The use of honey in the perioperative care of tonsillectomy patients-A narrative review.

Tonsillectomy is one of the most common surgical procedures in childhood. While generally safe, it often is associated with a difficult early recovery phase with poor oral intake, dehydration, difficult or painful swallowing, postoperative bleeding, infection and/or otalgia. Better pain management and the availability of more child friendly medications are within the top consumer priorities in perioperative medicine, highlighting the importance of alternative pain treatments. This review focuses on the potential role of honey in the postoperative setting, its effects, and mechanisms of action. While the application of honey post-tonsillectomy may offer analgesic and healing benefits, it may also reduce postoperative bleeding. A systematic search was carried out using the search terms honey, tonsillectomy. Filters were applied to human studies and English. No other search terms were used or age filters applied to yield a broader range of results. Seven pediatric, four adult, and two studies of mixed pediatric and adult patients with sample sizes ranging from 8 to 52 patients were included in this review. Effect sizes ranged from small to huge across the studies. While the application of honey post-tonsillectomy may offer analgesic and healing benefits, it may also reduce postoperative bleeding. However, while there are potential benefits based on the chemical composition of honey, the current literature is of variable quality and there is need for high quality clinical trials.

Patient positioning and its impact on perioperative outcomes in children: A narrative review.

Patient positioning interacts with a number of body systems and can impact clinically important perioperative outcomes. In this educational review, we present the available evidence on the impact that patient positioning can have in the pediatric perioperative setting. A literature search was conducted using search terms that focused on pediatric perioperative outcomes prioritized by contemporary research in this area. Several key themes were identified: the effects of positioning on respiratory outcomes, cardiovascular outcomes, enteral function, patient and carer-centered outcomes, and soft issue injuries. We encountered considerable heterogeneity in research in this area. There may be a role for lateral positioning to reduce respiratory adverse outcomes, head elevation for intubation and improved oxygenation, and upright positioning to reduce peri-procedural anxiety.

Effect of different lung recruitment strategies and airway device on oscillatory mechanics in children under general anaesthesia.

BACKGROUND: Atelectasis has been reported in 68 to 100% of children undergoing general anaesthesia, a phenomenon that persists into the recovery period. Children receiving recruitment manoeuvres have less atelectasis and fewer episodes of oxygen desaturation during emergence. The optimal type of recruitment manoeuvre is unclear and may be influenced by the airway device chosen. OBJECTIVE: We aimed to investigate the different effects on lung mechanics as assessed by the forced oscillation technique (FOT) utilising different recruitment strategies: repeated inflations vs. one sustained inflation and different airway devices, a supraglottic airway device vs. a cuffed tracheal tube. DESIGN: Pragmatic enrolment with randomisation to the recruitment strategy. SETTING: We conducted this single-centre trial between February 2020 and March 2022. PARTICIPANTS: Seventy healthy patients (53 boys) aged between 2 and 16 years undergoing general anaesthesia were included. INTERVENTIONS: Forced oscillations (5 Hz) were superimposed on the ventilator waveform using a customised system connected to the anaesthesia machine. Pressure and flow were measured at the inlet of the airway device and used to compute respiratory system resistance and reactance. Measurements were taken before and after recruitment, and again at the end of surgery. MAIN OUTCOME MEASURES: The primary endpoint measured is the change in respiratory reactance. RESULTS: Statistical analysis (linear model with recruitment strategy and airway device as factors) did not show any significant difference in resistance and reactance between before and after recruitment. Baseline reactance was the strongest predictor for a change in reactance after recruitment: prerecruitment Xrs decreased by mean (standard error) of 0.25 (0.068) cmH 2 O s l -1 per  1 cmH 2 O -1  s l -1 increase in baseline Xrs ( P  < 0.001). After correcting for baseline reactance, the change in reactance after recruitment was significantly lower for sustained inflation compared with repeated inflation by mean (standard error) 0.25 (0.101) cmH 2 O ( P  = 0.0166). CONCLUSION: Although there was no significant difference between airway devices, this study demonstrated more effective recruitment via repeated inflations than sustained inflation in anaesthetised children.

Predicting obstructive sleep apnoea and perioperative respiratory adverse events in children: role of upper airway collapsibility measurements.

