About

Nitu Puthanveettil is an anesthesiologist whose research focuses on optimizing perioperative care during robotic and laparoscopic surgeries, with a particular emphasis on the physiological challenges posed by patient positioning. Her most cited work investigates the relationship between fluid management and intraocular pressure (IOP) during robotic pelvic surgeries, which require steep Trendelenburg positioning—a known risk factor for elevated IOP. In a 2017 study, she demonstrated that a restrictive intravenous fluid strategy can effectively blunt the intraoperative rise in IOP, offering a practical intervention to reduce the risk of ocular complications in these procedures. This contribution addresses a critical safety concern in minimally invasive surgery, where prolonged steep positioning is common. With her work cited in the context of anesthesia and surgical safety, Puthanveettil’s research provides actionable insights for clinicians managing patients undergoing robotic pelvic surgeries. Her findings underscore the importance of tailored fluid therapy in mitigating position-related physiological changes, highlighting her role in advancing evidence-based perioperative protocols.
