Adenosine for the prehospital treatment of paroxysmal supraventricular tachycardia.

STUDY OBJECTIVE: To determine the efficacy and feasibility of adenosine for the treatment of paroxysmal supraventricular tachycardia (PSVT) in the prehospital setting. DESIGN: Prospective case series. SETTING: Large, urban, advanced life support emergency medical services system. PARTICIPANTS: One hundred twenty-nine adult patients with PSVT, as identified by paramedic personnel. Pregnant patients and those taking carbamazepine or dipyridamole were excluded. INTERVENTIONS: Dose of 12 mg adenosine by rapid i.v. push followed by a 5-mL saline flush and a repeat dose of 12 mg adenosine i.v. push if the patient's rhythm remained unchanged. MEASUREMENTS AND MAIN RESULTS: Six-second lead II rhythm strips and vital signs were documented before and 2 minutes after the administration of adenosine. Demographic information, past medical history, medications, number of adenosine doses given, and complications were recorded by the paramedic on a case-report form. One hundred six of 129 (82%) of the case-report forms included the rhythm strips from before and after adenosine administration. Actual initial rhythms were determined by a consensus panel. The initial rhythms were PSVT in 79% (84 of 106) of patients, atrial fibrillation in 12% (13 of 106), sinus tachycardia in 5% (five of 106), atrial flutter in 2% (two of 106), and ventricular tachycardia in 2% (two of 106). Eighty-five percent (71 of 84) of patients in PSVT were successfully converted to sinus rhythms; four (5.6%) of these patients required a second 12-mg dose. One patient in atrial fibrillation spontaneously converted to normal sinus rhythm and one patient in ventricular tachycardia converted after adenosine. All other patients not initially in PSVT remained in their initial rhythm. Complications occurred in 12 of 129 patients and included chest pain (five), flushing (three), shortness of breath (two), nausea (one), anxiety (one), dizziness (one), headache (one), and seizure (one). All complications were transient and required no treatment. Prior history of PSVT was the only variable associated with a higher rate of conversion (P = .029). CONCLUSION: Paramedics are able to accurately identify PSVT using a single lead. Adenosine is safe and effective treatment for PSVT in the prehospital setting. This series is the largest prehospital study of adenosine use to date.

Vital signs as part of the prehospital assessment of the pediatric patient: a survey of paramedics.

Vital signs are an integral part of the field assessment of patients. A two-part study was undertaken to determine which vital signs are taken in the field assessment of pediatric patients and to determine whether the frequency of vital signs taken is influenced by base station contact, patient's severity of illness or injury, or paramedic demographic factors such as parenting and field experience. An initial pilot study of prehospital care records (run sheets) from two base hospitals in Los Angeles County revealed that there were significant differences between field vital sign assessment in pediatric and adult patients (P less than .0001). A retrospective review of 6,756 pediatric run sheets from Los Angeles County showed that the frequency of vital sign assessment varied with the age of the pediatric patient (P less than .05) (ie, the frequency of vital sign assessment increased correspondingly with the age of the patient). Base hospital contact occurred in 26% of the runs; when contact was made, vital signs were more likely to be taken in all age groups studied. Vital signs often were not assessed in children less than 2 years old, even if the patient's chief complaint suggested the possibility of a major illness or trauma. The second part of the study was a field assessment survey that was distributed to 1,253 active paramedics in Los Angeles County; the results showed that paramedics were less confident in their ability to assess vital signs in children less than 2 years old. Confidence increased with age of the patient.(ABSTRACT TRUNCATED AT 250 WORDS)

Violent death in the pediatric age group: rural and urban differences.

Violent death (homicide and suicide) in the pediatric age group is a major public health problem. A descriptive study was undertaken to review retrospectively the 1077 pediatric coroner's cases in 11 California counties for differences between urban and rural violent death rates. Pediatric violent death was more prevalent in the urban region than in the rural region (P less than 0.0007). High urban homicide rates accounted for most of this difference. Suicide rates were not significantly different (P = 0.18). Seventy-four percent of the violent deaths were in the 15- to 18-year age group, and most of these deaths were caused by firearms (81%). Blacks had the highest homicide and suicide rates. Child abuse was an important cause of death for young children in the urban area only. Socioeconomic factors, cultural differences, high population density, and the availability of firearms were proposed as factors affecting violent death in the pediatric age group.

Pediatric deaths and emergency medical services (EMS) in urban and rural areas.

A total of 1078 pediatric coroners' cases in 11 rural and urban California counties were reviewed as they relate to emergency medical services (EMS). Pediatric coroners' death rates per 100,000 population varied from an average of 2.17 in the rural region to 30.4 in the urban region. Vehicular accidents caused the majority (66%) of the accidental deaths, and firearms caused 61% of the violent deaths. Violent deaths (homicide and suicide) were significantly more common in the urban region (P less than 0.001), and vehicular deaths (excluding auto versus pedestrian) were more common in the rural region (P less than 0.001). EMS provider usage was greater in the urban areas (84 vs 66%, P less than 0.001), as was the number of cases receiving advanced life support (97 vs 66%, P less than 0.001). Urban and rural differences in place of death were significant for two places of death; street and highway, and inhospital deaths. A significantly greater number of children died on the street/highway in rural areas (P less than 0.05). Hospital deaths were more likely to occur on the ward in the rural region, versus the intensive care unit in the urban region (P less than 0.001). Proposed factors which may explain these findings include differences in medical resources and in local transfer policies. The study demonstrates that EMS providers are involved in the care of children who have had a fatal emergency. Further evaluation of rural and urban differences in prehospital care of the pediatric patient is indicated.
