Relationship between Fasting Times and Emergence Delirium in Children Undergoing Magnetic Resonance Imaging under Sedation. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58121861. [PMID: 36557062 PMCID: PMC9786080 DOI: 10.3390/medicina58121861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/09/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022]
Abstract
Background and Objectives: This study aimed to determine whether there is a relationship between preoperative fasting time, fasting blood glucose (FBG), and postoperative emergence delirium (ED) in pediatric patients undergoing MRI under sedation. Materials and Methods: 110 pediatric patients were included in the study. Preoperative fasting (solid-fluid) time and FBG were recorded. The development of ED in the patients who underwent MRI under sedation was evaluated with the pediatric anesthesia emergence delirium (PAED) value for 30 min every 5 min in the recovery room. PAED score of ≥10 was grouped as having ED, and a PAED score of <10 as without ED at any time. The PAED scores were compared with other variables, ASA, age, weight, MRI examination time, and FBG level and fasting times. The risk factors affecting the occurrence of ED were examined. Results: Mean age was 3.94 ± 1.53 years, mean FBG was 106.97 ± 12.53 mg/dL, fasting time was 10.75 ± 2.61 h, solid food fasting time was 11.92 ± 2.33 h, and thirst time was 10.74 ± 2.58 h. FBG was never associated with PAED measurement at any time (p > 0.05). There was a weak positive correlation between the fasting time and the 0th, 5th, and 10th minute PAED score (r = 0.225; p = 0.018, r = 0.195; p = 0.041, r = 0.195; p = 0.041). There was a weak positive correlation between the solid food fasting time and the PAED score at the 0th, 5th, 10th, 15th, and 20th minutes (r = 0.382; p < 0.001, r = 0.357; p < 0.001, r = 0.345; p < 0.001, r = 0.360; p < 0.001, r = 0.240; p < 0.001). There was a weak positive correlation between thirst time and the PAED score at the 0th, 5th, and 10th minutes (r = 0.222; p = 0.020. r = 0.192; p = 0.045, r = 0.199; p = 0.037). The incidence of ED at any time was 34.5%. Conclusions: Prolonged fasting time, solid food fasting time and thirst time are risk factors for developing postoperative ED in children undergoing MRI under sedation.

[PMID: 34337059 PMCID: PMC8298163 DOI: 10.1155/2021/9166603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Accepted: 07/10/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Preoperative fasting is important to reduce the risk of pulmonary aspiration during anesthesia. The influence of prolonged fasting time on glucose levels during anesthesia in children remains uncertain. Therefore, this study is aimed at assessing preoperative fasting time and its association with hypoglycemia during anesthesia in pediatric patients undergoing elective procedures at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. The research hypothesis of the study is as follows: there is a prolonged preoperative fasting time, and it influences the glucose levels during anesthesia among pediatric patients undergoing elective procedures at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. METHODS Institutional based cross-sectional study was conducted among 258 pediatric patients who had undergone elective procedures in a tertiary care center. A systematic sampling method was used to select study participants. The data were collected through face-to-face interviews and medical record reviews. Binary logistic regression was used to identify associated factors of hypoglycemia during anesthesia among pediatric patients undergoing elective procedures. All explanatory variables with a p value of ≤0.25 from the bivariable logistic regression model were fitted into the multivariable logistic regression model to control the possible effect of confounders, and finally, the variables which had an independent association with hypoglycemia were identified based on adjusted odds ratio with 95% confidence interval, and a p value less than 0.05 was significant. RESULTS The mean (standard deviation) fasting hours from breast milk, solid foods, and clear fluids were 7.75 (2.89), 13.25 (3.14), and 12.31 (3.22), respectively. The majority (89.9%, 57.9%, and 100%) of participants had fasted from solid, breast milk, and clear fluids for more than 8, 6, and 4 hours, respectively. More than one-fourth (26.2%) of participants were hypoglycemic immediately after induction. Residence, order of nothing per mouth, source of patient, and duration of fasting from solid foods had a significant association with hypoglycemia during anesthesia in children. CONCLUSION Children undergoing elective procedures were exposed to unnecessarily long fasting times which were associated with hypoglycemia during anesthesia.

