Continuous, less invasive, hemodynamic monitoring in intensive care after cardiac surgery.

A pulse-contour-based method for continuous measurement of cardiac output (CO) and systemic vascular resistance (SVR) was tested and arterial thermodilution, used for calibration, was compared to pulmonary artery thermodilution. In 30 patients CO and SVR were measured by pulse contour analysis (COpc, SVRpc) 270 times in 24 h and compared to arterial (COart, SVRart) and pulmonary arterial (COpa, SVRpa) thermodilution measurements. The mean difference between COpa and COart was 0.26 L/min (3.6%) with a standard deviation (SD) of 0.7 L/min, the correlation coefficient was 0.96, and the coefficient of variation was 5.0% and 5.9% respectively. COpc did differ from COpa by 0.11 L/min (1.5%, SD = 0.6 L/min) and from COart by 0.15 L/min (2.1%, SD = 0.7 L/min). Correlation of COpc with COpa was 0.91, correlation of COpc with COart was 0.90. SVRpc did correlate with SVRpa, a coefficient of 0.94, and with SVRart, a coefficient of 0.92. Mean COpc and SVRpc did not differ significantly from COpa or COart and SVRpa or SVRart during the 24 h study period. It is concluded that COart correlates well with COpa and can be used to calibrate COpc. COpc and SVRpc agree with thermodilution-based CO and SVR without recalibration for 24 hours.

Oral manifestations of HIV infection.

OBJECTIVE: To provide a comprehensive, literature-based guide to the diagnosis of and the management and referral of patients with oral diseases associated with human immunodeficiency virus (HIV) infection. DATA SOURCES: The literature was reviewed to identify common oral manifestations of HIV infection, the physical and laboratory findings associated with them, and the therapies used to treat them. The National Library of Medicine's AIDSLINE database was searched using the term "mouth diseases." Additional references were identified from the bibliographies of these articles and related textbooks. STUDY SELECTION: English-language abstracts were reviewed to determine each paper's clinical relevance. To be considered clinically relevant, a paper had to describe the physical appearance of oral manifestations, methods used to diagnose oral manifestations, or treatment and referral guidelines. More than 600 abstracts were identified. DATA EXTRACTION: After the abstracts were reviewed, articles were selected and were reviewed for possible inclusion. If both of two reviewers agreed that an article was clinically relevant and dealt with conditions that occurred in more than 1% of HIV-infected patients, the article was included. DATA SYNTHESIS: 16 conditions that occur in more than 1% of HIV-infected patients were identified. Information on these conditions was collected and sorted into three categories: clinical appearance, diagnostic methods, and treatment. CONCLUSIONS: Almost all patients with HIV infection will contract oral diseases. Guidelines for recognizing, diagnosing, and managing these conditions are presented. Most conditions can be treated or alleviated through the combined efforts of the physician and the dentist.
