NCT04170101

Brief Summary

A clinical deep NMB might relax the anterior muscles of the upper leg better than a moderate/superficial block giving a better exposure for the surgeon with less muscle trauma by traction to expose the hip. a continuous deep NMB (group A) versus a non deep NMB (group B) having a moderate to superficial block imitating common practice today as control group. Primary objectives are surgical exposure and Secondary objectives are Muscle damage creatine kinase changes, C-reactive protein (CRP), first time leaving bed postoperative, post operative pain as measured by opioid use postoperative at 24h, with a control of max VAS score during first 24 hour, length of hospital stay (LOS), number of adverse events using the Dindo-Clavien surgical complication score, QoR15 measured at 24h on the ward.

Conditions

Outcome Measures

Primary Outcomes (1)

  • surgical exposure

    After the surgical procedure the surgeon will be asked to score the surgical conditions on an adapted five point Leiden scale (validated scale): max = 5 and best; min = 1 and worst grade 5: optimal surgical conditions, perfect access to the hip joint and excellent visibility. grade 4: good conditions: adequate surgical conditions to perform the surgery, but not optimal grade 3: just acceptable conditions, surgical procedure is jeopardized, but adequate surgical result is still obtained, eventually after additional intervention grade 2: poor conditions, exposure and handling hindered resulting in suboptimal surgical outcome requiring adaptation of procedure or interventions to improve condition. grade 1: extremely poor conditions, the surgeon is unable to work because of the inability to get access to the hip joint because of inadequate muscle relaxation and request to improve conditions first before continuing.

    from incision till end of surgery stop at day zero

Secondary Outcomes (7)

  • muscle injury

    on photo after procedure stop at day zero

  • creatinine kinase (CK)

    24 hours after surgery stop at day 1

  • C-reactive protein (CRP)

    24 hours after surgery stop at day 1

  • leaving bed

    within 24 hours postoperative stop at day 1

  • Length of stay

    measured in days up to one week post surgery stop at day 7

  • +2 more secondary outcomes

Study Arms (2)

a continuous deep NMB (group A)

EXPERIMENTAL

after 0,6 mg/kg LBW Rocuronium for intubation Rocuronium is given in a continuous infusion starting at 1 mg/kg/h and adapted to keep PTC below 5 and note.

Procedure: deep NMB

non deep NMB (group B)

PLACEBO COMPARATOR

after 0,6 mg/kg LBW Rocuronium for intubation no extra NMB is given and depth is measured by TOF/PTC to note depth.

Procedure: moderate NMB

Interventions

deep NMBPROCEDURE

0,6 mg/kg LBW Rocuronium is used to facilitate intubation, and followed by an infusion of 1 mg/kg LBW/h , further adapted to keep PTC \< 3

a continuous deep NMB (group A)
moderate NMBPROCEDURE

0,6 mg/kg LBW rocuronium is used to facilitate intubation, not followed by an infusion or extra bolus.

non deep NMB (group B)

Eligibility Criteria
