E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of the trial is to asses the analgesic effect of preoperatively placed active or placebo subpectineal obturator nerve block for elective primary hip arthroscopy. The primary objective of the study is to investigate morphine consumption |
Formålet er at vurdere analgetisk effekt af præoperativt anlagt aktiv eller placebo subpectineal obturatorius nerveblokade til elektiv primær hofteartroskopi. Forsøgets primære mål er at undersøge morfinforbrug. |
|
E.2.2 | Secondary objectives of the trial |
The secondary goals are to investigate pain and morphine side effects. |
Det sekundære mål er at undersøge postoperative smerter og morfinbivirkninger |
|
E.2.3 | Trial contains a sub-study | No |

E.5 End points |
E.5.1 | Primary end point(s) |
Cumulative opioidconsumption by PCA pump (patient controlled analgesia) in the first 180 min in PACU after primary hip arthroscopy for patients with active or placebo subpectineal obturator nerve block. |
Kumuleret opioidforbrug ved PKA pumpe (patient kontrolleret analgesi) de første 180 min i PACU efter primær hofteartroskopi for patienter med aktiv eller placebo subpectineus obturatorius nerveblokade |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
180 min after arrival to PACU |
180 min efter ankomst til PACU |
|
E.5.2 | Secondary end point(s) |
• Pain Score (NRS 0-10, where 0 is no pain and 10 the worst possible pain) in the hip at rest assessed on arrival at PACU and then every 30 minutes the next 180 min. where the patient remains in PACU. • Pain Score (NRS 0-10) in the hip by activity (flexion at the hip joint to 45 degrees), assessed on arrival at PACU and then every 30 minutes the next 180 min. where the patient remains in PACU. • Nausea score assessed on a scale (no, mild, moderate, pronounced) assessed on arrival at PACU and then every 30 minutes the next 180 min. where the patient remains in PACU. • Number of vomiting the first 180 min. The patient is in PACU. • Length of stay (LOS) measured in minutes in PACU. The period is registered from arrival to PACU until the patient is ready for discharge. After the first 180 min in PACU, this is assessed every 30 minutes where the patient remains in PACU. • Total morphine consumption in PACU during the first 180 min in PACU. • The force of the adductor muscles on the operated limb was tested with a dynamometer before the nerve blockade and after 180 min observation in PACU. • Patient satisfaction with pain treatment at the time of discharge (NRS 0-10, where 0 is very dissatisfied and 10 is very satisfied).

•Smertescore (NRS 0-10, hvor 0 er ingen smerte og 10 den værst tænkelige smerte) i hoften i hvile vurderet ved ankomst til PACU og derefter hvert 30. min. de næste 180 min. hvor patienten forbliver i PACU. •Smertescore (NRS 0-10) i hoften ved aktivitet (fleksion i hofteleddet til 45 grader) vurderet ved ankomst til PACU og derefter hvert 30. min. de næste 180 min. hvor patienten forbliver i PACU. •Kvalmescore vurderet på en skala (ingen, let, moderat, udtalt) vurderet ved ankomst til PACU og derefter hvert 30. min. de næste 180 min. hvor patienten forbliver i PACU. •Antal af opkastninger de første 180 min. patienten er i PACU. •Varighed af ophold (LOS) målt i minutter i PACU. Perioden registreres fra ankomst til PACU til patienten er klar til udskrivelse. Efter de første 180 min i PACU vurderes dette hvert 30. min hvor patienten forbliver i PACU. •Samlet morfinforbrug i PACU i løbet af de første 180 min i PACU. •Kraften i adductormusklerne på den opererede underekstremitet testes med et dynamometer før nerveblokade og efter 180 min observation i PACU. •Patienttilfredshed med smertebehandlingen på udskrivelsestidspunktet (NRS 0-10, hvor 0 er meget utilfreds og 10 er meget tilfreds).
