Surgical procedures on obese patients are dramatically increasing worldwide over the past few years. In this review, we discuss the physiopathology of predominantly respiratory system in obese patients, the importance of preoperative evaluation, preoxygenation and intraoperative positive end expiratory pressure (PEEP) titration to prevent pulmonary complications and the optimization of airway management and oxygenation to reduce or prevent postoperative respiratory complications. ⋯ Obese patients are at higher risk of perioperative complications, mainly associated with those related to the respiratory function. An appropriate preoperative evaluation, intraoperative management, and postoperative support and monitoring is essential to improve outcome and increase the safety of the surgical procedure.

ReviewFailed spinal anesthesia for cesarean delivery: prevention, identification and management.
There is an increasing awareness of the significance of intraoperative pain during cesarean delivery. Failure of spinal anesthesia for cesarean delivery can occur preoperatively or intraoperatively. Testing of the neuraxial block can identify preoperative failure. Recognition of the risk of high neuraxial block in repeat spinal in case of preoperative failure is important. ⋯ Block testing is crucial to identify preoperative failure of spinal anesthesia. Repeat neuraxial is possible but care must be taken with dosing. In this situation, switching to a combined spinal epidural or an epidural technique can be useful. Intraoperative pain must be acknowledged and adequately treated, including offering general anesthesia. Preoperative informed consent should include block failure and its management.

ReviewThe intersection of pediatric anesthesiology and social determinants of health.
There is increasing evidence of racial and ethnic disparities in pediatric perioperative care, which indicates a need to identify factors driving disparities. Social determinants of health (SDOH) play a fundamental role in pediatric health and are recognized as key underlying mechanisms of healthcare inequities. This article summarizes recent research exploring the influence of SDOH on pediatric perioperative outcomes. ⋯ The existing literature offers compelling evidence of the impact of SDOH on perioperative outcomes in children and reveals a critical area in pediatric anesthesia that necessitates further exploration and action. To improve outcomes and address care inequities, future efforts should prioritize the integration of SDOH assessment into pediatric perioperative research and practice.

ReviewThe importance of simulation-based multi professional training in obstetric anesthesia: an update.
Simulation-based training remains an integral component of medical education by providing a well tolerated, controlled, and replicable environment for healthcare professionals to enhance their skills and improve patient outcomes. Simulation technology applied to obstetric anesthesiology continues to evolve as a valuable tool for the training and assessment of the multidisciplinary obstetric care team. ⋯ The evolution of simulation for interdisciplinary training and assessment in obstetric anesthesia has accelerated, playing a greater role in aspects of communication, management of hemorrhage and supporting low or strained resource settings. Augmented reality, virtual reality and mixed reality have advanced dramatically, spurred on by the need for remote and asynchronous simulation-based training during the pandemic.

The worldwide leading cause of maternal death is severe maternal hemorrhage. Maternal hemorrhage can be profound leading to an entire loss of blood volume. In the past two decades, Patient Blood Management has evolved to improve patient's care and safety. In surgeries with increased blood loss exceeding 500 ml, the use of cell salvage is strongly recommended in order to preserve the patient's own blood volume and to minimize the need for allogeneic red blood cell (RBC) transfusion. In this review, recent evidence and controversies of the use of cell salvage in obstetrics are discussed. ⋯ Intraoperative cell salvage is a strategy to maintain the patient's own blood volume and decrease the need for allogeneic RBC transfusion. Historically, cell salvage has been avoided in the obstetric population due to concerns of iatrogenic amniotic fluid embolism (AFE) or induction of maternal alloimmunization. However, no definite case of AFE has been reported so far. Cell salvage is strongly recommended and cost-effective in patients with predictably high rates of blood loss and RBC transfusion, such as women with placenta accreta spectrum disorder. However, in order to ensure sufficient practical experience in a multiprofessional obstetric setting, liberal use of cell salvage appears advisable.
