Drain vortices are among the most common observed in everyday life, yet their physics is complex due to competition of vorticity's transport and diffusion, presence viscous layers a free surface. Recently, it has become possible study experimentally drain superfluid liquid helium, fluid which simplified by absence viscosity quantisation circulation. Using Gross-Pitaevskii equation, we make simp...

OBJECTIVES This paper sought to determine if there were an association between drain placement and the incidence of wound complications. MATERIALS AND METHODS A single-center institutional review board-approved retrospective study between 2001 to 2008, comparing 680 kidney transplant patients who either had a drain placed or were left undrained. Linear regression modeling was used to adjust t...

INTRODUCTION In many facilities, drains are routinely inserted after thyroidectomy with the aim of preventing hematoma formation and accumulation of seroma. The continued use of drains may be based more on tradition rather than proven scientific evidence. OBJECTIVE To assess the benefit of drain use after thyroidectomy by determining; length of hospital stay, post operative pain and wound sep...

Background: Thyroidectomy is one of the most difficult surgical procedures. The study aims to compare thyroidectomy procedure with drain placement and without concerning hospital stay, Postoperative complications, pain assessment using a visual analog scale. Methods: A prospective comparative was designed in Department otorhinolaryngology & Head Neck Surgery---removed for blind review----. ...

Aim: To compare the outcome of laparoscopic cholecystectomy with and without drain. Study design: Randomized controlled trial Place and duration of study: Surgical department of CMH lahore medical and dental college Unit I, II, III and IV, Jinnah hospital, Lahore.6 months 15-11-2009 to 14-05-2010. Patient and methods: Five hundred and seventy cases of gallstone disease were registered who fulfi...

Objective] Recently, the effectiveness of closed wound drainage has been evaluated for various types of orthopedic surgery. Some studies showed insufficient evidence to support the routine use of a drain. In the current analysis, the efficacy of closed suction drainage in anterior spinal fusion for lumbar spinal tuberculosis was retrospectively evaluated. [Patients and Methods] Ninety-one conse...

r a 200 .046 .: +44 19 all@durh Summary Water discolouration is a major management problem for UK water companies as a proportion of the supply relies on runoff from peat-covered catchments. Many peats have been drained using surface ditches but this has been shown to lead to more severe water discolouration. Drain-blocking is now actively encouraged in UK peatlands to promote peatland habitats...
