Randomized Controlled Trial Clinical Trial
Effect of point of care testing on length of stay in an adult emergency department.
Devices are now available that are practical for point of care testing (PCT) in hospital settings. Previous studies in clinical settings, however, have failed to demonstrate a reduction in patients' length of stay (LOS) associated with the use of PCT. This randomized controlled study compared PCT with central laboratory testing in a hospital Emergency Department to assess the difference in patients' LOS. ⋯ The median stay associated with PCT was significantly shorter. Among patients who were destined to be discharged home, there was also a significantly shorter stay, but not among those who were destined to be admitted. It was concluded that the use of PCT can achieve significant time savings in an Emergency Department.

Randomized Controlled Trial Clinical Trial
Prescription noncompliance: contribution to emergency department visits and cost.
We randomly surveyed 100 patients in the acute care section of a large urban university hospital Emergency Department (ED) on 6 days with regard to the existence of and reasons for prescription noncompliance. Noncompliance was considered a major factor contributing to the ED visit if: (1) no medications had been taken for at least 48 h before the ED visit; (2) the medications, when previously taken, had routinely controlled the condition for which the patient was presenting to the ED; and (3) no other significant cause or illness was believed to have precipitated the ED visit. ED, admissions, and yearly medication costs were calculated for all patients. ⋯ Six noncompliant patients were admitted at an average cost of $4,834.62. The average cost of a year's medication was $520.72. Noncompliance with drug prescriptions is a significant contributor to ED visits and health care costs.

Randomized Controlled Trial Clinical Trial
Use of the Trousseau dilator in cricothyrotomy.
When performing cricothyrotomy, once the initial incision has been created, the scalpel handle may be inserted into the incision and rotated, or a Trousseau dilator may be used to widen the opening. During endotracheal (ET) tube passage, the Trousseau dilator may be left in place or a tracheal hook may be inserted for tracheal stabilization. This experimental crossover trial of cricothyrotomy in a cadaver model compared: 1) scalpel handle rotation to the use of a Trousseau dilator in widening the initial incision, and 2) the use of a tracheal hook to a Trousseau dilator during ET tube passage. ⋯ We found that the average size of the largest ET tube passed was significantly greater with the use of a tracheal hook (internal diameter mean 7.0 mm, median 7.0 mm) than with a Trousseau dilator (internal diameter mean 5.7 mm, median 5.5 mm). There was no damage to local tissue and no cuff ruptures. We conclude that the scalpel handle rotation technique is equal to the use of the Trousseau dilator with regard to opening size and maximal ET tube size but that use of a tracheal hook rather than a Trousseau dilator allows for passage of a larger ET tube in a cadaver model of cricothyrotomy.

Randomized Controlled Trial Clinical Trial
A randomized controlled trial of buffered lidocaine for local anesthetic infiltration in children and adults with simple lacerations.
This study assessed the efficacy of buffered lidocaine in children and adults for the repair of simple lacerations. We compared plain lidocaine (PL) with buffered lidocaine (BL) in a prospective, randomized, double-blind, placebo controlled trial. Children had a 10-point pain score assessed by a nurse using predetermined behavior criteria, and a visual analog pain score (VAS) as perceived by the parent. ⋯ In 136 children, the median nurse-rated pain score was 4.5 for both PL and BL. The parent's median VAS was 4.5 for PL and 4.0 for BL. In contrast to previous studies, we conclude that buffered lidocaine does not reduce infiltration pain in children or adults.

Randomized Controlled Trial Comparative Study Clinical Trial
Cricothyrotomy technique: standard versus the Rapid Four-Step Technique.
Standard cricothyrotomy technique uses a tracheal hook cephalad to the opening to stabilize the trachea during endotracheal (ET) tube passage. A newly described Rapid Four-Step Technique (RFST) uses the tracheal hook caudal to the opening to stabilize the trachea during ET tube passage. This experimental crossover trial compared standard cephalad tracheal hook traction to caudad traction as recommended by RFST in a cadaver model of cricothyrotomy. ⋯ There was no significant difference between maximal ET tube sizes for standard technique (median size 7.0, mean 6.95 mm internal diameter) versus RFST (median size 7.0, mean 6.82 mm internal diameter). We conclude that RFST may be associated with a higher incidence of complications than standard technique as demonstrated by our cadaver model of cricothyrotomy. We were unable to demonstrate a difference between the two techniques with regards to size of ET tube able to be passed.
