Chest physiotherapy in the neonate: a controlled study.

Abstract

The effect of postural drainage alone was compared to postural drainage with chest percussions on the arterial blood gases of 20 neonates with respiratory distress. There was no significant alteration in the arterial PO2 following postural drainage alone, with a significant increase (14.5 mm Hg) following postural drainage with chest percussions. The PO2 midway through postural drainage with percussions showed a small (5 mm Hg) but nonsignificant rise in the PO2, suggesting a gradual improvement throughout the use of this form of therapy. There was no significant change in the pH or PCO2 with either procedure. Appropriately performed chest percussions will result in an improvement in oxygenation in neonates with respiratory distress.

Traditional Foley drainage systems--do they drain the bladder?

PURPOSE: Foley catheters are assumed to drain the bladder to completion. Drainage characteristics of Foley catheter systems are poorly understood. To investigate unrecognized retained urine with Foley catheter drainage systems, bladder volumes of hospitalized patients were measured with bladder scan ultrasound volumetrics. Additionally, an in vitro bench top mock bladder and urinary catheter system was developed to understand the etiology of such residual volumes. A novel drainage tube design that optimizes indwelling catheter drainage was also designed. MATERIALS AND METHODS: Bedside bladder ultrasound volumetric studies were performed on patients hospitalized in ward and intensive care unit. If residual urine was identified the drainage tubing was manipulated to facilitate drainage. An ex vivo bladder-urinary catheter model was designed to measure flow rates and pressures within the drainage tubing of a traditional and a novel drainage tube system. RESULTS: A total of 75 patients in the intensive care unit underwent bladder ultrasound volumetrics. Mean residual volume was 96 ml (range 4 to 290). In 75 patients on the hospital ward mean residual volume was 136 ml (range 22 to 647). In the experimental model we found that for every 1 cm in curl height, obstruction pressure increased by 1 cm H2O within the artificial bladder. In contrast, the novel spiral-shaped drainage tube demonstrated rapid (0.5 cc per second), continuous and complete (100%) reservoir drainage in all trials. CONCLUSIONS: Traditional Foley catheter drainage systems evacuate the bladder suboptimally. Outflow obstruction is caused by air-locks that develop within curled redundant drainage tubing segments. The novel drainage tubing design eliminates gravity dependent curls and associated air-locks, optimizes flow, and minimizes residual bladder urine.
