Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A randomisation table will allocate the 70 patients in the study to either treatment or placebo. The hospital pharmacy will make up syringes containing either local anaesthetic or placebo in accordance with the randomisation table. They will then be labelled with Study Patient 1, Study Patient 2, etc. but not the contents.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated random number table will be used for sequence generation (eg. www.random.org)

Summary
Brief summary
The project aims to demonstrate that transversus abdominis plane block is an effective adjunct to multi-modal analgesia in the setting of major gynaecological surgery via midline laparotomy. The project aims to demonstrate that the technique improves overall pain relief, reduces morphine consumption (and opioid side effects) and improves patient satisfaction.
