Development of indigenous enteral formulae

Athar, Nelofar, University of Western Sydney, Hawkesbury, Faculty of Science and Technology January 1995 (has links)
A procedure for preparing an enteral formula was developed, using Pakistani indigenous food items. The basis of development was that it would be nutritionally effective, easy to prepare and relatively cheap. 100 indigenous enteral diets were formulated using a computer aided master sheet in which various combinations were analysed. In order to prove the efficacy of these diets, a modified PER was carried out on 6 diets and results indicated a higher PER for the experimental diet. 29 formulations were shortlisted for preparation trials, and 2 main techniques were applied: incubation and cooking techniques. Physical and chemical analyses were carried out to assess the effect of preparation, the cooking methodologies were tried on various diets and 2 diets were shortlisted for human trials. To compare the efficacy of the indigenous enteral formula versus commercial formulae, a pilot study was carried out. Patient nutritional outcomes were assessed using biochemical parameters, and preliminary findings indicated that the experimental diet performed as well as the control diet. / Doctor of Philosophy (PhD)

Evaluation of a neonatal hyperalimentation microcomputer program

Angelier, Daniel Michael, 1950- January 1988 (has links)
A neonatal hyperalimentation microcomputer program was designed to generate labels, and calculate mixing instructions. Artificial intelligence techniques including, interviewing experts and an inference algorithm, were employed to provide decision support in identifying clinically inappropriate orders. Development cost was $10,000. The program was alpha phase tested comparing pharmacists and technicians performance. Task time was high and prone to human mathematical error for pharmacists and technicians using an electric typewriter and calculator. All subjects performed poorly with low confidence in manually determining inappropriate orders, although pharmacists scored slightly higher. Task time was decreased 17 minutes with no errors using the program. Appropriateness, confidence and composite performance were vastly improved with decision support. Pharmacists composite performance was slightly higher.

Diversos fatores contribuem para o desperdício de dieta enteral, podendo ser intrínsecos (intolerância gastrointestinal) ou extrínsecos ao paciente (exames, cirurgias), desde a prescrição da dieta até o final da sua administração. Duas formas de verificação do desperdício foram comparadas e testadas como hipóteses: a anotação de enfermagem e a medida direta do volume residual do frasco. A utilização da metodologia de Modo de Falhas e Análise de Efeitos na terapia nutricional e o estudo do desperdício da dieta trouxe pioneirismo ao estudo. Metodologia: O desperdício foi verificado por metodologia quantitativa, o volume anotado pela enfermagem e o volume medido no frasco. Foram avaliados também índices de gravidade dos pacientes e comparados com variáveis relacionadas à dieta enteral. As causas do desperdício poderiam ser encontradas em todas as etapas do processo de dieta enteral. Optou-se nesse trabalho, também, pela metodologia da análise do modo de falhas e efeitos (FMEA), mapeando as etapas, identificando os riscos potenciais e avaliando possíveis danos com pontuação acima de oito através da análise de causa raiz. Resultados/ Discussão: Houve diferença significativa em relação aos volumes de dieta desperdiçados segundo a anotação de enfermagem e o volume medido no frasco. O volume anotado pela enfermagem era maior que o medido. Esse fato pode levar a consequências importantes referentes à anotação inadequada por se tratar de um grande volume desperdiçado, segundo a anotação de enfermagem. Quanto aos índices de gravidade do paciente e variáveis referentes à dieta enteral, houve diferença significativa relacionada às variáveis sexo, idade, uso de droga vasoativa e tempo de internação. Assim, o desperdício foi maior entre os homens, não idosos, internados ... / Introduction: This study arose from the need to understand the waste of enteral nutrition in the intensive care unit. Several factors contributed to the waste of enteral feeding and may be intrinsic (gastrointestinal intolerance) or extrinsic to the patient (tests, surgeries), since the diet prescription moment until the end of its administration. Two ways of checking the waste were compared and tested as hypotheses: nurse diary and direct measurement of the residual volume of the bottle. The use of Failure Mode and Effects Analysis methodology in nutritional therapy and the study of diet waste brought originality to the work. Methodology: The waste was verified by quantitative methodology, the volume recorded by the nursing staff and the volume measured on the bottle. Severity scores of patients were also evaluated and compared with enteral nutrition-related variables. The causes of waste could be found at all stages of enteral feeding process, and in this study it was decided by the Failure Mode and Effect Analysis (FMEA) methodology, mapping process, identifying potential risks and evaluating probable damage with score above eight through root cause analysis. Results / Discussion: there was a significant difference between volumes of diet waste according to the nurse diaries and the volume measured on the bottle. The volume registered by the nursing staff was higher than the measured one. This fact may lead to important consequences regarding inappropriate notes once it's about a big volume wasted, according to the records of the nursing staff. As for patient severity scores and variables related to enteral feeding, there were meaningful differences related to sex, age, use of vasoactive drugs and hospitalization time. Thus, the waste was higher among men, not elderly, hospitalized for less than a week (waste per day), without the use of vasoactive drugs. Regarding process failures, most occurred in the period of suspension of the ...

