Ocorrência de úlcera por pressão em pacientes submetidos a cirurgias eletivas

OBJETIVO: Identificar a ocorrência de úlcera por pressão em pacientes submetidos a cirurgias eletivas de porte II, III e IV. MÉTODOS: Estudo de abordagem quantitativa, com delineamento de pesquisa não experimental, tipo descritivo e prospectivo. A amostra foi composta por 148 pacientes adultos, de ambos os gêneros, submetidos à cirurgia eletiva, conforme os critérios de seleção determinados previamente. RESULTADOS: Da amostra avaliada, 108 pacientes receberam alta hospitalar, três faleceram e 37 desenvolveram úlceras por pressão. Esses pacientes apresentaram 44 lesões, sendo a maioria diagnosticada de estágio II (56,8%), seguida por lesões de estágio I (40,9%) e estágio III (2,3%). As áreas corporais mais acometidas foram a região sacro/glútea (68,2%), calcâneos (18,1%), região dorsal (9%) e o pavilhão auricular (4,6%). CONCLUSÃO: A ocorrência de úlcera por pressão foi de 25% indicando a necessidade de implementação de intervenções efetivas para a prevenção desse evento adverso no perioperatório.

Lipid profile of the yolk under the influence of supplementaries sources rich in Ω-3 PUFAs in the diet of laying hens in the time

Two hundred eighty-eight 32-wk-old Hisex White laying hens were used in this research during a 10 weeks period, arranged in a 2 x 5 completely randomized factorial design, with three replicates of eight birds per treatment. Two groups: fish oil (OP) and Marine Algae (AM) with five DHA levels (120, 180, 240, 300 and 360 mg/100 g diet) were assigned including two control groups birds fed corn and soybean basal diet (CON) and a diet supplemented with AM (AM420) to study the effect of time 0, 2, 4, 6 and 8 weeks (wk) on the efficiency of egg yolk fatty acid enrichment. The means varied (p<0.01) of 17.63% (OP360) to 22.08% (AM420) is the total Polyunsaturated Fatty Acids (PUFAs) and 45.8 mg/g (OP360), 40.37 mg/g (OP360, 4 wk) to 65.82 mg/g (AM420) and 68.79 mg/g/yolk (AM120, 8 wk) for n-6 PUFAs. On the influence of sources and levels in the times, the means of n-3 PUFAs increased by 5.58 mg/g (AM120, 2 wk) to 14.16 mg/g (OP360, 6 wk) when compared to average of 3.34 mg PUFAs Ω/g/yolk (CON). Usually, the means DHA also increased from 22.34 (CON) to 176.53 mg (μ, OP360), 187.91 mg (OP360, 8 wk) and 192.96 mg (OP360, 6 wk) and 134.18 mg (μ, OP360), 135.79 mg (AM420, 6 wk), 149.75 mg DHA (AM420, 8 wk) per yolk. The opposite was observed for the means AA, so the effect of the sources, levels and times, decreased (P <0.01) of 99.83 mg (CON) to 31.99 mg (OP360, 4 wk), 40.43 mg (μ, OP360) to 61.21 mg (AM420) and 71.51 mg AA / yolk (μ, AM420). Variations of the average weight of 15.75g (OP360) to 17.08g (AM420) yolks of eggs de 32.55% (AM420) to 34.08% (OP360) of total lipids and 5.28 g (AM240) to 5.84 g (AM120) of fat in the yolk were not affected (p>0.05) by treatments, sources, levels and times studied. Starting of 2 week, the hens increased the level of n-3 PUFAs in the egg yolks, being expressively increased (p<0.01) until 4 weeks, which after the increased levels of n-3 PUFAs tended to if stabilize around of time of 8 experimental weeks, when it was more effective saturation of the tissues and yolk.
