Super Obesity and Regional Anesthesia: Enhancing Feasibility Through Multimodal Imaging.

Area of Science:

• Anesthesiology
• Radiology
• Trauma Surgery

Background:

• Super-obesity presents significant perioperative risks, including comorbidities and difficult airways, complicating anesthesia management.
• Regional anesthesia offers benefits like airway preservation and superior analgesia but is technically challenging in super-obese individuals.

Purpose of the Study:

• To describe a novel preoperative computed tomography (CT)-based planning technique for regional anesthesia in super-obese trauma patients.
• To demonstrate the feasibility and success of CT-guided needle trajectory marking for regional blocks in this high-risk population.

Main Methods:

• Two super-obese trauma patients requiring regional anesthesia were evaluated.
• Preoperative scout scans were insufficient for anatomical visualization.
• Computed tomography (CT) scans were utilized to identify target depth and mark optimal needle trajectories for block placement.

Main Results:

• Preoperative CT planning successfully identified target anatomy and marked needle trajectories.
• Regional anesthesia was successfully administered in both super-obese patients, guided by CT-based planning.
• This method addressed limitations of standard imaging in visualizing complex anatomy for anesthesia.

Conclusions:

• Preoperative CT-based planning is a viable and novel strategy for achieving successful regional anesthesia in super-obese trauma patients.
• This technique enhances safety and efficacy by overcoming anatomical challenges and improving precision in block placement.
• Further research may explore wider application of CT-guided planning in complex anesthetic scenarios.
