Distribution assessment comparing continuous and periodic wound instillation in conjunction with negative pressure wound therapy using an agar-based model.

Negative pressure wound therapy (NPWT) is a widely accepted and effective treatment for various wound types, including complex wounds. Negative pressure with instillation was initially used as a gravity-fed system whereby reticulated, open-cell foam in the wound bed was periodically exposed to cycles of soaking with instillation solution followed by NPWT. Recent publications have alluded to positive outcomes with continuous instillation, where fluid is delivered simultaneously with negative pressure.

The effect of supporting a surgeon's wrist on their hand tremor.

Background: Operative tremor can greatly influence the outcome of certain, precise, microsurgical operations. Reducing a surgeons tremor may not only improve the operative results but decrease the operative time. Previous studies have only measured uni or bi directional tremor and therefore have been unable to calculate both the overall tremor amplitude and the tremor reduction by resting the wrists.

The effect of operating time on surgeon's hand tremor.

The objective of this prospective study, performed at two tertiary referral centers in the West Midlands, was to determine if operating has an effect on a surgeon's baseline tremor. A total of 10 head and neck surgery consultants, 2 ENT registrars and 19 normal controls participated in the study. The interventions were preoperative and postoperative tremor measurements for surgeons and pre and post-days' desk work for controls, with the main outcomes measure being the percentage change in tremor.
