Multimodal protocols such as Acceleration of Total Postoperative Recovery and Enhanced Recovery After Surgery propose a set of pre- and post-operative care to accelerate the recovery of surgical patients. However, in clinical practice, simple care such as early refeeding and use of drains are often neglected by multidisciplinary teams.
Investigate whether early postoperative refeeding determines benefits in colorectal oncological surgery; whether the patients’ clinical conditions preoperatively and the use of a nasogastric tube and abdominal drain delay their recovery.
Retrospective cohort carried out at the Cascavel Uopeccan Cancer Hospital, including adult cancer patients (age ≥18 years), from the Unified Health System (SUS), who underwent colorectal surgeries from January 2018 to December 2021.
275 patients were evaluated. Of these, 199 (75.4%) were refed early. Late refeeding (odds ratio — OR=2.1; p=0.024), the use of nasogastric tube (OR=2.72; p=0.038) and intra-abdominal drain (OR=1.95; p=0.054) increased the chance of infectious complication. Multivariate analysis showed that receiving a late postoperative diet is an independent risk factor for infectious complications. Late refeeding (p=0.006) after the operation and the placement of an intra-abdominal drain (p=0.007) are independent risk factors for remaining hospitalized for more than five days postoperatively.
Refeeding early in the postoperative period reduces the risk of infectious complications. Using abdominal drains and refeeding late (>48h) for cancer patients undergoing colorectal surgery are risk factors for hospital stays longer than five days.
According to the literature, some factors are associated with the development of postoperative complications including surgical approach, smoking, comorbidities, nutritional status, classification of the American Society of Anesthesiologists (ASA), fasting time period, and others. In the case of surgical patients, some factors are important for the assessment of the outcomes.
To investigate the factors associated with the likelihood of postoperative complications in surgical patients.
A prospective observational study was conducted with patients who were admitted to hospital more than 24 h. The following variables were investigated: nutritional risk screening, body mass index, ASA classification, fasting time, length of hospital stay, and postoperative complications. For statistical analysis, the Chi-square, Fisher’s exact, and Mann-Whitney tests were used. To investigate the risk factors associated with postoperative complications, simple and multiple Cox regression analyses were used.
In the total group of patients, there was an association between postoperative complications and men (p=0.0197), surgical risk (ASA) (p=0.0397) and length of hospital stay (p<0001); men showed a risk 2.2 times greater than women for some kind of postoperative complication (p=0.0456; PR=2.167; 95%CI 1.015–4.624). In patients undergoing gastrointestinal surgery, there was an association between postoperative complications and length of hospital stay (p<0001). In patients undergoing other surgeries, there was an association between postoperative complications and length of hospital stay (p<0001) and ASA classification (p=0.0160); ASA classification was considered a factor associated with the probability of postoperative complications (p=0.0335; PR=4.125; 95%CI 1.117–15.237).
Men in the total group of patients and the ASA 3 or 4 criteria in the group of patients undergoing other surgeries were considered factors associated with the occurrence of complications in the postoperative period.
Prolonged preoperative fasting may impair nutritional status of the patient and their recovery. In contrast, some studies show that fasting abbreviation can improve the response to trauma and decrease the length of hospital stay.
Investigate whether the prescribed perioperative fasting time and practiced by patients is in compliance with current multimodal protocols and identify the main factors associated.
Cross-sectional study with 65 patients undergoing elective surgery of the digestive tract or abdominal wall. We investigated the fasting time in the perioperative period, hunger and thirst reports, physical status, diabetes diagnosis, type of surgery and anesthesia.
The patients were between 19 and 87 years, mostly female (73.8%). The most performed procedure was cholecystectomy (47.69%) and general anesthesia the most used (89.23%). The most common approach was to start fasting from midnight for liquids and solids, and most of the patients received grade II (64.6%) to the physical state. The real fasting average time was 16 h (9.5-41.58) was higher than prescribed (11 h, 6.58 -26.75). The patients submitted to surgery in the afternoon were in more fasting time than those who did in the morning (p<0.001). The intensity of hunger and thirst increased in postoperative fasting period (p=0.010 and 0.027). The average period of postoperative fasting was 18.25 h (3.33-91.83) and only 23.07% restarted feeding on the same day.
Patients were fasted for prolonged time, higher even than the prescribed time and intensity of the signs of discomfort such as hunger and thirst increased over time. To better recovery and the patient's well-being, it is necessary to establish a preoperative fasting abbreviation protocol.
The abbreviation of perioperative fasting among candidates to elective surgery have been associated with shorter hospital stay and decreased postoperative complications.
To conduct a systematic review from randomized controlled trials to detect whether the abbreviation of fasting is beneficial to patients undergoing cancer surgery compared to traditional fasting protocols.
A literature search was performed in electronic databases: MEDLINE (PubMed), SciELO, EMBASE and Cochrane, without time restriction. Were used the descriptors: "preoperative fasting", "cancer", "diet restriction" and "perioperative period". Randomized trials were included in adults of both sexes, with diagnosis of cancer. Exclusion criteria were: use of parenteral nutrition and publications in duplicate. All analyzes, selections and data extraction were done blinded manner by independent evaluators.
