Lung and heart-lung transplantation: the state of the art.

Lung and heart-lung transplantation is one of the most rapidly evolving transplantation fields. Survival has been improving with better patient selection, better graft preservation, and better immunosuppression. This paper outlines criteria for patient selection, reviews the surgical options involving lung transplantation, and discusses factors influencing morbidity and survival in these patients. The Cleveland Clinic Foundation experience with these procedures is presented. Lung and heart-lung transplantation has emerged from the experimental realm to the therapeutic, and can now be offered as an effective treatment option to many patients with previously fatal heart and lung disorders.

Bullectomies for bullous sarcoidosis.

A 36-year-old woman presented with respiratory insufficiency due to cystic sarcoidosis. She had been previously treated with multiple courses of prednisone without improvement. Enlarging blebs involving both lower lobes impaired the function of the relatively spared upper lobes. Bilateral lower lobectomies were performed in one step via median sternotomy without complications, with prompt subjective and objective improvement of her respiratory status. One-stage bilateral upper-lobe bullectomy for bullous emphysema has been previously reported, but to our knowledge this is the first performance of one-stage bilateral lower-lobe bullectomies for cystic sarcoidosis. The immediate benefits were evident; long-term results will depend on the course of the underlying disease.

Lung transplantation: the Cleveland Clinic experience.

BACKGROUND: Lung transplantation has been steadily developing as a therapeutic option for end-stage lung disease. METHODS: Retrospective analysis of all 26 patients who underwent lung transplantation at the Cleveland Clinic Foundation between February 1990 and February 1992. RESULTS: Nineteen single-lung transplantations and seven bilateral lung transplantations were performed. The 1-year actuarial survival for all recipients was 65%. A trend was noted towards better survival in recipients with emphysema (100%) and poorer survival in those with pulmonary hypertension (37.5%). Fungal sepsis and reimplantation lung injury were the most common causes of death, and most deaths (8 of 9) occurred within the first 4 weeks. Of 119 pulmonary complications, 82% occurred in the first 3 months, with infection (39%) and acute rejection (29%) being the most common. Bacterial and fungal infections occurred mainly in the first month, and cytomegalovirus infections occurred mainly in the second and third months. The majority of survivors have shown improvement in functional status. CONCLUSIONS: The early perioperative and 1-month post-transplantation period appears critical to long-term survival. Even though the complications are numerous, they are usually manageable, and, in general, do not result in long-term morbidity.

Evaluation of two methods employed for cervical ripening.

The study evaluates breast stimulation and oxytocin infusion as methods for cervical ripening in patients where an obstetric indication for induction of labour exists. Forty patients with a Bishop score of 5 or 6 were randomly selected for either breast stimulation or oxytocin infusion. In a similar group of 20 cases, no method was employed. The Bishop score improved in 41.2% of cases where breast stimulation was used as compared to 75% where an oxytocin infusion was given. Three foetal deaths in the breast stimulation group brought the study to a stop after 17 cases. Cervical ripening with an oxytocin infusion drip appears to be a better method since infusion dosage can be precisely controlled making the technique more predictable and reliable. Though breast stimulation is effective in ripening the cervix, it may be used only in cases of intrauterine foetal death as it may otherwise adversely affect foetal outcome.
