Title: The Efficacy of Continuous Intravenous Ketorolac for Postoperative Pain in Percutaneous Nephrolithotomy: a Double Blinded Randomized Placebo Controlled Trial
Brief Summary: The purpose of this study is to determine whether continuous intravenous ketorolac infusion reduces pain in patients who are having percutaneous nephrolithotomy for kidney stone disease.


Options:

* Patients undergoing percutaneous nephrolithotomy for kidney stone disease

Exclusion Criteria:

* History of nonsteroidal antiinflammatory drug allergy
* Asthma
* History of long-term opioid use
* Intraoperative blood loss greater than 300 mL
* Postoperative hemodynamic instability
* Active peptic ulcer disease
* Advanced renal impairment (Creatinine \> 2.0 mg/dL)
* Bleeding diathesis
* Current use of probenecid
* Pregnancy
B: Inclusion Criteria:

* Patients donating a kidney via laparoscopic donor nephrectomy

Exclusion Criteria:

* History of NSAID allergy
* Asthma
* History of long term opioid use
* Intraoperative blood loss greater than 300 mL
* Postoperative hemodynamic instability
* Active peptic ulcer disease
* Advanced renal impairment (Cr \> 2.0 mg/dL)
* Bleeding diathesis
* Current use of probenecid
* Pregnancy
C: Inclusion Criteria:

1. Are undergoing noncardiac surgery;
2. Are ≥ 45 years of age;
3. Are expected to require at least an overnight hospital admission after surgery; AND
4. Fulfill one or more of the following 5 criteria:

     * history of congestive heart failure
     * transient ischemic attack
     * diabetes and currently taking an oral hypoglycemic agent or insulin
     * age ≥ 70 years
     * hypertension
     * serum creatinine \> 175 µmol/L (\> 2.0 mg/dL)
     * history of smoking within 2 years of surgery
     * undergoing urgent/emergent surgery

Exclusion Criteria:

1. Consumption of ASA within 72 hours prior to surgery
2. Hypersensitivity or known allergy to ASA or clonidine
3. Systolic blood pressure \< 105 mm Hg
4. Heart rate \< 55 beats per minute in a patient who does not have a permanent pacemaker
5. Second or third degree heart block without a permanent pacemaker
6. Active peptic ulcer disease or gastrointestinal bleeding within previous 6 weeks
7. Intracranial hemorrhage documented by neuro-imaging, in the 6 months prior to randomization. This does not include petechial hemorrhagic transformation of a primary ischemic stroke
8. Subarachnoid hemorrhage or epidural hematoma unless the event occurred more than 6 months prior to randomization and the offending aneurysm or arterial lesion has been repaired
9. Drug-eluting coronary stent in the year prior to randomization
10. Bare-metal coronary stent in the 6 weeks prior to randomization
11. Thienopyridine (e.g., clopidogrel, ticlopidine, prasugrel) or ticagrelor within 72 hours prior to surgery; or intent to restart a thienopyridine or ticagrelor during the first 7 days post-op; or currently taking an alpha-2 agonist, alpha methyldopa, monoamine oxidase inhibitors or reserpine;
12. Planned use - during the first 3 days after surgery - therapeutic dose anticoagulation or a therapeutic subcutaneous or intravenous antithrombotic agent
13. Undergoing intracranial surgery, carotid endarterectomy, or retinal surgery
14. Not consenting to participate in POISE-2 prior to surgery
15. Previously enrolled in POISE-2 Trial
D: Inclusion Criteria:

* age\>18
* any cardiac procedure with sternotomy
* able to give informed consent

Exclusion Criteria:

* cardiac surgery without sternotomy
* peripheral neuropathy
* neurological disease
* psychiatric illness
* history of GI bleeding
* chronic pain (i.e. back pain, cancer, arthritis)
* serum creatinine \>150 μmol/l
* hepatic disease with elevated liver enzymes (SGPT and SGOT elevated to 1.5 times maximum normal value)
* allergic to study medication
* alcohol abuse
* abuse of narcotics or medication
* pregnancy
* participation in other clinical trials
* insufficient language skills
* In addition intensive care unit (ICU) stay for more than 24 hours was used as a pre-defined post randomization exclusion criteria, because prolonged ICU stay and ventilator treatment would interfere with study analgesic protocol.
