Ambulance crashes delay patient transfer and endanger patients, ambulance crews, and other road users. In low- and middle-income countries, where motor vehicle crash rates are typically high, ambulances have a high risk of being involved in a crash. This case report describes an ambulance crash in Thailand to elucidate modifiable problems in current protocols and practices of emergency medical services. ⋯ In November 2016, a 28-year-old male driver of an ambulance died in a crash while transferring a female patient with dizziness to a rural hospital. The driver and another ambulance crew member were sitting in the front seats unrestrained. The other occupants were in the patient compartment unrestrained. The driver was driving the ambulance within the speed limit. He made a sharp turn trying to evade a dog, and the ambulance crashed head-on into a roadside tree. The cabin sustained severe damage, and the occupants in the patient compartment were struck against the compartment wall and were struck by unsecured equipment and the stretcher. The driver sustained a severe brain injury. The other occupants, including the female patient, sustained minor injuries. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case raises safety issues concerning the following aspects of ambulance operations in low- and middle-income countries: speed limit, safety device use, seatbelt use, securing equipment, and vehicle safety standards. Systematic measures to change protocols or even legislation, as well as data collection, are required to address these issues.

Observational Study
Use of Prophylactic Ondansetron with Intravenous Opioids in Emergency Department Patients: A Prospective Observational Pilot Study.
The current literature suggests that the prophylactic use of antiemetics is ineffective at preventing nausea or vomiting caused by opioids in the emergency department (ED). While there is no data evaluating ondansetron's efficacy for preventing opioid-induced nausea and vomiting, this practice remains common despite a lack of supporting evidence. ⋯ Our trial found that ondansetron did not appear to be effective at preventing opioid-induced nausea or vomiting. These findings and previous literature suggest prophylactic ondansetron should not be given to ED patients who are receiving IV opioids.

Response time interval (RTI) and scene time interval (STI) are key time variables in the out-of-hospital cardiac arrest (OHCA) cases treated and transported via emergency medical services (EMS). ⋯ Prolonged STI in OHCA with a delayed response time had a negative association with survival outcomes in four Asian metropolitan cities using the scoop-and-run EMS model. Establishing an optimal STI based on the response time could be considered.

An optimized protocol to help dispatchers identify potential cases of cardiac arrest and provide phone instructions for cardiopulmonary resuscitation (CPR) may increase the provision of bystander CPR, further improving the survival rate and neurological outcomes. ⋯ The study found this DA-CPR protocol, which includes continuous quality control, is promising as it improved the successful recognition of cardiac arrests.

Hematometrocolpos caused by an imperforate hymen is a common form of vaginal outflow obstruction. This is a rare pediatric anomaly that can present with atypical or vague symptomatology, such as abdominal pain or constipation or urinary retention in the setting of amenorrhea. It is essential to obtain a gynecologic history and inquire about menstrual cycles to properly evaluate a young female with such a common complaint as abdominal pain. Failure to perform a gynecologic examination in the emergency department setting may delay diagnosis and appropriate care for this rare condition, which can lead to serious complications. ⋯ This case describes a 12-year-old female who presented to the emergency department with a complaint of abdominal pain and urinary symptoms. Because of the severity of the patient's pain on abdominal examination, we obtained a computed tomography scan of her abdomen and pelvis, which showed findings consistent with hematometrocolpos. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Obstruction of the female genital outflow tract is a rare occurrence. Because abdominal pain is such a common complaint, not only in the pediatric emergency department but also in the outpatient setting, the diagnosis of hematometrocolpos may easily go undiagnosed for months or even years. Obtaining a complete gynecologic history is key when evaluating young females with abdominal pain or urinary retention. Early detection and timely management can prevent serious complications and long-term sequelae. This patient had a successful outcome and early surgical management of her hematometrocolpos which was caused by an imperforate hymen.
