Kids Voices, the perioperative experience of emergency surgery from children's perspectives: A qualitative study

The study aimed to better understand children's emergency perioperative experience, a little researched topic. Current literature shows discrepancies between child and adult perceptions for the same healthcare experience. Acquisition of knowledge from the child's perspective can be utilized to improve perioperative care.

Complications associated with paediatric airway management during the COVID-19 pandemic: an international, multicentre, observational study

Respiratory adverse events in adults with COVID-19 undergoing general anaesthesia can be life-threatening. However, there remains a knowledge gap about respiratory adverse events in children with COVID-19. We created an international observational registry to collect airway management outcomes in children with COVID-19 who were having a general anaesthetic.

COVID-19 implications for pediatric anesthesia: Lessons learnt and how to prepare for the next pandemic

COVID-19 is mainly considered an “adult pandemic,” but it also has strong implications for children and consequently for pediatric anesthesia. Despite the lethality of SARS-CoV-2 infection being directly correlated with age, children have equally experienced the negative impacts of this pandemic.

Atelectasis and lung recruitment in pediatric anesthesia: An educational review

General anesthesia is associated with development of pulmonary atelectasis. Children are more vulnerable to the development and adverse effects of atelectasis. We review the physiology and risk factors for the development of atelectasis in pediatric patients under general anesthesia.

Clinical utility of preoperative pulmonary function testing in pediatrics

Perioperative respiratory adverse events pose a significant risk in pediatric anesthesia, and identifying these risks is vital. Traditionally, this is assessed using history and examination. However, the perioperative risk is multifactorial, and children with complex medical backgrounds such as chronic lung disease or obesity may benefit from additional objective preoperative pulmonary function tests.

Aerosolized drug delivery in awake and anesthetized children to treat bronchospasm

Bronchospasm is a common respiratory adverse event in pediatric anesthesia. First-line treatment commonly includes inhaled salbutamol. This review focuses on the current best practice to deliver aerosolized medications to awake as well as anesthetized pediatric patients and discusses the advantages and disadvantages of various administration techniques.

Anesthetic considerations in children with asthma

Due to the high prevalence of asthma and general airway reactivity, anesthesiologists frequently encounter children with asthma or asthma-like symptoms. This review focuses on the epidemiology, the underlying pathophysiology, and perioperative management of children with airway reactivity, including controlled and uncontrolled asthma.

Risk assessment and optimization strategies to reduce perioperative respiratory adverse events in pediatric anesthesia—Part 1 patient and surgical factors

Pediatric surgery cases are increasing worldwide. Within pediatric anesthesia, perioperative respiratory adverse events are the most common precipitant leading to serious complications.

Developmental respiratory physiology

Various developmental aspects of respiratory physiology put infants and young children at an increased risk of respiratory failure, which is associated with a higher rate of critical incidents during anesthesia.

Comparison of two measures of behavior change in children after day surgery

A contemporary, well-validated instrument for the measurement of behavior change in children after general anesthesia is lacking. The Post Hospitalization Behavior Questionnaire for Ambulatory Surgery (PHBQ-AS) has been developed as an updated version of the original Post Hospitalization Behavior Questionnaire (PHBQ) to better reflect the current patient population and modern anesthetic practices.

Procedural anesthesia and sedation for children undergoing diagnostic and medical procedures — A review of postprocedural pain, nausea, and vomiting by questionnaire-based survey

Sedation and anesthesia are widely used to relieve pain and ensure cooperation during elective diagnostic and medical procedures in the pediatric population. However, there is currently limited evidence about the recovery trajectory following deep sedation or general anesthesia for such procedures in children.

Direct versus video laryngoscopy with standard blades for neonatal and infant tracheal intubation with supplemental oxygen: a multicentre, non-inferiority, randomised controlled trial

Tracheal intubation in neonates and infants is a potentially life-saving procedure. Video laryngoscopy has been found to improve first-attempt tracheal intubation success and reduce complications compared with direct laryngoscopy in children younger than 12 months.

Perioperative intravenous lidocaine use in children

Perioperative pain management impacts patient morbidity, quality of life, and hospitalization cost. In children, it impacts not only the child, but the whole family. Adjuncts for improved perioperative analgesia continue to be sought to minimize adverse side effects associated with opioids and for those in whom regional or neuraxial anesthesia is not suitable.

Anaesthesia related mortality data at a Tertiary Pediatric Hospital in Western Australia

Anaesthesia related mortality in paediatrics is rare. There are limited data describing paediatric anaesthesia related mortality. This study determined the anaesthesia related mortality at a Tertiary Paediatric Hospital in Western Australia.

Sedation versus General Anesthesia for Tracheal Intubation in Children with Difficult Airways: A Cohort Study from the Pediatric Difficult Intubation Registry

Sedated and awake tracheal intubation approaches are considered safest in adults with difficult airways, but little is known about the outcomes of sedated intubations in children. The primary aim of this study was to compare the first-attempt success rate of tracheal intubation during sedated tracheal intubation versus tracheal intubation under general anesthesia. The hypothesis was that sedated intubation would be associated with a lower first-attempt success rate and more complications than general anesthesia.

