Filter by:Randomized clinical trial: comparison between Histidine-tryptophan-ketoglutarate cardioplegia and cold blood cardioplegia for myocardial protection for Fallot tetralogy patients undergoing total repair This study aims to compare HTK cardioplegic solution and cold blood cardioplegia to provide optimal myocardial protection for a patient with tetralogy of Fallot planned for total repair.
Lobectomy is a major, high-risk surgical procedure that in addition to one-lung ventilation (OLV) exerts a potent surgical stress response. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis. The effect of anesthesia on the immune system is modest, compared to the effects induced by major surgery. However, to an immunocompromised patient, due to cancer and/or other comorbidities, the immunosuppressive effects of anesthesia may increase the incidence of post-operative infections, morbidity, and mortality. Exogenous opioids have been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes. An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological 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, will lead to an attenuated surgical stress response and attenuated immunosuppression, compared to a conventional Opioid-Based Anaesthesia-Analgesia (OBA-A) strategy. The aforementioned effects, are presumed to be associated with equal or improved analgesia and decreased incidence of postoperative infections compared to a perioperative OBA-A technique.
Background: Intraoperative hypotension increases 30-day mortality and the risks of myocardial injury and acute renal failure. Patients with inadequate volume reserve before the induction of anesthesia are highly exposed. The identification of latent hypovolemia is therefore crucial. Ultrasonographic measurement of the inferior vena cava collapsibility index (IVCCI) is able to detect volume responsiveness in circulatory shock and growing evidence support the theory that higher IVCCI can predict intraoperative hypotension. The aim of the present study is to evaluate the potential benefit of an ultrasound-based protocol for preoperative fluid optimization. The investigators will perform a randomized-controlled study involving elective surgical patients. An ultrasound-based protocol (USP) arm and a conventional fluid therapy group (CFT) are to be formed. Ultrasound examinations will be performed twice in both groups: 2 hours and 30 minutes preoperatively. The inferior vena cava and the anterior lung fields will be scanned. In the USP group the participants will receive fluid therapy according to the ultrasonographic findings: high level of IVCCI and absence of signs of pulmonary edema will indicate fluid therapy. In the CFT group the attending anesthesiologist (blinded to the results of ultrasonography) will order fluid therapy on the basis of daily routine and clinical judgement. The investigators will evaluate the incidence of intraoperative hypotension (primary outcome), postoperative metabolic status and organ functions and the amount of the administered intravenous fluids in both groups.
Providing safe and efficient anesthesia and in a field hospital is a challenging situation. This study investigated the feasibility and safety of thoracic spinal anesthesia for small-incision open cholecystectomy in a deployed field hospital.
Studies have shown that the use of dexmedetomidine before and during surgery has a good sedative, analgesic and circulatory stabilizing effect. The use of dexmedetomidine in thoracoscopic lung resection has been proven to be safe and feasible, and it has a certain degree of improvement in postoperative lung function. Combining the advantages of thoracoscopy and the previous experience of combined acupuncture and drug anesthesia technology, our team pioneered cardiopulmonary surgery without endotracheal intubation and combined needle and drug anesthesia, so that the patient was in a state of light sleep and spontaneous breathing without tracheal intubation. After completing the operation, it was found that this technical method can effectively reduce the amount of intraoperative anesthetics, improve intraoperative lung ventilation, improve lung oxygenation, achieve intraoperative organ protection, and significantly reduce complications caused by tracheal intubation , Postoperative analgesic drugs have reduced the amount of 20%, accelerate the time of exhaust and defecation, and its postoperative rehabilitation is better than conventional treatment. These results suggest that the combination of acupuncture and medicine is not only suitable for anesthesia, it can be used scientifically and rationally in postoperative analgesia, immune regulation and even the entire perioperative organ protection, creating more possibilities for patients' ERAS. In combined acupuncture and drug anesthesia, the core goal is to use acupuncture to reduce the insufficiency of anesthetics in terms of analgesia, sedation, stable circulation, and protection of organs. However, the mechanism of action behind this type of combination has not yet been improved. Efficacy kinetics or pharmacokinetics has been explained convincingly, or it is not well recognized. For example, is there a specific target in the body of acupuncture? If there is a specific target, where is the effect target? If the combined application of acupuncture and medicine produces a synergistic effect through a pharmacokinetic mechanism, its specific mechanism still needs to be clarified.
This randomised clinical trial evaluates the analgesia provided by an iPack block associated with an adductor canal block in patients who undergo anterior cruciate ligament reconstruction surgery, compared to an adductor canal block alone. The objective is to prove the superiority of this locoregional anesthesia in terms of analgesia and functional rehabilitation.
The study will include 40 patients who fulfil all the points in the inclusion and exclusion criteria will be randomized into two equal groups, each consisting of 20 patients, namely group (B) and group (C). - Group (B): will receive erector spinae plane block. - Group (C): will not receive any block. Postoperative pain score will be assessed using the FLACC scale or Face, Legs, Activity, Cry, Consolability scale immediately after extubation and at 1, 2, 4, 6, 8, 12, 18, and 24 hours. Routine postoperative analgesia in the form of intravenous paracetamol 7.5 mg/kg/6 hours will be given to all patients (the first dose is given after skin closure). Rescue analgesia in the form of 1 ug/kg fentanyl intravenously for patients if FLACC scale > 4, and the time for the first rescue analgesic administration will be recorded.
The primary aim of this study was to investigate the effect inhaled milrinone given before CPB on improving the right ventricular function measured by transesophageal echocardiography (TEE) at time of CPB separation.
Apnoeic oxygenation refers to oxygenation that occurs through the insufflation of oxygen into the lungs in the absence spontaneous respiration or positive pressure ventilation. It is used to extend the time to desaturation at induction of anaesthesia and as a primary oxygenation technique during airway surgery. The impact of high-flow nasal oxygen flow rate selection on gas exchange is poorly understood. Participants in this study will be randomised to receive a certain nasal oxygen flow rate during apnoea and its effect on gas exchange will be measured by blood gas analysis.
We propose a double-blind randomized controlled trial to evaluate the effect of intravenously administered morphine at surgery conclusion on acute postoperative pain in patients recovering from craniotomy surgery. Participating adults having craniotomy surgery will be randomized in a 1:1 ratio to intraoperative intravenous administration of 0.08 mg/kg morphine at dura closure, or a matching placebo.
