RESUMEN
Wake Up Safe is a patient safety organization consisting of 40 institutions with a mission to improve the processes of care and outcomes for newborns, infants, and children having anesthesia for surgery and medical procedures. It was recognized that the level of quality improvement (QI), knowledge, and experience varied greatly between member institutions. In Fiscal Year 2015, the group's leadership created a subcommittee on QI and education in efforts to provide member institutions with the skills and resources to use QI methodology to improve care at their own institution. This subcommittee developed a program to improve members' knowledge in safety analytics and QI science and to help members implement change in their own institutions. This review describes the development and implementation of this initiative. As a result of this initiative, significant progress was made improving the QI capability of the collaborative over a two-year period. This educational and support program included workshops, an online discussion forum, site visits, and project presentations.

SummaryThis retrospective study aimed to determine the incidence of and factors associated with peripheral intravenous extravasation in paediatric patients in the intraoperative setting. We conducted a retrospective study of 56,777 patients who underwent general anaesthesia and had peripheral intravenous catheter placement at Cincinnati Children's Hospital between 1 January 2015 and 1 January 2017. Data collected included age, American Society of Anesthesiologists Physical Status Classification, catheter site, number of cannulation attempts, ultrasound use for cannulation, surgery duration, and surgery class. Primary outcome was peripheral intravenous extravasation using an extravasation assessment tool. Some 64,814 peripheral venous catheters were placed in patients undergoing general anaesthesia. Significant extravasation was documented in 40 catheters with an estimated incidence of 1 in 1620 venous catheters (0.06%). Of those 40 catheters, 47.5% (n = 19) were placed using ultrasound and 37.5% (n = 15) required more than one cannulation attempt. In multivariable analysis, peripheral intravenous catheter extravasation was associated with American Society of Anesthesiologists Physical Status Classification (3, 4, 5) versus (1, 2) (odds ratio 2.42 (95% CI 1.08 to 5.41)), inpatient versus outpatient surgeries (odds ratio 2.99 (95% CI 1.31 to 6.81)), and intravenous catheters placed with ultrasound guidance (odds ratio 8.01 (95% CI 4.12 to 15.57)). Our study identified factors associated with intraoperative peripheral intravenous extravasation, and will help develop mitigation strategies to minimise harm to patients.

BACKGROUND: Auditory brainstem response (ABR) testing is considered to be relatively resistant to effects of volatile anesthetics. The impact of newer anesthetics on interpretability of ABR testing is unknown. This study compared sevoflurane versus propofol anesthesia on qualitative interpretability of ABR click-testing in children. METHODS: This prospective double-blind crossover study enrolled children (≤18 years old) receiving general anesthesia for elective ABR testing. All subjects received both sevoflurane and propofol anesthesias in the same ABR testing session. Deidentified ABR data were reviewed by 5 audiologists (blinded to anesthetic and patient) to determine threshold levels for hearing loss. The primary outcome was qualitative interpretability (false positive) of ABR click-testing. RESULTS: Each patient was tested at 4 different intensities in each ear: generating 624 records under each anesthetic, for a total of 1248 records. A few patients were tested at 5 different intensities in a single ear accounting for the additional 11 records, yielding 1259 records. Under sevoflurane anesthesia, 21 of the same patients (37 ears) were identified with abnormal ABR levels consistent with hearing loss (one or both ears). The probability of a patient being diagnosed with hearing "loss" in one or both ears was significantly less with propofol versus sevoflurane anesthesia (mid P =.0312). If patients with bilateral loss are compared, the mid P value is 0.0098. The effect size based on patients was medium to large, with a minimum value of Cohen w = 0.320. CONCLUSIONS: Sevoflurane produced more false positives for hearing loss and suggested more severe hearing loss than propofol. False-positive ABR tests, produced by certain anesthetic agents, can have significant life-long impact and negative psychosocial and developmental implications. Use of the intravenous anesthetic propofol is superior to sevoflurane for ABR testing in children.