Consumer research priorities for pediatric anesthesia and perioperative medicine

Consumer-driven research is increasingly being prioritized. Aim: Our aim was to partner with consumers to identify the top 10 research priorities for pediatric anesthesia and perioperative medicine. The ACORN (Anesthesia Consumer Research Network) was formed to collaborate with children and families across Australia.

Isoelectric Electroencephalography in Infants and Toddlers during Anesthesia for Surgery: An International Observational Study

Intraoperative isoelectric electroencephalography (EEG) has been associated with hypotension and postoperative delirium in adults. This international prospective observational study sought to determine the prevalence of isoelectric EEG in young children during anesthesia.

Remote after-care using smartphones: A feasibility study of monitoring children's pain with automated SMS messaging

Monitoring children's recovery postoperatively is important for routine care, research, and quality improvement. Although telephone follow-up is common, it is also time-consuming and intrusive for families. Using SMS messaging to communicate with families regarding their child's recovery has the potential to address these concerns. While a previous survey at our institution indicated that parents were willing to communicate with the hospital by SMS, data on response rates for SMS-based postoperative data collection is limited, particularly in pediatric populations.

Parents' perspectives towards paediatric confectionary masked medications: a qualitative study

The availability of age-appropriate, taste-masked oral solid medications for the paediatric population is currently inadequate. We have developed a novel chocolate-based drug delivery platform to taste-mask bitter drugs commonly utilised in the hospital setting, but there is limited evidence regarding parent's perspectives on these medications.

A randomised controlled trial of a novel tramadol chewable tablet: pharmacokinetics and tolerability in children

Tramadol is a bitter atypical opioid analgesic drug and is prescribed to treat postoperative pain in children. However, in many countries there is no licensed paediatric tramadol formulation available. We have formulated a novel chewable chocolate-based drug delivery system for the administration of tramadol to children.

Impact of airway and a standardized recruitment maneuver on CT chest imaging quality in a pediatric population: A retrospective review

When performing computerized tomography chest imaging in children, obtaining high quality, motion-free images is important in the accurate diagnosis of underlying pathology. General anesthesia is associated with the development of atelectasis, which can impair accurate diagnosis by obscuring or altering the appearance of the lung parenchyma or airways.

Impact of a revised postoperative care plan on pain and recovery trajectory following pediatric tonsillectomy

A previous cohort of adenotonsillectomy patients at our institution demonstrated moderate-severe post-tonsillectomy pain scores lasting a median (range) duration of 6 (0-23) days and postdischarge nausea and vomiting affecting 8% of children on day 1 following surgery. In this subsequent cohort, we evaluate the impact of changes to our discharge medication and parental education on post-tonsillectomy pain and recovery profile.

Lung ultrasound and atelectasis—The devil is in the details

Risk assessment and optimization strategies to reduce perioperative respiratory adverse events in Pediatric Anesthesia—Part 2: Anesthesia-related risk and treatment options

Perioperative respiratory adverse events are the most common cause of critical events in children undergoing anesthesia and surgery. While many risk factors remain unmodifiable, there are numerous anesthetic management decisions which can impact the incidence and impact of these events, especially in at-risk children.

The impact of surgical cancellations on children, families, and the health system in an Australian paediatric tertiary referral hospital

Reasons for elective surgery cancelations and their impact vary from one institution to another. Cancelations have emotional and financial implications for patients and their families. Our service has a particularly broad and geographically diverse patient population; hence, we sought to examine these impacts in our service.

Gender Balance in Anesthesiology: Is a Change of Societal Mindset Needed?

With great interest, we are following the discussion on Speaker Gender Representation and Trends in Authorship. While it is indeed very popular and important to look at speaker representation, authorship, or board membership by gender, the underlying reasons for the unequal gender representation are not as easy to determine. Counting numbers on panels or boards may also not add up to real representation.

Perioperative pediatric tonsillectomy analgesia: A single-center review of practice and cost-effectiveness analysis

Tonsillectomy is one of the most common pediatric surgeries and results in considerable postoperative pain. Insufficiently managed pain is costly, risks physiological and psychological consequences with multi-modal analgesia widely recommended to minimize opioid-based agents. We determined adherence to multi-modal analgesia guidelines and assessed cost-effectiveness. We undertook a cross-sectional cohort study at a tertiary pediatric institution in Perth, Western Australia, retrospectively identifying selected patients undergoing tonsillectomy over two discrete periods of 6-week duration.

An observational study of hypoactive delirium in the post-anesthesia recovery unit of a pediatric hospital

Hypoactive delirium is present when an awake child is unaware of his or her surroundings, is unable to focus attention, and appears quiet and withdrawn. This condition has been well-described in the intensive care setting but has not been extensively studied in the immediate post-anesthetic period. The aim was to determine if hypoactive emergence delirium occurs in the recovery unit of a pediatric hospital, and if so, what proportion of emergence delirium is hypoactive in nature.

