Hemorrhagic cystitis (HC) is an important complication after haploidentical hematopoietic stem cell transplantation (haplo-HSCT) with post-transplantation cyclophosphamide (PT-CY). Sodium 2-mercaptoethanesulfonate (MESNA) can prevent bladder injury when given with PT-CY. However, the best way to deliver MESNA is not known. This study assessed the incidence of HC after haplo-HSCT with PT-CY with 2 different methods of MESNA administration. The cumulative incidence of HC was lower in patients who received MESNA as a continuous infusion compared with those who received it as an intermittent bolus (5.6% versus 27.8%; P = .01). MESNA administration as an infusion was associated with a lower risk of developing HC (hazard ratio [HR], .19; 95% confidence interval [CI], .04 to .86; P = .02) on univariate analysis. This effect remained significant after adjustment in multivariate analysis (HR, .21; 95% CI, .04 to .88; P = .03). MESNA delivered as a continuous infusion is a simple and potentially useful way to prevent HC after PT-CY.

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Kidney Transplant III: Nursing Management

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