Four studies were included, with a total of 150 patients, 128 with colorectal cancer and 22 gastric cancer. The articles were published from 2006 to 2013. The main outcome measures were heterogeneous, which impaired the unification of the results by means of meta-analysis. Compared to traditional protocols, patients undergoing fasting abbreviation with the administration of fluids containing carbohydrates had improvements in glycemic parameters (fasting glucose and insulin resistance), inflammatory markers (interleukin 6 and 10) and indicators of malnutrition (grip strength hand and CRP/albumin ratio), and shorter hospital stay. The methodological quality of the reviewed articles, however, suggests that the results should be interpreted with caution.
The abbreviation of perioperative fasting in patients with neoplasm appears to be beneficial.
Current researches associate long fasting periods to several adverse consequences. The fasting abbreviation to 2 h to clear liquids associated with the use of drinks containing carbohydrates attenuates endocrinometabolic response to surgical trauma, but often is observed children advised to not intake food from 00:00 h till the scheduled surgical time, regardless of what it is.
To evaluate the safety of a protocol of preoperative fasting abbreviation with a beverage containing carbohydrates, and early postoperative feeding in children underwent elective small/mid-size surgical procedures during a national task-force on pediatric surgery.
Thirty-six patients were prospectively included, and for several reasons five were excluded. All 31 who remained in the study received a nutritional supplement containing 150 ml of water plus 12.5% maltodextrin 2 h before the procedure. Data of the pre-operative fasting time, anesthetic complications and time of postoperative refeeding, were collected.
Twenty-three (74.2%) were males, the median age was 5 y, and the median weight was 20 kg. The median time of pre-operative fasting was 145 min and the time of post-operative refeeding was 135 min. There were no adverse effects on the anesthetic procedures or during surgery. Post-operatively, two children (6.5%) vomited.
The abbreviation of pre-operative fasting to 2 h with beverage containing carbohydrate in pediatric surgery is safe. Early refeeding in elective small/mid-size procedures can be prescribed.

Considering the practice of preoperative fasting based on observations on the gastric emptying delay after induction and the time of this fast is closely linked to organic response to trauma, arise the question about preoperative fasting period necessary to minimize such response and support the professional with clinical and scientific evidence.
To review the aspects related to the abbreviation of preoperative fasting from the metabolic point of view, physiology of gastric emptying, its clinical benefits and the currently recommendations.
Literature review was based on articles and guidelines published in English and Portuguese, without restriction of time until January 2017, in PubMed, SciELO and Cochrane with the descriptors: surgery, preoperative fasting, carbohydrate. From the universe consulted, 31 articles were selected.
The literature suggests that the abbreviation of fasting with beverage added carbohydrates until 2 h before surgery, can bring benefits on glycemic and functional parameters, reduces hospitalization, and does not present aspiration risk of healthy patients undergoing elective surgery. Another nutrient that has been added to the carbohydrate solution and has shown promising results is glutamine.
The abbreviation of preoperative fasting with enriched beverage with carbohydrates or carbohydrate and glutamine seems to be effective in the care of the surgical patient, optimizing the recovery from of postoperative period.
The metabolic response to surgical trauma is enhanced by prolonged preoperative fasting, contributing to increased insulin resistance. This manifestation is more intense on the 1st and 2nd postoperative days and is directly proportional to the size of the operation.
To compare whether preoperative fasting abbreviation and early postoperative refeeding associated with intraoperative and postoperative fluid restriction interfere in the evolution of patients undergoing gastrojejunal bypass.
Eighty patients indicated for Roux-en-Y gastrojejunal bypass were selected. They were randomly divided into two groups: Ringer Lactate (RL) group, who underwent a 6 hours solids fasting, with the administration of 50 g of maltodextrin in 100 ml of mineral water 2 hours before the beginning of anesthesia; and Physiologic Solution (PS) group, who underwent a 12 hours solids and liquids fasting. Anesthesia was standardized for both groups. During the surgical procedure, 1500 ml of ringer lactate solution was administered in the RL and 2500 ml of physiological solution (0.9% sodium chloride) in the PS. In both groups, the occurrence of bronchoaspiration was analyzed during intubation, and the residual gastric volume was measured after opening the abdominal cavity. In the postoperative period in Group RL, patients started a liquid diet 24 hours after the end of the operative procedure; whilst for PS group, fasting was maintained for the first 24 hours, it was prescripted 2000 ml of physiological solution and a restricted liquid diet after 36 hours. Each patient underwent CPK, insulin, sodium, potassium, urea, creatinine, PaCO2, pH and bicarbonate dosage in the immediate postoperative period, and 48 hours later, the exams were repeated.
There were no episodes of bronchoaspiration and gastrojejunal fistulas in either group. In the analysis of the residual gastric volume of the PS and RL groups, the mean volumes were respectively 16.5 and 8.8, which shows statistical significance between the groups. In laboratory tests, there was no difference between groups in sodium; PS group showed a higher level of serum potassium (p=0.029); whilst RL group showed a higher urea and creatinine values; CPK values were even for both; PS group demonstrated a higher insulin level; pH was higher in PS group; sodium bicarbonate showed a significant difference at all times; PaCO2 values in RL group was higher than in PS. In the analysis of the incidence of nausea and flatus, no statistical significance was observed between the groups.
The abbreviation of preoperative fasting and early postoperative refeeding of Roux-en-Y gastrojejunal bypass with the application of ERAS or ACERTO Project accelerated the patient’s recovery, reducing residual gastric volume and insulin level, and do not predispose to complications.
