The effect of early oral postoperative carbohydrates feeding on postoperative outcome

Introduction: Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay. Post-operative ileus (POI) is an important reason for remaining patients not permit oral (NPO) in post-operative period. The tradition was that when patients passed flatus, they were ready to consume a liquid diet, and then a solid food diet was gradually introduced. This approach was taken to avoid aspiration, gastric and intestinal distension, and anastomotic dehiscence. Although studies demonstrated that the conventional strict feeding regimens were not necessary, many surgeons still hesitated to allow early oral feeding. There has been concern that early oral intake would result in vomiting and severe paralytic ileus with subsequent aspiration pneumonia, wound dehiscence and anastomotic leakage. This belief has become surgical dogma, unsupported by scientific evidence. Aim: to investigates the effect of early oral postoperative carbohydrates feeding on postoperative outcome. Material and methods: forty abdominal surgery patients were randomly assigned to early oral postoperative feeding group (20) or traditional feeding group (20). In the early feeding group (study group), patients were initially started on clear fluid only 16 h after surgery and progressed to liquids (after 24 h) and then soft and regular diet in next day (after 48 h). In the post-operative period, the patients were visited each 12 h and clinical signs and symptoms such as, time of passed flatus and moved their bowels, nausea and vomiting, and the length hospital stay were assessed. Conclusions: This study showed that early oral postoperative carbohydrates feeding group passed flatus and moved their bowels much sooner than the control group thus reducing the duration of POI and hospital stay, but there is no increase in occurrence of of nausea and vomiting between tow groups.

Effect of some growth conditions on thequantity and quality of carbohydrates in Chlorella vulgarisisolated from fresh water in southern Syrian

According to the algae ability in photosynthesis and carbohydrate production with high value in nutrition and industry, this research was carried out during 2015 to study the qualitative and quantitative content of carbohydrates in Chlorella vulgaris which was isolated from southern Syrian fresh water, and to determine the effect of the growth conditions; temperature (15, 25, 35 C), sodium nitrate concentration (0.1, 0.25, 0.4 g/l) and pH (6, 7, 8) on that content. The results showed that the total content was in the range of 20% to 40%;with galactose and rhamnose dominating among the rest of sugars. The temperature 15°C was the best to get the greatest total content with the highest value of starch, cellulose, hemicellulose and pectin. In addition, the low nitrate concentration 0.1 g/l was combined with the highest content of pectin and its compounds, while the glucose content was not affected by the nitrogen concentration. Related to pH effect, the acidic media was proved to be the best for the highest carbohydrate content. Moreover, cellulose, starch, and pectin increased in the alkali medium over the rest of carbohydrates.

The effects of oral preoperative carbohydrates administration on postoperative outcome

Introduction: Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay (LOHS). Traditionally, preoperative practice has been to fast the patient for up to 12 h prior to surgery. The rationale for this is to reduce gastric acidity and volume with a consequent decrease in the risk of gastric content aspiration during surgery. However, A Cochrane review found no increased risk of aspiration in patients who were allowed fluids 2–3 h prior to surgery compared to patients having undergone a traditional fasting period .. A carbohydrate-rich beverage given before anaesthesia and surgery alters metabolism from the overnight fasted to the fed state. This reduces the catabolic response (insulin resistance) after operation, which may have implications for postoperative recovery. Aim : to investigates the effect of preoperative carbohydrate treatment on postoperative ileus in adult patients undergoing abdominal surgery. Material and methods: fifty abdominal surgery patients were randomly assigned to preparation with a 12.5% carbohydrate drink (CHO) (25), or overnight fasting group (25). The CHO group were given 600 mL to drink on the evening before and 400 mL on the morning of surgery. The patients' complains of nausea and vomiting was noted, the length hospital stay and the duration of postoperative ileus (POI), was measured in tow groups. Conclusions: This study showed that pre-operative carbohydrate drink may be used safely and also improves patient's comfort as decrease rate of nausea and vomiting and reduce the length of hospital stay in patients undergoing abdominal surgery.

The effect of salinity on proline and carbohydrate contenets in three bread wheat genotypes (Triticum aestivum L.) in vegetative growth stage in hydroponic cultures

This study was carried out in 2009-2011, in the laboratories of science faculty - Tishreen University. The seeds of three genotypes: Sham8, Sakha8,AUS 29639 of bread wheat were planted in hydroponic cultures irrigated with Hoagland liquid in a growth chamber to compare the effect of three salt concentrations (0, 100,200 mm of NaCl) on proline and carbohydrate contents in three growth stages 21, 28, 35 of the experiment. There was an increase of proline and carbohydrate contents in all cultivars with increased salinity during the three growth stages of plants. Proline contents increased in Sham8 with low rates compare with Sakha8, AUS 29639. It increased in Sakha8 with the increase of salinity which reached 348% in the third growth stage in concentration 200 mm NaCl, while Proline concentration reached the highest value in AUS 29639 (524%). The carbohydrate content reached the highest value in Sakha8 in NaCl concentration 200 in the first growth stage (238070%) compared with the control, and (204.34%) in third stage in NaCl concentration 200mM compare with the control. The results of the study indicate the superiority of Sakha8, AUS 29639 in salt tolerance through accumulating suitable rates of proline and carbohydrates. AUS 29639 was more resistant to salt stress than Sakha8. We may use these results later in other physiological and genetical studies.

Chemical and Physical Changes in Olive Fruits «Ashrasi-Type II» During Growth and Maturation Period

During the season of 2002, samples of olive fruit were taken (Ashrasi type) from Ninavah horticulture’s station that belongs to the ministry of agriculture in Iraq. The purpose of this research is to study some physical and chemical characteristics during the growing period, from July until October. Those characteristics include moisture, ash, oil content, chlorophyll A & B, protein, pH and carbohydrate, In addition to fruit length, size, weight, radius, and rigidity. The results showed significant increase in moisture, oil, weight, size and length of the fruit were studied. Significant reduction was noticed in the percentages of the protein, carbohydrate, ash and the fruit rigidity. The highest values of chlorophyll were observed during The month of September. October considered as the best time to harvest olive fruits for pickle purpose.
