Comparative Study
Hyponatremia in sick children seeking pediatric emergency care.
This prospective study evaluated the frequency, clinical characteristics and causes of hyponatremia (serum sodium < 130 mEq/L) in 727 children upto 12 years of age, who were brought for emergency care, and needed hospitalization. Hyponatremia was found in 29.8% and was more frequent in summer (36%; 123/341) than in winter (24%; 94/386) (p < 0.001). ⋯ Clinical evaluation and concurrent plasma and urinary osmolality and urine sodium suggested that hyponatremia associated with pneumonia, meningitis/encephalitis, septicemia, seizures and miscellaneous diseases was of hypotonic-euvolemic (dilutional) type in more than 80% patients while in all children with acute diarrhea it was of hypovolemic type. The study has shown that hyponatremia occurs frequently in sick children requiring emergency care, especially in summer months, and should receive appropriate attention in the management plan.

Comparative Study
Use of a pro forma for head injuries in the accident and emergency department--the way forward.
The aim of this study was to assess the quality of documentation of head-injured patients seen in three accident and emergency (A&E) departments using a specially designed head injury pro forma. A 4-week prospective study of a single head injury pro forma was followed by a second similar study with an improved version (two head injury pro formas, one for young children and babies, the other for older children and adults). The main outcome measures were the degree of completion of the pro forma and questionnaire responses from receptionists, nurses and doctors. ⋯ The pro forma was generally well received by A&E staff, particularly after recommended improvements were made, and the majority of staff felt it should be introduced permanently into the A&E department. Concern about its use in cases of very minor head injury and multiple injuries were raised. As well as improved documentation, the pro forma facilitates the process of audit and may have an important role to play in information technology and computers in the future.

Early thrombolytic therapy after acute myocardial infarction is important in reducing mortality. To evaluate a system for reducing in-hospital delays to thrombolysis pain to needle and door to needle times to thrombolysis were audited in a major accident and emergency (A and E) department of a district general hospital and its coronary care unit (CCU), situated about 5 km away. Baseline performance over six months was assessed retrospectively from notes of 43 consecutive patients (group 1) transferred to the CCU before receiving thrombolysis. ⋯ The incidence of adverse effects was not significantly different. Nine deaths occurred (six in group 1, three in group 2b), an in-hospital mortality of 9.9%. Thrombolysis can be safely instituted in the A and E department in selected patients, significantly reducing delay to treatment.

Multicenter Study Comparative Study
Emergency-department diagnosis of acute myocardial infarction and ischemia: a cost analysis of two diagnostic protocols.
To assess the potential cost savings of the emergency-department (ED) diagnosis of acute myocardial infarction (AMI) and other myocardial ischemia using a nine- hour ED evaluation protocol. ⋯ At both centers, hospital charges related to the acute evaluation of chest pain were significantly lower with this ED diagnostic protocol for AMI and myocardial ischemia.

The objective of this study was to examine the use of limited, goal-directed, two-dimensional ultrasound studies performed by emergency physicians and to assess the frequency, variety, and accuracy of their readings. A 1-year prospective study was performed by using an emergency department (ED) ultrasound machine with a 3.5-mHz mechanical oscillating sector transducer and a 5.0-mHz vaginal transducer. In a series of proctoring sessions, radiologists trained emergency physicians to do limited, goal-directed ultrasonography. ⋯ Eleven categories of ultrasound use were reported. The three studies most commonly performed were for gallbladder disease (53%), intrauterine pregnancy (28%), and abdominal aortic aneurysms (7%). Accuracy of ED gallbladder ultrasonograms for 65 patients showed a sensitivity of .86, specificity of .97, PPV of .97, and NPV of .85.(ABSTRACT TRUNCATED AT 250 WORDS)
