Filter by: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.
A randomized, controlled trial to evaluate patient compliance and biologic mechanisms of a short-term pre-operative Protein-Calorie Restriction (PCR) diet in comparison to a normal ad libitum diet for 4 days before elective vascular surgery involving a major operation. This study is a step in the long-term primary scientific objective to test the hypothesis that brief up regulation of endogenous H2S via pre-operative PCR in elective major surgery improves clinical outcomes in humans. After a successful pilot study of the PCR diet conducted inpatient before carotid endarterectomy, the investigators now aim to expand the study to at home diet among a variety of vascular surgery procedures.
Neoadjuvant radio-chemotherapy (NRCT) represents a milestone in the treatment of selected rectal tumours. Ideal time interval between the end of NRCT and surgery is still debated; a 6-8 weeks time interval is considered optimal, but shorter or longer intervals have been associated with better oncological outcomes. Moreover, there is a lack of data about clinical postoperative outcomes and different time intervals after the end of NRCT. Here, effect that different time intervals have on postoperative complications with particular regard to the anastomotic dehiscence have been evaluated. Methods One hundred-sixty-seven patients underwent surgery after long-course NRCT. Three different time intervals were considered: (0-42; 43-56; >57 days).
To adequately assess postoperative pain in the coronary artery bypass surgical population a multicentered retrospective chart review was carried out; the study utilized a nonexperimental comparative descriptive study design. The retrospective review was conducted over a six-month time frame, consisting of June 2017 through November 2017, at two hospitals within the same organization. The data collection process began in late December of 2017 and January of 2018. The assessment of postop pain was performed by using a standard 11-point numeric pain rating scale on post extubation day one and the day of discharge.
Stoma surgery is a relatively common treatment for patients suffering from colorectal diseases.This study aimed to investigate the impact on hospital stay and short-term overall complications prior to and following the introduction of an outpatient preoperative stoma education program.
The aim of the study is to investigate the use of Hemopatch to prevent biliary fistula in patients submitted to surgery for malignancy.
This is a clinical and cost-effectiveness analysis within a retrospective comparative study of RDP and LDP conducted at Sanchinarro University Hospital from 2011 to 2017. Outcome parameters included surgical and post-operative costs, quality adjusted life years (QALY), and incremental cost per QALY gained or the incremental cost effectiveness ratio (ICER). A sensitivity analysis was carried out in order to propagate the uncertainty of the estimations to the results of the model. The investigators use a multivariate and stochastic sensitivity analysis performed by 5000 Monte Carlo simulations. The cost-effectiveness plane was used to represent all pairs of solutions of the model.
The proposed study will investigate the feasibility of using the Wake Forest Real-time Location System (RTLS) in monitoring patient movement during their in-hospital postoperative recovery. The study will involve patients who have undergone surgery requiring inpatient admission to the surgical ward. Actual patient movement will be monitored during their postoperative recovery and compared with data recorded by the Wake Forest location system. In this small pilot study, a subgroup of participants will be randomized to two cohorts, continuous walking and interval walking. Tolerability of the varied walking intensity will be measured.
The accuracy of devices like the recent FDA-clearance of the Omron HeartGuide™ Blood Pressure sensor in robust clinical settings remain in question and thus form the underpinning of this research study. The objective of this pilot prospective study is to assess the accuracy of the Omron Blood Pressure sensor as compared to arterial line blood pressure monitoring.
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.
