Severe acute pulmonary edema is a medical emergency that requires immediate action on the part of the health care provider. Endotracheal intubation and mechanical ventilation remain the primary method of respiratory support in the most severe cases when respiratory failure ensues. Two cases of respiratory failure resulting from severe acute pulmonary edema are presented in which mechanical ventilation was indicated but the patients were treated instead with noninvasive bilevel positive pressure ventilation, which subsequently reversed their inspiratory failure. The use of noninvasive bilevel positive pressure ventilation in the emergency treatment of respiratory failure secondary to severe acute pulmonary edema is discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of tetracaine-adrenaline-cocaine (TAC) with topical lidocaine-epinephrine (TLE): efficacy and cost.
Topical anesthesia in the form of TAC (tetracaine, adrenaline, cocaine) solution has been used for wound repair. This pilot study was designed to determine if the topical anesthesia achieved using a mixture of lidocaine (5%) and epinephrine (1:2000) (TLE) is equivalent to the topical anesthesia obtained using a solution of tetracaine (0.5%), epinephrine (1: 2000), and cocaine (10.4%) (TAC). A prospective, randomized, double-blind trial was carried out from May 1992 to August 1992 at a community-based teaching hospital Emergency Department (ED) that receives 50,000 annual visits. ⋯ Seventeen patients were in the TLE group; 18 in the TAC group. The mean ages were compared and found to be similar (P = .40) between the two test groups. The pain scale values, the diameter of tissue blanch around laceration (halo size), and the time to laceration repair from the onset of application of anesthetic were compared and no difference was shown between the TAC and TLE groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Review Case Reports
Ovarian torsion: an unusual cause of abdominal pain in a young girl.
The case of a 6-year-old girl with right lower quadrant pain is presented. For several days, she had experienced pain that worsened and then was accompanied by vomiting and low-grade fever. Acute appendicitis was considered, but at laparotomy she was found to have a necrotic, torsed ovary. The natural history, clinical presentation, and diagnostic features of ovarian torsion are reviewed.

A study was conducted to determine the accuracy of tympanic thermometers for measuring the temperature of warmed fluids in fluid bags and in tubing at the delivery site (ie, beside the intravenous [IV] catheter). One-liter 0.9% saline bags were warmed in a microwave oven. A thermocouple electronic temperature probe was then used to measure the reference temperature. ⋯ Again, small differences were found on the order of 1 degree C. It was concluded that infrared thermometry is an accurate method for measuring the initial and delivery temperature of warmed fluids. Although tympanic thermometer measurements were statistically different from reference readings in certain temperature ranges, these differences were small and not clinically significant.(ABSTRACT TRUNCATED AT 250 WORDS)
