Persons with increased intracranial pressure (ICP) from all causes are subject to periods of markedly increased pressure. Research since the initial clinical studies in the early 1960s has focused primarily on characteristics of ICP variations in specific pathologies and on mechanisms basic to increases in ICP rather than on the relationship between basic patient-care activities, such as moving the patient in bed, and variations in ICP. Therefore, nine patients with pressure-controlled ventriculostomy drainage systems were observed continuously for up to 24 hours to determine whate, if any, patient-nurse activities were associated with transient of sustained increased ICP. Frequencies of ventricular fluid drainage (VFD) during activity and nonactivity were compared to predicted frequencies. One patient had no VFD; eight patients had greater than predicted incidence of VFD associated with activity and less than predicted incidence associated with nonactivity. The difference between predicted and actual incidence of VFD was statistically significant (p less than .001) for all eight patients. Although each patient displayed individual patterns of specific activity associated with VFD, turning in bed and conversation about the patient's condition were consistent among the sample. Coughing, chewing use of bedpan, and restless movemenss were consistently associated with VFD in patients.

The purpose of this study was to determine whether adult patients with chronic obstructive pulmonary disease (COPD) can safely perform pulmonary hygiene measures without compromising their arterial oxygen saturation (SaO2) levels (less than 80 per cent). In 15 male veterans with moderate-to-severe COPD an ear oximeter was used to measure SaO2 levels while subjects completed a series of percussion, deep breathing, and coughing maneuvers in the head-down position (50 degree angle). No clinically significant changes in SaO2 levels were found in 14 subjects during pulmonary hygiene measures, but potentially dangerous symptoms were noted in two subjects. Our study supports the monitoring of objective and subjective symptoms during pulmonary hygiene and discontinuance of the procedure if tachycardia, palpitations, dyspnea, chest pain, or other distressful symptoms occur that might indicate hypoxemia.

Postoperatively, 19 adult open-heart surgery patients were interviewed as to information, included or not included in preoperative instruction, they identified as important to recovery. It was found that subjects desired details of all aspects of their conditions and treatment--preoperatively, operatively, and postoperatively. They had the greatest difficulty with pulmonary aspects of their care postoperatively. Subjects indicated a specific need for more information about the endotracheal tube, the ventilator, mucus, suctioning, deep breathing and coughing, and chest tube removal. Subjects experienced transient, primarily depressive, nonpsychotic postoperative mood changes unrelated to preoperative information, physical manifestations, and/or behavioral manifestations. Subjects regarded the nurse as an important provider of information and found the content of preoperative information satisfactory but wanted more individualization of instruction. They also indicated a need for more family involvement in preoperative instruction to provide them with information of the patient's progress throughout hospitalization. Questions and hypotheses for future research were generated.

In chronic bronchitis, disorders of the physical and chemical properties of mucus may contribute to bronchial obstruction. The abnormalities are analysed in sputum collected by physiotherapy. Measurements of the rheological properties (apparent viscosity and strain recovery), content analysis of secretory immunoglobulin A (S-IgA) and of serum albumin, and determination of the transport velocity of sputum on the ciliated frog palate provide reliable indices of the functional capacity of bronchial mucosa. The effectiveness of mucociliary clearance and coughing is analysed in patients by measuring the rate of removal of radioactive particles deposited on proximal airways. Different types of pathological secretions may be observed. In subjects with occasional cough and sputum, the secretions are characterized by a high content of S-IgA and serum albumin, and a high viscosity and low elasticity, reflecting their high degree of cross-linking. In chronic bronchitics, the S-IgA content and viscoelastic properties of sputum decrease as the illness progresses. During infection, purulent sputum exhibits high viscosity and low strain recovery. Such modifications of the rheological properties of mucus may impair mucociliary clearance. The role of the elastic component is predominant. Sputum, characterized by very low strain recovery (SR less than 4 units) or conversely by very high strain recovery (SR greater than 15 units), is transported at a low rate by mucociliary clearance. A marked hyperviscosity (no greater than 200 poises (120 N s m-2)) also appears as a limiting factor of the mucociliary clearance.

