Reduction of noise levels in intensive care units for infants: evaluation of an intervention program.
OBJECTIVE: To investigate whether educational information for nurses concerning causes of noise would decrease noise levels in an intensive care unit for term newborns and infants. DESIGN: Pretest and posttest. SETTING: Children's surgical ward in a university hospital in southern Sweden. SUBJECTS: Fifty-two nurses in the surgical ward. OUTCOME MEASURES: Noise levels. INTERVENTION: An educational program consisting of a presentation of a videotape, presentation of the decibel values for various care activities, and a discussion of the problem. RESULTS: Statistical analysis with a paired two-tailed t test showed significant differences to exist between measurements in a cot and an incubator before the intervention (p = 0.0001), and between cot measurements before and after the intervention program (p = 0.0007). CONCLUSIONS: The results of this study show that through simple methods and without additional costs, and by making the staff aware of the problem, noise levels can be lowered considerably.

Reduction of radiation dose in radiologic examination of patients with scoliosis.
In an attempt to reduce the radiation dose during the examination of scoliotic patients, several screen-film combinations have been compared with a conventional system used at present. Kodak's Lanex Regular screen with Kodak Ortho H film enables the dose to be reduced eight times without significant deterioration of the image quality. The dose to the mammary glands can be reduced further by a factor of five if posterior--anterior instead of anterior--posterior projection is used.

Care of infants after major surgery: observation of behavior and analgesic administration.
To examine pain management in infants after surgery, 12 infants were observed and audiovisually recorded for 24 hours postoperatively following major surgery. Analgesic administration, sleep-awake states, facial expression-vocalization, and care routines were monitored. A clinical pain scoring system (Attia, Amiel-Tison, Mayer, Shnider, & Barrier, 1987) was used to analyze the video tapes. Only 5 infants showed occasional episodes of quiet sleep and were awake for 50% of the observed episodes. Moaning-crying was observed in 56% of the episodes for 4 infants and in 29% of the episodes for 6 infants. Analysis using the pain scoring system showed 36% of the episodes to have scores below 14 (M = 7.7). Results indicated that pain management was inconsistent, care routines need to be changed and better coordinated, and environmental issues must be addressed.
