RESUMO
OBJECTIVE: To study the organization of inter-hospital transport of pediatric and neonatal patients in Spain, Portugal and Latin America. DESIGN: An observational study was performed. An on-line survey was sent by email including questions about characteristics of national, regional and local health transport systems, vehicles, material, and composition of the transport team and their training. SETTING: Hospital pediatric healthcare professionals treating children in Spain, Portugal and Latin America RESULTS: A total of 117 surveys from 15 countries were analyzed. Of them, 55 (47%) come from 15 regions of Spain and the rest from Portugal and 13 Latin American countries. The inter-hospital transport of pediatric patients is unified only in the Spanish regions of Baleares and Cataluña and in Portugal. Chile has a mixed unified transport system for pediatric and adult patients. Only 51.4% of responders have an educational program for the transport personnel, and only in 36.4% of them the educational program is specific for pediatric patients. In Spain and Portugal the transport is executed mostly by public entities, while in Latin America public and private systems coexist. Specific pediatric equipment is more frequent in the transport teams in the Iberian Peninsula than in Latin American teams. The specific pediatric transport training is less frequent for teams in Latin America than on Spain and Portugal. CONCLUSIONS: There is a great variation in the organization of children transport in each country and region. Most of countries and cities do not have unified and specific teams of pediatric transport, with pediatric qualified personnel and specific material.

AIM: To describe the morbimortality associated to the development of acute kidney injury (AKI) defined by the pediatric adaptation of the RIFLE criteria in a Pediatric Intensive Care Unit (PICU). DESIGN: A retrospective cohort study was carried out. SETTING: Children admitted to a PICU in a tertiary care hospital. Patients or participants A total of 320 children admitted to a tertiary care hospital PICU during the year 2011. Neonates and renal transplant patients were excluded. Primary endpoints AKI was defined and classified according to the pediatric adaptation to the RIFLE criteria. PICU and hospital stays, use of mechanical ventilation and mortality were used to evaluate morbimortality. RESULTS: A total of 315 children met the inclusion criteria, with a median age of 19 months (range 6-72). Of these patients, 128 presented AKI (73 reached the Risk category and 55 reached the Injury and Failure categories). Children with AKI presented a longer PICU stay (6.0 [4.0-12.5] vs. 3.5 [2.0-7.0] days) and hospital stay (17 [10-32] vs. 10 [7-15] days), and a greater need for mechanical ventilation (61.7 vs. 36.9%). The development of AKI was an independent factor of morbidity, associated with a longer PICU and hospital stay, and with a need for longer mechanical ventilation, with a proportional relationship between increasing morbidity and the severity of AKI. CONCLUSION: The development of AKI in critically ill children is associated with increased morbimortality, which is proportional to the severity of renal injury.

OBJECTIVE: To analyze mortality and resource consumption in patients with long stays in pediatric intensive care units (PICUs). DESIGN: A retrospective, descriptive case series study. SCOPE: Medical-surgical PICU in a third level hospital. PATIENTS: Data were collected from patients with a stay of 28 days or more in PICU between 2006 and 2010. Of the 2118 patients assisted in this period, 83 (3.9%) required prolonged stay. STUDY VARIABLES: Morbidity-mortality and resource consumption among patients with prolonged stay in the PICU. RESULTS: Mortality was higher in patients with a long stay (22.9%) than in the rest of patients (2%) (p<0.001). In 52.6% of these patients, death occurred after withdrawal of treatment or after not starting resuscitation measures. Patients with prolonged stay showed a high incidence of nosocomial infection (96.3%) and an important consumption of healthcare resources (97.6% required conventional mechanical ventilation, 90.2% required transfusion of blood products, 86.7% required intravenous vasoactive drugs and 22.9% required extracorporeal membrane oxygenation [ECMO]). CONCLUSIONS: Critical children with prolonged stay in the PICU show important morbidity and mortality, and an important consumption of healthcare resources. The adoption of specific measures permitting early identification of patients at risk of prolonged stay is needed in order to adapt therapeutic measures and available resources, and to improve treatment efficiency.

