Combined Plexus Block for Hip Fracture Surgery.

Hip fracture surgery requires high risk anesthetic procedure for elderly patients (1). General anesthesia, continuous spinal anesthesia and peripheral nerve blocks are three anesthetic techniques possible. Continuous spinal anesthesia has proven its efficacity to provide an intraoperative haemodynamic stability wich guarantees good patients outcomes (2), in comparison with general anesthesia but there is poor evidence in the literature concerning the use of peripheral nerve blocks.

The primary objective of this study was to compare intraoperative haemodynamic stability provides by peripheral nerve block versus general anesthesia and continuous spinal anesthesia.

Secondary outcomes included : use of vasoactive drugs, opioids consumption, lengh of stay and inhospital mortality.

About this study

After receiving the ethic approval from the "CERAR", the investigators retrospectively identified all patients who underwent hip fracture surgery from January 1 2015, to December 31, 2016 in the CHU of Montpellier. The exclusion criteria were: multiple trauma victims, two hip fractures in the same patient and single shot spinal anesthesia. In our institution the investigators used to perform three types of anesthesia: general anesthesia (GA), continuous spinal anesthesia (CSA) and combined plexus blocks (CPB). The investigators therefore made three groups GA, CSA and CPB and used a propensity score to make these groups comparable. The matching criteria were age, arterial hypertension, ASA status, Frailty score, chronic cardiac failure and type of surgery.

Observational study

Primary outcomes

  1. Intraoperative hypotension

    Time frame: 1 day

    Decrease of at least 30% of mean arterial pressure

Secondary outcomes

  1. measure the total consumption of the vasopressive molecules

    Time frame: 1 day

    measure the total consumption of the vasopressive molecules (necessary when the voltage drops by more than 30% compared to the average reference voltage) : Use of vasoactive drugs

  2. Length of stay

    Time frame: 1 day

    Length of stay

  3. compare the use of emergency antalgics

    Time frame: 1 day

    compare the use of emergency antalgics : opioids consumption

  4. Inhospital mortality

    Time frame: 1 day

    Inhospital mortality
