Virtual Reality for Postoperative Recovery After Major Abdominal Surgery

Major abdominal surgery often leads to significant postoperative pain, anxiety, and prolonged hospital stays, which can delay overall recovery. This study aims to evaluate the effectiveness of immersive Virtual Reality (VR) as a non-pharmacological intervention to enhance the quality of recovery and reduce the length of hospital stay. Patients in the intervention group will engage in standardized VR sessions featuring guided relaxation and mindfulness-based stress reduction, starting from the evening before surgery through the third postoperative day. The study compares this VR-enhanced protocol against standard perioperative care within an Enhanced Recovery After Surgery (ERAS) framework. The findings are expected to determine if VR can serve as a feasible and effective tool to improve clinical outcomes and patient well-being in surgical wards.

The PRIMROSE Trial

Smoking is a major cause for developing lung cancer. People diagnosed with lung cancer, may be offered surgery which offers a complete cure. Smoking also damages the lungs and compromises a person's lung function, resulting in shortness of breath. Breathlessness limits the ability to carry out daily physical activities and exercise and makes people vulnerable to developing post procedure complications and even death. Some people with surgically treatable lung cancer have a poor ability to exercise and compromised lung function and are not fit for surgery. They will instead be referred for radiation therapy, chemotherapy or palliative care. Surgery is the preferred treatment option. The pulmonary rehabilitation program (Prehab) improves fitness levels. In addition, it improves the level of breathlessness, exercise capacity and vulnerability of people with lung cancer, with the aim of making them fit for safe surgery. By adding a breathing training device to the Prehab program, the investigators aim to further improve participants fitness for surgery, lower their risk of developing complications and the time spent in hospital after the procedure. The breathing training device is called an inspiratory muscle training device. The hand-held device helps to train and strengthen the breathing muscles, which are then able to work more effectively. After the procedure, participants may be able to breathe and exercise more easily reducing their risk of developing complications and improving outcomes. The study will compare two groups of people with lung cancer having surgical removal of part of the lung, at a specialist hospital . One group will receive standard Prehab and inspiratory muscle training with the device prior to the procedure; patients in the second group with receive standard Prehab prior to the procedure. Participants will be followed up for twelve months.

Opioid Consumption After Thoracotomy and Factors Affecting Postoperative Acute Pain

Thoracic surgery operations constitute a significant portion of surgical procedures performed in hospitals. In the United States, more than 50,000 thoracic surgical procedures are performed annually, and more than 80% of these patients experience moderate to severe postoperative pain requiring opioid administration, which increases the risk of complications . It has also been reported that chronic pain develops in approximately 50% of patients after thoracic surgery . Thoracic surgery is commonly associated with severe, multifactorial pain during the postoperative period and is among the surgical branches with a high risk of developing chronic pain Despite advances in understanding postoperative pain mechanisms and improvements in pain management, inadequate postoperative pain control remains an unresolved healthcare problem. Higher acute pain scores are associated with less effective ventilation and coughing, increased incidence of lower respiratory tract infections, and prolonged ICU and hospital stays . In the management of acute postoperative pain after thoracic surgery, clinicians have sought alternatives to thoracic epidural analgesia to avoid its potential adverse effects. Truncal blocks such as thoracic paravertebral block, erector spinae plane block, and serratus anterior block have been used to reduce postoperative pain . Additionally, various other analgesic techniques such as patient-controlled analgesia (PCA) and multimodal analgesia have been employed. Historically, the cornerstone of acute postoperative pain control has been systemic opioids administered via oral, intravenous, or thoracic epidural routes . Although opioids provide excellent pain relief, they are associated with significant side effects that can adversely affect recovery . With the increasing use of ultrasonography (USG), truncal blocks have become more widespread. Alongside the development of Enhanced Recovery After Thoracic Surgery (ERATS) protocols, efforts have been made to reduce opioid use, leading to differing opinions regarding the management of acute pain after thoracic surgery. To prevent opioid use disorder and potential side effects, opioid-free or opioid-sparing approaches are now being encouraged in perioperative pain management . Conversely, some studies suggest that intraoperative opioid administration may have favorable effects on postoperative acute and chronic pain. Previous research has reported that the average daily opioid consumption after thoracic surgery is approximately 30 morphine milligram equivalents (MME) . Although video-assisted thoracoscopic surgery (VATS) has become more common, thoracotomy cases still constitute a large proportion of thoracic surgery procedures. Moreover, severe postoperative pain after thoracic surgery is most commonly associated with the thoracotomy incision itself. While some studies have suggested that new truncal block techniques may provide effective analgesia and reduce opioid consumption after thoracotomy, further studies are needed to determine which blocks are most commonly preferred and how opioid consumption patterns have changed with the adoption of these newer regional techniques. A review of the current literature reveals that the factors influencing acute pain after thoracotomy have not been sufficiently evaluated. Therefore, a re-evaluation of the factors affecting acute pain following thoracotomy, considering recent developments in pain management, is necessary. Furthermore, examining the relationship between perioperative opioid consumption, postoperative complications, and hospital length of stay in this patient population will provide valuable contributions to the literature. The aim of this study is to evaluate the amount of opioid consumption following thoracotomy and to investigate whether perioperative opioid use affects acute pain, postoperative complications, and the length of hospital stay.

