Provide a brief summary of this surgical procedure and its indications here.

Preoperative management

Patient evaluation

System Considerations
Neurologic
Cardiovascular Evaluate for hypertension

OSA causing pulmonary arterial hypertension

Respiratory Evaluate BMI for decreased FRC

Evaluate OSA status for difficult mask ventilation

Gastrointestinal Consider delayed gastric emptying with diabetes mellitus
Hematologic
Renal
Endocrine Consider delayed gastric emptying with diabetes mellitus
Other

Labs and studies

  • sleep study (AHI score if available) for OSA

Operating room setup

  • Consider ramp for airway management
  • Consider video laryngoscopy
  • OG tube

Patient preparation and premedication

  • Minimize perioperative sedation

Regional and neuraxial techniques

Intraoperative management

Monitoring and access

  • Standard ASA monitors

Induction and airway management

  • Consider rapid sequence induction
  • Video laryngoscopy can be helpful for anticipated difficult airways

Positioning

  • Supine
  • Extreme reverse Trendelenburg (place baseboard by feet)

Maintenance and surgical considerations

  • OG tube is advanced through the surgical anastamosis to prevent backwall suturing of anastamosis
    • Surgical and anesthesia communication and coordination is important to guide OGT through anastamosis

Emergence

Postoperative management

Disposition

  • PACU

Pain management

  • Moderate pain: IV and oral narcotics

Potential complications

  • Bleeding
  • Thromboemobolic events
  • Aspiration
  • Backwall suture of anastamosis