BACKGROUND: Obstructive sleep apnoea (OSA) and perioperative respiratory adverse events are significant risks for anaesthesia in children undergoing adenotonsillectomy. Upper airway collapse is a crucial feature of OSA that contributes to respiratory adverse events. A measure of upper airway collapsibility to identify undiagnosed OSA can help guide perioperative management. We investigated the utility of pharyngeal closing pressure (PCLOSE) for predicting OSA and respiratory adverse events. METHODS: Children scheduled for elective adenotonsillectomy underwent in-laboratory polysomnography 2-12 weeks before surgery. PCLOSE measurements were obtained while the child was anaesthetised and breathing spontaneously just before surgery. Logistic regression was used to assess the predictive performance of PCLOSE for detecting OSA and perioperative respiratory adverse events after adjusting for potential covariates. RESULTS: In 52 children (age, mean [standard deviation] 5.7 [1.8] yr; 20 [38%] females), airway collapse during PCLOSE was observed in 42 (81%). Of these, 19 of 42 (45%) patients did not have OSA, 15 (36%) had mild OSA, and eight (19%) had moderate-to-severe OSA. All 10 children with no evidence of airway collapse during the PCLOSE measurements did not have OSA. PCLOSE predicted moderate-to-severe OSA (odds ratio [OR] 1.71; 95% confidence interval [CI]: 1.2-2.8; P=0.011). All children with moderate-to-severe OSA could be identified at a PCLOSE threshold of -4.0 cm H2O (100% sensitivity), and most with no or mild OSA were ruled out (64.7% specificity; receiver operating characteristic/area under the curve=0.857). However, there was no significant association between respiratory adverse events and PCLOSE (OR 1.0; 95% CI: 0.8-1.1; P=0.641). CONCLUSIONS: Measurement of PCLOSE after induction of anaesthesia can reliably identify moderate or severe OSA but not perioperative respiratory adverse events in children before adenotonsillectomy.

A review of pediatric fasting guidelines and strategies to help children manage preoperative fasting.

Fasting for surgery is a routine step in the preoperative preparation for surgery. There have however been increasing concerns with regard to the high incidence of prolonged fasting in children, and the subsequent psycho-social distress and physiological consequences that this poses. Additionally, the past few years have yielded new research that has shown significant inter-individual variation in gastric emptying regardless of the length of the fast, with some patients still having residual gastric contents even after prolonged fasts. Additionally, multiple large-scale studies have shown no long-term sequalae from clear fluid aspiration, although two deaths from aspiration have been reported within the large Wake Up Safe cohort. This has led to a change in the recommended clear fluid fasting times in multiple international pediatric societies; similarly, many societies continue to recommend traditional fasting times. Multiple fasting strategies exist in the literature, though these have mostly been studied and implemented in the adult population. This review hopes to summarize the recent updates in fasting guidelines, discuss the issues surrounding prolonged fasting, and explore potential tolerance strategies for children.

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. The use of ketamine and alpha agonists may be useful in these settings but have noted adverse effects including hallucinations, hemodynamic instability, and excessive sedation. One alternative is intravenous lidocaine. Despite its off-label use, intravenous lidocaine has demonstrated anti-neuropathic, anti-hyperalgesic, and anti-inflammatory actions and is an emerging technique. Multiple studies in adults have demonstrated beneficial effects of perioperative intravenous lidocaine including improved perioperative analgesia with reduced postoperative opioid use, improved gastrointestinal function, earlier mobilization, and reduction in hospital length of stay. Despite the limited pediatric literature, some of these findings have been replicated. Large-scale trials providing evidence for the pediatric pharmacokinetics and high-quality safety data with respect to intravenous lidocaine are still however lacking. To date, dose ranges studied in the pediatric population have not been associated with serious side effects and current data suggests perioperative intravenous lidocaine in a subgroup of pediatric surgical patients seems well-tolerated and beneficial.

Consumer research priorities for pediatric anesthesia and perioperative medicine.

BACKGROUND: 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. METHODS: A prospective online survey was developed to generate research ideas from consumers. The survey was developed in Qualtrics, a survey research platform. Consumers were invited to participate through poster advertising, social media posts, via consumer networks at participating hospitals and in addition 35 national consumer/patient representative organizations were approached. We also conducted a similar idea generating survey for clinicians through email invitation and via Twitter. A second round of surveys was conducted to prioritize the long list of research questions and a shortlist of priorities developed. A single consensus meeting was held, and a final consensus list of top 10 priorities emerged. RESULTS: A total of 281 research ideas were submitted between 356 consumers in the idea generating survey and from four consumer/patient representative groups. Seventy-five clinicians responded to the clinician idea generation survey. This was consolidated into 20 research ideas/themes for the second survey for each group. 566 responses were received to the consumer prioritization top 10 survey and 525 responses to the clinician survey. The consensus meeting produced the final 10 consumer research priorities. CONCLUSION: This study has given Australian consumers the opportunity to shape the anesthesia and perioperative medicine research agenda for pediatric patients both nationally and internationally.

