Case Reports
Relief by naloxone of morphine-induced spasm of the sphincter of Oddi in a post-cholecystectomy patient.
Spasm of the sphincter of Oddi is a well-recognized effect of the narcotic class of drugs. Although it is usually clinically silent, such spasm occasionally causes debilitating pain that may be mistaken for more serious disorders. We present the case of a patient who had undergone cholecystectomy previously, but in whom morphine given in the Emergency Department precipitated pain consistent with biliary colic; the pain resolved promptly after administration of naloxone. This entity may considered in the differential diagnosis of acute onset of colicky abdominal pain in the patient given narcotics.

Case Reports
Gastric rupture and massive pneumoperitoneum after bystander cardiopulmonary resuscitation.
Gastric perforation is a rare complication of cardiopulmonary resuscitation. The majority of reported cases have been associated with difficult airway management or esophageal intubation. There has been only one previous case report in which this complication could be attributed solely to mouth-to-mouth ventilation. We present a case of simple bystander cardiopulmonary resuscitation that resulted in gastric perforation.

To determine paramedics' experience, comfort, and accuracy in the estimation of pediatric weights, paramedics were surveyed regarding their experience and training in estimating pediatric weights and then were presented with four children and asked to estimate their weights and to calculate the first round of i.v. epinephrine dose for asystole according to protocol. Twenty paramedics participated, with 55% stating they were uncomfortable on pediatric calls; 15 of 20 (75%) stated they were uncomfortable estimating children's weights. The majority of estimations were within 50% of the actual weights. ⋯ In 10% of cases, the epinephrine dose was incorrect by a factor of 10 times the appropriate dose. The weight range using the Broselow tape was determined correctly by all participants, with 95% correctly reporting the correct dose of epinephrine. Overall, paramedics were accurate in estimating pediatric weights, and use of the Broselow tape improved the precision of these estimations.
