The hypothesis is that physical activity is associated with a reduced risk of complications and death after surgery. Self-reporting of physical activity is prone to be unreliable. In order to obtain a better picture of patients' physical activity, we intend to investigate the association between the average number of steps and postoperative outcomes. Many other objective measures of physical activity are costly and time-consuming to perform; for example, exercise tests, extensive sampling, and longer questionnaires. The primary research question is: Do patients with a higher degree of physical activity, measured as the average number of steps recorded on the patient's mobile phone, have a reduced risk of peri/postoperative complications and death, measured as Days At Home alive at 30 days (DAH30)? Secondary research questions include: Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, linearly linked to DAH30? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, associated with specific peri/postoperative organ impact, such as lung, heart, cerebral, infection, or kidney complications? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, also linked to long-term outcomes one year after surgery? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, solely associated with DAH30 and organ complications for specific patient groups in terms of age, comorbidities, and/or type of surgery?

While DOACs are increasing in use in the EGS patient population, the risk of bleeding and the reversal of these agents to reduce hemorrhage is still evolving. Given the paucity of data regarding the impact of DOACs in this patient population, it becomes empiric to identify bleeding patterns and outcomes in the EGS population taking DOACs. We hypothesize that patients taking a DOAC will have a higher bleeding incidence and need for an unplanned intervention secondary to hemorrhage in EGS patients undergoing an urgent or emergent operation when compared to patients taking warfarin and antiplatelets.

To assess possible risk of aspiration with pre-operative oral medications taken with "sips" of water (100ml).
NCT01937247
The main purpose of the study is to examine whether operating room (OR) efficiency will be improved by significantly decreasing non operative time. This study also aims: 1) to evaluate whether a decrease in non-operative time will result in increased surgeon and staff satisfaction, 2) to determine whether there is an increase in the complication rate during the redesigned process perioperatively and until discharge from the post anesthesia care unit, and 3) to rate patient satisfaction.
NCT03497351
SVV is clinically affected by a variety of factors, such as abdominal pressure, body position, tidal volume, type and temperature of liquid treatment, etc. There are few reports on the effects of drugs on SVV. In clinical anesthesia, surgical stimulation and stress can affect patient hemodynamic stability, used in intraoperative vascular active drug is inevitable, they shrink or dilate blood vessels, speed up or slow down the heart rate, makes the ventricular preload and corresponding changes in the SV. Now, there is a study on SVV and PPV in patients with hypertension, but there are few reports on the effect of blood pressure drugs on the changes in patients' threshold.
NCT02741895
This study will evaluate whether information on postoperative ambulation from Fitbits can improve surgeons' ability to monitor ambulation and identify patients at risk for prolonged length of stay, 30-day readmissions, and discharge to transitional care after major surgery.

To find out the effect site concentration of remifentanil for preventing QTc interval prolongation during intubation under propofol-remifentanil anesthesia in elderly patients
NCT01678066
Study hypothesis: The Cardiotronic ICON non-invasive cardiac output monitor gives accurate information when placed on a patient's Right or Left side. Summary: To simultaneously compare physiologic data collected from two non-invasive cardiac output monitors placed bilaterally on pediatric patients undergoing general anesthesia. The FDA approved Cardiotronic ICON non-invasive cardiac output monitor has been validated by the manufacturer in pediatric and adult patients with leads placed on the left side. However, sometimes the surgical site and/or patient position precludes placement of the monitor leads on the left side. In such situations it would be useful to know whether placement of the monitor's leads on a patient's right side gives accurate cardiac output data. We will prospectively collect, and compare, simultaneous physiologic data for all enrolled children using two monitors, one on the patient's right side and one on the patient's left side.
