Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the success of the transversals fascia plane (TFP) block in producing cutaneous anesthesia proximal to - and continous with - the area of anesthesia produced by the lateral femoral cutaneous nerve (LFCN) block;Secondary Objective: -Evaluating the cutaneous anesthesia after a selective subcostal nerve block -Evaluating the cutaneous anesthesia after the TFP block;Primary end point(s): Success rate of the TFP block with local anesthetic to produce a cutaneous area of anesthesia that is continous with the anesthetized cutaneous area after a LFCN block, compared to placebo.;Timepoint(s) of evaluation of this end point: 30 minutes after relevant nerve blocks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Time needed to do the subcostal nerve block - Succes rate of ultrasonographic (US) visualization of the subcostal nerve just caudate to the 12th costa - Succes rate of US visualization of the subcostal nerve at location where the lateral cutaneous nerve is branching off - Success rate of US visualization of the subcostal lateral cutaneous nerve in its course through the external oblique muscle -Succes rate of relevant cutaneous anesthesia after subcostal nerve block - Succes rate of relevant cutaneous anesthesia after subcostal nerve block produced by the primary injection - Extent of the cutaneous area anesthetized after subcostal nerve block - Success rate of each of the incisions (cannulated screws, DHS, IM nail, anterior-, anterolateral- lateral- and posterior approach) in being completely covered by the cutaneous anesthesia after subcostal nerve block - Success rate of each of the incisions in being partly covered by the cutaneous anesthesia after subcostal nerve block -Rate of complete failure for each of the incisions to be covered by any cutaneous anesthesia after subcostal nerve block -Success rate of the LFCN block to produce a cutaneous area of anesthesia that is continous with the anesthetized cutaneous area after the subcostal nerve block on day one -Success rate of the LFCN block to produce a cutaneous area of anesthesia that is continous with the anesthetized cutaneous area after the subcostal nerve block on day one measured on a vertical line through the greater trochanter - Success rate of each of the incisions in being completely covered by the cutaneous anesthesia after subcostal nerve block and LFCN nerve block - Time needed to do the TFP block -Success rate of the TFP block with local anesthetic to produce a cutaneous area of anesthesia that is continous with the anesthetized cutaneous area after a LFCN block, compared to placebo, measured on a vertical line through the greater trochanter - Success rate of each of t | — |
