What is the Relationship of Increased Intraocular Pressure and Body Mass Index in Patients Undergoing Robotic Prostatectomy in Sleep Trendelenburg Position?

Introduction: Robotic Prostatectomy is a common procedure performed in surgery centers all over the world, but these procedures can be long and difficult to manage for Anesthesia providers. This study examined the relationship between increased intraocular pressure (IOP) and Body Mass Index (BMI) during Robotic Prostatectomies in Steep Trendelenburg (ST) position. Other variables studied were length of procedure, age, and ASA physical classification. Methodology: The study was a retrospective cross-sectional design of 100 patients with a BMI over 30 and 100 patients with a BMI under 30 who have undergone Robotic Prostatectomies at Charleston Area Medical Center (CAMC) between January 14, 2007 and January 14, 2017. Results: Conjuctival Edema was not found documented in any patient record during data collection. Discussion: Patients with a higher BMI are more likely to be classified as a ASA physical classification III and patients with a lower BMI are more likely to be classified as an ASA physical classification II. Patients with a BMI over 30 were exposed to longer procedure times. Conclusions: No relationship was found between BMI and IOP. However, patients with a higher BMI had a longer procedure time and higher ASA physical classification. Implications/Recommendations: Future researchers can utilize a prospective design to create an assessment form specifically for charting cunjuctival edema. Health care professionals could also be taught how to recognize increased IOP as conjuctival edema and treat it appropriately for the benefit of the patient prior to the study
