Parenteral nutrition in a pregnant cystic fibrosis patient.

This case report describes a 30-year-old pregnant woman with cystsic fibrosis who had marasmus as evidenced by clinical examination. The patient was maintained on central venous hyperalimentation for 18 days in her last trimester. The patient delivered a full-term infant via cesarian section with Apgar of 8 and 9, at 1 and 5 minutes, respectively, and adverse affects.

Magnetic resonance installation: siting and economic considerations.

The authors discuss the economics involved in operating a magnetic resonance (MR) imager in a 600-bed community hospital over a six-month period. Topics considered include patient monitoring; controlling access to the magnet room; depreciation and maintenance; cost of electricity, cryogenic liquids, and personnel; and charges for patient care. Conclusions are made regarding the current use of MR in a community hospital.

Respiratory center output and ventilatory timing in patients with acute airway (asthma) and alveolar (pneumonia) disease.

To investigate the mechanism for hyperventilation in two common but dissimilar conditions, asthma (A) and lobar pneumonia (P), we examined the ventilatory pattern in 17 A and six P subjects. When acutely ill, hyperventilation (PaCO2) was similar in the two groups. Minute ventilation (VE) however, was slightly greater in group A than in P.

Respiratory load compensation in uremia.

The clinical significance of respiratory-system load-compensation is unknown. We have measured the responses to random presentation of single, elastic inspiratory loads in 36 subjects: 8 normal personnel (N), 9 with obesity (O), 10 with chronic renal failure under hemodialysis (H), 5 with pneumonia (P), and 4 with interstitial lung disease (CILD). We have expressed these responses as: (1) the ratio of elastance (or rigidity) of the system during loaded breathing to the elastance without loading (E'RS/ERS); (2) the ratio of tidal volume (VT) achieved when breathing from an inspiratory load to the VT predicted in the absence of load compensation (VTL/VTP); (3) the ratio of inspiratory flow rates during loaded and unloaded breaths; (4) the ratio of inspiratory time of loaded and unloaded breaths.
