Study summary

This study focused on to determine postoperative analgesic efficacy of tramadol compared to tramadol with addition of paracetamol after a lumbar disc surgery.

Read the detailed description

Background:

Despite developments in treatment of pain, the availability of new drugs or increased knowledge of pain management, postoperative pain control after different surgeries still remains inadequate.

Aims:

This study focused on to determine postoperative analgesic efficacy of tramadol compared to tramadol with addition of paracetamol after a lumbar disc surgery.

Study Design:

In this study we have randomized 60 patients into two treatment groups. In Group Tramadol patients received tramadol, In Group TramadolParacetamol patients received paracetamol 1 gr iv in addition to tramadol 30 minutes before the operation ends and 1 g at 6 hour intervals.

Methods:

Severity of the pain, total tramadol consumption, adverse effects, ramsay sedation scale score, nausea/vomiting scores, patient satisfaction score were recorded in the postoperative period.

Inclusion criteria

(ASA) 1 or 2 status patients with single level lumbar disc herniation.

Exclusion criteria

Exclusion Criteria:

Patients who could not use a patient controlled analgesia (PCA) device, known allergies to any of the drugs used in this study,hepatic and renal dysfunction, herniated disc with neurological deficit or intense pain justifying emergency surgery and the patients whose is ≥30 kg/m2 were excluded from the study.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2014 to primary completion in Jan 2015, 9 months.

Of 178 non-industry interventional studies with no phase under Intervertebral Disc Displacement, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 23. This study's 9 months is below that.

Counting every sponsor, half of 191 studies reached it within 12 months; a quarter within 5 and three quarters within 27.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 29, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
