mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...
INTRODUCTION Controversy still surrounds the use of drains after total knee replacement (TKR). We compared closed suction drains, reinfusion drains and no drains by studying haemoglobin (Hb) levels, blood transfusion requirements and functional knee outcome scores in a single surgeon series. METHODS A total of 102 consecutive primary TKRs were performed by the senior author between September ...
The soil around a drain well is traditionally divided into smeared zone and undisturbed zone with constant hydraulic conductivity. In reality, hydraulic conductivity of the soil changes continuously and it may not be always appropriate to approximate its distribution with two zones. In this study, the horizontal hydraulic conductivity of the soil is described by an arbitrary function of radial ...
OBJECTIVE To determine whether bacterial colonization of drains can be reduced by local antiseptic interventions. BACKGROUND Drains are a potential source of bacterial entry into surgical wounds and may contribute to surgical site infection after breast surgery. METHODS After institutional review board approval, patients undergoing total mastectomy and/or axillary lymph node dissection were...
BACKGROUND AND AIMS There is no consensus among surgeons on the indication of putting drains for in groin hernias. In this study we aimed to investigate the factors that are associated with drain usage by comparing the clinical characteristics of patients who had drains with the patients without drains in the repair of groin hernias. MATERIAL AND METHODS The data of all groin hernia repairs f...
