Regional Anesthesia for Totally Awake Upper Limb Surgery in PEDiatric Population

Peripheral loco-regional anesthesia (LRA) for anesthetic purposes is a technique widely used in adults for upper limb surgery. In pediatrics, LRA is not classically considered on its own. It is usually performed for analgesic purposes during sedation or general anesthesia. It is entirely possible to carry out awakened peripheral blocks in communicating children, of school age, thus avoiding the issues of GA in pediatrics, in particular in an emergency context. The use of Emla anesthetic skin patches for punctures (perfusion and LRA) as well as the viewing of cartoons on touch tablets during treatment can improve the perception of painless care such as LRA and treatment. In pediatrics, only ropivacaine at a concentration of 0.2% has Marketing Authorization in pediatrics in children under 12 for the production of peripheral blocks. On the basis of the experience of the Claude Galien Private Hospital in this area, it seems interesting to assess the feasibility of upper limb surgery under anesthetic LRA alone with a dose of ropivacaine at the concentration 0.35% in communicating children, of school age.

Validation of the QoR-15 Score for Emergency Surgery

Recovery from surgery is a complex process, depending on the characteristics of the patient, the anesthesia used, and the time required for surgical management. In the context of emergency surgery, the perioperative period is associated with an increase in morbidity and mortality, which may lead us to suspect an alteration in the quality of recovery. Different scales to measure the quality of post-operative recovery have been developed. The QoR-40 and QoR-15 questionnaires assess recovery after elective surgery.These scoring tools accurately measure postoperative recovery by addressing key domains: pain, physical comfort, physical independence, psychological support and emotional state. Their use is recommended as an endpoint for assessing patient comfort in clinical trials, according to the Standardized Endpoints in Perioperative Medicine (StEP) initiative. In addition, monitoring of the QoR-15 is recommended by the American Society for Enhanced Recovery. A recent French translation of the QoR-15 score has been validated for use in scheduled surgery. All of these scores, regardless of the language in which they are translated, have been developed and validated in patients who have undergone scheduled surgery. Until now, no validated scoring tool has been available to assess recovery after emergency surgery, whether traumatological or not.

Hyponatremia Study (Delayed Hyponatremia After Pituitary Surgery)

Hyponatremia is defined as sodium below the normal range of 135-145. Symptomatically, it can cause patients to experience a wide range of symptoms including lethargy, headache, nausea, vomiting and in severe cases coma and even death. The goal of this study is to prospectively compare two approaches to the postoperative fluid management of patients undergoing transsphenoidal resection of a pituitary tumor or cyst to decrease the occurrence of postoperative delayed hyponatremia. One group will be placed on moderate fluid restriction and the other group will be placed on ad lib fluid intake.

General Versus Regional Anesthesia and Postoperative Sleep Quality

Major surgery can lead to postoperative disturbances in sleep patterns with subjective deterioration of sleep quality according to patients' reports as well as objective alterations of sleep architecture, as recorded by polysomnography Factors implicated in postoperative sleep disturbances include but are not limited to the severity of the surgical procedure, the neuroendocrine response to surgery, inadequate treatment of postoperative pain and external factors interfering with sleep, such as light, noise and therapeutic procedures There are no adequate data from current literature as to whether regional anesthesia is superior to general anesthesia regarding postoperative sleep quality in patients subjected to either mode of anesthesia. So, the aim of this study will be to assess the effect of two different anesthetic techniques (general versus regional) in patients subjected to similar operations Patients will be assessed with the Pittsburgh Sleep Quality Questionnaire (PSQI), regarding preoperative and long term postoperative sleep quality and sleep diaries regarding early postoperative sleep quality

Comparison of Patient Reported Outcome Measures Using the BREAST-Q Questionnaire in Patients Undergoing Pre Versus Sub-pectoral Implant Based Immediate Breast Reconstruction.

The PROM Q study aims to compare patient reported outcome measures (PROMs) in patients undergoing mastectomy and immediate implant based breast reconstruction (IBR). This is the commonest form of breast reconstruction and current advances in surgical technology have led to increasing number of patients having implants placed above the pectoral muscle (pre-pectoral), rather than below it (sub-pectoral). This has important benefits for patients including shorter surgery time, quicker recovery, and avoidance of animation deformity (visible muscle twitching of the reconstructed breast) as the pectoral muscle is not divided to cover the implant. However, potential disadvantages include rippling effect as the implant is covered by the skin and subcutaneous tissue only, as well as potentially higher risk of capsule (scar tissue) formation. By utilising a validated questionnaire (BREAST-Q), we will assess for any difference in PROMs between the two groups of patients. The results will provide valuable information for future patients when making an informed decision about their reconstruction options. This questionnaire study will include consecutive patients undergoing mastectomy and immediate IBR for breast cancer as well as for risk reduction at Leeds Teaching Hospitals NHS Trust. The study participants will undergo either pre- or sub-pectoral IBR based on their informed discussion with the clinical team. This is a non-randomised observational study.

