Hypertension as a Reason for Concellation of Elective Minor Abdominal Surgery
During the anesthesia outpatient consultation, patients proposed for minor abdominal surgery, known hypertensive patients are selected. On the day of the procedure, we check the blood pressure figures. If the numbers are high: SBP ≥ 180 and/or PAD≥110: we start by a filling as well as a dose of 1 …
Prevalence of Diabetes in Patients Who Are Candidates for Spine Surgery
The purpose of the study is to assess, through systematic screening, the prevalence of diabetes or prediabetes in patients who are candidates for lumbar spine surgery.
ctDNA in CRC Patients Undergoing Curative-intent Surgery for Liver Metastases
This is a prospective multicenter cohort study, was designed to explore the prognostic value of ctDNA as a biomarker of disease response and recurrence or death in patients undergoing curative-intent surgical resection of Colorectal cancer liver metastasis.
Five-Year Visual Function and Refractive Outcomes After Congenital Cataract Surgery
This prospective multicenter observational study aims to evaluate the 5-year visual function and refractive outcomes in children undergoing surgery for congenital cataract. Key outcomes include best-corrected visual acuity, stereopsis, refractive error, and axial length growth. The study will help identify long-term trends and prognostic indicators after early cataract intervention in …
Effectiveness, Stability and Influence Factors of Femtosecond Laser Assisted Cataract Surgery
What is this study about? This study looks at whether a laser procedure called femtosecond laser-assisted arcuate keratotomy (FSAK) helps people with both cataracts and mild astigmatism see more clearly after cataract surgery. Astigmatism causes blurry vision because the front of the eye (cornea) is curved unevenly. The FSAK procedure …
Frailty, Physical Capacity and Lung Function in Postoperative Cardiac Surgery Patients
The goal of this observational and prospective study is to investigate changes in physical performance, lung function, and respiratory and peripheral muscle strength in patients during the postoperative period following coronary artery bypass grafting (CABG) and valve replacement surgery..
Comparison of Different Analgesic Nerve Blocks in Total Knee Replacement Surgery
The goal of this observational study is to compare the equivalent analgesic efficacy of three regional anesthesia techniques in total knee replacement surgery. The main question it aims to answer is: • Non inferiority of each technique in relation to the others Participants will receive selective spinal anesthesia and the …
Ultrasound-Guided Microwave Ablation Vs. Surgery for Low-Risk PapilaryThyroid Carcinoma
This study aims to investigate the efficacy and prognosis of ultrasound-guided and gene-based microwave ablation (MWA) versus surgical treatment in patients with low-risk papillary thyroid carcinoma (PTC). By analyzing genetic testing results, the study explores the impact of genetic mutations on treatment selection for low-risk patients, providing more precise molecular …
Comparison of Video and Direct Laryngoscopy in Obese Patients During Surgery
This study aims to evaluate how intubation performed with two different brands of videolaryngoscope and the Macintosh laryngoscope during surgeries in obese patients requiring general anesthesia affects the VIDIAC score, hemodynamic response, and early postoperative complications. Complications such as sore throat, hoarseness, nausea, and vomiting will be recorded in the …
Trop2-targeting NIR-II Molecular Probe for Breast Cancer Precise Surgery
Positive surgical margins are closely associated with local recurrence in breast-conserving surgery (BCS). Meanwhile, accurately assessing sentinel lymph node (SLN) metastasis is crucial for determining the extent of axillary lymph node dissection (ALND) and minimizing complications. Indocyanine green (ICG)-based the second near-infrared (NIR-II) fluorescence imaging offers real-time visualization during surgery, …
