hospital, Dhaka, Bangladesh during the period from January 2018 to December 2018. In total 62 children, aged between 1 day and 15 years prepared for anesthesia associated surgery were selected as the study subjects. The incidence of intra-operative as well as post- anesthesia recovery room complications was recorded and analyzed. Data were analyzed and by using MS Excel and SPSS version 23.0 program as per necessity. Results: In this study, in analyzing the complications among the participants we observed that, bronchospam and bradycardia and hypotension were the most common intraoperative complications which were found in 11%, 10% and 8% cases respectively. On the other hand, tachycardia, prolonged unconsciousness and hypoventilation were found as the most common postoperative complications among the participants which were found in 19%, 10% and 8% cases respectively. Besides those complications some cases with restlessness, respiratory arrest, pain, shivering, hypertension, hemorrhage and laryngospasm were found in both the periods. Conclusion: Anesthesia-related morbidity and mortality can be minimized with early identification and prompt management of any complication. In this current study we observed that, preterm infants are major prone to develop respiratory complications because of using anesthesia.

Practice of Pediatric Spinal Anesthesia in a Country with Limited Means: Example of Togo

Introduction: The practice of spinal anesthesia in pediatric surgery is declining, especially in countries with limited means. What about in our context? Objective: To evaluate the practice of spinal anesthesia in pediatric surgery in Togo. Framework and method of study: This was a prospective study from November 2017 to May 2018 in pediatric surgery at CHU SO de Lomé, in the operating room and hospital ward of CHU Kara. The surgical, anesthesiological and evolutionary aspects of the patients were analyzed. Results: Sixty children were selected for the study who had an indication for sub-umbilical surgery. The male sex was predominant (73.3%). 47 (78.30%) patients were operated on for scheduled surgery. Hernia repair was the most performed surgical intervention (43.30%). The mean duration of the surgery was 78 ± 35.9 minutes. Most of the patients were ASA 1 (98.30%). The local anesthetic used was 0.5% isobaric Bupivacaine. Fentanyl was the predominant adjuvant (55%). The most widely used lumbar puncture needle was 25 Gauge with 75 millimeters in length (63.30%). Diazepam was the most widely used sedative (50%). The predominant spinal anesthesia protocol was spinal anesthesia alone (60%). Only one patient had hypotension (1.70%). Conclusion: The fairly satisfactory pediatric spinal anesthesia in Togo remains poorly performed. Its promotion involves the training of anesthesia practitioners and the strengthening of the technical platform.

Allaying Pediatric Preoperative Anxiety, Where are we Now? - A Nationwide Survey.

Preoperative anxiety (PA) in children is a common phenomenon associated with various negative patient outcomes. Allaying PA is accepted as a standard of care, but its use is not universal and often overlooked. This survey is designed to evaluate the nationwide current practice patterns and attitudes of anesthesiologists toward the practice of allaying PA in children. A questionnaire of 25 questions, including information on methods of relieving PA in children, reasons for noncompliance, and associated complications, was framed. It was circulated among members of the Indian Society of Anaesthesiologists through an online survey of Google Forms and manually. Four hundred and fifty anesthesiologists were surveyed. Responses were predominantly from anesthesiologists practicing in medical colleges across the country. Although 97% of the surveyed respondents practiced anxiety-relieving strategies, only 37% used it consistently. Seventy-three percent of anesthesiologists practiced both pharmacological and nonpharmacological techniques. The most common reason for avoiding premedication was an anticipated difficult airway (88%). Inadequate sedation was a commonly reported problem. Ninety-five percent of participants felt that PA-relieving strategies should be integral to pediatric anesthesia practice. The most common reason for not following these practices was an inadequate hospital infrastructure (67%). Ninety-seven percent of the participants believed that more awareness is required on this crucial perioperative issue. Only 37% of the surveyed anesthesiologists consistently used some form of PA-relieving strategy and the practice varied widely. Further improvement and team approach involving anesthesiologists, surgeons, and nurses is required to ensure the quality of pediatric PA-relieving services and establish it as a standard of care.

Practice of Pediatric Anesthesia in an Adult Operating Theater in Sub-Saharan Africa: Experience of the Essos Hospital Center in Yaounde (Cameroon)

Background: The aim of this study was to evaluate the practice of pediatric anesthesia in an adult operating theater in sub-Saharan Africa. Patients and Methods: This was an observational, prospective descriptive study that took place over a period of 12 months in the anesthesiology department of the Essos hospital center in Yaounde (Cameroon). Children &lt;15 years old, seen in anesthesia consultation and operated on for scheduled surgery during the above- mentioned period were included in the study. The variables studied were the variables studied were: the characteristics of the study population, the anesthetic and surgical data, as well as the patient's postoperative itinerary. Results: During the study period, 162 patients were included out of a total of 1205 patients operated on during the same period. The median age was 5 years, the sex ratio 1.8. ASA class 1 was the most represented (98.1%). The combination midazolam and atropine was the premedication of choice (87.1%). General anesthesia was the most practiced technique (96.3%). Induction of general anesthesia was inhalation in 69% of cases, sevoflurane was the hypnotic used in this indication. General anesthesia was performed by a senior anesthesiologist in 67.3% of children. The majority of surgical procedures belonged to otolaryngology surgery (57%). The electrocardiogram (ECG), blood pressure, SpO2 and heart rate constituted the main part of the intraoperative monitoring. Conclusion: In low-income countries, pediatric anesthesia is still performed by personnel who are not specialized in pediatric anesthesia. In order to improve the safety of children in the operating room, health policies must encourage training and specialization in this highly delicate area, which will make it possible to reduce perioperative infant morbidity and mortality.