Orientador: Elizete Aparecida Lomazi da Costa Pinto / Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas / Made available in DSpace on 2018-08-14T16:39:24Z (GMT). No. of bitstreams: 1 Beck_AnaRaquelMedeiros_D.pdf: 2495949 bytes, checksum: 11b48d31187172107996afeb7fc967d0 (MD5) Previous issue date: 2009 / Resumo: Até 50% dos tubos gástricos podem ser posicionados inadequadamente. A diversidade de técnicas e de pontos de referência utilizados para estimar a locação de sondas gástricas contribui para ocorrência de erros de posicionamento. JUSTIFICATIVA: Estudos internacionais caracterizam-se por incluir amostras reduzidas, grande amplitude nas faixas etárias e etnias específicas. OBJETIVOS: 1. Identificar o grau de correlação entre a medida do esôfago, obtida por endoscopia digestiva alta (EDA) e as medidas antropométricas e biométricas externas, tomadas em 153 crianças brasileiras, na faixa etária de 2 a 12 anos; 2. Desenvolver modelos de predição gerando equações para inserção de sondas na transição esôfago-gástrica (TEG) e no corpo do estômago (CE); 3. Comparar os valores do estudo com a medida NEX (distância do nariz, ao lóbulo da orelha até o apêndice xifóide) e com estudos internacionais. MÉTODO: Estudo analítico, observacional e transversal. Os dados foram coletados no período de janeiro de 2006 a janeiro de 2008. As medidas de biometria mensuradas foram: 1. Externas: arcada dentária superior-subnasal, subnasal-tragus, tragus-apêndice xifóide, apêndice xifóide-umbigo, subnasal-apêndice xifóide, altura e comprimento do joelho; 2. Internas: arcada dentária superior e subnasal à transição esofagogástrica e ao corpo do estômago. Modelos de predição foram ajustados para essas medidas, utilizando análise de regressão linear múltipla. Os modelos obtidos neste estudo foram comparados com os modelos provenientes de estudos internacionais, utilizando-se o coeficiente de correlação de Pearson. RESULTADOS: Altura e comprimento do joelho apresentaram as mais fortes correlações com o comprimento do esôfago, respectivamente, 0,91 e 0,88. A correlação entre a medida NEX e a medida arcada dentária superior-TEG apresentou coeficiente de correlação foi r=0,81 e com a medida ADS-CE de r=0,72. Forte correlação foi obtida entre os modelos desenvolvidos nesse estudo e modelos internacionais, r=1,00. CONCLUSÕES: A medida da altura, seguida pela medida do comprimento do joelho, apresentaram as mais fortes correlações com a medida esofágica. A medida até o corpo gástrico apresentou correlações mais fracas que as encontradas com a TEG. A medida NEX apresentou grau de correlação inferior aos obtidos nas correlações antropométricas. Houve forte correlação entre os achados no presente estudo e os valores obtidos em casuísticas internacionais. / Abstract: Errors in placement of orogastric and nasogastric feeding tubes may occur in more than 50% of procedures. The diversity of techniques and landmarks definitions used for estimating gastric tube location contributes to inadequate placement. JUSTIFICATION: International studies have included reduced samples, wide range age subjects and specific ethnic groups. OBJECTIVES: 1. Identifying correlation values between endoscopic esophageal length and anthropometric and external biometric data obtained from 153 Brazilian children (2 - 12 years old). 2. Developing statistical predictive models for inserting tubes at esophageal-gastric transition and in gastric body. 3. Comparing correlation values obtained with presented models and those obtained from international sample and with NEX (nose to ear lobe and xiphoid) measurement. METHOD: Analytical, observational and crossectional study. Data were collected from January 2006 to January 2008. The biometric measurements were: 1. External: ADS-subnasal, subnasal-tragus, tragus-xiphoid process, xiphoid processumbilicus, subnasal-xiphoid process, height and knee length; 2. Internal: superior dental arch (SDA) subnasal to the esophageal-gastric transition and to the body gastric. Correlation and determination values were obtained using multiple linear regressions. Presently predictive models were compared to international data using Pearson test. RESULTS: 1. Internal values were best correlated with height followed by knee length, respectively, 0.91 and 0.88. Correlation value between NEX and internal measurements were inferior than correlation between height and knee length, r = 0,81. Strong correlation was found between presently developed models and international samples, r=1.00. CONCLUSION: Height, followed by knee length, presented the strongest linear correlation with internal measurements. Gastric body showed weaker correlation values when compared to TEG. The NEX was hence confirmed to having a weaker correlation with the esophageal length than height. There was a strong correlation between present values and those generated from international samples. / Doutorado / Doutor em Saude da Criança e do Adolescente
