Clinical trials

This prospective, randomized, assessor-blinded clinical trial aims to compare the postoperative analgesic efficacy of ultrasound-guided Erector Spinae Plane Block (ESPB) and Modified External Oblique Intercostal Plane Block (EOIPB) in patients undergoing elective open nephrectomy under general anesthesia. Sixty adult patients will be randomized to receive either ESPB or EOIPB before surgical incision. All participants will receive standardized general anesthesia and postoperative multimodal analgesia. Postoperative pain scores, opioid consumption, rescue analgesic requirements, and postoperative nausea and vomiting will be assessed during the first 24 hours after surgery. The study aims to determine whether one fascial plane block technique provides superior postoperative pain control and recovery following open nephrectomy.

The goal of this clinical study is to compare two surgical techniques used for the treatment of complex Peyronie's disease. Peyronie's disease can cause penile curvature, deformity, and difficulties during sexual intercourse due to fibrotic plaques within the penile tunica albuginea. In patients with severe deformity, surgical correction is often required. The main question this study aims to answer is whether subtunical microdissection can provide effective correction of penile curvature while preserving erectile function when compared with the classical plaque incision and grafting technique. Participants with complex Peyronie's disease who require surgical correction will undergo either subtunical microdissection or classical plaque incision and grafting. In order to standardize the procedures, the same graft material will be used in both surgical techniques. A bovine pericardial graft will be applied in all cases, and graft size will be determined according to the geometric principles described by Egydio. In the subtunical microdissection technique, the subtunical plane beneath the Peyronie's plaque is carefully dissected using microsurgical instruments under approximately 3.5× optical magnification with surgical loupes. In the classical technique, plaque incision is performed followed by graft reconstruction of the tunical defect. All surgical procedures will be performed by the same surgical team using a standardized operative approach and a uniform anesthesia protocol. Participants will be followed prospectively after surgery to evaluate penile curvature, erectile function, and patient satisfaction. The results of this study may help determine whether subtunical microdissection represents an effective and safe alternative surgical strategy for the treatment of complex Peyronie's disease.

This study aims to compare the efficacy and safety, the ratio of stone-free rates, and complications of two types of access sheaths used in retrograde intrarenal surgery to treat upper urothelial stones. The access sheath types are those with vacuum aspiration and the conventional ones.

Kidney stone disease is a common condition, and retrograde intrarenal surgery (RIRS) is a minimally invasive procedure frequently used to remove kidney stones. During RIRS, pressure inside the kidney can increase, which may contribute to temporary kidney injury. New aspiration-enabled access sheath systems have been developed to better control this pressure by continuously removing irrigation fluid during surgery. This study will compare aspiration and conventional access sheath systems to determine whether improved pressure control reduces early kidney injury. Blood and urine biomarkers (IL-18 and L-FABP), which can detect kidney damage earlier than standard kidney function tests, will be measured before and after surgery. The results may help identify surgical techniques that better protect kidney function and improve the safety of kidney stone treatment for patients.

In order to prevent sarcopenia in intensive care patients and to guide nutritional therapy, evaluation of muscle thickness with ultrasonography is a modern, simple and non-invasive procedure routinely performed by Anesthesiology and Reanimation specialists. Sarcopenia in intensive care patients has been demonstrated in many studies. It has been studied that routine examination of changes in rectus femoris muscle thickness by ultrasonography is a predictor of sarcopenia. However, the muscles in the neck region, such as the sternocleidomastoid muscle, which are easy to examine, have not been studied very well. There is no study in the literature with the sternocleidomastoid muscle. For this reason, we decided to examine the relationship of sternocleidomastoid muscle thickness with patient characteristics, treatments, feeding route and type, feeding time, length of stay in intensive care unit, as in routine measurements of rectus femoris muscle thickness by ultrasonography.

The results of combining infiltrative analgesia applied by orthopedists with epidural analgesia applied by anesthesiologists after knee replacement surgery will be compared. It aims to compare epidural analgesia with the maximum reduction of postoperative pain in patients, as well as in terms of both analgesic and complications. The study will include patients who have undergone knee replacement surgery for six months. In the study, we will compare the results of painkillers applied to the patient from the waist or knee after the waist numbing anesthesia, which includes some of the routinely applied protocols of your knee replacement surgery. It is a condition that will be monitored after surgery. The study aims to reduce maximum pain with two painkiller methods applied in small amounts or together. No interventional application will be made to the patient who will undergo surgery other than routine application. After the surgery, you will be asked verbally about your pain level and side effects at certain hours after the surgery and the amount of painkillers used and the amount of painkillers will be determined according to the follow-up hours (1st, 2nd, 6th, 12th, 24th and 48th hours after the surgery). In addition to these, complications will also be monitored. The results of patients who can be fully followed up at the end of 6 months will be presented as a scientific study.

The rate of complications (unexpected situations) after retrograde intrarenal surgery is reported to be 9-25%, and the majority of these are postoperative infections. Surgery must be performed under sterile (microbial-free) urine culture to prevent these complications. There are guideline recommendations regarding sterile urine culture reporting, but it is not clear how long in advance it should be taken. The possibility of the patient becoming infectious again during the period leading up to surgery is a condition that needs to be determined. Therefore, the culture taken before surgery should be compared with the urine culture result taken at the latest possible time before the operation.

Babies born before the thirty-seventh gestational week are called preterm or premature. Most preterm newborns require Neonatal Intensive Care Unit (NICU) care depending on their gestational age and clinical condition. Although many painful invasive procedures are usually performed on newborns in the NICU, the most common procedure is heel prick. Heel prick is a painful and stressful procedure for the newborn. Neonates do not respond to pain verbally; they respond physiologically, behaviorally and hormonally. Physiologic responses of preterm infants to pain include increased heart and respiratory rate, increased blood pressure and intracranial pressure, decreased oxygenation, and sweating of palms. Among the hormonal symptoms caused by stress in newborns, the most commonly used biochemical method is the measurement of cortisol level. It is reported that there is a significant correlation between salivary and plasma cortisol levels and salivary cortisol level reflects plasma cortisol level. This method is particularly preferred because saliva sampling is much less stressful.

The aim of this observational study is to learn the effects of hormone therapy (testosterone) applied in micropenis hypospadias surgery on the depth of anesthesia under general anesthesia. The main question it aims to answer is: The effect of testosterone therapy on the depth of general anesthesia. Based on these, to comment on the depth of anesthesia of patients who have just started using testosterone for sex change. To follow the depth of anesthesia of patients who have undergone hypospadias surgery with BIS monitoring and to record respiratory parameters under general anesthesia.
