Elective Surgical Procedures

Open Abdominal Aortic Aneurysm (AAA) repair is a high-risk surgical procedure accompanied by intense endocrine and metabolic responses to surgical stress, with subsequent activation of the inflammatory cascade, cytokine and acute-phase protein release, and bone marrow activation. There is a proven correlation of surgical stress, which patients undergoing open AAA repair are subjected to, with patient outcome, morbidity/mortality, intensive care unit stay and overall length of stay. Modern general anesthetic techniques have been revised and rely on perioperative multimodal anesthetic and analgesic strategies for improved overall patient outcome. Based on this context of a multimodal anesthetic technique and having taken into consideration the international "opioid-crisis" epidemic, an Opioid Free Anesthesia-Analgesia (OFA-A) strategy started to emerge. It is based on the administration of a variety of anesthetic/analgesic agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, involving the administration of pregabalin, ketamine, dexmedetomidine, lidocaine, dexamethasone, dexketoprofen, paracetamol and magnesium sulphate, will lead to attenuation of surgical stress response compared to a conventional Opioid-Based Anesthesia-Analgesia (OBA-A) strategy. Furthermore, the anticipated attenuation of the inflammatory response, is pressumed to be associated with equal or improved analgesia, compared to a perioperative OBA-A technique.

The goal of this clinical trial is to learn if a virtually monitored, home-based prehabilitation program is feasible and acceptable for adults undergoing major elective surgery. The main questions it aims to answer are: 1. Can researchers successfully recruit and retain participants across multiple sites? 2. Will participants adhere to the prehabilitation program at a high enough rate to justify a larger trial? Researchers will compare the prehabilitation program to standard preoperative care to see if the intervention is feasible to implement and whether it may help reduce postoperative complications. Participants will: * Be randomly assigned to receive either the prehabilitation program or usual care * Complete questionnaires and physical assessments before and after the intervention * (For those in the intervention group) Receive exercise, nutrition, and mindfulness guidance, protein supplements, and use the CloudDX virtual care platform to support their activities

Introduction: Telenursing encompasses Nursing Consultation, Interconsultation, Consulting, Monitoring, Health Education and Reception of Spontaneous Demand mediated by Information and Communication Technology. Objective: To perform a cost-effectiveness analysis of telenursing in the immediate preoperative period of adult patients undergoing elective surgeries in a university hospital of the SUS. Materials and method: Cost-effectiveness analysis nested in a clinical trial or empirical economic analysis of the piggyback evaluation type. Divided into 2 phases: a) Experimental research - randomized clinical trial to be carried out in a university hospital located in Rio de Janeiro and part of the SUS, with two parallel groups - intervention and control - with 1:1 allocation. The inclusion criteria will be adult patients, of both sexes, in the immediate preoperative period who are admitted on the day of elective surgery from their home. Patients who are hospitalized, patients in ophthalmology and obstetrics specialties, and those who will undergo examinations in the surgical center will be excluded. The sample size calculation was performed with a 95% confidence level and a sample loss of 5%, totaling 352 patients. The sampling will be random. Randomization and allocation concealment will be performed by the independent researcher. Patients in the GI will receive telenursing on the day before surgery with an anamnesis script for telenursing by the main researcher. On the day of surgery, all patients on the surgical map who came from their residence will be directed to the nursing assessment room where the auxiliary researcher will apply the in-person anamnesis script. The data will be processed by two independent researchers in an electronic spreadsheet and will be analyzed using descriptive and inferential statistics. The research will respect all legal and ethical frameworks necessary for its implementation; b) Prospective analysis of complete economic evaluation - in the piggyback evaluation modality - of the cost-effectiveness type. The effectiveness of telenursing will be verified by the outcome of surgical cancellation. A decision tree model will be used with a view to analyzing the SUS user at the local level (microcosting). The time horizon will be two days. The cost-effectiveness threshold will be 1 GDP per capita and the data analysis will include deterministic and probabilistic sensitivity. Expected results: It is expected to prove that telenursing can be a safe and efficient method for guiding patients before surgery, generating greater patient satisfaction, increasing access to information about health care for users through remote communication with nurses, reducing the waiting list by reducing surgical cancellations and possible incorporation of telenursing as a consolidated practice in the university hospital studied.

Remimazolam is primarily metabolized via CES1, and other drugs that are commonly metabolized by CES1 are known to have their pharmacokinetics and clinical effects affected by genetic polymorphisms in CES1. The goal of this observational study is to investigate the impact of the CES1 genotype on the pharmacokinetics, safety, and efficacy of remimazolam in patients undergoing elective surgery.
