Spontaneous pneumothorax: is it under tension?

A diagnosis of tension pneumothorax is usually only considered within the context of trauma, incorrect chest drain insertion or positive pressure ventilation. Four patients are presented who developed spontaneous tension pneumothorax with no precipitating factors. In three of these instances, the diagnosis was only made radiologically and in every case the treating physician was unaware that a spontaneous tension pneumothorax could occur. Previously, emphasis has been placed on tracheal deviation in a tension pneumothorax. However, this is an inconsistent finding as one of the cases highlights. Patients may appear surprisingly clinically well until they decompensate. These cases are highlighted to raise awareness of this potentially life threatening condition.

Accident and emergency department led implementation of ketamine sedation in paediatric practice and parental response.

OBJECTIVE: To evaluate accident and emergency (A&E) department led practice of ketamine sedation for painful, short procedures in the paediatric population and to ascertain parental response. METHODS: Analysis of retrospective data for all children who received ketamine sedation over a 20 month period in a district general hospital. A data extraction form was used to record age, sex, dose, indication, side effects, and outcome. The parents were contacted by telephone afterwards and asked standardised questions about the child's treatment, their progress after discharge, and overall satisfaction with the treatment. RESULTS: Intramuscular ketamine was administered to 100 children under 12 years of age during the study period. The drug caused no adverse events pre-operatively or intraoperatively. The main early postoperative complication was vomiting (14%). Ninety three per cent of patients were discharged the same day. No reattendance or treatment attributable to ketamine related side effects were necessary. Over the 24 hours after discharge, vomiting occurred in 12% and ataxia in 15% of patients. Ninety nine per cent of parents were either very satisfied or satisfied with ketamine sedation and were willing for their child to receive it again, if required. CONCLUSION: This study, while confirming the known safety of ketamine sedation, established its suitability for "independent" use within A&E departments by suitably qualified staff.
