Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of postsurgical catheter-related bladder discomfort after preoperative pregabalin administration | Change from preoperative status to postoperative one at 0, 1, 2, 6, 24 hours postoperatively | Assessment of discomfort will be made by a scale of four (1=no discomfort, 2=mild discomfort reported on questioning only, 3=moderate discomfort, urge to pass urine reported by the patient without questioning, 4= severe discomfort, urge to pass urine accompanied by behavioral responses, such as flailing limbs, strong vocal responses or attempts to pull the catheter out) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative pain assessed by NPRS scale (Numeric Pain Rating Scale) | Total amount of analgesics in morphine analogues administered in the first 24 hours postoperatively | The goal is to achieve pain scores\<3 as these are assessed by the NPRS scale. In order to achieve that we will record the total amount of milligrams of analogues of morphine administered in the first 24 hours postoperatively |
| Adverse effects of the drug | All adverse effects observed in the first 24 hours postoperatively | Postoperative nausea and vomiting, confusion, vertigo, blurred vision, dry mouth,sedation, dizziness |
| Assessment of postoperative sedation | In the operating theatre immediately after patient's extubation | The Ramsay Sedation Scale is used to measure different levels of sedation in medical patients (1=Patient is anxious and agitated or restless, or both 2=Patient is co-operative, oriented, and tranquil, 3=Patient responds to commands only, 4=Patient exhibits brisk response to light glabellar tap or loud auditory stimulus, 5=Patient exhibits a sluggish response to light glabellar tap or loud auditory stimulus, 6=Patient exhibits no response) |
