NCT ID: NCT03879395 Completed - Melanoma Stage Iv Clinical Trials

Surgery for Gastrointestinal Metastases of Malignant Melanoma - a Single Center Retrospective Cohort Study

Start date: January 1, 2010
Study type: Observational

The aim is to conduct a single centre retrospective study of all patients with stage IV melanoma that underwent surgery for metastases at Sahlgrenska University Hospital between 2010-01-01 and 2018-12-31. Pre- and postoperative data will be collected from digital medical records, the Swedish Cancer Registry, the Swedish Cause of Death Register as well as from the national Swedish cancer patient database (INCA). If needed, patient records will be collected from other hospitals. Results will be presented in written format as a summary and analysis of the characteristics of the cases operated on during the inclusion period. The aim is to identify predictive and prognostic factors for outcome and complications in the surgical treatment of stage IV metastatic melanoma.

NCT ID: NCT02977429 Recruiting - Abdominal Infection Clinical Trials

Evaluation of Pcv-aCO2 in the Fluid Treatment of Abdominal Tumor Patients After Surgery

Start date: October 2016
Phase: N/A
Study type: Interventional

This research will confirm that Pcv-aCO2 is suitable for the guidance of early fluid therapy and the evaluation of the prognosis of patients with abnormal hemodynamics after abdominal tumor surgery, and is expected to be a new monitoring index to improve the therapeutic effect of these patients.

NCT ID: NCT01669044 Recruiting - Cirrhosis Clinical Trials

Comparison the Hemodynamics Effects Between Dexmedetomidine and Propofol in Major Abdominal Surgical Patients

Start date: May 2012
Phase: N/A
Study type: Observational

The alpha2 agonist dexmedetomidine is a new sedative agent combined with the analgesic qualities and lack of respiratory depression. Patients sedated with dexmedetomidine could be easily roused, these advances shows dexmedetomidine may be a effective and safe sedative agent. But some studies showed some adversely effects of dexmedetomidine on haemodynamics (such as bradycardia, hypotension), the investigators want to further research the effects of dexmedetomidine on haemodynamics, such as Cardiac Output (CO), Systemic Venous Resistance Index(SVRI), and so on. Propofol is widely used sedative agent in ICU, it also has adversely effects like bradycardia and hypotension, so the investigators want to compare the effect of dexmedetomidine with propofol on haemodynamics after major abdominal surgery. Expect to further research the mechanism of haemodynamics of dexmedetomidine.
