Comparative Study
Peer review organization payment denials: comparative analysis of emergency department and non-emergency-department admissions.
The Health Care Financing Administration has contracted with regional peer review organizations to review Medicare admissions and to deny payment for hospital admissions that fail to meet peer review organization criteria. The purpose of this study was to compare emergency department admissions with non-emergency-department admissions with respect to rates of peer review organization denial and the reasons for those denials. All hospital Medicare admissions between January 1984 and April 1987 were retrospectively reviewed. ⋯ Of the 11,865 non-emergency department, non-pre-authorized admissions, 333 (2.81%) were denied. Of these denials, 174 (52.2%) were appealed, 76 (43.6%) successfully. Overall, emergency department admissions were significantly less likely to receive peer review organization denial than non-emergency-department, non-pre-authorized admissions (P less than 0.003).(ABSTRACT TRUNCATED AT 250 WORDS)

Our purpose was to determine the forces required to insert several different styles of cricothyroid cannulas and to relate the magnitude of these forces and cannula design features to the incidence of complications during insertion. Tests were done on unembalmed cadavers and anesthetized dogs. Samples of 4 different commercial cricothyroid cannulas were tested. ⋯ A lubricant was applied to the cannulas in half of the dogs tested. Major findings are 1) there is a linear correlation between insertion force and device diameter, 2) higher puncture force is associated with a greater incidence of complications, 3) posterior wall penetration occurs more frequently with a curved penetrating device, 4) using small pilot needles to guide insertion of large cannulas minimizes complications, and 5) lubricant is less effective for cannulas having abrupt diameter changes. These findings provide guidelines for design of safer cricothyroid cannulas.

Residency programs routinely review cases involving "morbidity and mortality." It would be a valuable experience to similarly review medical malpractice cases and the associated testimony by medical experts. When available, the cases reviewed in residency programs would be those in which faculty members at the same institution had testified. The faculty member in such cases would be intimately familiar with the case and able to share the knowledge necessary to take part in the legal process. This case review process would expose residents to the legal realities of medical practice, provide a forum for peer review of legal testimony by experts, and show residents how to participate in the legal system should the need arise.

Randomized Controlled Trial Comparative Study Clinical Trial
Pain comparison of unbuffered versus buffered lidocaine in local wound infiltration.
The purpose of this study was to compare the pain of infiltration between unbuffered lidocaine and buffered lidocaine in a traumatic laceration. Solutions of unbuffered 1% lidocaine and buffered 1% lidocaine were randomly assigned to Site I or Site II of a single laceration for each subject, with the patient serving as self-control. ⋯ It was also found that Site I was preferred more often than Site II regardless of which medication was used. The conclusion is that buffered lidocaine is preferred over unbuffered lidocaine and that the order of injection is an important factor in trials that involve multiple sequential injections in the same patient.

Review Case Reports
Accidental hypothermia with cardiac arrest: recovery following rewarming by cardiopulmonary bypass.
A 22-year-old man eventually had a good neurologic recovery following prolonged coma after extracorporeal rewarming from profound hypothermia (24 degrees C) due to exposure. The patient was in full arrest for 60 minutes prior to institution of cardiopulmonary bypass (CPB). ⋯ Cardiopulmonary bypass is the current rewarming method of choice for severe hypothermia associated with a persistent nonperfusing cardiac rhythm. CPB provides the most rapid core rewarming with the additional benefit of circulatory support during the period of cardiac instability.
