Overview

This study aims to determine whether a standardized, weight-based crystalloid fluid bolus administered preoperatively reduces the incidence of postinduction hypotension (PIH) in patients undergoing cystoscopy.

Interventions

  • Drug Lactated Ringers
    A bolus of Lactated Ringers (15mL/kg of ideal body weight) will be given to patients prior to anesthesia induction.

Primary outcome measures

  • Incidence of Postinduction Hypotension [Time frame: From the time patient enters the operating room to the end of surgery, assessed up to 24 hours.]

Eligibility criteria

Inclusion criteria

  • Age ≥ 18 years old.
  • Undergoing elective cystoscopy surgery as the primary procedure.
  • Able to provide informed consent.

Exclusion criteria

  • Emergency surgeries.
  • Past history of amputations of any body part.
  • Allergies or contraindications to any medications used in the protocol or lactated ringers.
  • Systolic heart failure with LVEF < 30% within the last year.
  • Severely depressed RV function within the last year.
  • Restrictive diastolic dysfunction within the last year.
  • Currently pregnant.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
