Enzyme exposure, smoking and lung function in employees in the detergent industry over 20 years. Medical Subcommittee of the UK Soap and Detergent Industry Association.

This study was undertaken to examine the long term relationship between lung function, smoking and exposure to enzymes in the detergent industry. A total of 731 male workers from five locations in the United Kingdom were subject to respiratory health surveillance including lung function testing over a period of 4-20 years. Exposure groups were defined by job history. Significantly different rates of fall in FEV1 and FVC with time were found by geographical location and by smoking habit, but there were no consistent trends with enzyme exposure.

Current best practice for the health surveillance of enzyme workers in the soap and detergent industry.

This study defines current best practice for the health surveillance of workers who are potentially exposed to enzymes in the manufacture of enzymatic detergent products. It is recommended that health surveillance is performed 6-monthly for the first 2 years and annually thereafter. The health surveillance programme should include a respiratory questionnaire to detect symptoms, assessment of lung function to detect pre-symptomatic changes and an immunological test to detect specific immunoglobulin E (IgE) to enzymes. The International Union Against Tuberculosis and Lung Disease respiratory questionnaire should be used since it has been validated extensively for detecting asthma. Operators should observe the American Thoracic Society performance criteria for spirometers and standardized procedures for conducting spirometry. Since current airborne monitoring techniques for enzymes do not detect short-duration peak exposures, the incidence of employee sensitizations remains the most reliable measure of the integrity of environmental control. The Pepys skin prick test has been validated as a sensitive, specific and practical test for detecting specific IgE to many inhalant allergens including enzymes. For newly sensitized workers, a multi-cause investigation should be conducted to identify potential sources of exposure. Group results of immunological test results assist in the evaluation of workplace control measures, and should be used to monitor the effectiveness of hygiene and engineering programmes and to help prioritize areas for improvement. Positive responses to a questionnaire or abnormal spirometry should be assessed further. Occupational asthma should be excluded in any case of adult-onset asthma that starts or deteriorates during working life. This is particularly important because an accurate diagnosis of occupational asthma with early avoidance of exposure to its cause can result in remission of symptoms and restoration of lung function.

Randomized, controlled clinical trial of point-of-care limited ultrasonography assistance of central venous cannulation: the Third Sonography Outcomes Assessment Program (SOAP-3) Trial.

CONTEXT: A 2001 Agency for Healthcare Research and Quality Evidence Report on patient safety addressed point-of-care limited ultrasonography guidance for central venous cannulation and strongly recommended real-time, dynamic guidance for all central cannulas. However, on the basis of one limited study, the report dismissed static assistance, a "quick look" with ultrasound to confirm vein location before preparing the sterile field, as unhelpful. OBJECTIVE: The objective of this trial was to compare the overall success rate of central cannula placement with use of dynamic ultrasound (D), static ultrasound (S), and anatomical landmarks (LM). DESIGN AND SETTING: A concealed, randomized, controlled, clinical trial conducted from September 2003 to February 2004 in a U.S. urban teaching hospital. PATIENTS: Two-hundred one patients undergoing internal jugular vein central venous cannulation. INTERVENTIONS: Patients were randomly assigned to three groups: 60 to D, 72 to S, and 69 to LM. An iLook25 SonoSite was used for all imaging. MEASUREMENTS AND MAIN RESULTS: Cannulation success, first-attempt success, and number of attempts were noted. Other measures were vein size and clarity of LM. Results, controlled for pretest difficulty assessment, are stated as odds improvement (95% confidence interval) over LM for D and S. D had an odds 53.5 (6.6-440) times higher for success than LM. S had an odds 3 (1.3-7) times higher for success than LM. The unadjusted success rates were 98%, 82%, and 64% for D, S, and LM. For first-attempt success, D had an odds 5.8 (2.7-13) times higher for first success than LM, and S had an odds 3.4 (1.6-7.2) times higher for first success than LM. The unadjusted first-attempt success rates were 62%, 50%, and 23% for D, S, and LM. CONCLUSIONS: Ultrasound assistance was superior to LM techniques. D outperformed S but may require more training and personnel. All central cannula placement should be conducted with ultrasound assistance. The 2001 Agency for Healthcare Research and Quality Evidence Report dismissing static assistance was incorrect.

