Ineffectiveness of the measurement of 'routine' vital signs for adult inpatients with community-acquired pneumonia.

More frequent vital sign evaluation does not result in a statistically significant difference in survival or the number of transfers to the intensive care unit (for progression of disease) after adjusting for age, gender, duration of intravenous antibiotics and comorbid conditions.

Topical tetracaine prior to arterial puncture: a randomized, placebo-controlled clinical trial.

The objective of this randomized, double-blind, placebo-controlled clinical trial was to determine whether a topical anesthetic agent (tetracaine) provides effective local analgesia prior to radial arterial puncture. Tetracaine or placebo gel was applied 45 min prior to arterial puncture to patients who were referred for elective arterial blood gas. The primary outcome was the patient's perception of pain associated with the procedure as measured by a visual analog scale.

Ineffectiveness of measuring routine vital signs in adult inpatients with deep venous thrombosis.

The purpose of this study was to evaluate the benefit, if any, of routine monitoring of vital signs on clinical outcomes in hospitalized patients with deep venous thrombosis (DVT). One hundred forty-nine patients with DVT included in this study were categorized into two groups: those that underwent measurement of vital signs every 6 hours or those that had vital signs measured every 8 hours. Vital signs included pulse, blood pressure, respiratory rate, and temperature.