Preoperative Coadministration of Low-concentration Carbohydrate and Nitrates Loading vs Low- Concentration Carbohydrate Loading Alone in Patients Undergoing Open Gynecological Surgeries

Surgery is known to be associated with stress response affecting in a negative way the clinical outcome and patient experience. The stress response includes both sympathetic nervous system activation and systemic inflammatory response. The pituitary- sympathetic one leads to a number of metabolic changes as hyperglycemia, nitrogen loss and lipolysis on the other hand the systemic inflammatory response aggravates the perioperative metabolic changes. One of components of ERAS is preoperative carbohydrate load. Oral carbohydrate was associated with attenuation of the postoperative metabolic stress response. Nitrate rich drinks before exercises have a promising impact due to improving blood flow, mitochondrial efficiency, glucose uptake and the sarcoplasmic calcium handling all of which maximize resistance to fatigue and improved exercise performance.

Enhanced Recovery After Surgery (ERAS) Pathway in Patients Undergoing Robot-Assisted Laparoscopic Radical Prostatectomy

Prostate cancer ranks second among all malignances in men and has become a significant threat to men's health. Robot-assisted laparoscopic radical prostatectomy (RARP) has become a standard treatment for prostate cancer. How to improve recovery following RARP surgery is worth investigating. The enhanced recovery after surgery (ERAS) pathway involves a series of evidence-based procedures. It is aimed to reduce the systemic stress response to surgery and shorten the length of hospital stay. This randomized trial aims to investigate the impact of Enhanced Recovery After Surgery (ERAS) Pathway on early outcomes after RARP surgery.

The Effect of Perioperative Nutritional Care on Recovery After Knee and Hip Replacement Surgery

This prospective observational study will assess the impact of standardized perioperative nutritional care on postoperative outcomes in patients undergoing elective total hip (THA) or knee arthroplasty (TKA) at the First Department of Orthopaedic Surgery, St. Anne's University Hospital in Brno. The protocol includes preoperative patient education, nutritional risk screening, and carbohydrate loading up to two hours before anesthesia, followed by early postoperative refeeding. Data collection will include demographic and surgical variables, nutritional status, carbohydrate intake, and the occurrence of intra- and postoperative complications, including infection and delayed wound healing. As perioperative nutritional care is part of routine clinical practice, the study requires no additional interventions or resources. Results will provide evidence on the effectiveness of structured nutritional support in enhancing recovery and reducing complications after joint replacement surgery.

Patient Control Epidural Versus Conventional Epidural.

As one of the complications of THR is post operative pain, which usually requires epidural catheter insertion. We are comparing the effect of patient control epidural versus conventional epidural for patient's satisfaction.

VCare Versus SecuFix Uterine Manipulator for Total Laparoscopic Hysterectomy

Hysterectomy, the most commonly performed gynecological operation, can be carried out through various methods using a wide array of instruments and energy techniques. Minimally invasive procedures such as robotic or laparoscopic approaches are linked to lower perioperative complications and quicker recovery when compared to abdominal hysterectomy. Furthermore, recent advancements in surgical tools and methodologies have facilitated endoscopic surgeries. Uterine manipulation plays a crucial role in laparoscopic hysterectomy by facilitating bladder dissection, positioning the ureters, and exposing the anterior and posterior vaginal fornices. It also prevents pneumoperitoneum loss by closing off the vaginal space. Despite these apparent benefits, there is no existing report comparing different types of uterine manipulators. Therefore, the purpose of this study was to compare the Vcare and SecuFix uterine manipulators used in laparoscopic hysterectomy based on operative time, length of hospital stay, estimated blood loss, perioperative complications, and subjective performance.