BACKGROUND: Traditionally, fluid administration during kidney transplant surgery is guided by central venous pressure (CVP) despite its limited reliability as a parameter for assessing intravascular fluid volume, particularly in patients with cardiovascular diseases. The recommended goals at graft reperfusion are a mean arterial pressure of 90 mm Hg and a CVP of 12-14 mm Hg. This approach may increase the risk of significant adverse effects due to volume overload. Perioperative fluid therapy guided by dynamic indices of fluid responsiveness has been shown to optimize intravascular volume and prevent complications associated with overzealous administration of fluids in major abdominal surgeries. We hypothesized that pulse pressure variation (PPV)-guided fluid administration would result in better optimization of intravascular fluid volume compared with a CVP-guided strategy during kidney transplant surgery. METHODS: In this single-centre randomized double blinded trial, 77 end-stage renal disease patients, who underwent kidney transplant surgery under general anesthesia with epidural analgesia, were randomized to receive either CVP-guided (n = 35) or PPV-guided (n = 35) fluid therapy using predefined hemodynamic endpoints. The primary outcome was the total volume of intraoperative fluids administered. Secondary outcomes were intraoperative hemodynamic changes, serum lactate levels, serum creatinine, need for dialysis within the first week, creatinine elimination ratio, and incidence of immediate and delayed graft dysfunction. RESULTS: Results were analyzed for 70 patients. Eighty percent of the patients underwent living-related donor allograft kidney transplant. Operative variables related to donor characteristics, duration of surgery, graft cold ischemia time, and blood loss were comparable in both groups. The mean (standard deviation) volume of intravenous fluids administered intraoperatively was 1,346 (337) mL in the PPV-guided group vs 1,901 (379) mL in the CVP-guided group (difference in means, 556 mL; 95% confidence interval, 385 to 727; P = 0.001). There were no significant differences in secondary outcomes between the two groups. CONCLUSION: Pulse pressure variation -guided fluid administration significantly decreased the total volume of crystalloids compared with CVP-guided fluid therapy during the intraoperative period in patients who underwent kidney transplant surgery. Nevertheless, our study was underpowered to detect differences in secondary outcomes. TRIAL REGISTRATION: www.ctri.nic.in (CTRI/2018/01/011638); registered 31 January 2018.
RéSUMé: CONTEXTE: Traditionnellement, l'administration liquidienne pendant une chirurgie de transplantation rénale est guidée par la pression veineuse centrale (PVC) et ce, malgré sa fiabilité limitée en tant que paramètre d'évaluation du volume liquidien intravasculaire, en particulier chez les patients atteints de maladies cardiovasculaires. Les objectifs recommandés lors de la reperfusion du greffon sont une tension artérielle moyenne de 90 mmHg et une PVC de 1214 mmHg. Cette approche pourrait augmenter le risque d'effets indésirables importants dus à une surcharge volémique. Il a été démontré que la thérapie liquidienne périopératoire guidée par des indices dynamiques de réponse au remplissage optimisait le volume intravasculaire et prévenait les complications associées à l'administration liquidienne exagérée lors de chirurgie abdominale majeure. Nous avons émis l'hypothèse qu'une administration liquidienne guidée par la variation de pression différentielle (VPD et delta PP) entraînerait une meilleure optimisation du volume liquidien intravasculaire par rapport à une stratégie guidée par la PVC pendant une chirurgie de transplantation rénale. MéTHODE: Dans cette étude randomisée monocentrique à double insu, 77 patients atteints d'insuffisance rénale terminale, qui ont bénéficié d'une greffe rénale sous anesthésie générale avec analgésie péridurale, ont été randomisés à recevoir une administration liquidienne guidée soit par la PVC (n = 35) ou par la VPD (n = 35) en utilisant des critères hémodynamiques prédéfinis. Le critère d'évaluation principal était le volume total de liquides peropératoires administrés. Les critères secondaires comprenaient les variations hémodynamiques peropératoires, les taux sériques de lactate, la créatininémie, le besoin de dialyse au cours de la première semaine, le taux d'élimination de la créatinine et l'incidence de dysfonctionnement immédiat et retardé du greffon. RéSULTATS: Les résultats ont été analysés pour 70 patients. Quatre-vingts pour cent des patients ont subi une allogreffe de rein provenant d'un donneur vivant apparenté. Les variables opératoires liées aux caractéristiques du donneur, la durée de la chirurgie, le temps d'ischémie froide du greffon et les pertes sanguines étaient comparables dans les deux groupes. Le volume moyen (écart type) de liquides intraveineux administrés en peropératoire était de 1346 (337) mL dans le groupe guidé par VPD vs 1901 (379) mL dans le groupe guidé par PVC (différence de moyennes, 556 mL; intervalle de confiance à 95 %, 385 à 727; P = 0,001). Aucune différence intergroupe significative n'a été observée dans les critères d'évaluation secondaires. CONCLUSION: L'administration liquidienne guidée par la variation de pression différentielle a significativement diminué le volume total de cristalloïdes par rapport à la thérapie liquidienne guidée par la PVC pendant la période peropératoire chez les patients ayant bénéficié d'une greffe de rein. Néanmoins, notre étude ne disposait pas de la puissance suffisante pour détecter les différences dans les critères d'évaluation secondaires.

