Before having an operation doctors use expressions such as high risk, or low risk to describe the chance of complications occurring. Complications include things such as strokes and heart attacks and even death. It is thought that using words like this, instead of percentages makes it easier for patients to understand their level of risk. It is also often hard for a doctor to give a patient an exact percentage. It is important that patients have a good understanding about their level of risk associated with an operation so they can make informed decisions about whether to go ahead with it. This is an important part of taking consent before an operation. The aim of this study is to assess whether using expressions such as high risk and low risk to communicate the chance of a complication occurring during an operation is useful. Different patients may assign different meanings to these expressions. If it is found that patients interpret these expressions differently from how the doctor intended it would suggest that the way doctors communicate risk to patients should be reviewed. Patients will be asked if they are willing to participate in the study and after giving consent they will complete a questionnaire. The questionnaire will list various expressions used by doctors to describe the chance of a complication occurring during an operation, such as high risk and low risk. Each participant will be asked to give a percentage for each of the expressions. The questionnaire will be completed by patients who are waiting to have an operation at the Royal Hallamshire Hospital.
Post operative atrial fibrillation following coronary surgery (POAF) is a common complication that can affect 10-50% of patients. Intravenous magnesium, administered per-or post-operatively, reduces the incidence of POAF. However, the effect of preoperative magnesium loading on the incidence of POAF is not yet studied. 200 patients admitted for elective coronary surgery under Cardiopulmonary bypass will be included in this prospective randomized controlled trial. Treatment group will receive preoperative oral magnesium and control group will receive placebo for 3 days before the planned coronary artery surgery. The occurrence of POAF will be studied as a main outcome.
Surgery for digestive cancers is managed according to quality standards, validated by the scientific community. Despite the diffusion of these standards through the benchmarks of good practice, the results of the surgery remain disparate. In many countries, this "inequality of opportunity" has justified the establishment of quality assurance systems to measure the results of surgery for one or more localizations of digestive cancer. These surgical audit experiments have shown a positive, rapid and cost-effective impact on complication rates, recurrence rates and overall survival even in the absence of interventional measures. The data collected also helped to improve the management of subgroups of patients usually excluded from clinical trials. In Morocco, the National Cancer Prevention and Control Plan provides for the establishment of a quality assurance system with the introduction of a system for monitoring and evaluating the care of patients. This pilot project is part of this framework, for the group of patients who are candidates for surgery for digestive cancers.
Portal flow pulsatility detected by Doppler ultrasound is an echographic marker of cardiogenic portal hypertension from right ventricular failure and is associated with adverse outcomes based on previous studies performed at the Montreal Heart Institute. This multicenter prospective cohort study aims to determine if portal flow pulsatility after cardiopulmonary bypass separation is associated with a longer requirement of life support after cardiac surgery.
To document levels of cardiac troponin hsTnT in patients above 75y undergoing high risk surgery and the relationship between elevated levels and outcome in terms of hospital stay and 30 day mortality.
Bowel cancer is the second most common cause of cancer-related death in the UK, with 50,000 new cases and over 15,000 deaths annually. Surgery is the mainstay of treatment and the most common complications are an infection of the wound or lungs. These can lengthen hospital stay, reduce the quality of life, and even increase the risk of death. Bowel cancer patients are often malnourished. Optimising nutrition with supplements such as fish-oils can improve the immune response of patients, helping prevent such complications, shorten hospital stay, improve quality of life and overall survival.
Implementation of a standardized handover checklist for intraoperative anesthesia care transition attenuates burnout among anesthesiologists and improves postoperative outcomes of patients undergoing major surgery , both of which benefit the quality of patient care and the development of anesthesiology.
Prospective controlled study (Canadian Task Force II-2) : Comparison analysis regarding surgical outcomes, complications, overall survival (OS), disease free survival (DFS) and cancer specific survival between patients subjected to radical Hysterectomy either by open radical hysterectomy (ORH) or minimally invasive surgery (MIS): laparoscopic (LRH) or robotically assisted radical hysterectomy (RRH).
Patients undergoing routine surgery in the Department of Dermatology for any indication on non-scalp skin and closed in linear fashion with scar greater than or equal to 4.5cm in length will be invited to participate in this split scar, head to head study comparing zinc oxide and petrolatum. Patients will apply respective ointments to each half of scar daily for one month and maintain a log of these activities. They will be seen at 1 week, 4 weeks, 8 weeks, and 6 months post-operatively for photographic scar assessment and to complete the patient portion of the Patient and Observer Scar Assessment Scale (POSAS), a quantitative objective assessment of scar appearance. Trained observers (board-certified dermatologists) will score the observer portion of the scale. POSAS outcomes, post-operative infections, linear density of epidermal seal will be assessed at the 1 week, 4 weeks, 8 weeks, and 6 months post-operative periods and compared between the two groups. Participants will have parking validated for all visits and upon completion of all portions of the study will receive a standardized skin care gift bag containing samples for hypoallergenic skin care products (washes, moisturizers, etc.).
