【Abstract】 Objective To discuss the mechanism of growth hormone (GH) in infection and its safety. Methods Advances in the application of GH in infection of recent years were reviewed. Results In infectious patients, GH may promote protein synthesis, strengthen the immunity of body, and protect the integrity of intestinal barrier function. But some patients present GH resistance. The safety of GH for infectious patients needs further evaluation. Conclusion GH may play a supplementary role in infection therapy, but further research is needed.
Objective To evaluate the effectiveness and safety of total enteral nutrition (TEN) versus total parenteral nutrition (TPN) in patients with severe acute pancreatitis (SAP). Methods The databases such as Pubmed (1996 to June 2011), EMbase (1984 to June 2011), Cochrane Central Register of Controlled Trials of The Cochrane Library (Issue 6, 2011) and CBM (1978 to June 2011) were electronically searched, and the relevant references of the included papers were also manually searched. Two reviewers independently screened the trials according to inclusion and exclusion criteria, extracted the data, and assessed the methodology quality. Meta-analyses were performed using the Cochrane Collaboration’s RevMan 5.1 software. Results Seven randomized controlled trials (RCTs) involving 379 patients with SAP were included. The results of meta-analyses showed that compared with TPN, TEN could significantly reduce the risk of mortality (RR=0.33, 95%CI 0.20 to 0.55, Plt;0.000 1), pancreatitis-related infections (RR=0.35, 95%CI 0.25 to 0.50, Plt;0.000 01), required rate of surgical intervention (RR=0.43, 95%CI 0.23 to 0.82, P=0.01), and incidence of multiple organ failure (MOF) (RR=0.28, 95%CI 0.17 to 0.46, Plt;0.000 01). There was no significant difference in the nutrition strategies associated complications between TPN and TEN (RR=1.16, 95%CI 0.42 to 3.22, P=0.78). Conclusion Meta-analyses show that compared with TPN, TEN can reduce the risk of mortality, pancreatitis-related infections, required rate of surgical intervention, and incidence of MOF; and it will not increase the nutrition strategies associated complications. Consequently, TEN should be considered a better choice for SAP patients as early as possible.
【Abstract】ObjectiveThere are two main functions of gastrointestinal tract, digestion and absorption, and barrier function. The latter has an important defensive effect, which keeps the body away from the invading and damaging of bacteria and endotoxin. It maintains the systemic homeostasis. Intestinal dysfunction would happen when body suffers from diseases or harmful stimulations. The more serious intestinal disorders would harm the intestinal protective mechanism, or intestinal barrier function, and bacterial/endotoxin translocation, of intestinal failure (IF) would ensue. This article provides a critical review of the evidence indicating that an increase in bacterial translocation is associated with sepsis, and even the multiple organ failure syndrome in critically ill patients. The intransit microorganisms play an essential role in the homeostasis of local and systemic immunity. MethodsAll studies published from 2000 to June 2005 about intestinal permeability, bacterial translocation, and systemic inflammatory response syndrome were located by search of PubMed. ResultsClinical and experimental studies investigating the correlation between bacterial translocation and systemic inflammatory response syndrome, associated with the damage of the gut barrier function . To keep the mucosal barrier function intact is one of the main issues in the prevention of bacterial translocation. This could be achieved by the adequate delivery of oxygen and nutrient supplementation to the gut. Enteral nutrition, probiotic can be a good choice. ConclusionWith a better understanding of the bacteriahost interactions in health and the alterations induced by critical illness, new therapies that improve the environment of both may lead to better recovery rates in intensive care unit patients.
Objective To identify evidence-based treatment choices for a patient with increased intracranial pressure after acute traumatic brain injury. Methods We searched The Cochrane Library (Issue 2, 2006), MEDLNE (1981 to August 2006) and CBMdisc (1978 to August 2006) to identity systematic reviews (SRs), randomized controlled trials (RCTs), controlled clinical trials (CCTs) and prospective cohort studies involving the efficacy and safety of pharmacotherapy and non-pharmacotherapy for increased intracranial pressure after acute traumatic brain injury. Results We found 2 SRs and 8 RCTs on pharmacotherapy, and 6 SRs and 2 RCTs on non-pharmacotherapy. Conventional-dose mannitol was no better than hypertonic saline, but was better than other intracranial pressure lowering agents. High-dose mannitol can reduce mortality and the incidence of severe disability compared with conventional-dose mannitol. There were no studies comparing high-dose mannitol and hypertonic saline. Non-pharmacotherapy was not recommended for routine use due to the lack of good quality evidence. Conclusion For patients with increased intracranial pressure after acute traumatic brain injury, mannitol is effective in reducing the mortality and the incidence of severe disability. However, more large-scale RCTs are required to compare high-dose mannitol versus other drugs. Non-pharmacotherapy is not recommended as an adjunct therapy at present.
The publication of the 2016 version of the Surviving Sepsis Campaign guidelines is a further step to the treatment of sepsis worldwide. This version of guidelines approves new definition of Sepsis-3. Overall, the new guidelines do not change the previous principle of treatment significantly. Some detailed and specific modifications have been made. Understanding and rational use of the new guidelines based on clinical practice, are the key to managing sepsis and performing accurate and effective treatment.
Objective To discuss the feasibility and safety of early enteral nutrition (EN) on treatment of severe acute pancreatitis (SAP) and its influence. Methods The advancement about application of early EN on treatment of SAP in recent years were reviewed. Results In patients with SAP, early EN via catheter placed in the jejunum could protect the integrity of intestinal barrier and reduce infectious complications. But no consensus had been reached about the starting time, ingredient and infusion mode yet. Conclusion Early EN may have positive effects on treatment of SAP, but further researches are still needed.
Objective To explore the value of combination APACHE II, Ranson with BalthazarCT Scoring System predicting the prognosis of severe acute pancreatitis (SAP). Methods The relationship between APACHE II, Ranson, Balthazar CT scoring systems and mortality of severe acute pancreatitis (SAP) patients admitted to the intensive care unit (ICU) of West China Hospital from January 1st, 2007 to December 31st, 2008 was analyzed. Results There was statistical difference between high and low score groups in the APACHE II, Ranson, BalthazarCT scoring systems. Combination APACHE II, Ranson with Balthazar CT scoring system, there was statistical difference between high and low Balthazar CT score group both in APACHE II and Ranson scoring systems. Conclusion APACHE II, Ranson combined with Balthazar scoring systems can be used as a more important clinical reference in evaluating the diagnosis and prognosis of severe acute pancreatitis.
