Filter by:Our study aims to lay the basis for a predictive modeling service for postoperative complications and prolonged hospital stay in patients suffering from psychiatric diseases undergoing colorectal surgery. Furthermore, we aim to investigate the impact of preoperative Risk factors, psychiatric and psychosomatic diseases on the outcomes of colorectal surgery and the complications after colorectal surgeries like anastomosis insufficiency via predictive modeling techniques The service mentioned above will be publicly available as a web-based application
The primary aim of this study is to compare the rate of acute urinary retention (AUR) after immediate compared to early (24-hours) removal of urinary catheter (UC) in patients undergoing minimally invasive colorectal resection. The study hypothesis is that immediate UC removal is non-inferior to 24-hours UC removal in terms of AUR rate. The secondary outcomes focus on goals that could be positively impacted by the immediate removal of the UC at the end of the surgery. In particular, the rate of urinary tract infections, perception of pain, time-to-return of bowel and physical functions, postoperative complications and postoperative length of stay will all be measured.
A drop in blood pressure during anaesthesia for a surgical procedure has been associated with worse patient outcomes, including complications such as damage to the heart, brain and kidneys. Continuous blood pressure monitoring prior to the start of anaesthesia alerts the anaesthetist to drops in blood pressure and allows this to be treated promptly. This may help to avoid the complications described above. Continuous blood pressure monitoring is carried out by inserting a small plastic tube (cannula) into an artery. In this study, the investigators propose inserting a cannula into the radial artery in the wrist before a patient is anaesthetised for surgery. The usual technique for insertion of this cannula is for the anaesthetist to identify the site of the radial artery by feeling for an arterial pulse with the fingertips (palpation). An alternative technique for identification is to use ultrasound. Ultrasound creates a two-dimensional image of the area under the skin on a screen, enabling the operator to visualise the artery being targeted. This may reduce the number of cannulation attempts required, reducing patient discomfort.
The study aims at investigate whether the oxygen partial pressure is improved in the prone position postoperative after abdominal surgery. Included are 50 adults operated with abdominal surgery. The Intervention is turning from supine to prone position and then back to supine position while measuring whether an improvement occurs in oxygen saturation and oxygen partial pressure, or not.
The Norwegian Stoma Trial is an open-label multicenter trial investigating the use of stomas, both diveriting and permanent, in the surgical treatment of rectal cancer. The objective is to compare the chosen strategy to surgical complications, health realted quality of life and length of stay.
Ultrasound-guided erector spinae plane block (ESPB) is an interfascial blockade during thoracic anesthesia, first described by Forero in 2016, and is highlighted by technically feasibility and less complication rate. The patient is placed as decubitus position. The anesthesiologists use echo to identify the ipsilateral transverse process at T5 level, and insert the needle to 2-3 cm lateral to the spinous process until contact the transverse process. Then the injected local anesthetic will penetrate via erector spinae muscle to paravertebral space to affect and relieve pain.
Hypoxia and reduced oxygen partial pressure is commonly occurring after abdominal surgery. This study aims to investigate whether similar changes also occur after orthopedic surgery in the form of upper limb surgery. Inclusion: 60 patients undergoing orthopedic surgery in the form o knee-, hip-, shoulder- or elbow surgery. Exclusion: Dementia or cognitive impairment that makes it impossible to participate in studies. Arterial blood gas and lung function are undertaken before surgery, the day after surgery and at follow-up.
The bispectral index parameter is used to guide the titration of general anesthesia, however; conflicting results between different studies cannot prove the benefit of EEG monitor on improvement of OR efficiency. Next Generation SedLine features an enhanced signal processing engine, which provides processed EEG parameters. This four channel EEG monitor for the monitoring of perioperative anesthesia depth prevent overdose of medication and may help for individualized anesthetic plan. This research intended to observe the emergence time from end of the surgical wound closure to patient awake (or to extubation) with or without SedLine.
Rationale: The rate of postoperative complications after high-risk surgery remains high despite recent advances in perioperative management. There is a lack of objective and reliable information that can be used for risk stratification and to guide treatment decisions. Objective: To describe the perioperative biomarker response in surgical patients with and without a postoperative complication and construct a preoperative and postoperative prediction model for postoperative complications. To systematically collect perioperative blood samples and clinical data in high-risk surgical patients for the development en analysis of biomarkers. Study design: Multicenter, prospective, observational study. Study population: 4819 patients undergoing elective cardiac, colorectal, vascular and lung surgery. Intervention (if applicable): Not applicable. Main study parameters/endpoints: Main study parameters are levels of PCT, CRPhs, IL-6, GDF-15, sFLT, NT-proBNP, cTNThs, CysC and NGAL. Main study endpoint is the occurrence of a major postoperative complication which is defined as a surgical site infection, pneumonia, sepsis, acute kidney injury, major adverse cardiovascular events or death within 30 days of surgery. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In each patient five blood samples will be drawn for analysis. Most of the blood samples are drawn simultaneously with routine perioperative laboratory testing, which is common in this study population. In case a patient is admitted to the Intensive Care Unit blood samples will be collected using an arterial line. There are no direct risks or benefits for patients included in the study.
Background: Revisional bariatric surgery (RBS) represents a further solution for patients who experience an inadequate response following initial bariatric surgery or significant weight regain following an initial satisfactory response. Studies including the follow-up of patients with complications after RBS are still lacking. Aim: to analyze the trend, mortality, and complications at 30 days after RBS in Italy. Secondary aim: 30-day readmission rate, reoperations for any reason related to bariatric surgery. Design: longitudinal, prospective, multicenter study. Time interval: 10 months October 2021 - July 2022). Setting: 11 high-volume bariatric centers of the Italian National Health Service (SSN), university hospitals, hospitals, accredited private centers. Methods: All patients undergoing RBS from 01.11.2021 through 31.04.2022 will be enrolled in a prospective, online database, registering indications, technique, mortality, intraoperative and perioperative complications, readmission for any reason. All participating centers follow the same preoperative work-up protocol, indications, informed consent, and postoperative follow-up, including scheduled telephone and outpatient visits after 7, 15 and 30 postoperative days. Inclusion criteria: revisional procedures; no concomitant procedure, but hiatal hernia repair; age >18<60 years; compensated comorbidities; informed consent including COVID-19 addendum; adherence to specific admission, in-hospital and follow-up protocols. Patients undergone RBS during 2016-2020 will be considered a control group. The study will not involve any modification of the usual protocols. Statistical analyze: to make qualitative quantitative comparison regarding clinical and anthropometric factors between the two study groups (2021-22; 2016-20), the z-test for two proportions and t-test (two-tailed) will be used, respectively. The significance is fixed at 0.05 and all analyzes will be performed with the SPSS v.27 software. Expected results: enroll about 500 patients to obtain information on the safety of RBS and the current trends in Italy.
