This article analyzes the influence of interhospital transportation duration of newborns in critical state on the close outcome. The features of intensive care measures, the frequency of seizures, bronchopulmonary dysplasia and open arterial duct were studied regarding the age at which an infant was admitted to a neonatal ICU in a hospital of III level. It was found that transportation of critically ill infants at the age of one day or three days of life was associated with high risk of complications in the neonatal period. It was shown that the optimal time for interhospital transportation of a newborn baby to an intensive care unit of a hospital of III level is the second day after birth.

Methotrexate (MTX) is a widely used anti-tumor drug, folic acid antagonists. The effectiveness of high doses (more than 1 g/m2) of MTX in a monotherapy or in a combination with other chemotherapeutic drugs has been proven in a treatment of a large spectrum of oncological diseases in children such as osteosarcoma, tumors of the central nervous system, lymphomas, acute lymphoblastic leukemia. The use of high doses of MTX is often fraughted with development of life-threatening complications such as MTX-induced acute kidney injury, neurotoxicity, myelosuppression. Currently developed recommendations for therapeutic monitoring and supportive care, including hyper-hydration, urine alkalization and leucovorin therapy, allow to reduce toxicity of MTX, but in some patients it is not always possible to prevent the development of complications. Cohort studies in order to identify risk factors for toxicity after high doses of MTX in children with different forms of cancer are limited, as well as comparing various types of supportive care regimens, including, infusion therapy. Studying of development mechanisms of MTX toxicity depending on background conditions will allow to improve existing recommendations and develop new and most effective standards of supportive therapy with respect to the individual specifics of patients.

Postpartum depression (PPD) is a significant mental health and social problem. A prospective cohort single-center study was conducted in Saint Petersburg, Russia from March 2015 to October 2016 to assess the prevalence of PPD and possible serological markers associated with PPD. After exclusion of patients with a corresponding premorbid background and/or significant risk factors, prevalence rates were 9.6% on days P2 to P5. When comparing biochemical markers in patients with PPD (n = 37) and in healthy individuals (n = 72), a significant increase in the level of thyroid-stimulating hormone (3.36 ± 0.52 vs 1.98 ± 0.71 μIU/ml, p < 0.05), an increase in the level of marinobufagenin (0.928 ± 0.156 vs 0.462 ± 0.111 nM, p < 0.05), and a decrease in the activity of red-blood-cell Na+/K+-ATPase (1.68 ± 0.192 vs 2.39 ± 0.19 μM fn/ml/h, p < 0.03) were found.

Acute poisoning in children is one of the most frequent reasons for seeking medical care and hospitalization in intensive care units, but it is extremely rare in children of the first year of life. On the example of the clinical case, the peculiarities of the course of acute severe methadone poisoning in a two-month-old child against the background of natural feeding are considered. The main data of history and clinical-laboratory examination are reflected, which allowed to suspect acute poisoning in a timely manner and to carry out reasonable intensive therapy, against the background of which the maximum rapid improvement of the child s condition is achieved. The algorithm of differential diagnosis of comatose state in children is presented, which can be used in all cases of sudden suppression of consciousness of unclear genesis. Special attention is paid to the need for maximum early recognition of exogenous poisoning and targeted pathogenetic treatment aimed at elimination of toxicant metabolites. A distinctive feature of this case was the severe course of acute methadone poisoning in the infant with the development of coma and respiratory distress, which regressed against the background of the treatment carried out with the full recovery of the patient.

The article provides an overview of modern methods of sedation and analgesia during therapeutic and diagnostic manipulations in children, indicates indications and contraindications. Special attention is paid to the assessment of sedation and anaesthesia effectiveness, scales used for this purpose in children of different ages are described, criteria of sedation depth are given, equipment and measures necessary to ensure patient safety during manipulation are described. It has been noted that BIS index values correlate with sedation scales in children and adults, but values that determine deep sedation in children are currently not clearly defined, which requires further research. Drugs for sedation, their main characteristics and limitations for use are presented. The differences between sedation and monitored anesthesiology care (MAC), which can be provided only by a qualified anesthesiologist, are described in detail. It has been demonstrated that monitored anesthesiologic care implies deep sedation with control of vital functions, control of breathing and hemodynamics during manipulation, and it is noted that capnography is a mandatory element of monitoring in this type of anesthesiologic care in order to detect apnea as early as possible. Criteria for recovery of consciousness after completion of sedation are specified, which include normal airway, adequate ventilation, stability of hemodynamic, restoration of initial level of consciousness, motor activity and possibility to receive liquids through mouth in absence of vomiting. It is noted that the average time from the end of procedural sedation to the restoration of the original state is about 2 hours.
