Sequential compression devices (SCD) have become the most common form of prophylaxis against the formation of deep venous thrombosis (DVT) among surgical patients. However, compliance with SCD has traditionally been poor. The aim of this study was to assess the affect of patient and nurse education by surgeons on SCD compliance. This was a prospective study involving a single teaching hospital. Compliance was checked twice daily. The main outcomes were compliance rates with SCD use before and after nurse and patient education. Nurses were not aware of the study. Surgical floors had a history of resident and attending interactions regarding SCD, whereas nonsurgical floors did not. A handout that emphasized SCD importance was also given to patients on surgical units. Before education, surgical units had a compliance rate of 61.5 per cent, whereas nonsurgical units had a 48 per cent compliance rate. This difference was significant (P = 0.014). After nursing and patient education on the busiest surgical floor, compliance rates on the surgical ward increased to 65 per cent, a difference that was not of statistical significance (P = 0.515). A nursing unit's daily experience is the most important factor in their compliance rates with SCD use. Focused nursing lectures and patient education may have incremental value.

A noninvasive tool to recognize early shock would improve outcome by providing prompt recognition of tissue ischemia and precise resuscitation endpoint. The skin is the first tissue bed to vasoconstrict in shock states. Studies have demonstrated that transcutaneous partial pressure of oxygen (PtCO2) increases with higher FiO2 in nonshock states as arterial pressure of oxygen (PaO2) increases, but in shock situations, PtCO2 mirrors changes in cardiac output and oxygen delivery with minimum response to increasing FiO2 and PaO2. This study examined the relationship of hemodynamic variables and the degree of PtCO2 response to FiO2 of 1.0 (identified as the "oxygen challenge test") to mortality and organ failure. This prospective observational study examined 38 patients requiring at least 24 h of cardiac output monitoring for shock resuscitation in the Surgical Intensive Care Unit. Patients were resuscitated to the standard protocol of blood pressure, urine output, oxygen delivery (DO2), and mixed venous O2 (SvO2). Seventy-nine percent of the patients (30/38) with a mean age of 59 +/- 21 years had septic shock or severe sepsis with a 26% mortality (10/38). Measurements included hemodynamic variables, PtCO2, and outcome (mortality and organ failure). In this study, the ability of PtCO2 value to increase by 21 mmHg on a FiO2 of 1.0, at 24 h of resuscitation, divided survivors from nonsurvivors, P <.001. The PtCO2 response to FiO2 may provide an additional noninvasive method of detecting early shock as well as a specific endpoint of resuscitation.