Abstract
Perioperative pulmonary aspiration of gastric contents can induce complications of varying severity, including aspiration pneumonitis or pneumonia, which may be lethal. A 34-year-old man with no significant medical history presented to Okayama University Hospital for extraction of the third molars and incisive canal cystectomy under general anesthesia. He experienced pulmonary aspiration of clear stomach fluid during mask ventilation after induction. After aspiration occurred, the patient was immediately intubated, and suctioning was performed through the endotracheal tube (ETT). An anteroposterior (AP) chest radiograph was obtained that demonstrated atelectasis in the left lower lobe, in addition to increased peak airway pressures being noted, although SpO2 remained at 96% to 99% at an FiO2 of 1.0. The decision was made to proceed, and the scheduled procedures were completed in approximately 2 hours. A repeat AP chest radiograph obtained at the end of the operation revealed improvement of the atelectasis, and no residual atelectasis was observed on the next day. Although the patient reported following standard preoperative fasting instructions (no fluids for 2 hours preoperatively), more than 50 mL of clear fluid remained in his stomach. Because vomiting can occur despite following NPO guidelines, the need for continued vigilance by anesthesia providers and proper timely management is reinforced.

Abstract
BACKGROUND Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg-1 ·h-1 , but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss during overnight fasting, prolonged during daytime. METHODS Twenty (10 female) healthy adult volunteers, aged 24 (range 21-46) years, fasted from 22:00 until 16:00, and had their body weight and urine output measured at predefined time intervals. RESULTS The median (interquartile range) fluid deficits were 0.82 (0.73-1.00) kg, corresponding to 1.26 (1.11-1.41) g·kg-1 ·h-1 for the initial overnight fasting period, 0.59 (0.40-0.70) kg and 0.99 (0.83-1.31) g·kg-1 ·h-1 for the consecutive daytime period, and 1.47 (1.27-1.64) kg and 1.19 (1.05-1.28) g·kg-1 ·h-1 for the total period of fasting. Urine output accounted for 52% of total weight loss and was 36% of the baseline hourly level during the last four-hour period of fasting. CONCLUSIONS Ten hours of overnight fasting in young adults induces fluid deficits at the lower limit of estimated intervals referred to in clinical practice, and hourly weight loss gradually decreases further during prolonged daytime fasting. These findings indicate that current routine procedures do slightly overestimate fluid deficits resulting from prolonged fasting in perioperative clinical practice.

Abstract
Background: Although new guidelines developed by the American Society of Anesthesiologists (ASA) recommend a liberalized preoperative nutrition, authorized clinical practice guidelines or recommendations have not yet been proposed by the Lebanese Society of Anesthesia (LSA). Objective: The purpose of this study was to examine Lebanese anesthesiologists’ preoperative fasting routines and determine their knowledge and acceptance of the ASA recommendations, their attitude toward liberalized fasting, and the factors favoring their nonadherence to the new recommendations. Materials and Methods: This study was conducted in university hospitals, affiliated hospitals, and nonuniversity hospitals located in different regions of Lebanon. The survey was approved by the local ethics committee. A written questionnaire was emailed to all anesthesiologist members of the LSA which was completed anonymously. Results: Out of the 294 anesthesiologists registered in the LSA and who read the email, 118 (40.1%) completed the questionnaire. Of respondents, 90% are aware of the latest ASA practice guidelines for preoperative fasting, and 78.7% claim to apply them in their practices; however, 75% of respondents still require adult patients to stop eating after midnight, and only 45% allow them to drink clear fluids up to 2 h preoperatively. One of the main reasons for not complying with the ASA guidelines was “to allow flexibility for changes in the operating schedule.” Conclusion: A long preoperative fasting period is still the common practice for Lebanese anesthesiologists. National guideline for preoperative fasting as liberal as that recommended by the ASA should be considered.

