Filter by:Excision and grafting in burn patients can lead to severe blood loss. A preliminary study conducted in Saint Joseph Saint Luc Hospital showed that the total median blood loss was 1412 mL (1). Transfused patients had a total median blood loss of 2468 mL and an average number of 4 packed red blood cells (PRBC) administered. Among the various methods that help limit blood loss, tranexamic acid, which has been proved useful in traumatology and surgery, has not been sufficiently studied in burn patients. A preliminary study in 27 burned patients showed a reduction of blood loss with tranexamic acid (2). Objective of TRANBURN study is to demonstrate that tranexamic acid help limit blood loss and reduces the use of blood products.
The intraoperative assessment of analgesia remains problematic and no analgesia monitor is used in routine practice.
During routine general anesthesia (not standardized, left to the discretion of the attending anesthesiologist), pupillary pain index was measured one minute before skin incision. Then, variations in heart rate, blood pressure and bispectral index during the three minutes following skin incision were recorded, as well as the occurrence of movements.
The purpose of this study is to determine whether the rate of post-operative trachomatous trichiasis differs significantly between bilamellar tarsal rotation surgery with an incision height of 3 mm, bilamellar tarsal rotation surgery with an incision height of 5 mm, and Trabut surgery.
Low-tidal volume ventilation is arising as a tool to optimize the ventilatory management and to improve clinical outcome in patients undergoing general anesthesia for abdominal surgery. A recent large randomized controlled trial failed to detect a significant difference between two different approaches for ensuring adequate lung recruitment (PEEP=12 cmH2O + scheduled recruiting maneuvers vs. PEEP 2 cmH2O) during protective ventilation. Thus, in patients undergoing open abdominal surgery and receiving low-tidal volumes, the effects of different positive end-expiratory pressure (PEEP) levels and recruiting maneuvers remain to be established. Design: prospective, cross-over, physiological trial. PURPOSE To assess the physiological effects of different PEEP levels with or without scheduled recruiting maneuvers in patients undergoing general anesthesia for open abdominal surgery and receiving low-tidal volume ventilation.
1. Determine preoperative and postoperative levels of anxiety for pediatric patients ages 6-17 related to outpatient surgical intervention using the validated Psychosocial Risk Assessment in Pediatrics (PRAP) assessment tool, the State-Trait Anxiety Inventory for Adults(STAI-AD), and the State-Trait Anxiety Inventory for Children (STAI-CH) 2. Determine preoperative and postoperative levels of anxiety for parent/guardian of pediatric patients ages 6 - 17 related to outpatient surgical intervention using the validate PsychosocialRisk Assessment in Pediatrics (PRAP) assessment tool and the State-Trait Anxiety Inventory for Adults (STAI-AD). 3. Assess if additional Child Life intervention offered pre-operatively to one group demonstrates differences in PRAP scores compared to control group
The primary aim of this study is to establish if it is possible for patients who have undergone major body surgery to complete a home based exercise training program and complete the assessments required to measure physical and cognitive function. If the investigators can establish that it is feasible to complete the training and test's then further research can follow using these methods to determine whether it is possible to improve the physical function of older patients undergoing major abdominal surgery in the period following surgery by using a simple exercise regimen that can be carried out at home. By targeting physical function in this way the investigators hope to determine if it is a method for improving frailty and well being. In turn it may also have a positive impact on health service provision.
Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth breaks off at the gum line, or when a crown or filling falls out of a tooth and there is decay underneath. To place a crown, the dentist needs to expose more of the tooth. This is done by removing some gum tissue or bone. After surgery, the area will heal in about three months. Then, making a crown can begin. This healing period often delays the delivery a final crown. This study is investing a way to make the final impression at the surgery to expedite the delivery of a final crown.
In line with improvements in oncologic outcome for patients with esophageal cancer, the attritional impact of curative treatment with respect to functional status and health-related quality of life (HR-QL) in survivorship is increasingly an important focus. Functional recovery after surgery for esophageal cancer is commonly confounded by anorexia and early satiety, which may reduce oral nutrient intake with consequent malnutrition and weight loss. One in three disease-free patients has more than fifteen percent body weight loss at three years after esophagectomy. The ESPEN Special Interest Group on cachexia-anorexia in chronic wasting diseases has defined sarcopenia as skeletal muscle index (SMI) of ≤39 cm2/m2 for women and ≤55cm2/m2 for men, while similar cut-off points have been validated in upper gastrointestinal and respiratory malignancies (less than 38.5 cm2/m2 for women and 52.4 cm2/m2 for men). The European Working Group on Sarcopenia in Older People (EWGSOP) additionally recommends that assessment should also include determination of muscle function, for example gait speed or grip strength, where possible. The presence of sarcopenia is associated with increase treatment-associated morbidity, impaired HR-QL, reduced physical and role functioning, and increased pain scores in older adults. In addition, a previous longitudinal study demonstrated that the decline in HR-QL over a six year period in older adults was accelerated in the presence of sarcopenia. As such, sarcopenia may represent a modifiable barrier to recovery and subsequent retention of HR-QL and functional status, and may reinforce a persistent illness identity, among patients following potentially curative treatment for esophageal cancer.
The aim is to map the inflammatory response after surgery and further investigate the mechanisms by which inflammation is regulated. The inflammatory cascade is pivotal in protecting organisms against invading pathogens and in enabling healing of damaged tissues, yet the cascade itself may be harmful to the organism when excessive (e g septic chock). The increased immune-reactivity after trauma, such as surgery, is furthermore associated with post-operative declines in memory and learning capacity, a condition likely related to the notion of "sickness behavior". The effects on the brain after surgery and the associated neuro-immune crosstalk will now be investigated with focus on changes in immune reactivity in peripheral blood after surgery.
