Delayed ventricular fibrillation following blunt chest trauma in a 4-year-old child.

A 4-year-old boy who was involved in a motor vehicle accident as a pedestrian and suffered blunt chest trauma was admitted to the emergency room. Unpredictable delayed ventricular fibrillation was diagnosed and treated successfully 2 h later. This case cannot be classified as commotio cordis as the ventricular fibrillation (VF) developed so long after the sustained chest injury. At the same time, other possible etiologies of VF such as cardiac pathology or electrolyte and metabolic disorders had been ruled out. Thus, an etiological link between the chest trauma and the subsequent VF could not be ruled out and is in fact plausible despite the late onset.

The effectiveness and safety of spinal anaesthesia in the pyloromyotomy procedure.

BACKGROUND: Hypertrophic pyloric stenosis is a relatively common disorder of the gastrointestinal tract in infancy, causing projectile vomiting and metabolic abnormalities. Surgical management in the form of pyloromyotomy under general anaesthesia has been reported as safe for relieving the obstructed bowel. A number of studies have demonstrated the advantages of spinal anaesthesia over general anaesthesia in high risk infants undergoing minor infraumbilical surgery. The purpose of this study was to evaluate spinal anaesthesia as an alternative option to general anaesthesia in infants undergoing pyloromyotomy. METHODS: Twenty-five infants undergoing pyloromyotomy under spinal anaesthesia were studied. Haemodynamic and respiratory parameters were noted before performing the spinal block, 5 min after the spinal block, and every 10 min after performing the spinal block; for a total period of 30 min. The spinal block was performed using spinal isobaric bupivacaine 0.5%, 0.8 mg.kg-1. Blood pressure, heart rate, respiratory rate and oxygen saturation values were recorded. RESULTS: The sensory levels achieved ranged between T3-T5 thoracic segments within 6-8 min and were sufficient to perform surgery in 23 cases. There were no statistically significant differences in the oxygen saturation, systolic blood pressure and respiratory rate compared with before the spinal block and after 5, 10, 20 and 30 min. CONCLUSIONS: This study proposes that spinal anaesthesia is an alternative option to general anaesthesia in infants undergoing pyloromyotomy, and should be considered in infants undergoing pyloromyotomy.

Postdural puncture headache: an imaging-guided management protocol.

IMPLICATIONS: We propose an imaging-based algorithm for the management of headache caused by the inadvertent puncture of dura that occurs sporadically during epidural analgesia. Its implementation can identify those postdural puncture headache cases that cannot benefit from epidural blood patches, and their unnecessary application can consequently be avoided.

Flexible fiberoptic bronchoscopy through the laryngeal mask airway in a small, premature neonate.

The laryngeal mask airway (LMA) was introduced as a supraglottic device in anesthesia for routine use in the normal adult and pediatric population. Because the distal end of properly placed LMA faces the laryngeal inlet, this device can be used as a guide to flexible fiberoptic bronchoscopy (FFB) performance. In this clinical case, we present a small premature neonate with severe congenital biphasic stridor. FFB was performed successfully through the LMA while maintaining a patent airway during general anesthesia and permitting spontaneous respiration, as well as allowing assisted ventilation when necessary. An immediately subglottic intramural mass was revealed and tracheostomy was performed.

Bee stings of children: when to perform endotracheal intubation?

Hymenoptera stings account for more deaths in United States that any other envenomation. Oropharyngeal stings, although rare, may produce life-threatening airway obstruction by way of localized swelling. We present 4 cases of bee stings in children that necessitated tracheal intubation and mechanical ventilation. Two children had breathing difficulties at admission; the other 2 presented with minimal symptoms but were preventively intubated and mechanically ventilated. Orofacial bee sting victims should be given parenteral treatment with epinephrine, steroids, antihistamines, and inhalational bronchodilators even when they initially present with minimal symptoms, with general anaphylaxis management in large envenomations, as well as immediate endotracheal intubation and mechanical ventilation for at least 24 hours in patients with signs of airway compromise.
