Filter by:The goal of this interventional study is to reduce preoperative anxiety by Virtual Reality mindfulness. Population: all adults, able to give their consent and scheduled for surgery with high preoperative anxiety defined by Amsterdam Preoperative Anxiety and Information Scale (APAIS) score > 10. The study will recruit 100 patients in one university teaching hospital. The main question it aims to answer is: may mindfulness by Virtual Reality reduce preoperative anxiety in patients particularly anxious for the surgery? Participants will be asked to undergo to a single mindfulness virtual reality session before the surgery.
Digital storytelling is the craft and art of exploring different media and software applications to communicate stories in new and powerful ways using digital media. Because new digital tools are inexpensive and widely available, digital storytelling tends to be highly personal and at the same time universal. All in all, it is a very powerful form of communication. Digital storytelling applications include short (three to five minute) films with pictures, video clips, soundtrack and narration; storytelling performances and talks supported by media slideshows or interactive presentations; and web-based applications, including streaming media, podcasts, and blogs. When looking at the literature, different approaches to using digital storytelling are seen: it is used in the education of health professionals, in academic education, for digital story development and research, and as a therapeutic care intervention. Studies on the use of digital stories in the field of health have just begun to gain popularity, and it is noteworthy that the studies in the health services literature are not yet at the desired level and prevalence. Healthcare is a unique environment to use digital storytelling intervention as a therapeutic purpose in addition to gaining knowledge in all our activities. Using digital stories; It is thought that it will provide significant benefits to parents/children and health professionals by filling the gap in the literature in order to reduce the negative emotional behaviors and anxiety of children undergoing day surgery in the preoperative period, as an informative intervention that can attract the attention of their children while having fun.
This single-center randomized sham-controlled trial will be conducted in cardiothoracic surgery department of the Yueyang Hospital of Integrated Traditional Chinese and Western Medicine in China. A total of 92 eligible participants with pulmonary nodules (size ≥ 8mm) who will undergo VATS will be randomly allocated to a TEAS group and a sham TEAS (STEAS) group in a 1:1 ratio. Daily TEAS/STEAS treatment will be performed starting on 3 days before the VATS and continued for three consecutive days, once per day. The primary outcome will be the minimal clinically important difference of generalized anxiety disorder scale score change between the day before surgery with the baseline. The secondary outcomes include serum concentrations of 5-hydroxytryptamine, norepinephrine and gamma-aminobutyric acid, intraoperative anesthetic consumption, time to postoperative chest tube removal, postoperative pain, length of postoperative hospital stay. The adverse events will be recorded for safety evaluation. All data in the study will be analyzed using the SPSS 21.0 statistical software package.
In this prospective two-arm study, the investigators will evaluate the incidence of suboptimal preoperative assessments when the participants are evaluated through a web based application (Preanestes@s) versus the traditional outpatient interview.
Rehabilitation strategies after abdominal surgery enhance recovery and improve outcome. A cornerstone of rehabilitation is respiratory physiotherapy with inspiratory muscle training to enhance pulmonary function. Prehabilitation is the process of enhancing functional capacity before surgery in order to compensate for the stress of surgery and postoperative recovery. There is growing interest in deploying pre-habilitation interventions prior to surgery. The aim of this study is to assess the impact of preoperative inspiratory muscle training on postoperative overall morbidity. The question is, whether inspiratory muscle training prior to elective abdominal surgery reduces the number of postoperative complications and their severity grade.
To observe the retinal microvascular alteration during 3 months follow-up after Implantable Collamer Lens (ICL) operation in moderate and high myopia patients using quantitative optical coherence tomography angiography (OCTA) analysis.
In this prospective and paired study, the investigators evaluate whether the preoperative information recorded through a web based questionnaire together with a virtual non face to face patient assessment based on the information recorded by the questionnaire and the electronic records of patients is of a comparable quality to that obtained with the traditional outpatient interview.
Preoperative fasting guidelines for anesthesia recommend waiting two hours after ingesting a clear liquid and six hours after ingesting a light meal. Due to the presence of pulp, orange juice is considered a light meal by current guidelines which means a patient must wait six hours before undergoing general anesthesia. This study will use ultrasound of stomach of healthy volunteers to determine if the presence of pulp actually increases the transit time for orange juice.
Background and rationale of the study: Patients undergoing non-cardiac major surgery show a perioperative cardiac risk and postoperative complications, that can be stratified based on parameters linked to patient's conditions and to surgery types. An accurate identification of this risk could offer numerous advantages for these patients, who's 30-day mortality is around 2%. The identification of the correct risk could lead to a better pre- and postoperative management, that could guarantee a better surgery outcome and a faster postoperative recovery. To this day there is no perfect method to correctly estimate this risk. Various studies show that high BNP levels are linked to cardiac events at 30 and 180 days. Further investigations identify different groups, at low, intermediate and high risk, based on BNP levels. BNP is released by ventricular myocytes in response to a wall distress, due to an increased volume, pressure or myocardial ischemia. So BNP plasma levels could be used as a prognostic and diagnostic marker, improving the cardiac risk stratification in patients undergoing surgery and a much more precise management. This study is determined to do an evaluation of the correlations between pre- and postoperative BNP levels and the incidence of cardiac events in patients undergoing major vascular surgery.
Malnutrition has long been linked to postoperative complications and adverse outcomes in a variety of surgical fields , such as increased susceptibility to infection, delayed wound healing, and increased frequency of decubitus ulcers. In particular, it is a modifiable risk factor, as evident by studies that have associated optimization of preoperative nutrition with improved surgical outcomes. Therefore, it is important to identify these patients who are at risk so that appropriate nutritional support can be implemented. A range of options for nutritional status assessment have been proposed; a comprehensive assessment may include measurements of dietary intake, clinical assessment, anthropometric measurements, and biochemical measurements of serum protein, micronutrients and metabolic parameters . Many of the signs of malnutrition, however, only manifest in extreme cases. Thus it is crucial to identify sensitive markers that can be utilized to screen for clinical as well as subclinical malnutrition patients. In orthopaedic patients, the prevalence of clinical and subclinical malnutrition has been reported to be up to 42.4%. Common markers of malnutrition that have been studied include low serum albumin as a marker of protein status, low total lymphocyte count (TLC), and excessively high or low body mass index (BMI). They have been compared against various adverse surgical outcomes, including surgical site infections (SSI), delayed wound healing, unplanned intubation and ICU admission , postoperative anemia and cardiac complications , and length of hospital stay. However, conflicting results have been reported; for example, while hypoalbuminemia (serum albumin <3.5mg/dL) have been associated with increased risk of SSI and longer than average hospital stay, its effect on wound healing is less clear - Marin et al. reported no significant predictive value of hypoalbuminemia on wound healing, yet Greene et al. reported a 5-time increase in frequency of major wound complication. The purpose of this retrospective cohort study was to identify biomarkers of malnutrition in patients undergoing elective total knee arthroplasty (TKA) that are predictive of adverse in-hospital postoperative complications, which would facilitate the identification of at risk patients for nutritional optimization before surgery. Six-hundred and twenty-six patients who underwent elective TKA between 2013 and 2017 in the Prince of Wales Hospital in Hong Kong were reviewed; the preoperative serum albumin, TLC, and BMI were compared against in-hospital postoperative complications.
