COVID-19 in Pediatric Intensive Care Units in Poland, PAPITCO-19 Study (Polish Analysis of PICU Trends during COVID-19).

BACKGROUND: Children suffering from COVID-19 constitute about 10% of the entire population infected with the virus. In most of them, we observe asymptomatic or mild courses; however, about 1% of affected children require a stay in a paediatric intensive care unit (PICU) due to the course of the disease becoming severely life-threatening. The risk of respiratory failure, as with adults, is associated with the coexistence of concomitant diseases. The aim of our study was to analyse patients admitted to PICUs due to the severe course of their SARS-CoV-2 infection. We studied epidemiological and laboratory parameters, as well as the endpoint (survival or death). METHODS: A retrospective multi-centre study, the analysis covered all children with a confirmed diagnosis of SARS-CoV-2 virus infection who were admitted to PICUs in the period from November 2020 to August 2021. We studied epidemiological and laboratory parameters, as well as the endpoint (survival or death). RESULTS: The study analysed 45 patients (0.075% of all children hospitalised in Poland due to COVID-19 at that time). Mortality calculated in the entire study group was 40% (n = 18). Statistically significant differences between the compared groups (survived and died) concerned the parameters of the respiratory system. Lung Injury Score and the Paediatric Sequential Organ Failure Assessment were used. A significant correlation between disease severity and the patient's prognosis was shown by the liver function parameter AST (p = 0.028). During the analysis of patients requiring mechanical ventilation and assuming survival as the primary outcome, a significantly higher oxygen index on the first day of hospitalisation, lower pSOFA scores and lower AST levels (p: 0.007; 0.043; 0.020; 0.005; 0.039, respectively) were found. CONCLUSIONS: As with adults, children with comorbidities are most frequently at risk of severe SARS-CoV-2 infection. Increasing symptoms of respiratory failure, the need for mechanical ventilation and persistently high values of aspartate aminotransferase are indicators of poor prognosis.

Population Pharmacokinetic-Pharmacodynamic Modeling and Probability of Target Attainment Analysis of Rocuronium and Sugammadex in Children Undergoing Surgery.

BACKGROUND AND OBJECTIVES: Probability of target attainment (PTA) curves are commonly used to support dose recommendations of antibiotics for different patient groups. In this study we propose PTA analysis to optimize sugammadex dosing in children. METHODS: This study involved data from an observational cohort study of 30 American Society of Anesthesiologists (ASA) Physical Status I and II children undergoing surgery requiring muscle relaxation. All patients received 0.6 mg/kg rocuronium, with sugammadex administered at the end of surgery in three different doses (0.5, 1.0, and 2.0 mg/kg) to reverse the neuromuscular blockade. RESULTS: The data were analyzed using a population Bayesian-based approach. The developed model was used to simulate pharmacokinetic-pharmacodynamic profiles for different patient groups and dosing regimens before the PTA analysis was performed to translate these simulations into a clinically useful measure. The target was defined as neuromuscular blockade reversal measured by Train-of-Four (TOF ratio > 90%) at 1.5, 3, and 5 min post sugammadex dose. The sugammadex doses leading to 90% PTA were determined for different patients' body weights, rocuronium doses, and time gaps between rocuronium and sugammadex administration assuming the model, priors, and gathered data. For comparison, PTA curves for a range of clinical scenarios are provided to illustrate the usefulness of PTA analysis in selecting the appropriate dose for a given patient. CONCLUSIONS: The proposed PTA analysis is useful to support the sugammadex dose selection in different clinical scenarios. TRIAL REGISTRATION: The study was registered by ClinicalTrials.gov under number NCT04851574 on 21 April 2021.

Guidelines for treatment of acute pain in children - the consensus statement of the Section of Paediatric Anaesthesiology and Intensive Therapy of the Polish Society of Anaesthesiology and Intensive Therapy.