The SARS-CoV-2 pandemic has created new scenarios that require modifications to the usual cardiopulmonary resuscitation protocols. The current clinical guidelines on the management of cardiorespiratory arrest do not include recommendations for situations that apply to this context. Therefore, the National Cardiopulmonary Resuscitation Plan of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC), in collaboration with the Spanish Group of Pediatric and Neonatal CPR and with the Teaching Life Support in Primary Care program of the Spanish Society of Family and Community Medicine (SEMFyC), have written these recommendations, which are divided into 5 parts that address the main aspects for each healthcare setting. This article consists of an executive summary of them.

OBJECTIVE: To analyse the prognostic factors for complications in children with bronchiolitis admitted to a pediatric intensive care unit (PICU). PATIENTS AND METHOD: A retrospective study was performed on children with bronchiolitis admitted into a PICU between 2000 and 2006. Univariate and multivariate analysis were performed to study the prognostic factors of complications, mechanical ventilation requirements, mortality and PICU stays of more than 15 days. RESULTS: A total of 110 patients were studied, of whom 72 (65.5%) had high risk factors: prematurity (39.1%), cardiac disease (38.2%) and bronchopulmonary dysplasia (16.3%). A total of 82.7% of patients had complications; 26% need invasive mechanical ventilation and the mortality was 3.6%, and 16.4% stayed in PICU for more than 15 days. Factors associated with mechanical ventilation were the clinical Wood-Downes score and heart disease. A weight less than 5 kg was associated with complications; heart disease and invasive mechanical ventilation were associated with a longer PICU stay; prematurity and mechanical ventilation were associated with mortality. CONCLUSIONS: Children with bronchiolitis admitted into the PICU had a high frequency of complications, often needed mechanical ventilation and had long stays in the PICU, but the mortality is low. The best prognostic factors on admission into the PICU were the acute respiratory insufficiency score, the presence of heart disease and were premature at birth.

OBJECTIVE: To analyze the efficacy of a high-flow oxygen therapy system in children with moderate respiratory failure and/or high oxygen requirements. PATIENTS AND METHODS: We performed a prospective, observational clinical study of patients treated with a high-flow oxygen therapy system via nasal cannulae. The following variables were analyzed: clinical severity score, respiratory rate, heart rate, clinical improvement, oxygen saturation, blood gases, complications, and the need for ventilation after starting the treatment. RESULTS: Eighteen treatments were studied in 16 patients (two girls and 14 boys) aged between 2 and 156 months. With the high-flow oxygen therapy system, respiratory rate slightly decreased from 34.5 bpm to 32.2 bpm (p<0.04) and O2 saturation increased from 90.2% to 93.5% (p<0.02). Fourteen patients showed a clinical improvement and/or tolerated the change from the previous respiratory assistance. The duration of treatment was 3 days (range: 6 hours to 25 days). Mild complications (initial irritability and excessive humidity) were observed in two patients, but treatment interruption was not required. No secondary respiratory tract infections were observed. The system was withdrawn in four patients, due to lack of improvement in two patients, deterioration after initial improvement in one patient, and failure of the system's temperature regulation in one patient. CONCLUSIONS: The high-flow oxygen therapy system is effective in a large percentage of children with high oxygen requirements and/or moderate respiratory failure.

OBJECTIVE: To analyze the changes in respiratory parameters in a Servoi ventilator with heliox. MATERIAL AND METHODS: In vitro study with a Servoi (Maquet) ventilator in volume controlled (VC), pressure controlled (PC) and volume control regulated by pressure (VCPR) modes connected to an artificial lung. A heliox tank with a fixed concentration of helium 70 % and oxygen 30 % was connected to the air inlet of the ventilator. The ventilator was set in VC mode with tidal volumes of 30, 50, 100, 250 and 500 ml; in PC mode with pressure of 20 and 30 cmH(2)O and in VCPR mode with tidal volume of 150 ml. In each case FiO(2) of 21, 30, 40, 50, 60, 70, 80, 90 and 100 % was used. The FiO(2), inspired and expired tidal volume and inspiratory pressure measured by the ventilator and a pitot spirometer (Datex_S5) were compared. RESULTS: In VC and VCPR modes the increase in helium produced a progressive decrease in the pressure needed to administrate the set volume. Heliox also produced a decrease in the tidal volume measured by the spirometer and the tidal expired volume measured by the respirator. In PC mode, heliox produced a progressive increase in the inspired tidal volume, increasing the differences between inspired and expired tidal volumes. CONCLUSIONS: Heliox used with Servoi ventilator produces a decrease in inspiratory pressures in VC and VCPR modes, and an increase in inspiratory tidal volume in PC mode. In all modes heliox reduced the expired tidal volume measured by the ventilator and the spirometer. These changes should be borne in mind if heliox is used with this ventilator.