Abstract
Background and Aims: Pre-operative fasting is a routine practice to minimise the risk of pulmonary aspiration. The leading societies of anaesthesia have adopted more liberal fasting guidelines to avoid the adverse effect of prolonged fasting. This survey was conducted to assess the knowledge, attitude and current practice of fasting guidelines among Indian anaesthesiologists and to analyse the reasons for non-compliance of these guidelines. Methods: A questionnaire consisted of 11 questions was distributed via 'Survey Monkey' software to 621 anaesthesiologists who attended the annual conference of the Indian Society of Anaesthesiologists held in Ludhiana, in 2016. American Society of Anaesthesiologists (ASA) practice guidelines for fasting were the standard of assessment. Results: The response rate to the survey was 52%. Of the respondents, 69% described correctly the practice guidelines to pre-operative fasting. Only seven percent respondents were aware of the benefits of liberalised fasting. More than 2/3rd of the respondents advised fasting as per ASA guidelines during pre-anaesthetic check-up (PAC). However, only about 50% respondents confirmed that these guidelines are actually followed in their institution. Not having control on scheduling of cases in operation theatre and poor knowledge of ward nurses and surgeons were the common reasons for non-compliance of these guidelines. Twenty four percent respondents did not use routinely any drug for aspiration prophylaxis. Conclusion: Majority of the respondents were aware of the ASA fasting guidelines. However, the implementation of the guidelines and knowledge regarding benefits of liberalised fasting is poor among respondents.

Abstract
BACKGROUND Patients are traditionally kept fasting (NPO) from midnight prior to surgery, to prevent aspiration during anesthesia. NPO time is continued postoperatively, out of concern for ileus. Prolonged periods of NPO place the pediatric population at risk for under-nutrition. Published guidelines for preoperative NPO times have been shown to be safe. The aim of this study was to investigate current pre- and postoperative feeding practices of children at a pediatric tertiary care hospital. METHODS Medical charts were used to extract data prospectively from 53 patients undergoing general, neurosurgical, or urological procedures. Date and time of NPO periods were recorded as well as the physician's postoperative diet orders and diet progression. Surgical procedures were classified as complex or noncomplex by the surgeons. Data were summarized and compared to published recommendations. RESULTS Preoperative NPO times were greater than recommended in 70% of patients studied (n=37). Median time spent NPO preoperatively was not significantly different between complex (11.5h) and noncomplex groups (10.8h). Postoperative NPO time was significantly greater for complex procedures than for noncomplex. Most patients received some postoperative NPO time, even when it was not included in the physician diet order. CONCLUSION Observed preoperative NPO time exceeded current recommendations in this study.

Abstract
Objective American Society of Anesthesiology guidelines recommend preoperative fasts of 6 hours after light snacks and 8 hours after large meals. These guidelines were designed for healthy patients undergoing elective procedures but are often applied to intubated intensive care unit (ICU) patients. ICU patients undergoing routine procedures may be subjected to unnecessary prolonged fasts. This study tests whether shorter fasts allow for better nutrition delivery and patient outcomes without increasing the risk. Study Design Randomized blinded controlled trial. Setting Tertiary academic medical center. Subjects ICU patients undergoing bedside tracheotomy. Methods Intubated ICU patients who were receiving enteral feeding and for whom bedside tracheotomy was indicated were enrolled prospectively and randomly allocated to 2 parallel preoperative fasting regimens: a 6-hour fast (control) and a 45-minute fast (intervention). Patients were assessed for aspiration, caloric delivery, metabolic markers, and infectious and noninfectious complications. Results Twenty-four patients were enrolled and randomized. There were no complications related to the procedure. There were no cases of intraoperative aspiration identified. There was a single postoperative pneumonia in the control group. Median (interquartile range) length of fast and caloric delivery were significantly different between the control group and the shortened fast group: 22 hours (18, 34) vs 14 hours (5, 25; P < .001) and 429 kcal (57, 1125) vs 1050 kcal (825, 1410; P = .01), respectively. Conclusions Shortening preoperative fasts in intubated ICU patients allowed for better caloric delivery in the preoperative period.

