RESUMEN
BACKGROUND: The Pediatric Anesthesia COVID-19 Collaborative (PEACOC) is a research network to advance the care of children during the pandemic. Here we calculate the prevalence of coronavirus disease 2019 (COVID-19) among children undergoing anesthesia, look at prevalence in the population data from the Centers for Disease Control and Prevention (CDC), and assess independent risk factors for infection. METHODS: This was a multicenter, retrospective, observational study. Children aged 28 days to 18 years scheduled for anesthesia services at 12 centers requiring universal COVID-19 testing from March 29, 2020 to June 30, 2020 were included. COVID-19 positivity rates among those tested were plotted and trends were assessed using the Cochran Armitage test of trend. Independent risk factors were explored using multivariable logistic regression. RESULTS: Data were collected and analyzed on 33,320 anesthesia encounters including 265 children with COVID-19. Over the study period, the rates of infections in the pediatric anesthesia population did not demonstrate a significant trend. In the general population, there was a significant downward trend in infection rates ( P < .001). In exploratory analysis, multivariable risk factors for a COVID-19 positive test were Black/African American race, Hispanic ethnicity, American Society of Anesthesiologists (ASA) physical status III or above, overweight and obese body mass index (BMI), orthopedic cases, abdominal cases, emergency cases, absence of injury and trauma, and West region (all P < .05). CONCLUSIONS: Rates of COVID-19 in pediatric anesthesia patients were consistently lower than in the general population. Independent risk factors of a positive test for children were identified. This is the first time universal testing for a single infectious disease was undertaken on a wide scale. As such, the association of infection with surgical case type or emergency case status is unprecedented.

INTRODUCTION: Fluid administration is an important aspect of the management of children undergoing liver transplantation and may impact postoperative outcomes. Our aim was to evaluate the association between volume of intraoperative fluid administration and our primary outcome, the duration of postoperative mechanical ventilation following pediatric liver transplantation. Secondary outcomes included intensive care unit length of stay and hospital length of stay. METHODS: We conducted a multicenter, retrospective cohort study using electronic data from three major pediatric liver transplant centers. Intraoperative fluid administration was indexed to weight and duration of anesthesia. Univariate and stepwise linear regression analyses were conducted. RESULTS: Among 286 successful pediatric liver transplants, the median duration of postoperative mechanical ventilation was 10.8 h (IQR 0.0, 35.4), the median intensive care unit length of stay was 4.3 days (IQR 2.7, 6.8), and the median hospital length of stay was 13.6 days (9.8, 21.1). Univariate linear regression showed a weak correlation between intraoperative fluids and duration of ventilation (r2 = .037, p = .001). Following stepwise linear regression, intraoperative fluid administration remained weakly correlated (r2 = .161, p = .04) with duration of postoperative ventilation. The following variables were also independently correlated with duration of ventilation: center (Riley Children's Health versus Children's Health Dallas, p = .001), and open abdominal incision after transplant (p = .001). DISCUSSION: The amount of intraoperative fluid administration is correlated with duration of postoperative mechanical ventilation in children undergoing liver transplantation, however, it does not seem to be a strong factor. CONCLUSIONS: Other modifiable factors should be sought which may lead to improved postoperative outcomes in this highly vulnerable patient population.

BACKGROUND: Age- and sex-specific reference nomograms for intraoperative blood pressure have been published, but they do not identify harm thresholds. The authors therefore assessed the relationship between various absolute and relative characterizations of hypotension and acute kidney injury in children having noncardiac surgery. METHODS: The authors conducted a retrospective cohort study using electronic data from two tertiary care centers. They included inpatients 18 yr or younger who had noncardiac surgery with general anesthesia. Postoperative renal injury was defined using the Kidney Disease Improving Global Outcomes definitions, based on serum creatinine concentrations. The authors evaluated potential renal harm thresholds for absolute lowest intraoperative mean arterial pressure (MAP) or largest MAP reduction from baseline maintained for a cumulative period of 5 min. Separate analyses were performed in children aged 2 yr or younger, 2 to 6 yr, 6 to 12 yr, and 12 to 18 yr. RESULTS: Among 64,412 children who had noncardiac surgery, 4,506 had creatinine assessed preoperatively and postoperatively. The incidence of acute kidney injury in this population was 11% (499 of 4,506): 17% in children under 6 yr old, 11% in children 6 to 12 yr old, and 6% in adolescents, which is similar to the incidence reported in adults. There was no association between lowest cumulative MAP sustained for 5 min and postoperative kidney injury. Similarly, there was no association between largest cumulative percentage MAP reduction and postoperative kidney injury. The adjusted estimated odds for kidney injury was 0.99 (95% CI, 0.94 to 1.05) for each 5-mmHg decrease in lowest MAP and 1.00 (95% CI, 0.97 to 1.03) for each 5% decrease in largest MAP reduction from baseline. CONCLUSIONS: In distinct contrast to adults, the authors did not find any association between intraoperative hypotension and postoperative renal injury. Avoiding short periods of hypotension should not be the clinician's primary concern when trying to prevent intraoperative renal injury in pediatric patients.

