Randomized Controlled Trial Comparative Study
Ultrasound guidance for radial arterial puncture: a randomized controlled trial.
STUDY OBJECTIVE AND BACKGROUND: Arterial puncture for blood gas analysis is a frequent procedure and could be difficult in the emergency setting. The aim of the study was to compare ultrasonographically guided arterial radial puncture vs conventional sampling. ⋯ Ultrasonographically guided arterial puncture increases the number and duration of implementations. This technique, however, does not alter the patient's pain, the number of immediate complications, or patient and physician satisfaction.

The present study was designed to evaluate the effects of ulinastatin (UTI) on cardiac dysfunction after cardiopulmonary resuscitation (CPR). ⋯ The progression of proinflammatory responses, oxidative stress, and myocardial injury have been linked to the reduced EF after VF/CPR, and the administration of UTI at a cardioprotective dosage preserved the cardiac function after VF/CPR.

Shock index (SI), the ratio of heart rate to systolic blood pressure, has found to outperform conventional vital signs as a predictor of shock. Although age-specific vital sign norms are recommended in screening for shock, there are no reported age- or sex-specific norms for SI. Our primary goal was to report age- and sex-specific SI normal values for a nationally representative population 10 years and older by 5-year age groups. A secondary goal was to report SI normal values for children ages 8 to 19 years by 1-year age groups. ⋯ This first report of age- and sex-specific normal values for SI indicates that SI norms vary by age and sex. Just as age-specific vital sign norms are recommended in screening for shock, our findings suggest that age- and sex-specific SI norms may be more effective in screening for shock than a single-value threshold.
