Management of massive haemoptysis with the rigid bronchoscope and cold saline lavage.

Twelve successive patients with massive haemoptysis were treated by emergency rigid bronchoscopy and lavage of the bleeding lung with cold saline. All patients stopped bleeding during the procedure and all blood and clot was evacuated from the accessible airways. The bleeding source was localised to a lobe in seven cases, and lateralised in the remaining five patients. Five patients had a second haemorrhage during that hospital stay and cold saline lavage again terminated it. Further therapy, either surgical or medical was based on information obtained during the respite from haemorrhage achieved with this technique. There was no hospital mortality in the series.

A clinical evaluation of cricothyroidotomy.

Cricothyroidotomies were performed upon 147 patients at the New York University Medical Center and Booth Memorial Center from March 1976 through February 1978. Cricothyroidotomy was demonstrated to be a rapid and technically simple and precise procedure. The incidence of complications was 8.6 per cent. Catastrophic complications occurred in two patients who had severe laryngeal stenosis. Cricothyroidotomy was performed following prolonged endotracheal intubation in these two patients who had airway obstruction immediately following endotracheal extubation. In both patients, there was a glottic and subglottic component to the laryngeal stenosis suggesting that endotracheal intubation as well cricothyroidotomy played a critical part in the development of laryngeal stenosis. In view of these observations, we believe that cricothyroidotomy is useful, particularly in emergency situations and in patients with median sternotomy incisions but is contraindicated in patients having endotracheal intubation of more than seven days' duration or in patients having airway obstruction develop following removal of an endotracheal tube except as a temporary lifesaving procedure.

Adenoid cystic carcinoma (cylindroma) and mucoepidermoid carcinoma of the bronchus. Factors affecting survival.

A review was made of the presentation, treatment, and follow-up of 20 patients with adenoid cystic carcinoma and 12 patients with mucoepidermoid carcinoma of the bronchus who were seen at the Mayo Clinic during the 50 year period 1927 through 1977. Three forms of therapy were employed: complete surgical resection, radiation therapy alone, and radiation therapy after endoscopic removal of tumor tissue. Superior results were obtained in the group with adenoid cystic carcinoma, when complete resection was possible. Significant survival and palliation of sepsis was achieved with subtotal resection. The mucoepidermoid carcinomas in this series were classified on the basis of histologic differentiation. Mucoepidermoid carcinoma of Grade 1 was managed by conservative pulmonary resection. Mucoepidermoid carcinoma of Grades 2 and 3 showed a greater propensity for malignancy. Widespread dissemination caused death with unresectable high-grade mucoepidermoid carcinomas of Grades 2 and 3.