WHAT IS KNOWN AND OBJECTIVE: Opioids are commonly administered to infants having surgery. Opioid induced hyperalgesia (OIH) is a known adverse effect of opioids in adults but can be difficult to identify in infants. CASE SUMMARY: A 3-month-old received high-dose fentanyl during anorectoplasty for imperforate anus. He had signs and symptoms of OIH immediately after surgery. His pain and agitation were difficult to manage but improved after he received ketamine. WHAT IS NEW AND CONCLUSION: OIH should be considered in infants postoperatively when pain worsens despite administration of escalating doses of opioids. Ketamine can be an effective therapeutic for OIH.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with high perioperative morbidity and mortality among adults. The incidence and severity of anesthetic complications in children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown. We hypothesized that there would be an increased incidence of intra- and postoperative complications in children with SARS-CoV-2 infection as compared to those with negative testing. METHODS: We conducted a retrospective cohort study analyzing complications for children <18 years of age who underwent anesthesia between April 28 and September 30, 2020 at a large, academic pediatric hospital. Each child with a positive SARS-CoV-2 test within the prior 10 days was matched to a patient with a negative SARS-CoV-2 test based on American Society of Anesthesiologists (ASA) physical status, age, gender, and procedure. Children who were intubated before the procedure, underwent organ transplant surgery, or had severe COVID-19 were excluded. The primary outcome was the risk difference of a composite of intra- or postoperative respiratory complications in children positive for SARS-CoV-2 compared to those with negative testing. Secondarily, we used logistic regression to determine the odds ratio for respiratory complications before and after adjustment using propensity scores weighting to adjust for possible confounders. Other secondary outcomes included neurologic, cardiovascular, hematologic, and renal complications, unanticipated postoperative admission to the intensive care unit, length of hospital stay, and mortality. RESULTS: During the study period, 9812 general anesthetics that had a preoperative SARS-CoV-2 test were identified. Sixty encounters occurred in patients who had positive SARS-CoV-2 testing preoperatively and 51 were included for analysis. The matched controls cohort included 99 encounters. A positive SARS-CoV-2 test was associated with a higher incidence of respiratory complications (11.8% vs 1.0%; risk difference 10.8%, 95% confidence interval [CI], 1.6-19.8; P = .003). After adjustment, the odds ratio for respiratory complications was 14.37 (95% CI, 1.59-130.39; P = .02) for SARS-CoV-2-positive children as compared to controls. There was no occurrence of acute respiratory distress syndrome, postoperative pneumonia, or perioperative mortality in either group. CONCLUSIONS: Pediatric patients with nonsevere SARS-CoV-2 infection had higher rates of perianesthetic respiratory complications than matched controls with negative testing. However, severe morbidity was rare and there were no mortalities. The incidence of complications was similar to previously published rates of perianesthetic complications in the setting of an upper respiratory tract infection. This risk persisted after adjustment for preoperative upper respiratory symptoms, suggesting an increased risk in symptomatic or asymptomatic SARS-CoV-2 infection.

BACKGROUND: Anesthetic regimens using dexmedetomidine and short-acting opioids have been suggested as potential alternatives to sevoflurane-based anesthesia in children. The primary aim of this study is to compare demographics, intraoperative characteristics, and complications of general anesthetics in which dexmedetomidine and opioids were used without sevoflurane, or in combination with a low sevoflurane concentration, in children 36 months old and younger. The secondary aim is to evaluate intraoperative bispectral index (BIS) values when available in these patients. METHODS: General anesthetics performed between January 1, 2017, and May 1, 2018, in children 2 years and younger who received dexmedetomidine and remifentanil, with or without sevoflurane, were identified. Additional anesthetics performed during this time in children 36 months and younger who received dexmedetomidine and opioids and had BIS monitoring were also identified. Charts were reviewed for demographic and intraoperative variables, including drug administration and hemodynamic data. RESULTS: A total of 244 patients were identified. All but 22 patients received remifentanil. Ninety-two patients received sevoflurane with a mean end-tidal concentration of 0.84% (SD 0.43). Compared to the sevoflurane group, the nonsevoflurane group received more remifentanil (median dose 0.4 µg/kg/min vs 0.2 µg/kg/min, difference of 0.1 µg/kg/min, 95% CI 0.1-0.3, P < .001) and more dexmedetomidine (median dose 0.9 µg/kg/h vs 0.3 µg/kg/h, difference of 0.6 µg/kg/h, 95% CI 0.4-0.8, P < .001), and had a higher mean arterial pressure (median 53 mm Hg vs 42 mm Hg, difference of 11 mm Hg, 95% CI 8.1-14.8, P < .001). Complications between the two groups were comparable. The median percent intraoperative time with BIS reading <60 was 71.6% (95% CI: 63.3%-79.8%). CONCLUSION: Dexmedetomidine and opioids can effectively be used in young children as an alternative total intravenous anesthesia technique with or without <1 minimum alveolar concentration of sevoflurane. Bispectral index monitoring reveals a likely sufficient depth of hypnosis.

