Filter by:The purpose of the study is to test whether colloid-based goal-directed intraoperative fluid management leads to less perioperative morbidity compared to crystalloid-based goal-directed intraoperative fluid management. Goal-directed therapy is based on measurements by an Esophageal Doppler Device.
Geriatric patients have a high risk of developing postoperative cognitive deficits. Hypothetical causes are insufficient intraoperative cerebral perfusion or drugs that are administered in the perioperative setting. This study will investigate the role of these two factors in patients aged 65 or older undergoing elective surgical procedures under general aesthesia. Non-invasive techniques will be used to monitor intraoperative cerebral perfusion and anticholinergic activity in the patient's blood is determined. Data will be compared to those of a young (20-40 year old) group of patients undergoing elective surgical procedures using an identical anesthetic technique. A second control group of healthy volunteers older than 65 will be investigated to quantify practice effects with repeated testing of cognitive functions.
To discover whether an Omega-3 fatty acid (eicosapentaenoic acid/EPA and docosahexaensyre/DHA) enriched nutritional supplement given 7 days preoperatively and 7 days postoperatively may reduce the frequency of postoperative infectious complications defined as: pneumonia, wound infection, urinary tract infection, peritonitis (including anastomotic leakage) and septic conditions of any cause in patients who undergo elective operations for colorectal cancer compared with a nutritional preparation that is identical apart from the EPA content.
The purpose of this study is to determine whether drainage after prosthetic repair of incisional abdominal hernias increases or decreases complications such as infection, seromas and hematomas.
The aim of this study is to increase the detection of undiagnosed obstructive sleep apnea (OSA) and secondly to increase the sensitivity for detection of respiratory depression (< 6 breaths per minute) in post operative patients on the general care nursing unit.
The aim of the present study is to compare the functional and clinical differences and advantages between a standard operating system and a newly developed even smaller system for pars plana vitrectomy. The present study may work out the possible advantages and disadvantages between the routinely used 20-gauge vitrectomy system and the newly developed 23-gauge device.
The objective of this study is to prospectively estimate the all-cause complication rates at 6-months for patients undergoing generator replacement due to elective replacement indicator (ERI), advisory, or upgrade without a planned system modification or with a planned system modification. Secondarily, this study aims to compare the influence of baseline variables contributing to the all-cause complication rates for subjects undergoing generator replacement.
RATIONALE: Exercise may help improve lung function and lessen complications of surgery in patients with chronic obstructive pulmonary disease who are undergoing surgery for lung cancer. It is not yet known whether lung rehabilitation is more effective than standard therapy in improving lung function in patients with chronic obstructive pulmonary disease who are undergoing surgery for lung cancer. PURPOSE: This randomized clinical trial is studying lung rehabilitation to see how well it works compared to standard therapy in treating patients with chronic obstructive pulmonary disease who are undergoing surgery for lung cancer.
Superior sulcus deformity in post-enucleation socket syndrome (PESS) may pose a significant cosmetic blemish after enucleation surgery despite apparently adequate orbital volume replacement. The underlying reasons include the lack of accurate pre-operative volumetric assessment of the anophthalmic socket, leading to either under or over estimation of the orbital implant required and the shifting in orbital and periocular structures that may occur post enucleation. Conventional imaging studies (computed tomography and magnetic resonance imaging) have been used to study the anatomy of anophthalmic sockets, but there are several drawbacks such as poor image quality for detailed volumetric assessment, long exposure time with possible motion artifact and etc. The new multi-detector computed tomographic technology is the latest advance in diagnostic radiology that allows rapid high resolution images to be obtained for three dimensional reconstruction and volumetric assessment. This new imaging modality will contribute greatly to the understanding of PESS and the surgical planning of anophthalmic sockets reconstruction. This is a pilot study aiming to collect clinical data on the volumetric and structural changes in PESS. The information obtained will: 1. allow more accurate volume estimation of the primary orbital implants prior to enucleation surgeries, thus minimize the development of PESS; 2. evaluate the volumetric & structural anomalies that constitute PESS 3. be used for the development of a new customized secondary orbital implant to manage superior sulcus deformity in PESS.
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.