Cardiopulmonary resuscitation (CPR) is a medical activity that involves major ethical issues. As in other areas of clinical ethics, CPR decisions must be based on the principles of autonomy, beneficence, nonmaleficence, and justice. The decision-making process is more difficult in emergency situations, and when the patient is a minor, the parents and the child's best interests must be taken into consideration. There are specific situations in which starting CPR is clearly indicated and others in which ceasing resuscitation maneuvers is justified. Do not attempt resuscitation orders must be respected by health staff. Other ethical issues involved in CPR include resuscitation of potential organ donors, learning CPR procedures, research in CPR, and the information given to the parents of children with cardiorespiratory arrest.

Cardiorespiratory arrest and the need for cardiopulmonary resuscitation can occur anywhere, both in the out-of-hospital and in-hospital settings. Therefore, all healthcare centers (hospitals, primary care facilities, out-of-hospital emergency services) must be prepared to initiate life support procedures in children and to treat other life-threatening emergencies. To achieve this objective, adequate material including a full crash cart or resuscitation trolley is essential and must be available in all healthcare centers. Specific items contained in the trolley can vary according to the characteristics of the facility and the most probable type of resuscitation needed (for example, neonatal resuscitation). At least one resuscitation trolley must be available in primary care centers, pediatric intensive care units, emergency departments, out-of-hospital emergency services, and pediatric wards. The trolley must be located in an easily accessible site and must contain only indispensable material. It is essential to include instruments in several sizes, covering children of all ages, as well as enough spare instruments and medications that could be required during resuscitation. The material must be checked periodically and all the staff (physicians, nurses, and auxiliary personnel) must be familiar with the trolley's contents and the location of all material and drugs.

OBJECTIVE: To study energy expenditure (EE) in critically ill infants and children and its correlation with clinical characteristics, treatment, nutrition, caloric intake, and predicted energy expenditure calculated through theoretical formulas. PATIENTS AND METHODS: A prospective observational study was conducted in critically ill infants and children. Indirect calorimetry measurements were performed using the calorimetry module of the S5 Datex monitor. Data on mechanical ventilation, nutrition, and caloric intake were registered. Theoretical equations of energy requirement (WHO/FAO, Harris-Benedict, Caldwell-Kennedy, Maffeis, Fleisch, Kleiber and Hunter) were calculated. The statistical analysis was performed using the SPSS 12.0 package. RESULTS: Sixty-eight EE determinations were performed in 43 critically ill infants and children aged between 10 days and 15 years old. Measured EE was 58.4 (18.4) kcal/kg/day, with wide individual variability. EE was significantly lower in infants and children who had undergone cardiac surgery than in the remainder. No correlation was found between EE and mechanical ventilation parameters, vasoactive drugs, sedatives, or muscle relaxants. A correlation was found between caloric intake and EE. In a high percentage of patients, predictive equations did not accurately estimate EE. The respiratory quotient was not useful to diagnose overfeeding or underfeeding. CONCLUSIONS: Wide individual variability in EE was found in critically ill infants and children. Predictive equations did not accurately estimate EE. Indirect calorimetry measured by a specific module is a simple method that could allow generalized use of EE measurement in critically ill pediatric patients undergoing mechanical ventilation.

