• Malnutrition is prevalent in hospitalised pts• International studies estimating the prevalence to be 20–42% (Kyle et al., 2002; Lazarus & Hamlyn, 2005; Banks et al., 2007).• Pts undergoing surgery for upper GI or colorectal cancer - particularly at risk of malnutrition (Farreras et al 2005)• Pevalence of malnutrition in pts with GI cancer : 22–62% Braga et al., 2002;; Farreras et al., 2005).
June 2009: At Risk Of Malnutrition• At risk of malnutrition rate (N=264): 48 %• Surgical pts at risk of malnutrition N=37 : 52.9 %• A follow on study , only on newly admitted surg pt (N=397): 11.1 %Source: HKL Dietetic Technical Committee
Impact of malnutrition on surgical pts• Malnutrition – cause of ↑morbidity & ↑ mortality• Severe malnutrition - caused by on-going energy deficits in the postoperative period ↑ risk of infectious complications (Akbarshahi et al. 2008)
Lack of NCP/Protocol/ Not well established nutrition Guidelines/SOP screening system Inappropriate NBMDid not keep up with practice data from current trials Gastrointestinal (GI) intolerance Lack of Metabolic competency & imbalances clinical expertise InappropriatePoor Mentoring Barrier to a Successful transitional Dietary Management feeding system practices Poor Interdepartment/ Inappropriate pre/postop dietitian communication surg nutrition practices.
• Challenging - lack of enthusiasm, personal bias, individual practices• One of the key to successful dietary management• Symbiotic relationship• View your recommend. as those of a consultant-, some will be accepted & some not.
• Multidisciplinary team approach-ward rounds• Meet their needs-provide useful data & info that cancontributes to achievement oftreatment goals & plan-Organized in form of writtencommunications & documentationto relay this need-to-knowinformation•Take the initiative -Don’t rely onphysicians to read recommend. forchanges in the treatment plan.Contact them by pager, phone toensure recom. received
• Invite physician for a talk/CME regularly & offer to sent them the current relevant articles or journal especially those obviously not implementing current evidence surgical nutrition practice• A chance for open interdepartmental communication on setting up a way of practice or system
Case Study• 77 years old/ / Malay/Female• Admitted to surgic ward 28/4/2012• For neck exploration, debulking of thyroid Ca, tracheostomy & gastrostomy• Known case of HPT

Management:1. Suggest to change IVD NS 2 Θ to IVD D5% 2 Θ (200kcal).2. Change bolus feeding to intermittent feeding pump feeding & restart feeding with predigested formula until diarrhea improved. (KIV for high fibre formula later)3. Dietary regimen planed in two step only (Fast step up) at rate 60 cc/h- 120 cc/h (full feeding)
4. Start probiotic b.d during rest hour5. Suggest to con’t ORS – PRN Outcome: Diarrhea resolved within 24 H the plan was made for transitition back to bolus feeding & discharge Successfully overcome diarrhea and correct electrolyte imbalance, fluids inadequacy and dehydration
GASTOPARESIS• The hallmark: delayed gastric emptying in the absence of a mechanical obstruction• commonest causes: - idiopathic(36–49%) -diabetes mellitus (25–29%) -post-surgical (7–13%) (Feldman et al., 1979).
GASTOPARESIS• Post-op gastroparesis - a result of gastric, oesophageal and/or pancreato-duodenal surgery (interruption of the vagus nerve)• The obesity epidemic increasing trends for bariatric surgery, is also likely to be associated with an increase in the incidence of post-operative gastroparesis in the future.
GASTOPARESIS• Nausea & vomiting- the predominant symptoms of gastroparesis (74% & 53% of cases) - abdominal pain (45%), bloating (31%), wt loss (30%), - post-prandial fullness (23%) & early satiety (29%)• Risk of malnutrition lead oral intake, including reduced macronutrient intake, weight loss & dehydration, as well as mineral & vitamin deficiency (Ogorek et al., 1991).• These symptoms nonspecificother ‘mechanical’ causes need to be excluded• Gastroenterolgists, surgeons, radiologists & dietitians all have important roles in its diagnosis
GASTOPARESIS• mild - moderate case : dietary manipulation plays a key role in management- simple adjustment to meal routines & diets can lead to an improvement in symptoms• More severe cases-alternative feeding routes play an important role Keld et al. 2011. Pathogenesis, investigation and dietary and medical management of gastroparesis. Review. J Hum Nutr Diet, 24, pp. 421–430
Dietary management:• Principle aim : to restore & maintain nutritional status, reduce symptoms. In diabetic pts, added aim of improving glycaemic control• Moderate to severe disease- dietary management becomes more challenging – EN/PN nutrition support may be needed• Limited evidence base for dietetic management strategies because controlled studies are scarce• Majority of recommendations are based on clinical experience.
• Dietetic approaches to pts with gastroparesis can be complex- essential to have a specialist dietitian involved from the beginning of assessment (multidisciplinary team mx)• Need to get a detailed history of symptom frequency & timing, focus on the type & consistency of foods tolerated, & the timing, content & size of meals.• Evaluation of nutritional & fluid status (including weight & anthropometric measurements), glycaemic control & the presence of any vitamin & mineral deficiency is also needed.
• The main dietary components that need to be evaluated include particle size, meal size, & fat & fibre content of the meal.• Alcohol & carbonated drinks are discouraged• The overall dietary advice -diet of frequent, small, low-fibre & low fat meals with increased liquid nutrient intake (or a pureed or liquid diet• NJ rather than NG route is recommended by the National Institute for Health and Clinical Excellence (NICE, 2006)

