Fifty-one patients diagnosed with nephrolithiasis requiring ambulatory surgical intervention were included in this study. There were no significant differences in measures such as age, sex, BMI nor baseline pain medication usage. Patients were prospectively randomized to either standard anesthesia methodologies or to receive 30mg of ketorolac at the time of induction; both patients and surgeons were blinded to the treatment arms. Patients with an allergy to the medication or nonsteroidal anti-inflammatory drugs (NSAIDs) were excluded from participation. Postoperative, intraoperative and combined ME requirements were calculated and multivariable regression was used to identify potential independent predictors of ME requirements.
This study concluded that the administration of a ketorolac drug during the time of standard ureteroscopy was advantageous to patient recovery; providing a 50% decrease in the amount ME needed to achieve patient satisfaction and effective pain management. Dr. Goland-Van Ryn suggested the use of this technique for all patients, excluding those with extensive comorbidities or other complexities.
Upon a moderator prompted question regarding dosages, Dr. Goland-Van Ryn commented on the lack of current standardization in the dosage of ketorolac medications that are provided at induction. He emphasized that there is a wide range of dosages given solely based on the discretion of the providing anesthesiologist, rather from scientifically established guidelines.
