Comparison of Extubation of Patients in Prone versus Supine Position in workers Undergoing Lumbar Disc Surgery
Introduction: This study compared the extubation of patients in prone versus supine positions in patients undergoing lumbar disc surgery. Methods: In this single-blind clinical trial, 60 patients who were candidates for elective lumbar disc surgery were selected and randomly assigned into two groups of 30 patients. All patients primarily underwent surgery in the prone position. After surgery a...
متن کاملEffect of Reducing Abdominal Compression during Prone CT Colonography on Ascending Colonic Rotation during Supine-to-Prone Positional Change
OBJECTIVE To determine the effect of reduced abdominal compression in prone position on ascending colonic movement during supine-to-prone positional change during CT colonography (CTC). MATERIALS AND METHODS Eighteen consecutive patients who had undergone prone CTC scanning with cushion blocks placed under the chest and hip/thigh to reduce abdominal compression and had confirmed sessile polyp...
متن کاملDeformable Registration of Supine and Prone Colons for CT Colonography
CT colonography (CTC) is a minimally invasive screening technique for colorectal polyps and colon cancer. Most CTC protocols acquire both prone and supine images to improve the visualization of the lumen wall, reduce false positives, and improve sensitivity. Comparisons between the prone and supine images can be facilitated by computerized registration between the scans. In this paper, an algor...
متن کاملExternal Clinical Validation of Prone and Supine CT Colonography Registration
This paper provides an external validation of a prone-supine registration algorithm for CT colonography (CTC). A validation sample of 49 patient cases with 66 polyps (6 to 30mm) was selected from a publicly available, anonymized CTC archive. To enhance generalizability, no case was excluded due to poor preparation or inadequate distension. Corresponding prone and supine polyp coordinates were r...
متن کاملEmergence from anesthesia in the prone versus supine position in patients undergoing lumbar surgery.
BACKGROUND Conventional supine emergence in patients undergoing prone lumbar surgery frequently results in tachycardia, hypertension, coughing, and loss of monitoring as the patient is rolled supine. The prone position might facilitate a smoother emergence because the patient is not disturbed. No data describe this technique. METHODS Fifty patients were anesthetized with fentanyl, nitrous oxi...
