Mini-invasive Approaches to Aortic Surgery
SurgerySurgical Injury4 moreThere are many different types of mini-invasive approaches to aortic surgery. Ministernotomy and anterior right minithoracotomy are the two main techniques applied for minimally invasive aortic valve replacement, but if one of them is superior in terms of patient outcomes it is not still clear. Therefore, the aim of this study is to compare the immediate and long-term outcomes of these two techniques.
fMRI and IVCM Cornea Microscopy of CXL in Keratoconus
PainPostoperative9 moreEvaluation of neuroplasticity of pain pathways and corneal afferent nerve regeneration following corneal crosslinking (CXL) in keratoconus patients using fMRI and corneal In Vivo Confocal Microscopy (IVCM).
Lower Inspiratory Oxygen Fraction for Preoxygenation
Intraoperative ComplicationsRespiratory Complication3 moreDuring the induction period of general anesthesia, surgical patients are inevitably experienced a short period of apnea for endotracheal intubation or other airway manipulation. In order to minimize the risks of hypoxemia during the establishment of artificial airway, pure oxygen (FiO2=100%) is commonly applied to the patients throughout the preoxygenation and induction period. However, high concentration of oxygen therapy has been shown to result in hyperoxemia and substantial oxygen exposure during perioperative period or critical care. There is currently no clinical evidence indicating that preoxygenation with a lower oxygen partial pressure (such as FiO2=60%) during the induction of anesthesia increases the incidence of hypoxemia or other complications. The findings of this proposed clinical study may provide fundamental evidence for the use of different oxygen concentrations in clinical anesthesia during the induction period, and determine the effects of inspired oxygen concentrations on the general postoperative outcomes during general anesthesia.
Hydroxyethyl Starch (130/0.4) for Intravascular Volume Therapy in Liver Transplantation
Intraoperative ComplicationsThere are no standardized plasma volume replacement protocols during liver transplantation surgery. The current study is designed to compare efficacy, safety, and costs of perioperative volume replacement with Voluven (Hydroxyethyl starch 130/0.4) and albumin in patients undergoing liver transplantation.
Single Incision Pelvic Floor Mesh Implants
Intra-operative ComplicationsPost Operative ComplicationsObjectives: To evaluate whether the use of single incision un-anchored small mesh implants is feasible, safe and effective for women with moderate pelvic organ prolapse. Design: Patients diagnosed with moderate pelvic organ prolapse were enrolled to undergo a single incision un-anchored mesh operation. Follow-up was 4 to 23 months. The outcome measures for this study were the operative safety and post-operative pain, adverse effects and anatomical as well as functional cure. Setting: The operations were performed under general anesthesia according with the reported surgical techniques at university and private hospitals.
TachoSil Versus Standard Surgical Treatment for Air Leakage in Pulmonary Lobectomy (TC-021-IM)
Pulmonary DiseasesIntraoperative ComplicationsThe purpose of this study is to compare the sealing efficacy and safety of TachoSil® (hereafter referred to as TachoSil) versus standard surgical treatment as the secondary management of intra-operative pulmonary air leakage after a lobectomy in subjects with lung malignancies with or without metastases.
The Use of Surgical Pleth Index in Guiding Anesthesia in Gastroenterological Surgery
Intraoperative ComplicationsIntraoperative Hypotension1 moreSurgical Pleth Index (SPI) is an intraoperative monitor aimed into detection of nociception and guidance of intraoperative opioid administration. Using such a device opioid administration could be potentially optimized during intraoperative period. this study will aim to show whether SPI could be used to reduce unwanted events and lower opioid consumption in gastroenterological surgery. The study will be blinded and randomized including two study arms with either SPI monitoring included or standard monitoring alone.
ERECTOR SPINE PLANE BLOCK VERSUS LOCAL INFILTRATION ANAESTHESIA FOR TRANSFORAMINAL PERCUTANEOUS...
Acute PainChronic Pain13 moreThe main aim of our study was to test the hypothesis that Erector spine plane block (ESP) with sedation will provide the similar employment of fentanyl and propofol during surgery as an infiltrative local anaesthesia with sedation. The primary endpoint was the quantity of fentanyl and propofol during surgery.
Effect of a Bundle of Non-pharmacological Interventions on the Stress Response to Surgery
Surgical InjuryStress5 moreRationale: Surgical trauma and post-surgical pain induce a physiological stress response that can be detrimental to the patient. Non-pharmacological interventions aimed at stress reduction are known to reduce pain scores and opioid consumption. The effect of these interventions on the surgical stress response are unknown. Objective: To assess the effect of a bundle of non-pharmacological interventions implemented in the post-anesthesia care unit on the total serum cortisol levels after intermediate and major surgery. Study design: This is a prospective before-after study. Study population: Patients scheduled for intermediate or major oncological surgery in a tertiary referral cancer center. Intervention: The implementation of a bundle of four non-pharmacological interventions aimed at stress reduction in the post-anesthesia care unit. The bundle consists of: access to music, aromatherapy, natural images on the walls and ceiling and communication techniques aimed at reduction of stress and pain. Main study parameters/endpoints: Serum cortisol levels on the first postoperative day.
Hemodilution and Outcome in Cardiac Surgery
Kidney FailureIntraoperative ComplicationsAn hematocrit of 21-25% is supposed to perform the best organ protection during cardiopulmonary bypass for cardiac surgery. The investigators want to establish the best timing for a transfusion (in patients with a predicted low hematocrit during cardiopulmonary bypass) and the efficacy of preprocedural hemodilution (in patients with a predicted high hematocrit during cardiopulmonary bypass) in patients undergoing cardiac surgery.
