Managing anesthesia for cesarean section in obese patients: current perspectives

Area of Science:

• Anesthesiology
• Obstetrics
• Public Health

Background:

• Obesity is a global epidemic linked to numerous maternal and fetal complications.
• Obese parturients face higher risks of cesarean delivery, difficult intubation, and anesthesia-related complications.
• Specialized anesthetic management is essential for this high-risk patient group.

Purpose of the Study:

• To outline anesthetic management strategies for obese parturients undergoing cesarean delivery.
• To highlight the importance of antenatal anesthetic consultation for risk assessment and planning.
• To discuss preferred anesthetic techniques and postoperative care for improved outcomes.

Main Methods:

• Review of anesthetic techniques for cesarean delivery in obese patients, focusing on neuraxial options.
• Discussion of intraoperative positioning, monitoring, and postoperative analgesia.
• Emphasis on thromboprophylaxis and careful postoperative surveillance.

Main Results:

• Neuraxial techniques, particularly combined spinal epidural, are preferred but challenging in obese parturients.
• Existing labor epidural catheters can be utilized; continuous spinal anesthesia is an option.
• Standard spinal bupivacaine dosing may be appropriate, though data for super-obese patients is limited.

Conclusions:

• Antenatal anesthetic consultation is vital for obese parturients requiring cesarean delivery.
• Multimodal analgesia and thromboprophylaxis are critical for postoperative recovery and complication prevention.
• Close postoperative monitoring is necessary due to increased risks in morbidly obese parturients.