Sepsis in European intensive care units: results of the SOAP study.

OBJECTIVE: To better define the incidence of sepsis and the characteristics of critically ill patients in European intensive care units. DESIGN: Cohort, multiple-center, observational study. SETTING: One hundred and ninety-eight intensive care units in 24 European countries. PATIENTS: All new adult admissions to a participating intensive care unit between May 1 and 15, 2002. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Demographic data, comorbid diseases, and clinical and laboratory data were collected prospectively. Patients were followed up until death, until hospital discharge, or for 60 days. Of 3,147 adult patients, with a median age of 64 yrs, 1,177 (37.4%) had sepsis; 777 (24.7%) of these patients had sepsis on admission. In patients with sepsis, the lung was the most common site of infection (68%), followed by the abdomen (22%). Cultures were positive in 60% of the patients with sepsis. The most common organisms were Staphylococcus aureus (30%, including 14% methicillin-resistant), Pseudomonas species (14%), and Escherichia coli (13%). Pseudomonas species was the only microorganism independently associated with increased mortality rates. Patients with sepsis had more severe organ dysfunction, longer intensive care unit and hospital lengths of stay, and higher mortality rate than patients without sepsis. In patients with sepsis, age, positive fluid balance, septic shock, cancer, and medical admission were the important prognostic variables for intensive care unit mortality. There was considerable variation between countries, with a strong correlation between the frequency of sepsis and the intensive care unit mortality rates in each of these countries. CONCLUSIONS: This large pan-European study documents the high frequency of sepsis in critically ill patients and shows a close relationship between the proportion of patients with sepsis and the intensive care unit mortality in the various countries. In addition to age, a positive fluid balance was among the strongest prognostic factors for death. Patients with intensive care unit acquired sepsis have a worse outcome despite similar severity scores on intensive care unit admission.

Does dopamine administration in shock influence outcome? Results of the Sepsis Occurrence in Acutely Ill Patients (SOAP) Study.

OBJECTIVE: The optimal adrenergic support in shock is controversial. We investigated whether dopamine administration influences the outcome from shock. DESIGN: Cohort, multiple-center, observational study. SETTING: One hundred and ninety-eight European intensive care units. PATIENTS: All adult patients admitted to a participating intensive care unit between May 1 and May 15, 2002. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were followed up until death, until hospital discharge, or for 60 days. Shock was defined as hemodynamic compromise necessitating the administration of vasopressor catecholamines. Of 3,147 patients, 1,058 (33.6%) had shock at any time; 462 (14.7%) had septic shock. The intensive care unit mortality rate for shock was 38.3% and 47.4% for septic shock. Of patients in shock, 375 (35.4%) received dopamine (dopamine group) and 683 (64.6%) never received dopamine. Age, gender, Simplified Acute Physiology Score II, and Sequential Organ Failure Assessment score were comparable between the two groups. The dopamine group had higher intensive care unit (42.9% vs. 35.7%, p=.02) and hospital (49.9% vs. 41.7%, p=.01) mortality rates. A Kaplan-Meier survival curve showed diminished 30 day-survival in the dopamine group (log rank=4.6, p=.032). In a multivariate analysis with intensive care unit outcome as the dependent factor, age, cancer, medical admissions, higher mean Sequential Organ Failure Assessment score, higher mean fluid balance, and dopamine administration were independent risk factors for intensive care unit mortality in patients with shock. CONCLUSIONS: This observational study suggests that dopamine administration may be associated with increased mortality rates in shock. There is a need for a prospective study comparing dopamine with other catecholamines in the management of circulatory shock.
