NCT02070276

Brief Summary

Spinal anesthesia is still the regional anesthesia technique most widely employed in everyday clinical practice. The most feared and common of its well known side effects consist in an abrupt reduction of systemic vascular resistances, with consequence risk of systemic hypotension. To prevent this potentially severe complication, an adequate correction of patients' volume status through a preventive administration of fluids is widely used. However this volume repletion is commonly accomplished on an empirical basis, without having a real insight of patient hemodynamic status, carrying the risk of possible volume overload. Aim of the study is to test the clinical impact of two simple, non-invasive methods to guide volemic repletion before spinal anesthesia on the reduction of significant hypotension rate, compared to empirical fluid administration.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Systemic Hypotensions

    Primary objective is to quantify significant hypotension rate after spinal anesthesia in patients brought to euvolemia according to the Trans-Thoracic Echocardiography and PLRT (Passive Leg Raising Test), compared to patients treated with the current standard. For arterial hypotension, in accordance with the international standard definitions, now define a drop in systolic blood pressure over 50 mmHg from baseline, an absolute value of systolic blood pressure less than 80 mm Hg, a mean arterial pressure below 60 mmHg or hypotension clinically symptomatic (dizziness, pallor, sweating, nausea).

    30 minutes

Secondary Outcomes (2)

  • Pre-anesthesia Fluid Amount

    Time between operating room entry and spinal anesthesia, up to 30 min.

  • Post-anesthesia Fluid Amount

    30 minutes

Study Arms (3)

Standard Clinical Practice

NO INTERVENTION

This arm is considered the current clinical standard for spinal anesthesia; its used as a control sample and statistical reference. During the induction phase the patient is fitted with a non-invasive blood pressure monitoring, three-lead ECG, pulse oximetry and peripheral intravenous device. The pressure control is set as the standard every 5 minutes until the procedure under spinal anesthesia, the cuff pressure is placed on the arm that is going to be on top during spinal anesthesia. Data is recorded and vital signs of the patient and is put an infusion of crystalloid (0.9% NaCl or Ringer's acetate) with administration of 500 ml during the entire procedure until the beginning of the operation.

Trans-thoracic echocardiography

EXPERIMENTAL

In addition to the current clinical standard (arm A of the study) a trans-thoracic echocardiography is performed with the aim of assessing patient's volume status, identifying if he is responsive to fluid and could benefit from their administration. The echocardiography is performed with the subcostal projection to assess the size of the abdominal inferior vena cava and its collapsing during breathing. According to different pre-established parameters, the patient is defined as unresponsive to fluids or responsive. If it's not responsive, he proceed to spinal anesthesia. Otherwise investigators proceed to the administration of crystalloid (NaCl 0.9% or Hartmann's solution second clinical evaluation) and at the end he's rerun an echocardiographic assessment.

Procedure: Trans-thoracic echocardiography

Passive Leg Raising Test

EXPERIMENTAL

In addition to the arm A of the study, is performed a measurement of end-tidal CO2 (EtCO2) by trans-nasal canula with a patient positioned in semi-recumbent position. After, investigators run the Passive Leg Raising Test (PLRT): the position of the bed is changed in such manner to bring the trunk from 45° to 0° and accordingly the legs from 0° to 45°. Measurements are performed before and during the maneuver : an etCO2 increasing more than 12% from baseline was interpreted as fluid-responsive. If the patient is not responsive to fluids, the patient is moving to the spinal anesthesia. If the patient is responsive investigators proceed to bolus administration, the patient returns to the initial PLRT position and is run again the PLRT until the patient is no longer responsive to fluids.

Procedure: Passive Leg Raising Test

Interventions

Subcostal evaluation of inferior vena cava dimensions and colorability with cyclic spontaneous breathing in order to determine if the patients will be fluid responsive or not.

Trans-thoracic echocardiography

Application of this test in a standard manner in order to determine if our spontaneous breathing patients are fluid responsive before spinal anesthesia.

Passive Leg Raising Test

  • patients unable to give informed consent to communication difficulties to language barriers or processes congenital/acquired determinants of mental retard, or any reduction in their ability to understand or want to be able to give their informed consent to the study
  • patients where it is not then possible to perform spinal anesthesia for the patient's refusal to technical difficulties in sampling, clinical pathological conditions for determining a high risk of peri- procedural complications.
