Clinical Research

Synopsis: To determine whether the presence of the Navigator® display will shorten the duration of emergence/recovery from general anesthesia.

Synopsis: To investigate the efficacy and feasibility of ultrasound guidance during sacroiliac joint injections for the treatment of sacroiliitis.

Synopsis: To determine the accuracy of continuous non-invasive hemoglobin measurements in cancer patients and to determine patient and device variability from multiple measures obtained at the same time with different devices on different fingers and different subjects.

Synopsis: To assess the accuracy and precision of noninvasive CO-Oximeter monitors in patients with various co-morbidities and extremes of physiology.

Synopsis: To examine the differences in the desire for information in the perioperative period between different subsets of adults, specifically looking at differences between geriatric patients and younger adults. Geriatric patients are often faced with limitations that younger adult patients do not have and could be considered an at-risk patient population. As such, the geriatric patient population may not be as assertive in the pursuit of desired information as younger patients despite an equitable desire to understand the risks and benefits any proposed procedure. Likewise, generational differences may exist in the overall desire for information about planned interventions. Before specific interventions for improvement can be studied a clearer understanding of the desire for information across different age groups must be examined.

Synopsis: Defining specific behaviors present in successful residents in order to use those behaviors to predict which applicants to residency programs will be successful.

Synopsis: To assess the accuracy and precision of the Masimo Labs pulse hemoglobin noninvasive monitor.

Synopsis: To capture high resolution waveform data and numerical data from the three respiratory rate methods and compare respiratory rate derived from ETCO2 to respiratory rate measured by the Masimo Acoustical Respiratory Rate Monitor. Further, we will determine the number and duration of data drop outs and alarms obtained with each method of respiratory rate monitoring.

Synopsis: To test the hypothesis that monitoring the respiratory variations via the pulse oximeter to guide volume expansion has potential to decrease postoperative morbidity and length of stay in the hospital in patients undergoing routine, moderate-risk elective surgery.

Synopsis: To assess current hemodynamic management practices in patients undergoing high risk surgery.

Synopsis: To find out which behaviors impact a child’s postoperative (after surgery) pain and anxiety while in the postoperative recovery area and at home. Studies have shown that adults’ behaviors can impact a child’s pain when children get immunizations. We think that the same thing happens while in the postoperative recovery area and at home. This study will find out which behaviors impact a child’s pain while in the postoperative recovery area and at home.

Synopsis: To gather feedback on a new internet based program (WebTIPS) to prepare parents and children for children’s outpatient surgery.

Synopsis: To analyze the influence of preoperative behavioral interactions between children, parents and health care providers on children’s anxiety before surgery.

Synopsis: To find out what parents think about giving pain medication to children, and how parent’s respond to their child’s pain at home. We are also looking at how parents know when their child has pain (how does the child express pain), and if there is any difference based on culture.

Synopsis: To look at the relationship between cultural and socio-economical variables and preoperative anxiety in children before surgery. We are also looking at how gender and temperament relate to anxiety before surgery. Other research studies have shown that culture can affect the experience of pain in adults, but we don’t know how culture may affect pain and anxiety in children and their parents. It is important to understand different variables that may increase or decrease children’s anxiety before surgery because anxiety can affect the way a child recovers after surgery.

Synopsis: The purpose of this study is to describe the incidence of persistent postsurgical pain in children up to one year following surgery and to identify factors that may be related to the development of persistent postsurgical pain, including age, gender, and type of surgery.
