A study of 21 consecutive autopsy specimens of infants less than one year of age and weighing less than 6 kilograms was performed to determine the topographic anatomy and regional relationships of the central venous anatomy. This anatomy was compared with 14 additional autopsies performed upon older children. There was no significant difference in diameter between the internal jugular and subclavian venous system, on either the right or left side. ⋯ The findings of this study suggest that the internal and external jugular veins should be considered as safe and reliable portals for percutaneous entry into the central venous system in infants. In the infant less than one year of age, the difficult patient (for example, those with thrombocytopenia or severe pulmonary failure) or when the surgeon is less familiar with the infraclavicular approach, the veins of the neck may, in fact, be the site of choice. Additionally, we believe that a surgeon should not hesitate to switch to the internal or external jugular site after unsuccessful attempts at percutaneous entry into the subclavian vein.

A new method of rapid fluid resuscitation during thoracotomy performed in the emergency room.
A new technique for inserting and securing large bore intravenous lines directly into the right atrium, to be used in patients requiring a thoracotomy in the emergency room, is described herein. A plastic clip is attached to the edge of the atrial appendage and holds a large catheter in place. We have used this new technique successfully at the Cook County Hospital Trauma Unit and have encountered no complications to date.

Randomized Controlled Trial Comparative Study Clinical TrialPresumptive antibiotics for penetrating abdominal wounds.
The optimal antibiotic agent or agents for penetrating abdominal injuries remains undetermined. During the two year period ending April 1985, 150 consecutive patients undergoing celiotomy for penetrating abdominal trauma were prospectively randomized to receive either mezlocillin (4 grams every six hours) or clindamycin (600 milligrams every six hours) and gentamicin (loading dose of 2.0 milligrams per kilogram, then 1.5 milligrams per kilogram every eight hours). Antibiotics were begun in the emergency department with duration of coverage based upon the injury pattern--colon, five days; other hollow visceral injury, two days, and all others, one day. ⋯ Enterobacteriaceae, enterococcus and Bacteroides species were most frequently isolated. Infection was due to an organism resistant to the initial study regimen in one of the ten failures with mezlocillin and in two of the nine failures with clindamycin and gentamicin. Mezlocillin, a single agent broad spectrum penicillin, achieved comparable results with more expensive potentially toxic combination therapy for penetrating wounds.

The value of patient response to epidural steroid injection as a predictor of surgical outcome was studied. One hundred and eighty-seven patients with clinical signs of root compression underwent lumbar epidural steroid injection. Eighty-five of these patients had been told that an operation on the lumbar spine would be necessary. ⋯ A statistical comparison of these two groups revealed the probability of these occurrences of 0.088. There was no correlation between outcome of open surgical procedures and response to epidural steroids. Epidural steroid injection may be a valuable aid to predicting the outcome of chemonucleolysis.

A retrospective review of patients admitted with sternal fractures without massive trauma to the chest or hypotension was undertaken. Chest pain was present in 59 of 60 patients while external signs of bruising were noted in one-third. The standard anteroposterior (AP) roentgenogram of the chest was diagnostic in all patients. ⋯ Sternal fractures result from high energy trauma and should be suspected in patients with chest pain after blunt thoracic trauma. The lateral roentgenogram of the chest is the most useful diagnostic test. There is a high incidence of associated cardiac and noncardiac injuries in these patients mandating close observation with ECG monitoring in the intensive care unit.
