Discharge Opioids are Unnecessary Following Radical Cystectomy.

OBJECTIVE: To show that zero-opioid discharges after both open and robotic cystectomy are feasible and to examine the impact of zero-opioid discharges on patient interaction with the physician's office. MATERIALS AND METHODS: One hundred seven patients who underwent either open or robotic radical cystectomy from March 1, 2020 to December 30, 2020 were identified. Patient demographics, perioperative data, and 30 day pain related outcomes including phone calls, office visits, requests for pain medication, emergency department visits, and readmissions were abstracted from the chart. We then examined variables associated with a zero-opioid discharge. RESULTS: Thirty-two patients were discharged with an opioid prescription (Median Oral Morphine Equivalents Prescribed = 90) and 75 were discharged without an opioid prescription. On regression analysis, age (OR 1.07, 95% CI [1.02-1.12]) and pathology (OR 0.36, 95% CI[0.14-0.9]) remained significantly associated with post-operative opioid prescriptions. There were no differences in the percent of patients presenting to the emergency department, being readmitted, calling the office, calling the office regarding pain, or requesting opioid prescriptions within 30 days of discharge, or the number of post-operative office visits (P >.05 for all). CONCLUSION: Patients can safely be discharged home without opioids following cystectomy, regardless of robotic or open approach. Age and pathology are predictors of the need for an opioid prescription on discharge. These patients did not have increased follow-up visits, phone calls, or requests for pain medication.

Thrombin generation and bleeding in haemophilia inhibitor patients during immune tolerance induction.

BACKGROUND: Inhibitor formation complicates haemophilia treatment and requires immune tolerance induction to rid inhibitors over 5 BU. In the prospective, randomized International Immune Tolerance Study, immune tolerance induction was equally effective with high-dose (HD) (200 IU kg-1 day-1 ) and low-dose (LD) (50 IU kg-1 3× per week) factor VIII, but haemorrhages were twofold higher in the LD arm. This finding was unexpected as inhibitors neutralize FVIII activity. We hypothesized that the thrombin generation assay (TGA), a global measure of clot formation, might predict bleeding better than FVIII levels. METHODS: We evaluated TGA using relipidated tissue factor (TF) on 83 thawed, recalcified corn trypsin inhibitor/citrate plasma samples from 31 subjects (17 HD, 14 LD) who participated on the ITI study, and who had sufficient sample available and appropriate informed consent. RESULTS: There were no significant differences in peak thrombin, estimated thrombin potential, maximum rate or lag time between HD and LD arms; between pre-, during and post-ITI time points, or after FVIII spiking. In 19 subjects (12 HD, 7 LD) with anti-FVIII<1.0 BU, the prevalence of non-neutralizing antibody (NNA) and neutralizing antibody (NA) was 89.5% (17/19), and the latter strongly correlated with anti-VIII titer, r = 0.73 [95% CI: 0.55, 0.88]. CONCLUSION: In haemophilia inhibitor patients, thrombin generation is present, but does not predict bleeding risk. Following tolerance induction, NNA remains detectable in the majority.