BACKGROUND: Little is known regarding the incidence and contributing factors of postdischarge nausea and vomiting in children. AIMS: The aim of this study was to determine the incidence of postdischarge nausea and vomiting in day surgery patients and to identify demographic, intraoperative, and postoperative variables that influence the risk. METHODS: In this prospective observational study, a postdischarge questionnaire was administered to parents of ambulatory patients who received anesthesia and the electronic records were reviewed. RESULTS: Of 1041 ambulatory patients who received general anesthesia, 143 (14%) experienced postdischarge nausea and vomiting. Patients who did not receive intraoperative opioids had a lower incidence (8%) than those who received short-acting opioids (14%) (difference of 6%, 95% CI 1.9%-10.2%, P < .001) or long-acting opioids (24%) (difference of 16%, 95% CI 8.1%-24.3%, P < .001). Patients who received short-acting opioids also had a lower incidence than those who received long-acting opioids (difference of 10%, 95% CI 2.2%-18.1%, P < .001). The incidence also differed between those patients who received postdischarge opioids at home (29%) and those who did not (13%) (difference of 16%, 95% CI 7.5%-27.6%, P < .001). There was no association with age, gender, airway management, nitrous oxide use, amount of intravenous fluids, duration of anesthesia, intraoperative antiemetic administration or dosage, length of time from recovery room discharge to first oral intake, or length of ride home from the hospital. Multivariate generalized linear regression analysis confirmed intraoperative (short-acting opioids odds ratio 1.686, 95% CI 1.020-2.787; long-acting opioids odds ratio 3.093, 95% CI 1.634-5.874) and postdischarge (odds ratio 2.037 95% CI 1.142-3.632) opioids to be independent risk factors for postdischarge nausea and vomiting. CONCLUSION: We found an incidence of postdischarge nausea and vomiting of 14%. Intraoperative and postdischarge opioids increase the risk, with long-acting intraoperative opioids further accentuating the risk.

BACKGROUND: Adenotonsillectomy is often curative for pediatric obstructive sleep apnea, yet children remain at high risk of respiratory complications in the postoperative period. We sought to determine the incidence and risk factors for respiratory depression and airway obstruction, as well as clinically apparent respiratory events in the post-anesthesia care unit (PACU) in high-risk children after adenotonsillectomy. METHODS: In this prospective cohort study, we enrolled 60 high-risk children having adenotonsillectomy. Our primary outcome was respiratory depression and airway obstruction in the PACU measured using a noninvasive respiratory volume monitor (RVM) and defined by episodes of predicted minute ventilation less than 40% for at least 2 min. We measured clinically apparent respiratory events using continuous observation by trained study staff. RESULTS: The median (range) age of our sample was 4 years (1, 16) and 27 (45%) were female. Black and Hispanic race children comprised 80% (n = 48) of our cohort. Thirty-nine (65%) had at least one episode of PACU respiratory depression or airway obstruction measured using the RVM, while only 21 (35%) had clinically apparent respiratory events. Poisson regression demonstrated the following associations with an increase in episodes of respiratory depression and airway obstruction: BMI Z-score less than -1 (estimate 3.91; [95%CI 1.49-10.23]), BMI Z-score 1-2 (estimate 2.04; [1.20-3.48]), and two or more comorbidities (estimate 1.96; [1.11-3.46]). CONCLUSIONS: Respiratory volume monitoring in the immediate postoperative period after pediatric high-risk adenotonsillectomy identifies impaired ventilation more frequently than is clinically apparent.