OBJECTIVE: To analyze response to heliox therapy in critically ill infants and children with upper and/or lower airway respiratory insufficiency. PATIENTS AND METHODS: Sixty-five patients, aged between 12 days and 8 years old, treated with heliox through facial mask, nasal prongs or non-invasive ventilation were studied. Diagnoses were bronchiolitis (25), upper postextubation respiratory insufficiency (19), respiratory insufficiency after airway surgery (14), and croup-laryngotracheomalacia (7). Response to heliox treatment was measured by the change in clinical scores, respiratory rate, heart rate, pulse oximetry, blood gas analysis, and the need for non-invasive and invasive mechanical ventilation. RESULTS: Fifty-four patients (83.1 %) improved after heliox therapy, with statistically significant differences in clinical score (from 8.7 to 5.5), respiratory rate (from 51.4 to 38.8 rpm), and heart rate (from 161.6 to 145.6 bpm). No changes were observed in saturation or blood gas analysis. After heliox therapy, 29.8 % of patients required non-invasive ventilation and 26.5 % required intubation. Patients with bronchiolitis and those aged less than 1 year had a lesser response to heliox therapy and more frequently required non-invasive ventilation. No significant differences were found in intubation requirements. No adverse effects were observed. CONCLUSIONS: Heliox therapy improved clinical scores in infants and children with upper and lower airway respiratory insufficiency, but a significant percentage of patients needed non-invasive or invasive mechanical ventilation.

OBJECTIVE: To assess the validity of the Pediatric Risk of Mortality score (PRISM), the Pediatric Index of Mortality (PIM) and the PIM 2 in two Spanish pediatric intensive care units. PATIENTS AND METHODS: We prospectively studied 241 critically ill children consecutively admitted over a 6-month period. The overall performance of the scoring systems was assessed by the Standardized Mortality Ratio (SMR), comparing observed deaths with expected deaths by each index. Discrimination (the ability of the model to distinguish between patients who live and those who die) was quantified by calculating the area under the receiver operating characteristic (ROC) curve. Calibration (the accuracy of mortality risk predictions) was calculated with the Hosmer-Lemeshow goodness-of-fit test, in which statistical calibration is evidenced by p > 0.05. RESULTS: The mortality rate was 4.1 %. PRISM overestimated mortality (SMR = 0.44). Discrimination was better for PRISM and PIM 2 than for PIM (areas under ROC curves: 0.883, 0.871, and 0.800 respectively), with no significant differences. Finally, calibration was acceptable for PIM 2 (x2 (8) = 4.8730, p 0.8461) and for PIM (x2 (8) = 8.0876, p 0.5174), but no statistical calibration was found for PRISM (x2 (8) = 15.0281, p 0.0133). CONCLUSIONS: PIM and PIM 2 showed better discrimination and calibration than PRISM in a heterogeneous group of children in Spanish critical care units. However, these results should be confirmed in a larger study.

In cardiopulmonary resuscitation ages are divided in neonates (in the inmediate period after the birth), infant (from birth to 12 months) and child (from 12 months to puberty). Respiratory arrest is defined by the absence of spontaneous respiration (apnea) or a severe respiratory insufficiency (agonal gasping) that require respiratory assistance. Cardiac arrest is defined as the absence of central arterial pulse or signs of circulation (movement, cough or normal breathing) or the presence of a central pulse less than 60 lpm in a child who does not respond, not breath and with poor perfusion. After resuscitation the return of spontaneous circulation is defined as the recuperation of central arterial pulse or signs of circulation in a child with previous cardiorespiratory arrest. It is maintained when the duration is longer than 20 minutes. Injuries, sudden infant death syndrome, and respiratory diseases are the most frequent etiologies of cardiorrespiratory arrest in children. The prevention and the formation of citizens in basic cardiopulmonary resuscitation are the most effective measures to reduce the mortality of cardiorespiratory arrest in children.