Abstract
BACKGROUND Preoperative fasting is a requisite before anesthesia. The main reason for preoperative fasting is to reduce gastric volume and acidity and thus decrease the risk of pulmonary aspiration. However, preoperative fasting is usually prolonged beyond the recommended time for various reasons. Despite the many adverse effects of prolonged fasting, patients sometimes fasted for a prolonged time when surgery was delayed for different reasons at the University of Gondar Hospital. The aim of this study was to assess the duration of preoperative fasting for elective surgery. METHODS A cross-sectional study was conducted from March 10 to April 10, 2013. Patients were interviewed 24 h after surgery. All 43 patients who were under anesthesia while operated on during the study period were included. RESULT Of the 43 patients included in the study, 35 were adults and 8 were children. The minimum, maximum, and mean fasting hours for food were 5, 96, and 19.60, respectively, and more than 50 % of the patients fasted from food twice as long as recommended. The minimum, maximum, and mean fasting hours for fluid were 5, 19, and 12.72, respectively. More than 95 % of the patients fasted from fluid longer than recommended. CONCLUSION Most patients fasted from both food (92 %) and fluid (95 %) longer than the fasting time recommended by the AAGBI, ASA, RCOA, and RCN fasting guidelines. Anesthetists, surgeons, and nurses need to revise operation lists every day in the operating theatres and resuscitate the patients when surgery is delayed for various reasons. A preoperative fasting guideline should be developed and implemented in the University of Gondar Hospital.

Abstract
Background Prolonged fasting increases organic response to trauma. This multicenter study investigated the gap between the prescribed and the actual preoperative fasting times in Brazilian hospitals and factors associated with this gap. Methods Patients (18–90-years-old) who underwent elective operations between August 2011 and September 2012 were included in the study. The actual and prescribed times for fasting were collected and correlated with sex, age, surgical disease (malignancies or benign disease), operation type, American Society of Anesthesiologists score, type of hospital (public or private), and nutritional status. Results A total of 3,715 patients (58.1% females) with a median age of 49 (18–94) years from 16 Brazilian hospitals entered the study. The median (range) preoperative fasting time was 12 (2–216) hours, and fasting time was longer (P<0.001) in hospitals using a traditional fasting protocol (13 [6–216] hours) than in others that had adopted new guidelines (8 [2–48] hours). Almost 80% (n=2,962) of the patients were operated on after 8 or more hours of fasting and 46.2% (n=1,718) after more than 12 hours. Prolonged fasting was not associated with physical score, age, sex, type of surgery, or type of hospital. Patients operated on due to a benign disease had an extended duration of preoperative fasting. Conclusion Actual preoperative fasting time is significantly longer than prescribed fasting time in Brazilian hospitals. Most of these hospitals still adopt traditional rather than modern fasting guidelines. All patients are at risk of long periods of fasting, especially those in hospitals that follow traditional practices.

Abstract
A treatment challenge for patients with sacral pressure ulcers is balancing the need for adequate surgical debridement with appropriate anaesthesia management. We are functioning under the hypothesis that regional anaesthesia has advantages over general anaesthesia. We describe our regional anaesthesia protocol for perioperative and postoperative management.

Abstract
AIM Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of "shortened preoperative fasting time" on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method. METHODS The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the "enhanced recovery after surgery (ERAS)" group were managed with "shortened preoperative fasting time" and "reduced laxative medication." TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored. RESULTS TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4±6.8% [12 patients] vs. -10.6±4.6% [14 patients], p<0.001). Defecation times were less in the ERAS group. Vomiting and aspiration were not observed in either group. CONCLUSION The results suggest that preoperative management with "shorted preoperative fasting time" and "reduced administration of laxatives" is effective in the maintenance of TBW in elective surgical patients.

