BACKGROUND The established treatment for bacterial arthritis of the knee joint is arthroscopic surgery with irrigation and debridement. The aim of this article is to summarize the relevant data in treating bacterial arthritis of the knee joint, and based on these findings to present a novel irrigation suction system, tested in a cadaver study, as an additional tool in the postoperative treatmen...

BACKGROUND Total knee arthroplasty is associated with hematoma formation and extensive blood loss up to 1.5 liters. The placement of a closed suction drain to control this complication is controversial. The purpose of this study is to determine the efficacy between total knee arthroplasty without a drain and with a closed suction drain.  Methods: A retrospective cohort study was conducted betwe...

The purpose of this study was to determine the safety and cost-effectiveness of not routinely changing in-line suction catheters for patients requiring mechanical ventilation. Patients were randomly assigned to receive either no routine in-line suction catheter changes (n = 258) or in-line suction catheter changes every 24 h (n = 263). The main outcome measure was the incidence of ventilator-as...

BACKGROUND AND STUDY AIMS Abdominal discomfort and bloating are common symptoms after colonoscopy. We aimed to compare the effects of direct rectal suction with insertion of a rectal tube on reducing abdominal symptoms after unsedated colonoscopy. PATIENTS AND METHODS Consecutive patients undergoing colonoscopy were randomized to have direct rectal suction or placement of a rectal tube immedi...

The suction muffler of a reciprocating compressor is used for reducing a noise produced by pressure pulsations. According to the shape, the suction muffler is classified into one-chamber type, two-chamber type, Helmholtz-resonator type, pipe-resonator type, and so on. These mufflers are used according to the characteristics of the frequency of compressor noise. In this study, four pole paramete...

We discuss long-time behaviour of the Hele-Shaw flow in R with surface tension and injection or suction in the origin, for domains that are small perturbations of balls. After rescaling, radially symmetric solutions become stationary. We study the stability of these solutions. In particular, we show that all liquid can be removed by suction if the suction point and the geometric centre coincide...

The feeding kinematics, suction and hydraulic jetting capabilities of captive harbor seals (Phoca vitulina) were characterized during controlled feeding trials. Feeding trials were conducted using a feeding apparatus that allowed a choice between biting and suction, but also presented food that could be ingested only by suction. Subambient pressure exerted during suction feeding behaviors was d...

The ontogeny of suction feeding performance, as measured by peak suction generating capacity, was studied in the common snook, Centropomus undecimalis. Suction pressure inside the buccal cavity is a function of the total expansive force exerted on the buccal cavity distributed across the projected area of the buccal cavity. Thus, the scaling exponent of peak suction pressure with fish standard ...

The present study deals with the analysis of the effects of radiative heat transfer of micropolar fluid flow over a porous and stretching sheet in the presence of magnetic field. The dynamic viscosity and thermal conductivity coefficient have formulated by temperature-dependent relations to obtain more exact results. The flow is supposed two-dimensional, incompressible, steady and laminar and t...

The current article has investigated unsteady convective flow for MHD non-Newtonian Powell-Eyring fluid embedded porous medium over inclined permeable stretching sheet. We have pondered the thermophoresis parameter, chemical reaction, variable thermal conductivity, Brownian motion, variable heat source and variable thermal radiation in temperature and concentration profiles. Using similar trans...
