Perioperative anaphylaxis is associated with significant morbidity and mortality. Most textbooks describe it as a rare event of the order of 1 in 10 to 1 in 20,000 general anaesthetic cases. However, a recent study in the United Kingdom suggested that 1 in 350 cases have features suspicious of perioperative anaphylaxis. This study suggests that perioperative anaphylaxis may be under recognised and under reported. When perioperative anaphylaxis is recognised, it would be ideal to carry out investigations firstly to confirm the diagnosis of anaphylaxis and secondly to identify the causative agent. The latter can be difficult in the context of anaesthesia where the patient is exposed to several drugs and other reagents in a short space of time. One of the interesting aspects of perioperative anaphylaxis is that there is variability in its epidemiology between different countries, for example between the United Kingdom, France, Scandinavia and Australia and New Zealand. There are currently no data from Egypt to include in such comparisons and to inform clinical practice. As well as being at risk if a drug allergen is not identified, patients can also be at risk from an incorrect allergy label. The most common example of this is penicillin allergy where fewer than 10% of patients with a history of penicillin allergy are found to be allergic. Incorrect penicillin allergy labels are potentially harmful for patients attending for surgery because the label independently increases the risk of developing infection to resistant organisms, longer hospital stays and mortality.
Unwell patients in the intensive care unit (ICU) often need supplementary fluids to be given into the bloodstream through a drip in a vein (venous cannula), however too much fluid can be harmful. It can sometimes be difficult to tell whether or not a patient will benefit from extra fluids so they are given a "fluid challenge", whereby a small volume of fluid is given quickly into the cannula and the change in their status is noted. If the patient's condition improves, this suggests that the patient is "fluid responsive" and needs more fluid. A LiDCOplus haemodynamic monitor is a device used in the ICU to estimate the amount of blood ejected from the heart on each heartbeat using pressure readings obtained from a tube placed in one of the patient's arteries (arterial line). The investigators aim to determine whether or not the use of this device called makes a difference to the judgement of "fluid responsiveness" when the patient is given a fluid challenge when compared to simply using measurements of pulse and blood pressure and assessing the circulation in the patient's limbs. This will allow the investigators to determine whether or not the LiDCOplus alters the decisions made by doctors and nurses about how much fluid to give their patients and hence if it is of any benefit.
Sepsis and septic shock patients are considered to have a high risk of complications and death. Appropriate antimicrobial therapy plays an important role in determining outcomes in septic patients. However, pathophysiologic changes associated with critical illness have an impact on pharmacokinetics of antimicrobials. In addition, increasing bacterial resistance is also a growing concern, especially in intensive care units., Consequently, standard antimicrobial dose may not be sufficient to achieve pharmacokinetic/pharmacodynamic target in sepsis and septic shock patients. The purpose of this study is to compare a therapy between meropenem standard dose and meropenem high dose in the treatment of sepsis and septic shock
This is a randomized, double-blind, placebo-controlled clinical trial to compare Vitamin C versus placebo for patients presenting to the ICU with a diagnosis of septic shock.
Sepsis has been characterised as a dysregulated host response to infection. Adjunctive therapies targeting the inflammatory cascade are being increasingly explored, although to date, have failed to demonstrate consistent benefit, and sepsis continues to manifest poor outcomes. Hospital mortality in patients with septic shock remains as high as 22% in Australia and New Zealand. From a global perspective, 31 million sepsis and 19 million severe sepsis cases are expected to be treated in hospitals all over the world per year. To date, experimental data have reported that both high dose intravenous vitamin C and corticosteroids attenuate the acceleration of the inflammatory cascade and possibly reduce the endothelial injury characteristic of sepsis, enhance the release of endogenous catecholamines and improve vasopressor responsiveness. Therefore, the investigators plan to conduct a feasibility pilot prospective, multi-centre, randomised, open-label, trial in ICU patients with septic shock to test whether the intravenous administration of high dose Vitamin C (6g/d), Thiamine (400mg/d) and Hydrocortisone (200mg/d) leads to a more rapid resolution shock and vasopressor dependence.
Refractory cardiogenic shock is characterized by a decreased in cardiac output with hypo-responsiveness to increasing doses of catecholamines resulting in a profound tissular ischemia. VAECMO, by restoring a circulatory flow, could be associated to a major reperfusion syndrome which may lead some patients to multiple organ failures and death. Pathophysiology of this syndrome includes 1/an hyper-adrenergic state secondary to the over activation of the sympathetic system and 2/ a major release of pro-inflammatory cytokines. As adrenoreceptors are also exhibited on immunes cells, the pro-inflammatory state might be enhanced by the over-activation of the sympathetic system.
The study contains the result from a comparison of diagnostic outcomes about lung collapse by using lung ultrasonography as a new diagnostic test compares to fiberoptic bronchoscopy as the standard test.
The study measures the plasma concentrations of imipenem in septic shock patients and non-septic shock patients and observes hypoalbuminemia and the impact of the severity of critical illness on Vd
Less than ten years after their intial description, the comprehension of Innate Lymphoid Cells (ILCs) biology is rapidly improving. They can be classified into four subgroups (ILCs 1, 2, 3 and NK cells) on the basis of their cytokine production and transcription factor expression. They seem to be players in infectious diseases in animals but their role in human anti-bacterial defense remains unknown. In this prospective work, the investigators will compare ILCs phenotyping in ICU patients managed for a septic shock, comparing them to ICU patients without any infectious disease on their inclusion. The investigators will also make a large immune mapping in all patients, to place ILCs in the global immune depressed state observed in septic patients.