Cardiopulmonary resuscitation does not end with restoration of spontaneous circulation; rather, it must be continued with the application of all the measures that allow organ function to be maintained. The initial goal of hemodynamic treatment is to achieve normal blood pressure for the patient's age by means of fluids and/or vasoactive drugs. The aim of respiratory treatment is to normalize ventilation and oxygenation without causing further lung injury, avoiding hyperoxia and hyperventilation as well as hypoxia and hypercapnia. Neurological stabilization aims to reduce secondary brain damage, by avoiding hypertension and hypotension, maintaining normal ventilation and oxygenation, and treating hyperglycemia, agitation and seizures. Although no specific studies in children are available, data from adults have shown that early moderate hypothermia attenuates brain damage secondary to cardiorespiratory arrest, without increasing complications. After the arrest, the need for analgesia and/or sedation must be considered. The process of transportation to the pediatric intensive care unit (PICU) requires the following steps: stabilizing the patient, checking for and stabilizing fractures and external wounds, ensuring a stable airway and intravenous lines, assessing the need for nasogastric and bladder tubes, taking blood samples for analyses, contacting the PICU and informing the staff about the child's condition, choosing the optimal vehicle for transportation according to the child's condition and the distance, checking pediatric equipment and medications, selecting experienced staff and, finally, maintaining close surveillance and monitoring during transportation.

Basic life support (BLS) is the combination of maneuvers that identifies the child in cardiopulmonary arrest and initiates the substitution of respiratory and circulatory function, without the use of technical adjuncts, until the child can receive more advanced treatment. BLS includes a sequence of steps or maneuvers that should be performed sequentially: ensuring the safety of rescuer and child, assessing unconsciousness, calling for help, positioning the victim, opening the airway, assessing breathing, ventilating, assessing signs of circulation and/or central arterial pulse, performing chest compressions, activating the emergency medical service system, and checking the results of resuscitation. The most important changes in the new guidelines are the compression: ventilation ratio and the algorithm for relieving foreign body airway obstruction. A compression/ ventilation ratio of 30:2 will be recommended for lay rescuers of infants, children and adults. Health professionals will use a compression: ventilation ratio of 15:2 for infants and children. If the health professional is alone, he/she may also use a ratio of 30:2 to avoid fatigue. In the algorithm for relieving foreign body airway obstruction, when the child becomes unconscious, the maneuvers will be similar to the BLS sequence with chest compressions (functioning as a deobstruction procedure) and ventilation, with reassessment of the mouth every 2 min to check for a foreign body, and evaluation of breathing and the presence of vital signs. BLS maneuvers are easy to learn and can be performed by anyone with adequate training. Therefore, BLS should be taught to all citizens.

Advanced life support (ALS) includes all the procedures and maneuvers used to restore spontaneous circulation and breathing, thus minimizing brain injury. The fundamental steps of ALS are airway control with adjuncts, ventilation with 100% oxygen, vascular access and fluid and drug administration, and monitoring to diagnose and treat arrhythmias. Airway control can be achieved by means of oropharyngeal airway, endotracheal intubation, and alternative methods (laryngeal mask and cricothyroidotomy). Vascular access can be achieved by the peripheral venous, intraosseous, central venous, and tracheal routes. The most frequent rhythms found in children with cardiorespiratory arrest are nonshockable (asystole, severe bradycardia, pulseless electrical activity, and complete atrioventricular block). In these cases, adrenaline continues to be the essential drug. Currently, low adrenaline doses (0.01 mg/kg IV and 0.1 mg/kg intratracheal administration) are recommended throughout the resuscitation period. Amiodarone (5 mg/kg) is the drug of choice in cases of ventricular fibrillation refractory to electric shock. The treatment sequence for shockable rhythms (ventricular fibrillation and pulseless ventricular tachycardia) is one 4 J/kg electric shock, followed by cardiopulmonary resuscitation (chest compressions and ventilation) for 2 minutes with subsequent reassessment of the electrocardiographic rhythm. Adrenaline must be administered immediately before the third electric shock and subsequently every 3-5 minutes. Amiodarone must be administered immediately before the fourth shock.

The Bispectral Index (BIS) is a single numeric value that indicates the depth of hypnosis by estimating the level of electrical activity in the brain through analysis of the frequency bands in the electroencephalogram. The BIS was primarily developed to monitor the level of hypnosis during surgery and has recently begun to be used in critically-ill patients. Currently, there is little experience of the BIS in critically-ill children. We present 6 cases that illustrate the utility of BIS monitoring in the PICU. We assessed sedation and analgesia during mechanical ventilation with and without neuromuscular block in two patients, and the effect of anesthetic agents during a surgical procedure in the PICU. The BIS was also useful in the continuous monitoring of the level of consciousness in a patient with encephalitis and in the early detection of brain death. Pacer-induced artefacts in the BIS value are also described. We conclude that BIS monitoring may be a useful, noninvasive method for assessing the level of hypnosis in critically-ill children.

