About this study

Surgical trauma causes nerve sensitization leading to amplification and prolongation of postoperative pain. In experimental studies, pre-injury neural blockade using local anesthetics has been shown to reduce post-injury sensitization of the central nervous system, while similar techniques applied after the injury had less or no effect (FILOS). Investigators have therefore designed this study to examine the timing of FICB (pre-operatively versus intra-operatively) on postoperative pain in patients undergoing anterior hip replacement surgery.

Read the detailed description

Though still uncommonly used in the United States, the popularity of the anterior approach for total hip replacement is rapidly growing because of its clinical advantages. Rehabilitation is simplified and accelerated, dislocation risk is reduced, leg length is more accurately controlled, and incision is smaller than with traditional approaches (GOEBEL). Nevertheless, although pain is lessened, it is still considerable, and new techniques have been developed to improve postoperative pain control for this procedure.

Surgical incision and tissue trauma result in postoperative pain. Regional pain blocks, especially when done under ultrasound guidance, have proven to be extremely effective at reducing postoperative pain and improving patient satisfaction. One such block, the fascia iliaca compartment block (FICB), has been shown to be effective in controlling pain associated with surgery involving the hip and femur.

Although possible without ultrasound guidance, using this technique allows for identification of specific tissue planes and precise placement of medication near the nerves responsible for postoperative pain. Using ultrasound, the superficial fascial layer of the iliopsoas muscle is identified at the anterior edge of the ilium, and a needle is placed just beneath that fascia. A high volume of local anesthetic is then injected under ultrasound guidance, ensuring cephalad spread of medication, in an attempt to provide anesthesia of the lateral femoral cutaneous, femoral and obturator nerves.

Unlike other approaches to hip replacement, anterior repair allows for direct visualization of the fascial layers described above. This allows for direct injection of local anesthetic beneath this fascia, potentially obviating the need for preoperatively performed, ultrasound guided, FICB. The primary differences in approach (ultrasound guided preop versus direct visualization intraop) is the timing of injection, and it is unclear if nerve block prior to or after tissue damage affects postoperative pain in these patients.

Surgical trauma causes nerve sensitization leading to amplification and prolongation of postoperative pain. In experimental studies, pre-injury neural blockade using local anesthetics has been shown to reduce post-injury sensitization of the central nervous system, while similar techniques applied after the injury had less or no effect (FILOS).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pre-operative Ultrasound FICB GroupProcedure or surgery

    Enrolled subjects will receive FICB with 50cc of 0.3% ropivacaine. Blocks will be performed under ultrasound guidance with an in-plane technique by a single study investigator in the preoperative area. Although possible without ultrasound guidance, using this technique allows for identification of specific tissue planes and precise placement of medication near the nerves responsible for postoperative pain. Using ultrasound, the superficial fascial layer of the iliopsoas muscle is identified at the anterior edge of the ilium, and a needle is placed just beneath that fascia. A high volume of local anesthetic is then injected under ultrasound guidance, ensuring cephalad spread of medication in an attempt to provide anesthesia of the lateral femoral cutaneous, femoral and obturator nerves.

  • Intra-operative FICB GroupProcedure or surgery

    Enrolled subjects will receive FICB with 50cc of 0.3% ropivacaine. Blocks will be performed intra-operatively under direct surgeon visualization, in the operating room. Unlike other approaches to hip replacement, anterior repair allows for direct visualization of the fascial layers described above. This allows for direct injection of local anesthetic beneath this fascia, potentially obviating the need for preoperatively performed, ultrasound guided, FICB.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative Pain During PACU Admission

    Pain assessments will be made by the subject using a 10.0 cm Visual-Analog scale (VAS) (scale 1-100 where 1=minimal pain and 100= worst pain imaginable) as follows at each time point:

    • Baseline assessment in Preoperative area
    • Upon arrival to the post-anesthesia care unit (PACU)
    • Every 15 min (+/- 2 minutes) thereafter and prior to any request for pain medication until PACU discharge All pain scores per subject from the time of PACU admission until discharge from PACU will be averaged to obtain one data point per subject.

    Measured: From time of PACU admission until discharge from PACU, an average of 2 hours

  2. Postoperative Pain During Recovery

    Pain assessments were made by the subject using a 10.0 cm VAS (scale 1-100 where 1=minimal pain and 100= worst pain imaginable) prior to any request for pain medication. Up to 40 values per patient were averaged.

    Measured: From discharge from PACU until discharge from hospital, an average of 2-3 days

Secondary outcomes (2)
  1. Incidence of Adverse Events

    Measure is count of participants experiencing any adverse event. Adverse events will be reported by the patient (or when appropriate, staff personnel) during hospitalization.

    Measured: From the signature on the informed consent document for the duration of the hospital stay, an expected average of 2 - 3 days.

  2. Patient Satisfaction With Postoperative Pain Control

    Patient satisfaction with postoperative pain control, using a 10 point Likert scale where 1=extremely dissatisfied and 10= extremely satisfied. Patients were called 3 weeks post-op to determine pain control satisfaction.

    Measured: At the 3 week post-op visit