Abstract
PURPOSE In many countries, patients are generally allowed to have clear fluids until 2-3 h before surgery. In Japan, long preoperative fasting is still common practice. To shorten the preoperative fasting period in Japan, we tested the safety and efficacy of oral rehydration therapy until 2 h before surgery. METHODS Three hundred low-risk patients scheduled for morning surgery in six university-affiliated hospitals were randomly assigned to an oral rehydration solution (ORS) group or to a fasting group. Patients in the ORS group consumed up to 1,000 ml of ORS containing balanced glucose and electrolytes: 500 ml between 2100 the night before surgery and the time they woke up the next morning and 500 ml during the morning of surgery until 2 h before surgery. Patients in the fasting group started fasting at 2100 the night before surgery. Primary endpoints were gastric fluid volume and pH immediately after anesthesia induction. Several physiological measures of hydration and electrolytes including the fractional excretion of sodium (FENa) and the fractional excretion of urea nitrogen (FEUN) were also evaluated. RESULTS Mean (SD) gastric fluid volume immediately after anesthesia induction was 15.1 (14.0) ml in the ORS group and 17.5 (23.2) ml in the fasting group (P = 0.30). The mean difference between the ORS group and fasting group was -2.5 ml. The 95% confidence interval ranged from -7.1 to +2.2 ml and did not include the noninferior limit of +8 ml. Mean (SD) gastric fluid pH was 2.1 (1.9) in the ORS group and 2.2 (2.0) in the fasting group (P = 0.59). In the ORS group, mean FENa and FEUN immediately after anesthesia induction were both significantly greater than those in the fasting group (P < 0.001 for both variables). The ORS group reported they had been less thirsty and hungry before surgery (P < 0.001, 0.01). CONCLUSIONS Oral rehydration therapy until 2 h before surgery is safe and feasible in the low-risk Japanese surgical population. Physicians are encouraged to use this practice to maintain the amount of water in the body and electrolytes and to improve the patient's comfort.

Abstract
This guideline aims to provide an overview of the present knowledge on aspects of perioperative fasting with assessment of the quality of the evidence. A systematic search was conducted in electronic databases to identify trials published between 1950 and late 2009 concerned with preoperative fasting, early resumption of oral intake and the effects of oral carbohydrate mixtures on gastric emptying and postoperative recovery. One study on preoperative fasting which had not been included in previous reviews and a further 13 studies published since the most recent review were identified. The searches also identified 20 potentially relevant studies of oral carbohydrates and 53 on early resumption of oral intake. Publications were classified in terms of their evidence level, scientific validity and clinical relevance. The Scottish Intercollegiate Guidelines Network scoring system for assessing level of evidence and grade of recommendations was used. The key recommendations are that adults and children should be encouraged to drink clear fluids up to 2 h before elective surgery (including caesarean section) and all but one member of the guidelines group consider that tea or coffee with milk added (up to about one fifth of the total volume) are still clear fluids. Solid food should be prohibited for 6 h before elective surgery in adults and children, although patients should not have their operation cancelled or delayed just because they are chewing gum, sucking a boiled sweet or smoking immediately prior to induction of anaesthesia. These recommendations also apply to patients with obesity, gastro-oesophageal reflux and diabetes and pregnant women not in labour. There is insufficient evidence to recommend the routine use of antacids, metoclopramide or H2-receptor antagonists before elective surgery in non-obstetric patients, but an H2-receptor antagonist should be given before elective caesarean section, with an intravenous H2-receptor antagonist given prior to emergency caesarean section, supplemented with 30 ml of 0.3 mol l(-1) sodium citrate if general anaesthesia is planned. Infants should be fed before elective surgery. Breast milk is safe up to 4 h and other milks up to 6 h. Thereafter, clear fluids should be given as in adults. The guidelines also consider the safety and possible benefits of preoperative carbohydrates and offer advice on the postoperative resumption of oral intake.

