Filter by:Esophageal Doppler Monitoring (Deltex CardioQ Esophageal Doppler Monitor, ODM) is used to manage patients' fluid therapy by non-invasively measuring continuous cardiac output with an esophageal probe. The aim of this study was to compare the effects of patient position changes on cardiac indices and vital signs in patients who underwent major abdominal cancer surgery with laparoscopic and open surgery using ODM.
The goal of this observational pilot study is to evaluate the feasibility and accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. The main research question is: Could tracked ultrasound be applied as an alternative to standard CBCT scanning in surgical navigation? Participants will undergo tracked ultrasound measurements of the pelvic bone on the operating room after patient anesthesia and before surgical incision.
Epidural analgesia is considered by many to be the reference standard which has been shown to reduce the intraoperative surgical stress response. However, besides its excellent analgesic effect, there are some disadvantages associated with epidural analgesia. This includes the risk of epidural hematoma/abscess ,failure rates hypotension, urinary retention. Also the need for preoperative placement in awake patients, who seem to dislike and sometimes even refuse. It is contra-indicated in the presence of coagulopathy or local sepsis. ESPB is a faster procedure that carries a lower risk of hypotension, can be used in patients with coagulopathy, easy to perform, and requires less training. So this study is to compare the postoperative analgesic effect of continous bupivacaine infusion via thoracic epidural versus erector spinae catheters following upper abdominal cancer surgery.
This a clinical trial that evaluates the efficacy and safety of three different doses of morphine, namely 1.5 mg, 3 mg and 4.5 mg, via the epidural route regarding reducing pain in elderly patients after a cancer surgery in the lower abdomen
60 Patients will be randomly assigned using computer generated randomization program (http://www.randomizer.org) into two groups, First group (Control group ,Group of continous epidural infusion [CEI]), where patients will receive continuous epidural infusion of L-bupivacaine 0.125 % at a rate of .1 ml/kg/h during the first 48 hours after surgery. Second group (Group of continous preperitoneal infusion [CPI]), where patients will receive continuous pre-peritoneal wound infusion with L-bupivacaine 0.25% at 10 ml/h during the first 48 hours after surgery.
The purpose of the proposed study is to measure surgical recovery, including the length of hospital stay, incidence of perioperative complications, and mortality at 90 days post-surgery, in surgical patients with abdominal cancer. The investigators hypothesize that this prehabilitation program will improve recovery and reduce perioperative complications via the proposed prehabilitation intervention.
To determine the yield of tissue biopsy specimen and the diagnostic accuracy of tissue acquisition using a newly developed 22 gauge needle in patients with solid lesions throughout the GI tract.
The aim of the present study is to access the success rate of ultrasound-guided thoracic epidural catheter insertion, using fluoroscopy.
The aim is to conduct a single centre retrospective study of all patients with stage IV melanoma that underwent surgery for metastases at Sahlgrenska University Hospital between 2010-01-01 and 2018-12-31. Pre- and postoperative data will be collected from digital medical records, the Swedish Cancer Registry, the Swedish Cause of Death Register as well as from the national Swedish cancer patient database (INCA). If needed, patient records will be collected from other hospitals. Results will be presented in written format as a summary and analysis of the characteristics of the cases operated on during the inclusion period. The aim is to identify predictive and prognostic factors for outcome and complications in the surgical treatment of stage IV metastatic melanoma.
The purpose of this study is to compare the results of combining two anesthetic medications (dexmedetomidine and propofol) in low doses with a standard dose of a single drug that is commonly used to provide sedation/anesthesia for MRI studies in young children (propofol). The drugs used for the MRI scan in this study will be chosen randomly. Half the patients will receive small doses of propofol and dexmedetomidine. The other half will receive propofol administered constantly throughout the scan. Other drugs that may be used include sevoflurane and nitrous oxide at the start of the sedation (for placing an intravenous), lidocaine (to reduce the pain of propofol injection) and glycopyrrolate (to prevent the heart rate from decreasing too low. The investigators will record 5 additional blood pressures and heart rates. If additional medications are required to complete the scan, the investigators will administer whatever is necessary. At the end of the study, the investigators will have an observer record the time it takes for participants to spontaneously open eyes , to be able to drink liquids and/or eat and to behave as before the study. Also, it is very important that the investigators find out from participants about changes in behavior, or if eating or sleeping habits were unusual following completion of the study. For that reason, the investigators will call participants in a day or so following the MRI scan. The investigators expect to recruit 40 children between the ages of 12 and 72 months for the study and hope to have the study completed in December 2018.
