Outcome Measures

Primary Outcomes (3)

  • motor blockade onset

    Onset of motor block (defined as time in minutes from the end of drug injection intrathecally until patient is unable to move the hip, knee, and ankle)

    from injection up to Modified Bromage score 1 ( 5 minutes)

  • sesnory onset

    defined as time in minutes to reach highest sensory level) will be tested every minute after intrathecal injection until it reach the highest level. It will be assessed by pin prick and cold application

    from injection up to s1 regression ( 5 minutes)

  • post operative analgesia

    will be evaluated using a visual analog scale (VAS),

    from injection up to 24 hours post operative

Secondary Outcomes (3)

  • drop in mean blood pressure

    from injection up to 24 hours post operative

  • drop in oxygen saturation

    from injection up to24hours post operative

  • drop in heart rate

    from injection up to 24 hours post operative

Study Arms (3)
