Design outcomes

Primary

MeasureTime frame
Main Objective: 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;Secondary Objective: The secondary goals are to investigate pain and morphine side effects. ;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. ;Timepoint(s) of evaluation of this end point: 180 min after arrival to PACU

Secondary

MeasureTime frame
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). ;Timepoint(s) of evaluation of this end point: Assessed upon arrival at PACU and the every 30 min the next 180 min where the patient remains in the PACU
