Transcranial Doppler and NIRS Monitoring of Cerebral Hemodynamics in Pediatric Laparoscopic Surgery

Laparoscopic surgery has become increasingly common in pediatric patients due to its minimally invasive nature and favorable postoperative outcomes. However, the creation of pneumoperitoneum with carbon dioxide (CO₂) insufflation and the use of the Trendelenburg position may increase intra-abdominal pressure and potentially influence intracranial pressure and cerebral hemodynamics. These physiological changes may affect cerebral perfusion and oxygenation during surgery. This prospective observational study aims to evaluate cerebral hemodynamic changes during pediatric laparoscopic inguinal hernia repair using transcranial Doppler ultrasonography (TCD) and near-infrared spectroscopy (NIRS). Middle cerebral artery (MCA) flow velocities and pulsatility index (PI) will be measured with TCD as indirect indicators of intracranial pressure, and their relationship with cerebral oxygen saturation measured by NIRS will be assessed. In addition, mean arterial pressure and end-tidal CO₂ values will be recorded to evaluate their association with cerebral hemodynamic changes during different phases of surgery.

The study hypothesizes that a standardized follow-up path managed by an electronic platform will improve follow-up compliance and reduce the missed diagnosis rate of late effects.

Optimisation of Solute Removal and Water Usage in Paediatric Haemodialysis

Children receiving chronic haemodialysis are typically treated with dialysis machines designed for adult patients. As a result, some devices do not allow the ideal blood or dialysate flow rates to be set for paediatric use. In addition, the optimal dialysate-to-blood flow ratio for maximising solute removal while minimising water consumption remains poorly defined. The aim of this study is to quantify the dialyser extraction ratio and clearance across different dialysis modalities and a range of dialysate-to-blood flow ratios. Blood and dialysate samples are collected at the blood inlet, blood outlet, and dialysate outlet lines, and concentrations of various uraemic toxins-spanning a range of molecular weights-are measured to calculate solute clearances.

Comparison of Erector Spinae Plane Block and Caudal Block in Pediatric Patients Aged 1 to 8 Years Undergoing Lower Abdominal Surgery

In routine pediatric surgical practice, lower abdominal surgeries are commonly performed. Inadequate control of postoperative pain can hinder functional recovery and may lead to negative behavioral changes as well as parental dissatisfaction. Regional anesthesia techniques are widely recommended for pain management in pediatric surgery, as they reduce the need for parenteral opioids and improve the effectiveness of postoperative pain control, patient comfort, and parental satisfaction. Various nerve block techniques have been developed to enhance postoperative analgesia and facilitate recovery in pediatric patients. However, there is still no consensus regarding the most effective regional anesthesia strategy for pediatric surgical procedures. Among regional anesthesia techniques used for pain management in children undergoing lower abdominal surgery, caudal block remains the most commonly applied method. The introduction of real-time ultrasound guidance has improved the reliability and safety of caudal blocks. Nevertheless, a major limitation of this technique is its relatively short duration of action following a single injection, even when long-acting local anesthetics or adjuvant agents are used. Consequently, several fascial plane blocks, such as the quadratus lumborum block, transversus abdominis plane block, and rectus sheath block, have been proposed as alternative approaches for postoperative analgesia in children. The erector spinae plane block is a regional anesthesia technique that has been applied at thoracic, lumbar, cervical, and sacral levels for both acute and chronic pain management. By providing blockade of both somatic and visceral pain pathways, it has demonstrated effective postoperative analgesic properties in a variety of thoracic and abdominal surgical procedures. The technique involves the injection of a local anesthetic into the interfascial plane between the erector spinae muscle and the transverse process, allowing longitudinal spread of the anesthetic across multiple spinal levels. With a growing body of evidence supporting its feasibility and effectiveness, the erector spinae plane block has gained increasing attention in pediatric anesthesia practice. The aim of this study is to evaluate and compare the analgesic efficacy and safety of ultrasound-guided erector spinae plane block and caudal block in pediatric patients undergoing unilateral lower abdominal surgery under general anesthesia. The primary objective is to compare postoperative pain levels between the two techniques using the FLACC score, which assesses facial expression, leg position, activity, crying, and consolability. Secondary objectives include the evaluation of intraoperative heart rate, blood pressure, and oxygen saturation, block application times, parental satisfaction, and the incidence of postoperative side effects.