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

BACKGROUND: 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. The authors hypothesized that the prevalence of isoelectric events would be common worldwide and associated with certain anesthetic practices and intraoperative hypotension. METHODS: Fifteen hospitals enrolled patients age 36 months or younger for surgery using sevoflurane or propofol anesthetic. Frontal four-channel EEG was recorded for isoelectric events. Demographics, anesthetic, emergence behavior, and Pediatric Quality of Life variables were analyzed for association with isoelectric events. RESULTS: Isoelectric events occurred in 32% (206 of 648) of patients, varied significantly among sites (9 to 88%), and were most prevalent during pre-incision (117 of 628; 19%) and surgical maintenance (117 of 643; 18%). Isoelectric events were more likely with infants younger than 3 months (odds ratio, 4.4; 95% CI, 2.57 to 7.4; P < 0.001), endotracheal tube use (odds ratio, 1.78; 95% CI, 1.16 to 2.73; P = 0.008), and propofol bolus for airway placement after sevoflurane induction (odds ratio, 2.92; 95% CI, 1.78 to 4.8; P < 0.001), and less likely with use of muscle relaxant for intubation (odds ratio, 0.67; 95% CI, 0.46 to 0.99; P = 0.046]. Expired sevoflurane was higher in patients with isoelectric events during preincision (mean difference, 0.2%; 95% CI, 0.1 to 0.4; P = 0.005) and surgical maintenance (mean difference, 0.2%; 95% CI, 0.1 to 0.3; P = 0.002). Isoelectric events were associated with moderate (8 of 12, 67%) and severe hypotension (11 of 18, 61%) during preincision (odds ratio, 4.6; 95% CI, 1.30 to 16.1; P = 0.018) (odds ratio, 3.54; 95% CI, 1.27 to 9.9; P = 0.015) and surgical maintenance (odds ratio, 3.64; 95% CI, 1.71 to 7.8; P = 0.001) (odds ratio, 7.1; 95% CI, 1.78 to 28.1; P = 0.005), and lower Pediatric Quality of Life scores at baseline in patients 0 to 12 months (median of differences, -3.5; 95% CI, -6.2 to -0.7; P = 0.008) and 25 to 36 months (median of differences, -6.3; 95% CI, -10.4 to -2.1; P = 0.003) and 30-day follow-up in 0 to 12 months (median of differences, -2.8; 95% CI, -4.9 to 0; P = 0.036). Isoelectric events were not associated with emergence behavior or anesthetic (sevoflurane vs. propofol). CONCLUSIONS: Isoelectric events were common worldwide in young children during anesthesia and associated with age, specific anesthetic practices, and intraoperative hypotension.

Penicillin allergy SHACK: Survey of hospital and community knowledge.

AIM: Penicillin allergy accounts for the majority of all reported adverse drug reactions in adults and children. Foregoing first-line antibiotic therapy due to penicillin allergy label is associated with an increased prevalence of infections by resistant organisms and longer hospitalisation. Clinician awareness of allergy assessment, referral indications, management of allergy and anaphylaxis is therefore vital but globally lacking. We aim to assess the knowledge of penicillin allergy, assessment and management in Western Australian health professionals. METHODS: An anonymous survey was distributed to pharmacists, nurses and physicians within Western Australian paediatric and adult Hospitals, Community and General Practice. RESULTS: In total, 487/611 were completed and included in the statistical analysis. Only 62% (301/487) of respondents routinely assessed for patient medication allergies. Of those who assessed allergy, 9% (28/301) of respondents met the Australian standards for allergy assessment. Only 22% (106/487) of participants correctly cited all indications for management with adrenaline in anaphylaxis to antibiotics and 67% (197/292) of physicians rarely or never referred to an allergy service. Paediatric clinicians had an increased understanding of allergy assessment and anaphylaxis management. Recent penicillin allergy education within a 5-year period led to significant improvements in allergy knowledge. CONCLUSION: Overall, knowledge, assessment and management of penicillin allergies among practitioners in Western Australia are currently inadequate in adults and paediatric clinicians to provide safe and effective clinical care. The implementation of a targeted education program for WA health professionals is urgently required and is expected to improve clinician knowledge and aid standardised penicillin assessment (de-labelling) practices.