RATIONALE AND SCOPE OF THE GUIDELINES Pain is a subjective unpleasant sensory and emotional experience. Acute pain occurs irrespective of age and has a prevalence of about 5% of the general population. Surgical procedures and painful diagnostic procedures are the main causes of this unpleasant and dangerous phenomenon for hospitalized children. It should be remembered that maintaining homeostasis in a child undergoing surgery is also affected by provision of an adequate level of analgesia and sedation as well as nerve conduction block within the surgical site. Even though both paediatric anaesthesiologists and paediatric surgeons know that the therapeutic activities during the perioperative period should be focused on ensuring sufficient analgesia and haemodynamic stability in surgical patients, as many as 70% of children undergoing surgery may experience moderate to severe pain [1-7]. Moreover, pain management is one of the fundamental human rights, i.e. the right to relief of suffering. According to the declaration of the 13th World Congress on Pain in Montreal (September 2010), this right also includes children [8, 9]. In Poland, the law was amended in 2017, and now each patient is guaranteed the right to relief and treatment of pain (Journal of Laws of 2017, item 836). Unfortunately, this right is not always respected in paediatric patients. Many factors contribute to ineffective analgesia in paediatric patients, mainly insufficient knowledge and lack of experience (concerning the use of opioids in particular), as well as lack of management standards, the negative attitude of the personnel or poor organization [10-13]. In hospitals which, as a result of organizational changes, have implemented analgesic treatment regimens and regularly educate their personnel in these issues, both efficiency and effectiveness of pain relief in children are high [14]. For many years, Polish paediatric anaesthesio-logists have been promoting and streamlining the analgesic management of children, which has led to the development of the present publication. The regimens presented in it are based on both the latest medical reports and many years of the authors' experience. The classes of recommendations and levels of evidence have been prepared (Tables 1 and 2, respectively). The presented recommendations were formulated based on a survey of medical reports published in the last two decades.

Clinical Picture and Risk Factors of Severe Respiratory Symptoms in COVID-19 in Children.

Children with COVID-19 develop moderate symptoms in most cases. Thus, a proportion of children requires hospital admission. The study aimed to assess the history, clinical and laboratory parameters in children with COVID-19 concerning the severity of respiratory symptoms. The study included 332 children (median age 57 months) with COVID-19. History data, clinical findings, laboratory parameters, treatment, and outcome, were evaluated. Children were compared in the groups that varied in the severity of symptoms of respiratory tract involvement. Children who required oxygen therapy represented 8.73%, and intensive care 1.5% of the whole cohort. Comorbidities were present in 126 patients (37.95%). Factors increasing the risk of oxygen therapy included comorbidities (odds ratio (OR) = 92.39; 95% confidence interval (95% CI) = (4.19; 2036.90); p < 0.00001), dyspnea (OR = 45.81; 95% CI (4.05; 518.21); p < 0.00001), auscultation abnormalities (OR = 34.33; 95% CI (2.59; 454.64); p < 0.00001). Lactate dehydrogenase (LDH) > 280 IU/L and creatinine kinase > 192 IU/L were parameters with a good area under the curve (0.804-LDH) and a positive predictive value (42.9%-CK). The clinical course of COVID-19 was mild to moderate in most patients. Children with comorbidities, dyspnea, or abnormalities on auscultation are at risk of oxygen therapy. Laboratory parameters potentially useful in patients evaluated for the severe course are LDH > 200 IU/L and CK > 192 IU/L.

Flip-Flop Phenomenon in Epidural Sufentanil Pharmacokinetics: A Population Study in Children and Infants.

The aims of this study were to develop a population pharmacokinetic model of sufentanil coadministered with 0.2% ropivacaine as an epidural infusion in infants and describe the sufentanil absorption profile from epidural space. Data from 2 previously published studies were merged for analysis-20 infants aged 3-36 months receiving sufentanil as an epidural infusion and 41 children 0-17 years old receiving sufentanil as a long-term intravenous infusion. A population nonlinear mixed-effects model was built in NONMEM. Sufentanil pharmacokinetics were described by a 2-compartment model with first-order absorption. The effect of body size on all volume and clearance parameters was included in the model according to allometric scaling with theoretical exponents. The maturation process of metabolic clearance was described by the Hill model. During the model-building process the population was divided into 2 fractions with different typical values of metabolic clearance (CL1 and CL2). The typical values of systemic clearance scaled to a 70-kg patient for the 2 subpopulations were CL1 = 52.6 L/h and CL2 = 158 L/h. The parameters of the Hill function were 54.9 weeks for the postmenstrual age of 50% clearance maturation and 0.802 for the Hill coefficient. The typical values of distribution clearance and volumes of the central and peripheral compartments for a patient with a weight of 70 kg were Q = 40.5 L/h, VC = 7.63 L, and VT = 473 L, respectively. The value of the absorption rate constant from the epidural space was 0.0459/h, which suggests flip-flop pharmacokinetics of sufentanil after epidural administration.

