Anesthetic Management of Severe Pulmonary Hypertension in Pregnancy.

Pregnancy entails significant changes in maternal physiology that are not well-tolerated in patients with pulmonary arterial hypertension. The profound changes in plasma volume, cardiac output, and systemic vascular resistance can lead to increased strain placed on the right ventricle, leading to right-heart failure and cardiovascular collapse. Given the complex and sometimes opposing physiologic changes, managing these patients can be challenging.

Preoperative Quadratus Lumborum Block Reduces Opioid Requirements in the Immediate Postoperative Period Following Hip Arthroscopy: A Randomized, Blinded Clinical Trial.

Purpose: To examine acute postoperative opioid consumption in patients undergoing hip arthroscopy and randomized to either receive a preoperative lateral quadratus lumborum block or sham injection.

Methods: This trial randomized 46 subjects undergoing hip arthroscopy with a single surgeon to receive a preoperative lateral quadratus lumborum block (40 mL, ropivacaine 0.25%) or sham injection.

A Challenging Cesarean Delivery and Perioperative Course in a Former Polysubstance Abuser Without the Use of Traditional Opioids.

Substance abuse is a major challenge in the United States. According to the Human Resources and Services Administration, we are in an opioid crisis with over 130 people a day dying from opioid-related drug overdoses. As awareness of this epidemic has grown, there has been an increase in patients coming in for surgery requesting a narcotic-free anesthetic.

Examination of intra-operative core temperature in joint arthroplasty: a single-institution prospective observational study.

Purpose: Peri-operative hypothermia is associated with increased blood loss, delayed wound healing, and surgical site infections. However, it is not known when or how rapidly hypothermia develops during arthroplasty. This study observed patients undergoing lower extremity arthroplasty to identify the times of greatest heat loss or gain.

It Is Not Always the Epidural: A Case Report of Anterior Spinal Artery Ischemia in a Trauma Patient.

Motor vehicle collisions impact millions of people annually resulting in multiinjury trauma. Anesthesiologists are consulted for rib fracture analgesia to improve respiratory mechanics and prevent intubation. This report describes a trauma patient who developed hypotension and lower extremity weakness after epidural placement for multiple rib fractures.

Hip Hemiarthroplasty in Two Patients with Severe Aortic Stenosis: Ethical Questions from an Anesthesiologist's Perspective.

As the population ages, geriatric patients with preexisting cardiac disease are presenting for noncardiac surgery in escalating numbers. The decision to proceed with surgery in such patients often is multifactorial. With this in mind, we describe 2 patients with severe aortic stenosis who required hip operations: one urgent and one elective.
