Edwards so that he can be a participant in his care and give informed consent to the treatment of his choice. The patient’s most important concern is that he is able to return to work in the shortest time possible. Given the information about the risks and beneﬁts inherent to each procedure, he elects to have the laparoscopic hernia repair. Summary Evidence-based medicine provides a systematic approach to ensuring the delivery of the highest quality of care possible to patients. It draws on the best evidence available to inform the practice of skilled and experienced clinicians. The quality of the evidence ranges from useful but potentially biased single-case studies to randomized clinical trials that meet the strictest standards of scientiﬁc rigor. Additional useful evidence can be obtained from meta-analyses, outcome studies, and practice guidelines. Evidence-based medicine has ﬁve core tenets for practicing medicine: • Clinical decision making should be based on the best available scientiﬁc evidence. The evidence-based medicine algorithm for delivering quality patient care contains ﬁve clinical objectives: 1. Providing care of the highest quality Application of the ﬁve core tenets of evidence-based medicine to the ﬁve clinical objectives promotes the optimal practice of surgery.

Cases Case 1 A 67-year-old man with obstructing esophageal cancer presents for consideration of surgical therapy. He has lost 25 pounds (15% of normal body weight) over the past 4 months, is unable to swallow anything except liquids, and has near-complete loss of appetite. He has no other past history of signiﬁcance and takes medications only for hyperten- sion. Case 2 A previously healthy 27-year-old woman is the restrained driver in a head-on collision. Nutrition Support in the Surgery Patient 43 received 4000mL of crystalloid solutions intraoperatively. Implications of Nutritional Support for Clinical Outcomes Many of the illnesses and injuries subject to surgical intervention and care promote alterations of metabolism that place patients at some risk of malnutrition-speciﬁc morbidities. It widely is assumed that mal- nutrition, especially within the context of hypermetabolism, increases the risk of infection, leads to wound-healing failure, prolongs rehabil- itation, and diminishes responses to adjunctive therapies. These consider- ations are undertaken repeatedly during the course of surgical care and may be modulated by changes in patient status and prognosis. It is axiomatic that it is always preferable to provide nutrients via the intestinal tract, but the capacity to effectively and efﬁciently do so may be altered by changes in clinical condition. The most pressing issue is whether the patient already has manifestations of “malnutrition. Unfortunately, the consensus regarding the most appropriate manner used to assess protein status is lacking, and the clinician often faces the dilemma of a continuum of nutritional situations ranging from seemingly normal to that of severe cachexia and wasting. Readily obtainable parameters, such as weight loss (especially in relation to normal or ideal body weight), circulating protein levels (such as albumin), surrogate markers of immune func- tion (such as lymphocyte count), as well as physical examination for evidence of muscle wasting (loss of temporal or other skeletal muscle mass), should be sought in all patients was done in Case 1. How such parameters translate into nutritional risk is a matter of some conjecture. There is clearly no “gold standard” for determining nutritional status because the inﬂuence of disease and injury independently may 44 S. Malnutri- tion appears to be a continuum that is inﬂuenced by altered intake and the degree of antecedent/concurrent metabolic stress. At a minimum, accurate documentation of weight loss over prior weeks and months is an indicator of the potential degree of malnutrition. They include (1) patients who are overtly malnourished and require restoration of protein and energy stores in preparation for or in conjunction with other therapies; 3. It is prudent, however, to be attentive to preoperative nutrient intake and urge sup- plemental oral feedings, where possible. The clinician is required to consider the complexity of the surgical/injury process, the magnitude and duration of hypermetab- olism, and the prospects for early return to oral feeding. Despite a general lack of class I evidence to support this decision, few would argue with such a decision. Perioperative and early feeding studies with substantial number of well- nourished or moderately malnourished patients.

