NCT ID: NCT06378710 Recruiting - Surgery Clinical Trials

Haemodynamic and Respiratory Effects of a Low Positive End Expiratory Pressure Associated With a Fluid Challenge in Knee-chest Position

OPTIPEP
Start date: January 20, 2023
Phase: N/A
Study type: Interventional

The genu pectoral position is a surgical position used for spine surgery. This surgical position will lead to physiological hemodynamic and respiratory changes during the procedure. The knee-pectoral position notably induces an increase in CRF and improves pulmonary ventilation/perfusion ratios. On the other hand, it has been shown that it is accompanied by a reduction in cardiac output of approximately 15% Protective perioperative ventilation including a tidal volume between 6 and 8 ml/kg of theoretical ideal weight, PEEP and alveolar recruitment maneuvers is applied in the operating room to reduce postoperative pulmonary complications. The application of high PEEP and the performance of recruitment maneuvers induce arterial hypotension through changes in intra- and transpulmonary pressures. However, investigators hypothesize that the deleterious hemodynamic effects of PEEP seem to counterbalance its beneficial respiratory effects in this particular position. The combination of the effects of the knee-pectoral position and protective ventilation could be potentiated and be the cause of the sometimes severe arterial hypotension observed in clinical practice. Since this position improves pulmonary ventilation perfusion ratios, the investigators hypothesized that a lower PEEP and the elimination of intraoperative recruitment maneuvers could be beneficial from a hemodynamic point of view without being deleterious in terms of perioperative pulmonary complications. An exploratory study was carried out at the CAEN University Hospital in 2021 under the name PEEP POSTURE (CLERS Agreement No. 2198 of February 17, 2021) on 90 patients aiming to collect hemodynamic and respiratory parameters in 3 surgical positions: supine decubitus, ventral decubitus , pectoral genu. No difference was found in the evolution of respiratory compliance. On the other hand, a significant drop in SBP, DBP and MAP in the pectoral position was shown compared to the supine group as well as greater vascular filling. The investigators therefore hypothesize that a reduction in PEEP and optimization of vascular filling could help reduce the adverse effects on blood pressure linked to the surgical position.

Monitoring of Lung Ventilation Through Electrical Impedance Tomography During Pediatric Surgery

VentiPed
Start date: April 15, 2024
Phase:
Study type: Observational [Patient Registry]

Given the scarcity of studies aimed at assessing the effect of anesthesia and m ventilation on the distribution of lung ventilation in pediatric patients undergoing surgery, with the exclusion of thoracic surgery, the present prospective observational study would shed the light on ventilation practice in pediatric anesthesia for surgery. This study wold fill the actual gap allowing the evaluation, through electrical impedance tomography (EIT) of the distribution of lung ventilation across the different phases of anesthesia for pediatric surgery. These insights could contribute to improve clinical practice and research in the management of ventilation in pediatric patients undergoing anesthesia for surgery.

Mini-invasive Spine Surgery for Neuromuscolar Scoliosis

MISNM
Start date: May 2024
Phase: N/A
Study type: Interventional

Neuromuscular scoliosis (SNM) are deformities related to the impairment of normal function of the central nervous system (CNS) and/or peripheral nervous system (PNS) resulting in alterations to the of the functional unit represented by the integrated motor sequence (SIM). At the level of the spine, dysfunction of the SIM results in altered dynamic support of the spine. This results in a control of the trunk that is not harmonious due to the lack of effective mechanisms of muscle compensation. In particular, a greater degree of pelvic tilt with respect to the ground plane, with an increase in the degree of the so-called pelvic obliquity (OP), a fundamental parameter in walking and maintaining the seated posture. Spinal deformity causes severe alterations of the rib cage resulting in respiratory failure that often requires ventilatory supports and is associated with frequent airway infections, including pneumonias, often fatal. SNMs also express other comorbidities: cardiac (heart failure), neurological (epilepsy), nutritional that necessitate careful management multidisciplinary and especially anesthesiological evaluation for the peri-operative management. The surgical treatment of SNM constitutes a topic that is still debated due to both the bio-mechanical peculiarities of SNM and the clinical features, particularly comorbidities, that characterize this patient population. Compared with idiopathic scoliosis surgery, in SNM there is a higher rate of complications. To date, most of the complications are respiratory in nature (23%), followed by complications mechanical of the implanted surgical instrumentation (13%), and surgical site infections (11%). Furthermore, there is evidence that SNM surgery correlates with increased blood loss intraoperative. To date, it is recognized in the literature that the safest and most effective surgical treatment for SNMs is arthrodesis posterior instrumented with pedicle screws extended to the pelvis. In the years, mini-invasive surgical techniques have become increasingly prominent. invasive with the goal of reducing operative time, blood loss and complications themselves.

Single- vs Two-staged Excisions of Thin Melanoma

WvW
Start date: October 1, 2024
Phase: N/A
Study type: Interventional

The overall aim of this national, multicenter, prospective, randomized, and controlled study is to enhance the management of patients with thin melanoma (≤1 mm Breslow thickness). The investigators hypothesize that wide local excisions (WLEs) following complete excision of thin melanoma do not affect the risk of recurrence, defined as the occurrence of local, regional, distant disease, or melanoma-specific death during a 5- to 10-year follow-up period.

NCT ID: NCT06363175 Not yet recruiting - Surgery Clinical Trials

PREMs In Vascular SurgERy Enhancement Study

PREMIERE
Start date: June 1, 2024
Phase:
Study type: Observational

THE PROBLEM: Patient Reported Experience Measures (PREMs) ask patients about their healthcare service experience. It gives them a voice to share their views. PREMs allow healthcare providers (HCPs) to see where care is good, and where they could improve. Vascular surgery is a surgical speciality looking after people's blood vessels (arteries and veins). There is no PREM available for vascular patients. The research team want to create a PREM for this patient group. WHY IT IS IMPORTANT: A PREM allows HCPs to record and understand patients' experiences of their treatment. It gives patients a way to provide feedback on their healthcare experience. PREMs can help HCPs make changes to patients' care, identifying areas of good practice and areas for improvement. The Welsh Government is keen to support the use of PREMs. AIMS: To develop a PREM specific to vascular surgery patients. RESEARCH PLAN: The research team will summarise the literature about PREMs in surgery. The research team will then run focus groups and interviews with patients and staff to create a 'draft' PREM for vascular patients in Wales. The 'draft' PREM will be translated into Welsh. In the second phase, a larger number of vascular patients (100-300 depending on how long the 'draft' PREM is) from hospitals across Wales will complete the questionnaire. Statistical tests will look at the results to see if the questionnaire works well to capture patients' experiences. Based on these results, small changes will be made to make the 'draft' PREM better. This will make sure the 'final PREM' is ready for widespread use in Wales and beyond. PATIENT AND PUBLIC INVOLVEMENT: The patients' experience team at CAVUHB has reviewed our patients' materials. Our research team includes PPI co-applicants (DC and AH). DC a double amputee who has had many vascular operations. DC has experience raising awareness about vascular disease through public forums like the Limbless Association Charity and BBC Radio Wales. AH has issues with her leg due to smoking and had a keyhole operation to help with that. She had some problems after the procedure This is her first time as a PPI representative. DC and AH supported our research design and will be steering group members. Also, our research focuses on giving patients a voice and will include patients across Wales. A diverse group of patients will be involved across all stages of the PREM development.