BACKGROUND: Postadenotonsillectomy unexpected admission remains an important challenge. Unexpected admissions can be quite frightening, increase health care burden, and cause unnecessary suffering in children and families. Identifying factors associated with postadenotonsillectomy unexpected admissions using a pragmatic approach could lead to a shift in the assessment and management of children presenting for adenotonsillectomy. METHODS: Institutional review board (IRB) approval, consent, and assent were obtained for this single-center, prospective, observational study done in children aged 0-17 years undergoing tonsillectomy. Data were collected from direct observation, electronic medical record, and phone calls using Research Electronic Data Capture (REDCap) database. Incidence, causes, and factors associated with 3-week and 3-day postadenotonsillectomy unexpected admissions were analyzed. RESULTS: The study included 2375 children. Clinical intraoperative adverse events were reported in 6.2%. Three-week and 3-day unexpected admissions occurred in 7.9% and 5.9%, respectively, with bleeding being the commonest reason for both. On multivariable analysis, for 3-week unexpected admissions, the odds ratio was 2.3 (95% confidence interval, 1.44-3.76) with using preoperative medications, 1.4 (1.02-1.97) with home medications for comorbidities, 0.56 (0.34-0.90) with using intraoperative acetaminophen, and 0.60 (0.36-0.94) with otolaryngologic preoperative comorbidity versus otherwise. For 3-day unexpected admissions, the odds ratio was 1.10 (1.05-1.16) with 1 U increase in total comorbidities, 1.70 (1.03-2.81) with the presence of recent upper respiratory infection, and 1.83 (1.16-2.90) with intravenous versus inhalational anesthesia induction. CONCLUSIONS: Overall, our study shows the factors that contribute to unexpected admissions postadenotonsillectomy. Identification of both modifiable and nonmodifiable factors associated with unexpected admissions after adenotonsillectomy will enable appropriate risk mitigation.

The Pediatric Perioperative Outcomes Group (PPOG) is an international collaborative of clinical investigators and clinicians within the subspecialty of pediatric anesthesiology and perioperative care which aims to use COMET (Core Outcomes Measures in Effectiveness Trials) methodology to develop core outcome setsfor infants, children and young people that are tailored to the priorities of the pediatric surgical population.Focusing on four age-dependent patient subpopulations determined a priori for core outcome set development: i) neonates and former preterm infants (up to 60 weeks postmenstrual age); ii) infants (>60 weeks postmenstrual age - <1 year); iii) toddlers and school age children (>1-<13 years); and iv) adolescents (>13-<18 years), we conducted a systematic review of outcomes reported in perioperative studies that include participants within age-dependent pediatric subpopulations. Our review of pediatric perioperative controlled trials published from 2008 to 2018 identified 724 articles reporting 3192 outcome measures. The proportion of published trials and the most frequently reported outcomes varied across pre-determined age groups. Outcomes related to patient comfort, particularly pain and analgesic requirement, were the most frequent domain for infants, children and adolescents. Clinical indicators, particularly cardiorespiratory or medication-related adverse events, were the most common outcomes for neonates and infants < 60 weeks and were the second most frequent domain at all other ages. Neonates and infants <60 weeks of age were significantly under-represented in perioperative trials. Patient-centered outcomes, heath care utilization, and bleeding/transfusion related outcomes were less often reported. In most studies, outcomes were measured in the immediate perioperative period, with the duration often restricted to the post-anesthesia care unit or the first 24 postoperative hours. The outcomes identified with this systematic review will be combined with patient centered outcomes identified through a subsequent stakeholder engagement study to arrive at a core outcome set for each age-specific group.

