Filter by:The study intends to measure the evolution over time of the cognitive capacity of patients undergoing cataract surgery in relation to the opaque lens removal surgery (cataract) in a population considered to be at risk of neurocognitive degeneration. Secondary objectives: • Estimate the incidence of postoperative cognitive dysfunctions and any episodes of perioperative delirium with the aim of demonstrating the safety of cataract surgery in the elderly patient in terms of cognitive functions and impact on the psychological state. In the context of the study a risk sub-population analysis will be carried out, evaluating the trend over time of the "endothelial cells count" parameter The elderly population remains, due to the aging of the cornea, a population "at risk" for significant alterations from the clinical point of view. During the study the endothelial cells count will be monitored, in order to be able to evaluate the safety of the cataract surgery and to be able to correctly correlate a possible deterioration in the visual acuity of patients with corneal decompensation. To evaluate the progress of the endothelial cells count in the elderly patient during the pre-intervention and post-intervention period. Since the low values of cellular media in endothelial microscopy are an element that increases the risk of complications during cataract surgery, the study wants to assess how waiting times between filter visits and cataract surgery can cause an elderly patient worsening of this parameter even in a few months. The trend of the same parameter will be monitored even after the intervention since in case of decrease, the low endothelial count could cause an alteration of visual acuity and therefore a minor improvement in cognitive performance. The research will be set as a longitudinal observational study where will be compared in each patient the parameters analyzed in the 6 months prior to cataract surgery and in the 3 months following the operation itself. Patients will be enrolled during the first cataract filter visit, will be submitted to simple questions and their clinical data will be collected. Subsequently, before and after three months of surgery repeated cognitive testing and the control normally performed instrumental tests during follow-up. A clinical follow-up will be provided, during normal follow-up visits at 20 days and 6 months after the patient's surgery: the following information will be collected during these visits - BCVA (visual acuity) - endothelial cells microscopy - OCT macula and optic nerve - Catquest 9SF; - Barthel Index; - Six Item Cognitive Test - Confusion Assessment Method (CAM): this exam will be performed within 24 hours of post-surgery and 20 days after surgery. It is important to underline that the cognitive tests proposed to patients consist of simple questions that do not depend on the visual ability of the subject.
In this study, we aim to analyse the effect of phosphate supplementation on donors undergoing partial hepatectomy for LDLT. In Group A, we are going to supplement phosphate in donors postoperatively from day 1 to day 5. We will analyse the trend of serum phosphate levels in donors postoperatively, its correlation with occurrence of postoperative complications and status of liver regeneration by CT volumetry on Day 7. Group B will constitute the controls for the study and hence attempt to find out the effect of phosphate supplementation in all donors postoperatively. We will analyse the data and elucidate the value of phosphate supplementation in reducing the occurrence of complications and effect on liver regeneration in donors in LDLT.
With population aging and limited resources, strategies to improve outcomes after surgery are ever more important. There is a limited understanding of what ranges of hemodynamic variables under anesthesia are associated with better outcomes. This retrospective cohort study will analyze how hemodynamic variables during surgeries predict mortality, morbidity, Intensive Care Unit admission, length of hospital stay, and hospital readmission. The use of machine learning in a large, broad surgery population dataset could detect new relationships and strategies that may inform current practice, and generate ideas for future research.
This study evaluates the efficacy and safety of a single session of positive expiratory pressure and of breath stacking technique in patients after cardiac surgery. The same patients will receive the two interventions, with an interval of 24 hours, and the acute effect of each will be verifed.
In this study we aimed to define a new modified SAS is to predict the incidence of postoperative complication and mortality in major abdominal and orthopedic surgery. We also identify the effectivity of this modified scoring system composed of the duration of operation in addition to the three intraoperative parameters of SAS.
The incidence of childhood obesity is at epidemic levels and increasing in the UK. Obese adults are considered a high-risk group of patients for general anaesthesia with published national guidelines on the best practice management. The proportion of children presenting for a procedure under general anaesthesia in the UK who are overweight or obese is currently unknown. Obese children are perceived to be at greater risk of complications from general anaesthesia. Previous non-UK studies suggest they take longer to recover from anaesthesia, require more medications to combat nausea and vomiting and are at greater risk of complications that may threaten their airway and breathing. This study involves reviewing the anaesthetic care record and patient notes to collect information relating to general anaesthesia and basic demographic data in children aged 2-16 years presenting for a procedure under general anaesthesia. The aims of this study are to establish the prevalence of obesity in the paediatric surgical population (i.e. the proportion of children attending UK hospitals for procedures under general anaesthesia who are overweight or obese) and to ascertain whether obese children are at increased risk compared to their healthy weight counterparts. This information will be used with the goal of reducing avoidable harm both at national and local level in the future.
The aim of the study is to evaluate the influence of CGF application into post-operative soft tissue and bone defects on post-operative complications and wound healing.
A Quality Study in the use of Post-Anaesthesia Care Unit(PACU) in Hip and Knee Arthroplasty, and the ability to bypass this unit. The investigators wish to investigate the amount of patients who is required to be secondary admitted to the PACU, after primary discharge from the operating room to the surgical ward, thereby bypassing the PACU.
Treatment for people with cancer of the lung or the oesophagus (food-pipe) often involves surgery. This surgery is complex and there is a high risk that patients will develop severe complications afterwards, leading to a longer hospital stay and higher hospital costs, and impacting greatly on recovery and quality of life. If patients' lungs and heart can be optimised before surgery, then recovery may be improved. While fitness can be improved by exercise, the lead-in time to surgery following a cancer diagnosis is often very short, and research is needed to examine what types of exercise might be most effective at increasing fitness over a short period. This project will investigate if high intensity interval training (HIIT) can increase fitness levels in people scheduled for surgery for cancer of the oesophagus or the lungs. HIIT alternates between periods of high intensity exercise, cycling on a stationary bike, followed by a period of more relaxed exercise. This approach is known to improve fitness but has not previously been investigated in patients awaiting complex cancer surgery. Groups will be compared for changes in pre-surgery fitness levels, any complications they may experience after surgery, general physical recovery after surgery and the cost of care after surgery. The investigators anticipate that patients who undergo HIIT before surgery will have less complications and better recovery after surgery, a significantly improved quality of life, and lower costs of care.
