NCT ID: NCT03749122 Completed - Surgery Clinical Trials

Time to Hip Fracture Surgery

Start date: January 1, 2006
Study type: Observational

The purpose of the study is to evaluate how time from hospital admission to start of surgery influence mortality in patients with acute hip fracture. Data on patients with hip fracture surgery will be collected from the hospital's registration system and will be analyzed regarding age, gender, American Society of Anesthesiologists (ASA) Physical Status Classification, type of surgery and time from admission to surgery along with data on mortality.

NCT ID: NCT03707015 Completed - Surgery Clinical Trials

Internal Limiting Membrane Flap in the Management of Retinal Detachment Due to Paracentral Retinal Breaks

Start date: January 2017
Study type: Observational

To describe the technique and outcomes of using either inverted or free internal limiting membrane flap in the management of retinal detachment due to paracentral retinal breaks.

NCT ID: NCT03688997 Completed - Surgery Clinical Trials

Knot Tying Surgical Simulator for Vessel Ligation

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

The investigators developed a bench-top knot tying simulator (KNOTI), with computer acquired assessment. Fifteen attending surgeons and 30 first year surgical residents were recruited to the study held at tertiary medical center during the years 2017-2018. The participants tied eight knots in different settings (Superficial vs. Deep) and techniques (One hand vs. two hands).

NCT ID: NCT03669328 Completed - Cancer Clinical Trials

Evaluation of Pain and Postoperative Nausea Vomiting Incidence in Outpatient Surgery at IUCT-Oncopole Hospital

Start date: June 1, 2016
Study type: Observational [Patient Registry]

The effectiveness of the analgesic and anti-nausea prevention techniques of the investigators justifies being evaluated regularly in order to adapt the management strategy to the specificities of each surgical act. A first evaluation took place in June 2016 and allowed to identify a category of patients (partial breast surgery with or without axillary gesture) not benefiting from an ideal algological management because justifying in 30% of the cases of a level 3 analgesic remedy in the postoperative recovery room. This use of morphine results in a significant incidence of postoperative nausea and prolonged recovery time before return home harmful to the patient. With their experience in locoregional anesthesia technique in complete breast surgery (total mastectomy) and aware of the effectiveness of this type of anesthesia on the management of immediate and chronic pain, the investigators have extended their indications of ALR to partial breast surgery in ambulatory.

NCT ID: NCT03646734 Completed - Surgery Clinical Trials

Guided Bone Regeneration With Particulate Versus Block Graft

Start date: January 10, 2017
Study type: Observational

The aim of present study was to compare two bone augmentation techniques (Guided Bone Regeneration, GBR, with autogenous block graft and GBR with particulate autograft plus xenograft) in terms of efficacy, complications, operational parameters (cost of the materials used, time for patient preparation, time for surgery, fatigue of the physician caused by surgery) tolerability by the patient and patient comfort.

NCT ID: NCT03638492 Completed - Melanoma Clinical Trials

Trial of Surgical Excision Margins in Thick Primary Melanoma - 2

Start date: January 1992
Phase: N/A
Study type: Interventional

Objectives: The purpose of this study was to assess the long-term follow-up of the overall and melanoma-specific survival in the randomised, open-lable multicenter trial (NTC NCT01183936) comparing excision margin of 2 cm versus 4 cm for patients with primary cutaneous malignant melanoma (CMM) thicker than 2 mm. Study hypothesis: The hypothesis is that there is no difference between the two treatment arms measured as melanoma-specific survival and overall survival.

NCT ID: NCT03627325 Completed - Surgery Clinical Trials

The Difference in Preoperative Evaluation That is Given by a Senior Physician, a Specialist, and a Computer Program

Start date: October 2, 2014
Study type: Observational

There is an increasing need and interest in being able to empirically estimate customized, patient-specific risks for virtually all surgical operations in a user-friendly format. The ACS (American College of Surgeons) surgical risk calculator is a decision-support tool based on reliable multi institutional clinical data, which can be used to estimate the risks of most operations.1 The aim of this study is to compare the assessment provided by the The ACS Surgical Risk Calculator with the assessment provided by a senior and a resident anesthesiologist, and by that comparison to establish the need for the ACS calculator

NCT ID: NCT03578692 Completed - Surgery Clinical Trials

Indicators Predicting Surgery in Acute Severe Ulcerative Colitis(ASUC)

Start date: January 1, 2012
Study type: Observational

Acute severe ulcerative colitis [ASUC] patients have high risk of no response to medical treatments and might miss the best timing for surgery when waiting for the medical response. Thus, we investigated whether biomarkers which could early predict the surgery risk of patients with ASUC on admission.

NCT ID: NCT03547401 Completed - Surgery Clinical Trials

Ankle/Brachial Non-Invasive Blood Pressure Difference During General Anesthesia

Start date: August 1, 2018
Study type: Observational

Brachial non-invasive blood pressure (NIBP) monitoring is recommended as part of the American Society of Anesthesiology (ASA) basic monitoring package. Although brachial NIBP is often practical, some surgeries and patients may require NIBP measurement elsewhere (e.g. the ankle). Several studies have shown that ankle NIBP overestimates brachial NIBP measurements. Algorithms have been proposed, based on correlation studies, to estimate brachial NIBP from ankle NIBP during general anesthesia and mechanical ventilation. These algorithms, however, are based on both heterogeneous populations and surgeries. Our aim was to determine if ankle brachial NIBP difference occurs in in young ASA physical status 1 patients undergoing general anesthesia in the supine position. We also aim to determine if this difference is constant during anesthesia or if it varies according to different predefined time points.

NCT ID: NCT03476707 Completed - Anemia Clinical Trials

Association of Anemia With Hospital Costs in Elective Colorectal Surgery

Start date: January 2010
Study type: Observational

The objective is to measure the adjusted association between preoperative anemia and total hospital costs. We hypothesize that patients with anemia before surgery will have higher hospitalization costs than people without anemia.