The pharmacokinetics of dexmedetomidine during long-term infusion in critically ill pediatric patients. A Bayesian approach with informative priors.

The purpose of this study was to assess the pharmacokinetics of dexmedetomidine in the ICU settings during the prolonged infusion and to compare it with the existing literature data using the Bayesian population modeling with literature-based informative priors. Thirty-eight patients were included in the analysis with concentration measurements obtained at two occasions: first from 0 to 24 h after infusion initiation and second from 0 to 8 h after infusion end. Data analysis was conducted using WinBUGS software. The prior information on dexmedetomidine pharmacokinetics was elicited from the literature study pooling results from a relatively large group of 95 children. A two compartment PK model, with allometrically scaled parameters, maturation of clearance and t-student residual distribution on a log-scale was used to describe the data. The incorporation of time-dependent (different between two occasions) PK parameters improved the model. It was observed that volume of distribution is 1.5-fold higher during the second occasion. There was also an evidence of increased (1.3-fold) clearance for the second occasion with posterior probability equal to 62 %. This work demonstrated the usefulness of Bayesian modeling with informative priors in analyzing pharmacokinetic data and comparing it with existing literature knowledge.

Ketamine Anesthesia, Efficacy of Electroconvulsive Therapy, and Cognitive Functions in Treatment-Resistant Depression.

OBJECTIVES: Electroconvulsive therapy (ECT) is the most effective treatment for drug-resistant depression (DRD). Because a single infusion of ketamine may exert both a rapid antidepressant effect and a quick improvement of cognition, the aim of the present study was to assess whether ketamine, as an anesthetic drug for ECT, can augment the antidepressant activity of the procedure and/or exert a beneficial effect on cognition. METHODS: A total of 11 male and 34 female patients with DRD, aged 21 to 75 years, were included in the study. Fifteen patients (group 1) received only thiopental anesthesia, 15 patients (group 2) had their second and third ECT sessions with ketamine, and 15 patients (group 3) had ketamine for the second, fourth, sixth, eighth, and tenth sessions. Depression intensity was measured by the 17-item Hamilton Depression Rating Scale. Cognitive functions were measured before and after ECT, assessing visual-spatial abilities, verbal auditory memory, working memory, and executive functions. RESULTS: Before the ECT, the mean (SD) intensity of depression was 32 (6) points on the Hamilton Depression Rating Scale and the mean number of ECT sessions was 10.8 (1.5), with no difference between groups. After the last ECT session, the intensity of depression was significantly lower in group 3, compared with group 1. Cognitive assessments after ECT showed a more marked worsening in verbal memory in patients with added ketamine anesthesia. CONCLUSIONS: The addition of ketamine may be connected with better antidepressant efficacy of ECT, compared with only thiopental anesthesia. However, patients with added ketamine had worse results on some of the indices measuring verbal memory.

Pharmacokinetics of sufentanil during long-term infusion in critically ill pediatric patients.

The aim of this study was to develop a population pharmacokinetic model of sufentanil and to assess the influence of covariates in critically ill children admitted to a pediatric intensive care unit. After institutional approval, 41 children were enrolled in the study. Blood samples for pharmacokinetic (PK) assessment were collected from routinely placed arterial catheters during and after discontinuation of infusion. Population nonlinear mixed-effects modeling was performed using NONMEM. A 2-compartment model described sufentanil PK sufficiently. Typical values of the central and peripheral volume of distribution and the metabolic and intercompartmental clearance for a theoretical patient weighing 70 kg were VC = 7.90 l, VT = 481 L, Cl = 5.3 L/h, and Q = 38.3 L/h, respectively. High interindividual variability of all PK parameters was noted. Allometric/isometric principles to scale sufentanil PK revealed that to achieve the same steady-state sufentanil concentrations in plasma for pediatric patients of different body weights, the infusion rate should follow the formula (infusion rate for a 70-kg adult patient, µg/h) × (body weight/70 kg)(0.75). Severity of illness described by PRISM score, the monitored physiological and laboratory parameters, and coadministered drugs such as vasopressors were not found to be significant covariates.

Adverse reaction to ceftriaxone in a 28-day-old infant undergoing urgent craniotomy due to epidural hematoma: review of neonatal biliary pseudolithiasis.