• Absorb• water• electrolytes (Na, Ca, K)• SCFA• Vitamin synthesized by bacteria (biotin & Vit K)• moving & storing stool• Transverse colostomy may affect hydration status, electrolyte balance & cause watery stool
• promote absorption of water and sodium & regulate function of bowel (Yang et.al., 2005).• Soluble fiber able to absorb excess liquid in colon & forming gel which prevent the rapid transmit timeThicken the stool
Management:• High calorie, high protein, high fluid diet• High soluble fibre food introduced• Oral nutritional supplement with soluble fibre
Management based on anticipatedcomplication – low serum sodium• High salt diet as it is predicted that serum sodium may be reduced- Add ¼ tsp of NaCl to mixed porridge- Allow liberal soy sauce in softboiled egg during breakfast- soy sauce (liberal)
Outcome :• Improved ! By 2 nd day after intervention• Stoma output: 730 ml (loose stool)• Overall appearance: more energetic, alert and able to ambulate slowly with assistant, fair hydration• Serum sodium essentially remain normal

Pre- op NBM• Traditional surgical nutrition practices such as NBM periods can also reduce nutrient intake
• Malaysian guidelines recommend for healthy adults having an elective procedure :• Limited solid food may be taken up to 6 h prior to anaesthesia &• clear fluids totalling not more than 200 ml per hr may be taken up to 2 h prior to anaesthesia
• Malaysia Guidelines for Preoperative Fasting• The 2-4-6 rule : 2 hrs clear fluids 4 hrs breast milk 6 hrs formula milk & solids
• Fasting practices in the Gl wards of a tertiary-referral hospital (Royal Prince Alfred Hospital, Australia) (N=124 )• The amount of time on ‘Nil By Mouth’ or fluid diets & reasons for these orders• NBM: no oral, EN, PN• Inadequate diet: either NBM or receiving oral clear flds only (<2000KJ/day)
Results:• Pts admitted to the GI wards spent a mean of 19.95% of their hospital stay on ‘NBM’ diet• The mean fasting time for all procedures performed within the endoscopy dept. : 14:23 h (SD 12:36) compared to the official requirement of 6 h
Results:• The mean fasting time after major GI surgery was 57:48 h (SD 31:15), compared to the recommended 24 h• Pts with mild-to-moderate malnutrition(SGA B) spend significantly more time fasting than severely malnourished pts (SGA C).
REASONS FOR FASTING %Preparation for tests or other 35non-surgical procedureswhich accounted for 35% ofthe time spent fasting.Fasting for surgery 25Fasting to aid symptom 17managementPost-operative fasting 14No reason was recorded 9
• 2007: A prospective study among ventilated pts in Intensive Care Unit (ICU) & High Dependency Ward (HDW) at K. Lumpur Hospital (N=54)• Standards to achieve : NBM Time Less than 6 hrs before & after procedures• protocol on NBM was introduced with a letter from letter on Standards for NBM time from Head of Anesthesiology and Intensive Care Department , Source : Mages et al. 2007. HKL QA study
Outcome:• Before tracheostomy : Mean NBM time reduced significantly (17.28 + 18.89) (8.10 + 16.28) hrs• After tracheostomy: fasting time was also reduced significantly (10.85 + 7.17) (7.04 + 8.08) hrs..
Current Applied Strategy in Burns Ward• Continue EN feeding until an hour or less before the actual planned procedure time, then aspirate the gastric content out - avoid prolong NBM as usually the procedure time is not always punctual• Feeding continuation after post op for wound debridement• Appropriate feeding transition practices from EN to oral
Post-op NBM• Post-op management of GI surgical pts: traditionally been ‘NBM ’,- would allow time for the return of normal gut motility, preventing post- op vomiting & nausea.• Recent literature recommends that oral or EN should recommence within the 1 st day of major surgery-improves outcomes (Fearon et al. 2005)• Post-operative nausea is more prevalent in pts that had been fasted for a prolonged period preoperatively ( Diks et al. 2005)
• Issue of mouth care - animportant aspect of patient care inthe general surgical ward & ICUsetting•clinicians should pay moreattention : simple measure canalter surgical outcome• If neglected leading toreluctance in commencing ormaintaining an adequate dietaryintake Ford 2008.
ORAL HYGIENE IN SURG. PTS• Palliative surgical pts -particularly prone to oral morbidity• Aside from pt discomfort & general well- being, oral hygiene in ICU is important to prevent of ventilator assoc. pneumonia• Tooth brushing- ideal method of promoting oral hygiene.• Simple antiseptic mouthwashes (Chlorhexidine 0.2%) is widely used &.
