No quadriceps muscle weakness following anterior quadratus lumborum block compared with placebo: a randomized, non-inferiority, blinded, volunteer trial.

Background And Aims: Anterior quadratus lumborum block is a truncal block, applied in close proximity to the lumbar plexus, potentially causing lower limb weakness. This trial aimed to evaluate whether a unilateral anterior quadratus lumborum block caused quadriceps muscle weakness compared with placebo.

Methods: In this randomized, non-inferiority, triple-blind trial, 20 healthy volunteers received an active unilateral anterior quadratus lumborum block with 30 mL ropivacaine 0.

Efficacy of the intertransverse process block: single or multiple injection? A randomized, non-inferiority, blinded, cross-over trial in healthy volunteers.

Introduction: The intertransverse process block is increasingly used to ameliorate postoperative pain following a plethora of surgical procedures involving the thoracic wall. Nevertheless, the optimal approach and cutaneous extent of the sensory block are currently unknown. We aimed to further describe the intertransverse process block, single injection versus multiple injection, and we hypothesized that the single-injection intertransverse process block is a non-inferior technique.

Insignificant influence of the intertransverse process block for major breast cancer surgery: a randomized, blinded, placebo-controlled, clinical trial.

Introduction: The intertransverse process (ITP) block mimics the thoracic paravertebral block and allegedly ameliorates hemithoracic postoperative pain. However, concerning major reconstructive breast cancer surgery the modality has never been tested against placebo in a randomized clinical trial. We aimed to assess the efficacy of the multiple-injection ITP block and hypothesized that the blockade would reduce postoperative opioid consumption.

Ultrasound-guided multiple-injection costotransverse block for mastectomy and primary reconstructive surgery. A study protocol.

Background: Post-operative pain amelioration following breast cancer surgery is inconsistent. The novel multiple-injection costotransverse block (MICB) mimics the thoracic paravertebral block by possible anaesthetising the ventral rami of the thoracic spinal nerves and the sympathetic trunk. Proof of concept has been determined in a cadaveric study and needs further clinical testing.

Transmuscular quadratus lumborum block for total laparoscopic hysterectomy: a double-blind, randomized, placebo-controlled trial.

Background: The population of patients scheduled for total laparoscopic hysterectomy at our surgical center is heterogeneous concerning a multitude of demographic variables such as age, collateral surgery and malign or benign pathogenesis. A common denominator is moderate to severe postoperative pain and a substantial opioid consumption. A recent procedure specific postoperative pain management (PROSPECT) review found no gain from the regional techniques included.

Patients' experiences of postoperative intermediate care and standard surgical ward care after emergency abdominal surgery: a qualitative sub-study of the Incare trial.

Aims And Objectives: To elicit knowledge of patient experiences of postoperative intermediate care in an intensive care unit and standard postoperative care in a surgical ward after emergency abdominal surgery.

Background: Emergency abdominal surgery is common, but little is known about how patients experience postoperative care. The patient population is generally older with multiple comorbidities, and the short-term postoperative mortality rate is 15-20%.