Impact of Remimazolam on Prognosis After Bladder Cancer Surgery

Bladder cancer is one of the most common genitourinary cancers. Transurethral resection of bladder tumor (TURBT) is the standard therapy for nonmuscle invasive bladder cancer. However, patients after TURBT are at risk for recurrence and progression. Benzodiazepines are proved to inhibit proliferation of multiple types of cancer cells in vitro. Delirium is an acute onset and transient cerebral dysfunction and is associated with worse outcomes. Previous studies indicated that benzodiazepines increase incidence of postoperative delirium. Remimazolam is a new benzodiazepine with rapid onset and ultra-short activity. The aims of this study are to explore the impact of remimazolam for general anesthesia on emergency delirium and recurrence-free survival in patients undergoing bladder cancer surgery.

The Rate of Full and Empty Stomach in Elective and Emergency Pediatric Patients

Background and Aim: Pulmonary aspiration of gastric content in the perioperative period is rare, but it is an important cause of morbidity and mortality that anesthetists never want to encounter. Due to reasons such as emergency surgical procedures, communication problems with pediatric patients or their parents, impaired cognitive function, obesity, diabetes mellitus, chronic liver and kidney diseases, it is observed that there is sometimes inconsistency between the periods defined in the preoperative fasting guidelines in pediatric patients and the state of gastric content and volume encountered in clinical practice. There is a lack of data on children on this issue. In this study, primary we aimed to evaluate the incidence of empty and full stomach in pediatric patients who underwent elective and emergency surgery in our routine anesthesia practice. Also we want to determine the relationship between fasting time and qualitative assessment of gastric content. Secondary this study sought to examine whether correlation between gastric ultrasound finding and fasting time, and also to determine relationship with the current comorbidities. Design: This is a prospective, single blinded, observational study. The minimum sample size required to determine the prevalence of full stomach, 0.05, within the limits of ± 0.025 with 0.95 confidence, was calculated as 292. When calculating with the proposed equation of n = 100 + 50i to determine the factors affecting by logistic regression (here i is the number of variables in the model), the minimum number of samples required for logistic regression analysis was calculated as 300 in case of 4 independent variables in the model. n=100+50*4= 300 Methods: Pediatric patients younger than 18 yr old who are to undergo elective and emergency surgery under general anaesthesia at our hospital are enrolled in this prospective observational study between April and December 2021. Preoperative ultrasound examination of the gastric antrum are performed by one anesthesiologist who has been instructed and supervised by an experienced pediatric radiologist and who is blind to the patient's history. Ultrasonographic measurement of the gastric antral cross-sectional area (CSA) are performed in supine position and right lateral decubitus position (RLD). The gastric antrum is imaged in a sagittal plane, between the left lobe of the liver and the pancreas, at the level of the aorta, as previously described [1]. This examination allowed qualitative assessment of gastric contents according to the three-point grading scale previously described by Perlas and colleagues[2]. Grade 0 was defined by the absence of appearance of any content in a flat antrum in both the supine and the RLD positions. Grade 1 was defined by the appearance of any gastric content in the RLD position only, and Grade 2 was defined by the appearance of any content in both the RLD and the supine positions. The antral cross-sectional area is also calculated in both position, by measuring the longitudinal diameter (D1) and the anteroposterior diameter (D2) of the antrum, from serosa to serosa using this formula [3] Antral area= (? x D1 X D2) / 4. Patients' characteristic data ( age, gender, weight, height, BMI and ASA physical status classification), fasting duration, type of elective and emergency surgery, chronic disease and complications (regurgitation, pulmonary aspiration, etc.) that may develop during the peroperative period are recorded.

Inflammatory Mediators of Acute Kidney Injury in Intensive Care

Acute kidney injury (AKI) affects more than 50% of patients admitted to the intensive care unit. The most common underlying cause is sepsis. Severe AKI in combination with sepsis is associated with high mortality. The mechanisms for sepsis-induced AKI are largely unknown. Our hypothesis is that the inflammatory response to an infection cause collateral damage to host tissue and contributes to the development of AKI. In this study we want to investigate the presence of novel inflammatory mediators in patients with sepsis, patients subjected to major surgery (sterile inflammation) and non-inflamed patients and correlate their levels with the risk for AKI.
