Background: Neonatal cerebral imaging is a sensitive technique for evaluating brain injury in the neonatal period. When performing computed tomography or magnetic resonance imaging, sedation is needed to prevent motion artifacts. However, general anesthesia in neonates carries significant risks and requires a complex logistic approach that often limits the use of these modalities. The development of infant immobilizers now enables imaging without general anesthesia and significantly increases clinical and research investigational opportunities.

Objectives: To assess the efficacy of the infant immobilizer instead of general anesthesia for infants undergoing imaging.

Methods: The study group comprised all infants born over a 1 year period at Soroka University Medical Center who required imaging such as MRI, CT or bone scans. A MedVac Vacuum Splint infant immobilizer was used in all infants to prevent motion during imaging. The success rate of a single scan and the need for general anesthesia were assessed.  

Results: Forty infants were examined during 1 year. The studies included 15 CT scans, 25 MRIs and 1 bone scan. The infants’ gestational age at birth was 27–40 weeks and the examinations were performed at ages ranging from delivery to 6 months old. All imaging was successful and none of the infants required general anesthesia.

Conclusions: An infant immobilizer should be used for imaging of newborns. Since this method carries a low risk and has a high success rate, general anesthesia in newborns is justified only when this non-invasive procedure fails.
 

Historically physicians have had close relationships with the pharmaceutical or other medically related industry. This has come under close scrutiny by the public, with articles appearing in medical journals and the lay press. The reality is that physicians depend on industry to bring products to market as well as to assist in research and education, leaving physicians questioning what their relationship with industry should be. This review deals with this complex relationship, identifying ways that industry might affect decision making in the clinical context. We will highlight areas of potential concern in this relationship, identify attendant moral dilemmas, and provide some recommendations. Our intention in raising the consciousness of physicians and medical institutions to these potential areas of concern is to aid physicians in their efforts to provide the best medical care for patients and to practice with integrity.
