[Anaphylactic shock following administration of an infusion solution containing fructose?].

A sixty-seven year old female patient who received post-operatively an i.v. infusion of Sterofundin I, suffered an anaphylactic shock with cyanosis, dyspnoea and progressive hypotension. Over a period of 90 min there were ECG changes similar to acute posterior myocardial infarction and arrhythmias (total AV-block with high compensative rate). This could be due to circulatory shock but more probably to a transitory coronary spasm. Clinical signs and symptoms exclude a hereditary fructose intolerance because of case history and blood results as well as complications described in the literature due to low dosage of fructose. An intracutaneous test confirmed a hypersensitivity of fructose-containing i.v. infusion.

Serial pulmonary function testing in patients with systemic lupus erythematosus.

Previous studies have documented the pulmonary function abnormalities associated with systemic lupus erythematosus (SLE). There are very few data, however, regarding the progression of such changes. To study this question, we evaluated the pulmonary function of a group of 25 patients with SLE from two to seven years after a set of pulmonary function tests had been performed as part of their overall initial assessment. Reductions in diffusing capacity, FVC, and total lung capacity did not change significantly for the group over the period of our study. The mean FEF25-75%, which was initially low, and the mean FEV1/FVC ratio, which was initially normal, both decreased significantly. The observed abnormalities in airway function were not related to smoking history. Other aspects of lupus activity, as measured by serum creatinine levels and clinical activity, did not appear related to progression of lung disease.

Differential lung blood flows in experimental unilateral emphysema: nonvalidity of perfusion scans.

As part of an evaluation of the effects of left lung transplantation in dogs with papain emphysema of the right lung, differential lung blood flows were estimated by in vivo scintiscan of 99Mc-macroaggregated albumin (99mTc-MAA) and, after sacrifice, by direct counting of isotopically labeled carbonized microspheres. In six dogs, percentage flow to the right lung was calculated at the following four times: before and after induction of papain emphysema and 2 and 6 weeks after left lung autotransplantation. After the induction of right lung emphysema, the right lung in four of six animals continued to receive more than 50 percent of the total pulmonary blood flow. No correlation could be established between right lung blood flow determined by carbonized microsphere distribution (true right lung blood flow) and the flow determined by anterior and posterior scintiscans (apparent right lung blood flow). This discrepancy was caused by gross distortion of the right, emphysematous lungs, which had herniated into the left hemithoraces. This herniation was demonstrated by coronal slices taken through the thoraces of two additional dogs with right lung emphysema that were given radiolabeled carbonized microspheres and 99Tc-MAA and frozen after sacrifice. These results indicate that external scintiscans for which the particulate distribution technique are used are invalid in circumstances of altered lung geometry.

Transplantation of the left lung into the right hemithorax to facilitate immediate reconstitution of bronchial artery flow.

Immediate bronchial artery reconstitution may be important in the prevention of bronchial anastomotic problems in lung transplantation. To facilitate this reconstitution in circumstances requiring allograft replacement of the right lung, we developed a method for transplanting the left lung together with its bronchial arterial supply into the right hemithorax. With this method, left lungs were allotransplanted into the right hemithorax of nine immunosuppressed dogs. Six recipients survived 1 to 4 weeks. Death resulted from pneumonia or rejection, and there were no bronchial anastomotic problems. Roentgenograms showed that the bronchial artery was patent and that the inverted transplanted left lungs could conform exactly to the thorax without space problems or radiographic abnormalities. Except for the unusual position of the large pulmonary arteries, angiographic patterns, function, and perfusion of the transplanted lungs were often normal and equivalent to those of the recipient's normal left lung. Thus it is possible to transplant a left lung into either hemithorax and immediately reconstitute its bronchial arterial circulation. Bronchial anastomotic problems may thereby be decreased.

Effective preservation and transportation of lung transplants.

To evaluate a system for preserving and transporting lungs before transplantation, we removed the left lungs of 37 dogs, flushed them with a hypertonic solution having an electrolyte composition resembling intracellular fluid, and immersed them at 4 degrees C. for 7 to 24 hours. Some lungs were maintained at exactly 4 degrees C. during transport by means of a mixture of solid and liquid l-hexadecene. The lungs were allografted into immunosuppressed dogs whose right pulmonary artery was immediately ligated. Twelve recipients (32 per cent) survived 5 days or more solely on the function of the preserved lung. Four survived 10, 19, 40, and 40 days with lungs that had been preserved for 7 to 21 hours. Survival of recipients of preserved lungs (5 +/- 2 days) was equivalent to that of 75 comparably immunosuppressed recipients of nonpreserved allografts (6 +/- 1 days). One group of 10 dogs receiving lungs flushed against outflow resistance survived 12 +/- 5 days. In recipients of preserved allografts, arterial oxygen tensions remained in the normal range up to 5 weeks after transplantation, and radiographic infiltrates in the transplant were no greater than those present in recipients of nonpreserved transplants. Thus lungs transported and preserved up to 21 hours can provide total pulmonary function after transplantation and can function at least as well as nonpreserved transplants. The effectiveness and simplicity of this method are such that it might be considered for use in man.
