Thrombocytopenia and bleeding are common complications of hematologic malignancies. Often, prophylactic platelets are administered to minimize bleeding risk, based on total platelet count (TPC). However, TPC is a poor predictor, and does not provide rapid information.

Management of the difficult paediatric airway is challenging due to anatomical differences, congenital anomalies, paucity of paediatric airway management algorithms, and the limited availability of paediatric-sized airway devices. In this case report, we describe two cases highlighting the potential use of seemingly oversized videolaryngoscopes in the management of the difficult paediatric airway. Recognising the cause of difficult airway in the paediatric population is potentially useful in the selection of a larger videolaryngoscope blade to aid laryngoscopy and intubation.

Intelligent systems are transforming the world, as well as our healthcare system. We propose a deep learning-based cough sound classification model that can distinguish between children with healthy versus pathological coughs such as asthma, upper respiratory tract infection (URTI), and lower respiratory tract infection (LRTI). To train a deep neural network model, we collected a new dataset of cough sounds, labelled with a clinician's diagnosis.

Background: Transfer into the operating room, onto the operating table and mask induction of anaesthesia are major challenges faced by children with Autistic Spectrum Disorder (ASD). In a pilot study, parents observed that perioperative transfer becomes unsafe and difficult when children with ASD becomes uncooperative.

Method: A CHILD-KIND CONCEPT mobility system comprising of multi-positioning seat configurations and restraining module was developed with inputs from multi-disciplinary healthcare professionals and parents with children with ASD.

Cough is a common symptom presenting in asthmatic children. In this investigation, an audio-based classification model is presented that can differentiate between healthy and asthmatic children, based on the combination of cough and vocalised /ɑ:/ sounds. A Gaussian mixture model using mel-frequency cepstral coefficients and constant-Q cepstral coefficients was trained.

Children with autistic spectrum disorder (ASD) often exhibit uncontrollable disruptive behaviour during transfer to the operating room and operating table and at the induction of anaesthesia (sleep). This process often involves the physical restraining of children. These children are then lifted onto the operating table by healthcare staff after being anaesthetized.

A force sensor system was developed to give real-time visual feedback on a range of force. In a prospective observational cross-section study, twenty-two anaesthesia nurses applied cricoid pressure at a target range of 30-40 Newtons for 60 seconds in three sequential steps on manikin: Group A (step 1 blinded, no sensor), Group B (step 2 blinded sensor), Group C (step 3 sensor feedback). A weighing scale was placed below the manikin.

Background: The Auditory brainstem implant (ABI) is a new surgical option for hearing impaired children. Intraoperative neurophysiology monitoring includes brainstem mapping of cranial nerve (CN) IX, X, XI, XII and their motor nuclei, and corticobulbar tract motor-evoked potential. These require laryngeal electrodes and intra-oral pins, posing a challenge to airway management especially in the pediatric airway, where specialized electromyogram (EMG) tracheal tubes are not available.

Peripheral nerve injury following the use of arterial tourniquets is a rare but potentially debilitating complication. Further education on the safe and appropriate practice of tourniquets is imperative to reduce the incidence of tourniquet-related complications.

Introduction: The efficiency of postoperative handover of paediatric patients to the children's intensive care unit (CICU) varies according to institutions, clinical setup and workflow. Reorganisation of handover flow based on findings from observational studies has been shown to improve the efficiency of information transfer. This study aimed to evaluate a new handover process based on recipients' perceptions, focusing on completeness and comprehensiveness of verbal communication, and the usability of a situation, background, assessment and recommendation (SBAR) form.

Purpose: To describe a practical method of aiding nasotracheal intubation in a cleft palate patient with previous pharyngoplasty using a suction catheter under tactile guidance. Problems of airway management in these patients are also discussed.

Clinical Features: A 26-yr-old woman presented for elective Le Fort maxillary osteotomy.

Background: EMLA cream is the current technique of choice to reduce pain during venous cannulation in most paediatric practice. Its use is limited by logistic arrangements and failure to improve cooperation and allay anxiety. Nitrous oxide (N2O) would appear to be an effective alternative.

Background: [corrected] Volumetric infusion pumps are widely used in paediatric practice. Tissue extravasation is a hazard. The occlusion pressure limit alarm, although not intended to detect extravasation, is the only warning sign present to indicate flow faults in the infusion systems.