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. We discuss the clinical significance of atelectasis, the use and value of recruitment maneuvers, and other techniques available to minimize lung collapse. This review demonstrates the value of a recruitment maneuver, maintaining positive end-expiratory pressure (PEEP) until extubation and lowering FiO2 where possible in the daily practice of the pediatric anesthetist.

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

INTRODUCTION: 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. Recruitment maneuvers, performed by anesthesiologists, can be used to effectively re-expand atelectatic lung. METHODS: The computerized tomography chest imaging in 44 children aged between 2 months and 7 years, undergoing serial imaging for monitoring of cystic fibrosis, were reviewed and graded for atelectasis. The first scan performed on each child was performed with a supraglottic airway device and a non-standardized recruitment maneuver. The second scan on each child was performed with a cuffed endotracheal tube and a standardized recruitment maneuver. RESULTS: When a supraglottic airway device and a non-standardized recruitment maneuver were used, 77% of patients demonstrated atelectasis of any degree on their computerized tomography chest imaging, compared with only 39% when a cuffed endotracheal tube and standardized recruitment maneuver were used. The percentage of computerized tomography chest scans that were scored acceptable (with either a total combined lung atelectasis score of 0 or 1) improved from 37% to 75% when a cuffed endotracheal tube and standardized recruitment maneuver were used. In particular, the mean atelectasis score for both lungs improved from 2.91 (SD ± 2.6) to 1.11 (SD ± 1.9), with a mean difference of 1.8 (95% CI 0.82-2.77; p: .0004). CONCLUSION: The use of a cuffed endotracheal tube and a standardized recruitment maneuver is an effective way to reduce atelectasis as a result of general anesthesia. Anesthesiologists can actively contribute toward improved image quality through their choice of airway and recruitment maneuver.

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

BACKGROUND: 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. AIMS: We conducted a feasibility study with 50 completed pain profiles obtained from patients at Perth Children's Hospital to examine response rates. METHODS: We collected and classified daily average pain (0-10 parent proxy score) on each day after tonsillectomy until pain-free for two consecutive days. RESULTS: We enrolled 62 participants and recorded 50 (81%) completed pain profiles, with 711 (97.9%) of 726 requests for a pain score receiving a response. Two families (3%) opted out of the trial, and 10 (16%) were lost to follow-up. Responses received were classified automatically in 92% of cases. No negative feedback was received, with a median (range) satisfaction score of 5 on a 5-point Likert scale (1 = very unhappy, 5 = very happy). CONCLUSIONS: This methodology is likely to generalize well to other simple clinical questions and produce good response rates in further similar studies. We expect SMS messaging to permit expanded longitudinal data collection and broader investigation into patient recovery than previously feasible using telephone follow-up at our institution.

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

BACKGROUND: 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. AIMS: The primary aim was to describe the severity and duration of pain, nausea, and vomiting after common diagnostic and medical procedures. Secondary outcomes include return to baseline functioning and incidence of medical re-presentation. METHODS: Recruitment was achieved postprocedurally by telephone interview with parents or legal guardians of patients who underwent botox injection, bronchoscopy, either or both a colonoscopy or upper gastrointestinal endoscopy, or MRI scan. Daily pain scores, nausea and vomiting, administration of at-home analgesia, and any adverse events requiring medical attention were obtained. Children were followed until pain completely resolved and baseline activity resumed. RESULTS: A total of 307 patients were included (50 botox injection, bronchoscopy and MRI; 48 colonoscopy, 58 upper gastrointestinal endoscopy, 51 colonoscopy plus upper gastrointestinal endoscopy). Parental-rated pain scores peaked on day of procedure across all groups and decreased over time, with most children resuming normal activity within 1 day postprocedure. Pain was mostly mild and resolved quickly in botox injection (10% moderate to severe and 22% mild), bronchoscopy (8% and 10%, respectively), and MRI (2% mild) patients. Combined upper gastrointestinal endoscopy and colonoscopy was associated with greatest pain severity (29% moderate to severe and 20% mild). Highest rates of nausea and/or vomiting were observed in colonoscopy (23%), upper gastrointestinal endoscopy (28%), and combined procedure groups (20%). At-home simple analgesia was administered in 21% of patients. Unplanned medical re-presentations were infrequent across all groups. CONCLUSION: This study demonstrates that the recovery trajectory following procedural sedation and anesthesia is short, with minimal requirement for additional medical attention. These findings will aid in alleviating parental anxiety and encourage utilization of regular simple analgesia.

