ABSTRACT
BACKGROUND: The mortality rate in patients with severe community-acquired pneumonia (SCAP) is high. We investigated the 5-year mortality rate and causes of death in a patient population treated for SCAP in our intensive care unit (ICU), and compared the mortality rate in patients with or without chronic obstructive pulmonary disease (COPD) as comorbidity. METHODS: This retrospective study, which covers a period of 10 years, included patients aged > 18 years admitted to our ICU with SCAP as primary diagnosis and in need of mechanical ventilation for more than 24 h. Data were collected from the ICU internal database and the patients' medical records. The times of death were collected from the Norwegian National Registry, and the causes of death from the Norwegian Cause of Death Registry. RESULTS: Hundred and seventy three patients were included in the study. The 5-year mortality rate for the total study population was 57.2%. There were no significant differences in the mortality rate between the group with COPD and the group without COPD (61.2% vs. 54.7%, P = 0.43). There was a wide range of comorbidities. The most common were COPD, myocardial infarction and diabetes mellitus. The two main causes of death after discharge were COPD (17 deaths) and cardiovascular diseases (seven deaths). CONCLUSIONS: The 5-year mortality rate of the study population was high (57.2%). COPD did not seem to be a risk factor for mortality compared to non-COPD patients. The most common causes of death after discharge were COPD and cardiovascular diseases.

INTRODUCTION: A case is presented in which a 43-year-old man suffering from a severe asthma attack, had ventilatory arrest during a hoisting procedure. Based on this experience, the influence of three hoisting techniques on lung function was tested. METHODS: The ventilatory capacity of 12 healthy volunteers was tested during three commonly used hoisting techniques: 1) single sling; 2) double sling; or 3) strapped to a stretcher. RESULTS: The vital capacity (VC) and the one-second, forced expiratory volume (FEV1) were reduced significantly during all hoisting techniques compared to the standing position. The reduction was significantly more pronounced on a stretcher than in either sling position. There were no differences in the FEV1 to VC ratio between the positions. CONCLUSION: The small reduction in ventilatory capacity during hoisting procedures is tolerated easily by healthy individuals, but should be taken into account when planning such procedures on patients with severe pulmonary disease.

Two hundred and eight healthy children who were to undergo minor elective surgery during halothane, nitrous oxide, oxygen anaesthesia were studied in a double blind investigation to evaluate the sedative and anticholinergic effects of two rectal premedications. Group I received diazepam 0.75 mg/kg rectally; Group II received a mixture of diazepam 0.5 mg/kg, morphine 0.15 mg/kg and hyoscine 0.01 mg/kg rectally. No significant difference was found between the two groups in sedative or anticholinergic effects during induction of anaesthesia or in the postoperative period. No adverse effects were seen.
