Active clinical trials for "Postoperative Complications"

This phase II trial studies bioimpedance spectroscopy in detecting lower-extremity lymphedema in patients with stage I, stage II, stage III, or stage IV vulvar cancer undergoing surgery and lymphadenectomy. Diagnostic procedures, such as bioimpedance spectroscopy, may help doctors to predict the onset of lower-extremity lymphedema in patients with vulvar cancer undergoing surgery.

Central venous catheterization is commonly applied in patients undergoing cardiac surgery. The subclavian vein has lower risk of infection and provides more patients comfort. However central venous catheterization may results in complications such as pneumothorax, hemothorax or arterial puncture. It has been suggested that ultrasound (US) guidance could improve the success rate, reduce the number of needle passes and decrease complications. Two different real-time 2-dimensional US techniques can be employed in the insertion of central venous catheters. The first technique involves real-time US-guided cannulation of subclavian vein using a long axis/in-plane approach. The second one involves real-time US-guided using a short axis/out-off-plane approach. However to date no studies have compared their efficacy and safety. The purpose of this study was to compare the US-guided long-axis versus short-axis approach for the SCV catheterization in adult critical care patients.

RATIONALE: An anal sphincter prosthesis may replace the need for a permanent colostomy and may improve the quality of life of patients who are undergoing surgery for anal or rectal cancer. PURPOSE: Clinical trial to study the effectiveness of an anal sphincter prosthesis in treating patients who have anal or rectal cancer and are undergoing surgery to remove the anus and rectum.

This is the first multiple-dose experience in humans with MOA-728 in an oral formulation. This study will provide an assessment of the safety, tolerability, and pharmacokinetics (PK) of MOA-728 following administration of ascending multiple oral doses to healthy subjects.

RATIONALE: The use of pelvic drains may help to prevent complications following radical hysterectomy and pelvic lymphadenectomy. It is not known whether receiving pelvic drains during surgery is more effective than receiving no pelvic drains during surgery in patients with uterine, cervical, or vaginal cancer. PURPOSE: Randomized phase III trial to determine if the use of pelvic drains following radical hysterectomy and pelvic lymphadenectomy is effective in treating patients with uterine, cervical, or vaginal cancer.

To assess and improve the safety and success rate of vascular puncture and catheterization using ultrasound-guided methods.

Traditionally, pain relief through spinal cord stimulation has been associated with the appearance of paresthesia in the affected area. Several parameters are set to maximize the overexposure zone, such as frequency,and pulse width. Although this technique has improved pain in many patients, paresthesia itself can be uncomfortable. Traditionally, the occurrence of paresthesias has been considered to be a predictor of success in pain elimination, while the non-occurrence of paresthesias would indicate failure. So far, few studies have reported pain relief below the threshold of onset of paresthesia. Some clinical trials for pathologies other than the one considered in this study have achieved relief below the threshold by reducing the amplitude of the stimulus. Recently, however, it has been observed in a pilot study that, by increasing the frequency of spinal cord stimulation to 1 kilohertz, it is possible to significantly improve pain relief compared to less frequent conventional stimulation based on the occurrence of paresthesias. A recent review by the Cochrane Library concluded that conventional spinal cord stimulation for pain relief of Failed Back Surgery Syndrome (or FBSS) requires further clinical studies and better designs to demonstrate its superiority over other therapeutic options. Therefore, although spinal cord stimulation is accepted by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA), new techniques are being introduced that offer better results in terms of pain relief. Among these techniques, there is the high frequency mode, which allows avoiding the annoying sensation of paresthesia that substitutes pain with the conventional technique. In order to provide greater rigour and scientific quality, the present study is proposed, in which the conventional spinal cord stimulation (CME) technique (control branch or CME) is compared with paresthesias and a standard frequency (60 hertz) with a high frequency (1000 hertz) EVOLVE system (Evolve workflow - standardized guidance to simplify the trial and implant experience and optimize patient outcomes) (experimental branch or EME) by means of a design with a high degree of scientific evidence, randomising the global sample of patients to each of the two branches of stimulation in the study (blind to the patient) and crossing the branches after a period of washing

INTRODUCTION: The aim of this study was to investigate the effects of tranversus abdominis plane (TAP) block placed postoperatively using ultrasound guidance for patients with caesarean section, myomectomy and hysterectomy under general anesthesia by eliminating additional pain caused by surgical incision. MATERIALS AND METHODS: The study has been planned to investigate the postoperative analgesia of 50 patients with TAP blocks applied and non-applied between the ages of 18-65, who will pass abdominal surgery. Study has been conducted in a prospective, randomized and controlled manner. Patients have been classified as those who have undergone TAP block (group: I) and those without block (group: II).

In this study, it was aimed to determine the effect of HRU and HG on patient outcomes in the care process in surgical patients followed according to MEUSS. The sample of the study, which was conducted as a randomized-controlled clinical trial, consisted of 252 patients who underwent surgical intervention under general anesthesia in a university hospital between 29 July 2022 and 31 October 2022.

This prospective nonrandomized multicenter phase I study, will evaluate the feasibility of performing uterine transposition before chemoradiation for rectal cancer and uterine reimplantation after the treatment.
