Since the introduction of transesophageal echocar-diography (TEE) to the operating room in the early 1980s, 1-4 its effectiveness as a clinical monitor to assist in the hemodynamic management of patients during general anesthesia and its reliability to make intraoperative diagnoses during cardiac operations has been well established. 5-26 In recognition of(More)
T here are no objective criteria for selecting the size of a double-lumen endobronchial tube (DLT) (1). An inappropriately sized DLT can cause airway trauma and interfere with oxygenation and lung separation during one-lung ventilation. The goal of this study was to determine if measurement of tracheal diameter from the preoperative chest radiograph can be(More)
OBJECTIVE Pulse contour analysis can be used to provide beat-to-beat cardiac output (CO) measurement. The current study sought to evaluate this technique by comparing its results with lithium dilution CO (LiCO) measurements. DESIGN Prospective, observational study. SETTING Surgical intensive care unit. PATIENTS Twenty-two patients after cardiac or(More)
Postoperative patient handovers are fraught with technical and communication errors and may negatively impact patient safety. We systematically reviewed the literature on handover of care from the operating room to postanesthesia or intensive care units and summarized process and communication recommendations based on these findings. From >500 papers, we(More)
The recurrence of a benign mediastinal bronchogenic cyst 20 years after partial excision precipitated potentially serious vascular and pulmonary complications. Aggressive total surgical excision should be feasible in the majority of cases. An approach via a median sternotomy offers distinct advantages in certain cases and should be considered. Computerized(More)
Double-lumen endobronchial tubes offer many advantages during thoracic operations. However, technical problems with tube placement and potentially life-threatening complications have discouraged widespread use of standard double-lumen tubes. Some of these problems may be reduced with a new polyvinyl chloride (PVC) double-lumen tube. A total of 214(More)
The utility of recombinant Toxoplasma gondii surface antigen P22 for the detection of specific T. gondii antibodies in human sera was evaluated. Polymerase chain reaction was used to produce a 438-bp fragment of the P22 gene; the fragment corresponded to the amino acids predicted to be in the processed, native antigen. The fragment was subcloned into(More)
