- How to Read a Study Record
Every year 350 patients undergo surgery due to colorectal cancer at Zealand University Hospital, Roskilde. The majority of the surgeries are performed using a minimal invasive laparoscopic technique where the bowl anastomosis is either hand sown or stapled. The procedure is performed, while the patient is under general anaesthesia.
An observational prospective survey from 2016-17 of sixty patients undergoing hemicolectomy at Zealand University Hospital, Roskilde has shown, that even though the patients are subjected to a multimodal analgesic regimen, a substantial amount of opioids are being administered during the first 24 hours post surgery; i.e. 51.91 mg ± 36.22 mg (Mean ± SD) of oral morphine equivalents. Sixty-five percent of the patients receive opioids at the PACU. Their maximum pain score at the PACU is registered, using a numerical rating scale of 0-10, as 3.28 ± 2.65 (Mean ± SD). So it is obvious that there is room for improvement and a reduction in the use of postoperative opioids. Thus, there is a clearly defined research problem to explore.
Currently ultrasound-guided nerveblocks are not part of the multimodal analgesic regimen.
The primary aim of this study is to investigate the efficacy of the ultrasound-guided bilateral transmuscular quadratus lumborum block on reducing postoperative opioid consumption.

- Total morphine consumption [ Time Frame: Twenty-four hours postoperative ]Data from PCA pump and patient medical record
- Pain during mobilisation [ Time Frame: Registered upon arrival at the postanaesthesia care unit (PACU) and again 30 min, 1, 2, 3, 4, 5, 6, 9, 12, 15, 18 and 24 hours postoperative. ](Numerical rating scale 0-10/10). No pain = 0, worst pain = 10.
- Pain at rest [ Time Frame: Registered upon arrival at the PACU and again 30 min, 1, 2, 3, 4, 5, 6, 9, 12, 15, 18 and 24 hours postoperative. ](Numerical rating scale 0-10/10). No pain = 0, worst pain = 10.
- An integrated assessment of longitudinally measured pain intensity and opioid consumption [ Time Frame: 0-24 hours postoperative ]
This assessment is calculated using data from outcome 1 and 2. An individual rank for pain intensity using numerical rating scale (0-10/10), 0-24 hours postoperatively and for total opioid consumption 0-24 hours postoperatively will be combined and compared with a mean rank of all patients (active and placebo). The difference between the individual rank and the mean rank will be expressed as a percentage.