The debate as to whether to administer ceftriaxone to neonates is likely to continue. Ceftriaxone has numerous advantages for critically ill pediatric patients. However, it is also known to contribute substantially to the development of biliary pseudolithiasis. Although pediatric patients rarely develop gallbladder disorders, this complication may lead to adverse events in high-risk patients with predisposing factors, particularly in neonates and infants treated with ceftriaxone. In this paper we present an interesting case report of a 28-day-old neonate with spontaneous severe epidural hematoma who developed biliary pseudolithiasis related to the use of ceftriaxone. We also discuss the efficacy of ceftriaxone in neonates and infants. Neonatologists and pediatric intensivists should be aware of the higher risk of co-existence of hyperbilirubinemia and gallbladder disorders while using ceftriaxone in pediatric settings.

Endovascular treatment of an adolescent patient with a ruptured intracranial aneurysm - case report and review of literature.

BACKGROUND: The occurence of aneurysms in young patients, under 18 years of age, is estimated at 0.5-2% of all diagnosed aneurysms. CASE REPORT: We reported on a case of a 16-year-old patient with subarachnoid hemorrhage diagnosed due to a ruptured cerebral vessel aneurysm. The angio-CT revealed an aneurysm of the middle cerebral artery, in its distal branch. An ad hoc coil embolization was performed with angiographic success. After 6 months following the ictus, the patient underwent a control angiography which confirmed total occlusion of the aneurysm with no residual inflow. Clinical examination revealed no neurological deficits and the patient was rated 0 in mRS (modified Rankin Scale). CONCLUSIONS: In experienced departments of interventional neuroradiology the endovascular treatment should be the treatment of choice.

Pharmacokinetics and pharmacodynamics of propofol in children undergoing different types of surgeries.

BACKGROUND: Propofol is a commonly used agent in total intravenous anesthesia (TIVA). However, the link between its pharmacokinetics and pharmacodynamics has not been fully characterized in children yet. Our aim was to determine the quantitative relationship between the venous plasma concentration and bispectral index (BIS) effect in a heterogeneous group of pediatric patients undergoing various surgical procedures (ASA status I-III). METHODS: Nine male and nine female patients were anesthetized with propofol-fentanyl TIVA. Sparse venous samples for propofol concentrations assay and dense BIS measurements were collected during and after the end of infusion. Nonlinear mixed-effect modeling in NONMEM was used for data analysis. RESULTS: A three-compartment model was linked with a classical Emax model through a biophase compartment to describe the available data. All clearance and volume terms were allometrically scaled to account for the body mass difference among the patients under study. A typical patient had their PK parameters observed within the range of literature values for children. The pharmacodynamic parameters were highly variable. The EC50 of 2.80 mg/L and the biophase distribution rate constant of 3.33 min(-1) were found for a typical patient. CONCLUSIONS: The BIS values in children are highly correlated with the propofol effect compartment concentrations according to the classical Emax concentration-response relationship. Children had slightly lower sensitivity to propofol and slightly higher clearance, as compared with the adult data available in literature. The intra-patient variations in the BIS require the anesthesiologist's attention in using BIS values alone to evaluate the depth of anesthesia in children.

Procedural sedation and analgesia in children undergoing digestive endoscopic procedures - paediatrician or anaesthesiologist?

Endoscopic procedures of the gastrointestinal tract were successfully introduced into paediatric practice in the 1970s. Recent expansive development has become useful for improvement of both diagnosis and treatment in many children with gastrointestinal diseases. Most of these procedures are performed under procedural sedation (PSA) knowing anatomical, physiological and psychological differences and requiring good experience from the paediatrician and anaesthesiologist. These principles help to provide the procedure safely and minimise adverse events, which are greater the smaller the child is. Procedural sedation and analgesia in healthy children can be performed by a paediatrician, but children with congenital defects and serious coexisting diseases (ASA ≥ III) and also during the usage of anaesthetics (e.g. propofol), should be managed by an anaesthesiologist.

Do we really know the pharmacodynamics of anaesthetics used in newborns, infants and children? A review of the experimental and clinical data on neurodegeneration.