STUDY OBJECTIVE: To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection. DESIGN: A prospective cohort study. SETTING: A tertiary, freestanding pediatric hospital in Dallas, Texas. PATIENTS: Children <18 years of age with positive respiratory viral testing who underwent general anesthesia. INTERVENTION: Measurement of incidence of PRAE and severe adverse events during the first 7 postoperative days. MEASUREMENTS: The primary outcome was a composite of PRAE: oxygen saturation < 90% for >5 min, supplemental oxygen for >2 h after anesthesia, laryngospasm, and bronchospasm. The secondary outcome was severe adverse events: high flow nasal cannula >6 l of oxygen per minute, admission to the ICU for escalation of respiratory support post-anesthetic, acute respiratory distress syndrome, postoperative pneumonia, cardiovascular arrest, extracorporeal life support, and death. MAIN RESULTS: In this convenience sample of 196 children, 83 were symptomatic and 113 were asymptomatic. The risk of PRAE was similar in children with active viral symptoms and asymptomatic children (risk difference: -1.9%; 95% CI: -10.9, 7.9%), but higher among children with documented fever within 48 h of the anesthetic (risk difference: 20.8%; 95% CI: 5.3, 39.7%). The multivariable adjusted odds ratio of PRAE was 0.68 (95% CI: 0.25, 1.85) for symptomatic compared to asymptomatic patients, and 0.46 (95% CI: 0.14, 1.44) for patients with SARS-CoV-2 compared to non-SARS-CoV-2 infection. CONCLUSIONS: There was no significant difference in the incidence of PRAE between symptomatic and asymptomatic children with laboratory confirmed viral respiratory infection, and between children with the Omicron variant of SARS-CoV-2 compared to non-SARS-CoV-2 respiratory viruses. However, the risk was increased in children with recent fever.

Sugammadex is a novel reversal agent for the neuromuscular blocking agents rocuronium and vecuronium; it has been shown to rapidly and completely reverse neuromuscular blockade for rocuronium and vecuronium, even when the blockade is profound. We present the case of a 2-week-old, 850-g infant born at 25 weeks' gestation, who presented to the operating room for exploratory laparotomy and repair of ileal atresia. Anesthesia was induced and neuromuscular blockade with 1.2 mg/kg of rocuronium was administered. The neonate experienced rapid oxyhemoglobin desaturation and progressively became very difficult to mask ventilate. Direct laryngoscopy failed to result in successful intubation of the trachea and ventilation became impossible. To reverse the effects of rocuronium, 16 mg/kg of sugammadex was administered. Immediately after, the infant resumed spontaneous ventilation and was able to maintain adequate oxyhemoglobin saturation between 90% and 95% with supplemental oxygen. To our knowledge, this is the first report of successful reversal of neuromuscular blockade, with sugammadex, in an emergent situation after failure to intubate/ventilate an extremely low birth weight infant.
RESUMEN
: A 4-month-old girl initially presented to the pediatric ICU at 9 days old with multiorgan failure and cerebellar hemorrhage secondary to disseminated enteroviral infection and was eventually listed for liver transplant. Due to severe coagulopathy, she developed a hemothorax after line placement. Despite operative exploration and multiple recombinant factor VIIa doses, massive bleeding continued. The bleeding was finally controlled with thromboelastography-targeted platelet and cryoprecipitate transfusion in addition to four-factor prothrombin complex concentrate administration. This management strategy was invaluable in controlling bleeding from an iatrogenic cause.

BACKGROUND: Effective pediatric intensive care requires addressing many important aspects of care delivery during morning rounds, often achieved using a rounding checklist. Our objective was to develop a care goal rounding template and then double the reliability of discussion of rounding topics during morning rounds without the use of a checklist. METHODS: The Institute for Healthcare Improvement Model for Improvement was used for this initiative. A care goal rounding template was established through discussions and consensus with pediatric intensive care unit (PICU) faculty. Rounds were audited in a blinded fashion over a 3-month period to obtain baseline data on rounding topic discussion. Three interventions were then trialed (plan, do, study, act cycles) over a 12-month period. Weekly reliability in rounding topic discussion was tracked. RESULTS: Baseline reliability with discussion of rounding topics was 36%. The first intervention included the use of a standardized progress note in the electronic health record, which contained topics and served to prompt the discussion on rounds. The second intervention was implementation of laminated cards provided to PICU fellows highlighting the elements of the care goal rounding template. The third intervention addressed a standardized handoff sheet often used during rounds. Mean reliability for discussion of rounding topics improved to 52% shortly following the second intervention. Reliability was sustained more than 1 year later. CONCLUSIONS: Following the establishment of a PICU care goal rounding template and various interventions, the reliability in discussing important care goal elements on patient rounds improved.
