About this study

Ureteral double J (D-J) stents have been common practice in the management of various urological conditions. D-J stents are often employed to alleviate pain, prevent infection, and clear obstructions encountered during urological treatments.

Dexmedetomidine is a selective α2-adrenergic receptor agonist ( α2- AR), offering both sedation and pain relief while preserving respiratory function. Despite these benefits, one of the potential drawbacks of this medication is its tendency to lower both heart rate and blood pressure as a result of its sympatholytic properties.

Midazolam, a drug belonging to the benzodiazepines class, is commonly used for premedication before anesthesia, procedural sedation, and managing intense agitation.

  • Renal impairment (serum creatinine >1.5 mg/dL).
  • Chronic pain syndrome.
  • Mental disorder and difficulty in communication.

Treatment and study plan

Propofol

Drug

Patients received 10 ml of normal saline injected intravenous within 10 min then intravenous propofol titrated with normal saline and injected with a dose of 1.5 mg/kg for the first bolus dose followed by intermittent doses of 20 mg per dose according to patient's needs.

Propofol and dexmedetomidine

Drug

Patients received dexmedetomidine 1 µg/kg intravenous titrated with 10 ml of normal saline injected within 10 min prior to propofol administration by 10 min. Propofol was injected with a dose of 1.5 mg/kg for the first bolus dose followed by intermittent doses of 20 mg per dose according to patient's needs.

Propofol and Midazolam

Drug

Patients received midazolam 0.05 mg/kg titrated with 10 ml of normal saline injected intravenous within 10 min prior to propofol administration by 10 min. Propofol was injected with a dose of 1.5 mg/kg for the first bolus dose followed by intermittent doses of 20 mg per dose according to patient's needs.

Primary outcomes

  1. Total propofol consumption

    Time frame: Intraoperatively

    Total propofol consumption was recorded.

Secondary outcomes

  1. Sedation level

    Time frame: 30 minutes in the recovery area

    Sedation level was assessed preoperatively, every 5 minutes during the procedure and every 10 min during stay in the recovery area by Ramsay sedation scale classified 1-6 (1= anxious, 2= calm,3= lethargic, 4= confused and responsive to auditory stimuli, 5= sluggish response to auditory stimuli, 6= No response to painful stimuli)

  2. Degree of patient satisfaction

    Time frame: 24 hours postoperatively

    Degree of patient satisfaction was assessed by using a 5 point Likert scale as follows 1. extremely dissatisfied; 2. unsatisfied; 3. neutral; 4. satisfied; 5. extremely satisfied

  3. Duration of stay in the recovery area

    Time frame: 30 minutes in the recovery area

    Duration of stay in the recovery area was recorded.

  4. Incidence of complications

    Time frame: 24 hours postoperatively

    Incidence of complications such as apnea, laryngospasm, hypotension, bradycardia, nausea, vomiting, or any other complication were recorded.
