AIM: To evaluate the impact of an enteral feeding protocol on administration of nutrition to surgical intensive care unit(SICU) ***: A retrospective chart review was conducted on patients initiated on enteral nutrition(EN) support during their stay in a 14 bed SICU. Data collected over a seven-day period included date of tube feed initiation, rate initiated, subsequent hourly rates, volume provided daily, and the nature and length of interruptions. The six months prior to implementation of the feeding protocol(pre-intervention) and six months after implementation(post-intervention) were compared. One hundred and four patients met criteria for inclusion; 53 were preintervention and 51 ***: Of the 624 patients who received nutrition support during the review period, 104 met the criteria for inclusion in the study. Of the 104 patients who met criteria outlined for inclusion, 64 reached the calculated goal rate(pre = 28 and post = 36). The median time to achieve the goal rate was significantly shorter in the post-intervention phase(3 d vs 6 d; P = 0.01). The time to achieve the total recommended daily volume showeda non-significant decline in the post-intervention phase(P = 0.24) and the overall volume administered daily was higher in the post-intervention phase(61.6% vs 53.5%; P = 0.07). While the overall interruptions data did not reach statistical significance, undocumented interruptions(interruptions for unknown reasons) were lower in the post-intervention phase(pre = 23/124, post = 9/96; P = 0.06).CONCLUSION: A protocol delineating the initiation and advancement of EN support coupled with ongoing education can improve administration of nutrition to SICU patients.

DESIGN OF CPW-FED ASyMMETRIC SLOT UWB ANTENNA FOR WIRELESS APPLICATION

引用

Journal of Electronics(China) 2014年第4期31卷 341-347页

作者： nagendra Kushwaha Raj Kumar R V S Ram Krishna DIAT (Deemed University) ARDE

A compact Ultra-WideBand(UWB) slot antenna is presented in this paper. The slot is modified rectangular in shape and asymmetrically cut in the ground plane. A hexagonal patch with two stepped CoPlanar Waveguide(CPW) feed is used to excite the slot. Wider impedance bandwidth is achieved due to the extra inductive reactance created by the asymmetric slot which neutralizes the capacitive reactance of the hexagonal patch. The measured impedance bandwidth of the proposed antenna is 11.85 GHz(2.9–14.75 GHz). The radiation patterns of the proposed antenna are obtained and found to be omni-directional in H-plane and bi-directional in E-plane.
