Objective: Abnormalities of water and sodium balance, including diabetes insipidus and the syndrome of inappropriate antidiuretic hormone (SIADH), are common complications of transsphenoidal surgery. Postoperative practice patterns vary among clinicians, and no consensus guidelines exist to direct their monitoring and management. We aimed to identify and compare practice patterns regarding the evaluation and management to these postoperative complications. Methods: A questionnaire was utilized to capture demographic data and practice habits in the postoperative setting. Respondents were members of the Pituitary Society, an international organization comprised of clinicians and researchers dedicated to the study of pituitary disease. Results: Eighty-six respondents completed at least part of the survey. The geographic distribution of respondents was roughly even between American and non-American practitioners. The majority of respondents practiced at academic institutions (67.4%), worked in multidisciplinary teams (88.4%), and possessed significantly greater than 10 years of clinical experience (71%). Compared to non-American practitioners, American practitioners described a shorter length of stay postoperatively (P<.001) and prescribed more restrictive volume recommendations for postoperative SIADH (P = .0035). Early career clinicians (less than 10 years in practice) checked first postoperative sodium level earlier than later career clinicians (P = .010). Conclusion: Water and sodium dysregulation are common following transsphenoidal surgery, but their management is not well-standardized in clinical practice. We created a questionnaire to define and compare practice patterns. Most respondents practice in academic settings in multidisciplinary teams. The length of clinical experience did not significantly impact practice habits. Practice location influenced length of stay postoperatively and fluid restriction in SIADH. Abbreviations: AVP = arginine vasopressin; DI = diabetes insipidus; LOS = length of stay; SIADH = syndrome of inappropriate antidiuretic hormone.