Although it is most useful to use the ideal body weight of the child buy generic diabecon 60caps on-line, these methods provide a convenient starting point that can be reassessed as nutritional supplementation is given cheap 60caps diabecon amex. Monitoring Nutritional Supplementation Weight should be evaluated on a daily basis in all children buy diabecon 60caps fast delivery, and length and head circumference should be evaluated on a periodic basis in infants. Because of the inaccuracy of individual weight measurements in small premature infants, it is useful to consider the average weight change over longer periods in these patients. In general, sufﬁcient nutritional supplementation should be given to achieve a gain of 15 to 30g/day in infants and about 0. When weight assessment is difﬁcult for children receiving long-term nutritional support because of factors such as ﬂuid shifts or the addition of bandages or casts, weekly mea- surement of prealbumin values is useful to evaluate the adequacy of nutritional support. Designing a Nutritional Program The individual components of total parenteral nutrition are estimated and modiﬁed according to the infant or child’s nutritional needs (see Algorithm 35. Adequate nitrogen usage usually can be achieved by providing 25 to 35 kcal of carbohydrate and lipid calories per gram of amino acids. Carbohydrates generally are given to provide 70% and lipids to provide 30% of nonprotein calories. The starting electrolyte composition of the formula is adjusted according to the child’s age (Table 35. As with all aspects of nutritional supplementation, these parameters are reassessed regularly, and appropriate modiﬁcations are made for the child’s current needs. When an enteral route of nutrition is selected, direct modiﬁcation of individual nutritional components usually is not needed, since most commonly used formulas have ﬁxed and not modular components. Nevertheless, it is important to evaluate the key components of any given formula to ensure that individual components, particularly protein content, are met adequately in children receiving long-term support. Modiﬁed infant formulas suitable for premature infants that contain 24kcal per ounce also are available. Breast milk almost always is pre- ferred to formula and has been shown to afford a distinct outcome advantage for critically ill pediatric surgical patients. When additional calories are required, breast milk can be supplemented with commer- cially available fortiﬁers or by the addition of separate components, such as polycose or medium-chain fatty acid oils. Because the require- ment for excess free water is unique to infants, formulas that provide one calorie per milliliter such as Pediasure or Pediatric Vivonex, usually are given to children older than 1 year. Recommended daily electrolyte and trace element requirements in infants and children. Component Daily requirement Sodium 2–4mEq/kg Potassium 2–3mEq/kg Chloride 2–3mEq/kg Acetate 1–4mEq/kg Magnesium 0. Principle 3: The Child’s Weight You Should Know The Importance of Initial Weight Assessment Virtually all medical interventions in children, including nutritional support, ﬂuids, medications, and tubes, are adjusted according to patient size. For this reason, it is important to weigh every child as soon as possible at the start of any evaluation. When immediate medical intervention, such as an emergency trauma setting, precludes obtaining the patient’s weight, the child’s weight can be approximated quickly using the following formula: (Age in years ¥ 4) + 4 = Estimated weight in kilograms. Because the relative increase in weight observed in infants is greater than that observed in older children, adjustments based on weight changes may be needed on a daily basis in these patients. Estimating Maintenance Fluid Rates Maintenance ﬂuids can be estimated rapidly using the 4-2-1 rule shown in Table 35. This method usually is easier to use than the 100- 50-20 rule, since intravenous ﬂuids generally are ordered on an hourly and not on a daily basis. With the premature infant, the ﬂuid rate is modiﬁed on a nearly hourly basis, since ﬂuid shifts due to insensible losses and seemingly minor additions and deletions, such as catheter ﬂushes and blood draws, may create important ﬂuid shifts. Crystalloid boluses are given at a volume of 20cc per kilogram, and boluses of colloids, such as albumin solutions, and fresh frozen plasma generally are given at a volume of 10cc per kilogram. Administration of Blood Product Administration of blood products warrants special consideration. Several methods can be used to estimate the required volume of packed red blood cells needed to achieve a normal hematocrit. It is useful to calculate transfusion needs using more than one method in order to become familiar with each. In an emergency setting when rapid transfusion is needed, an easy estimate of required transfusion volume is 10cc per kilogram. A more accurate estimate can be obtained using the following equation: Volume of cells cc Estimated blood volume cc ( Desired Actual hematocrit change Hematocrit of packed red blood cells where the blood volume is estimated using Table 35. Regardless of the estimated volume, packed red blood cells are administered at a rate of about 2 to 3cc/kg/hour. In small infants, the response to transfusion is evaluated after every 10cc per kilogram volume in order to evaluate the need for additional transfusion and to avoid excessive transfusion.
