Initial resuscitation volume in uncontrolled hemorrhage: effects on organ function.
Conventional resuscitation of hypovolemia due to hemorrhage has consisted of aggressive fluid administration. Recent studies have suggested that surgical control of bleeding before fluid resuscitation might improve early survival. The effects of limited resuscitation on organ function have not been assessed in these studies. ⋯ No histologic differences could be discerned between the groups. Hematocrit and indices of liver and renal function were similar in all groups, and no animal developed organ dysfunction. In this model of moderate uncontrolled intraperitoneal hemorrhage, the volume of fluid resuscitation, or the absence of resuscitation, had an inconsistent effect of 7-day survival and did not influence function or histologic appearance of the liver, lungs, or kidneys 7 days after hemorrhage.

A reevaluation of the radiographically detectable complications of percutaneous venous access lines inserted by four subcutaneous approaches.
As a result of prior studies elucidating the potential complications associated with the use of central venous access lines, the Food and Drug Administration and the manufacturers themselves have published guidelines and warnings outlining these dangers and describing the safest insertion techniques. We will attempt to determine whether this improved education has altered the number and type of complications, comparing the results from different types of hospitals, among the various medical services and among operators with varying degrees of experience. This is a prospective analysis of all central venous pressure (CVP) and Swanz-Ganz catheters (SGCs) inserted between July 1, 1995, and February 30, 1996, at a regional Veteran's Affairs hospital and an inner city university medical center. ⋯ Venous access catheter tip malpositions are very common in all settings, but easily recognized by radiography, whereas PTXs are unusual. In contrast to most older studies, PTXs are more frequently observed with internal jugular as opposed to subclavian cannulations and with SGCs rather than CVP lines. However, our data support prior studies that the right atrium and distal right lower lobe pulmonary artery are the most common sites for CVP and SGC misplacement, respectively, and that there is an improvement in success rates with increasing operator experience.

Increased efficiency and cost-effectiveness in the evaluation of the blunt abdominal trauma patient with the use of ultrasound.
The efficacy and effectiveness of ultrasound (US) in evaluating patients suspected of having blunt abdominal trauma are near that of computed tomography (CT) and diagnostic peritoneal lavage (DPL). Because no cost-effectiveness study has been reported, the purpose of this study was to demonstrate that US is more efficient and cost-effective than CT/DPL in evaluating blunt abdominal trauma. Over a 9-month period, 331 patients suspected of sustaining blunt abdominal trauma were evaluated at a Level I trauma center by US, CT, and/or DPL. ⋯ There was a significant difference in time to disposition with the US group being significantly lower (P = 0.001). The total procedural cost was 2.8 times greater for the CT/DPL group than for the US group. US is not only effective in diagnosing blunt abdominal trauma, but it is also more efficient and cost-effective than is CT/DPL.

A minimum 2-year follow-up retrospective review was undertaken to assess our experience with an anterior paramedian muscle-sparing approach to the lumbar spine for anterior spinal fusion (ASF). The records of 28 patients (November 1991 through January 1996) undergoing ASF via a left lower quadrant transverse skin incision (6-10 cm) with a paramedian anterior rectus fascial Z-plasty retroperitoneal approach were reviewed. Diagnosis, number, and level of lumbar interspaces fused, types of fusion, estimated blood loss, length of procedure, length of hospital stay, and complications were analyzed. ⋯ In three cases a mild ileus developed, which resolved spontaneously. We conclude that the anterior paramedian muscle-sparing retroperitoneal approach is safe, uses a small skin incision, avoids cutting abdominal wall musculature, and allows for multiple-level anterior spinal fusions by a variety of interbody fusion techniques. This approach does not require transperitoneal violation or added endoscopic instrumentation, nor does it limit fusion level and technique of fusion, as is the case with the recently popularized laparoscopic approach to the lumbar spine.
