We present a case in which a patient with normal pulmonary reserve experienced orthopnea and hypoxia secondary to unilateral diaphragmatic paralysis following right scalenectomy. This operation was performed in an attempt to relieve neurovascular compromise at the thoracic outlet. To our knowledge, this association has not been previously described in the literature.
One promising approach to strengthening theory-research and theory-practice linkages is to place greater emphasis on developing and using theories of the middle range to underpin nursing research and practice. In this article, a postpositivistic definition of middle-range theory is advanced, an argument is made for shifting nursing's theory development activities from discipline-defining grand theories to middle-range theories, and a collaborative and incremental approach to middle-range theory development is described and illustrated. A sustained substantive example is provided by the beginning development of a theory of unpleasant symptoms.
