R³ Rehab Pathway Versus Usual Care After Lumbar Radicular Surgery
The R³ trial is a multicentre cluster randomized controlled trial evaluating an evidence-based, person-centred rehabilitation pathway for patients undergoing lumbar surgery for radicular pain. The pathway includes structured pre-, peri-, and postoperative rehabilitation, early postoperative mobilization, case management, early return-to-work (RTW) guidance, and patient empowerment. Clusters (hospitals) are randomized to …
Optic Nerve Sheath Diameter and Cognitive Outcomes in Bentall Surgery
Bentall surgery is a major cardiac procedure involving replacement of the ascending aorta, aortic root, and aortic valve, typically requiring cardiopulmonary bypass (CPB) and sometimes deep hypothermic circulatory arrest (DHCA). Due to its complexity, it carries a significant risk of postoperative neurological complications including stroke and postoperative cognitive dysfunction (POCD). …
Mother and Offspring's Nutritional Status -Pregnancy After Maternal Bariatric Surgery
The goal of this observational study is to learn how bariatric surgery affects the health and nutritional status of women and their babies during pregnancy and after birth. The study will also investigate pregnancy complications and whether the time between surgery and pregnancy affects pregnancy outcomes. The study includes pregnant …
VC-AF vs FCV in Obese Patients Undergoing Laparoscopic Surgery
Obesity adversely affects respiratory physiology by reducing lung volumes and compliance and increasing airway resistance and alveolar collapse. These effects are further aggravated by pneumoperitoneum during laparoscopic surgery, increasing the risk of impaired oxygenation and ventilator-induced lung injury (VILI). Mechanical power (MP) reflects the total energy transferred to the respiratory …
BMI-Adjusted PEEP During One-Lung Ventilation in Thoracic Surgery
One-lung ventilation (OLV) is required during many thoracic surgical procedures and is associated with reduced functional residual capacity, atelectasis, ventilation-perfusion mismatch, hypoxemia, and potentially ventilator-induced lung injury. Lung-protective ventilation strategies include low tidal volumes, limitation of airway pressures, and positive end-expiratory pressure (PEEP), but the optimal PEEP level during OLV …
Efficacy of Gastrocnemius Plane Block for Foot and Ankle Surgery
The study aim is to evaluate the efficacy of the gastrocnemius plane block (GPB) in providing postoperative analgesia for patients undergoing foot and ankle surgery. Objectives To evaluate the duration of postoperative analgesia provided by the gastrocnemius plane block To assess postoperative opioid or rescue analgesic consumption within the first …
Pulmonary Mechanics and Cerebral Oxygenation During Prone Lumbar Disc Surgery
This prospective observational study aims to evaluate the relationship between changes in respiratory mechanics and cerebral oxygenation in adult patients undergoing elective lumbar disc surgery in the prone position under general anesthesia. Cerebral regional oxygen saturation will be monitored using bilateral frontal near-infrared spectroscopy (NIRS), while respiratory parameters including tidal …
Effect of a Constipation Prevention Checklist in Hip Surgery Patients
Constipation is a common postoperative problem in patients undergoing hip surgery and may be associated with immobilization, opioid analgesic use, and inadequate fluid and fiber intake. Preventive interventions, including adequate fluid and nutritional intake, early mobilization, and abdominal massage, may help maintain bowel function. However, evidence regarding the effectiveness of …
The Effect of Radiotherapy After Separation Surgery for Spinal Metastases
The aim of this clinical study is to explore the impact of whether radiotherapy is administered after spinal metastasis surgery on the prognosis and survival of patients, to describe the clinical outcomes, and to optimize future clinical decisions.
Postoperative Analgesic Effectiveness of Fascial Plane Blocks in Breast Surgery
This prospective, single-center observational study will compare postoperative pain control in adults undergoing elective breast surgery. Ninety participants will be evaluated in three groups based on routine clinical care: rhomboid intercostal plane block, serratus posterior superior intercostal plane block, and control. The anesthesia method and fascial plane block will be …
