[Environmental monitoring and health monitoring for personnel exposed to inhalation anesthetics].

OBJECTIVES: The aim of this study is to verify the results of medical surveillance for personnel exposed to inhaled anaesthetics in operating rooms (300 exposed), and estimate the level of pollution in operating theatres of a university hospital. METHOD: Determination of the baseline and final value of the environmental anaesthetics by infrared photoacoustic spectroscopy; medical check-up and blood tests. RESULTS: During our observation we found in all rooms (new rooms and older rooms) values of nitrous oxide and isoflurane acceptable, all the anaesthetic's concentration are below the limits proposed by C.M. number 5 of the 14/03/89. Personnel reported subjective symptoms especially anxiety, but no blood alteration related to exposure were found. CONCLUSIONS: Technical precautions as use of low flow system, replacement of nitrous oxide with air, careful check of anaesthetic machine, and behavioral rules have decreased the emission of anaesthetics in the environment. Blood tests are found are not a valid index of possible damage caused by exposure. A large percentage of anaesthesiologists are found to have anxiety.

Anaphylaxis. What is monitored to make a diagnosis? How is therapy monitored?

Anaphylaxis is one of the most life-threatening emergencies that can occur in the perioperative period. Multiple agents can be responsible, and nonallergic reactions can mimic anaphylaxis. Developing a therapeutic plan for the acute therapy of anaphylaxis is important. Prompt recognition with appropriate and aggressive therapy can help avoid a disastrous outcome.

[Value of long-term ECG monitoring in the diagnosis of coronary disease--comparison of 8-hour ECG monitoring and double Master exercise test with a clinical coronary index].

The use of the long term Ecg (dynamic Ecg) in the diagnosis of coronary artery disease (CAD) has been investigated in 83 patients and its sensitivity compared with the double Master two step test. The average ECG registration time was 8 hours. The presence of CAD was assumed when the clinical index according to Cohn et al. revealed a pathological value. If a horizontal or downsloping ST-segment depression of greater than or equal to 0,5 mm was chosen for the diagnosis of CAD a sensitivity of 82% resp. 64% was found for the dynamic Ecg and the double Master two step test. The specificity of the dynamic Ecg however was with 77% slightly inferior compared with the Master-test. The superiority in sensitivity of the dynamic Ecg was also present when the diagnosis of CAD was based on a ST-segment depression of greater than or equal to 1,0 mm. We believe that the dynamic Ecg can provide besides arrhythmia detection valuable information in the diagnosis of CAD and careful interpretation of the ST-segment should therefore be undertaken. The number of false positive results in the diagnosis of CAD was not influenced by the women included in the study.