BACKGROUND: Exhaled nitric oxide (eNO) is a known biomarker for the diagnosis and monitoring of bronchial hyperreactivity in adults and children. AIMS: To investigate the potential role of eNO measurement for predicting perioperative respiratory adverse events in children, we sought to determine its feasibility and acceptability before adenotonsillectomy. METHODS: We attempted eNO testing in children, 4-12 years of age, immediately prior to admission for outpatient adenotonsillectomy. We used correlations between eNO levels and postoperative adverse respiratory events to make sample size predictions for future studies that address the predictability of the device. RESULTS: One hundred and three (53%) of 192 children were able to provide an eNO sample. The success rate increased with age from 23% (9%-38%) at age 4 to over 85% (54%-98%) after age 9. Using the eNO normal value (<20 ppb) as a cutoff, an expected sample size to detect a significant difference between children with and without adverse events is 868, assuming that respiratory adverse events occur in 29% of children. CONCLUSIONS: eNO testing on the day of surgery has limited feasibility in children younger than 7 years of age. The most common reason for failure was inadequate physical performance while interacting with the testing device. The role of this respiratory biomarker in the context of perioperative outcomes for pediatric adenotonsillectomy remains unknown and should be further studied with improved technologies.

Obstructive sleep apnea (OSA) has a prevalence of up to 5% in children and 50% in obese children. OSA is associated with various comorbidities in the general population and in the perioperative period. In this review, we will provide background of OSA and insights into the available treatment options both surgically and medically. Unlike adults, most pediatric OSA is treated with adenotonsillectomy. Continuous positive airway pressure therapy is the commonly used medical treatment. Management of pediatric OSA is multidisciplinary. We will discuss the surgical options and medical options of managing pediatric OSA.

OBJECTIVES: Obstructive sleep apnea (OSA) has a prevalence of 4% in children. Few studies have explored the role of secondhand smoke (SHS) on OSA severity and have shown contradicting results. Most studies have focused on the effect of SHS on snoring. This study explored the association of SHS exposure and OSA severity in children aged 3-18 years. METHODS: This is a retrospective single center IRB-approved study. Electronic Medical Records (EMR) were queried between 1/24/2015 and 1/24/2018 to obtain data on SHS exposure with standard questionnaires from perioperative database. SHS was analyzed as a binary variable and OSA was measured using obstructive apnea hypopnea index (OAHI) from polysomnography (PSG) as a continuous variable. Analyses were done on all children and in those with severe OSA (OAHI≥10/h) as a subgroup. RESULTS: EMR query yielded 101,884 children of whom 3776 had PSG. Limiting baseline PSG in 3-18-year-old and reliable information on SHS yielded 167 analyzable children of whom 70 had severe OSA. Children exposed to SHS had significantly more public insurance than non-exposed (p < 0.0001). Among children with severe OSA, median OAHI was significantly higher in SHS exposed compared to non-exposed (29.0vs.19.5,p = 0.04), but not across all children. In multivariable analysis SHS exposure increased OAHI by 48% in severe OSA subgroup (95%CI: 8%-102%; p = 0.01) when adjusted for race, body mass index, and adjusted household income. CONCLUSION: Children aged 3-18 years with severe OSA who were exposed to SHS were found to have 1.48 increase in odds of OAHI than those without SHS exposure. Results could be limited by retrospective nature of study and EMR tools.