OBJECTIVE: To analyze the characteristics and outcome of cardiorespiratory arrest secondary to trauma in children. PATIENTS AND METHODS: We performed a secondary analysis of data from a prospective, multicenter study of cardiorespiratory arrest in children. Data were recorded according to the Utstein style. Twenty-eight children (age range: 7 days to 16 years) with cardiorespiratory arrest secondary to trauma were evaluated. The outcome variables were return of spontaneous circulation, sustained (more than 20 minutes) return of spontaneous circulation (initial survival), and survival at hospital discharge (final survival) in relation to the characteristics of the cardiorespiratory arrest and cardiopulmonary resuscitation. Neurological and general performance outcome was assessed by means of the Pediatric Cerebral Performance Category scale and the Pediatric Overall Performance Category scale. RESULTS: Return of spontaneous circulation was obtained in 18 patients (64.2 %), initial survival was achieved in 14 (50 %) and final survival was achieved in three (10.7 %) (two without neurological sequelae and one with vegetative status). Final survival was significantly higher in patients with respiratory arrest (33.3 %) than in those with cardiac arrest (4.5 %), p = 0.04. Final survival was also higher in patients with a duration of cardiopulmonary resuscitation shorter than 20 minutes (27.2 %) than in the remaining patients (0 %), p =0.05. The two survivors without neurologic sequelae had respiratory arrest. CONCLUSIONS: Survival until hospital discharge in children with cardiorespiratory arrest secondary to trauma is lower than that in children with cardiorespiratory arrest. Patients with respiratory arrest when resuscitation is started and those with a duration of cardiopulmonary resuscitation of less than 20 minutes showed better survival than the remaining patients.

OBJECTIVE: To evaluate the impact on survival of intravenous or intraosseous high-dose epinephrine compared with standard doses in children with cardiorespiratory arrest. MATERIAL AND METHODS: We performed a multicenter, prospective study. Cardiopulmonary resuscitation data from 283 children was collected following international guidelines (Utstein style) over 18 months. In a secondary analysis we studied survival in 92 children who were treated with intravenous or intraosseous epinephrine. RESULTS: One or more conventional doses of epinephrine (0.01 mg/kg) were administered in 12 patients and a first conventional dose followed by one or more high doses (0.1 mg/kg) were administered in 80 patients. The age and weight of children in the conventional-dose group were higher than those in the high-dose group (97.1 +/- 70.5 months vs 29.9 +/- 36.9 months, p = 0.03 and 24.7 +/- 20.8 kg vs 11.9 +/- 8.9 kg, p = 0.037, respectively). The number of doses administered in the conventional-dose group was lower than that in the high-dose group (4 +/- 4 vs 5.4 +/- 3.4, p = 0.01). No significant differences were observed between the two groups in type of arrest, site of arrest, initial electrocardiographic rhythm, response to resuscitation attempts with return of spontaneous circulation, total resuscitation time, neurological status at the end of the episode and survival to hospital discharge and at 1-year of follow-up. CONCLUSION: Although the present study has considerable limitations, the results suggest that high doses of epinephrine do not improve survival in cardiorespiratory arrest in children.

A 4-year-old girl suffered severe postoperative chest tube drainage bleeding after cardiac transplant surgery requiring extracorporeal membrane oxygenation. Transfusions of platelets and fresh frozen plasma failed to decrease the bleeding. At 2.5 hours a dose of 180 mcg/kg of recombinant activated Factor VII was administered. The hemorrhage decreased from 45 ml/kg/h in the first 2.5 hours to 17 ml/kg/h in the next 2.5 hours. The same dose of recombinant activated Factor VII was administered and the hemorrhage suddenly decreased to 1.5 ml/kg/h in the next 2.5 hours, with subsequent disappearance. No adverse events related to activated Factor VII were observed. Recombinant activated Factor VII may be useful in some cases of severe postoperative bleeding in children after cardiac surgery. Randomized controlled studies are needed to confirm its safety and efficacy, and to evaluate the most suitable dose.
