The Effect of Collagen Matrix Graft on Postoperative Palatal Fistula Formation After Cleft Palate...

Cleft Lip and Cleft PalateCleft Lip2 more

Palatal fistulas are a major burden to surgeons and patients in the management of cleft palate. Their high rate of occurrence and recurrence makes them particularly challenging even to the highly skilled surgeon. Prevention of postoperative palatal fistula is therefore of paramount importance. Closure of the nasal mucosa under tension has been proposed as a major cause of palatal fistula formation. However, depending on the presentation of the cleft palate, it may be impossible to achieve surgical closure with minimal tension. Till date, there is no universally acceptable method of preventing palatal fistula formation following cleft palate repair. And although the use of pre-surgical appliances such as Latham appliance and the use of local and distant tissues to achieve two layer closure have been proposed, the use of a superpositional collagen graft may also be used to achieve closure of the nasal mucosa with minimal or no tension during cleft palate repair. Collagen grafts have the added advantage of being more patient friendly compared to the Latham appliance which requires an initial surgery for appliance insertion before surgical cleft palate repair. They are also less technique sensitive compared to the use of local and distant tissues. The investigators therefore aim to provide high level scientific evidence of the effectiveness of collagen graft in the prevention of postoperative palatal fistula.

Effectiveness and Acceptability of Insertable Devices for Obstetric Fistula Management

Obstetric FistulaFistula4 more

The investigators propose a clinical trial and nested qualitative study to 1) quantify the effectiveness of an insertable vaginal cup to manage fistula urinary incontinence, 2) examine user and implementer acceptability, and 3) quantify fistula management cost. Two intervention models will be compared among women awaiting fistula surgery or whose surgery was unsuccessful: 1) a vaginal cup ('cup'), and 2) the cup attached via rubber tubing to a leg-secured urine collection bag ('cup+') for greater urine holding capacity.

Simulation-based Training for Nurses and Arteriovenous Fistula Puncture in Chronic Hemodialysis...

Nursing CariesArteriovenous Fistula1 more

Currently, the technique of arteriovenous fistula puncture is transmitted by companionship within hemodialysis units. Although the main principles of the technique are well known and common to all hemodialysis units, strong rationales are still lacking to standardize fine practices such as the relative position of the needles, the angle of attack of the needle at puncture, the position of the bevel at the time of puncture and once the needle is in the vascular lumen. The training of professionals using a simulation-based training program on the approach to arteriovenous fistula puncture, in a process of optimizing practices and continuous improvement of care, while respecting the principles of andragogy, seems to be a suitable tool. This program is built in a multi-professional team from nephrology, nursing and health simulation.

Benefit of Ultrasound Guidance in Arteriovenous Fistula (AVF) Cannulation in Pediatric Hemodialysis...

Arteriovenous Fistula Cannulation

The arteriovenous fistula (AVF) is the reference hemodialysis vascular access for both adult and pediatric patients. The cannulation quality is decisive for the quality of the dialysis. Difficult AVF cannulations are more frequent in pediatrics than in adults. Recent studies in adults have shown that ultrasound-guided AVF cannulation improves the cannulation quality and therefore the quality of dialysis. This study aims to prove that ultrasound-guided AVF cannulation in children will improve the quality of dialysis overall.

The Effect of Virtual Reality Application on Pain Due to Fistula Puncture in Hemodialysis Patients...

Chronic Kidney Diseases

The aim of this study is to examine the effect of virtual reality application on fistula puncture-related pain (FPi-A) in hemodialysis patients. Hypotheses of the Research: H0-1: Virtual reality application has an effect on fistula puncture-related pain in HD patients. H1-2: Virtual reality application has no effect on fistula puncture-related pain in HD patients. In the study, virtual reality will be applied in the fistula puncture procedure in patients receiving hemodialysis treatment.
