Boiling tube precautions

Pacific Northwest survey: posttympanostomy tube water precautions.

OBJECTIVES To determine what recommendations are given to patients or parents of patients with tympanostomy tubes regarding water exposure and to elucidate any recommendation differences between primary care and specialty care physicians. DESIGN Clinical survey. SETTING General community in the Pacific Northwest, including Washington, Oregon, and Idaho. PARTICIPANTS Physician surveys (N =...

Are water precautions necessary after tympanostomy tube placement?

BACKGROUND Tympanostomy tube insertion is one of the most commonly performed pediatric procedures in the United States. In an effort to reduce the incidence of postoperative otorrhea, many surgeons have traditionally recommended strict avoidance of water exposure to the ears. A number of studies have questioned the efficacy of such recommendations. Here we examine the evidence regarding water p...

Saturated Flow Boiling Heat Transfer in Horizontal Square Tube

The Effect of Linear Change of Tube Diameter on Subcooled Flow Boiling and Critical Heat Flux

One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...

An alternative approach to prescribing sternal precautions after median sternotomy, "Keep Your Move in the Tube".

Traditional sternal precautions, given to sternotomy patients as part of their discharge education, are intended to help prevent sternal wound complications. They vary widely but generally include arbitrary load and time restrictions (lifting no more than a specified weight for up to 12 weeks) and may prohibit common shoulder joint and shoulder girdle movements. Having observed the negative eff...