Prenatal Exposure to General Anesthesia and Childhood Behavioral Deficit

Exposure to surgery and anesthesia in early childhood has been found to be associated with an increased risk of behavioral deficits. While the US Food and Drug Administration (FDA) has warned against prenatal exposure to anesthetic drugs, little clinical evidence exists to support this recommendation. This study evaluates the association between prenatal exposure to general anesthesia due to maternal procedures during pregnancy and neuropsychological and behavioral outcome scores at age 10.

A comparison of videolaryngoscopy using standard blades or non-standard blades in children in the Paediatric Difficult Intubation Registry

The design of a videolaryngoscope blade may affect its efficacy. We classified videolaryngoscope blades as standard and non-standard shapes to compare their efficacy performing tracheal intubation in children enrolled in the Paediatric Difficult Intubation Registry.

The role of fit testing N95/FFP2/FFP3 masks: a narrative review

For healthcare workers performing aerosol-generating procedures during the COVID-19 pandemic, well fitted filtering facepiece respirators, for example, N95/FFP2 or N99/FFP3 masks, are recommended as part of personal protective equipment. In this review, we evaluate the role of fit checking and fit testing of respirators, in addition to airborne protection provided by respirators. Filtering facepiece respirators are made of material with sufficient high filter capacity to protect against airborne respiratory viruses.

Without training, they lacked knowledge. Without knowledge, they lacked confidence. Without confidence, they lacked victory (Julius Caesar)

HPLC-UV assay of tramadol and O-desmethyltramadol in human plasma containing other drugs potentially co-administered to participants in a paediatric population pharmacokinetic study

Multimodal analgesia is employed in paediatric pain management to maximise analgesia and minimise side effects. Tramadol is dosed at 1–1.5 mg/kg to treat severe pain in children but the assay for tramadol in plasma samples for pharmacokinetic and toxicology studies does not often consider concurrently administered medications.

Pediatric Airway Management in Times of COVID-19-a Review of the Evidence and Controversies

This review summarizes and provides a comprehensive narrative synthesis of the current evidence on pediatric airway management during the COVID-19 pandemic.

Pediatric airway management

Children are at risk of severe hypoxemia in the perioperative period owing to their unique anatomy and physiology. Safe and effective airway management strategies are therefore key to the practice of pediatric anesthesia. The goal of this review is to highlight recent publications (2019-2021) aimed to advance pediatric airway safety and to highlight a proposed simple, pediatric-specific, universal framework to guide clinical practice.

A survey of the global impact of COVID-19 on the practice of pediatric anesthesia: A study from the pediatric anesthesia COVID-19 Collaborative Group

Pediatric anesthesiology has been greatly impacted by COVID-19 in the delivery of care to patients and to the individual providers. With this study, we sought to survey pediatric centers and highlight the variations in care related to perioperative medicine during the COVID-19 pandemic, including the availability of protective equipment, the practice of pediatric anesthesia, and economic impact.

An assessment of opioids on respiratory depression in children with and without obstructive sleep apnea

Obstructive sleep apnea is a risk factor for respiratory depression following opioid administration as well as opioid-induced hyperalgesia. Little is known on how obstructive sleep apnea status is associated with central ventilatory depression in pediatric surgical patients given a single dose of fentanyl.

Carbon dioxide monitoring in children—A narrative review of physiology, value, and pitfalls in clinical practice

Continuous capnography has been recognised as an essential monitoring device in all anesthetized patients, despite which airway device is in use, regardless of their location, as a measure to improve patient safety. Capnography is the non-invasive measurement of a sample of the exhaled carbon dioxide which has multiple clinical uses including as a method to confirm placement of a tracheal tube and/or to assess ventilation, perfusion and metabolism.

Assessment of different techniques for the administration of inhaled salbutamol in children breathing spontaneously via tracheal tubes, supraglottic airway devices, and tracheostomies

Perioperative respiratory adverse events account for a third of all perioperative cardiac arrests, with bronchospasm and laryngospasm being most common. Standard treatment for bronchospasm is administration of inhaled salbutamol, via pressurized metered dose inhaler. There is little evidence on the best method of attaching the pressurized metered dose inhaler to the artificial airway during general anesthesia. The aim of this study is to investigate the best method to deliver aerosolized salbutamol via pressurized metered dose inhaler to the lungs of an anesthetized child.

Fit testing of N95 or P2 masks to protect health care workers

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has many similarities to severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). While reported morbidity and mortality from COVID-19 are lower than from SARS and MERS, many health care workers have been infected (up to 15% of health care workers in Victoria).

Anaesthesia, pain and recovery profiles in children following dental extractions

The aim of this prospective cohort study was to describe the anaesthetic practices, rates of postoperative pain and the recovery trajectory of children having urgent dental extractions at our institution.

The plural of anecdote is not data, please mind the gap

The COVID-19 pandemic introduced challenges to everyone in society but particularly so to every aspect of medical practice. It is bewildering how quickly the profession has had to respond to rapidly changing clinical landscape. Our well-established methods involve collecting and analyzing data to generate an evidence base which is then disseminated and implemented into routine clinical practice.

What’s inside the box? Or shall we think outside the box?

With the deadly and highly transmissible SARS-CoV-2 virus causing the COVID-19 pandemic, there is global concern about the danger of contaminating healthcare workers (HCW), particularly during airway management of infected patients.
