Filter by:Despite advances in gastrointestinal endoscopy and pharmaceuticals, gastrointestinal bleeding is still a significant emergency disease with a high mortality rate of 1.9-5 per 100 people due to excessive bleeding and shock. There are several indicators using pulse rate, blood pressure, hemoglobin, etc. to select patients who require endoscopic intervention, or hospitalization, but these are inaccurate and with a high false-positive rate and low specificity at 35-40%. Therefore, tests with high diagnostic accuracy for gastrointestinal bleeding patients are required and findings specific biomarkers for gastrointestinal bleeding are of great importance.
This study aimed to clarify the safety of anticoagulant therapy after glue injection for cirrhotic variceal bleeding patients with portal vein thrombosis.
To compare the efficacy and safety of neuroendoscopic hematoma removal and standard conservative treatment for patients with spontaneous supratentorial deep intracerebral hemorrhage.
Postoperative rebleeding is a major limitation of surgical evacuation for intracerebral hemorrhage (ICH). While computed tomography (CT) is the standard of care for postoperative hematoma cavity monitoring, CT requires significant physical and financial costs. Studies have demonstrated varying degrees of efficacy when using transcranial ultrasound to measure ICH volume. Recently, synthetic implants for cranioplasty have been shown to be safe and sonolucent. This study aims to evaluate the ability of transcranial ultrasound with sonolucent cranioplasty (TUSC) to detect and quantify bleeding in postoperative ICH patients.
Caesarean delivery is inevitably associated with a higher amount of blood loss vis-à-vis primary postpartum haemorrhage, when compared to vaginal delivery. Oxytocin use in tropical developing countries for the reduction blood loss at caesarean section have been met with challenges of ineffectiveness due to poor transportation, inadequate storage and drug adulteration. Therefore, there is a need for an effective, temperature stable uterotonic with a lesser risk of adulteration. The study is aimed at evaluating the effectiveness and safety of adjunctive sublingual misoprostol in reducing intraoperative blood loss at caesarean section.
This study is conducted to compare the anti-VEGF effect and visual function in vitreous hemorrhage patients with diabetic macular edema after pars plana vitrectomy with inner limiting membrane peeling or not
This is a multicentre, active-control randomized, prospective, Phase 3 study in adult cardiac surgery patients. Approximately 500 patients will be randomized at approximately 12 hospitals.
The purpose of this study is to evaluate the impact of compliance with enhanced recovery after surgery (ERAS) program on patient reported outcomes (PROs), surgery-specific outcomes and stress response after pancreatic surgery. This prospective observational study will include all consecutive patients undergoing pancreatic surgery over a period of three years (2022 - 2025) at two sites, namely University General Hospital of Larissa and IASO Thessalias, in Greece. Patients will be prospectively enrolled after written informed consent. Data will be collected on patient characteristics, surgical and anaesthetic techniques, complications, and length of stay. Quality of life questionnaires will be administered to patients preoperatively, on the fith postoperative day, first follow-up after discharge, one month and six months after the operation. The stress response will be assessed by measuring the Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio (NLR and PLR) preoperatively, and on the first five postoperative days. Data will be collected on pancreatic surgery-specific complications such as delayed gastric emptying (DGE), post-pancreatectomy haemorrhage (PPH) and postoperative pancreatic fistula (POPF) formation. Anonymised data will be uploaded by the principal investigator on a protected excel spreadsheet for analysis.
Pars-plana vitrectomy (PPV) is the cornerstone of surgical treatment for eyes with complicated proliferative diabetic retinopathy. Anti-VEGF intravitreal injection before PPV has shown a good effect on surgical outcomes. However, many patients present with co-morbidities that contraindicate the usage of anti-VEGF in the pre-operative period. Thus, cryoapplication, an old therapeutic tool for proliferative diabetic retinopathy may be a good alternative. The investigators present herein a comparative study between peripheral retinal cryoapplication and anti-VEGF before vitrectomy for complicated proliferative diabetic retinopathy.
Postpartum hemorrhage (PPH) remains to be one of the leading causes of maternal morbidity and mortality. It has been noted that an increasing number of PPH is attributed to the increased incidence of uterine atony. Myometrial contraction is affected by the choice of anesthetic technique and medications during cesarean delivery (CD). It has been proven that exposure to oxytocin during labor results in a decrease in myometrial contractions. Dexmedetomidine is a drug which has been used in obstetric practice due to its desirable effects such as decreasing pain, reduced elevation in blood pressure and heart rate, sedation, and diminished anesthetic requirement. It has been used as an adjunct during spinal or epidural anesthesia during CD and even during general anesthesia for some obstetric surgeries. The use of dexmedetomidine has been continuously rising due to its favorable effects. Its use as an adjunct in general anesthesia for obstetrical surgeries has been shown to have promising advantages. During this pandemic, dexmedetomidine has been utilized largely as a sedative in critically ill and intubated patients. This does not exclude critically ill pregnant patients who may also need to deliver urgently. Thus, it is important to investigate its effect on uterine contractility on this particular group of patients. The investigators hypothesize that dexmedetomidine causes a dose-dependent increase in contractility of the pregnant human myometrium, both spontaneous and oxytocin-induced.