The practices of anaesthesiology and intensive therapy are difficult to imagine without sedation or general anaesthesia, regardless of whether the patient is a newborn, baby, child or adult. The relevant concerns for children are distinct from those for adults, primarily due to the effects of anatomical, physiological and pharmacokinetic-pharmacodynamic (PK/PD) differences, which become increasingly important in the brains of children as they develop. The process of central nervous system maturation in humans lasts for years, but its greatest activity (myelination and synaptogenesis) occurs during the fetal period and the first two years of life. Many experimental studies have demonstrated that exposure to anaesthetic drugs during this period can induce neurodegenerative changes in the central nervous systems of animals. The extrapolation of these results directly to humans must be performed with great caution, but anaesthesiologists around the world must begin to debate the safety of general anaesthesia in humans. Prospective trials should continue being carried out, and anaesthesia and surgery, delayed if possible among the smallest patients. The simultaneous use of different anaesthetics with the same potential neurotoxicities should also be avoided, potentially in favour of regional anaesthesia techniques, in this group of patients.

Procedural sedation and analgesia for gastrointestinal endoscopy in infants and children: how, with what, and by whom?

Endoscopic procedures involving the gastrointestinal tract have been successfully developed in paediatric practice over the last two decades, improving both diagnosis and treatment in many children's gastrointestinal diseases. In this group of patients, experience and co-operation between paediatricians/endoscopists and paediatric anaesthesiologists should help to guarantee the quality and safety of a procedure and should additionally help to minimise the risk of adverse events which are greater the smaller the child is. This principle is more and more important especially since the announcement of the Helsinki Declaration on Patient Safety in Anaesthesiology in 2010, emphasising the role of anaesthesiology in promoting safe perioperative care. The Helsinki Declaration has been endorsed by all European anaesthesiology institutions as well as the World Health Organisation's 'Safe Surgery Saves Lives' initiative including the 'Surgical Safety Checklist'. Although most of these procedures could be performed by paediatricians under procedural sedation and analgesia, children with congenital defects and serious coexisting diseases (ASA ≥ III) as well as the usage of anaesthetics (e.g. propofol) must be managed by paediatric anaesthesiologists. We have reviewed the specific principles employed during qualification and performance of procedural sedation and analgesia for gastrointestinal endoscopy in paediatrics. We have also tried to answer the questions as to how, with what, and by whom, procedural sedation for gastrointestinal endoscopy in children should be performed.

Efficacy of plasma exchange in septic shock: a case report.

The mortality rate for severe sepsis and septic shock remains high. Additionally, this life-threatening state poses serious difficulties for the treatment of patients. Unfortunately, the mechanism of sepsis is complex and not well understood. In this paper, we present the case of a 2.5-year-old female with septic shock treated with plasma exchange (PE) as a nonstandard therapy. We analysed the medical history of disease, including patient data, physical examination, laboratory tests and treatment. Unexpectedly, we achieved clinical improvement after the first PE. During PE, the dose of catecholamine was reduced. In addition, the level of C-reactive protein seemed to be a better predictor of the efficacy of PE in septic shock compared to procalcitonin. We conclude that PE may improve the survival rate for patients with septic shock. These data could be useful in the search and introduction of new or alternative methods of treatment for critically ill children.

Assessing circadian rhythms during prolonged midazolam infusion in the pediatric intensive care unit (PICU) children.

BACKGROUND: This study evaluates possible circadian rhythms during prolonged midazolam infusion in 27 pediatric intensive care unit (PICU) children under mechanical ventilation. METHODS: Blood samples for midazolam and 1-OH-midazolam assay were collected throughout the infusion at different times of the day. The blood pressure, heart rate and body temperature were recorded every hour for the rhythms analysis. Population nonlinear mixed-effect modeling with NONMEM was used for data analysis. RESULTS: A two-compartment model for midazolam pharmacokinetics and a one-compartment model for midazolam metabolite adequately described the data. The 24 h profiles of all monitored physiological parameters were greatly disturbed/abolished in comparison with the well-known 24 h rhythmic patterns in healthy subjects. There was no significant circadian rhythm detected with respect to midazolam pharmacokinetics, its active metabolite pharmacokinetics and all monitored parameters. CONCLUSIONS: We concluded that the light-dark cycle did not influence midazolam pharmacokinetics in intensive care units children. Also, endogenous rhythms in critically ill and sedated children are severely disturbed and desynchronized. Our results confirmed that it is necessary to adjust the dose of midazolam to the patient's body weight. The low value of midazolam clearances observed in our study was probably caused by mechanical ventilation, which was shown to decrease the cardiac output.

