Randomized Controlled Trial Comparative Study
New method of chest compression for infants in a single rescuer situation: thumb-index finger technique.
We introduce a new method of external chest compression (ECC), an essential part of cardiopulmonary resuscitation, using a thumb and index finger method (TIFM) on infants, and compares, this with two standard methods of the two finger method (TFM) and the two-thumb encircling hands method (TTEM). Sixty trained PALS (Pediatric Advanced Life Support) providers were randomly assigned into three groups and provided one-rescuer ECC for a period of five continuous minutes. Results without coaching or feedback were recorded on a recording CPR simulator (Laerdal, Inc). ⋯ The same parameters in the TTEM and new TIFM groups during this study were in accordance with the parameters recommended by the guidelines. Thus, our new TIFM technique of chest compression, in infants was shown to be better than the currently TFM, especially for achieving adequate compression depth and avoiding fatigue, and is equally as effective as the TTEM. We propose this new method (TIFM) should be considered as the method of choice in single rescuer situations.

Randomized Controlled Trial Multicenter Study Clinical Trial
A prospective, randomized clinical trial of preoperative bowel preparation for elective colorectal surgery--comparison among oral, systemic, and intraoperative luminal antibacterial preparations.
During a one year and six month period, 137 patients undergoing elective colorectal surgery for carcinoma were randomly allocated to three groups. Patients in group A received oral tobramycin and metronidazole for three days prior to surgery. Patients in groups B and C received systemic antibiotic, a second generation cephem cefmetazole, every 3 hours during surgery. ⋯ Although the preoperative bowel preparation taken for patients in group A could not sufficiently reduce the intestinal bacterial count, systemic antibiotic prophylaxis was simple and cost-effective. There was no additional advantage in combining the systemic and luminal antibiotic preparations. Therefore, for elective colorectal surgery, we recommend intravenous infusion of second generation cephem cephmetazole with mechanical bowel preparation.
