Precision in the Smallest Spaces: Anesthetic Challenges in Neonatal Laparoscopic Pyeloplasty

Neonatal laparoscopic surgery presents unique anesthetic challenges because of the physiological vulnerability of immature organ systems, limited physiological reserve, and extremely small working space available for surgery. Pelvi-ureteric junction obstruction (PUJO), a common cause of antenatal hydronephrosis, often requires surgical correction early in life. Minimally invasive surgery has emerged as a better alternative to open surgery in small patients. Creation of pneumoperitoneum can significantly affect ventilation, venous return, pulmonary compliance, thermoregulation, and tissue perfusion. We describe perioperative management of a term baby with antenatal diagnosis of right PUJO, who underwent laparoscopic pyeloplasty under general anesthesia. Low-pressure carbon dioxide pneumoperitoneum and multimodal analgesia were employed to maintain cardiopulmonary stability. The intraoperative and post-operative courses were uneventful, and recovery was smooth without complications. Laparoscopic pyeloplasty can be safely performed in neonates when the physiological consequences of operating within a very small abdominal cavity are anticipated and managed using meticulous perioperative planning, controlled pneumoperitoneum, vigilant monitoring, and multimodal analgesia.