A survey of anaesthesiology residents' knowledge of resuscitation guidelines.

BACKGROUND: Several surveys have been published, documenting the lack of knowledge of cardiopulmonary resuscitation (CPR) among anaesthesiology residents. As a result, we decided to assess the competency of local trainees in basic and advanced CPR. METHODS: The survey was conducted among 26 residents in anaesthesiology who were asked twice (at the beginning, and at the end of refresher courses) to complete an open test on adult and paediatric CPR guidelines. RESULTS: The results in the first, introductory surveys were poor. Most of the wrong answers concerned the age borderline between an adult and a child; the correct CPR sequences and their modification in children; and paediatric medication. The respondents were not able to define all reversible causes of cardiac arrest. The second survey were somewhat better, but the respondents could still not name the correct lidocaine dosage in all age groups. CONCLUSIONS: Residents in anaesthesiology show the tendency their knowledge of resuscitation guidelines to decay. Refresher life support courses should be mandatory for this group of physicians.

[A survey of basic resuscitation knowledge among medical personnel of a paediatric hospital]. / Personel medyczny szpitala pediatrycznego nie ma wystarczajacej wiedzy dotyczacej prowadzenia bezprzyrzadowej resuscytacji krazeniowo-oddechowej.

BACKGROUND: The European Resuscitation Council (ERC) algorithms for cardiopulmonary resuscitation have undergone many changes, the latest version being published in 2005.To establish the level of general knowledge of resuscitation algorithms, we audited physicians and nurses in a tertiary paediatric hospital. METHODS: The audit was performed among 64 physicians and 54 nurses. They were allocated to the following subgroups: surgeons, paediatricians, surgical nurses, and non-surgical nurses. A written open examination was conducted, containing response questions on basic resuscitation of adults, children and infants. The participants also completed a questionnaire concerning their knowledge of current guidelines and their activity in continuing education. RESULTS: The vast majority of those audited were not familiar with the 2005 ERC guidelines. Most of the physicians and nurses were not able to differentiate between an adult and a child.They did not know the recommended number of artificial breaths to be delivered to a patient with preserved cardiac function, or the number of resuscitation cycles (delivered by one or two rescuers). They could not describe the open airway manoeuvres and volumes of artificial breaths. Depending on subgroups, only 14.3-84.6% of participants knew how to deliver chest compressions to adults, 21.4-80.8% knew how to deliver them to children, and 19.2-75.4% knew how to deliver them to infants. 17.8-23.1% of nurses and 28.6-47.4% of physicians had completed basic life support courses. 0-14.3% of nurses and few physicians declared a familiarity with the 2005 guidelines, but only 35% of them were aware of the latest modifications. CONCLUSION: The medical staff of a paediatric hospital was not adequately trained in cardiopulmonary resuscitation and their knowledge about current recommendations was minimal. The authors suggest that life support courses should be mandatory for all physicians and nurses.

[Medical personnel in a paediatric hospital do not possess adequate cardiopulmonary resuscitation skills]. / Personel medyczny szpitala pediatrycznego nie ma wystarczajacych umiejetnosci prowadzenia resuscytacji krazeniowo-oddechowej.

BACKGROUND: The main changes to the European Resuscitation Guidelines in 2005 were relate to the tidal volume of artificial breaths, the position and depth of chest compressions, and th number of resuscitation cycles. To find out if these guidelines were widely known, we assessed the knowledge and skills of physicians and nurses working in a paediatric hospital. METHODS: During practical sessions, the skills of 118 employees (64 physicians and 54 nurses) were assessed when performing resuscitation on adult, child and infant AMBU manikins. Additionally, all participants completed self-assessment questionnaires. RESULTS: The main fault was the inadequate checking of the airway in adults. Only 53.6% of physicians and 71.9% of nurses could properly open the airway, and 85.7% of physicians and 50.0% of nurses correctly placed their heads above the victim's face when observing chest movements. Nearly 45% of nurses, and 100% of physicians delivered the correct tidal volume to adults, however it was frequently associated with marked gastric distension, in both adults and infants. The participants usually positioned their hands or fingers correctly on the manikin's chest, but delivered slow and shallow compressions. Almost 50% of participants graded their skills as inadequate. CONCLUSION: Despite continuous education, the resuscitation skills of physicians and nurses from a paediatric hospital were far from satisfactory. The results indicate an urgent need for regular training.
