Background: Magnetic resonance imaging (MRI) is a useful tool, but it can be difficult to perform in those with claustrophobia as it requires being enclosed in a noisy cylindrical space. Being in the prone position is essential to spread breast tissue. However, sedation in a prone position is challenging because of the possibility of respiratory depression and the difficulty in manipulating the airway.

Case: Four patients with claustrophobia were sedated using dexmedetomidine, has minimal effect on respiration. Dexmedetomidine also enables the patient's cooperation in assuming the prone position while infusing loading time. But dexmedetomidine requires a longer time to reach moderate sedation, an intermittent bolus of midazolam was required for rapid induction of moderate sedation. All exams were conducted successfully without any complications.

Conclusions: Administering dexmedetomidine and a midazolam bolus at the appropriate dose and timing will render MRI examinations in the prone position safe and satisfactory, without respiratory complications.

Visual deficit after spinal surgery is rare but tragic. The main causes include external eye injury, cortical blindness, central retinal artery occlusion, and ischemic optic neuropathy. In scoliosis surgery, this complication potentially arises from prolonged surgical time, high blood loss, prone position, hydroelectrolytic imbalance, and cerebrospinal fluid loss.

Effects of innovative modular prone positioning tools in patients with acute respiratory distress syndrome due to COVID-19 during awake prone position: a prospective randomized controlled trial.

Eur J Med Res

December 2024

Department of Rehabilitation Medicine, Shanghai Fourth People's Hospital, School of Medicine, Tongji University, No.1279 Sanmen Road, Hongkou District, Shanghai, China.

Objectives: Our aim is to investigate the effects of a innovative modular prone positioning tools on patients with acute respiratory distress syndrome (ARDS) caused by COVID-19 during awake prone positioning (AW-PP).

Methods: This prospective randomized controlled study initially enrolled 168 patients with COVID-19 due to ARDS. However, 92 were subsequently disqualified, leaving 76 patients who were randomly assigned to either the observation group (n = 38) or the control group (n = 38).

Fully Navigated Single-Position Prone Lateral Lumbar Interbody Fusion: A Detailed Technical Report and Description of 15 Cases.

Int J Spine Surg

December 2024

Spine Team, Division of Orthopedic Surgery and Musculoskeletal Trauma Care, Geneva University Hospitals, Faculty of Medecine, University of Geneva, Geneva, Switzerland

Background: Navigation increases the precision and safety of pedicle screw placement and has been used to place interbody cages for lateral lumbar interbody fusion. Single-position surgery shortens its duration and that of anesthesia. The aim of this study was the feasibility of simultaneous cage and screw placement in a single prone position using intraoperative navigation without the need for additional fluoroscopy and a detailed technical description of this procedure.

Background: Although shock wave lithotripsy (SWL) has been considered to be effective in treating ureteral stones, a definitive conclusion remains unclear on which patient's position is the optimal option for proximal ureteral stones. The purpose of this study is to assess the ideal position of ultrasound guided SWL for the treatment of proximal ureteral stones.

Methods: This prospective study was conducted in multi-center from June 2020 to December 2023.
