[An ambulance manned by physicians--a different model].

An arrangement is described in which the general practitioners on duty participate in the ambulance service and the prehospital treatment of acutely ill patients. This arrangement has been followed prospectively for one year and was utilized in 141 cases. Approximately 40% of the cases involved cardiac patients and the remainder consisted of a varied assortment of other diagnoses. Attempts were made to resuscitate 11 patients with cardiac arrest and two of these could be discharged alive from hospital after admission. It is concluded that this arrangement is feasable as a means of improving the prehospital treatment of acutely ill patients but that it should be supplemented by increased efforts in training the population in resuscitation. In addition, it is concluded that the function of the alarm central was not optimal as half of the alarms came via the doctor on duty instead.

[A non-immobilizing regimen following meniscal suturing].

Vertical lesions in the peripheral third of the meniscus were sutured in 13 patients. The patients were treated with restricted activity postoperatively instead of immobilization. The patients were kept in bed until they could lift the leg with extended knee, which they were allowed up with careful support (and support with crutches) until the sutures were removed on the loth day. After removal of the sutures, patients were permitted to bear weight with the knee extended until limited by pain and were permitted unlimited flexion of the knee. From the 21st day, rehabilitation with weight-bearing with the flexed knee was permitted until they could be discharged with normal mobility and quadriceps power after an average of 6.4 weeks. Re-rupture was demonstrated in one patient. At the time of examination after a period of observation of 25.5 months, the patients had an average score of 78 points on Lysholm's functional scale from 0-100. These results are apparently similar to the results obtained following immobilizating regimens. The authors therefore conclude that it is ethically justifiable to carry out an extensive comparative investigation of the results after immobilizing and nonimmobilizating regimens, respectively, following suture of menisci. An investigation of this type appears to be necessary.

[A new cause of accidents resulting from the use of air-powered tools].

Air-powered tools are employed increasingly frequently in industry and involve new possibilities for occupational accidents. A new mechanism of trauma is described where the cause is failure of the snap connection between the tool and the air pipeline. The pipeline and the connection are hurled away from the tool with great force and can hit persons in the vicinity. During the period 1.1.1984 to 31.12.1986, 33 accidents of this type were registered with the workers' supervision authorities. 63% of these consisted to trauma to the neck, head and eyes. As prophylaxis, the present authors suggest a safety chain between the tool and the pipeline and a valve which interrupts the air supply when the pressure in the system falls.

[Ride-on rotary motor mowers--a new mechanism of injury. Home accidents].

A hand injury caused by a ridding-on rotary motor mower is described. The injury was caused by a piece of wire caught by the rotar of the machine which projected and rotated from under the safety guard. This mechanism of injury is possible on account of the relatively large dimensions of the riding-on rotory motor mower. The user had climbed down from the machine to remove objects lying close to the motor mower and was hit on the dorsum of the left hand. He sustained severe traumatic lesions of the first and third fingers and traumatic amputation of the second finger corresponding to the distal phalynx. The authors suggest that a "dead man's grib" which acts via weight bearing on the driver's seat of the machine should be made legally compulsory in Denmark when the new safety measures for rotory motor mowers are drawn up.

Sample loss during measurement of airborne antineoplastic agents.

Handling, preparation and administration of antineoplastic drugs are suspected health hazards for hospital and clinic personnel. Measurement of personal and area exposures to such materials in air is difficult because the average concentration is often close to the analytical detection limit. For this reason, and because of the random nature of drug spills and releases, the sampling method of choice typically extends over a 40-hour workweek. In this study a method for monitoring two airborne antineoplastic drugs, fluorouracil and methotrexate, was tested for possible loss of the drug from filters during air sampling. Glass-fiber filters (37 mm) were spiked with known amounts of drug and subjected to the same airflow conditions as are used in workplace sampling. Filter extracts were analyzed using high performance liquid chromatography (HPLC). Losses during storage up to a month were less than 5% for both drugs. Losses during airflow were directly proportional to cumulative air volume, 2% of the amount on the spiked filter/m3 air for fluorouracil and 6%/m3 for methotrexate. Losses during actual collection will be less and ordinarily are not expected to constitute a major hindrance to extended sampling in occupational settings.
