BACKGROUND During orthopedic operations, such as total hip replacement or total knee replacement, there is a lot of bone debris from bone cutting and reaming that commonly causes surgical suction devices to occlude many times, which can prolong the operative time and increase the amount of bleeding for the patient. MATERIALS AND METHODS We developed a surgical filter suction system that we ca...

Our aim was to simultaneously investigate 2 techniques for in vivo sampling of peripheral compartment pharmacokinetics after systemic administration of acetylsalicylic acid. Ten volunteers were given 2 g acetylsalicylic acid orally. Blood samples and dialysates from 4 microdialysis probes inserted in the dermis of the forearm were collected for 5 h and suction blisters were raised 1-3 h after d...

A ®eld experiment was conducted during the dry season of 1993/1994 at the Irrigation Research Farm, Institute for Agricultural Research, Samaru, Nigeria to evaluate water management options on the performance of tomato. The trial involved three furrow irrigation methods (conventional furrow, conventional furrow with cutback, and alternate furrow), two mulch treatments (without mulch and straw m...

An automated experimental system to characterize moisture-contenttotal-suction relationships for unsaturated clayey soils is described. Unlike traditional techniques requiring independent measurement of total suction and moisture content (e.g., thermocouple psychrometry and filter paper), suction is directly controBed and corresponding moisture contents are continuously monitored. The system is...

AIM To assess the suitability of ketamine for relief of pain caused by tracheal suction during ventilator treatment in newborn infants. STUDY DESIGN In a randomised, double blind, cross over trial, 16 newborn infants received placebo or 0.5, 1, or 2 mg/kg ketamine as two minute infusions in random order five minutes before four separate endotracheal suctions, with intervals of at least 12 hou...

Venturi injector is widely used in fertigation system due to its obvious advantages such as cheap and robust system without mobile pieces, simple structure, convenient to operation, stable performance, needless of external energy for operation etc. At present, the hydraulic parameters such as suction capacity (injection rate) for the most of the Venturi injectors produced domestically are not v...
