Filter by:"In intensive care units, therapeutic paralysis has been a routine treatment method for many years in a select group of patients. Sufficient and appropriate sedation in patients undergoing therapeutic paralysis is crucial to prevent awareness and reduce the risk of excessive sedation. Both inadequate and excessive sedation levels can be highly detrimental to the patient. Clinical assessment may not always provide accurate information regarding sedation depth. Recently, the frequency and workload of therapeutic paralysis treatment in intensive care units have increased due to COVID-19 pneumonia. Therefore, the investigators believe that inadequate sedation may be common in these patients. Processed electroencephalogram parameters such as bispectral index or patient state index (PSI), routinely used in operating rooms and intensive care units, are commonly used to indicate sedation depth. In this study, the investigators aimed to determine sedation levels in patients during paralysis, assess the prevalence of inadequate or excessive sedation, and observe the doses of sedatives and analgesics used."
Some changes in the patient's cognitive state are observed during the recovery period from general anesthesia. This period of behavioral dysregulation has been called emergence agitation (EA) and emergence delirium (ED). ED and EA occur in the early postoperative period (often within the first 30 minutes). The incidence of ED ranges from 10% to 80% in children and is described as a distressing clinical condition by 42% of pediatric anesthesiologists. Self-harm by the child increases the risk of delayed discharge and may increase the cost of medical care. Sevoflurane is a widely used agent for the induction and maintenance of anesthesia, but its use is associated with the occurrence of ED in the pediatric population. Clinical findings are characterized by hallucinations, struggling, restlessness, crying, and disorientation. In the literature, the Pediatric Anesthesia Rescue Delirium (PAED) Scale Score is used in the diagnosis of ED and EA. This score consists of 5 criteria (maximum score 20) scored using 0-4 point scales. These criteria; The child needs to make eye contact with the caregiver, the child's movements are purposeful, the child is aware of the environment, the child is restless/angry, the child cannot be consoled. While the sensitivity of ≥10 points for the diagnosis of ED is 64% and the specificity is 86%, the sensitivity of >12 points for the diagnosis of ED is 100% and the specificity is 94.5%. Monitoring intraoperative depth of anesthesia in the adult population has been recommended by the American Society of Anesthesiologists (ASA) due to its potential benefits such as faster recovery time and lower drug dosage, as well as prevention of adverse effects such as the incidence of hypotension. The use of anesthesia depth monitors used so far for children is controversial because brain development in children has not yet been completed and the calculation algorithms of these indices are based on adult EEG characteristics. There are very few studies in the literature on the relationship between anesthesia depth monitoring and EA/ED in children, and further studies are needed.
Aim: The aim of the study; to investigate whether there is a relationship between body mass index (BMI), waist circumference, and abdominal subcutaneous adipose tissue and the skin-epidural space distance measured by USG.
The investigators will conduct a 12,500-patient randomized multi-center trial to determine (i) which general anesthesia technique yields superior patient recovery experiences in any of three surgical categories ((a) major inpatient surgery, (b) minor inpatient surgery, (c) outpatient surgery) and (ii) whether TIVA confers no more than a small (0.2 %) increased risk of intraoperative awareness than INVA in patients undergoing both outpatient and inpatient surgeries
This study aimed to determine whether targeting bispectral index (BIS) readings of 55 (light anaesthesia) was associated with a lower incidence of delirium, dementia (POD), POCD and mortality but higher rates of awareness and complications than a standard of care anaesthesia blinded to depth monitoring.
To evaluate the feasibility of a pragmatic, large scale, comparative effectiveness, randomized evaluation of patient experience of intravenous propofol versus inhaled volatile anesthesia.
It is now known that the level of patients' expectations about a treatment (intervention, medication) can influence their prognosis. Positive expectations impact the effectiveness of the intervention, while negative expectations may lead to adverse events. It would therefore be useful to measure these expectations. However, there is no standardized questionnaire to report the overall level of expectation in the pre-operative phase. A team (led by Pr Meike C Shedden-Mora) has recently developed a questionnaire that aims to assess a patient's general level of expectation regarding a therapeutic intervention, taking into account the direct benefits and the expected adverse effects. This questionnaire, the brief version of the treatment expectation questionnaire (TEX-Q) is composed of 15 items. There's currently no French translation of the TEX-Q, nor has it been tested on a population scheduled for surgery. In addition to expectations regarding the surgical procedure, patients seem to have various expectations regarding the impact and specific role of anesthesia. Little literature exists on specific expectations regarding the role of anesthesia. Thus, we believe it is necessary to validate a French version of the TEX-Q questionnaire (TEX-Q-F) applied to the context of scheduled surgery, as well as to evaluate the specific expectations of anesthesia.
Perioperative measurement of the Depth of anaesthesia is currently recommended part of daily anaesthesia good clinical practice. The optimal depth of anaesthesia measured by Bispectral index could be between 40-60. The lower (over 60) depth of anaesthesia could be associated with accidental intraoperative episodes of awareness and deeper (below 40) anaesthesia could lead to higher adverse events or even haemodynamic instability.
Pediatric Validation of CONOX Monitoring device (qCON and qNOX indices) for anesthesia depth during surgery
Our aim is to investigate the effect of minimal flow anesthesia with sevoflurane on hemodynamics and arterial blood gas parameters in laparoscopic cholecystectomy operations.
