AI Article Synopsis
- The study aimed to compare the effects of a 15-degree reverse Trendelenburg position with a horizontal position during functional endoscopic sinus surgery on endoscopic visibility and blood loss.
- Significant findings showed that the reverse Trendelenburg position led to a better endoscopic field of view and reduced total blood loss compared to the horizontal position, without affecting surgery time or disease severity.
- The researchers concluded that using the 15-degree reverse Trendelenburg position is beneficial in improving surgical outcomes and should be recommended for such procedures.
Article Abstract
Objective: To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP).
Study Design: A prospective, randomized controlled trial.
Setting: St Paul's Sinus Centre, Vancouver, Canada.
Subjects: Patients with chronic rhinosinusitis (CRS), with or without nasal polyposis, receiving functional endoscopic sinus surgery were included. Patients were excluded if they had severe or uncontrolled hypertension and cardiovascular disease, continued use of anticoagulants, impaired coagulation, or a sinonasal tumor.
Methods: Sixty-four patients with CRS undergoing functional endoscopic sinus surgery (FESS) were randomized to either 15-degree RTP (experimental arm) or HP (control arm) from October 2011 to February 2012. Boezaart endoscopic field-of-view grading system was the primary outcome measure. Lund-Mackay computed tomography (CT) score, total blood loss, blood loss per minute, mean arterial pressure, heart rate, anesthetic technique, and surgery time were also recorded.
Results: There was a significant difference in mean Boezaart scoring between RTP and HP: 1.66 vs 2.33 (P < .001), with RTP producing a better endoscopic field of view. There was also a lower total blood loss and blood loss per minute with RTP (P = .01, P = .03). There was no significant difference in disease severity (P > .05), time of surgery (P > .05), or mean arterial pressure (P > .05) between the 2 surgical positions.
Conclusion: The 15-degree RTP improves the endoscopic field of view and reduces blood loss during FESS. We would therefore recommend its use.

J Trauma Nurs
January 2025
Author Affiliations: Department of Neurosurgery (Dr Xiao), Department of Nursing Care, Affiliated Hospital of Chengdu University, Chengdu, China (Dr Wang).
Background: Traditional nursing care often fails to meet the complex needs of hypertensive cerebral hemorrhage patients. Limited evidence exists on the efficacy of structured nursing frameworks such as the Omaha System in postoperative care for these patients.
Objective: This study aims to evaluate the efficacy of Omaha-based extended nursing care in improving patients' outcomes.

Thoracic injuries are common, occurring in up to 60% of polytrauma patients and represent 25% of trauma deaths. Thoracic trauma frequently involves injury to the pleural space resulting in hemothorax and pneumothorax-effective management of the pleural space is essential. Reviewed in this article is management of the pleural space in chest wall trauma (including pneumothorax and hemothorax), and chest tube placement, indications for video-assisted thoracoscopic surgery, management, and complications.

Introduction: Patients with cerebral hemorrhage often require a tracheal intubation to protect the airway and maintain oxygenation. Due to the use of analgesic and sedative drugs during endotracheal intubation and the opening of the glottis may easily cause aspiration pneumonia. Ceftriaxone is a semi-synthetic third-generation cephalosporin with strong antimicrobial activity against most gram-positive and gram-negative bacteria.

Hospital Guillermo Grant Benavente, Concepción, Chile.
Unlabelled: Insulin-like growth factor 1 (IGF-1) is the main mediator of fetal growth. An association has been described between low levels of IGF-1 and the development of some morbidities such as bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) in newborns weighing less than 1500 grams or less than 32 weeks at birth.
Objective: To determine the association between serum levels of IGF-1 and morbidity in premature infants.

Background: Many studies have reported the renal outcomes and metabolic consequences after augmentation cystoplasty (AC), however few studies have discussed changes in renal tubular function. The aim of this study was to determine the prevalence of metabolic disturbances, evaluate renal tubular function and 24-hour urine chemistry to evaluate the association between metabolic alterations and urolithiasis after AC.
Methods: We investigated serum biochemistry, blood gas, and 24-hour urinary metabolic profile of children who underwent AC between January 2000 and December 2020.