Abstract
BACKGROUND The increased distribution of crystalloid solution into the interstitial space may decrease the effectiveness of intravascular volume loading in patients. We investigated whether preoperative hydration status after overnight fasting affects interstitial fluid redistribution and thus the magnitude of hypotension during general anesthesia. METHODS Sixty ASA physical status I/II patients undergoing tympanoplasty fasted from midnight. Anesthesia was induced by fentanyl and propofol and maintained with sevoflurane and remifentanil. Coinciding with the induction of anesthesia, 15 mL/kg acetated Ringer solution was infused IV over 60 minutes followed by 1 mL/kg acetated Ringer solution over the next 30 minutes. Urine osmolalities after induction of anesthesia and during the study period (pre-U(osm), post-U(osm)) and percent decreases of whole-body bioelectrical resistance for extracellular fluid relative to baseline at the end of the study period (ΔR(e)) were measured. Patients with a pre-U(osm) < the 25th percentile or with a pre-U(osm) > the 75th percentile of pre-U(osm) were categorized in the hydrated or the dehydrated group, respectively. A range of variables, including mean arterial blood pressure during the 30- to 90-minute period relative to baseline, and ΔR(e), were compared between the groups. RESULTS The dehydrated group (pre-U(osm) >759.5 mOsm/kg, n = 15) had a lower age (44 vs 52 years, P = 0.049) and had a higher post-U(osm) (181 vs 55 mOsm/kg, P = 0.001) compared with the hydrated group (pre-U(osm) <378.5 mOsm/kg, n = 15). Mean arterial blood pressure during the 30- to 90-minute period relative to baseline (0.67 vs 0.67, P = 0.85) with 95% confidence interval for the difference of means (-0.070 to 0.084) and ΔR(e) (5.6% vs 6.0%, P = 0.58) with 95% confidence interval for the difference of means (-1.85% to 1.06%) were similar for the hydrated and dehydrated groups. CONCLUSIONS Preoperative dehydration after overnight fasting as measured by urine osmolality did not alter the magnitude of hypotension during general anesthesia. This finding suggests that intravascular volume loading with crystalloid solution to prevent hypotension during general anesthesia is an unfounded practice for low risk patients after overnight fasting.

Abstract
AIM Preoperative fluid and electrolyte management is usually performed by intravenous therapy. We investigated the safety and effectiveness of oral rehydration therapy (ORT) for preoperative fluid and electrolyte management of surgical patients. METHODS The study consisted of two studies, designed as a prospective observational study. In a pilot study, 20 surgical patients consumed 1000 mL of an oral rehydration solution (ORS) until 2 h before induction of general anesthesia. Parameters such as serum electrolyte concentrations, fractional excretion of sodium (FENa) as an index of renal blood flow, volume of esophageal-pharyngeal fluid and gastric fluid (EPGF), and patient satisfaction with ORT were assessed. In a follow-up study to assess the safety of ORT, 1078 surgical patients, who consumed ORS until 2 h before induction of general anesthesia, were assessed. RESULTS In the pilot study, water, electrolytes, and carbohydrate were effectively and safely supplied by ORT. The FENa value was increased at 2 h following ORT. The volume of EPGF collected following the induction of anesthesia was 5.3±5.6 mL. In the follow-up study, a small amount of vomiting occurred in one patient, and no aspiration occurred in the patients. CONCLUSION These results suggest that ORT is a safe and effective therapy for the preoperative fluid and electrolyte management of selected surgical patients.

Abstract
Perioperative patient handling should urgently be updated according to current evidence and, if none is available, at least according to physiological knowledge. To prevent pulmonary aspiration, preoperative fasting for 2 h (clear fluids) and 6 h (solid food) and abdication of 20 min for smoking is sufficient. Beta-blockage requires an indication. Bowel preparation should be abandoned and minimal invasive surgery as well as local and regional anaesthesia should be used where possible. Fluid therapy should be rational and requirement-adapted, and hypothermia, postoperative nausea and vomiting, unnecessary drains, tubes and catheters avoided. A multi-modal opioid-sparing pain therapy, sufficient oxygenation as well as early nutrition and mobilisation all play an important role for patient outcome. Recent studies have postulated that combining single-modality evidence-based care principles into a multi-modal effort to enhance postoperative recovery has improved patient outcome. Henrik Kehlet termed such a principle the 'fast-track concept', comprehending the entire perioperative phase starting with preoperative preparation, over atraumatic surgical and anaesthesiological techniques reducing the neuroendocrine stress response and also comprising the postoperative treatment. This strategy has been shown to positively influence organ function, homeostasis, morbidity, need for hospitalisation and convalescence and, therefore, to reduce costs. Despite these promising results, general implementation of evidence-based measures leaves a lot to be desired. Further development of surgical minimally invasive techniques and ongoing evaluation of procedure-specific strategies is urgently warranted.

