ABSTRACT
INTRODUCTION: The "target" of acupuncture is usually the muscle, but it occasionally approaches other anatomical structures such as the pleura, which may subsequently suffer damage. OBSERVATION: During a session of acupuncture, a 25-year-old woman had a malaise with shock and neurological disorders. The initial examinations revealed a bilateral pneumothorax associated with pericardial and peritoneal effusions. Symptomatic reanimation combining dopamine, left pleural draining and pericardial puncture led to rapid haemodynamic improvement. The etiological exploration, having eliminated an underlying pathology, concluded in the diagnosis of tamponade and bilateral pneumothorax following a session of acupuncture. COMMENTS: Our patient presented the association of two traumatic complications of acupuncture: cardiac tamponade due to haemopericardium and bilateral pneumothorax. Although these complications are rare, they must be known.

OBJECTIVES: To analyse the various methods for carbon dioxide absorption in anaesthesia, the available absorbents and their modes of use. DATA SOURCES: We searched the Medline and Internet databases for papers using the key words: carbon dioxide absorption, soda-lime, zeolite. We also had correspondence and contacts with soda lime manufacturers. STUDY SELECTION: All types of articles containing data on CO2 absorption. DATA EXTRACTION: The articles were analysed for the benefits and adverse effects of the various absorbents. DATA SYNTHESIS: Carbon dioxide absorption enables the use of low flow anaesthesia, and a decreased consumption of medical gases and halogenated anaesthetics, as well as reduced pollution. Chemical absorbents (soda-lime and barium hydroxide lime (Baralyme) may produce toxic compounds: carbon monoxide with all halogenated anaesthetics and compound A with sevoflurane. Simple measures against desiccation of the lime prevent carbon monoxide production. The toxicity of compound A, shown in the rat, has not been proven in clinical anaesthesia. Recent improvements in manufacture processes have decreased the powdering of lime. Moreover, filters inserted between the anaesthesia circuit and the patient abolish the risk for powder inhalation.

Severe head injury (Glasgow Coma Score less than or equal to 7) is associated with high mortality and morbidity which can be improved by early energetic therapy. Such patients must be picked up by prehospital/EMS service with three aims: controlling ventilation, controlling haemodynamics, avoiding any increased intracranial pressure. After initial neurological assessment, management involves endotracheal intubation, mechanical ventilation following benzodiazepine sedation, early compensation of hypovolemia avoiding any overloading, analgesia for painful injuries; according to the clinical status other pharmacological agents can be used. At admission to emergency unit, intensive care must be continued while X-rays and CT-scan are achieved. Imperative indications of transport to neuro-intensive care unit are discussed for hospitals without a neuro-surgeon.

Rapid fluid infusion remains the cornerstone for therapy of hypovolaemic shock. The principal limitations of flow rate are governed by the four variables of Poiseuille's law: tube internal diameter and length, viscosity of the fluid passing through the tube, and the pressure gradient between the two ends of the tube. Conventional transfusion systems, with wide bore tubing (up to 5.0 mm internal diameter), large bore cannulas (8.5 French introducer catheters), high pressure (up to 300 mmHg) and diluted blood, can result in a maximum flow rate of about 1,000 ml.min-1 (for crystalloid solutions). Specific apparatus for rapid infusion can increase this to 1,500 ml.min-1 (Rapid Infusion System, Haemonetics). Dry-heat warming devices and microfiltration, to remove microaggregates and prevent non haemolytic febrile transfusion reactions, seem necessary when carrying out rapid transfusions. However, the use of microaggregate filters could be avoided by the routine production of leukocyte-poor red blood cell concentrates.
