Morphine-Sparing Efficacy Of Parecoxib In Pain Treatment After Radical Prostatectomy (PROSTATECTOMY)

21 september 2011 bijgewerkt door: Pfizer

Randomized, Double-Blind Study Of The Morphine-Sparing Efficacy And Safety Of Parecoxib Sodium 40 Mg IV Followed By 20 Mg IV Every 12 Hours In The Treatment Of Pain Following Radical Prostatectomy

The primary objective of this study is to demonstrate the opioid-sparing efficacy of parecoxib 40 mg intravenously given as a loading dose followed by 20 mg intravenously in the 24 hours after the end of surgery.

Beschrijving

Inclusion Criteria:

  • The patient's ASA physical status is 1 or 2 and he has a low risk (i.e.,<10%) of developing an acute coronary event within the next 10 years according to the PROCAM risk assessment calculator.
  • The patient is scheduled to undergo routine radical prostatectomy performed under a standardized regimen of general anesthesia, and is expected to experience moderate to severe postsurgical pain in the absence of postoperative analgesia.

Exclusion Criteria:

  • The patient has a history of uncontrolled chronic disease or a concurrent clinically significant illness or medical condition such as a diagnosed chronic pain condition, which, in the Investigator's opinion, would contraindicate study participation or confound interpretation of the results
  • The patient has a history or current presence of congestive heart failure (NYHA II-IV), established ischaemic heart disease, peripheral arterial disease and / or cerebrovascular disease.

Interventie / Behandeling
Actieve vergelijker: Morphine plus Parecoxib
Parecoxib 40 milligrams (mg) administered intravenously immediately post surgery, followed 20 mg every 12 hours until 48 hours post surgery, total 5 doses. Participants also received Patient-Controlled Analgesia (PCA) 1 mg per dose, maximum 40 mg/4 hours, and if necessary, bolus (2 to 5 mg) before or after enabled PCA.
Actieve vergelijker: Morphine and Placebo
Matching placebo administered intravenously immediately post surgery and every 12 hours until 48 hours post surgery, total 5 doses. Participants also received PCA (1 mg per dose, maximum 40 mg/4 hours, and if necessary, bolus (2 to 5 mg) before or after enabled PCA

Tijdsspanne: baseline (end of surgery) to 48 hours post surgery
Time from last surgical stitch after prostatectomy to last administration of morphine (PCA and/or bolus).
baseline (end of surgery) to 48 hours post surgery
Amount of Blood Loss
Tijdsspanne: 48 hours post surgery
Calculated as: ([Hb g/dL]pra + RBCUduring48)-[Hb g/dL]at 48, where [Hb g/dL]pra=blood hemoglobin concentration preoperatively in grams per deciliter (g/dL), [Hb g/dL]at 48=blood hemoglobin concentration 48 hours after skin closure, and RBCUduring48=number of red blood cell units (RBCU) substituted during and after prostatectomy until 48 hours after skin closure.

Pain Intensity Score
Tijdsspanne: 12, 24, 36, and 48 hours post surgery

Pain intensity assessed immediately prior and 30 minutes after administration (admin) of study medication, participants categorized their pain intensity at rest and at movement on 0-4 numeric rating scale (NRS):0 (minimum intensity) to 4 (maximum intensity).

Movement defined as sitting up from a lying into a sitting position in bed.

Modified Brief Pain Inventory-Short Form (mBPI-sf): Pain Severity Composite Score
Tijdsspanne: 24 and 48 hours post surgery
mBPI-sf: participant-rated 11-point Likert rating scale ranging from 0 (no pain) to 10 (pain as bad as you can imagine). Pain severity index=the mean of item scores 2 to 5 (pain at its worst in past 24 hours, pain at its least in past 24 hours, average pain level, and pain right now).

Modified Brief Pain Inventory-Short Form (mBPI-sf): Pain Interference Composite Score
Tijdsspanne: 24 and 48 hours post surgery
mBPI-sf: participant-rated 11-point Likert rating scale ranging from 0 (does not interfere) to 10 (completely interferes) with functional activities (general activity, mood, walking ability, relations with other people, sleep, coughing, deep breathing, and concentration) in past 24 hours.
24 and 48 hours post surgery
Opiate Related Symptom Distress Scale (OR-SDS) Questionnaire: Overall Composite Score
Tijdsspanne: 24 and 48 hours post surgery
Participant-rated scale assessed 10 common opiate related symptoms by 3 ordinal measures: frequency (1 to 4 scale: rarely to almost constantly), severity (1 to 4 scale: slight to very severe) and bothersomeness (1 to 5 scale: not at all to very much). Frequency and severity items assigned numeric scores 1 to 4. Bothersomeness items scaled in order to assign numeric scores 0.8 to 4.0 (not at all scored=0.8, a little bit=1.6, somewhat=2.4, quite a bit=3.2, and very much=4.0). Overall composite score=mean of each 10 individual mean symptoms' OR-SDS scores; ranged from 1 to 4.

OABS comprised of scores for symptoms (vomiting, itching, sweating, freezing, and dizziness) and patient satisfaction; Participants asked how much did symptoms distress and bother them during the last 24 hours; Participants asked how satisfied they have been with treatment of pain during last 24 hours. Each symptom and satisfaction question scored from 0 (not at all) to 4 (very much so). Total possible score=0 to 24.
