A need was identified for a fixed-format self-complete questionnaire for measuring health in chronic airflow limitation. A 76-item questionnaire was developed, the St. George's Respiratory Questionnaire (SGRQ). Three component scores were calculated: symptoms, activity, and impacts (on daily life), and a total score. Three studies were performed. (1) Repeatability was tested over 2 wk in 40 stable asthmatic patients and 20 patients with stable COPD. The coefficient of variation for the SGRQ total score was 19%. (2) SGRQ scores were compared with spirometry, 6-min walking distance (6-MWD), MRC respiratory symptoms questionnaire, anxiety, depression, and general health measured using the Sickness Impact Profile score. A total of 141 patients were studied, mean age 63 yr (range 31 to 75) and prebronchodilator FEV1, 47% (range 11 to 114%). SGRQ scores correlated with appropriate comparison measures. For example, symptom score versus frequency of wheeze, r2 = 0.32, p less than 0.0001; activity versus 6-MWD, r2 = 0.50, p less than 0.0001; impact versus anxiety, r2 = 0.38, p less than 0.0001. Multivariate analysis demonstrated that SGRQ scores summed a number of areas of disease activity. (3) Changes in SGRQ scores and other measures were studied over 1 yr in 133 patients. Significant correlations were found between changes in SGRQ scores and the comparison measures (minimum r2 greater than 0.05, p less than 0.01). Multivariate analysis showed that change in total SGRQ score summed changes in a number of aspects of disease activity. We conclude that the SGRQ is a valid measure of impaired health in diseases of chronic airflow limitation that is repeatable and sensitive.

Benzodiazepine drugs have been shown to suppress respiratory function in patients with chronic obstructive pulmonary disease (COPD). We designed a placebo-controlled crossover study to compare the effects of a new benzodiazepine, estazolam ('ProSom'), with those of flurazepam ('Dalmane') on cardiopulmonary function in COPD patients. 29 patients completed all treatment phases (estazolam 2 mg, flurazepam 30 mg or placebo). Respiratory and cardiovascular function were assessed in awake patients on days 1 and 5 (acute and cumulative effects). Eight patients were also assessed during sleep in each period. The effects of estazolam and flurazepam on ventilatory response to CO2 and mouth occlusion pressure were no different from those of placebo. However, acute administration of flurazepam lowered tidal volume and increased inspiratory flow. Although no clinical signs of respiratory depression were observed with any long term treatment, flurazepam decreased oxygen saturation and inspiratory time and increased respiratory frequency. Neither drug altered breathing control during sleep. Our results indicate that estazolam 2 mg is equally as safe a hypnotic agent as flurazepam for patients with mild COPD.

In order to examine the relationship of dyspnea to anxiety and depression, the authors rated dyspnea using several methods in 50 patients with chronic respiratory impairment. Anxiety and depression were measured by the Symptom Checklist-90 and the Symptom Questionnaire. Results varied with the method of assessing dyspnea. Physician-rated dyspnea was significantly associated with patients' self-ratings of breathlessness as well as with pulmonary function tests, but not with any of the self-rating scales of emotions. Self-rated breathlessness was significantly associated with self-rated depression. In multiple regression analyses, depression was predictive of breathlessness. When the sample was limited to patients with chronic obstructive pulmonary disease, the results remained the same. The patients were significantly more depressed and anxious than matched family practice patients. In the study of the complex relationship of dyspnea to physical and emotional factors, it is desirable to use more than one measure of dyspnea because the results depend in part on the method of assessment.

A closed-claim analysis of anesthetic-related deaths and permanent injuries in the dental office setting was conducted in cooperation with a leading insurer of oral and maxillofacial surgeons and dental anesthesiologists. A total of 13 cases occurring between 1974 and 1989 was included. In each case, all available records, reports, depositions, and proceedings were reviewed. The following were determined for each case: preoperative physical status of the patient, anesthetic technique used (classified as either general anesthesia or conscious sedation), probable cause of the morbid event, avoidability of the occurrence, and contributing factors important to the outcome. The majority of patients were classified as American Society of Anesthesiologists (ASA) status II or III. Most patients had preexisting conditions, such as gross obesity, cardiac disease, epilepsy, and chronic obstructive pulmonary disease, that can significantly affect anesthesia care. Hypoxia arising from airway obstruction and/or respiratory depression was the most common cause of untoward events, and most of the adverse events were determined to be avoidable. The disproportionate number of patients in this sample who were at the extremes of age and with ASA classifications below I suggests that anesthesia risk may be significantly increased in patients who fall outside the healthy, young adult category typically treated in the oral surgical/dental outpatient setting.

For the induction of anesthesia in neurosurgical patients, the choice between thiopental and midazolam cannot be done on the basis of their respective cardiovascular, respiratory or cerebral effects, since they are similar. Among the advantages of midazolam are the absence of histamine release and excitatory effects. On the contrary the onset and the duration of action as well as the intensity of sedation are less predictable with midazolam when compared to thiopental. Therefore thiopental remains the first drug of choice in this clinical setting. For preoperative sedation in neurosurgical patients, the use of benzodiazepines should be limited, since they can induce respiratory depression mainly in patients with cranial trauma or with chronic obstructive pulmonary disease. The preoperative administration of a benzodiazepine in neurosurgical patients who are under chronic treatment should be decided individually, according to the level of the conscience of the patient and on the half life of the drug.