Amputations in Childhood and Neuropathic Pain

This observational study aims to assess the presence of neuropathic pain in children and adolescents who underwent limb amputation during childhood. The study focuses on two types of neuropathic pain: phantom limb pain and residual limb pain. It also evaluates quality of life and functional autonomy in this population and explores potential associations between neuropathic pain, autonomy, quality of life, and age at amputation. Using a mixed retrospective and prospective design, data are collected from medical records and standardized questionnaires administered during routine follow-up visits at a specialized pediatric limb anomaly center. The study seeks to improve understanding of neuropathic pain after pediatric amputation and its impact on daily functioning.

Which Rapid Sequence Induction Technique Should be Used in Urgent Surgery in Children?

The goal of our study is to compare classical Rapid Sequence Induction (RSI) and modified Rapid Sequence Induction (mRSI) in pediatric patients with a full stomach undergoing urgent surgical procedures.

Natural Course of Congenital Hydronephrosis in Infants Aged 0-6 Months

This project aims to systematically delineate the natural progression of congenital hydronephrosis diagnosed within the critical window of 0-6 months through a prospective, multicenter, observational cohort study. The focus will be on analyzing the resolution rates, progression rates, and influencing factors of hydronephrosis of varying severities based on the UTD grading system. Congenital hydronephrosis is one of the most common congenital urinary system abnormalities in children, with a high prenatal detection rate. However, its postnatal natural course is highly heterogeneous, leading to significant controversy in clinical management regarding follow-up intensity and intervention timing. Currently, there is a lack of prospective, large-sample, multicenter natural history data in China. By establishing a standardized follow-up system and collecting high-quality clinical and imaging data, this study aims to provide high-level evidence-based medical support for developing individualized and precise clinical management strategies, thereby reducing unnecessary interventions and delayed treatment. Consequently, conducting this multicenter study holds significant clinical and scientific value.

The Effect of Using Distractor Cards and Thermochromic Cards on Pain, Fear, Anxiety and Procedure Time in Children Receiving Inhaler Therapy

THE EFFECT OF USİNG DİSTRACTOR CARDS AND THERMOCHROMİC CARDS ON PAİN, FEAR, ANXİETY AND PROCEDURE TİME İN CHİLDREN RECEİVİNG INHALER THERAPY. Respiratory illnesses in children are a leading cause of childhood morbidity and mortality worldwide. Organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) report that millions of children are hospitalized each year due to respiratory illnesses (He, Wang, \& Zhang, 2025). A large proportion of these illnesses are caused by viral agents, and pathogens such as Respiratory Syncytial Virus (RSV), influenza, and rhinoviruses pose serious health threats to young children (Chen, Zhang, \& Li, 2024). This study will be one of the rare studies in pediatric nursing that examines the effectiveness of non-pharmacological interventions that can be applied during inhaler therapy in young age groups. The findings will contribute to nurses developing effective methods to reduce the negative emotions experienced by children during treatment. Furthermore, the first-ever use of thermochromic cards in this context in pediatric nursing will provide an innovative perspective on pediatric nursing practices. H0: Thermochromic cards and distraction cards used during inhaler therapy have no effect on pain, fear, anxiety levels, or processing time. Thermochromic cards used during inhaler therapy: H1: reduce the child's pain. H2: reduce the child's fear. H3: reduce the child's anxiety level. H4: shorten the child's processing time. Distraction cards used during inhaler therapy: H5: reduce the child's pain. H6: reduce the child's fear. H7: reduce the child's anxiety level. H8: shorten the child's processing time.

Comparing How Burn Wounds and Scars Heal in Children Using Chitosan and Silver Dressings

Burns are among the most common types of trauma worldwide, ranking fourth after traffic accidents, falls, and violence, and account for an estimated 265,000 deaths annually (WHO). Most burn injuries result from heat exposure, though other causes include friction, chemicals, and electricity. Effective burn treatment aims to promote wound healing by supporting tissue regeneration and maintaining optimal conditions such as moisture, oxygenation, and low bacterial load. In Slovenia and across Europe, silver-based dressings are commonly used for burn care. While they are known to support wound healing, their effectiveness in reducing scar formation remains unclear. Chitosan-based hydrogels, by contrast, offer promising benefits due to their natural biocompatibility, antibacterial action, and support for tissue repair, though clinical data are still limited. This study aims to compare the effectiveness of chitosan-based and silver-based dressings in burn wound healing, focusing on healing time, scar formation, cost-efficiency, and patient experience. Scar outcomes will be assessed using the validated POSAS (Patient and Observer Scar Assessment Scale).
