Tracheostomy ventilation versus diaphragmatic pacemaker ventilation in high spinal cord injury.

We have made a retrospective comparative study of patients with spinal cord injury, nine with a diaphragmatic pacemaker and 13 with mechanical ventilation. Clinical outcome, cost and subjective satisfaction with both modalities have been evaluated. The functional status was the same with both types of treatment. Proper management of an electric wheelchair and optimal phonation were attained, respectively, in 100% and 89% of pacers and in 77% and 77% of mechanically ventilated. The rate of hospital discharge and satisfaction with the treatment were significantly better for pacers. The time devoted to ventilatory assistance and cost were also more favourable in this group.

[Crohn disease in 3 siblings].

Three siblings without a known familiar history of chronic inflammatory disease of the intestine suffered Crohn's disease. They were the 3rd, 4th and 8th siblings of a family of 8 siblings. The onset of the disease and its course were similar in all three patients. Considering the form of familial presentation and the possible influence of environmental factors in this type of patients, a review is made of the influence of these factors in accordance with the clinical patients' evolution.

Continuous respiratory support in quadriplegic children by bilateral phrenic nerve stimulation.

Three children, aged 6-10 years, in whom cervical cord injury at the C1-C2 level resulted in apnoea had bilateral implantation of diaphragm pacemakers. With periods of gradual conditioning of the diaphragm muscle to low frequency stimulation and slow respiratory rates they adapted to continuous ventilatory support by simultaneous stimulation of both hemidiaphragms without evidence of fatigue, so far for periods of 23-47 months.

Permanent artificial respiration by diaphragm pacemaker in tetraplegic children.

This is a study of two children, aged respectively 10 and 6 years, who sustained a spinal cord injury at the C1 C2, causing apnoea. After the bilateral implantation of diaphragm pacemakers and periods of conditioning, they were able to adapt to continuous and simultaneous full-time ventilatory support of both diaphragms without any sign of fatigue, for more than 24 and 11 months, respectively.

Bioelectrical tissue resistance during various methods of myocardial preservation.

Twenty-one mongrel dogs underwent cardiopulmonary bypass (CPB) and ischemic cardiac arrest for 60 minutes. The bioelectrical tissue impedance, water content, and ultrastructure of the myocardium were studied and correlated with various types of myocardial protection applied. The animals were divided into three groups according to the myocardial protection applied: Group 1, moderate general hypothermia; Group 2, moderate general and local hypothermia; Group 3, moderate general hypothermia and crystalloid cardioplegia. The hearts from 3 normal dogs served as controls. After 35 minutes of ischemic arrest, the difference in bioelectrical impedance of the myocardium of the left ventricle between Groups 1 and 2 was highly significant (p less than 0.001); in Groups 2 and 3, a significant difference was observed after 50 minutes. The heart water content in all three groups increased over that found in the hearts of the control animals, but there was no significant difference between Groups 2 and 3. There was evidence by ultramicroscopic study of ischemic damage to the myocardium in all of the experimental groups. Damage was less evident in Groups 2 and 3. We conclude that measurement of myocardial bioelectrical tissue resistance is a sensitive indicator of myocardial damage due to ischemia and may be useful clinically in determining the need for and type of cardiac resuscitation, particularly following CPB.

Homograft of the small intestine. Metabolic and functional changes causing irreversible shock.

Homotransplantation of the small intestine is subject to high mortality in the first 48 hours after operation. We analyzed various causes of death, underlining the importance of postoperative shock, then developed an experiment in dogs with the object of improving the survival. We applied various therapeutic measures in order to reduce the factors which participate in the evolution of chronic, hypovolemic and toxic shock. We attempted to: (1) reduce the consecutive alterations to ischemia of the homotransplant during the non-perfusion period; (2) reduce the deleterious effect of retained fecal matter; (3) reduce the metabolic acidosis secondary to clamping of the great vessels; (4) acknowledge, analyze and correct alterations in fluid and electrolyte balances; (5) correct the blood volume; and (6) prevent infection. With these measures we have increased the survival rate.
