Filter by:The hypothesis is that physical activity is associated with a reduced risk of complications and death after surgery. Self-reporting of physical activity is prone to be unreliable. In order to obtain a better picture of patients' physical activity, we intend to investigate the association between the average number of steps and postoperative outcomes. Many other objective measures of physical activity are costly and time-consuming to perform; for example, exercise tests, extensive sampling, and longer questionnaires. The primary research question is: Do patients with a higher degree of physical activity, measured as the average number of steps recorded on the patient's mobile phone, have a reduced risk of peri/postoperative complications and death, measured as Days At Home alive at 30 days (DAH30)? Secondary research questions include: Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, linearly linked to DAH30? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, associated with specific peri/postoperative organ impact, such as lung, heart, cerebral, infection, or kidney complications? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, also linked to long-term outcomes one year after surgery? Is physical activity, measured as the average number of steps recorded on the patient's mobile phone, solely associated with DAH30 and organ complications for specific patient groups in terms of age, comorbidities, and/or type of surgery?
The aim of this study is to determine the effect of using reflective blankets, which is a passive insulation product, on preventing UPH in patients scheduled for abdominal surgery under general anesthesia. It will also be evaluated whether the reflective blanket has an effect on the patients' thermal comfort and shivering levels. Inconsistent results have been reported in studies using reflective blankets. This inconsistency may be due to the fact that it was used at different stages of the perioperative process or that the body was not adequately isolated. In this study, we aimed to use the reflective blanket throughout the perioperative process and to isolate the patient's body as much as possible. Reflective blankets are inexpensive, practical to use and easy to store. With the positive results that can be obtained from this study, it can be used not only in operating rooms, but also in intensive care or other services where hypothermia is likely to occur. Within the scope of the study, a Reference group (warm air blower device), an Intervention group (reflective blanket) and a Control group (routine hospital procedure) will be established. The study was planned to be conducted with a total of 102 patients, with 34 patients in each group. In this study; patients' vital signs, coagulation tests, thermal comfort and shivering levels will be evaluated. Patients in the Reference and Intervention group will be warmed before the surgery (15 minutes), during the surgery, and until they are transferred from the post-anaesthetic care unit to the clinic. No heating process will be applied to the control group by the researcher. All patients transferred to the clinic will undergo the routine care procedure of the hospital.
This is a small-scale pre-clinical exploratory study to investigate the safety of a novel single-port robotic system for general surgery.
After review literature, Siriraj hospital has not unanimous protocol to guide proper preoperative anemia and blood transfusion. This retrospective study will review non-cardiac surgery cases and collect data such as demographic data, surgical procedures, anesthetic techniques, preoperative hemoglobin level, intraoperative estimate blood loss, blood transfusion, and post operative complication in Siriraj hospital which has many patients undergo various operations. This study can be model to develop preoperative anemia management guideline in Siriraj Preanesthesia Assessment Center (SIPAC), Siriraj hospital and reduce risk and adverse outcomes after blood transfusion in the future.
Preoperative antimicrobial prophylaxis is a key element for the prevention of surgical site infection, the most common type of nosocomial infection in surgical patients. Prophylactic antibiotics are selected depending on the type of surgery, and first- or second-generation cephalosporins have been mainly used. Cefoxitin, a second-generation cephalosporin with anaerobic activity, has been used in various clinical settings as a prophylactic antibiotic for colorectal surgery. Cefoxitin is generally dissolved in normal saline and intravenously administered for a short time of 5-10 minutes before skin incision. However, there are several drawbacks to the current dosing strategy. First, the dose of cefazolin is determined by a "rule of thumb", and there is controversy over whether 1 g or 2 g is appropriate, with the opinion that 2 g being more appropriate prevailing. Second, the standard administration method unnecessarily induces a concentration higher than the concentration required to prevent surgical site infection. Third, significant covariates that can affect the maintenance of MIC during surgery are not considered. The target-concentration controlled infusion (TCI) method can be a viable alternative administration method for antibiotics. The TCI method enables individual customized administration according to the covariates (i.e., weight, creatinine clearance) included in the pharmacokinetic parameters; also, although with some variability, the drug can be administered while maintaining the target concentration. The aim of this study was to evaluate the effectiveness of administering cefoxitin in patients undergoing colorectal surgery with a syringe pump equipped with a target concentration control injection function
The treatments will be: 1) norepinephrine or phenylephrine infusion to maintain intraoperative MAP ≥85 mmHg, delayed resumption of chronic antihypertensive medications, and a target ward MAP ≥80 mmHg (tight pressure management); or, 2) routine intraoperative blood pressure management and prompt resumption of chronic antihypertensive medications (routine pressure management).
Experimental studies have shown that inhalational anesthetics may be neurotoxic by for example causing amyloid beta deposition. Otherwise a pre-clinical study reported an increase in tau phosphorylation with the use of propofol. Whether anesthesia and surgery contribute to the development of long-term cognitive decline remains however controversial. A meta-analysis concluded that general anesthesia could increase the risk of postoperative cognitive decline (POCD) compared with regional or combined anesthesia but this was not shown for Postoperative delirium (POD). This conclusion should be interpreted with caution as these studies showed many shortcomings. Currently no study has compared the release of Neurofilament Light, a biomarker of neuronal injury, in patients undergoing surgery under general anesthesia compared to surgery with Hypno-analgesia and thus without anesthetic drugs.
Since December 2019, when the novel coronavirus disease (Covid-19) spread throughout the world, data have been needed on the effects of the pandemic on various aspects of healthcare systems. Recommendations for social distancing and quarantine decrees made by local governments, alongside the general public fear from the spread of the virus, are presumed to have markedly affected the trends in hospitals visits. Understanding the exact nature of the effect is critical for better anticipating and preparing health systems in the event of future outbreaks and in the post outbreak period. Therefore we intend to To identify retrospectively all patients who presented to the emergency department at our medical institute between January 1 - March 31 in the following years: 2017, 2018, 2019, 2020. We will examine the impact of COVID-19 on the rates of surgical emergency visits, ratio of surgical visits to non-surgical visits, the ratio of severe presentations to non-severe presentations, and the impact of age on ED attendance.
This study is designed to help decide how much intravenous (IV) fluid should be given to pediatric trauma patients. No standard currently exists for managing fluids in critically ill pediatric trauma patients, and many fluid strategies are now in practice. For decades, trauma patients got high volumes of IV fluid. Recent studies in adults show that patients actually do better by giving less fluid. The investigators do not know if this is true in children and this study is designed to answer that question and provide guidelines for IV fluid management in children after trauma.
Patients with suspected or proven sigmoid colon adenocarcinoma, eligible for curative treatment whose MRI can be reviewed prior to surgery and has no decision regarding radical treatment are eligible. Patient are randomised to the control arm which the standard care of preoperative CT imaging and subsequent discussion by the Multidisciplinary Team or the interventional arm which has the additional use of MRI imaging and subsequent discussion by the Multidisciplinary Team. Patients are followed up at 1 and 3 years together with QoL questionnaires.
