Randomized Controlled Trial
Less painful arterial blood gas sampling using jet injection of 2% lidocaine: a randomized controlled clinical trial.
The aim of this study was to compare pain levels from arterial blood gas (ABG) sampling performed with or without application of lidocaine via jet injector. ⋯ Lidocaine jet injection provides beneficial and rapid anesthesia, resulting in less pain and a greater rate of successful ABG sampling. Therefore, it is recommended for use before ABG sampling to decrease the patient's pain and the number of unsuccessful attempts and to enhance the patient's satisfaction.

Randomized Controlled Trial Comparative Study
Effects of antithrombin and gabexate mesilate on disseminated intravascular coagulation: a preliminary study.
We hypothesized that antithrombin is more effective for disseminated intravascular coagulation (DIC) than is gabexate mesilate, which is a protease inhibitor, suggested from the previous studies. Initially, we compared the effects of antithrombin and gabexate mesilate for treating infection-related DIC. ⋯ Antithrombin may be a more effective treatment for coagulation and fibrinolysis disorders than gabexate mesilate in infection-related DIC, but there was no difference in 28-day mortality.

Randomized Controlled Trial
Precise minute ventilation delivery using a bag-valve mask and audible feedback.
The efficacy of a modified bag-valve mask (BVM) with a ventilation rate alarm system was compared with conventional BVM to maximize adequate minute ventilation volume delivery in a manikin model. ⋯ In a manikin arrest model, the use of RVBVM results in a more constant and regular minute tidal ventilation rate than the use of VBVM and is, therefore, expected to produce more favorable outcomes in practical resuscitative situations.
