Filter by:After the initial injury, secondary insults including poor cerebral perfusion are main contributors to poor outcome and their early detection and amelioration are keystone to neurocritical care. Nonetheless, the guidelines for blood pressure management still recommend a single target blood pressure for critically ill patients: the international Guidelines for management of sepsis recommend a MAP of at least 65 mmHg; Some guidelines recognize that patients with a history of hypertension may require a higher MAP. However, these guidelines do not currently recommend cerebral autoregulation-guided therapy and leave many unanswered questions. Cerebral autoregulation is the mechanism that maintains cerebral blood supply, hence CBF approximately constant despite changes in MAP or, more precisely, despite changes in CPP. Maintaining blood pressure within the cerebral blood flow (CBF) autoregulation range (termed "optimal MAP") is associated with improved outcomes for patients. The observational data suggests that management of patients above or below CPPopt 5mmHg is associated with better outcomes and mortality than the other greater variation range.The most commonly used method for monitoring dynamic cerebrovascular reactivity is the pressure reactivity index (PRx) that uses ICP as a surrogate for CBV. However, assessing the PRx requires invasive ICP monitoring which limits its application in many clinical areas. Alternatively, in the absence of invasive intracranial pressure monitoring to determine CPP, a continuous autoregulation monitoring can be accomplished by the continuous correlation between transcranial Doppler (TCD)-measured CBF velocity of the middle cerebral artery and the mean arterial blood pressure (termed mean velocity index or Mx) . Mx is a validated index of cerebral autoregulation based on measures of cerebral perfusion pressure and mean flow velocity on transcranial doppler but is impractical for longer-term monitoring and requires system training, the results are operator-dependent. Near-infrared spectroscopy (NIRS) measurements is another alternative for real-time autoregulation monitoring in the form of a Tissue Oxygenation Index. In contrast to TCD, the NIRS sensors are very easy to apply (the probes attach to the forehead with self-adhesive pads) and do not require frequent calibration making them more suitable for long-term monitoring. Therefore, in this study, Patients in the intervention group will be monitored by continuous NIRS and invasive blood pressure monitoring. The correlation curve between ORI/THx and blood pressure will be obtained through continuous monitoring. According to the correlation curve, the optimal blood pressure which provides the optimal CPP will be determined.

Analyze the epidemiology and outcome of all patients with heart failure with reduced ejection fraction (HFrEF) presented to Asyut university hospital (AUH) and to identify factors associated with mortality and all-cause hospitalization at a duration of 6 months follow-up.
Post-operative wound issues in abdominal surgery have a significant impact on patient outcomes. The impact of different types of wound therapy are not clear in the literature. The hypothesis of this study is that NPWT has the potential to reduce Surgical Site Infections, however no study has compared the most commonly used products against standard dressings.
Tracheostomy is an important tool in the management of respiratory failure in the critically ill patient under mechanical ventilation. Although mechanical ventilation can be a lifesaving intervention, it is also known to carry several side-effects and risks. Among the most frequent complications of mechanical ventilation, obstruction of the airway secondary to a mucus plug is both life threatening and a prevalent phenomenon related to mucociliary system dysfunction, artificial airway itself and the loss of strength that prevents adequate airway clearance. The main indication of tracheostomy is the need for prolonged mechanical ventilation that usually occurs in more severe patients, this circumstance having also been related to the development of intensive care unit (ICU) acquired weakness. Currently, the approach to secretion clearance in critical patients is focused on rehabilitation therapy and humidification. Hypertonic saline (HS) is largely used in cystic fibrosis to increase airways clearance while little evidence is available in other settings although promising results have been reported. In this sense, the use of HS could be beneficial in the prevention of airway obstruction in tracheostomized critical patients.
The investigators have demonstrated that social software could improve warfarin therapy quality by Human management. however,the efficiency of management will decline if patients' number expands huge. So it is needed that a human-like and automatic management tool could replace the human work. The aim of this study is to evaluate whether an AI-based social software management model could replace human to guide warfarin therapy.
The aim of this study was to compare the prevalence of nasal carrying of SA ST398 strains in community and hospital settings, identify the factors associated with colonization of SA ST398, determine the distribution of imported and acquired cases among SA ST398 hospital cases and characterize the genetic structure of the ST398 SA population involved in colonization.
This randomized controlled trial compares vacuum-assisted percutaneous excision to open standard surgical excision in women who have high-risk or borderline, non-malignant breast lesions with respect to efficacy, safety, cosmesis and patient satisfaction.
Pain after thoracic surgery remains a challenge for anesthetists. Although VATS for lobectomy is associated with fewer complications compared to thoracotomy, pain after VATS needs to be treated with opioids. Opioids may lead to PONV, respiratory depression, sedation and pruritus. As part of multimodal analgesia and opioids sparing, several local regional techniques has been described: paravertebral block, thoracic epidural analgesia, intercostal block. To date, there is no gold standard for regional anesthesia after VATS. Serratus plane block is a local regional technique, recently described for analgesia after breast surgery and ribs fracture. In our hospital center, since 2016, we used the Serratus plane block for patients scheduled for lobectomy VATS : a local retrospective trial showed that SPB was associated with a lower consumption of morphine. The purpose of this randomized controlled double blinded study is to evaluate the analgesic effect of the Serratus plane block, added to a general anesthesia on post operative pain control after VATS lobectomy.
This study is a randomized, double-blind, placebo-controlled trial specifically designed to evaluate the preliminary feasibility, initial efficacy and safety of SGLT2 inhibitors for treating NAFLD in adolescents with obesity.