BACKGROUND: The Snoring, Trouble Breathing, and Un-Refreshed (STBUR) questionnaire is a five-question screening tool for pediatric sleep-disordered breathing and risk for perioperative respiratory adverse events in children. The utility of this questionnaire as a preoperative risk-stratification tool has not been investigated. In view of limited availability of screening tools for preoperative pediatric sleep-disordered breathing, we evaluated the questionnaire's performance for postanesthesia adverse events that can impact postanesthesia care and disposition. METHODS: The retrospective study protocol was approved by the institutional research board. The data were analyzed using two different definitions for a positive screening based on a five-point scale: low threshold (scores 1 to 5) and high threshold (score of 5). The primary outcome was based on the following criteria: (a) supplemental oxygen therapy following postanesthesia care unit (PACU) stay until hospital discharge, (b) greater than two hours during phase 1 recovery, (c) anesthesia emergency activation in the PACU, and (d) unplanned hospital admission. RESULTS: About 6025 patients completed the questionnaire during the preoperative evaluation. And 1522 patients had a low threshold score and 270 had a high-threshold score. We found statistically significant associations in three outcomes based on the low threshold score: supplemental oxygen therapy (negative-predictive value [NPV] 0.97, 95% CI 0.97-98), PACU recovery time (NPV 0.99, 95% CI 0.99-0.99) and escalation of care (NPV 0.98, 95% CI 0.97-0.98). Positive-predictive values were statistically significant for all outcomes except anesthesia emergency in the PACU. CONCLUSION: The Snoring, Trouble Breathing, and Un-Refreshed questionnaire identified patients at higher risk for prolonged phase 1 recovery, oxygen therapy requirement, and escalation of care. The questionnaire's high-negative predictive value and specificity may make it useful as a screening tool to identify patients at low risk for prolonged stay in PACU.

BACKGROUND: Unnecessarily long preprocedural fasting can cause suffering and distress for children and their families. Institutional fasting policies are designed to consistently achieve minimum fasting times, often without regard to the extent to which actual fasting times exceed these minimums. Children at our hospital frequently experienced clear liquid fasting times far in excess of required minimums. AIMS: The aim of this study was to utilize quality improvement methodology to reduce excess fasting times, with a goal of achieving experienced clear liquid fasting times ≤4 hours for 60% of our patients. METHODS: This quality improvement project was conducted between July 2017 and August 2018. A multidisciplinary team performed a series of Plan-Do-Study-Act cycles focused on children undergoing elective procedures at a large children's hospital. Key drivers for clear liquid fasting times and relevant balancing measures were identified. Data were analyzed using control charts and statistical process control methods. RESULTS: Approximately 16 000 children were involved in this project. Over the course of the project, the percentage of children with goal clear liquid fasting times improved from the baseline of 20%-63%, with a change in the mean fasting time from 9 hours to 6 hours. There were no significant effects on balancing measures (case delays/cancellations and clinically significant aspiration events). CONCLUSION: Using quality improvement methodology, we safely improved the duration of preoperative fasting experienced by our patients. Our results provide additional data supporting the safety of more permissive 1-hour clear liquid fasting minimums. We suggest other institutions pursue similar efforts to improve patient and family experience.

BACKGROUND: Anesthestic management of congenital pulmonary airway malformation has not been well described in the literature. It is not clear whether one-lung ventialtion is indicated during thoracoscopic lobectomy and if so, what is the best technique achieve it. AIMS: We describe the variables with the two commonly performed surgical techniques, thoracoscopic lobectomy and open thoracotomy, from our institutional database to assess the role of lung isolation and the preferable method of lung isolation technique for congenital pulmonary airway malformation resections. METHODS: After institutional review board approval, fetal center records were reviewed retrospectively from January 2010 to July 2016 for patients who underwent congenital pulmonary airway malformation resection. The primary goal was to describe the anesthesia induction-airway management techniques with emphasis on one-lung ventilation techniques. RESULTS: Among the 65 resections, one-lung ventilation was performed in 30 resections (46%) and was primarily achieved by endobronchial intubation in most cases (80%). One-lung ventilation was performed in a greater number of resections with thoracoscopic lobectomy (96%) compared to open thoracotomies. CONCLUSION: From our institution cohort, one-lung ventilation was more commonly used during thoracoscopic resections and was most commonly achieved with endobronchial intubation. Most patients were induced with inhalational anesthesia (sevoflurane), nondepolarizing neuromuscular blocker, and gentle positive pressure ventilation for intubation.
