QLB and Laparoscopic Nephrectomy, Postoperative Pain and Recovery

December 22, 2021 updated by: Tampere University Hospital

Quadratus Lumborum Block (QLB) With and Without Dexamethasone: the Effect on Postoperative Pain and Recovery After Laparoscopic Nephrectomy

There are ca 900 new cases of kidney cancer in Finland/year. The curative therapy for kidney cancer is partial or total nephrectomy depending on the localization and the size of tumor. Main of these operations are laparoscopic.

Epidural analgesia is considered as most effective for the treatment of postoperative pain after open nephrectomy, but after laparoscopic operation parenteral and enteral opioids combined with paracetamol (acetaminophen) usually offer adequate postoperative pain relief. However, the need for opioids postoperatively may be high and side effects, such as sedation and nausea, are common. On the other hand epidural analgesia has some contraindications and risks for serious complications. Nevertheless, inadequately treated acute postoperative pain is considered as one of the main risk factors for persistent postoperative pain.

Recently quadratus lumborum block (QLB) has gained popularity in the treatment of postoperative pain after various surgeries in the area from hip to mamilla. It is more beneficial than other peripheral blocks, since it covers also the visceral nerves. A single shot QLB has reported to last up to 48 hours.

Perineural dexamethasone added to local anesthetic has been reported to prolong the duration of analgesia of the perineural nerve block, but it's effect on the duration of QLB is not known.

90 kidney cancer patients with planned laparoscopic nephrectomy aging 18-85 will be recruited based on a power calculation. The primary outcome measure is the postoperative cumulative opioid consumption. Secondary outcomes are acute pain (NRS scale), nausea, vomiting, mobilisation and long term outcomes such as quality of life and persistent pain.