A survey of 300 grain elevator workers revealed that 77 per cent complained of eye symptoms; 64 per cent, of nasal symptoms; and 88 per cent, of one or more respiratory symptoms on exposure to airborne grain dust. Symptoms on exposure were independent of age and length of employment. Cough and wheezing on exposure were more common among smokers than nonsmokers (P less than 0.025). Nineteen per cent of the workers had had episodes of grain fever. The prevalence of chronic bronchitis was 37 per cent (42 per cent of smokers and 30 per cent of nonsmokers). Wheezes on auscultation were found in 23 per cent. Measurements of lung ventilatory function, as well as diffusing capacity, correlated significantly with age and smoking habits, but not with length of employment. Thirty-seven per cent of the workers had an abnormal mean forced expiratory flow during the middle half of the forced vital capacity (47 per cent of smokers and 13 per cent of nonsmokers), and 34 per cent had an abnormal maximal expiratory flow after exhalation of 50 per cent of the forced vital capacity (40 per cent of smokers and 13 per cent of nonsmokers), whereas only 13 per cent had an abnormal ratio of 1-sec forced expiratory volume to forced vital capacity. There was no correlation between precipitins to fungi, bacteria, grain, or grain dust antigens and acute or chronic respiratory symptoms, lung function, or grain fever. There was, however, a significant correlation between cutaneous reactivity to grain dust and wheezing on exposure (P less than 0.02). Abnormal flows at low lung volumes were more common among cutaneous reactors to common allergens. We concluded that exposure to airborne grain dust can cause acute inflammatory reaction to the exposed mucosa, and it is highly probable that grain dust contributes and, in some cases, causes chronic airway disease.

A questionnaire relating to smoking habits, respirator symptoms, and health attitudes was administered to 10 498 secondary schoolchildren in 1975. The results reported in this paper indicate that children who smoke regularly have a higher prevalence of upper respiratory tract infections and a higher incidence of the respiratory symptoms, cough, phlegm production with a cold, and shortness of breath, compared with non-smokers. Children are aware of the risks of lung cancer when smoking, but less aware of the other more immediate health risks, and this is particularly so in the younger age groups. It is suggested that health education should be directed towards younger children and that more use should be made of the fact that smoking clearly makes them less healthy.

In the former report on he calcium requirement in Small-for Date (S-f-D) infants it was observed that the ability of calcium absorption of S-f-D infants is lowered in 1-st semester of life. From this point of view it seemed purposeful to study the influence of 3 modified cow's milk formulas (see table) on the calcium absorption in S-f-D infants. Modification of these diets in regard to cow's milk depended on: 1) partial replacement of cow's milk fat with soya oil. 2) change of the proportion between fat and protein. 3) partial replacement of milk casein with lactoalbumin . The infants were divided into 3 groups G, H and C according to the kind of diet. Observation in the first 2 groups lasted for the whole first year of life, C group of infants was observed only in 1-st half year of life. In the first month of life G and H infants were fed the same unmodified cow's milk formulas (diet S) 3-day balance-studies. Were carried out once a month. The data of these 3 groups of infants were compared with each other and the data of S-f-D infants fed unmodified cow's milk formulas (group S) described in he former report. In group S, calcium intake was the highest in 1-st and in 2-nd semester of life among all compared infant groups, but the difference was not statistically significant. The lowest (%) absorption was noted in group G infants (fig. 2, table III and IV). The difference was statistically significant in 1-st semester of life between group G and S and in 2-nd semester between G and S as well as G and H groups. Calcium retention mg/kg was also the lowest in group G infants, and the difference was statistically significant in 1-st and in 2-nd semester between G and S groups. The infants fed H formula in spite of the lowest indices of calcium absorption % and retention mg/kg in the first (see table) and the second month of life and in spite of the lowest intake of calcium among all compared infants groups cough up absorption (%) and retention (mg/kg b.w.) with groups S in 2 semester of life.(ABSTRACT TRUNCATED AT 400 WORDS)

An uncommon, but lethal, toxic side effect of busulfan (Myleran) therapy for chronic myelogenous leukemia is pulmonary fibrosis. A 16-month-old male infant treated for 11 months with busulfan for chronic myelogenous leukemia is, we believe, the first case of "busulfan lung" in the pediatric age group to be reported. Progressive roentgenographic changes in the lung of a diffuse intra-alveolar and interstitial pattern were noted. The patient died after a four-day episode of cough, fever, and progressive dyspnea. At autopsy, no evidence of infection or leukemic infiltrates were seen in the lungs. Characteristic histologic findings as a result of busulfan therapy were observed in the lung and pancreas.

Three different low pressure cuffed endotracheal tubes (Lanz, Portex soft-seal, Kamen-Wilkinson) were studied in cadaver tracheas and patients in our intensive care unit during ventilation. In the air filled low pressure cuffs without controlled pressure system the cuff pressure and the ventilation pressure are almost identical. Rises of intrathoracic pressure during mechanical ventilation are reflected by increased cuff pressure. Tubes with controlled pressure system or foam-filled cuffs have lower peak cuff pressures, especially during sighing, coughing and suctioning.