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. Ongoing research continues to improve our understanding of both the influence of risk factors and the effect of specific interventions. This review discusses anesthesia risk factors and outlines strategies to reduce the rate and impact of perioperative respiratory adverse events with a chronologic based inquiry into anesthetic management decisions through the perioperative period from premedication to postoperative disposition.

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. They can have intraoperative impact on the surgical procedure itself, lead to premature case termination and in addition may have postoperative impact resulting in longer hospitalization stays and costs. Although most perioperative respiratory adverse events can be promptly detected and managed, and will not lead to any sequelae, the risk of life-threatening progression remains. The incidence of respiratory adverse events increases in children with comorbid respiratory and/or nonrespiratory illnesses. Optimized perioperative patient care, risk-stratified care level choice, and practitioners with appropriate training allow for risk mitigation. This review will discuss patient and surgical risk factors with a focus on common patient comorbid illnesses and review scoring systems to quantify risk.

First-attempt success rate of video laryngoscopy in small infants (VISI): a multicentre, randomised controlled trial.

BACKGROUND: Orotracheal intubation of infants using direct laryngoscopy can be challenging. We aimed to investigate whether video laryngoscopy with a standard blade done by anaesthesia clinicians improves the first-attempt success rate of orotracheal intubation and reduces the risk of complications when compared with direct laryngoscopy. We hypothesised that the first-attempt success rate would be higher with video laryngoscopy than with direct laryngoscopy. METHODS: In this multicentre, parallel group, randomised controlled trial, we recruited infants without difficult airways abnormalities requiring orotracheal intubation in operating theatres at four quaternary children's hospitals in the USA and one in Australia. We randomly assigned patients (1:1) to video laryngoscopy or direct laryngoscopy using random permuted blocks of size 2, 4, and 6, and stratified by site and clinician role. Guardians were masked to group assignment. The primary outcome was the proportion of infants with a successful first attempt at orotracheal intubation. Analysis (modified intention-to-treat [mITT] and per-protocol) used a generalised estimating equation model to account for clustering of patients treated by the same clinician and institution, and adjusted for gestational age, American Society of Anesthesiologists physical status, weight, clinician role, and institution. The trial is registered at ClinicalTrials.gov, NCT03396432. FINDINGS: Between June 4, 2018, and Aug 19, 2019, 564 infants were randomly assigned: 282 (50%) to video laryngoscopy and 282 (50%) to direct laryngoscopy. The mean age of infants was 5·5 months (SD 3·3). 274 infants in the video laryngoscopy group and 278 infants in the direct laryngoscopy group were included in the mITT analysis. In the video laryngoscopy group, 254 (93%) infants were successfully intubated on the first attempt compared with 244 (88%) in the direct laryngoscopy group (adjusted absolute risk difference 5·5% [95% CI 0·7 to 10·3]; p=0·024). Severe complications occurred in four (2%) infants in the video laryngoscopy group compared with 15 (5%) in the direct laryngoscopy group (-3·7% [-6·5 to -0·9]; p=0·0087). Fewer oesophageal intubations occurred in the video laryngoscopy group (n=1 [<1%]) compared with in the direct laryngoscopy group (n=7 [3%]; -2·3 [-4·3 to -0·3]; p=0·028). INTERPRETATION: Among anaesthetised infants, using video laryngoscopy with a standard blade improves the first-attempt success rate and reduces complications.

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

BACKGROUND: 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. METHODS: We identified families with procedural cancelations and administered a telephone questionnaire. Survey items included the reason for and timing of cancelation, how the family was informed, the mode of transport and distance traveled to the hospital, associated leave from work, expenses, whether the child was required to fast, missed school, as well as the child's and parent's emotional responses to the cancelation, along with overall parental satisfaction with how the cancelation was handled. RESULTS: During our study period, a total of 7870 procedures were booked. 6734 (86%) of these were completed and 1136 (14%) were canceled, with 6% canceled on the day of surgery. In 750 (66%) of these cancelations, families were successfully contacted by telephone and agreed to participate. Of these 305 (41%) cancelations were family-initiated and 444 (59%) were hospital-initiated, with these hospital-initiated cancelations occurring closer to scheduled surgery. The most common cause of cancelation was that the child could not undergo the procedure due to illness (22%) or being unable attend the hospital (14%). The greatest disruption to families and children occurred when procedures were canceled late, particularly when the cancelation occurred on the day of the planned procedure.

