Bloodstream

The effects of caffeine can be felt as soon as 15 minutes after it is consumed. The level of caffeine in your blood peaks about one hour later and stays at this level for several hours for most people. Six hours after caffeine is consumed, half of it is still in your body. It can take up to 10 hours to completely clear caffeine from your bloodstream.

Second, food in the stomach will prevent alcohol from passing into the duodenum, which is the upper portion of the small intestine. The surface area of the small intestine is very large (about the size of a tennis court), so alcohol has more access to enter the bloodstream once it leaves the stomach. If alcohol is sequestered in the stomach it will be absorbed slower.

Once alcohol is in your bloodstream, it is carried to all organs of your body. In the majority of healthy people, blood circulates through the body in 90 seconds, thereby allowing alcohol to affect your brain and all other organs in a short amount of time. The full effects of a drink are felt within 15 to 45 minutes depending on the speed of absorption.

Once alcohol is in the bloodstream, it can only be eliminated by the enzyme alcohol dehydrogenase, sweat, urine, and breath. Drinking water and sleeping will not speed up the process. Coffee, energy drinks, and a cold shower will not sober you up faster. These might make you feel more awake, but caffeine and cold showers will not pull alcohol out of the blood - and thus will not lower your BAC level.

The NHS Standard Contract 2022/23 includes quality requirements for NHS trusts and NHS foundation trusts to minimise rates of both Clostridioides difficile (C. difficile) and of Gram-negative bloodstream infections to threshold levels set by NHS England and NHS Improvement. The thresholds for each trust, together with the methodology used to identify these, are set out in this document.

Infection, especially bloodstream infection, is the main cause of death in burn patients18. With the increasing use of antibiotics, bacterial resistance in burn patients is gradually becoming severe11. If bacterial resistance is not controlled, there may be no drugs available in the future to treat drug-resistant bacteria infections19. In anti-infective therapy, some antibiotics are used inappropriately3, which can lead to an increase in the mortality of critically ill patients infected with drug-resistant bacteria6. However, for patients with critical burns, there are few studies on whether treatment with appropriate antibiotics at admission within 24 h after injury and before positive blood cultures are observed affects prognosis. Therefore, we investigated the blood culture results of burn patients with a burn area of more than 50% who were seen in our burn ward from 2011 to 2019 and the use of antibiotics at admission and before positive blood cultures observed and analysed the effect of appropriate antibiotics use on the prognosis. Our findings provide a basis for the more rational use of antibiotics in the future.

It has been reported that for the anti-infection treatment of drug-resistant bacterial strains, the initial use of many antibiotics is not appropriate, but the use of appropriate antibiotics can reduce the mortality of patients with infection28. Therefore, for patients with positive blood cultures, the use of appropriate initial antibiotics is very important. Surprisingly, after analysing the use of antibiotics before a positive blood culture was observed, we found that when there was no significant difference in the TBSA and the third-degree burn are between the two groups of patients, whether the antibiotics that were used were appropriate had no effect on the length of hospital stay, the length of ICU stay, or in-hospital mortality. However, it has previously been reported that whether or not the initial antibiotic used for in patients with infection is appropriate is not associated with mortality36,37 and that the use of inappropriate initial antibiotics in infected patients leads to an increase in mortality25,38. Such contradictory results may be explained as follows: 1. In addition to the selection of appropriate antibiotics, whether anti-infective treatment is effective is also related to the specific bacterial resistance and the method of antibiotic administration25. If the bacteria are multidrug-resistant strains, anti-infection treatment can easily fail. In addition to the choice of antibiotics, the dose, course of treatment, and drug concentration at the site of action also have an important impact on the prognosis. 2. Our study examined the appropriateness of antibiotic treatment before a positive blood culture was observed, and the timing of blood cultures often depends on the clinical judgement of the physician. Delays in performing blood cultures will lead to the delay of anti-infection treatment and an increase patient mortality29. Therefore, it is possible that a late blood culture may lead to delays in treatment and aggravation of the disease, resulting in a poor prognosis even when the initial antibiotics are appropriate. 3. More importantly, burn infections are different from internal medicine infections. It has been reported39 that the appropriate use of antibiotics before surgery in patients with acute appendicitis does not affect surgical site infection or the length of hospital stay. For surgical infections, surgery may be more important than antibiotic treatment. Similarly, burn infections have their own characteristics. Due to the poor distribution of antibiotics in burn wounds, the use of antibiotics alone cannot prevent and treat burn wound infections and will promote the emergence of multidrug-resistant bacteria40. Moreover, regardless of whether a wound infection or bloodstream infection is present, the administration of antibiotics is only a single important part of the anti-infection treatment strategy for burn patients. Measures such as wound care, surgical management of the burn wound, and nosocomial infection control also play an important role in the prognosis of burn patients33.

This study has some limitations. (1) This study was a retrospective study that relied on electronic medical records. Some important information could not be accurately obtained, and some uncontrolled factors might affect the results. (2) This was a single-centre study, and the results may not be extendable to other centres and settings. (3) The choice of antibiotics is only a factor that affects the prognosis of burn patients with bloodstream infection. Therefore, it may lead to the result that whether antibiotics are appropriate before positive blood culture observed has no effect on the prognosis. In the future, it is necessary to further study the effect of antibiotics on the prognosis of burn patients. (4) We did not analyse the mortality in the first few days of admission, but the in-hospital mortality. Therefore, it is not known whether the use of antibiotics prophylaxis within 24 h after admission has an impact on the early mortality of admission.
