Filter by:This study evaluates the difference in results between eyes that have been treated wavefront optimized laser vision correction (either LASIK or Photorefractive Keratectomy) compared to eyes treated with topography-guided laser vision correction (either LASIK or Photorefractive Keratectomy). Each participant will receive wavefront optimized correction in one eye and topography-guided correction in the other.
To testify the prevention of Erythropoietin on cardiac surgery associated-acute kidney injury, and trying to provide evidence for protecting the renal function and improving the prognosis for patients after cardiac surgery.
The study evaluates the use of noninvasive hemoglobin with In Vivo feature and PVi monitoring using pulse-oximetry based technologies and their effect on the management of transfusion and infusion decisions and clinical outcomes for the surgical patient.
The purpose of this research is to look at how educational videos provided by doctors might affect patients knowledge, satisfaction, confidence, and anxiety with post-operative Mohs surgery care. Patients will be randomized to either: 1) a group that receives educational videos in addition to standard-of-care written and verbal instructions or 2) a group that receives only standard-of-care written and verbal instructions.
This is a prospective, single-center, cohort study in patients undergoing surgical procedures to collect data using Masimo SedLine EEG device in order to evaluate a newer version of PSI measurement against an older version of PSI measurement.
The Foley catheter is one component in a catheter insertion procedure that could contribute to a catheter associated urinary tract infection (CAUTI). Improvements in the catheter insertion procedure using the ERASE CAUTI Tray system may help to lower these infection rates.
Pelvic fractures in which integrate the acetabulum fractures represent a risk of traumatic injury to the sciatic nerve trunk by stretching or section (1): Judet and Letournel reported a complication rate of around 6% (1). Fractures of the acetabulum strictly speaking are also providers of neurological complications with rates, significant, have recently been precisely detailed by a cohort study published by Lehmann et al. (2): In a series of 2073 patients, the authors reported an overall complication rate of neurological related to the initial trauma of the order of 4%. In this series, 1395 patients were operated with a rate of iatrogenic neurological complications of 2 to 3%. Regarding the first routes (and therefore the types of fractures), the Kocher-Langenbeck path is the path that leads to the greatest number of neurological complications: 3 to 4% in this series (2). However, this cohort study does not specify what truncal achievement it is. Obviously violations posterior acetabular are preferentially providers of sciatic injury while violations prior acetabular are more providers of obturator or femoral lesions. But this is not always the case. Moreover, this study does not specify the type or severity of neurological involvement.
The purpose of this study is to evaluate the effect of pharmacogenetic (PGx) guided treatment when implemented into the pre-operative process for patients undergoing an elective spinal surgical procedure and requiring post-operative acute pain management, as compared to a group of subjects with the same attributes without the guidance of PGx testing for their post-surgery pain management. This study will also evaluate whether PGx testing can reduce narcotic consumption, opioid-related adverse effects, time to mobilization, medical visits and costs.
Cervical incompetence complicates approximately 1 in 500 pregnancies . Those women with cervical incompetence are at risk for second trimester spontaneous abortion and preterm labor. Cervical cerclage reduces these risks but must be performed under general or neuraxial anesthesia. Some anesthesiologists prefer neuraxial anesthesia, as it reduces fetal exposure to medications and avoids the risks associated with loss of maternal airway reflexes under general anesthesia. Spinal anesthesia, in particular, has the added advantage of being technically simple while still providing a rapid, dense sensory block. For cerclage placement, patients require a sensory block from the T10 to S4 dermatome in order to cover sensation from the cervix as well as the vagina and perineum. Patients presenting for cerclage under spinal anesthesia pose a dosing challenge given the physiologic changes associated with pregnancy. As women progress with their pregnancy, they require lower doses of intrathecal local anesthetic to achieve similar block level. Multiple studies have demonstrated that these changes start during the second trimester. Inadequate sensory coverage with a spinal anesthetic typically necessitates conversion to general anesthesia, causing additional time wasted and added risk to the patient and fetus. Anecdotally, this is the reason why some anesthesiologists choose general anesthesia for patients undergoing cerclage over a spinal anesthetic. As there is currently no literature determining the correct dosage for these patients, we propose a dose-response study to determine the ED90 of intrathecal lidocaine for adequate anesthesia for elective cervical cerclage placement.The findings of this study will help determine the minimum dose of intrathecal lidocaine necessary to provide adequate spinal anesthesia for cervical cerclage for 90% of women. This will help decrease the frequency of inadequate anesthesia for cervical cerclage.
This is a survey of members of the American College of Surgeons (ACS), to describe and explore current patterns of their decisions about withholding or continuation for patients taking aspirin (ASA) in the perioperative period. Secondarily, the survey will also explore surgeons' knowledge about the risks and benefits attending this decision, and about national organizations' recommendations.
