Latest Updates
Cardiac Patients for Non-Cardiac Surgeries
- Improved survival of patients with congenital heart disease requires all anesthesiologists to be familiar with basic pathophysiological concepts and long term problems after repair or palliation of heart defects.
- Complex congenital heart defects are nowadays often managed with staged palliations and multiple interventions in the cardiac catheterization laboratory. A thorough understanding of the physiological implications for each of these stages is important for a safe anesthetic management.
- Minimal invasive surgical techniques can have major implications for patients with single ventricle physiology.
- Recent advances in the treatment of pulmonary arterial hypertension and heart transplantations will increase the number of imaging studies and interventions for surveillance and therapy adjustments.
Surgical Management of Ulcerative Colitis
- As laparoscopic surgery becomes increasingly pervasive, both a hand-assisted and straight laparoscopic colectomy and proctectomy with ileal pouch-anal anastomosis (IPAA) have become more common, with outcomes equivalent to or even improved compared with an open approach.
- Since the introduction of infliximab, biologic therapy has become more prevalent in the inflammatory bowel disease patient population. These medications should be held as long as possible prior to an elective operation as they have been associated with increased infectious complications following IPAA.
- Despite biologic therapy, in the setting of an acute flare of ulcerative colitis, 50% of patients treated with intravenous steroids and an induction done of anti–tumor necrosis factor–α will still go on to have a colectomy within the year.
- The relatively recent introduction of enhanced recovery after surgery protocols in our postoperative care has improved postoperative pain scores and decreased the length of hospital stays. These protocols use a multimodality pain management plan that avoids systemic narcotics, minimizes intravenous fluid administration, enforced early ambulation, and early enteral intake on the night of surgery. The expected length of stay following IPAA is now typically 3 days.
- As an increasing number of immunosuppressive drugs are being introduced for the treatment of ulcerative colitis, a three-stage approach to IPAA is being more commonly employed. A three–stage approach is used for patients who require emergency surgery, are in poor medical condition due to their underlying disease, or are significantly immunosuppressed.
Liver Failure in the Critical Care Setting
- Cerebral edema and intracranial hypertension are the major cause of early mortality in acute liver failure (ALF)
- Liver transplantation is the only proven liver replacement therapy to reduce mortality
- N-Acetylcysteine (NAC) should be administered to all patients with ALF due to acetaminophen
- New methods for predicting prognosis, such as the Acute Liver Failure Study Group Index, may offer improved sensitivity in predicting the need for liver transplant or death in ALF.
- Correction of coagulopathy with fresh frozen plasma in the absence of bleeding or procedures does not improve survival and may precipitate complications.

Management of Shock in Infants and Children
- Extracorporeal membrane oxygenation (ECMO) is a modified method of cardiopulmonary bypass that is used as a last resort modality for support of the pediatric patient in cardiac and/or respiratory failure.
- VADs are a newer, alternative method of mechanical circulatory support for children in refractory heart failure or cardiogenic shock who are awaiting transplantation. VAD use in adults is well established, and its use in children has been steadily increasing over the last decade.
- Lactate is a by-product of anaerobic metabolism and is often used to diagnose and monitor the progression of shock. Although lactate is less frequently elevated in pediatric patients, an initial elevated lactate level has been found to be associated with increased risk of organ dysfunction in pediatric sepsis and can be followed as a marker of resuscitation.
- The number of permanent pacemakers implanted per year increased by 55.6% between 1993 and 2009, and is continuing to rise. Accordingly, the number of patients treated in the emergency department who have permanent pacemakers is increasing, and it is important for physicians in the emergency department to be familiar with the operation and potential complications of these devices.
- Genetic testing of first-degree relatives is recommended according to 2018 ACC/AHA/HRS guidelines on evaluation of bradycardia and conduction delay.
- Permanent pacing is reasonable intervention for patients with tachy-brady syndrome and symptoms attributable to bradycardia.
- 2018 ACC/AHA/HRS specific guideline considerations for genetic disorders, neuromuscular disorders, and infiltrative disorders (e.g., cardiac sarcoidosis and amyloidosis).
