Apnea testing in brain death.

A standardized protocol was followed in 33 apneic oxygenation tests on 20 patients suspected of being brain dead. Spontaneous respiratory movements developed in just one patient; this patient was the only one who did not show electrocerebral silence on electroencephalography. Significant hypoxemia, hypotension, or cardiac arrhythmias were not encountered despite lung disease in 14 of our 20 patients. The apnea test protocol employed proved to be safe and sensitive. With a starting partial arterial carbon dioxide pressure greater than or equal to 36 mm Hg and a disconnection time from the ventilator of ten minutes in a normothermic patient (greater than or equal to 36.1 degrees C [greater than or equal to 97 degrees F]), the pressure threshold of 60 mm Hg should be reached in all patients.

[Complications after harvesting of autologous bone from the ventral and dorsal iliac crest - a prospective, controlled study].

INTRODUCTION: In a prospective, controlled study, donor site morbidity after bone graft harvesting from the anterior and posterior iliac crest was documented. METHODS: In 113 patients, monocortical to tricortical bone grafts were taken from the anterior (n = 73) or dorsal (n = 40) iliac crest. Bone graft size (0.4 - 43 cm 3, median 9.7 cm 3), Operation time (12 - 65 minutes, median 28 minutes), and postoperative donor site were documented. RESULTS: Donor site morbidity was higher after harvesting from the ventral than from the dorsal iliac crest: total morbidity 48 vs. 32.5 %, large haematomas 9.6 vs. 7.5 %, moderate haematomas 34.3 vs. 15 %, wound dehiscence 2.7 vs. 0 %. One revision operation was necessary because of a large haematoma at the ventral crest. After harvesting from the ventral iliac crest, there was one fracture ofthe iliac wing and one avulsion fracture of the iliac crest. There were no infections, no injuries of arteries or of the lateral femoral cutaneous nerve and no hemiation. After harvesting from the dorsal iliac crest, there were no major complications. CONCLUSION: Bone graft harvesting from the posterior iliac crest should be preferred over harvesting from the anterior iliac crest beeause of the substantially reduced donor site morbidity. Harvesting from the ventral iliac crest should have a clear indication, synthetic bone substitutes should be taken into consideration.
