NCT07390903
The goal of this observational study is to learn whether global longitudinal strain (GLS), measured by echocardiography, can predict difficulty separating from cardiopulmonary bypass (CPB) in adults undergoing elective cardiac surgery. The main questions it aims to answer are: * Can preoperative GLS measurement predict difficult separation from CPB? * Are GLS values associated with outcomes such as intensive care unit (ICU) stay, hospital stay, cardiac biomarkers, or 30-day mortality? Participants will: * Undergo standard cardiac surgery requiring CPB * Have echocardiographic assessments (TTE before and after surgery) * Have their recovery and outcomes monitored, including ICU and hospital stay, postoperative labs, and survival within 30 days
NCT07100509
This study retrospectively examines major vascular injuries that occurred during elective thoracic surgeries over a 10-year period at a single tertiary care center. Although these injuries are rare, they can lead to life-threatening complications. The study aims to determine how often these injuries happen, what causes them, and how they are managed during surgery. It also evaluates the role of preoperative imaging and planning, including cardiovascular surgery team involvement, in preventing or managing these events. The findings are intended to help improve surgical safety and guide future preventive strategies.

In spine surgery, it is important to try to minimize bleeding. In particular, spine surgery often involves inserting hardware into bone, and/or removing bone in the spine. Because the bone in the spine contains blood vessels, there can often be bleeding from the bone itself that is difficult to stop completely. One way to stop bone bleeding is through the use of wax-like materials, which plug the bleeding bone and act as a physical barrier to stop bleeding. One example is Ostene bone hemostasis material, which has the advantage of being "water soluble", meaning it will dissolve naturally over time. The purpose of this study is to evaluate how well Ostene does at decreasing bleeding, by using a recognized scale called the validated intraoperative bleeding severity scale, abbreviated as "VIBe". In this study, the investigators will record the bleeding severity throughout multiple time points in surgery using this scale, and then the investigators will compare the measurements to patients in the past who did not receive Ostene. Overall, this research will help measure how well Ostene decreases bleeding.

NCT03557905
The aim of this study will be to explore the clinical value of ultrasonic monitoring in the diagnosis of anesthesia-induced atelectasis, the assessment of the effects of lung recruitment, the best positive end-expiratory pressure (PEEP) after RM and in the detection of the point of lung re-collapse after RM in pediatric patients undergoing lengthy microsurgery operations using two levels of intraoperative FIO2 (0.5 VERSUS 0.3).
NCT05550181
To gain a better understanding of the epidemiology of intraoperative hypocapnia, in particular the associations of intraoperative hypocapnia with patient demographics, ventilator characteristics, and perioperative complications we will perform an individual patient-level meta-analysis of two recent randomized clinical trials of intraoperative ventilation, the 'PROtective Ventilation using High versus LOw PEEP trial' (PROVHILO), and the 'Protective intraoperative ventilation with higher versus lower levels of positive end-expiratory pressure in obese patients trial' (PROBESE).
NCT05136157
Pre-operative blood glucose (BG) concentrations in type 2 diabetic patients undergoing elective non-cardiac surgery; have an increased incidence of in-hospital morbidity for cardiopulmonary and infectious complications. Also, hyperglycemia is associated with increased production and impaired scavenging of oxygen reactive species, polymorph nuclear neutrophil dysfunction and decreased intracellular killing, resulting in poor wound healing and increased risk of infection. Thus, perioperative optimal glucose management contributes to reduced morbidity and mortality. Recommendations favor moderate levels of capillary blood glucose (CBG); maintaining it in the range of 140-180 mg/dl. Peri-operative doses of rapidly acting insulin for glycemic control could be done by the sliding scale or the bolus-infusion approaches. The sliding scale of insulin is commonly used to manage peri-operative hyper-glycaemia. It involves administering prescribed doses of insulin when the CBG is within determined ranges and withholding insulin when the CBG is within normal range. When used as a sole therapy; it results in under-insulinisation and thus hyper-glycaemia. The use of a dynamic insulin regimen like the intravenous bolus-infusion approach; allows adjusting the blood glucose level according to the insulin sensitivity of each patient, thus, better glucose control and less variations than the intermittent intravenous bolus of short-acting insulin in the sliding scale despite the same blood glucose target.
NCT05237700
Robotic assisted laparoscopic and laparoscopic gynecological, colon-rectal and urological surgical procedures require that patients be placed in steep Trendelenburg positioning with or without lithotomy on operating table. Steep Trendelenburg positioning is a variation of supine positioning in which the patient lies face up with the head and body tilted 250-450 downwards. In lithotomy position the legs are placed in stirrups and knees bent flexing the leg on the operating table. Lithotomy position can be graded in four levels according to what access the surgeon needs. The arms are tucked and padded parallel to the body, or the arms left on an arm board at an angel of less 900. Intraoperative peripheral nerve injury (IPNI) may follow incorrect positioning, inadequate fixation, or prolonged time in positioning. IPNI is defined as new (within 48 h) sensory and/or motor deficits and occurs following a combination of stretch, ischemia and/or compression during surgery and the injuries are either temporary or permanent. In a systematic review we found that IPNI was related to lithotomy positioning with steep Trendelenburg in upper and lower extremity and the incidence of IPNI ranges from 0.16% to 10 %. IPNI after patient positioning on operating table has been described to result in pain and other symptoms as numbness, weakness, and tingling. As demonstrated in our systematic review many of the patients with IPNI did not report pain, which also supported in a recent review. In addition, our systematic review showed that the symptoms appeared immediately after surgical procedures and usually subside within three months. The systematic review also demonstrates that a few patients continue to have pain or/and other symptoms of IPNI up to one year following the surgery. Furthermore, previous studies have demonstrated that pain intensity and duration of pain influence daily activities and quality of life negatively. Positioning of the patients on operating table is a teamwork where the operating room nurse (ORN) has a pivotal role in order to protect the patients from experiencing injuries due to e.g. nerve compression and compromised circulation. The purpose of this study is to increase the knowledge of IPNI related to positioning in patients undergoing robotic-assisted laparoscopic surgery and laparoscopic surgery. As IPNI is an unclear phenomenon that can be difficult to diagnose, we want to identify pain and other symptoms immediately after surgery that might have an impact on development of IPNI. Several studies have reported persistent pain after surgery like neuropathic pain and that neuropathic pain occur soon after nerve lesion. To get at a broader picture of IPNI we want to explore pain and other symptoms and to characterize how these symptoms might change, and to identify risk factors associated with IPNI. Therefore, the aims of the present study are: 1. Identify the incidence of IPNI up to 12 months after surgery. 2. Explore pain, other symptoms, physical function and quality of life up to 12 months after surgery. 3. Explore risk factors associated with IPNI. 4. Explore associations between IPNI and quality of life.

NCT00197353
This study aims to compare human subjects receiving epidural bupivacaine local anesthetic at different doses and concentrations and to assess the effect on vasodilatation (sympathectomy), sensory and motor block. The hypothesis is that the drug concentration is more important than drug dose in the determination of the extent and intensity of differential sympathetic, sensory and motor block following epidural local anesthetic.
