With an opioid crisis at its peak, physicians need to be more cognizant of the various pain modalities available to patients. Gabapentinoids are one of the many non-opioid options to help with acute and chronic pain.
Myxoma is the most common primary benign cardiac tumor, which could lead to some fatal complications because of its strategic position. Although any age can be affected, it predominates in the age group of 30-60 years of age with more than 75% of the affected being women. The occurrence of myxomas in left and right atrium are 75% and 20% respectively.The majority of myxomas present with systemic emboli, fever and/or weight loss, or intracardiac obstruction to blood flow.1 A ‘tumor plop’ is a sound that typically occurs during early diastole and is believed to be caused by motion of the tumor striking the wall of the endocardium. The treatment is surgical excision and key aims of anesthesia care include constant monitoring of systemic blood pressure, adequate IV fluids, and judicious use of vasoactive medications to prevent a fall in systemic vascular resistance.3
Assess patient symptomatology: SOB, chest pain, changes in pulse pressure/CVP with positioning, heart sounds
Adequate PIV access
Vasopressors to help with SVR and heart rate control – mass can act as stenotic valve
Induction: maintain SVR and consider slowing heart rate if mass blocking valves
Methadone for perioperative pain #methadone #pain #ERAS
There’s a lot of great data that methadone use decreases postoperative narcotics use in cardiac surgery patients, and I believe it would really be a beneficial drug in an ERAS pathway for early extubation, decreased LOS in ICU and hospital, and better patient satisfaction. Please see the articles below/attached for references.
I had a patient come in for a 2 stage endovascular aortic repair. The patient had a 1st stage left carotid to subclavian bypass done about 3 days ago. We did a 2nd stage TEVAR for a descending aortic aneurysm. The patient did really well. Stayed in constant communication with the vascular surgeon as well as endovascular surgeon. A plan was in place. Patient was maximally beta blocked. I found dexmetetomidine to be a great drug for sedation pre-induction as well as blunting any responses to laryngoscopy during induction. Cordis for volume. Used the side port of the cordis for drips (nicardipine, phenylephrine). There were various times during the surgery where the surgeon wanted hypotension vs. hypertension. During deployment of the stent, SBP < 90. Once the stent was deployed, goal SBP 140 (MAP>90). Overall great case and great outcome for the patient.
What is a TEVAR (Thoracic EndoVascular Aortic Repair)?
I have been utilizing ERAS in general surgery, OB, and ortho cases. Diving into one of my more tricky populations, I opted to see what ERAS practices are out there for cardiac surgery. Careful what you look for my friends. There’s actually a good amount of information out there!
There’s been a big debate re: who should care for LVAD patients… a general anesthesiologist or a cardiac anesthesiologist? See below for pros and cons of each. Ultimately, I think all anesthesiologists should be comfortable caring for these patients as we’ll see more and more LVAD patients undergoing procedures.
Goals of care for LVAD patients undergoing non-cardiac surgery should be directed at maintaining forward flow and adequate perfusion. Three main factors that affect LVAD flow are preload, RV function, and afterload.
The right ventricle is the primary means of LVAD filling; therefore, maintaining RV function is imperative.
Marked increases in systemic vascular resistance should be avoided.
Generally, decreases in pump flow should first be treated with a fluid challenge. Hypovolemia should be avoided and intraoperative losses should be replaced aggressively. Second line treatment should include inotropic support for the right ventricle.
Low-dose vasopressin (<2.4 U/h) may be the vasopressor of choice due to its minimal effect on pulmonary vascular resistance.
Standard Advanced Cardiovascular Life Support Guidelines should be followed; however, external chest compressions should be avoided during cardiac arrest.
Steep Trendelenburg may increase venous return, risking RV strain. Peritoneal insufflation for laparoscopic surgery also increases afterload and has detrimental effects on preload. Insufflation should utilize minimum pressures and be increased in a gradual, step-wise fashion.
TEE can be extremely valuable in diagnosing the cause of obstruction.
