Computed tomography (CT) is currently the modality of choice in evaluating pancreatic injury in patients suffering abdominal trauma who do not require immediate exploration. The purpose of this study was to determine the reliability of initial CT scanning in the detection of pancreatic trauma. A retrospective review was performed of all patients admitted to two Level 1 trauma centers over a 10-year period. ⋯ The mean pancreatic injury by CT was 0.45 versus 2.0 on exploration (P < 0.001). Injury to the pancreas following blunt trauma is rare. Computed tomography will often miss or underestimate pancreatic injuries that require operative treatment, and normal findings on initial scan should not be relied upon to exclude significant pancreatic trauma.

Unnecessary preoperative investigations: evaluation and cost analysis.
In keeping with national efforts to curb escalating health care costs, the necessity of multiple preoperative investigations was evaluated in 60 randomly selected ambulatory surgery patient records. Necessity for testing was assessed on clinical indications, and overall cost was calculated from the rates at both the local Department of Veterans Affairs Medical Center (VAMC) and a community hospital. ⋯ Education of staff and housestaff is crucial to changing obsolete practice habits. The quality and safety of care would not be compromised by limiting preoperative investigations to only those with clinical indications.

Randomized Controlled Trial Comparative Study Clinical TrialFailure of antiseptic bonding to prevent central venous catheter-related infection and sepsis.
Infection associated with the use of triple lumen catheters in hospitals is a frequent and serious complication. The prevailing hypothesis for the origin of catheter-related infection (CRI) is bacterial colonization and subsequent infection of the skin insertion site and catheter interface. The recently released ARROWgard catheter contains a bonded synergistic combination of silver sulfadiazine and chlorhexidine, which is thought to render the catheter resistant to bacterial colonization and subsequent sepsis. ⋯ The rate of CRI for the ARROWgard was 10.9 per cent, compared with 12.9 per cent for the standard catheter (P = NS). The rate of CRS for the ARROWgard was 8.7 per cent, compared with 8.1 per cent for the standard catheter (P = NS). The coating of central venous catheters with silver sulfadiazine and chlorhexidine does not reduce the rate CRI or CRS when compared with standard central venous catheters in patients receiving TPN.
