NCT ID: NCT05975398 Recruiting - Complications Clinical Trials

China Research for Severe Spontaneous Intracerebral Hemorrhage(CRISIH)

Start date: July 1, 2022
Phase:
Study type: Observational [Patient Registry]

Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSICH patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Study Design: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Objective: In this study, investigators will estimate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.

Cost Effectiveness of Various Implant Placement Protocols in the Esthetic Zone

Start date: January 1, 2026
Phase: Phase 4
Study type: Interventional

Loss of teeth in the anterior upper jaw significantly affects both well-being and chewing function. Nowadays, dental implants are the treatment of choice for replacing missing teeth with fixed dental prostheses and are often placed in the anterior upper jaw. Depending on various patient-related factors, protocols for the placement of dental implants involve the following time points after tooth extraction: 1. On the same day (immediate implantation) 2. After 1-4 months (early implantation) 3. After more than 4 months (late implantation). The different treatment protocols have been investigated over long periods. The choice of the individually suitable treatment protocol for dental implantation depends on many factors and is of utmost importance in order to achieve the best possible treatment outcomes. Selecting an inappropriate treatment protocol would otherwise result in an increased risk of failure. After decades of research and development in dental implantology, an expert association (International Team for Implantology, ITI) published an evidence-based decision management tool in 2022. This decision management tool assists dentists in choosing the individually suitable implant treatment protocol for single-tooth replacement in the upper jaw. A structured examination of the tooth to be extracted allows to classify the situation and select the most suitable treatment protocol for the individual situation. The treatment protocols differ in terms of time and material requirements, which are associated with different costs. There is limited data about the cost-effectiveness of these treatment protocols. The present study aims to assess how the costs of the three treatment protocols differ in relation to treatment success.

NCT ID: NCT05035537 Recruiting - Kidney Transplant Clinical Trials

PGDT in Patients Undergoing Kidney Transplant

PGDT
Start date: January 1, 2018
Phase: N/A
Study type: Interventional

This study is a multicentric randomized controlled trial comparing two groups of patients undergoing single or dual kidney transplantation from deceased donors. To reduce perioperative complications optimal fluid management is essential in patients undergoing kidney transplantation. Heart rate, Medium Arterial Pressure (MAP), Central Venous Pressure (CVP), and urine output have been proposed in the literature to guide perioperative fluid therapy. These criteria are routinely applied in clinical practice; however these criteria have shown low sensitivity and poor predictive of postoperative complication, especially if used alone. The traditional approach in renal transplantation is the volume infusion guided whit CVP to the point of no further fluid responsiveness, but this can lead to excess fluid which can damage the endothelial glycocalyx and lead to organ failure for a fluid shift into the interstitial space. As a way to reduce postoperative complications in surgical patients, in recent years, several studies have examined Perioperative Goal Directed Therapy (PGDT) as fluid administration guided by optimization of preload with the use of algorithms based on fluids, inotropes and/or vasopressors to achieve a certain goal in stroke volume (SV), cardiac index (CI), or oxygen delivery (DO2). However results regarding the potential role of PGDT cannot be considered definitive, because the various studies on the subject have not all conformed to the same methods and have not uniformly applied the same measurements, so their results regarding the potential role of PGDT cannot be considered definitive. The aim of this work is to compare the effects of PGDT with conventional fluid therapy in patients undergoing kidney transplantation achievable through implementation of the non invasive monitoring.

NCT ID: NCT04814966 Completed - Clinical trials for Postoperative Complications

Feasibility of Extended Non-invasive Haemodynamic Monitoring in the PACU

Start date: April 1, 2019
Phase:
Study type: Observational

Post-operative monitoring of all patients after anaesthesia in the post anaesthesia care unit (PACU) is standard of care today. It helps to reduce morbidity and even mortality in high-risk patients. In addition to clinical monitoring by qualified personnel, this monitoring also includes, commonly non-invasive, intermittent, haemodynamic monitoring. This monitoring is also used to evaluate the transferability of patients from the PACU to the ward. The aim of our study is to perform extended monitoring of volume status and haemodynamics with non-invasive monitoring methods such as transthoracic echocardiography and the volume clamp method in the recovery room.

NCT ID: NCT04756050 Completed - Nerve Block Clinical Trials

Comparison of Different Approaches for Supraclavicular Block and Their Effects on Diaphragm Muscle Function

Start date: February 16, 2021
Phase: Phase 4
Study type: Interventional

Brachial plexus blocks used for anesthesia in upper extremity operations can be performed with interscalene, axillary, supraclavicular and infraclavicular approaches. Plexus blockage can be performed under the guidance of needle nerve stimulation, artery palpation or ultrasonography (USG). Nowadays, the simultaneous use of USG during the block allows the protection of structures such as nerves, pleura and vessels, and allows practitioners to see the needle and the spread of local anesthetic during the injection. Although supraclavicular block seems to be advantageous because the brachial plexus is more compact and superficial in this region, it has a disadvantage of being close to the pleura. (Increased risk of pneumothorax) With the use of USG, this risk has decreased and the supraclavicular block has become an alternative to infraclavicular block, which is widely used in upper extremity surgery. Due to the compact structure of the brachial plexus trunk at the first rib level, the application of the block is easier and the block formation is faster due to the peripheral spread of the local anesthetic. With the spread of local anesthetic to C3-C5 nerve roots in the brachial plexus, paralysis can be seen in the ipsilateral phrenic nerve up to 67%. Patients who will be operated on, especially in patients with respiratory distress, may experience respiratory distress due to the dysfunction of that side diaphragm muscle. With the help of ultrasound, the inspiratory and end-expiratory thickness of the diaphragm is measured with the Diaphragm Thickness Index (DTI), which is a new and effective method used as a mechanical ventilator weaning index in intensive care units. With this method, we can examine the effect of phrenic nerve block on diaphragm muscle due to local anesthesia in the acute period. DTI is calculated as a percentage from the following formula: (Max thickness at the end of inspiration - Max thickness at the end of the expiration) / Max thickness at the end of the expiration. By comparing 3 different approaches used in supraclavicular block, we aimed to investigate the most appropriate block approach in terms of effectiveness, speed, complication rate, effects on diaphragm and 6 months effects.
