The most appropriate airway device for use in EMS systems staffed by basic skilled EMTs with (EMT-Ds) or without (EMT-Bs) defibrillation capabilities is still a matter of debate. The purpose of this study was to assess the feasibility, safety and effectiveness of the Esophageal Tracheal Combitube (ETC) when used by EMT-Ds in cardiorespiratory arrest patients of all etiologies. The EMTs had automatic external defibrillator (AED) training but no prior advanced airway technique skills. ⋯ Immediate complications encountered, but not necessarily related to the use of the ETC, were; subcutaneous emphysema (18), tension pneumothorax (5), blood in the oropharynx (15), and swelling of the pharynx (three). An autopsy was done in 133 patients; no esophageal lesions or significant injury to the airway structures were observed. Our results suggest that EMT-Ds can use the ETC for control of the airway and ventilation in cardiorespiratory arrest patients safely and effectively.

Advances in diagnosis, techniques, therapeutic interventions, organisation of perinatal care, and socio-economic factors have all contributed to the survival after resuscitation and intensive care of neonates with extremely low birth weight and gestational age. While morbidity during the first years of life in those infants does not increase, at school age multiple dysfunctions may become apparent. What are the limits of intensive care for the newborn? Is it right to use extreme technical and economic measures for neonates with a borderline chance of survival? What is justifiable for the neonate, the family, the society and how does legislation interfere in a decision process which involves starting, stopping or continuing intensive care? A short historical overview for the care of the newborn is given, followed by the outcome after resuscitation and treatment of the very low birth weight infant. Published management strategies and recommendations are discussed.

Review Case Reports
Lung cancer presenting as cardiac tamponade associated with transmural myocardial ischaemia.
Cardiac tamponade due to carcinomatous pericarditis is a life-threatening complication of malignancy and is uncommon as its initial manifestation [Chest 88 (1985) 70; Cancer 45 (1980) 1697; J Am Med Assoc 257 (1987) 1088]. A case of lung cancer presenting with cardiac tamponade associated with transient ST-segment elevation and life-threatening arrhythmias is presented. To our knowledge, this is the first reported case of transmural myocardial ischaemia related to malignancy.

Randomized Controlled Trial Clinical Trial
Mild hypothermia induced by a helmet device: a clinical feasibility study.
To test the feasibility and the speed of a helmet device to achieve the target temperature of 34 degrees C in unconscious after out of hospital cardiac arrest (CA). ⋯ Mild hypothermia induced by a helmet device was feasible, easy to perform, inexpensive and effective, with no increase in complications.

Comparative Study
Assessment of the use of the laryngeal tube for cardiopulmonary resuscitation in a manikin.
During 60 3-min CPR sequences, the face mask, laryngeal tube and tracheal tube were compared using an Ambu Megacode Trainer. Ten 3-min sequences each were performed for both a combination of the face mask and laryngeal tube with a bag-valve device (compression-ventilation ratio 5:1). With continuous chest compressions, ten 3-min CPR sequences each were performed for a combination of the laryngeal tube and tracheal tube with a bag-valve device and ten 3-min CPR sequences each for a combination of the laryngeal tube and tracheal tube with an automatic transport ventilator. ⋯ Ventilation with the laryngeal tube was significantly better than with the face mask and comparable to the tracheal tube during ventilation with the bag-valve device and with the automatic transport ventilator. Chest compressions caused a significant decrease in tidal volumes during ventilation with the automatic transport ventilator. The findings of this study support the idea of the laryngeal tube as a new adjunct for emergency airway management, but will have to be verified during clinical practice.
