In rapid sequence induction of anaesthesia in the emergency setting in shocked or hypotensive patients (e.g. ruptured abdominal aortic aneurysm, polytrauma or septic shock), prior resuscitation is often suboptimal and comorbidities (particularly cardiovascular) may be extensive. The induction agents with the most favourable pharmacological properties conferring haemodynamic stability appear to be ketamine and etomidate. However, etomidate has been withdrawn from use in some countries and impairs steroidogenesis. Ketamine has been traditionally contra-indicated in the presence of brain injury, but we argue in this review that any adverse effects of the drug on intracranial pressure or cerebral blood flow are in fact attenuated or reversed by controlled ventilation, subsequent anaesthesia and the greater general haemodynamic stability conferred by the drug. Ketamine represents a very rational choice for rapid sequence induction in haemodynamically compromised patients.

Background: The rapid advancement of minimally invasive surgical techniques has made laparoscopy a preferred alternative because it reduces postoperative complications. However, inflating the peritoneum with CO2 causes a cranial shift of the diaphragm decreasing lung volume and impairing gas exchange. Additionally, CO2 absorption increases blood CO2 levels, further complicating mechanical ventilation when the lung function is already compromised.

Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes.

Laparoscopic cholecystectomy has become the gold standard for treating symptomatic cholelithiasis due to its minimally invasive nature and faster recovery times compared to traditional open surgery, but it is not without risks. A key component of this procedure is the creation of pneumoperitoneum. This is achieved by insufflating the abdomen with carbon dioxide (CO2).

Background: Immune effector cell (IEC) therapies, including chimeric antigen receptor (CAR)-modified T-cell therapy, have shown efficacy in pediatric B-cell acute lymphoblastic leukemia (B-ALL) and are being investigated for other malignancies. A common toxicity associated with IEC therapy is cytokine release syndrome (CRS), which can lead to cardiovascular decompensation due to systemic inflammation. Data are limited regarding cardiovascular adverse effects in children.

Generalized arterial calcification of infancy is a rare entity with poor fetal and postnatal outcomes and high morbidity in survivors. Half of the cases are diagnosed intrauterine due to hemodynamic compromise, and the associated manifestations pose unique management challenges. We hereby report an account of a fetal diagnosis in a referral for hydrops with postnatal evaluation and management.
