Continuous, noninvasive measurement of pulsus paradoxus in patients with acute asthma

Article Abstract:

A noninvasive, objective method of measuring pulsus paradoxus (PP) in asthma patients may provide a useful means of determining asthma severity in research studies. Pulsus paradoxus is an abnormally large drop in blood pressure upon inhalation. Researchers correlated continuous finger arterial blood pressure monitoring with a device measuring chest expansion in 85 children aged 20 months to 17 years experiencing an asthma attack. PP correlated well with other measures of asthma attack severity. It correctly predicted 40% of the children admitted to the hospital and 90% of those not requiring admission.

Frozen oral hydration as an alternative to conventional enteral fluids

Article Abstract:

Frozen, flavored oral rehydration solution may be more effective than clear rehydration liquid for treating dehydrated children. Solutions of glucose and electrolytes in water can replace fluid lost through persistent vomiting or diarrhea, but many children vomit or refuse to drink them. Researchers offered 91 children, aged 6 months to 13 years, either unflavored solution or flavored, frozen rehydration "ice pops." Fifty-five percent of children given the frozen pops accepted and tolerated the full prescribed volume of solution, compared to only 11% of children who were offered the liquid.

Frequency of Digital Rectal Examination in Children With Chronic Constipation

Article Abstract:

Most children with chronic constipation are not appropriately examined by primary care physicians before they are referred to a pediatric gastroenterologist. Researchers reviewed the care of 128 children and found that 77% never had a digital rectal examination before referral. Impaction of stool in the colon was diagnosed by rectal examination in 54% of the children, and only 21% had no or minimal stool retention. The rectal examination can identify the likely causes of constipation and thereby direct the method of treatment.
