Obesity in anesthesia and intensive care

Area of Science:

• Anesthesiology
• Intensive Care Medicine
• Obesity Medicine

Background:

• Obesity is a global health epidemic impacting anesthetic and critical care management.
• Specific pathophysiological considerations, comorbidities, and complications in obese patients are crucial for effective therapy.
• Systematic perioperative risk assessment is vital for managing obese patients.

Purpose of the Study:

• To highlight the unique challenges and considerations for managing obese patients in perioperative settings.
• To discuss the implications of the 'obesity paradox' in surgical outcomes.
• To emphasize the importance of tailored physiological and pharmacological approaches.

Main Methods:

• Review of current literature on obesity, anesthesia, and intensive care.
• Analysis of perioperative risk factors in different weight categories.
• Discussion of physiological and pharmacological adaptations in obese individuals.

Main Results:

• Overweight and moderately obese patients may have lower surgical risks than normal-weight patients.
• Underweight and morbidly obese patients exhibit the highest mortality and morbidity rates.
• The 'obesity paradox' describes a potentially better survival chance for obese individuals compared to normal-weight individuals in perioperative contexts.

Conclusions:

• Improving perioperative care for obese patients requires a comprehensive approach, addressing their specific pathophysiology and associated conditions.
• Physiological and pharmacological characteristics of obese patients must be considered.
• Adequate technical equipment and skilled anesthesia teams are essential for reducing risk and ensuring therapeutic success.
