NCT ID: NCT03500809 Not yet recruiting - Clinical trials for Post-Op Complication

Aqueous Release to Treat IOP Spikes Post-cataract Surgery

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

Intraocular pressure (IOP) rise after cataract surgery is an important and common problem. Over 300,000 cataract operations are done per year in the United Kingdom alone. IOP rise can adversely affect vision and can be particularly detrimental in glaucoma patients with pre-existing visual field defects. The aim of this study is to evaluate the efficacy and safety of aqueous humor release (also known as burping of the wound), a procedure that has been used for decades to quickly reduce acute IOP spikes following cataract surgery. Currently there is no published evidence on a standard technique to perform wound burping. Similarly there is uncertainty around the amount and duration of the IOP decrease, and the type and frequency of complications eventually associated. This will be the first research project formally evaluating this procedure. This study will also help allay issues over fluid release in high IOPs and consequences of such dramatic IOP drop which concerns ophthalmologists who do not routinely use this technique.

NCT ID: NCT03440268 Not yet recruiting - Acute Kidney Injury Clinical Trials

Prevention of Acute Kidney Injury by N-Acetylcystein in Patients Undergone Cardiac Valve Replacement

Start date: March 15, 2018
Phase: Phase 4
Study type: Interventional

This is a randomized clinical trial, double-blind, placebo-controlled study with the goal to assess the influence of using N-AcetylCysteyn (NAC) for prevention of AKI (Acute Kidney Injury) in post operatory of valve replacement until their discharge or death

NCT ID: NCT03323619 Not yet recruiting - Anesthesia Clinical Trials

Impact of Anesthesia Technique on Post-operative Delirium After Transcatheter Aortic Valve Implantation

Start date: November 2, 2017
Phase: N/A
Study type: Observational

Aortic stenosis is a frequent valvulopathy in Europe and North America. It occurs mainly over 65 years (2-7% of the population over 65 years). Treatment of symptomatic stenosis is an indication of aortic valve replacement. For patients with high surgical risk (EuroSCORE II> 6), TAVI (Transcatheter Aortic Valve Implantation) is recommended. This type of procedure concerns elderly patients (75-80 years on average in the literature) therefore the anesthesia technique must be optimal. The postoperative complications are, on the one hand, well-described surgical complications (Cardiogenic shock, bleeding, rhythm disorders, renal insufficiency) and, on the other hand, those related to anesthesia which are less well characterized. There is no consensus on best anesthesia technique for TAVI procedure managment. Between teams practices are different. It may consist of general anesthesia (GA) or local anesthesia with sedation (LASed). Elderly anesthesia has specific complications, including acute cerebral disturbances (delirium) usually occurring within 24 to 48 hours postoperatively and up to 7 days. It is recommended to screen delirium for patients admitted in intensive care using the CAM-ICU scale. The aim of the study is to observe the impact of the anesthesia technique (GA versus LASed) on delirium in post-operative aortic valve replacement with TAVI procedure

NCT ID: NCT03230474 Completed - Clinical trials for Post-Op Complication

a Small Dose of Naloxone,Minimize Intrathecal Morphine Side Effects

Start date: May 2016
Phase: N/A
Study type: Interventional

I.V naloxone decreases incidence and severity of the common morphine side effects (pruritis, nausea/emesis, constipation, urinary retention, respiratory depression and undesirable sedation) so using it as additive to intrathecal morphine in patients undergoing anal surgeries under spinal anesthesia may be beneficail

NCT ID: NCT03223441 Completed - Arterial Stiffness Clinical Trials

Pulse Wave Velocity as a Predictor for Postoperative Cardiovascular Events

Start date: June 2015
Study type: Observational

Vascular stiffness increases as a person ages, due to the repetitive stress that is put on the vascular system which causes changes in the elasticity of the vessel walls. The increased stiffness of the arteries puts added stress on the circulatory system. This rise in stiffness has been shown to be associated with an increased risk of cardiovascular events, in both presumably healthy patients, as well as elderly patients The current method for assessing perioperative cardiac risk is the Goldman's Revised Cardiac Risk Index (RCRI). This method, however, does not include a direct measurement of arterial stiffness. Applanation tonometry is a non-invasive technique that has been shown to reliably provide indices of arterial stiffness While the use of applanation tonometry has been widely studied in general medicine, it is has not been studied for pre-operative risk assessment in surgical patients. The purpose of this investigation is to examine whether aortic stiffness is an independent risk factor for developing cardiovascular related adverse events in patients who are having major surgery under general anesthesia. Applanation tonometry will be performed on the right carotid and femoral arteries to assess carotid-femoral pulse wave velocity, a surrogate for aortic stiffness. (SphygmoCor system, AtCor Medical, Sydney, Australia). The measurement will be obtained before induction of general anesthesia in the presurgical area. Patients' medical history, intraoperative hemodynamics, and any postoperative complications will be recorded to determine significant correlations and relationships. This information will potentially help identify future patients that might be at greater risk of developing an adverse cardiovascular event following their surgical procedure.

NCT ID: NCT03192917 Not yet recruiting - Clinical trials for Erectile Dysfunction

Low-energy Extracorporeal Shockwave Treatment for Patients After Radical Prostatectomy

Start date: September 1, 2017
Phase: N/A
Study type: Interventional

The purpose of this project is to verify the relationship between low intensity shock wave treatment (LI-SWT) and increased scores in self-assessment regarding to erectile function (ED) and sexual intercourse, in patients, who has undergone a radical prostatectomy (RP). The data will be obtained from patients using international accepted sexual questionnaires prior to the LI-SWT and 5, 12 and 24 weeks following treatment.

NCT ID: NCT03186157 Recruiting - Stroke Clinical Trials

Prevalence of Trephined Syndrome After Decompressive Craniectomy

Start date: February 1, 2012
Phase: N/A
Study type: Observational

Decompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. However, it might be underestimated if the course of cognitive functions before and after cranioplasty were insufficiently documented.

NCT ID: NCT03036072 Recruiting - Clinical trials for Post-Op Complication

Delayed Rewarming for Neuroprotection in Infants Following Cardiopulmonary Bypass Surgery

Start date: May 2016
Phase: N/A
Study type: Interventional

This is an unblinded, single center, randomized study of infants with congenital heart disease undergoing cardiopulmonary bypass surgery, randomized to either the delayed rewarming intervention or to the standard of care (strict normothermia).

NCT ID: NCT02980770 Recruiting - Clinical trials for Obstructive Sleep Apnea

Postoperative Complications in Patients With Obesity Hypoventilation Syndrome

Start date: November 2016
Phase: N/A
Study type: Observational

Obstructive sleep apnea (OSA) and Obesity-Hypoventilation Syndrome (OHS) are common conditions in obesity, which may influence the prognosis in patients undergoing surgery. There is a need for simple screening tools to identify such patients at high risk. The current multicenter observational study aims to investigate occurrence of OSA and OHS in obese individuals undergoing elective abdominal surgery and further address its impact on perioperative and postoperative complications.
