[Fastrach laryngeal mask, sevoflurane and remifentanil: an anesthetic alternative for the myasthenic patient].
A 46-year-old myasthenic man diagnosed two months earlier and experiencing nocturnal dyspnea was scheduled for transsternal thymectomy. The patient was premedicated with midazolam in the operating room. Anesthetic induction and maintenance were with inhaled sevoflurane and an intravenous infusion of remifentanil, with no need for neuromuscular relaxants. Airway management was achieved by inserting a Fastrach laryngeal mask (LM-Fastrach), through which an endotracheal tube could be inserted easily. The tube was withdrawn through the mask at the end of surgery and the mask was removed in the operating room 6 minutes later. Anesthesia in patients with myasthenia gravis is one of the greatest challenges in clinical anesthesiology. The interest of this case lies mainly in that the anesthetic technique chosen allows neuromuscular relaxants to be avoided. Moreover, airway access through the Fastrach laryngeal mask is highly useful for transsternal thymectomy of the patient with myasthenia gravis, providing immobility and adequate hemodynamic stability during sternotomy as well as facilitating safe and rapid postanesthetic recovery.

[Approach to bronchopleural fistula in patients undergoing lung cancer surgery. A prospective study].
Twenty-four cases of bronchopleural fistula were found by fiberoptic bronchoscopy performed in 526 consecutive patients undergoing surgery for diagnosis or treatment of lung cancer between February 1990 and January 1997 in Hospital General Universitario in Valencia (Spain). In 327 of the patients lung resection was performed. Clinical symptoms included fever, purulent or bloodstained expectoration, chest pain, dyspnea and general unfitness, with 83.33% of the patients having pleural empyema. Treatment was based on pleural drainage and broad-spectrum antibiotic therapy, along with planning of the appropriate surgery technique to each patient. Surgery consisted in re-thoracotomy and bronchial closure in early detection cases without evidence of infection (< 48 h); thoracostomy (Clagett) and second stage myoplasty if confirmed pleural infection; thoracoplasty in cases of incomplete fistulas that were unresolved by pleural drainage. Biological glues were delivered by fiberoptic bronchoscope in one patient. The incidence of bronchopleural fistula was studied, as were associated factors and the results obtained by various surgical techniques.

[Comparative study of preemptive and postincisional lumbar epidural morphine in pulmonary resection. Preliminary report].
OBJECTIVES: To evaluate the efficacy and incidence of side effects of two types of lumbar epidural analgesia with morphine, preemptive or postincisional, combined with total intravenous anesthesia in chest surgery. PATIENTS AND METHODS: This double-blind prospective study enrolled 20 patients (ASA I-IV) undergoing lobectomy or pneumonectomy. Anesthetic induction and maintenance was provided with propofol, atracurium and alfentanil. Lumbar epidural analgesia (L2-L3) with morphine was provided for group A patients with 2 to 4 mg upon excision of tissue and for group B with 2 to 4 mg during anesthetic induction. The following variables were recorded: arterial blood gas concentrations, heart rate, SpO2, EtCO2, postanesthetic recovery, arterial gases, side effects and pain on a visual analogue scale. Top-up analgesia was provided by intravenous metamizole and/or epidural morphine. For statistical analysis we used ANOVA, chi-square tests and Student-Newman-Keuls tests. RESULTS: The need for propofol and alfentanil during anesthesia, and for morphine and metamizole after surgery were statistically greater in group A. Pain 18 hours after surgery was also greater in group A. No significant differences between groups for other variables was observed. CONCLUSIONS: Preemptive analgesia with lumbar epidural morphine in addition to the general anesthesia described here seems to provide higher-quality analgesia with few side effects, reducing the need for propofol and alfentanil during surgery and for postoperative morphine and metamizole.

Videothoracoscopy in the diagnosis and treatment of malignant pleural mesothelioma with associated pleural effusions.
Between 1985 and 1994 46 of 662 patients examined by thoracoscopy for secondary malignant pleural effusion were diagnosed to have diffuse malignant pleural mesothelioma. Mean patient age was 59 years, with a male: female ratio of 5:1. The right hemithorax was more frequently involved than the left (55% versus 45%). Pleural fluid cytology revealed malignancy in 61.5% of cases. All patients were treated thoracoscopically by talc pleurodesis. Mean patients survival was 9.4 months. Survival after one, two, and 5 years was 37.5%, 12.5%, and 5%, respectively. The characteristics of mesothelioma and pleural effusion evident in thoracoscopy and their diagnostic relevance are discussed. We suggest talc instillation as the sole therapeutic maneuver in evolutioned cases, since the literature and our own experience indicate that survival is not significantly prolonged by more aggressive surgical approaches.

[Videothoracoscopy in staging of lung cancer].
We present a review of 108 cases of lung cancer in patients who, for a variety of reasons outlined in this report, underwent video assisted thoracoscopy prior to staging. Overall results of the procedure were positive in 94%. We report the usefulness of this tool for identifying adenopathic locations, for effecting biopsies of tumors that could not be typed by other means, for resecting peripheral nodules for screening purposes, and for making etiological diagnoses of accompanying pleural effusions. For diagnostic purposes, this procedure provides a better image than does conventional thoracoscopy, involves the participation of an endoscopy team and even calls for the presence of a pathologist. We consider video assisted thoracoscopy to be a highly effective tool for avoiding so-called pointless thoracotomies and for completing alternative treatments. Its cost effectiveness is indisputable, as are its low rates of morbidity and mortality.

[Pulmonary leiomyosarcoma].
We present the case of a young patient with leiomysarcoma of the lung that was at first diagnosed as a hydatid cyst. Pathological tissue analysis was needed for firm diagnosis. This rare tumor, of which fewer than 100 cases have been reported worldwide in the literature, needs to be considered as a differential diagnosis when lung cancer is suspected, given that leiomysarcoma has a better prognosis. Treatment is mainly surgical.

[Prognostic value of positive cytology found in pleural lavage of patients with cancer of the lung. Prospective study].
Pulmonary neoplasms can deposit malignant cells in the pleural cavity by a variety of mechanisms, depending not only on histological type but also on clinical stage. We investigated the effect on survival rate of a finding of malignant cells in pleural lavage. We also investigated the effect of the presence of pleural metastasis on postoperative course of disease. Two hundred surgical patients at Hospital General Universitario in Valencia between 1 February 1990 and 30 March 1993 were studied. Two groups were formed. Group one: 150 patients with lung cancer, none of whom had had pleural effusion prior to suffering transthoracic puncture during the preoperative study. Patients treated with parallel chemotherapy or radiotherapy were excluded in order to circumvent false positives. Group two: 50 patients with no tumors who underwent thoracotomy for reasons other than lung cancer. All patients underwent pleural lavage with saline before and after lung exeresis. We found 26.6% (40/150) positive cytologies in the pre-and postoperative lavages in the first group. None were found in the control group.
