Mitral Valve Systolic Anterior Motion in Robotic Thoracic Surgery as the Cause of Unexplained Hemodynamic Shock: From a Case Report to Recommendations

Robotic major lung resection for lung cancer carries a risk for intraoperative hemodynamic instability. Systolic anterior motion (SAM) of the mitral valve is a rare and often misrecognized cause of intraoperative hemodynamic instability. If not promptly recognized, SAM leads to a complicated perioperative course. Here, we report for the first time a case of a patient with SAM with a severe degree of left ventricular outflow obstruction (LVOTO) undergoing robotic lung lobectomy and its challenging intraoperative management. A 70-year-old man undergoing robotic left upper lobectomy developed immediately after the induction of general anesthesia hemodynamic instability due to SAM-related LVOTO. The diagnosis was possible, thanks to the use of transesophageal echocardiography (TEE). The treatment strategies applied were preload optimization without fluid overload, ultra-short-acting beta-blockers, and vasopressors. Peripheral nerve blockades were preferred over epidural analgesia to avoid vasodilatation. The patient reported a good quality of recovery and no pain the day after surgery. The management of patients with higher risk of SAM and LVOTO development during robotic thoracic surgery requires a dedicated and skilled team together with high-impact treatment strategies driven by TEE. Since current guidelines do not recommend the use of TEE, even for patients with higher cardiac risk undergoing noncardiac surgery, the present case report may stimulate interest in future recommendations

Opioid Free Anesthesia in Thoracic Surgery: A Systematic Review and Meta Analysis

Introduction: Recent studies showed that balanced opioid-free anesthesia is feasible and desirable in several surgical settings. However, in thoracic surgery, scientific evidence is still lacking. Thus, we conducted the first systematic review and meta-analysis of opioid-free anesthesia in this field. Methods: The primary outcome was the occurrence of any complication. Secondary outcomes were the length of hospital stay, recovery room length of stay, postoperative pain at 24 and 48 h, and morphine equivalent consumption at 48 h. Results: Out of 375 potentially relevant articles, 6 studies (1 randomized controlled trial and 5 observational cohort studies) counting a total of 904 patients were included. Opioid-free anesthesia compared to opioid-based anesthesia, was associated with a lower rate of any complication (74 of 175 [42%] vs. 200 of 294 [68%]; RR = 0.76; 95% CI, 0.65–0.89; p 2 = 0%), lower 48 h morphine equivalent consumption (MD −14.5 [−29.17/−0.22]; p = 0.05; I2 = 95%) and lower pain at 48 h (MD −1.95 [−3.6/0.3]; p = 0.02, I = 98%). Conclusions: Opioid-free anesthesia in thoracic surgery is associated with lower postoperative complications, and less opioid demand with better postoperative analgesia at 48 h compared to opioid-based anesthesia

Association between type of anaesthesia and clinical outcome in patients undergoing endovascular repair of thoraco-abdominal aortic aneurysms by fenestrated and branched endografts

Although the endovascular repair of thoraco-abdominal aortic aneurysm (TAAA) is the treatment of choice in high-risk population not eligible for open surgical approach, little is known on the association between the type of anesthesia and complications. In the present study the short-term clinical outcomes of patients undergoing the visceral step of TAAA with fenestrated endograft aortic repair (FEVAR) and branched endograft aortic repair (BEVAR) under general anesthesia (GA) was compared to sedation with monitored care anesthesia (MAC)

Esmolol in Cardiac Surgery: A Randomized Controlled Trial

To assess whether the administration of the ultra-short-acting β-blocker esmolol in cardiac surgery could have a cardioprotective effect that translates into improved postoperative outcomes
