On Friday 16 January at 15:00, Christian Jessen defends her PhD dissertation entitled "The Effect of Peripheral Nerve Blocks for Alleviating Pain in Elective Hip Arthroscopy Patients".

Adults undergoing hip arthroscopy frequently experience substantial postoperative pain, often requiring high doses of opioids in the recovery unit. Opioids, however, are associated with numerous side effects, creating an urgent need for safer and more effective postoperative pain management strategies.

In his PhD project, anaesthesiologist and PhD fellow Christian Jessen investigated the effect of two different peripheral nerve blocks in this patient group. Based on two randomized clinical trials, both techniques were shown to reduce postoperative opioid requirements by 50%.

In addition, the dissertation presents a newly developed nerve block, combining the two existing techniques to provide complete analgesic coverage of the hip joint.

This novel block is expected to attract significant international attention, as it may benefit all patients suffering from acute hip pain — both postoperative and traumatic.

The summary is written by the PhD student.

The defence is public and takes place in the Auditorium, Horsens Regional Hospital. Please see the press release for more information.