Abstract
BACKGROUND Shorter pre-operative fasting improves clinical outcome without an increased risk. Since October 2004, German Anaesthesiology Societies have officially recommended a fast of 2 h for clear fluids and 6 h for solid food before elective surgery. We conducted a nationwide survey to evaluate the current clinical practice in Germany. METHODS Between July 2006 and January 2007, standardized questionnaires were mailed to 3751 Anaesthesiology Society members in leading positions requesting anonymous response. RESULTS The overall response rate was 66% (n=2418). Of those, 2148 (92%) claimed familiarity with the new guidelines. About a third (n=806, 34%) reported full adherence to the new recommendations, whereas 1043 (45%) reported an eased fasting practice. Traditional Nil per os after midnight was still recommended by 157 (7%). Commonest reasons reported for adopting the new guidelines were: 'improved pre-operative comfort' (84%), and 'increased patient satisfaction' (83%); reasons against were: 'low flexibility in operation room management' (19%), and 'increased risk of aspiration' (13%). CONCLUSION Despite the apparent understanding of the benefits from reduced pre-operative fasting, full implementation of the guidelines remains poor in German anaesthesiology departments.

Abstract
In 1999, the American Society of Anesthesiologists adopted preoperative fasting guidelines to enhance the quality and efficiency of patient care. Guidelines suggest that healthy, non-pregnant patients should fast six hours from solids and two hours from liquids. Although these guidelines are in place, studies suggest that providers are still using the blanket statement "NPO after midnight" without regard to patient characteristics, the procedure, or the time of the procedure. Using theory to help change provider's beliefs may help make change more successful. Rogers' Theory of Diffusion of Innovations can assist in changing long-time practice by laying the groundwork for an analysis of the benefits and disadvantages of proposed changes, such as changes to fasting orders, while helping initiate local protocols instead of additional national guidelines.

Abstract
Research has shown that preoperative fasting practices commonly are much longer than national guidelines, and medication instructions are not always given to patients before surgery. After implementation of an evidence-based preoperative fasting policy and educational efforts for health care providers at one facility, a follow up project was conducted to determine whether these efforts had improved fasting practices. The project findings indicate that preoperative fasting in excess of safe minimum guidelines persists. Improvements were found in the percentage of patients receiving specific instructions about whether to take their routine medications on the morning of surgery. Continued efforts must be made to implement best practices for preoperative fasting.

Abstract
PURPOSE OF REVIEW As a result of advances in anaesthesia and surgery, an increasing number of surgical procedures are currently possible in the ambulatory setting. Nausea/vomiting and sedation/drowsiness are often associated with delayed discharge and readmission. These symptoms are also related to pharmacological treatment as well as dehydration and fasting. The evidence that preoperative fasting and dehydration not only reduces preoperative well being, but may also affect postoperative recovery is currently being reviewed. RECENT FINDINGS In association with minor surgical procedures, rehydration with approximately 1 l fluid, and in cases with a moderate degree of surgery, such as laparoscopic surgery, 1-3 l fluid, given perioperatively will improve postoperative well being and recovery. Administration of a carbohydrate-rich beverage not only provides fluid but also counteracts the negative effects of preoperative fasting, which in turn reduces preoperative hunger and improves well being. Postoperatively, this treatment reduces insulin resistance, which may be relevant in surgery with significant postoperative stress response. Two studies on laparoscopic cholecystectomy demonstrate different results regarding effects on postoperative outcome and nausea/vomiting and further evaluation is required. SUMMARY When preoperative dehydration is corrected, postoperative well being and clinical outcome improves. Avoiding preoperative fasting by administration of carbohydrate-rich beverages improves preoperative well being while effects on postoperative recovery in patients undergoing ambulatory surgery need to be further evaluated.

Abstract
Bridging the gap between scientific evidence and its practical application is of the utmost importance in improving the quality of care and increasing patient safety. Guidelines based on evidenced-based medicine (EBM) have led to improved performances and better outcomes. However, even though scientific data are available, resistance to adopting evidence-based guidelines is still enormous. Significant barriers hinder the introduction of best medical practice into the daily clinical routine. The barriers to implementing change are complex, multifunctional, and influenced on many levels by various interests both inside and outside the health-care system. Political, organizational, financial, cultural and scientific interests are regarded as being as important as the perception of patients and health workers. Strategies need to be planned which take account of the multidimensional character of quality of care and incorporate it at the various levels. The conclusion, therefore, is that we need to combine methods and tools to tailor our interventions to the patient's needs.
