Effect of Emergency Physician-Performed Point-of-Care Ultrasound and Radiology Department-Performed Ultrasound Examinations on the Emergency Department Length of Stay Among Pregnant Women at Less Than 20 Weeks' Gestation.

OBJECTIVES: We sought to confirm retrospective studies that measured an approximately 20% reduction in emergency department (ED) length of stay (LOS) in early-gestation pregnant women who receive emergency physician-performed point-of-care ultrasound (US) examinations rather than radiology department-performed US examinations for evaluation of intrauterine pregnancy (IUP). METHODS: A randomized controlled clinical trial was performed at an urban academic safety net hospital and 2 Naval medical centers in the United States. The allocation was concealed before enrollment. Clinically stable adult pregnant women at less than 20 weeks' gestation who presented to the ED with abdominal pain or vaginal bleeding were randomized to receive a point-of-care or radiology US to assess for IUP. The primary outcome measure was the ED LOS. RESULTS: A total of 224 patients (point-of-care US, n = 118; radiology US, n = 106) were included for the analysis. The ED LOS was 20 minutes shorter in the point-of-care US arm (95% confidence interval [CI], -54 to 7 minutes). Adjusting for variability due to the location, the ED LOS was calculated to be 31 minutes shorter (95% CI, -64 to 1 minute) than for patients in the radiology US arm. Excluding patients in the point-of-care US arm who crossed over to radiology US after an inconclusive point-of-care US examination, the ED LOS was 75 minutes shorter than in the radiology US arm (95% CI, -97 to -53 minutes). CONCLUSIONS: Early-gestation pregnant ED patients requiring pelvic US were discharged earlier when point-of-care US was used rather than radiology US; however, this trial did not achieve our target of 30 minutes. Nevertheless, our data support the routine use of ED point-of-care US for IUP, saving the most time if a conclusive IUP is identified.

Comparison of bag-valve-mask hand-sealing techniques in a simulated model.

STUDY OBJECTIVE: Bag-valve-mask ventilation remains an essential component of airway management. Rescuers continue to use both traditional 1- or 2-handed mask-face sealing techniques, as well as a newer modified 2-handed technique. We compare the efficacy of 1-handed, 2-handed, and modified 2-handed bag-valve-mask technique. METHODS: In this prospective, crossover study, health care providers performed 1-handed, 2-handed, and modified 2-handed bag-valve-mask ventilation on a standardized ventilation model. Subjects performed each technique for 5 minutes, with 3 minutes' rest between techniques. The primary outcome was expired tidal volume, defined as percentage of total possible expired tidal volume during a 5-minute bout. A specialized inline monitor measured expired tidal volume. We compared 2-handed versus modified 2-handed and 2-handed versus 1-handed techniques. RESULTS: We enrolled 52 subjects: 28 (54%) men, 32 (62%) with greater than or equal to 5 actual emergency bag-valve-mask situations. Median expired tidal volume percentage for 1-handed technique was 31% (95% confidence interval [CI] 17% to 51%); for 2-handed technique, 85% (95% CI 78% to 91%); and for modified 2-handed technique, 85% (95% CI 82% to 90%). Both 2-handed (median difference 47%; 95% CI 34% to 62%) and modified 2-handed technique (median difference 56%; 95% CI 29% to 65%) resulted in significantly higher median expired tidal volume percentages compared with 1-handed technique. The median expired tidal volume percentages between 2-handed and modified 2-handed techniques did not significantly differ from each other (median difference 0; 95% CI -2% to 2%). CONCLUSION: In a simulated model, both 2-handed mask-face sealing techniques resulted in higher ventilatory tidal volumes than 1-handed technique. Tidal volumes from 2-handed and modified 2-handed techniques did not differ. Rescuers should perform bag-valve-mask ventilation with 2-handed techniques.

Recurrent priapism from therapeutic quetiapine.

Priapism is rarely related to use of non-erectile related medications. The objective was to educate about the multiple possible causes of priapism and to provide treatment recommendations for the different types of priapism. We present the case of a 43-year-old African American male with a history of schizoaffective disorder who presented to our emergency department multiple times over a three year period with priapism, each episode related to the ingestion of quetiapine. Following penile aspiration and intercavernosal injection of phenylephrine, this patient had resolution of his priapism. This case demonstrates an unusual case of recurrent priapism.
