Comparative StudyValue of preoperative coagulation tests: reappraisal of major noncardiac surgery.
In a retrospective case-control review, we evaluated preoperative coagulation testing in patients undergoing major noncardiac operations to determine if routine testing benefits this group of patients. The platelet count (PC), prothrombin time (PT), and activated partial thromboplastin time (aPTT) in all patients undergoing major noncardiac surgery over a 22-month period were reviewed. The review was done both manually and by the computerized hospital information system. ⋯ Although (compared to controls) patients with abnormal tests had more changes in their anesthesia plan (36% vs. 2%, p < 0.001) and platelet or fresh frozen plasma transfusions (50% vs. 9%, p < 0.001), blood loss and the incidence of bleeding complications were not different. We conclude that the use of preoperative coagulation tests in patients undergoing major noncardiac surgery should still be guided by clinical assessment. The surgical procedure itself does not constitute an indication for testing.

Penetrating thoracoabdominal injuries: ongoing dilemma-which cavity and when?
The aims of this study were to (1) define characteristics for the thoracoabdominal injury patient population; (2) describe sequences of surgical interventions with combined procedures (i.e., thoracotomy and laparotomy); and (3) describe pitfalls leading to inappropriate sequencing of surgical interventions for thoracoabdominal injuries. It was a retrospective 4-year study (January 1995 to December 1998) conducted at an urban level I trauma center. The study population comprised 254 patients who had sustained thoracoabdominal injuries requiring surgical intervention: 187 (73%) gunshot wounds (GSWs), 64 (25%) stab wounds (SWs), and 3 (2%) shotgun wounds (STWs). ⋯ It was concluded that penetrating thoracoabdominal injuries incur high mortality (31%), and the mortality doubles for patients who require combined procedures (59%). Inappropriate surgical sequencing occurred in 32 of 73 (44%) patients undergoing combined procedures. Persistent hypotension, indicating that the wrong cavity was accessed, and misleading chest tube output are the leading pitfalls in thoracoabdominal injury management.