Many clinical nurse specialists (CNSs) are involved in providing group teaching programs for individuals with chronic obstructive pulmonary disease (COPD). Although knowledge levels often are enhanced by these programs, what is less well known is whether such programs also can affect the coping methods used by those with this disease. The exploratory study described here was part of a larger research project aimed at determining patients' knowledge, specific psychological parameters (anxiety, hostility, depression), and coping strategies. Thirty people agreed to participate in the study. The Jalowiec Coping Scale (JCS) (Jalowiec & Powers, 1981) was used so that participants could rate each coping method according to the degree of use and to determine whether the methods employed were affective or problem-solving approaches. There was very little change in the pre- and posttest scores on the JCS, indicating that there was little change in coping strategies used. There also were no significant correlations between the JCS scores and the demographic characteristics of age, educational level, and the length of time since diagnosis of COPD. The results of this study seem to indicate that pulmonary rehabilitation programs should place more emphasis on appropriate coping strategies that the COPD patient can incorporate into his or her lifestyle.

This study assessed physiologic, psychological, and cognitive functioning in outpatients with COPD. Sixty-four subjects, 53 to 82 years of age, participated in the 30-day exercise rehabilitation program. The program consisted of exercise, education and psychosocial counselling. Participants were assessed prior to beginning the program and at the end of 30 days. Assessments at both times included physiologic functioning (bicycle ergometry testing, pulmonary function tests, 12-min walk), psychological well-being (anxiety, depression, psychiatric symptoms, perceived well-being) and an abbreviated neuropsychological test battery. Results indicate significant improvement in physical endurance and pulmonary function, significant reductions in symptoms of depression and anxiety, and improvement in measures of general well-being and neuropsychological functioning. The study suggests that exercise rehabilitation of older adults with COPD contributes not only to improvements in physical functioning and endurance, but also to enhanced cognitive functioning and psychological well-being.

Serious respiratory depression may occur in patients with chronic obstructive pulmonary disease (COPD), receiving hypnotics during acute exacerbations. However, in a previous study on oxygenation during sleep in patients with stable hypoxemic non-hypercapnic COPD, we were unable to demonstrate a significant negative effect from single doses of nitrazepam and flunitrazepam. We have now investigated the effects of propiomazine, a phenothiazine hypnotic, in a double-blind randomized cross-over study of oxygen saturation and apneas during sleep and other sleep variables in 12 non-obese hypoxemic but clinically stable theophylline-treated COPD patients (PaO2 8.1 kPa, PaCO2 5.6 kPa, FEV1 31% of predicted value). None of the respiratory variables were adversely affected by a single oral dose of 25 mg propiomazine, whereas total sleeping time and the sleep efficiency index increased.

We evaluated the psychological status of chronic obstructive pulmonary disease patients with chronic respiratory failure, who were qualified for or on long-term oxygen therapy. Forty eight patients were examined. The patients' psychological status was assessed by means of the following methods: detailed clinical interview, the Taylor Manifest Anxiety Scale (MAS), Beck's Depression Inventory, and Tylka's Psychological Evaluation of Rehabilitation Efficiency Scale (SOPER). The study demonstrated that the great majority of patients presented a high degree of anxiety, depression and psychological tension, had low self-esteem and did not believe in the efficiency of therapy.

In advanced chronic obstructive lung disease (COLD), sodium retention is common, associated with reduction in renal plasma flow (RPF) and stimulation of the renin-aldosterone (PRA-PA) system, two abnormalities due to or influenced by hypercapnia: the independent role of hypoxemia in perturbing sodium homeostasis is unknown. In five stable patients with COLD (FEV1 = 0.9 +/- 0.21, mean +/- SE) with mild edema, during two weeks of a low sodium diet (one week on room air: pH = 7.39 +/- 0.02; PaO2 = 55 +/- 4 mm Hg; PaCO2 = 49 +/- 4 mm Hg; and one week on O2: pH = 7.38 +/- 0.01; PaO2 = 72 +/- 6 mm Hg; PaCO2 = 52 +/- 4 mm Hg) we monitored sodium balance, systemic and renal hemodynamics, plasma sodium and potassium, PRA, PA, and atrial natriuretic hormone (ANH). During air breathing, patients uniformly showed a depression of RPF despite normal cardiac output; plasma hormone levels did not differ from controls but there was elevation (greater than 2 SD above the normal mean) of PRA in four patients, PA in two patients, and ANH in two of five patients. During O2 breathing, urinary sodium increased significantly from 67 +/- 7 to 102 +/- 10 mEq/24 h. Surprisingly, the patients experienced a small but significant weight gain (0.6 +/- 0.1 kg). None of the other variables was affected by O2 therapy. The following conclusions were reached: in advanced COLD, correction of hypoxemia results in sodium diuresis, indicating that hypoxemia (in the presence of hypercapnia) contributes to sodium retention. The mechanism for this beneficial effect of O2 will require further investigation.