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

BACKGROUND: 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. METHODS: In this follow-on, prospective observational cohort study, all patients undergoing tonsillectomy at our institution during the study period were discharged with standardized analgesia. Parents received a revised education package and a medication diary which were not provided to the previous cohort. Pain scores, rates of nausea and vomiting, medication usage and unplanned representation rates were collected by telephone from parents. RESULTS: Sixty-nine patients were recruited. Moderate-severe pain lasted a median (range) of 5 (0-12) days. Twenty-nine (42%) had pain scores ≥4/10 beyond postoperative day 7. By postoperative day 5, only 37 (53%) parents continued to administer regular analgesia. The median number of oxycodone doses used was 5 (0-22), and only 28 (41%) parents had disposed of leftover oxycodone within 1 month of surgery. Twenty-four (35%) patients experienced nausea or vomiting postdischarge. The median (range) time for return to normal activities was 6 (0-14) days. Thirty-two/sixty-nine (46%) patients had unplanned medical representations. Most occurred between postoperative day 5 and 7. Pain contributed to 16 (35%) representations. CONCLUSIONS: Despite extensive changes to our discharge protocols parents continued to report a prolonged period of pain, post operative nausea and vomiting, and behavioral changes. Further work is required to examine barriers to compliance with simple analgesia and education in appropriate methods of opioid disposal.

An update on allergy and anaphylaxis in pediatric anesthesia.

Childhood allergy is common, and increasing. Many children are incorrectly labeled as having allergy or adverse drug reactions. This can pose a dilemma for anesthetists and lead to a change in practice or drug selection. We review the pathophysiology of hypersensitivity reactions and the implications for anesthesia of food allergy, atopy, and family history of allergy in children. The epidemiology of anaphylaxis is discussed. We discuss the common triggers of perioperative anaphylaxis in children and explore emerging triggers including chlorhexidine and sugammadex. Accurate data on pediatric perioperative anaphylaxis is limited worldwide, with marked geographic variation. This highlights the need for accurate local, district and/or nationwide incident reporting. The clinical features, diagnosis, and management of anaphylaxis under anesthesia are discussed. We review the process of expert allergy testing following a suspected case of anaphylaxis to guide future safe anesthesia administration. The preoperative consultation is an opportunity for referral for allergy testing to allow de-labeling. This has the potential for improved antibiotic stewardship and more effective treatment with first-line therapeutic agents.

Allergy alerts - The incidence of parentally reported allergies in children presenting for general anesthesia.

BACKGROUND AND AIM: Pediatric patients increasingly report allergies, including allergies to food and medications. We sought to determine the incidence and, nature of parent-reported allergies in children presenting for surgery and its significance for anesthetists. METHODS: We prospectively collected data on admissions through our surgical admission unit over a 2-month period at a pediatric tertiary care teaching hospital. Data collected included patient demographics, history of atopy, with more comprehensive information collected if an allergy was reported. A clinical immunologist and an anesthetist reviewed the documentation of all patients reporting an allergy. RESULTS: We reviewed 1001 pediatric patients, 158 (15.8%) patients with parent-reported allergies; to medications/drugs (n = 73), food (n = 66), environmental allergens (dust/grasses, n = 35), tapes/dressings (n = 27), latex (n = 4), and venom (eg, bee, wasp, n = 9). Forty-one patients reported antibiotic allergies, with Beta-lactam antibiotics being the most common, with the majority presenting with rash alone (57%). Ten patients reported allergies to nonsteroidal anti-inflammatory drugs and eight to opioids. Twenty-four patients reported egg and/or peanut allergy. Only 3/1001 (0.3%) patients were deemed to have evidence of likely IgE-mediated drug allergy. Of the reported allergies, only 60 (38.2%) had been investigated prior, most likely to be followed up were food (53%) and environmental allergies (44.4%). Only 4/73 (5.5%) reported medication allergies had further follow-up. Just four patients (0.4% of the entire cohort) had drug sensitivities/allergies that were likely to majorly alter anesthesia practice. CONCLUSION: Only the minority of parent-reported allergies in pediatric surgical patients were specialist confirmed and likely to be clinically relevant. Self-reported food allergy is commonly specialist verified whereas reactions to medications were generally not. Over-reporting of allergies is increasingly common and limits clinician choice of medications. Better education of patients and their families and more timely verification or dismissal of parent-reported reactions is urgently needed.
