EXTENDED ABSTRACT The aim of this study was the optimization of pressurized irrigation networks using conventional and fuzzy numbers. In particular, the method of dynamic programming was utilized, whose implementation required the development of a program in Visual Fortran. The program was first applied using conventional numbers in three irrigation networks in the area of Kavasila (the former ...

Abstract Objective The extent of surgery, the type device used and head position may influence nasal irrigation. aim this study was to determine effectiveness topical irrigant delivery paranasal sinuses according these factors. Method Four cadaveric heads underwent four stepwise endoscopic dissections. Irrigations were evaluated after every stage using different devices (squeeze-bottle, gravity...

OBJECTIVE To determine the effectiveness of high-pressure pulsatile lavage (HPL) versus bulb syringe (BS) irrigation in removing particulate matter from metaphyseal cancellous bone. DESIGN Four grams of particulate graphite were placed in twenty distal femoral intraarticular osteotomies performed on New Zealand rabbit hind limbs. Two groups of ten specimens were then irrigated using either HP...

Background Deep wound infection in spine surgery is a debilitating complication for patients and increases costs. The objective of this prospective study was to evaluate the efficacy of wound pulse irrigation with a dilute povidone-iodine solution in the prevention of surgical site infection. Methods 50 patients undergoing spinal surgery were randomly divided into two groups (A and B) of 25 p...

A wide variety of nasal irrigation systems are currently available for improving nasal symptoms, but few studies have compared their effectiveness with respect to patient age and type of nasal disease. This pilot study aims to compare the efficacy of two irrigation systems in 20 patients (12 males and 8 females; age range, 19-54 years; mean age, 36) with acute rhinosinusitis and treated only wi...

BACKGROUND Irrigation and instrumentation during ureterorenoscopic procedures may cause increased pressure in the renal pelvis (PP) with potential harmful adverse effects. In order to assess the pressure increases during ureterorenoscopy, we measured the intraluminal renal pelvic pressure during retrograde intrarenal stone surgery (RIRS). METHODS Twelve patients admitted for RIRS were include...
